Goldstein, David B.

David B. Goldstein is a director of the energy program of the Natural Resources Defense Council. He has worked on energy efficiency and energy policy since the 1970s. He has been instrumental in the development of energy efficiency standards for new buildings and appliances currently in effect at the regional and national level in the United States, Russia, Kazakhstan, and China. Dr. Goldstein received a Ph.D. in Physics from the University of California at Berkeley, is a Fellow of the American Physical Society and the recipient of its Leo Szilard Award for Physics in the Public Interest. He received a MacArthur Fellowship in 2002.

Every few years, a new report emerges that tries to resurrect an old hypothesis: that energy efficiency policy somehow results in consumers using more energy instead of less. This hypothesis was introduced in the 19th Century by economist William Stanley Jevons, who argued that increases in the energy efficiency throughout a nation would lead to increases in coal consumption, rather than decreases.

Recent articles have attempted to revive these claims, also known as “rebound effect” —restating that energy efficiency tends to encourage more energy use, not less, and that if a consumer’s immediate goal is to tackle climate change, then it seems risky to count on reaching it by improving efficiency. Assuming rebound effects eat up most of the energy savings, such claims then argue that efficiency cannot be a good policy to reduce energy consumption or combat climate change.

Title: The Myth of the Rebound Effect: How Energy Efficiency Saves Energy and Money

Abstract:
Energy efficiency has been proven to be one of the most effective ways to reduce energy consumption and greenhouse gas emissions. However, there is a persistent myth that energy efficiency leads to a "rebound effect," where increased efficiency causes people to use more energy, negating the benefits. This myth has been discredited by numerous studies, but it continues to be repeated in the media and by some policymakers. In this lesson, we will explore the science behind energy efficiency and debunk the rebound effect myth.

Section 1: Introduction to Energy Efficiency
- Energy efficiency refers to using less energy to perform the same tasks, such as lighting, heating, and cooling.
- Improving energy efficiency can save money on energy bills and reduce greenhouse gas emissions.
- Energy efficiency is not just about using more efficient appliances; it also involves changing behaviors and practices.

Section 2: The Rebound Effect Myth
- The rebound effect myth suggests that increased energy efficiency leads to people using more energy, negating the benefits of efficiency.
- This myth was first proposed by economist William Stanley Jevons in the 19th century, who believed that increased efficiency would lead to increased coal consumption.
- However, numerous studies have debunked this myth and shown that energy efficiency actually leads to reduced energy consumption and emissions.
- One study found that energy efficiency measures in the United States between 1970 and 2000 resulted in energy savings equivalent to the entire energy consumption of China in 2000.

Section 3: Why Energy Efficiency Works
- Energy efficiency works because it changes the way people think about energy use.
- When people understand the benefits of energy efficiency, they are more likely to make changes in their behavior and practices.
- For example, when people learn about the benefits of energy-efficient light bulbs, they are more likely to switch to them, leading to reduced energy consumption.
- Similarly, when buildings are designed with energy efficiency in mind, occupants are more likely to use less energy without even realizing it.

Section 4: Real-World Examples of Energy Efficiency
- Many countries have implemented successful energy efficiency policies, such as the United States' Energy Star program.
- The European Union has set a goal of achieving a 20% reduction in energy consumption by 2020 through energy efficiency measures.
- China has implemented a building energy efficiency labeling system, which has led to significant reductions in energy consumption.

Section 5: Conclusion
- Energy efficiency is a powerful tool for reducing energy consumption and emissions.
- The rebound effect myth has been debunked by numerous studies and does not hold up to scientific scrutiny.
- By understanding the benefits of energy efficiency and implementing policies that encourage its adoption, we can save money on energy bills and reduce our impact on the environment.

Glossary:
- Energy efficiency: the use of less energy to perform the same tasks.
- Rebound effect: the myth that increased energy efficiency leads to increased energy consumption.
- Greenhouse gas emissions: gases in the atmosphere that trap heat and contribute to climate change.

Conclusion:
By understanding the science behind energy efficiency and debunking the rebound effect myth, we can see that energy efficiency is a powerful tool for reducing energy consumption and emissions. By implementing policies that encourage its adoption, we can save money on energy bills and reduce our impact on the environment.

Lesson: Designing a Garden Layout

Introduction:
Gardening is an enjoyable and rewarding hobby that allows you to connect with nature and create beautiful spaces. However, designing a garden layout can be daunting for beginners. In this lesson, we will learn about the key principles of garden design and how to apply them to create a functional and aesthetically pleasing garden.

Section 1: Understanding Garden Design Principles

Topic 1: Balance
Balance is one of the essential principles of garden design. It refers to the distribution of elements within the garden, ensuring that no one area dominates the others. To achieve balance, you can use repeating shapes, colors, and textures throughout the garden.

Topic 2: Proportion
Proportion is another crucial principle of garden design. It involves arranging elements in a way that creates a harmonious relationship between them. For example, you can use tall plants to create vertical interest or place a large rock in the center of a circular bed to create a focal point.

Topic 3: Harmony
Harmony is the third principle of garden design, which involves creating a sense of unity and cohesiveness within the space. You can achieve harmony by using similar colors, textures, and forms throughout the garden.

Section 2: Applying Garden Design Principles

Topic 1: Creating Garden Structure
Creating a garden structure is essential for defining the space and making it look more organized. You can use hardscaping elements such as paths, walls, and fountains to create a sense of order within the garden.

Topic 2: Using Plant Materials Effectively
Plant materials are the backbone of any garden. They provide color, texture, and form. To use them effectively, you should consider their growth habits, light requirements, and water needs. You can also group plants with similar needs together to make maintenance easier.

Topic 3: Creating Garden Rooms
Garden rooms are small, defined spaces within the garden that have a specific focus. You can create these rooms by using plants, hardscaping elements, or both. For example, you could create a seating area with a bench and surrounding plants or a vegetable garden with raised beds and trellises.

Section 3: Practical Examples

Example 1: A Small Front Yard Garden
In a small front yard garden, you can create a sense of balance by using symmetrical plantings around the entrance. To achieve proportion, you can use taller plants at the corners of the yard and shorter plants in the center. Finally, to create harmony, you can use similar colors and textures throughout the garden.

Example 2: A Large Backyard Garden
In a large backyard garden, you can create structure by using a central pathway that leads to a seating area. You can use tall shrubs or trees to frame the space and create a sense of enclosure. To use plant materials effectively, you can group plants with similar needs together and use them to create visual interest.

Conclusion:
Designing a garden layout is an art that requires creativity, attention to detail, and a good understanding of garden design principles. By applying balance, proportion, and harmony, you can create a functional and aesthetically pleasing space that reflects your personal style. Remember to experiment with different elements and styles to find what works best for you. With practice, you'll soon be creating stunning gardens that bring joy to yourself and others.

Glossary:
- Balance: The distribution of elements within the garden, ensuring no one area dominates the others.

text: My very first Southern art experience was with 75 artists cranking out drawings in one room at the High Museum of Art, Saturday September, 12, 2015.. Every hour for 3 hours, 25 artists draw while the DJ plays great beats. Attendants whisked away our drawings to a photographer and then to the sale area where they were sold to the first bidder for $75. Each piece was created to support the museum and artists they represent. With a purchase of a drawing you received a bag with all of the artists' names.. A very unique and extremely enjoyable experience! A huge thanks are in order to the museum staff and Curator Michael Rooks.

Art has the power to inspire and challenge us, and to raise awareness about important social issues. By supporting local artists, we are helping to create a more informed and engaged society that values creativity and innovation.

Section 2: How to Support Local Artists

Topic 1: Buying Art
One of the best ways to support local artists is by buying their work. This can be done by attending art fairs, visiting galleries, or purchasing art online. When buying art, it is important to consider the price, quality, and authenticity of the work. It is also important to remember that not all artists are famous or wealthy, so it is important to treat them with respect and appreciation.

Topic 2: Sharing Art
Another way to support local artists is by sharing their work with others. This can be done by posting pictures of their art on social media, writing reviews, or recommending their work to others. By sharing art, we can help to increase its visibility and reach a wider audience.

Topic 3: Volunteering
Volunteering is another way to support local artists. Many artists rely on volunteers to help them with tasks such as promoting their work, selling tickets, or manning booths at art fairs. By volunteering, we can help to reduce the costs associated with running an art business and allow artists to focus more on their creative work.

Section 3: Real-World Examples

Example 1: The High Museum of Art
The High Museum of Art is a nonprofit organization that supports the arts in Atlanta, Georgia. They host events such as the Southern Art Experience, which brings together 75 artists to create drawings that are sold to the first bidder for $75 each. All proceeds go towards supporting the museum and the artists they represent.

Example 2: The Artist's Way
The Artist's Way is a book by Julia Cameron that teaches people how to unlock their creative potential. One of the exercises in the book involves writing three pages of stream-of-consciousness writing every day. This exercise helps to break down creative blocks and allows artists to access their inner creativity.

Conclusion:
In conclusion, supporting local artists is important because it helps to create jobs, stimulate economic growth, and enrich our culture. There are many ways to support local artists, including buying their work, sharing their art, and volunteering. By doing so, we can help to create a more vibrant and engaged society that values creativity and innovation.

International humanitarian organizations typically operate in areas where there is a need for aid and assistance. They work with local partners and communities to identify the most pressing needs and develop programs to address them. These organizations also work to raise awareness about the issues affecting people in need and advocate for policies that will help improve their lives.

**Section 2: The Importance of Independence and Risk-Taking in International Humanitarian Organizations**

**Topic 4: Why is independence important for international humanitarian organizations?**
Independence is critical for international humanitarian organizations because it allows them to operate freely and impartially in areas affected by crises. When organizations are not beholden to any one government or interest group, they can provide aid and assistance based on need alone.

**Topic 5: Why is taking risks important for international humanitarian organizations?**
Taking risks is important for international humanitarian organizations because it allows them to reach people in need who may be in dangerous or difficult-to-reach areas. By taking risks, these organizations can provide aid and assistance to those who need it most, even if it means putting themselves in danger.

**Section 3: The Importance of Localization in International Humanitarian Organizations**

**Topic 6: What is localization in the context of international humanitarian organizations?**
Localization refers to the process of transferring responsibility for providing aid and assistance to local organizations and communities. This approach is becoming increasingly popular among international humanitarian organizations because it allows them to work more closely with local partners and communities, which can lead to more effective and sustainable programs.

**Topic 7: Why is localization important for international humanitarian organizations?**
Localization is important for international humanitarian organizations because it allows them to build stronger relationships with local partners and communities. By working more closely with local organizations and individuals, these organizations can better understand the needs and priorities of the people they are trying to help. In addition, localization can help reduce the dependence of local communities on external aid, which can lead to more sustainable and long-term solutions.

**Conclusion:** Through this lesson, we have learned about the role and function of international humanitarian organizations, the importance of independence and risk-taking, and the benefits of localization. We have also explored how these organizations operate and the types of aid they provide. As we continue to learn about the world around us, it is important to remember the critical role that international humanitarian organizations play in improving the lives of people in need. By understanding their work and supporting their efforts, we can help make a difference in the world.

text: Pay Attention. Stay Focused: We think much faster than we speak. As a result, our brains may use the ‘spare time’ to think of what we are going to say next. In the process, we may miss important information.. Sometimes we are ‘hearing’ but not ‘listening’, for example pretending to be attentive but thinking about what to do this weekend. This often happens unconsciously, however it can lead to missing important information and may be perceived as disrespectful.. Avoid Distractions: Try to focus with both ears on each word being communicated.. Listen for meaning and not just words: Listen to the tone the customer is using and how they respond, to better understand the meaning of what is being communicated.

Lesson: Introduction to Dictionaries

**Lesson Overview:** In this lesson, we will learn about dictionaries and how they can help us understand the meaning of words. We will explore different types of dictionaries and discover the importance of using them when reading or writing.

**Objective:** By the end of this lesson, students will be able to:

- Define what a dictionary is and its purpose
- Identify the different types of dictionaries
- Use a dictionary to find the meaning of a word
- Explain the importance of using a dictionary when reading or writing

**Section 1: What is a Dictionary?**

A dictionary is a collection of words and their meanings. It is a tool that helps people understand the meaning of words they may not know. Dictionaries come in many forms, including paper, online, and even audio versions.

**Section 2: Types of Dictionaries**

There are several types of dictionaries, each with its own purpose. Some common types include:

1. Monolingual dictionaries: These are dictionaries that contain words and their meanings in one language only. An example is the Schofield and Sims Picture Dictionary, which is a monolingual dictionary for young children learning English.

2. Bilingual dictionaries: These are dictionaries that contain words and their meanings in two languages. They are useful for people who are learning a second language.

3. Bilingual visual dictionaries: These are like bilingual dictionaries but use pictures instead of words to show the meaning of a word.

4. Thesauri: These are dictionaries that contain words that are related to each other in some way, such as meaning or usage.

Lesson: How to Read and Interpret Graphs and Charts

**Introduction:**

In today's world, data is presented in various forms such as graphs, charts, and tables. Being able to read and interpret this information is essential for making informed decisions. In this lesson, we will learn how to read and interpret graphs and charts.

**Section 1: Understanding Graphs and Charts**

A graph is a visual representation of data that uses points, lines, or bars to show the relationship between different categories of information. A chart, on the other hand, is a type of graph that uses symbols to represent data. Both graphs and charts can be used to display various types of data, including numerical, categorical, and time-series data.

**Section 2: Reading and Interpreting Graphs and Charts**

To read and interpret graphs and charts, you need to follow these steps:

1. Identify the title and axis labels. These provide information about the data being displayed.
2. Look at the scale of the graph or chart. This will help you understand the magnitude of the changes being represented.
3. Examine the data points or bars. These represent specific pieces of information and are usually labeled with a number or category.
4. Analyze the trends and patterns in the data. This will help you understand the overall message of the graph or chart.
5. Compare the data to other sources or information to validate its accuracy and relevance.

**Section 3: Practical Examples**

Let's look at an example of a graph and chart to see how we can apply these steps:

Graph: The graph below shows the population of a city over time.

```

Q:

When galaxies collide, what happens to dark vs. light matter?

I have read that galactic collisions have been used as evidence demonstrating the effects of dark matter. In particular, that luminous matter slows down and interacts while dark matter shoots through, essentially unopposed.
If a typical galaxy consists of a particular ratio of dark and light matter (or range of ratios, I guess), would a collision remnant contain less, or even zero, dark matter? Do we see regions of gravitational lensing with a lower-than-expected luminous matter component that could be remnants from significant collisions?

A:

This is exactly what occurred in the collision in a galaxy cluster known as the Bullet Cluster. The name comes from the red shock wave to the right of the picture, indicating a collision in the past.

In this picture, created in 2003, two galaxy clusters have collided and passed through each other. The red coloring indicates where X-rays from high-temperature hydrogen gas were detected by the Chandra X-ray Observatory. Most of the normal (baryonic) matter in a galaxy cluster is in this hydrogen gas, not the stars, black holes, and other visible objects. So, the red is where most of the normal matter is located. The hot gases from the two galaxies interacted electromagnetically and clumped together in the middle of the collision point. Electromagnetic interactions often result in photons being released, carrying away energy and allowing the normal matter to clump together (not too dissimilar from photons emitted when electrons bond to nuclei).
The blue indicates where most of all the mass is, as inferred from weak gravitational lensing--that is, the distortion of images of galaxies (taken by the Hubble Telescope) from behind this cluster due to the gravity of these galaxies. The lensing is weak in this picture, so it's difficult to see, but a more obvious example can be seen in the following picture of a galaxy. The central reddish-yellow galaxy is distorting the image of the blue galaxy directly behind it.

So, going back to the first picture, the majority of the mass that gravitates (the blue) can be separated from the mass that interacts with light (the red). The conclusion to draw is that most of the matter in a galaxy is made up of something that does not give off light (hence, dark) but still gravitates. Dark matter only seems to interact with anything (even itself) via gravity, so it doesn't clump like normal matter can. During and after the collision, it seems that dark matter just passed right on through, thus becoming separated from the normal matter. Note that the actual galaxies of the two clusters (which contain a small fraction of the total normal matter) are also visible as two clusters located at the same place as the inferred gravitating mass (blue). This is because, like the dark matter, galaxies are collisionless (stars are too sparse to collide).
Here's another collision with similar results found in 2008. The colors indicate the same measurements as the Bullet Cluster (blue is where gravity is generated, red is where the normal matter is).

Postscript to actually answer the question: We have found galaxies that are almost entirely dark matter (Dragonfly 44) and ones that have almost no dark matter (NGC-1052-DF2) However, it is unknown how these galaxies came to be like that or whether collisions were involved. As for the Bullet Cluster, I think you are right. In billions of years, there will be two galaxy clusters speeding away from each other with less luminous matter than expected and a gradually cooling mass of gas in-between.

Update:
A new studies of NGC-1052-DF2, the purported galaxy with no dark matter, find that the measured distance was incorrect. Correcting this distance results in new calculations showing the galaxy has a normal amount of dark matter.

Lesson: The Effect of Galaxy Collisions on Dark Matter

Introduction:
Galaxy collisions are events in which two or more galaxies come into contact with each other. These collisions can have a significant impact on the distribution of dark and light matter within the galaxies involved. In this lesson, we will explore the effect of galaxy collisions on dark and light matter.

Section 1: The Nature of Dark and Light Matter
Dark matter is a form of matter that does not interact with light or other forms of electromagnetic radiation. It is estimated to make up about 27% of the total mass-energy content of the universe. On the other hand, light matter is the ordinary matter that we are familiar with, such as stars, planets, and gas. It makes up about 5% of the total mass-energy content of the universe.

Section 2: The Effect of Galaxy Collisions on Dark Matter
When galaxies collide, the luminous matter (i.e., stars, gas, and dust) slows down and interacts, while dark matter shoots through essentially unopposed. This phenomenon has been used as evidence demonstrating the effects of dark matter. In particular, it has been observed that during a galaxy collision, the luminous matter slows down and interacts while dark matter shoots through, essentially unopposed.

Section 3: The Bullet Cluster
The Bullet Cluster is a galaxy cluster that has provided strong evidence for the existence of dark matter. The name comes from the red shock wave to the right of the picture, indicating a collision in the past. In this picture, created in 2003, two galaxy clusters have collided and passed through each other. The red coloring indicates where X-rays from high-temperature hydrogen gas were detected.

The Bullet Cluster provides evidence for the existence of dark matter because the distribution of dark matter can be inferred from the motion of the galaxies within the cluster. The dark matter does not appear to be slowed down by the collision, as the luminous matter is. Instead, it continues to move at high speeds, indicating that it is not affected by the collision in the same way that luminous matter is.

Section 4: Conclusion
In conclusion, galaxy collisions have a significant impact on the distribution of dark and light matter. During a collision, the luminous matter slows down and interacts while dark matter shoots through, essentially unopposed. The Bullet Cluster provides strong evidence for the existence of dark matter, as the distribution of dark matter can be inferred from the motion of the galaxies within the cluster. By studying galaxy collisions, we can gain a better understanding of the nature of dark and light matter and their interactions.

Glossary:
- Dark matter: A form of matter that does not interact with light or other forms of electromagnetic radiation.
- Light matter: Ordinary matter, such as stars, planets, and gas.
- Galaxy cluster: A large group of galaxies that are gravitationally bound together.
- X-rays: High-energy electromagnetic radiation that can penetrate solid materials.

Self-Debate:
- Is there enough evidence to support the existence of dark matter?
- How do galaxy collisions affect the distribution of dark and light matter?
- What is the difference between dark and light matter?

Lesson: Introduction to Corrosion Protection

## Section 1: What is Corrosion Protection?
Corrosion protection refers to the process of preventing or slowing down the degradation of metal surfaces due to chemical reactions with their environment. This can be achieved through various methods such as applying protective coatings, using inhibitors, or controlling the environment.

## Section 2: Types of Corrosion Protection
There are several types of corrosion protection methods, including:

1. Cathodic Protection: This method involves connecting the metal to be protected to a more easily corroded "sacrificial" metal, which corrodes preferentially, thus protecting the primary metal.

2. Coatings: Applying a protective coating, such as paint or a polymer layer, can help prevent corrosion by acting as a barrier between the metal and the environment.

3. Inhibitors: These are chemicals that slow down or prevent corrosion by interfering with the electrochemical reactions that cause it.

4. Environmental Control: Controlling factors such as humidity, temperature, and exposure to corrosive substances can help reduce the rate of corrosion.

## Section 3: Applying Corrosion Protection
To apply corrosion protection, follow these steps:

1. Identify the type of corrosion that is occurring on the metal surface.

2. Choose an appropriate method of corrosion protection based on the type of corrosion and the specific needs of the metal being protected.

3. Apply the chosen method of corrosion protection according to the manufacturer's instructions.

4. Monitor the metal surface regularly to ensure that the corrosion protection is effective and to make any necessary adjustments.

## Glossary:
- Corrosion: The gradual degradation of metal surfaces due to chemical reactions with their environment.
- Inhibitors: Chemicals that slow down or prevent corrosion by interfering with the electrochemical reactions that cause it.
- Cathodic Protection: A method of corrosion protection that involves connecting the metal to be protected to a more easily corroded "sacrificial" metal.
- Coatings: Protective layers applied to metal surfaces to prevent corrosion.
- Environmental Control: Controlling factors such as humidity, temperature, and exposure to corrosive substances to reduce the rate of corrosion.

## Conclusion:
Corrosion protection is an essential process in maintaining the integrity of metal surfaces. By understanding the different types of corrosion protection and how to apply them, we can extend the lifespan of metal objects and prevent costly damage.

8 things my Portuguese mom taught me about home cooking

1. Always be ready to cook for one (or a few) more

I do not remember when it started, but it seemed that our home was always the place where uncles, aunties, and cousins gathered on Sundays — especially on the Sundays when my gradmother decided to go to church. These spontaneous visits were always welcomed by a mother of five wearing a blue apron, greeting her guests and dashing off to the kitchen to add more water and potatoes to her Caldo Verde.

Mum would scan the fridge looking for vegetables she could use to turn the chicken she was about to roast into a chicken stew. If there were not enough potatoes, she would add some good old toasted homemade bread, place it gently on the bottom of a tray, cover it with the stew, stick it in the oven and call it ensopado de frango.

2. Seasoning is like anything else in life, it’s not meant to be measured.

It is meant to be felt. Q.b. — quanto baste — was always the key. The tablespoons were meant to be on the table and not by the pot. Mum used a mix of a punhado of intuition and wooden spoon-tasting techniques to make sure the taste was right. The result of the equation would be confirmed at the end, with a pile of neatly clean plates previously swept with a slice of homemade bread by the sink.

Measures? Keep them for the cakes.

3. A good chef must have many secrets.

Sometimes the hocus-pocus was a little bit of Maizena in the right moment, other times the magical seasoning was caught in the food garden just below the window sill. At times, when the wine packet used to make the meat tastier was empty, mum created some sort of potion with a few drops of vinegar diluted in water, some paprika and some other unforeseen ingredients mixed carefully together in a cup and thrown in the pot when her guests were not looking.

Even today those old secret tips are only revealed to us in a case of true need. Like when one of my brothers tried to surprise his wife in Mexico, or when I tried to prove — in the middle of the Colombian Andes, hundreds of miles away from the sea — that my mum’s Caldeirada de Peixe, which she has been perfecting since she was 9-years-old, is the most delicious thing ever created.

4. A bowl of soup a day is what keeps the doctor away.

An apple may too, but it doesn’t raise you from the dead like my mum’s nutritious soups. Even on pizza nights, soup came first.

5. You’ll never be able to replicate your mother’s food.

The 15-year-old me once sat down watching my mother’s moves like a hawk, taking notes on the amount of onions, garlic, bay leafs, olive oil, potatoes and carrots needed to make a nice creamy soup. I’d make sure to take the bay leaves out before liquefying the ingredients, and to add the watercress, turnip greens, or spinach leaves after and let them boil in the cream for extra flavour.

But by the time I got the cream right, mum had moved on to adding turnips, courgettes and leeks too. To make it really challenging, she even started adding the chayote she used to grow on an apricot tree.

6. Keep the spices to a minimum and the taste to a maximum.

“Curry? I do not like to add those things,” mother would say. Her trick has always been to let tomatoes taste like tomatoes, and potatoes like potatoes. Cook it slow in the beginning and push it to the maximum towards the end when you hear the doorbell ring.

7. You don’t need to eat leftovers as you left them.

Make sure you know how to recycle them properly. If there are boiled potatoes, use them for soup. If there are vegetables and fish, stick them in a frying pan with olive oil, onion and garlic q.b. and call it into roupa velha. Roasted chicken leftovers? Shred them, add some eggs, and turn them into frango à brás. Just like in the old days, when grandma cooked a feijoada à Portuguesa and turned it into cozido à Portuguesa the following day and used the rest of the meat to make sopa de cozido.

8. You can cook from anything, the limit is your imagination

Even if you are in California and your hosts open their massive fridge filled with all sort of sauces and salad dressings and announce there is nothing to eat, you can find something. Onions, a packet of small sausages and garlic sauce, olive oil and rice can be turned into a garlic sausage risotto. There is always something to create.

Lesson: Home Cooking Skills

Introduction:

Home cooking is an essential life skill that can help individuals save money, eat healthily, and bond with family and friends. In this lesson, we will learn eight things that my Portuguese mother taught me about home cooking. These skills will help you become a confident and creative home cook.

Section 1: Always Be Ready to Cook for One (or a Few) More

Topic 1: Welcome Guests with Delicious Food

Question: How can you welcome guests with delicious food?
Answer: By always being ready to cook for one or a few more people, you can welcome guests with delicious food. This means having ingredients on hand and knowing how to quickly prepare a meal for unexpected visitors.

Topic 2: Make Use of What You Have

Question: What does it mean to make use of what you have?
Answer: Making use of what you have means using the ingredients you already have in your fridge and pantry to create a delicious meal. It also means being resourceful and creative with your cooking.

Practical Example: If you have leftover roasted chicken, you can make chicken soup by adding vegetables and water. If you don't have enough potatoes, you can add toasted bread to the soup and call it ensopado de frango.

Section 2: Seasoning Is Like Anything Else in Life, It's Not Meant to Be Measured. It's Meant to Be Felt.

Topic 1: Understanding Quantities

Question: How do you measure seasoning?
Answer: Seasoning is not meant to be measured. Instead, it is meant to be felt. You add seasoning until it tastes good, and you can adjust the quantity based on your taste buds.

Topic 2: Tasting Techniques

Question: How do you ensure that the taste is right?
Answer: To ensure that the taste is right, you need to use a mix of intuition and wooden spoon-tasting techniques. You can taste the food at different stages of cooking to determine if it needs more salt, pepper, or any other seasoning.

Practical Example: If you are making soup, you can taste it to see if it needs more salt or pepper. You can also add more seasoning as you go along until it tastes just right.

Section 3: Conclusion

In conclusion, home cooking is an essential life skill that can help you save money, eat healthily, and bond with family and friends. By following the tips and techniques learned in this lesson, you can become a confident and creative home cook.

Gray – The New Neutral

A color historically represented in business suits and storm clouds, gray has recently surfaced as a fresh and invigorating neutral. Living directly in the middle of white and black, it does a fabulous job of representing an approachable blend of the two. Gray is frequently used in print and other media for its ability to highlight all others colors paired with it.

One surprising feature of this color is its capacity to blend with natural fibers. The woven materials in these rooms bring a warm balance to the cooler grays. Check out these images, they may inspire you to bring a little (anything but dreary) gray into your life.

Levolor® Panel Track Blind: Woven Screen

In addition to being a great solution for covering a sliding glass door, these panel track blinds add an eclectic element to an otherwise traditional room. The gray walls anchor the space while the natural look of the area rug and window treatment add warmth.

A softer feel is using gray as an accent like these cellular shades. The crisp white walls open up the room and by using the top-down/bottom-up feature of these shades, light is still allowed in while maintaining privacy.

A pale, sophisticated gray is used on the walls of this elegant, yet casual dining room. The faux wood blinds are very versatile in their application and best of all, simple to maintain.

Our BG designer, Katie, has been creating bright looks for windows and rooms for over ten years. Katie has great ideas and "picks” for your windows. She will be sharing with you her design choices and seasonal recommendations throughout the year. Katie reminds you that all our BG window blinds, shades and drapes are all custom made for you. Each one is hand crafted to your size, color, fabric and special requests with our added attention to quality and detail. Katie will make sure you love your windows.

grep matches against string tokens, so you have to either:

figure out the right string match for the number range you want (e.g., for 300-400, you might do something like grep -E [34].., with appropriate additional context added to the expression and a number of additional .s equal to your floating-point precision)
convert the number strings to actual numbers in whatever programming language you prefer to use and filter them that way

I'd strongly encourage you to take the second option.

Lesson: How to Filter Floating Point Numbers

Introduction:

In this lesson, we will learn how to filter floating point numbers based on a certain range. We will cover the following topics:

1. Understanding floating point numbers
2. Using regular expressions to filter floating point numbers
3. Converting floating point numbers to integers
4. Filtering integers using logical operators

1. Understanding floating point numbers

Floating point numbers are used to represent real numbers with decimal points. They are composed of an integer part and a fractional part, separated by a decimal point. For example, 3.14 is a floating point number with an integer part of 3 and a fractional part of 0.14.

2. Using regular expressions to filter floating point numbers

Regular expressions are a powerful tool for filtering text based on specific patterns. However, they are not very efficient when it comes to filtering floating point numbers. This is because regular expressions match against strings, not against numerical values. Therefore, we need to convert floating point numbers to strings before applying the regular expression.

For example, if we want to filter all numbers greater than 100, we can use the following regular expression:

grep '[1-9]\d*'

This will match any string that contains at least one digit between 1 and 9, followed by zero or more digits. However, this will also match strings such as "100" and "1000", which are not greater than 100. To fix this, we can add additional constraints to the regular expression, such as:

grep '^[1-9]\d*'

This will match only strings that start with a digit between 1 and 9, followed by zero or more digits.

3. Converting floating point numbers to integers

Another approach to filtering floating point numbers is to convert them to integers and then filter the integers using logical operators. This can be done using the built-in `float()` function in many programming languages.

For example, in Python, we can use the following code to convert a floating point number to an integer:

num = 3.14
integer_num = int(num)

This will give us the integer part of the floating point number, which is 3. We can then use logical operators to filter the integers based on our criteria.

4. Filtering integers using logical operators

Once we have converted the floating point numbers to integers, we can filter them using logical operators such as `>` (greater than), `<` (less than), and `>=` (greater than or equal to).

For example, if we want to filter all numbers greater than or equal to 100, we can use the following code in Python:

nums = [3.14, 150.001, 200.5]
filtered_nums = [num for num in nums if int(num) >= 100]

This will give us the following list of filtered numbers:

[150.001, 200.5]

Conclusion:

In this lesson, we learned how to filter floating point numbers based on a certain range. We covered the basics of floating point numbers and then moved on to using regular expressions and converting floating point numbers to integers to filter them. Finally, we used logical operators to filter the integers based on our criteria.

Glossary:
- Floating point number: A numerical value that contains a decimal point.
- Regular expression: A sequence of characters that define a search pattern.
- Integer: A whole number, without a fractional part.
- Logical operator: An operator that performs a logical operation, such as greater than, less than, or greater than or equal to.

Title: Introduction to Icon Themes and their Design

## Chapter 1: What are Icon Themes and why are they important?

An icon theme is a collection of graphics that represent various actions, objects, or programs on a computer system. These graphics are used in user interfaces to make it easier for users to identify and access different features of their operating system or software applications. Icon themes are important because they help users navigate their computer systems more efficiently and visually appealing. They also provide consistency across different applications and systems, making it easier for users to learn and use new software.

## Chapter 2: Design Elements of Icon Themes

There are several design elements that go into creating an effective icon theme. These include:

1. Color: Colors play an essential role in creating an icon theme that is visually appealing and easily recognizable. Designers must choose colors that complement the overall design of the interface while still being distinct enough to stand out from other elements on the screen.

2. Shape: The shape of an icon should be simple and easy to recognize. Designers often use geometric shapes such as circles, squares, or triangles to create icons that are easily identifiable at different sizes and angles.

3. Style: The style of an icon refers to the way it is drawn or rendered. This can include details such as line thickness, shadowing, or texture. A consistent style across all icons in an icon theme helps create a cohesive look and feel.

4. Size: The size of an icon is crucial because it affects how easily users can recognize and interact with it. Icons should be large enough to be easily tapped or clicked on touch screens but not so large that they overwhelm the interface.

5. Clarity: An effective icon theme should be clear and easy to understand. Designers must ensure that the meaning of each icon is unambiguous and that there are no confusing similarities between different icons.

## Chapter 3: Creating Your Own Icon Theme

Creating your own icon theme can be a fun and rewarding experience. Here are some steps you can follow:

1. Choose a color scheme: Select a color scheme that complements the overall design of your interface. Consider using colors that are consistent with your brand or website's color scheme.

2. Sketch out your ideas: Before you start designing your icons, sketch out your ideas on paper or digitally using a drawing tool. This will help you visualize how your icons will look and ensure that they are visually appealing.

3. Choose your style: Decide on a style for your icons. You can choose between flat, vector, or pixel-based styles. Each style has its advantages and disadvantages, so choose the one that best suits your needs.

4. Create your icons: Use graphic design software to create your icons. Make sure to keep your design elements in mind as you work, such as color, shape, style, and size.

5. Test your icons: Once you have created your icons, test them in different environments to ensure that they look good and function properly. Test them on different devices and operating systems to ensure that they are compatible.

## Chapter 4: Examples of Icon Themes

There are many icon themes available for different operating systems and software applications. Here are a few examples:

1. GNOME: GNOME is a popular desktop environment for Linux-based operating systems. It includes its own icon theme called "Adwaita," which features simple, flat designs in various colors.

2. Windows: Windows uses its own icon theme, which includes both generic icons (such as a folder or a document) and application-specific icons (such as Microsoft Word or Adobe Photoshop).

3. macOS: macOS uses a combination of its own icon theme and third-party icon sets. Apple's design guidelines dictate that all icons must be consistent in style and color.

4. Material Design Icons: Material Design Icons is a popular icon set that follows Google's Material Design guidelines. It features over 3,000 icons in various styles and colors.

## Conclusion

Icon themes are an essential part of any user interface, providing users with a visual way to interact with their computer systems. By understanding the design elements that go into creating an effective icon theme, you can create your own unique and visually appealing icons. There are many icon themes available for different operating systems and software applications, each with its own unique style and color scheme.

text: Well, nuts. Apparently, the camera has picked up an intermittent, and needs some work. I've taken it down temporarily while I work on it, but I'll hopefully it will be a quick fix, and I can have it back up and running shortly.. Actually, I'm kind of surprised that it's done as well as it has for as long as it has. The camera itself was designed as an indoor unit, to sit on top of your desk or monitor. I've had it mounted outdoors and exposed to almost two years' worth of summer heat, winter cold, and dry and wet humidity extremes that it was never designed to handle. It's done pretty well with them so far - at least up until now.. Thanks for your patience.
