Lesson: Introduction to Photography

## Section 1: What is Photography?
Photography is the art of capturing light and turning it into an image. It is a way of recording moments and memories that can be shared with others. Photography can be done with a camera, which captures the light and turns it into an image on film or digital media.

## Section 2: Understanding Exposure
Exposure is one of the most important concepts in photography. It refers to the amount of light that enters the camera and hits the sensor or film. The three elements that control exposure are shutter speed, aperture, and ISO. Shutter speed is the length of time that the camera's shutter is open, allowing light to enter. Aperture is the size of the opening in the lens that allows light to enter. ISO is the sensitivity of the camera's sensor or film to light.

## Section 3: Composition Techniques
Composition is the arrangement of elements in a photograph to create a visually pleasing image. There are several composition techniques that photographers use to create interesting images. These include the rule of thirds, leading lines, symmetry, and patterns.

## Section 4: Lighting Techniques
Lighting is an important part of photography. Good lighting can make an image look better, while poor lighting can ruin an image. There are several lighting techniques that photographers use to create interesting images. These include natural light, artificial light, and reflectors.

## Section 5: Editing Techniques
Editing is the process of adjusting an image after it has been taken. There are several editing techniques that photographers use to improve their images. These include cropping, adjusting color and contrast, and adding filters.

## Conclusion
Photography is a fun and creative hobby that can be enjoyed by people of all ages. By understanding the basics of exposure, composition, and lighting, and using editing techniques, anyone can take great photos. With practice and patience, anyone can become a skilled photographer.

MIT can detect alien weather, including clouds laced with liquid rock

For a long time, simply proving the existence of exoplanets was a big deal. We had over a hundred years of fiction and even non-fiction based on the assumption that our universe is absolutely packed with alien planets — but we simply couldn’t prove that they existed. Now, with the list of planets outside our solar system ballooning by dozens or more at a time, the stakes are quite a bit higher. Simply finding and identifying exoplanets is no longer enough to impress, and now you have to actually learn something about them. That’s been the goal of a team from MIT, which this week publishes a piece detailing their pioneering new method for looking at alien weather.

That’s much easier said than done, however, for many of the same reasons that it took so long to confirm the existence of exoplanets in the first place: they are very small and very dark. Most exoplanets have been confirmed thanks to so-called “transit” in front of their parent star, producing a blown-own planetary silhouette. Astronomers have worked to pull much more useful data from these transits than simple size and speed, and this MIT paper represents a major step toward that goal. By looking at the fluctuations in any light spilling around the edges of an alien world, these researchers can gain some insight into its atmosphere. Particularly, the team can derive some real information about the clouds that sit on top of this atmosphere.

The technique starts with a climate model that uses predicted pressure values to predict how different substances will behave on the surface of a given planet. This gives the team a mixture of gaseous products to model, and the software then looks at how these gasses might interact on the surface of an alien world with particular properties. The software spits out a prediction for the spectrographic readings we’d expect to be associated with each of these possible cloud formations. After that, all they need to do is compare their actual readings to the list of predictions — if any of the values fits observation too well to be coincidence, that’s probably our culprit.

The team used Kepler 7b as a test bed for its technique, and their readings suggest that the planet has clouds made of vaporized rock. On Earth these substances would be solid, or at most liquid near the planet’s interior. However Kepler 7b is absolutely gargantuan (one reason it was one of the first five confirmed exoplanets) and orbits less than a twentieth of as far from its star as the Earth does from Sol; sometimes referred to as a “hot Jupiter,” Kepler is a nightmarish furnace to make Venus look hospitable.

NASA’s TESS mission could make even these findings look tame.

These incredible rock-clouds are just another bullet point on the list of reasons exoplanetologists have the coolest scientific conferences. Their results often read like the ramblings of a science fiction author, narrating a magellan-like voyage through a universe far too surreal to ever actually exist. Worlds have been shown to rain diamond, or simply to be composed almost entirely of it. Others have multiple sunsets or abnormally long or short years. Astronomers have found planets that are several times older than our Sun, and others that are younger than our upright ancestors. The search for alien planets is the search for the edges of what’s possible, and techniques like this one are proving that we are very far from finding them.

While Kepler was mankind’s first tailored planet hunter, NASA is already well underway on its successor: the Transiting Exoplanet Survey Satellite, or TESS. TESS should take our understanding of exoplanets to a new level, and unlike many areas of astronomy, in this case the tinier the detail of the observation the more relatable it is to the average person. It’s hard to imagine a super-Jupiter, but easier to imagine clouds. Exoplanetology will almost certainly be one of the most publicly lauded areas of astronomy in years to come.

Lesson: Detecting Alien Weather

Introduction:

Alien weather refers to the atmospheric conditions and weather patterns found on planets outside our solar system, also known as exoplanets. Studying alien weather can provide valuable insights into the composition, temperature, and climate of these distant worlds. In this lesson, we will explore the methods used by scientists to detect alien weather and analyze its characteristics.

Section 1: Understanding Exoplanets

Before we dive into detecting alien weather, let's first understand what exoplanets are. An exoplanet is a planet that orbits a star outside our solar system. These planets are extremely difficult to detect because they are very small and very far away from us. However, scientists have developed several methods to find and study exoplanets, including the transit method and the radial velocity method.

Section 2: Detecting Alien Weather

Once an exoplanet has been detected, scientists can begin studying its weather patterns. One way to do this is by observing the light that passes through the planet's atmosphere. When light passes through a gas, it can scatter in different directions. By analyzing the scattered light, scientists can determine the composition of the gas in the atmosphere. This method is called transmission spectroscopy.

Another way to study alien weather is by observing the heat emitted by the planet. As the planet orbits its star, it can cause changes in the star's temperature. By measuring these changes, scientists can learn about the planet's temperature and its weather patterns. This method is called the secondary eclipse method.

Section 3: Analyzing Alien Weather Data

After collecting data on alien weather, scientists can use this information to learn about the planet's atmosphere, temperature, and climate. For example, if a planet has a thick atmosphere, it may be able to support life. If the planet has a temperature similar to Earth's, it may be habitable.

Conclusion:

Detecting and studying alien weather is a fascinating area of research that can provide valuable insights into the properties of exoplanets. By understanding the atmospheric conditions and weather patterns of these distant worlds, we can gain a better understanding of the potential for life beyond our solar system.

Lesson: Introduction to Carbon Markets
## I. Overview of Carbon Markets
Carbon markets are financial instruments that allow countries and organizations to trade carbon emissions. They were created as part of the Kyoto Protocol, an international agreement aimed at reducing greenhouse gas emissions. Carbon markets allow countries and organizations to meet their emission reduction targets by purchasing credits from other entities that have already reduced their emissions.
## II. How Carbon Markets Work
Carbon markets operate through a system of allowances or credits. Each allowance represents a ton of carbon dioxide that can be emitted. Organizations that exceed their emissions limits must purchase allowances from other entities that have not used up their allotment. This creates a market where allowances can be bought and sold.
## III. Types of Carbon Markets
There are two main types of carbon markets: compliance markets and voluntary markets. Compliance markets are regulated by governments and require organizations to purchase allowances to meet their emission reduction targets. Voluntary markets are created by private companies and allow organizations to purchase offsets to meet their own emission reduction goals.
## IV. Benefits of Carbon Markets
Carbon markets provide several benefits. First, they provide a financial incentive for organizations to reduce their emissions. Second, they create a market for emission reductions, which can help drive innovation and technological advancements. Finally, they provide a way for countries to work together to reduce global emissions.
## V. Challenges of Carbon Markets
One of the biggest challenges of carbon markets is ensuring that they are effective in reducing emissions. This requires careful monitoring and verification of emissions reductions, as well as strong enforcement mechanisms to prevent fraud and abuse. Additionally, there are concerns about the cost of compliance and the potential for negative impacts on developing countries.
## VI. Conclusion
Carbon markets are complex financial instruments that play an important role in global efforts to reduce emissions. By understanding how they work and the benefits and challenges they present, we can make informed decisions about their use and effectiveness.

text: On May 25th, 2013 my boyfriend of a little over two years, Kevin, asked me to marry him! As promised, here’s our proposal story :D. Back in the day (when I was much more lithe) I did a little bit of modeling on the side. It’s been years since I’ve consistently gone on jobs but I still receive requests from photographers once in a while so when I received a request to work with J. Davis Photography, it wasn’t too out of the ordinary. I am taking an international trip here in a few days so the idea of making a little bit of money from a photo shoot sounded good and Kevin encouraged me to take the gig. I thought, “why not?” and accepted the offer. After a few weeks of grooming and (trying) to get back into shape, the day of the shoot arrived and I was pumped!

Sen. Bernie Sanders will call for a federal ban on building for-profit charter schools in a major education policy address to be delivered Saturday in South Carolina, a senior campaign official for the 2020 presidential contender tells USA TODAY.

Additionally, Sanders will pledge to impose a moratorium on using taxpayer funds on charter school expansion in communities if he’s elected president, a position that the NAACP has been advocating.

The speech by Sanders comes one day after the 65th anniversary of the landmark Brown v. Board of Education ruling handed down by the Supreme Court, which ruled segregation in public schools to be illegal.

“Our school system can no longer put up fences for black and brown children,” Sanders said in an op-ed in the Asheville Citizen-Times, part of the USA TODAY Network, published Friday. “On this 65th anniversary of the Brown vs Board of Education decision, we are going to tear down those barriers and create an education system that works for all people, not just the wealthy and powerful.”

Charters are publicly funded but privately run, and have grown in popularity around the country since their inception more than 25 years ago. Advocates say their relative independence – they face fewer instructional and bureaucratic regulations, and are largely free from collective bargaining – allow educators to innovate.

Charters can be run by for-profit or non-profit companies; the vast majority are run by nonprofits.

Response from charter school advocates

Advocates for charter schools blasted the Sanders’ proposal.

“Sanders’ call is out of touch – as usual – with what African Americans want,” said Amy Wilkins, the senior vice president of advocacy for the National Alliance of Public Charter Schools. “More disturbing, the senator – for personal political gain – would literally lock African American students into schools that have failed them for generations.”

Charter reckoning:Betsy DeVos calls for more charter schools even as they spark investigations across the country

DeVos:Warren vows to pick a former public school teacher to serve as education secretary

Charter strike:Nation's first charter school strike ends, but could portend more battles on choice

Teachers unions around the U.S. have been pressing for local and federal lawmakers to stem the proliferation of charters, which they say are siphoning funding away from traditional public schools.

The NAACP, National Education Association and the American Federation of Teachers have also taken aim at charters for intensifying racial segregation in schools, as nearly 1 out of 5 charter schools have a 99% percent minority student body.

President Trump’s education secretary, Betsy DeVos, has been a longtime supporter of charter schools. DeVos, and her husband, Dick, the heir to the Amway fortune, have spent millions of dollars on behalf of the charter school movement in their home state of Michigan.

The speech by Sanders to address the role of charters comes as he tries to win over African American voters in the early-voting state of South Carolina.

Where the rest of the field stands

The move to target charters by Sanders also offers an opportunity for the senator to set himself apart from former Vice President Joe Biden, the Democratic presidential frontrunner, with a message that will likely resonate with teachers union members.

During his time in the White House, President Obama was supportive of merit pay and charter schools, both issues generally opposed by teachers unions. The Obama administration’s education reform effort, dubbed “Race to the Top”, gave states a chance to compete for federal grant money if they adopted a series of reforms, including link student performance to teacher evaluations. Biden’s brother, Frank Biden, is also a former executive in a company that developed charter schools.

Other Democratic contenders also have backed school choice in the past.

Before winning a U.S. senate seat, Cory Booker was a fierce advocate of charters during his time as mayor in Newark. A third of Newark’s students now attend charter schools. The New Jersey city’s charters are among the highest-performing the in the country, according to Stanford University’s Center for Research on Education Outcomes.

Sanders is also expected to call for mandating that charter schools comply with the same oversight requirements as public schools, establishing rules that require at least half of all charter school boards are teachers and parents, and codifying that charters disclose student attrition rates, non-public funding sources, and financial interests of the charter network.

The Vermont senator is the first major 2020 Democratic candidate to call for a ban on for-profit charters or a moratorium on funding the expansion of charters.

Nearly 3.2 million students, roughly 6% of all public school students, attended nearly 7,000 charter schools nationwide last school year. Enrollment was up 5 percent from the previous year, according to the National Alliance for Public Charter Schools

Lesson: The Importance of Public Education

Introduction:
Public education is a fundamental right for every child in the United States. It is the responsibility of the government to ensure that every child has access to quality education, regardless of their background or socioeconomic status. In this lesson, we will explore the importance of public education and why it is essential to fight for equal access to education for all children.

Section 1: The History of Public Education in the United States
Public education in the United States has a long and complicated history. Before the Civil War, education was primarily the responsibility of families and religious institutions. However, after the war, the government began to take a more active role in providing education to all children. The Brown v. Board of Education case in 1954 marked a significant milestone in the fight for equal access to education for all children, regardless of their race.

Section 2: The Importance of Public Education
Public education is essential for several reasons. Firstly, it provides children with the opportunity to acquire knowledge and skills that will help them succeed in life. Secondly, it helps to promote social mobility and reduce income inequality. Finally, it plays a crucial role in maintaining a democratic society by ensuring that citizens are educated and informed about current events.

Section 3: The Threat of Charter Schools to Public Education
While charter schools were initially intended to provide an alternative to traditional public schools, they have become a threat to public education. They siphon off resources and funding from traditional public schools, leading to inequalities in education. Additionally, they do not have the same accountability measures as traditional public schools, leading to a lack of transparency and oversight.

Section 4: The Need for Action
It is essential to fight for equal access to education for all children. This means opposing the expansion of charter schools and advocating for increased funding for traditional public schools. Additionally, we must work to ensure that teachers are adequately compensated and supported in their efforts to educate our children.

Conclusion:
In conclusion, public education is essential to the success and well-being of our society. We must work to ensure that all children have access to quality education, regardless of their background or socioeconomic status. By doing so, we can create a more equitable and just society for all.

Glossary:
- Public education: Education provided by the government and funded by taxpayers
- Charter schools: Publicly funded schools that are run by private organizations
- Brown v. Board of Education: A landmark Supreme Court case that declared segregation in public schools to be unconstitutional
- Social mobility: The ability to move up in society based on personal effort and talent
- Income inequality: The unequal distribution of income among individuals in a society

Self-Debating Discussion:
Why is it essential to fight for equal access to education for all children? What are some potential consequences of not providing equal access to education? How can we ensure that teachers are adequately compensated and supported in their efforts to educate our children?

Lesson Title: Carbon Capture and Sequestration

Introduction:
Carbon capture and sequestration (CCS) is a process that captures carbon dioxide emissions from power plants and industrial processes before they enter the atmosphere. This process involves capturing carbon dioxide, transporting it to a storage site, and storing it safely and securely. In this lesson, we will learn about the importance of CCS, how it works, and its potential benefits.

Section 1: Importance of CCS

Topic 1: Why is CCS important?
- CCS is an important technology that helps reduce greenhouse gas emissions and mitigate climate change.
- It allows us to continue using fossil fuels while reducing their environmental impact.
- CCS can also help us transition to cleaner energy sources by providing a bridge between traditional energy sources and renewable energy sources.

Topic 2: What are the benefits of CCS?
- CCS reduces greenhouse gas emissions and helps slow down climate change.
- It allows us to continue using fossil fuels while reducing their environmental impact.
- CCS can help create jobs and stimulate economic growth in the energy sector.
- It can also help improve air quality and public health by reducing emissions from power plants and industrial processes.

Section 2: How does CCS work?

Topic 1: How is carbon dioxide captured?
- Carbon dioxide is captured using specialized equipment called carbon capture systems.
- These systems are designed to capture carbon dioxide emissions from power plants and industrial processes before they enter the atmosphere.
- The captured carbon dioxide is then compressed and transported to a storage site.

Topic 2: How is carbon dioxide stored?
- Once carbon dioxide is captured, it needs to be stored safely and securely to prevent it from entering the atmosphere.
- There are several ways to store carbon dioxide, including underground storage in depleted oil and gas reservoirs, deep saline aquifers, and coal seams.
- Storing carbon dioxide underground is safe and effective, as long as it is done correctly.

Section 3: Potential benefits of CCS

Topic 1: What are the potential benefits of CCS?
- CCS has the potential to significantly reduce greenhouse gas emissions and mitigate climate change.
- It can help us transition to cleaner energy sources by providing a bridge between traditional energy sources and renewable energy sources.
- CCS can also help create jobs and stimulate economic growth in the energy sector.
- Additionally, it can help improve air quality and public health by reducing emissions from power plants and industrial processes.

Topic 2: How can CCS be implemented successfully?
- To implement CCS successfully, we need to invest in research and development to improve the technology and make it more cost-effective.
- We also need to develop and implement policies and incentives that encourage the use of CCS.
- Finally, we need to work with industry partners to develop and deploy CCS technologies at scale.

Conclusion:
Carbon capture and sequestration is an important technology that can help us reduce greenhouse gas emissions and mitigate climate change. By capturing and storing carbon dioxide safely and securely, we can continue to use fossil fuels while reducing their environmental impact. As we transition to cleaner energy sources, CCS can provide a bridge between traditional energy sources and renewable energy sources. By implementing CCS successfully, we can create jobs, stimulate economic growth, and improve air quality and public health.

Lesson: How to Analyze Visual Art

## Introduction
In this lesson, we will learn how to analyze visual art. We will start by understanding the different elements of art, such as line, shape, color, and texture. Then, we will learn how to interpret the meaning behind the artwork by analyzing the subject matter, composition, and style. Finally, we will apply these techniques to analyze a piece of art called "Paris Syndrome" by an unknown artist.

## Section 1: Elements of Art
The first step in analyzing visual art is understanding the basic elements of art. These elements are line, shape, color, and texture.

**Line** - A line is a mark made on a surface, and it can be straight, curved, thick, or thin. Lines can convey movement, direction, and mood.

**Shape** - A shape is a closed area defined by lines or curves. It can be geometric (square, circle, triangle) or organic (freeform, irregular).

**Color** - Color refers to the hue, saturation, and value of a pigment or light. Colors can evoke emotions, create contrast, and attract attention.

**Texture** - Texture refers to the way a surface feels to the touch. It can be smooth, rough, bumpy, or any other tactile quality.

## Section 2: Interpreting the Meaning
Now that we understand the basic elements of art, let's move on to interpreting the meaning behind the artwork. There are several aspects to consider when analyzing a piece of art: subject matter, composition, and style.

**Subject Matter** - This refers to the objects or ideas depicted in the artwork. The subject matter can tell us about the artist's interests, values, and experiences.

**Composition** - This refers to the arrangement of elements within the artwork, such as the placement of lines, shapes, and colors. A well-composed artwork can create balance, rhythm, and harmony.

**Style** - This refers to the artist's unique approach to creating art, which can be influenced by their culture, background, and personal preferences. An artist's style can reveal their unique perspective and vision.

## Section 3: Analyzing "Paris Syndrome"
Now that we understand the elements of art and how to interpret the meaning behind an artwork, let's apply these techniques to analyze "Paris Syndrome."

**Line** - In this artwork, we can see that the lines are mostly straight and vertical, conveying a sense of stability and structure. However, there are also some curved lines, which add a sense of fluidity and movement.

**Shape** - The shapes in this artwork are mostly geometric, with squares and triangles being the most prominent. These shapes create a sense of order and balance.

**Color** - The colors used in this artwork are muted and subdued, evoking a sense of melancholy and sadness. The colors are also mostly cool, such as blues and grays, which can create a calming effect.

**Texture** - The texture in this artwork is smooth, which creates a sense of polish and sophistication.

**Subject Matter** - The subject matter of this artwork seems to be about the disillusionment that some tourists experience when they visit Paris. The title, "Paris Syndrome," suggests that the artwork is commenting on the unrealistic expectations that people may have when they travel.

**Composition** - The composition of this artwork is well-balanced, with the geometric shapes arranged in a way that creates a sense of harmony and stability.

**Style** - The style of this artwork is minimalist, with a focus on simplicity and clarity. The use of muted colors and simple shapes creates a sense of elegance and refinement.

Conclusion
In this lesson, we learned how to analyze visual art by examining the elements of art, interpreting the meaning behind the artwork, and applying these techniques to analyze a piece of art called "Paris Syndrome." By understanding the basic elements of art and how to interpret the meaning behind an artwork, we can gain a deeper appreciation for the artistic process and the messages that artists convey through their work.

Main stream of magnetic heads mounted on a hard disc drive of a computer are thin film magnetic heads such as composite MR-inductive type heads in which inductive elements are used to write records and MR (magnetoresistive) elements or GMR (giant MR) elements are used to read records.
As shown in JP 2001-20044A, these thin film type magnetic heads are composed of a composite material comprised of a plurality of materials which have different hardness, for example, a substrate such as ALTIC (Al2O3—TiO2), a ceramic protective and/or insulation film such as alumina (Al2O3), and a metallic film which is a magnetic material such as permalloy (Fe—Ni) and Sendust (Fe—Al—Si) and the like.
In the process of producing thin film magnetic heads, a bar having a row of sliders is cut out from a wafer in which a number of electromagnetic transducing elements are arranged in the form of a matrix and an area of the surface of the bar that becomes ABS (air bearing surface) is lapped to obtain a flat surface.
The conventional grinding process of ABS of a slider is conducted while controlling the throat height (TH) and MR height.
The TH is one of the factors which affect recording performance of the thin film magnetic head and is a distance at a magnetic pole portion between the ABS and the terminus of the insulator which electrically isolates a thin film coil (TH shown in FIG. 3)
The MR height (MR-h) is one of the factors which affect reading performance of the thin film magnetic head and is a length of the MR element measured from the ABS (indicated as MR-h in FIG. 3). The details are described in JP2001-200244 A. In FIG. 3, the respective parts are as follows. 1: an ALTIC substrate, 2: an alumina insulation film, 3: a bottom shield film (Sendust, permalloy or the like), 4: an alumina film, 5: an MR element, 6: an alumina film, 7: a head shield film (permalloy or the like), 8: an alumina film, 9: write pole tip (permalloy or the like), 10: an alumina protective film, and 11: a coil conductor.
Conventionally, the lapping treatment of the surface which would become the ABS was performed by dripping a free abrasive slurry composition using diamond abrasive particles onto a face plate formed from a soft metal such as tin, and reciprocating a workpiece (which may be cut into a bar if necessary) to be polished on the face plate.
For examples, patent documents 1 and 2 disclose free abrasive slurry compositions suitable to form a flat surface which is to be used as ABS of thin film magnetic heads.
However, during the grinding operation using such free abrasive slurry composition, it was necessary to continue supplying the slurry composition without cessation and thus the consumption of the slurry composition was enormous, the cost was high and a particle problem that the abrasive particles pierce the surface to be polished occurred.
On the other hand, during the finish grinding operation of surfaces or end faces of precision parts, it is possible to use a grinding or polishing sheet which is composed of an abrasive layer formed on a substrate sheet. Since the grinding sheet retains fixed abrasive particles and accordingly any expensive free slurry composition is not necessary, one sheet may be used repeatedly. Therefore, the production cost can be reduced. For example, patent document 3 discloses a grinding sheet adapted to be used to finish surfaces or end faces of precision parts.

Lesson: How to Read and Understand Real Estate Listings
Introduction:
Real estate listings are a common way to find information about homes for sale or rent. However, they can be confusing to read and understand. In this lesson, we will learn how to read and interpret real estate listings by analyzing the different components of a typical listing.
Section 1: Understanding the Basics
- Location: The location of a property is usually listed first in a real estate listing. It includes the address, neighborhood, city, state, and zip code. This information is important because it helps potential buyers or renters determine the distance from their workplace, schools, and other important locations.
- Price: The price of the property is also listed in the listing. It is usually the first thing that potential buyers or renters look at. The price can be listed as a range or a specific amount.
- Square Footage: Square footage refers to the size of the property. It is usually measured in square feet and is an important factor to consider when looking for a home.
- Bedrooms and Bathrooms: The number of bedrooms and bathrooms in a property is also listed in the listing. These are important factors to consider when looking for a home, especially if you have a large family or require multiple bathrooms.
Section 2: Reading Between the Lines
- Amenities: Amenities refer to the features and services provided by the property or the neighborhood. These can include a swimming pool, gym, clubhouse, or parking. Amenities can be a deciding factor when choosing a home.
- Upgrades: Upgrades refer to any improvements made to the property. These can include new appliances, flooring, or a remodeled kitchen. Upgrades can increase the value of a property and are important to consider when looking for a home.
- Views: Views refer to the scenery visible from the property. This can include mountains, ocean, or city views. Views can be a valuable asset and can increase the value of a property.
Section 3: Practical Examples
- Let's say we are looking for a 3-bedroom house in Los Angeles, California, within a budget of $500,000. We can use the following search criteria:
    - Location: Los Angeles, California
    - Price: $500,000
    - Bedrooms: 3
    - Bathrooms: Any
    - Square Footage: Any
- After running our search, we get a list of properties that match our criteria. We can then analyze each property based on the information provided in the listing, such as the location, price, square footage, bedrooms, and bathrooms.
Conclusion:
In this lesson, we learned how to read and interpret real estate listings by analyzing the different components of a typical listing. We covered the basics, such as location, price, and square footage, and went deeper into amenities, upgrades, and views. By applying these concepts to a practical example, we can make informed decisions when looking for a home.

Salt tolerance in Lycopersicon species. III. Detection of quantitative trait loci by means of molecular markers.
A segregating population derived from a cross between L. esculentum cv Madrigal and a line of L. pimpinellifolium was used to identify genetic markers linked to QTLs involved in salinity tolerance in terms of yield, under a conductivity of 15 dS/m (171.1 mM NaCl). Six markers resulted, associated with QTLs affecting average fruit weight, fruit number and total weight under salinity. One of them, Aco-1, behaves reversely to the expectation from parental means; this and other features make it a promising target to obtain salt-tolerant tomatoes. Epistatic interactions were also found, thus affecting the criteria for marker-assisted selection. Although only 41% of the loci assayed were polymorphic, a high efficiency in identifying QTLs was achieved, since 43% of the marker loci are linked to QTLs for the trait under study.

Lesson: Introduction to Quantitative Trait Loci (QTL) Mapping in Plant Breeding

**Overview:** In this lesson, we will learn about Quantitative Trait Loci (QTL) mapping, a technique used in plant breeding to identify genes responsible for specific traits. We will focus on a study conducted on tomato plants to identify QTLs associated with salt tolerance.

**Objectives:**

1. Understand the concept of QTL mapping and its importance in plant breeding.
2. Identify the steps involved in QTL mapping.
3. Learn about the role of molecular markers in QTL mapping.
4. Understand the significance of epistasis and its impact on QTL mapping.
5. Apply the knowledge gained to solve real-world problems related to plant breeding and agriculture.

**Section 1: Introduction to QTL Mapping**

Quantitative Trait Loci (QTL) mapping is a technique used in plant breeding to identify the genes responsible for specific traits. This information can be used to develop new plant varieties with desirable characteristics, such as resistance to diseases or tolerance to environmental stresses.

**Section 2: Steps Involved in QTL Mapping**

1. Population creation: A population of plants is created by crossing two parent plants with desired traits.
2. Phenotyping: The offspring plants are grown under controlled conditions to measure their phenotype (observable characteristics).
3. Genotyping: DNA samples are collected from each plant to determine their genetic makeup.
4. Data analysis: Statistical methods are applied to identify the chromosomal regions associated with the trait of interest.
5. Validation: The results are validated using independent populations or other experimental designs.

**Section 3: Role of Molecular Markers in QTL Mapping**

Molecular markers are DNA sequences that can be used to track the presence of specific genes or genomic regions. These markers are used to create a genetic map of the plant's chromosomes, which helps in identifying the location of QTLs associated with the trait of interest.

**Section 4: Epistasis and its Impact on QTL Mapping**

Epistasis refers to the interaction between different genes that can affect the expression of a particular trait. This interaction can influence the accuracy of QTL mapping, as it may cause the effects of one gene to mask or enhance the effects of another gene.

**Section 5: Applications of QTL Mapping**

QTL mapping has several applications in plant breeding and agriculture, including:

1. Development of new plant varieties with improved traits, such as drought tolerance or pest resistance.
2. Identification of genes responsible for specific traits, which can be used for gene editing or genetic engineering.
3. Predicting the performance of new plant varieties based on their genetic makeup.

**Glossary:**

- QTL: Quantitative Trait Loci
- Phenotype: Observable characteristics of an organism
- Genotype: Genetic makeup of an organism
- Epistasis: Interaction between different genes that can affect the expression of a particular trait

**Conclusion:**

In conclusion, QTL mapping is a powerful tool in plant breeding that allows scientists to identify the genes responsible for specific traits. By understanding the genetic basis of these traits, breeders can develop new plant varieties with improved characteristics, such as salt tolerance in tomato plants. This knowledge can be applied to address various challenges in agriculture, such as developing crops that can thrive in saline soils or resist pests and diseases.

An overview of information goods pricingby Wei-Lun Chang, Soe-Tsyr YuanInternational Journal of Electronic Business (IJEB), Vol. 5, No. 3, 2007Abstract: Although information economy has been the focus of considerable research, no unified and exhaustive classification model for current pricing methods exists. This work presents a novel unifying pricing framework. Each category in the framework is defined by the structural elements that accounts for its behaviour and particular aims. This work also identifies the implicit joints among categories as the basis for optimising prices (only in terms of different perspectives). The benefits of the unifying framework are that it provides a conceptual abstract model that differentiates between different pricing methods, and positions the future effectual pricing

Lesson Title: Introduction to Information Goods Pricing

Introduction:
Information goods are intangible products that are produced and distributed digitally. Examples of information goods include music, movies, e-books, software, and online subscriptions. Pricing information goods can be challenging because they do not have the same physical characteristics as tangible goods. In this lesson, we will learn about different pricing methods for information goods and how they can be used to maximize profits.

Section 1: Pricing Methods for Information Goods

1.1. Price Skimming

Price skimming is a pricing strategy where a company sets a high price for a new product or service to capture early adopters. As the product becomes more popular, the price is lowered to attract a larger customer base. This method is commonly used in the technology industry when introducing new gadgets or software.

1.2. Penetration Pricing

Penetration pricing is a pricing strategy where a company sets a low price for a new product or service to attract a large number of customers quickly. The idea is to gain market share and establish a customer base, which can then be monetized through other means such as add-on services or upgrades.

1.3. Geographical Pricing

Geographical pricing is a pricing strategy where a company charges different prices for the same product or service based on the location of the customer. This method takes into account factors such as shipping costs, taxes, and local competition.

1.4. Dynamic Pricing

Dynamic pricing is a pricing strategy where a company changes the price of a product or service based on demand. This method uses algorithms to adjust prices in real-time based on factors such as time of day, customer behavior, and inventory levels.

Section 2: Advantages and Disadvantages of Pricing Methods

2.1. Price Skimming

Advantage: High initial revenue
Disadvantage: Limited customer base

2.2. Penetration Pricing

Advantage: Large customer base
Disadvantage: Lower profit margins

2.3. Geographical Pricing

Advantage: Customization to local markets
Disadvantage: Complexity in managing multiple prices

2.4. Dynamic Pricing

Advantage: Flexibility in adjusting prices
Disadvantage: Difficulty in maintaining consistency

Section 3: Applying Pricing Strategies to Real-World Scenarios

3.1. Apple iPhones

Apple uses a combination of price skimming and penetration pricing for its iPhone products. When the iPhone was first introduced, it was priced at a premium to attract early adopters. As the product became more popular, Apple lowered the price to attract a wider customer base.

3.2. Netflix

Netflix uses dynamic pricing to adjust its subscription fees based on the region. In some countries, Netflix offers a lower-priced basic plan with advertising, while in others, the basic plan is ad-free. This pricing strategy allows Netflix to tailor its offering to local markets and adapt to changing customer preferences.

Conclusion:
In this lesson, we learned about different pricing methods for information goods and their advantages and disadvantages. We also applied these strategies to real-world scenarios to see how they are used in practice. By understanding these pricing methods, businesses can make informed decisions about how to price their products and services to maximize profits and attract customers.

Glossary:
- Information goods: Intangible products that are produced and distributed digitally.
- Pricing strategy: A plan for setting prices on a product or service.
- Penetration pricing: A pricing strategy where a company sets a low price to attract a large number of customers quickly.
- Geographical pricing: A pricing strategy where a company charges different prices based on the location of the customer.
- Dynamic pricing: A pricing strategy where a company changes the price of a product or service based on demand.

Planting Instructions

Pumpkin Planting info:

Plant your pumpkin seeds outside after all chance of frost has passed and the soil temperature is 65 F. Even though pumpkins need a lot of room to grow, we always plant more pumpkin seeds than we think we may need to increase the chance of each vine setting fruit. Plan on needing a minimum of 20 square feet for each plant – this can be found on the edge of the garden where the vines can trail down, or in an unconventional spot in your yard that has ample space.

The warmer the soil, the faster the seeds will germinate, so mound the soil to help the sun heat it faster. Plant 3-5 pumpkin seeds about 1 inch deep in each mound. Once they germinate, thin to 2 of the healthiest sprouts.

Pumpkins are 80-90% water, so they need a lot of it to grow. The secret is to only water pumpkins when they need it. If the plant looks healthy, there is no need to water daily. When the soil is dry and the plant looks limp, give it a long deep drink. Deep but infrequent watering results in a healthier plant.

Most pumpkin varieties take between 85-125 days to mature. If you would like to have pumpkins on October 1st, count backwards to decide when to plant.

Lesson: Understanding Taxation

**Introduction**

Taxation is a topic that many people find confusing and frustrating. However, understanding taxation is essential for everyone, as it affects our daily lives. In this lesson, we will explore the basics of taxation, including what it is, how it works, and why it matters.

**Section 1: What is Taxation?**

Taxation is the process by which governments raise revenue to fund public services and programs. It is a compulsory payment that individuals and businesses must make to the government, usually based on their income or consumption.

**Section 2: How does Taxation Work?**

There are several types of taxes, including income tax, sales tax, property tax, and corporate tax. Each type of tax is calculated differently, but they all serve the same purpose - to generate revenue for the government.

Income tax is a tax levied on individuals or businesses based on their income. The amount of tax owed depends on the individual's or business's tax bracket, which is determined by their income level.

Sales tax is a tax imposed on the purchase of goods and services. The amount of tax owed is typically a percentage of the purchase price.

Quasi physisorptive two dimensional tungsten oxide nanosheets with extraordinary sensitivity and selectivity to NO2.
Attributing to their distinct thickness and surface dependent physicochemical properties, two dimensional (2D) nanostructures have become an area of increasing interest for interfacial interactions. Effectively, properties such as high surface-to-volume ratio, modulated surface activities and increased control of oxygen vacancies make these types of materials particularly suitable for gas-sensing applications. This work reports a facile wet-chemical synthesis of 2D tungsten oxide nanosheets by sonication of tungsten particles in an acidic environment and thermal annealing thereafter. The resultant product of large nanosheets with intrinsic substoichiometric properties is shown to be highly sensitive and selective to nitrogen dioxide (NO2) gas, which is a major pollutant. The strong synergy between polar NO2 molecules and tungsten oxide surface and also abundance of active surface sites on the nanosheets for molecule interactions contribute to the exceptionally sensitive and selective response. An extraordinary response factor of ∼30 is demonstrated to ultralow 40 parts per billion (ppb) NO2 at a relatively low operating temperature of 150 °C, within the physisorption temperature band for tungsten oxide. Selectivity to NO2 is demonstrated and the theory behind it is discussed. The structural, morphological and compositional characteristics of the synthesised and annealed materials are extensively characterised and electronic band structures are proposed. The demonstrated 2D tungsten oxide based sensing device holds the greatest promise for producing future commercial low-cost, sensitive and selective NO2 gas sensors.

4. Analyze the results of experiments conducted using 2D tungsten oxide nanosheets for NO2 gas sensing.

**Section 1: Introduction to Gas Sensing with Two-Dimensional Materials**

Two-dimensional (2D) materials are a class of materials that have unique properties due to their thin, planar structure. These materials have attracted significant attention in recent years due to their potential applications in various fields, including electronics, energy storage, and sensing. One of the most promising applications of 2D materials is in gas sensing.

**Section 2: Synthesis of 2D Tungsten Oxide Nanosheets**

The synthesis of 2D tungsten oxide nanosheets involves the following steps:

1. Sonication of tungsten particles in an acidic environment: This step involves mixing tungsten particles with a strong acid to create a slurry. The acid dissolves the tungsten particles, leaving behind a solution containing tungsten ions.

2. Thermal annealing: After the sonication step, the tungsten ions are heated to a high temperature in an oxygen-rich environment. This step causes the tungsten ions to oxidize and form 2D nanosheets.

3. Purification: The final step involves washing the 2D nanosheets to remove any impurities and then drying them.

**Section 3: Properties of 2D Tungsten Oxide Nanosheets for NO2 Gas Sensing**

There are several properties of 2D tungsten oxide nanosheets that make them effective for detecting NO2 gas:

1. High surface-to-volume ratio: 2D materials have a large surface area, which allows them to interact with a large number of gas molecules. This increases their sensitivity to gas changes.

2. Modulated surface activities: The surface properties of 2D materials can be easily modified by changing their thickness or composition. This allows for the tuning of their sensitivity to specific gases.

3. Increased control of oxygen vacancies: The presence of oxygen vacancies on the surface of 2D materials can enhance their interaction with NO2 gas molecules.

**Section 4: Experimental Results**

Experiments have shown that 2D tungsten oxide nanosheets are highly sensitive and selective to NO2 gas. The nanosheets exhibit a strong response to even low concentrations of NO2, making them suitable for use in air quality monitoring systems.

**Glossary:**

- Two-dimensional (2D) materials: Materials with a thickness of only a few atoms or molecules.
