Earlier this week, Orbital ATK’s Cygnus cargo capsule, which has been attached to the International Space Station for the past few months, was filled up with more than 4,000 pounds of trash and released from the station out into space. A few hours later, a fire started inside the vehicle’s gut.

Multiple cameras and sensors gathered data about the blaze

Don’t fear, it was all apart of a NASA science experiment called Saffire-I — short for "safe fire" — which aims to study how fires behave in microgravity. For the test, a cotton-fiberglass material measuring 1.6 feet by 3.2 feet was lit on fire inside the Cygnus, while multiple cameras and sensors gathered data about the blaze. It was the largest controlled fire ever in space. NASA will be downloading all the data collected over the past week while the Cygnus is in space, but the space agency already posted a few videos from the experiment showing how the fire spread.

The first video shows how the smoke trails flow over the material, which is lit up green with LED lights.

After that, the fire starts, looking a bit like orange waves undulating across the green material. The entire burn lasted eight minutes, according to NASA.

Fires are a bit more unpredictable in space, due to the lack of gravity. Here on Earth, we can expect a flame to move up. A candle flame, for instance, heats up the surrounding air, causing those gases to rise and shape the flame upward. Cooler, heavier air moves down to take the place of the rising hot air, which helps to keep the flame going by replenishing the fuel. In space, air doesn’t weigh anything, so there’s no rising or falling of gases. Thus, candle flames form little spheres in space instead, as well as burn much more slowly and more cooly.

NASA has learned a lot about fire through experiments on the ISS, but all those combustions have been pretty small in order to limit mishaps. But since Cygnus is uncrewed, scientists could light a bigger fire without endangering astronauts. "Will an upward spreading flame continue to grow or will microgravity limit the size? Secondly, what fabrics and materials will catch fire and how will they burn?" says David Urban, the principal investigator of the experiment, in a statement. Hopefully, NASA will get the answers to those questions with this most recent experiment. If not, another Saffire experiment will launch on the next Cygnus capsule, and the space agency has ideas for even more flame tests.

As for this Cygnus, it will experience an even bigger fire soon. The spacecraft will deploy some satellites in the next few days and then on June 22nd, it will deorbit and burn up in Earth's atmosphere.

Lesson: The Science of Fire in Microgravity

Introduction:
Fire is an important part of our daily lives, both in good ways and bad. We use fire for cooking, heating, and light, but it can also be dangerous if not handled properly. In this lesson, we will learn about the science of fire in microgravity.

Section 1: What is Microgravity?
Microgravity is a condition where objects or people are in a state of free fall, meaning they are not experiencing the force of gravity. This is often experienced in space, where there is no atmosphere to slow down objects.

Section 2: How Does Fire Behave in Microgravity?
In microgravity, fire behaves differently than on Earth. For example, it can spread more quickly and easily because there is no resistance from the air. This is why it is important to study fire in space.

Section 3: The Saffire-I Experiment
NASA conducted an experiment called Saffire-I to study how fire behaves in microgravity. They lit a cotton-fiberglass material on fire inside the Cygnus spacecraft, which was filled with trash. Multiple cameras and sensors gathered data about the blaze.

Section 4: The Data Collected
The data collected during the Saffire-I experiment will help scientists understand how fires behave in microgravity. This information could be used to improve safety measures for future space missions.

Section 5: Conclusion
In this lesson, we learned about the science of fire in microgravity. We learned that microgravity affects the way fire behaves, and we explored the Saffire-I experiment. By studying fire in space, we can improve safety measures for future space missions.

Glossary:
- Microgravity: A condition where objects or people experience free fall, meaning they are not experiencing the force of gravity.
- Saffire-I: An acronym for "safe fire," an experiment conducted by NASA to study how fires behave in microgravity.
- Cotton-fiberglass material: A type of material used in the Saffire-I experiment.

Conclusion:
In this lesson, we learned about the science of fire in microgravity and how it differs from fires on Earth. By studying fire in space, we can improve safety measures for future space missions.


text: To investigate the basis for widely disparate rates in the diagnosis of childhood hyperactivity between the U.S. and U.K., research teams and clinician panels in both countries rated a set of 36 standardized case histories, using both ICD-9 and DSM-III diagnostic schemes. Half of the cases had brief videotaped interviews. The rates for diagnosis of hyperactivity were affected by the diagnostic scheme, being considerably lower with ICD-9, which permits only one Axis I diagnosis. This effect was principally for British raters. With DSM-III, the rates were similar for British and American raters. Inter-rater agreement was acceptably high only for specially trained research teams: Within panels of experienced diagnosticians there was much disagreement. The presence of a videotape of part of the psychiatric interview did not affect inter-rater agreement.

Lesson: Comparing Diagnostic Schemes for Childhood Hyperactivity

**Introduction:** In this lesson, we will learn about the differences between two diagnostic schemes used to diagnose childhood hyperactivity, the ICD-9 and DSM-III. We will also explore how these schemes affect the rates of diagnosis and the importance of inter-rater agreement.

**Section 1: Diagnostic Schemes**

A diagnostic scheme is a set of rules or criteria used to classify and diagnose medical conditions, including mental health disorders like childhood hyperactivity. Two commonly used diagnostic schemes for childhood hyperactivity are the International Classification of Diseases, Ninth Revision (ICD-9) and the Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III).

**Section 2: Rates of Diagnosis**

The rates of diagnosis for childhood hyperactivity can vary depending on the diagnostic scheme used. In a study comparing the ICD-9 and DSM-III diagnostic schemes, researchers found that the rates for diagnosis of hyperactivity were affected by the diagnostic scheme, with the ICD-9 scheme resulting in considerably lower rates of diagnosis compared to the DSM-III scheme. This effect was primarily observed in British raters.

**Section 3: Inter-Rater Agreement**

Inter-rater agreement refers to the degree of consistency among different raters or evaluators when assessing a particular condition or behavior. In the study mentioned above, inter-rater agreement was found to be acceptably high only for specially trained research teams. Within panels of experienced diagnosticians, there was much disagreement, highlighting the importance of proper training and expertise when diagnosing childhood hyperactivity.

**Section 4: Videotaped Interviews**

In some cases, videotaped interviews were used to aid in the diagnosis of childhood hyperactivity. However, the presence of a videotape of part of the psychiatric interview did not affect inter-rater agreement, indicating that other factors may play a more significant role in the diagnostic process.

**Conclusion:** In conclusion, understanding the differences between diagnostic schemes and the importance of inter-rater agreement is crucial in accurately diagnosing childhood hyperactivity. By examining the various factors that influence diagnosis, such as the diagnostic scheme used and the level of expertise of the evaluator, we can better understand how to apply these skills to new problems and improve the accuracy of diagnoses.

**Glossary:**
- Diagnostic scheme: A set of rules or criteria used to classify and diagnose medical conditions.
- Inter-rater agreement: The degree of consistency among different raters or evaluators when assessing a particular condition or behavior.
- Hyperactivity: Excessive motor activity or restlessness, often seen in children with attention deficit hyperactivity disorder (ADHD).
- ICD-9: The International Classification of Diseases, Ninth Revision, a diagnostic scheme used to classify and diagnose medical conditions.
- DSM-III: The Diagnostic and Statistical Manual of Mental Disorders, Third Edition, another diagnostic scheme used to classify and diagnose mental health disorders.


text: Occupational health professionals will assess aspects of your physical and mental health in order to prevent both work and non-work related illnesses or to help you make the transition back into work following an illness. For many this means a lorry driver completing a pre-employment medical, or a builder being judged fit enough to climb a ladder, but in reality every job carries occupational hazards which can affect our health. An occupational health professional is qualified to assess these risks and work with individuals and organisations to minimise these risks by putting in preventative support measures. Occupational health is often part of an employee assistance programme, giving staff a bank of support services such as a 24-hour helpline or counselling.

Q:

Kinect photo gallery - how to?

I want to create my first kinect application which is will be a grid gallery where the user can click to enlarge and read description. All the data is stored in a xml file. I've never used kinect so I would like some advice on the best way to achieve it. I've made similar applicatios with as3, it is possible, for example,  to replace the mouse input with a gesture?
Thanks.

A:

If you prefer working in ActionScript, there is AIRKinect. It features a complete Kinect data access layer, but nothing beyond that. You will have to implement gesture recognition yourself.
Performance-wise, doing Kinect stuff with AIR is a bad idea from my experience. Using C# with the official Kinect for Windows SDK is much faster and, in my opinion, easier to use. Some tutorials and documentation can be found here.
This SDK doesn't provide gesture recognition out of the box either, so you might want to give Kinect DTW a try. Others are available - Google will help.
Your question was basically if one could replace mouse input with a gesture. You certainly can. Just cause whatever action you want when a certain gesture is performed.
As for selecting photos, in case of C#/WPF, you can modify the mouse position while it's inside the window. You can use one of the hand joints from skeleton tracking to calculate an appropriate mouse position.
For the actual act of selection (which would usually be the click) I don't recommend gestures. Commercial Kinect applications prefer the approach of a visual timer counting down as soon as hovering over a button, and activating it as soon as time's up. This approach avoid the problem of accidently moving your hand to a different position while performing a gesture.
You asked a really broad question, so all I can do for now is give you some pointers. With the resources linked in this answer, you should be armed and ready to get started on your own. Best of luck!

# Lesson 1: Understanding Kinect

## Introduction

Kinect is a motion sensing input device developed by Microsoft for Xbox 360 and Xbox One video game consoles. It enables users to interact with their console through body movements, without the need for a controller. In this lesson, we will learn about the basics of Kinect and how it works.

## Section 1: What is Kinect?

Kinect is a device that uses a combination of infrared and depth sensors to capture the user's body movements and translate them into an electronic signal. This signal is then processed by the console to perform various actions, such as navigating menus, playing games, or controlling media playback.

## Section 2: How does Kinect work?

Kinect works by emitting a series of infrared lights that bounce off the user's body and return to the sensor. The sensor then measures the time it takes for the light to return and calculates the distance between the user and the sensor. By comparing the distances between the user's body parts, Kinect can determine the user's skeletal structure and track their movements accurately.

## Section 3: Applications of Kinect

Kinect has many applications, including gaming, fitness, and healthcare. In gaming, Kinect allows players to control characters and objects using their body movements. In fitness, Kinect tracks the user's movements and provides feedback on their posture and form. In healthcare, Kinect can be used to monitor patients' movements and provide therapy for people with physical disabilities.

## Section 4: Conclusion

In this lesson, we learned about Kinect, how it works, and its various applications. We also explored the basics of how Kinect captures and processes body movements to create an electronic signal. By understanding these fundamentals, we can begin to explore the endless possibilities of Kinect and how it can be used to enhance our lives.

## Glossary

- Kinect: A motion sensing input device developed by Microsoft for Xbox 360 and Xbox One video game consoles.
- Infrared: A part of the electromagnetic spectrum that is not visible to the human eye, but can be detected by electronic devices.
- Depth sensor: A sensor that measures the distance between objects.
- Skeletal structure: The arrangement of bones in the human body.
- Posture: The position of the body when standing, sitting, or lying down.
- Form: The shape or manner in which something is done or created.


text: The inspiration for Pangea was born out of the most eastern and far-reaching place that a work of Nick’s had ever travelled, Moscow. He has used butterflies stemming from all known butterfly regions in the world. With the exception of the polar regions of the globe, and those areas where extremes of temperature are prevalent, butterflies are found everywhere on dry land. These areas are divided into five arbitrarily named faunistic regions, each characterized by it’s own type of butterfly fauna; the Holarctic, Afro-Tropical, Oriental, Neo-Tropical and Australian regions. Nick has created a super-continent of butterflies in this series of works and integrated a mirrored effect to reflect the shifting movement of the butterflies and plate tectonics; the earths lithosphere gliding over the mantle.

Lesson: Plate Tectonics and the Supercontinent Pangaea

## Introduction
In this lesson, we will learn about plate tectonics and the supercontinent Pangaea. We will start by understanding the basics of plate tectonics and then move on to learn about the formation and breakup of Pangaea. By the end of this lesson, you will be able to explain the concept of plate tectonics and describe the process of how the Earth's continents were once joined together as a single supercontinent.

## Section 1: Plate Tectonics
Plate tectonics is a theory that explains how the Earth's crust is broken up into several large pieces called plates. These plates move around on the surface of the Earth, and sometimes they collide with each other, causing earthquakes or volcanic eruptions. There are several types of plate boundaries, including convergent, divergent, and transform boundaries. At convergent boundaries, one plate slides under another, creating a subduction zone. At divergent boundaries, plates pull apart, creating a mid-ocean ridge. At transform boundaries, plates slide past each other horizontally.

## Section 2: The Formation of Pangaea
About 300 million years ago, all the Earth's continents were part of a single supercontinent called Pangaea. This name comes from the Ancient Greek words "pan" meaning "all" and "gaia" meaning "Earth." Over time, the continents began to drift apart due to movements in the Earth's crust. This process is called continental drift. As the continents moved away from each other, the oceans grew larger, and the climate changed. Eventually, Pangaea broke apart completely, leaving behind the seven continents we know today.

## Section 3: The Breakup of Pangaea
The breakup of Pangaea happened slowly over millions of years. It began when a giant supercontinent called Rodinia broke apart about 750 million years ago. Then, about 300 million years ago, Pangaea began to break apart. The first continent to split off was Gondwana, which eventually became Africa, South America, Antarctica, and Australia. Then, about 175 million years ago, North America and Europe began to separate. Finally, about 65 million years ago, the Pacific Plate began to move under the North American Plate, causing the subduction zone that created the Cascade Mountains.

## Section 4: Conclusion
In this lesson, we learned about plate tectonics and the supercontinent Pangaea. We learned that plate tectonics is the theory that explains how the Earth's crust is broken up into several large pieces that move around on the surface of the Earth. We also learned about the formation and breakup of Pangaea, and how this process shaped the Earth's continents into what they are today. By understanding these concepts, we can better understand the history of our planet and how it has evolved over time.

## Glossary
- Plate tectonics: The theory that explains how the Earth's crust is broken up into several large pieces called plates that move around on the surface of the Earth.
- Pangaea: A supercontinent that existed about 300 million years ago, made up of all the Earth's continents.
- Continental drift: The process by which the Earth's continents move apart from each other due to movements in the Earth's crust.
- Convergent boundary: A type of plate boundary where one plate slides under another, creating a subduction zone.
- Divergent boundary: A type of plate boundary where plates pull apart, creating a mid-ocean ridge.
- Transform boundary: A type of plate boundary where plates slide past each other horizontally.


text: Let’s face it, childbirth is quite painful and having an epidural for back pain can be effective in managing the pain. For many women, however, fear of having an epidural and concerns about the risks are just as intense as the fear of actually giving birth.. Understanding the basics of using an epidural for back pain in labor can help you decide if it is right for your delivery.. What is an epidural for back pain?. An epidural is an injection of medication into the epidural space to eliminate the sensations associated with childbirth. Instead of working systemically, throughout the entire body, an epidural only works on the nerves supplying the abdomen and lower body.

textbook:
Lesson: Epidurals for Back Pain During Childbirth

**Introduction**

In this lesson, we will learn about epidurals for back pain during childbirth. We will cover what an epidural is, how it works, and the benefits and risks associated with its use. By the end of this lesson, you will be able to make an informed decision about whether an epidural is right for you.

**Section 1: What is an Epidural?**

An epidural is a type of medication that is injected into the epidural space in a woman's lower back during childbirth. The epidural space is a small area between the spinal cord and the vertebrae. The medication is designed to numb the nerves that control sensation in the lower body, including the abdomen and legs. This means that when a woman receives an epidural, she will not feel pain in those areas.

**Section 2: How Does an Epidural Work?**

An epidural works by blocking the pain signals from reaching the brain. It does this by stopping the nerves from sending pain messages to the brain. The medication used in an epidural is a local anesthetic, which means that it only affects the area where it is injected. This allows the woman to remain awake and alert during childbirth, while still feeling minimal pain.

**Section 3: Benefits of Using an Epidural**

There are several benefits to using an epidural during childbirth. These include:

1. Reduced pain: The most obvious benefit of an epidural is that it significantly reduces the pain associated with childbirth. This can help a woman feel more comfortable and relaxed during the process.

2. Increased ability to focus: Because the woman is not focused on managing pain, she may be better able to concentrate on other aspects of her labor, such as breathing and relaxation techniques.

3. Improved ability to sleep: Many women report that they are able to sleep more easily during labor when they have an epidural. This can be helpful in allowing the woman to rest and conserve energy for the demands of childbirth.

**Section 4: Risks of Using an Epidural**

While there are several benefits to using an epidural, there are also some risks associated with this procedure. These include:

1. Low blood pressure: Some women may experience a drop in blood pressure after receiving an epidural. This can cause dizziness or fainting.

2. Slowed labor: In some cases, an epidural can slow down the progress of labor. This can result in longer labor or the need for additional interventions, such as a C-section.

3. Headaches: Some women may experience headaches after receiving an epidural. These headaches can be mild or severe and may last for several days after the birth.

**Section 5: Making the Decision**

Ultimately, the decision to use an epidural for back pain during childbirth is a personal one. It is important to consider the benefits and risks associated with this procedure and to discuss your options with your healthcare provider. Only you can decide what is best for your unique situation.

**Conclusion**

In this lesson, we have learned about epidurals for back pain during childbirth. We covered what an epidural is, how it works, and the benefits and risks associated with its use. By understanding these factors, you can make an informed decision about whether an epidural is right for you.

**Glossary**

- Epidural: A medication injected into the epidural space in a woman's lower back during childbirth to numb the nerves that control sensation in the lower body.
- Local anesthetic: A medication that numbs a specific area of the body without causing loss of consciousness.
- Vertebrae: The individual bones that make up the spine.

Growing your own fruit and nut trees is also good for the environment. Trees absorb carbon dioxide from the air and release oxygen, which helps to fight climate change. They also provide habitat for birds and other animals. By growing your own trees, you can reduce your carbon footprint and support wildlife.

## Section 2: Choosing the Right Trees for Your Area

Before you start planting trees, you need to choose the right ones for your area. Different trees are better suited for different climates and soil types. Here are some things to consider when choosing your trees:

### Topic 1: Climate

The climate in your area will affect which trees will grow best. For example, if you live in a cold area, you might want to choose trees that are hardy and can withstand freezing temperatures. If you live in a hot area, you might want to choose trees that can tolerate high heat.

### Topic 2: Soil Type

Different trees have different soil requirements. Some trees prefer well-drained soil, while others prefer wet or acidic soil. Make sure to choose trees that will thrive in your soil type.

### Topic 3: Space

You also need to consider the amount of space you have. Some trees can grow very tall and wide, while others are smaller and can be grown in containers or pots. Make sure to choose trees that will fit in the space you have available.

## Section 3: Caring for Your Trees

Once you have chosen the right trees for your area and soil type, you need to take good care of them. Here are some tips for caring for your fruit and nut trees:

### Topic 1: Watering

Trees need water to grow. Make sure to water your trees regularly, especially during dry spells. The amount of water they need will depend on the type of tree and the climate in your area.

### Topic 2: Pruning

Pruning is important for keeping your trees healthy and productive. Prune your trees in the winter, when they are dormant. Remove any dead or damaged branches, and thin out the branches to let more light in.

### Topic 3: Fertilizing

Trees need nutrients to grow. You can add compost or other organic matter to the soil around your trees to provide them with the nutrients they need. Make sure to follow the package instructions for the type and amount of fertilizer you are using.

## Conclusion

Growing your own fruit and nut trees is a fun and rewarding hobby that can save you money, help the environment, and provide you with delicious, healthy food. By choosing the right trees for your area and taking good care of them, you can enjoy a bountiful harvest for years to come.

Lesson Title: Data Sharing and Threads in Programming

Introduction:
Data sharing is an essential concept in programming that allows multiple threads to access and manipulate the same data. In this lesson, we will explore the different ways of sharing data between threads and the importance of using proper synchronization mechanisms to prevent race conditions.

Section 1: Multi-Process Shared Data and Thread Private Data
- Topic: Understanding the difference between multi-process shared data and thread private data.
- Question: What is the difference between multi-process shared data and thread private data?
- Answer: Multi-process shared data is data that can be accessed by multiple processes, while thread private data is data that is accessible only by the thread that created it.
- Example: In a multi-threaded program, if we want to create a variable that can be accessed by all threads, we should declare it as multi-process shared data. On the other hand, if we want to create a variable that can only be accessed by a specific thread, we should declare it as thread private data.
- Glossary: Multi-process shared data, Thread private data

Section 2: Confused about Type Checking
- Topic: Understanding the importance of type checking in programming.
- Question: Why is type checking important in programming?
- Answer: Type checking is important because it ensures that the data types used in a program are consistent and valid. This helps prevent errors and bugs in the program.
- Example: In Java, we can use the "instanceof" operator to perform type checking. For example, if we have an object "x", we can use "if (x instanceof Integer) { // do something }".
- Glossary: Type checking, Data types

Section 3: Confused about Data Sharing
- Topic: Understanding the different ways of sharing data between threads.
- Question: How can we share data between threads?
- Answer: We can share data between threads using three different mechanisms:
    - Synchronization: This involves using locks or mutexes to control access to shared data.
    - Message Passing: This involves sending messages between threads, which can contain data or pointers to data.
    - Shared Memory: This involves creating a single memory location that can be accessed by multiple threads.
- Example: In a program that uses multiple threads to process data, we can use message passing to send data between threads. Alternatively, we can use shared memory to create a single memory location that can be accessed by all threads.
- Glossary: Synchronization, Mutex, Message passing, Shared memory

Conclusion:
In this lesson, we explored the different ways of sharing data between threads and the importance of using proper synchronization mechanisms to prevent race conditions. We also learned about the different types of data sharing and the importance of type checking in programming. By understanding these concepts, we can write more efficient and robust programs that can handle multiple threads and large amounts of data.

Remember how amazing the graphics on some of these games were (or would have been) back in the 90’s? It’s funny how standards change so quickly. The technology does as well, of course, which makes possible the absurdly higher standards we have in the present. People could be impressed and games could be sold by such complex and groundbreaking features as enemies that could look in directions other than towards you. It seems terribly silly now but back then they were actually new and interesting features.

Of course, nowadays games that were sold on the appeal of the new technology of the 90’s alone don’t necessarily hold up. When a little adventure game called Myst came out in 1993, it was hailed as one of the best and most beautiful games on the market and helped push sales of then-new CD-ROM drives.

Will it hold up to modern criticism? Probably not, but let’s find out anyway.

SUMMARY

So you find a book and when you touch it you get pulled to a strange island known as Myst. Then you find some other books that have people trapped in them and they want you to let them out. But all is not as it seems. Also there are a lot of puzzles and very little in the way of help.

THE GOOD

If you ARE a puzzle person, then you will quickly find that the puzzles range from obscure to obtuse in their solutions and require all manner of exploration and experimentation and lateral thinking. This game can really strain your brain if you’re the kind who refuses to look at a guide – you actually need to think a little.

The story and background information is scattered throughout the world and the designers expect you to find it on your own – the game is full of books and cutscenes that you can skip through, but you need to have been paying attention to know what choice will lead you to the optimal ending.

The game makes effective use of background sound effects and music to really pull you into the locations you’re exploring.

Innovative and immersive first-person adventuring done well for the first time outside of a ‘dungeon crawler’.

You can’t die at any point until the very end, so you’re free to explore the world and experiment without penalty as much as you care to.

THE BAD

If you’re NOT a puzzle person, then you will quickly find that the puzzles range from obscure to obtuse in their solutions and require all manner of exploration and experimentation and lateral thinking. Except because you’re not a puzzle person you will not enjoy that at all and will quickly long for death.

The game does have a hint button, but it serves only to mock you and prolong your suffering.

You can’t die at any point until the very end, which if you don’t like puzzles means you are essentially trapped in your own very personal hell, progressing only in the pursuit of sweet, blessed release.

Myst more than any of its sequels just doesn’t hold up graphically – while you can tell it would have all been quite impressive in 1993, nowadays it’s obviously a series of low resolution slides and low resolution QuickTime movies.

THE VERDICT

Again, the games that came after it were far more refined and hold up better today. But if you can ignore dated graphics and you like getting lost in immersive, full-formed worlds, this game could end up being worth your time. This game was revolutionary when it came out, but you might want to try out one of the later games first (all of them are available on Steam) to see if you even like the style of gameplay it pioneered. 5/10

THE IN-DEPTH

Computers started as oversized calculators that used to fill whole rooms. I don’t think anyone ever envisioned at their inception that they would end up being used as portals to whole other worlds. I’m not talking about the ones they had hooked up to the Stargate, either, as I have recently been informed that Stargate is not actually a documentary.

Before Myst, games didn’t really try very hard to immerse you. Whether you made a character or were assigned one by the designers of the game, nobody put very much effort into keeping up the illusion that it was you who was there in the game experiencing the events first-hand. In Doom, your character wasn’t you, it was the stoic and possibly constipated space marine whose face adorned your status bar. In other games, like Monkey Island, you were placed in a third-person perspective and could see at all times that the character you were playing was clearly not you at all, and even if you tried to pretend otherwise you would know deep down inside of you that no matter how hard you lied to yourself you would never have adventures like that, and no matter how much you hoped to be taken into a world full of pirates and other things that are cool, you were still all alone, sitting at a desk in front of one of those harsh glowing screens that serve to this day as your only real friends.

Myst tried to change all that. It was one of the first games that actually put effort into letting you play you. The very few characters in the game addressed you directly, avoiding names or any details about your appearance, so that you could insert yourself into the formless void that was the protagonist. And apart from that you were alone, left to wander empty worlds solving puzzles to bring you closer to your goal.

And it worked, or it did back then. Part of it was the fact that, unlike other adventure games of the time, there was no secondary narration or accompanying text descriptions for anything you happened to see. You had to look at the world, examine the mechanisms and contraptions that made up the puzzles, and draw your own conclusions. You couldn’t just click ‘look at device’ and have a convenient popup tell you what its purpose was – you had to look at it and try to figure that out for yourself.

That contributed a lot – you had to think for yourself, the game told you you were playing as yourself, and so, if you didn’t think about it too hard, you did. You let yourself get lost in the world they had created and solve the puzzles the way you would, not the way an assigned character in the game world would.

It was a hell of an experience for 1993. And no, it doesn’t hold up anywhere near perfectly today. But it was a big step in the right direction, and as games become more and more focused on the immersion aspect, trying to pull us wholly into the worlds they create, it can be quite educational to go back and see where it began.

Of course, you could also play the sequels, Riven or Myst 3: Exile. They’re both on Steam, and they’re prettier, and they do most of the same things. But if you’re a real retro games enthusiast, this game is still worth a playthrough. Or at least a play-until-you-get-frustrated-and-delete-it.

TECHNICAL NOTES

I also didn’t end up having any trouble running Myst on my machine, but if you have trouble you can feel free to contact me and I’ll tell you what you should type into Google.

Lesson: Introduction to Cannabis Cultivation

## Section 1: Theoretical Concepts
Cannabis is a plant that has been cultivated for thousands of years for its medicinal, industrial, and recreational uses. In this lesson, we will learn about the basics of cannabis cultivation, including the different types of cannabis plants, their growth stages, and the factors that affect their growth.

**Types of Cannabis Plants:**
There are two main types of cannabis plants: **Sativa** and **Indica.** Sativa plants are tall and thin, with long, narrow leaves, while Indica plants are shorter and bushier, with wider leaves. The effects of these two types of plants are also different – Sativa plants tend to produce a more uplifting, cerebral high, while Indica plants produce a more body-focused, relaxing high.

**Growth Stages:**
Cannabis plants go through several growth stages before they are ready to be harvested. These stages include:

1. Germination: The seed sprouts and starts to grow.
2. Vegetative Stage: The plant grows leaves and stems, but does not produce flowers.
3. Flowering Stage: The plant produces flowers and begins to mature.
4. Harvest: The plant is ready to be cut down and dried.

**Factors Affecting Growth:**
Many factors can affect the growth of cannabis plants, including:

1. Light: Cannabis plants need at least 18 hours of light per day to grow properly.
2. Temperature: The ideal temperature for cannabis plants is between 70-80°F (21-27°C).
3. Nutrients: Cannabis plants need nutrients like nitrogen, phosphorus, and potassium to grow properly.
4. Water: Cannabis plants need water to stay hydrated and healthy.
5. Soil: The type of soil used can affect the quality and taste of the final product.

## Section 2: Practical Examples
Now that we know some of the basics of cannabis cultivation, let's look at some practical examples of how to grow cannabis.

**Growing Cannabis Indoors:**
If you live in an area where cannabis cultivation is legal, you can grow cannabis indoors using specialized equipment like grow lights, ventilation systems, and hydroponics setups. Here are some steps to follow:

1. Choose a location with enough space for your plants to grow.
2. Set up your grow lights to provide at least 18 hours of light per day.
3. Use a hydroponics system or soil to provide nutrients to your plants.
4. Monitor the temperature and humidity levels in your growing area.
5. Harvest your plants when the buds are fully developed and the leaves have turned brown.

**Growing Cannabis Outdoors:**
If you live in an area where cannabis cultivation is legal and you have a backyard or other outdoor space, you can grow cannabis outdoors. Here are some steps to follow:

1. Choose a sunny location with good drainage.
2. Plant your seeds in the soil and water them regularly.
3. Monitor the plants for pests and diseases.
4. Harvest the plants when the buds are fully developed and the leaves have turned brown.

## Section 3: Self-Debating Discussions
In this section, we will engage in self-debating discussions to teach critical thinking.

**Debate: Should Cannabis Cultivation Be Legal?**
Some people argue that cannabis cultivation should be legal because it has many medicinal benefits, while others argue that it should remain illegal because it can be addictive and lead to social problems. What do you think?

## Conclusion
In this lesson, we learned about the basics of cannabis cultivation, including the different types of cannabis plants, their growth stages, and the factors that affect their growth. We also looked at practical examples of how to grow cannabis indoors and outdoors. Finally, we engaged in self-debating discussions to teach critical thinking. By applying the skills we learned in this lesson, we can grow our own cannabis and understand the complexities of this fascinating plant.

Lesson: How to Compare Prices and Saves Money

Introduction:
In today's world, we often need to compare prices and make informed decisions about our purchases. This lesson will teach you how to compare prices and save money. We will cover the following topics:

1. Understanding the concept of regular price and sale price
2. Calculating discounts and savings
3. Reading and interpreting price comparison charts
4. Applying these skills to real-life scenarios

Section 1: Understanding the Concept of Regular Price and Sale Price

**Topic 1: Regular Price**
The regular price of an item is the original price set by the seller. It is also known as the full price or list price.

**Topic 2: Sale Price**
The sale price is the reduced price of an item. It is usually lower than the regular price and is offered during special promotions or events.

**Topic 3: Discount**
A discount is the difference between the regular price and the sale price. It is usually expressed as a percentage of the regular price.

**Topic 4: Savings**
Savings is the amount of money you save by buying an item on sale instead of at its regular price.

Section 2: Calculating Discounts and Savings

**Topic 1: Calculating Discounts**
To calculate the discount, you can use the following formula:

Discount = (Sale Price - Regular Price) / Regular Price

For example, if the regular price of an item is $50 and the sale price is $40, the discount would be:

Discount = ($40 - $50) / $50 = 0.2 or 20%

**Topic 2: Calculating Savings**
To calculate the savings, you can use the following formula:

Savings = Regular Price - Sale Price

For example, if the regular price of an item is $50 and the sale price is $40, the savings would be:

Savings = $50 - $40 = $10

Section 3: Reading and Interpreting Price Comparison Charts

**Topic 1: Understanding Price Comparison Charts**
Price comparison charts are used to compare the regular price and sale price of two or more items. They usually show the original price, sale price, discount, and savings for each item.

**Topic 2: Interpreting Price Comparison Charts**
To interpret a price comparison chart, follow these steps:

1. Identify the regular price and sale price of each item.
2. Calculate the discount for each item.
3. Determine the savings for each item.
4. Compare the items based on their regular price, sale price, discount, and savings.

Section 4: Applying These Skills to Real-Life Scenarios

**Topic 1: Shopping Smart**
When shopping, always check for sales and discounts before making a purchase. Compare the regular price and sale price of the item to ensure that you are getting the best deal.

**Topic 2: Comparing Prices Online**
When shopping online, use price comparison websites to find the best deals. Make sure to check the regular price, sale price, shipping costs, and return policies before making a purchase.

**Topic 3: Saving Money**
By comparing prices and waiting for sales, you can save a significant amount of money on your purchases. Use these skills to make informed decisions about your spending and watch your savings grow.

Glossary:
- Regular price: The original price set by the seller
- Sale price: The reduced price of an item
- Discount: The difference between the regular price and the sale price
- Savings: The amount of money you save by buying an item on sale

Conclusion:
By learning how to compare prices and save money, you can make informed decisions about your purchases and save money in the process. These skills are essential for smart shopping and managing your finances. Apply these skills to new situations and watch your savings grow.

# Lesson 1: Introduction to Video Reviews
In this lesson, we will learn about video reviews and how they can be used to analyze and critique films and television shows. We will cover the following topics:

## Topic 1: What is a Video Review?
A video review is a form of media criticism where a person records a video of themselves talking about a film or television show. In this video, they share their thoughts and opinions on the quality of the production, acting, storyline, and other elements that make up the final product. Video reviews are popular among audiences who want to hear the opinions of others before deciding whether or not to watch a particular movie or TV show.

## Topic 2: How to Create a Video Review
To create a video review, follow these steps:

1. Choose a film or television show you want to review.
2. Watch the entire production before recording your video review.
3. Prepare a script or outline of what you want to say in your review.
4. Record your video review using a camera or smartphone.
5. Edit your video review to remove any mistakes or awkward pauses.
6. Publish your video review on a platform such as YouTube or Vimeo.

## Topic 3: Types of Video Reviews
There are several types of video reviews, including:

1. Field of the Invention
This invention relates to strategic and/or educational games and, more particularly, to strategic and/or educational games played on a board around which tokens are placed and moves are directed by players based on the use designating device such as a spinner.
2. Description of the Related Art
There are large numbers of strategic and/or educational board games on the market today. Each game offers its own unique strategies and/or teaches users certain things in a unique way. One example of a known board game is found in U.S. Pat. No. 3,170,696 to Nielsen. In the game of Nielsen, each player has an assigned row (e.g., in a four-person version there are four parallel rows, each of a different color, with each player being assigned a different row/color), and the player uses his or her assigned row as his or her field of play during the game. Chips are moved around the field of play, with movement of chips by a particular player being restricted to their own field of play. The game ends when one of the players has moved their chips in such a manner that they have filled their “home bonus member” with chips.
It is an object of the present invention to improve upon existing strategy and/or educational games by creating a strategy/educational board game with a unique field of play and set of rules that improves counting skills, matching skills, and strategic thinking skills.

This situation led to the following thought: my experience is that you have to be at a conference or meeting to really get the central thoughts, the feeling the people are trying to get across. Nothing can substitute human interaction. But in this era of podcasts ((live) video and audio), broadcasting via the web, it does give you the opportunity to rethink whether you really should go to the conference (all the way in the USA...), because you can (practically) relive the conference via the internet. Does this lead to less conference visitors? I hope not.

Linda Stone is an interesting person with interesting ideas. She coined the term 'continuous partial attention'. This is not the same as multitasking. But it's "an adaptive behavior that presumably allows us to keep pace with the never-ending bandwidth technology offers." She also signals more and more people that protest against the tyranny of tantalizing choices. (Relates well with Barry Schwarz's, "Less is more"!) I just read she is listed nr. 7 on the HBR list of Breakthrough ideas 2007!We have come from information scarcity (pull) and are now loaded with information (push). The next step seems to be how we can get away from all the impulses, information, devices that bug us and make us feel miserable. Although I don't feel miserable yet I am very happy with technology such as RSS and social tagging that help you get the (new) information you want, find and remember paths through information and leave out all the rest. Stone predicts that p…

A couple of days ago IBM annouced their new collaboration suite: IBM Connections. It's planned to be shipped in the first quarter of 2007. What's in it?"The IBM package includes five applications: profiles, where employees post information about their expertise and interests; communities, which are formed and managed by people with common interests; activities, which are used to manage group projects; bookmarks, where people share documents and Web sites with others; and blogs, where people post ongoing commentaries. "The business market is showing a lot of interest in using social networking tools to improve productivity. It's about helping people find experts and the information they need to get their jobs done," says Steve Mills, the general manager of the software group at IBM (IBM). The commercial version of the package is to be delivered in the second quarter.(...)During an IBM demonstration of Lotus Connections, it was clear that the product is easy t…

Not to long ago I started using Trailfire. Trailfire is a wonderful way to add annotations to webpages you look at regularly or run into. It allows you to give your context to webpages and helps you remember where you were browsing and what you were thinking when you read that page. It also helps you connect related pages together (you can flip between annotations). You can keep the trails to yourself and/or share them with other (even if they done have Trailfire).But this is also very interesting for in the enterprise! For instance when your team is looking for and collecting information on a certain topic. Leaving trails can also help new employees move through the large amount of information he/she has to go through and help him/her find the really important information he/she may not miss. The names of annotators helps them find the right people in the organisation to talk to.You could even have a trail that starts inside the organisation and moves outside. Even if that trail is p…

I love Google and use many of their products/services (Gmail, Reader, Blogger, Docs and Spreadsheets, Alerts, Maps, Desktop, Picasa, etc.). These tools compete directly with products as Outlook, Word, Excel, etc.Although Google products are free and can also be used in enterprises, I haven't heard of many companies dumping Microsoft and using free web 2.0 stuff (from Google a.o.) from then on.Anyway, I was wondering what Google's information architecture looks like. Of course reports, memo's, minutes, etc. are written at Google. Where do they store them? How do they share and distribute them? Do they have policies where Google employees should save their (draft) documents and which tools they should use to produce information? Do they have a knowledge manager or information architect? And how does he/she work?

I sent these questions to Google and hope to get some answers that I can share with you. I think it would be neat to know how they do it and why. Possibly inspiring t…

There's a new book out by Ichijo & Nonaka (- you know, from "The Knowledge Creating Company", written with Takeuchi). It's titled: "Knowledge Creation and Management: New Challenges for Managers" (2007).

Looks very interesting! It's not only written by them, but lots of great Knowledge Management thinkers have been asked to write one or more chapters. I ordered it and hope to read it soon and let you know what I think of it.

Just started this blog! And I'm excited about it. This blog will be about my job as an information architect for a fairly large company called Océ. I'm not going to use this blog to tell you all the ins and outs of Océ (even if I was allowed to). But I want to give you my view on this very interesting topic and the just as interesting related topics. My role is to support document, information and knowledge processes in such a way that business processes are improved. My interests are therefore in information architecture in general, and specifically in information architecture methodology. Furthermore I like to read and learn about implementing document management systems, collaboration, web 2.0 (enterprise 2.0), knowledge management in general, etc.

Hope you enjoy reading my blog and I hope you will share your insights with me too!

Lesson: The Importance of Attending Conferences in the Age of Technology

Introduction:
Conferences are an essential part of learning, networking, and sharing knowledge in various fields. However, with the advent of technology, it is possible to attend conferences virtually without physically being there. In this lesson, we will explore the importance of attending conferences even in the age of technology, the concept of continuous partial attention, and the dangers of multitasking.

Section 1: The Importance of Attending Conferences

Topic 1: The Benefits of Attending Conferences
- Physical conferences provide opportunities for face-to-face interactions, which are essential for building relationships and networking.
- Conferences provide a platform for learning from experts in the field and staying updated on the latest research and developments.
- Conferences offer a chance to present your work, receive feedback, and collaborate with others in your field.

Topic 2: The Value of Physical Presence at Conferences
- Physical presence at conferences allows for spontaneous interactions and conversations that can lead to new ideas and collaborations.
- Attending conferences in person demonstrates commitment to the field and can open doors for future opportunities.
- Physical attendance at conferences allows for better engagement and retention of information, as well as the ability to ask questions and participate in discussions.

Section 2: Continuous Partial Attention and Multitasking

Topic 1: The Difference Between Continuous Partial Attention and Multitasking
- Continuous partial attention refers to the ability to pay attention to multiple stimuli simultaneously, while multitasking refers to switching between tasks quickly.
- Continuous partial attention allows for better information processing and retention, while multitasking can lead to cognitive overload and decreased productivity.
- Continuous partial attention requires focus and discipline, while multitasking often involves distraction and impulsivity.

Topic 2: The Dangers of Multitasking
- Multitasking can lead to decreased performance and increased errors, as the brain struggles to switch between tasks quickly.
- Multitasking can also result in shallow processing of information, leading to poor comprehension and retention of knowledge.
- Constant interruptions and distractions can cause stress and anxiety, negatively impacting mental health and well-being.

Section 3: The Future of Conferences in the Age of Technology

Topic 1: The Advantages of Virtual Conferences
- Virtual conferences offer increased accessibility and affordability, allowing more people to participate in events.
- Virtual conferences provide opportunities for attendees to interact with speakers and other participants, leading to better engagement and retention of information.
- Virtual conferences can be recorded and accessed later, providing a valuable resource for learning and reference.

Topic 2: The Disadvantages of Virtual Conferences
- Virtual conferences lack the personal touch and networking opportunities available at physical conferences.
- Virtual conferences can lead to decreased motivation and engagement, as attendees may struggle to stay focused and committed.
- Virtual conferences may not provide the same level of interaction and collaboration as physical conferences, leading to decreased creativity and innovation.

Conclusion:
In conclusion, attending conferences, even in the age of technology, remains an essential part of learning, networking, and sharing knowledge. While virtual conferences offer advantages such as increased accessibility and affordability, physical conferences provide opportunities for personal interaction, networking, and collaboration. It is crucial to balance the use of technology with the benefits of physical attendance at conferences, while practicing continuous partial attention and avoiding multitasking. By doing so, we can maximize our potential for learning, growth, and success in our respective fields.

Glossary:
- Conference: A meeting or event where people in a particular field come together to share knowledge, learn from each other, and network.
- Continuous partial attention: The ability to pay attention to multiple stimuli simultaneously, while still maintaining focus and discipline.
- Multitasking: Switching between tasks quickly, often involving distraction and impulsivity.
- Virtual conference: A conference that takes place online, allowing participants to interact with speakers and other attendees virtually.

[The radioactive antiglobulin (Coombs') test].
Weak red cell sensitization by hemolyzing antibodies may not be detected by the standard antiglobulin test. For the diagnosis of certain immune hemolytic anemias more sensitive methods are needed. Anti-IgG was purified as F(ab)2 by pepsin digestion and labelled with 125 I using the chloramine T method. 15 X 10(7) cells were washed and suspended in 0.1 ml of 6% albumin in saline. After incubation with 0.1 ml of 125 I-anti-IgG F(ab')2 for 30 minutes, the cells were washed and the uptake of radioactivity was counted using a gamma-counter. Standard cells were coated with a known concentration of an IgG anti-D preparation in the range of 50--1000 molecules per red cell. The sensitivity for the detection of red cell sensitization was at least 50 molecules per red cell. Because of varying binding ratios between the labelled anti-IgG reagent and different red cell antibodies the determination of the exact number of IgG molecules on the red cells is difficult. However, this very sensitive and reproducible method shows practical advantages in comparison with a complement fixation antibody consumption method with which corresponding results were obtained. Beside the evaluation of antiglobulin test negative autoimmune hemolytic anemias, this method may be applied for the determination of the specificity of weak red cell alloantibodies not detectable by standard blood bank procedures.

Lesson: Introduction to Radioactivity

### Overview
In this self-taught lesson, we will explore the concept of radioactivity, which is the emission of particles or energy from the nucleus of an atom. We will cover the basics of radioactivity, including what it is, how it occurs, and its applications in various fields.

### Section 1: What is Radioactivity?
Radioactivity is the spontaneous emission of particles or energy from the nucleus of an atom. This process occurs when the nucleus of an unstable atom undergoes a change, releasing particles or energy in the form of electromagnetic radiation.

### Section 2: Types of Radioactivity
There are two main types of radioactivity: alpha and beta decay. Alpha decay occurs when an unstable nucleus emits an alpha particle, which consists of two protons and two neutrons. Beta decay occurs when an unstable nucleus emits a beta particle, which is an electron. Both types of decay result in the formation of a new, more stable nucleus.

### Section 3: Applications of Radioactivity
Radioactivity has many applications in various fields, including medicine, industry, and research. In medicine, radioactive substances are used to treat cancer and other diseases. In industry, radioactivity is used to detect flaws in materials and to measure the age of fossils. In research, radioactive substances are used to study the behavior of atoms and subatomic particles.

### Section 4: Conclusion
In conclusion, radioactivity is a fascinating and useful phenomenon that has many practical applications in various fields. By understanding the basics of radioactivity, we can appreciate its importance and potential in our daily lives.
