text: Eli Reed Blues Trio. In 2004, Eli “Paperboy” Reed stepped in to a basement studio in Boston, Massachussetts with a few friends and and a plan: To record the combination of Downhome Blues, R&B and Soul that they had been experimenting with in rehearsal and at clubs around the city.. Now, 10 years later, things are quite different. Reed has gone on to become a star on the international Soul scene, with three more full-length albums, many singles and hundreds of live shows around the world under his belt. As the 10 year anniversary of “Walkin’ and Talkin” approached, though, Reed began to think more and more about the magic that happened that day in the studio and that it might be time to revisit it.. Now, with Reed, the three of them are reuniting to celebrate the 10 year anniversary of that classic album with a tour and a vinyl-only reissue. This is a once in a lifetime even to see Eli “Paperboy” Reed return to his Raw Blues roots with just his guitar, his voice and his old friends supporting.

Title: Introduction to Chemical Exfoliation

### Section 1: What is Chemical Exfoliation?
Chemical exfoliation is a process that uses chemicals to remove the top layer of dead skin cells, revealing smoother, brighter, and more radiant skin. It is an effective way to improve the appearance of fine lines, wrinkles, and uneven texture.

### Section 2: How does Chemical Exfoliation work?
Chemical exfoliation works by breaking down the bonds between dead skin cells and the skin's surface. This can be achieved through the use of alpha-hydroxy acids (AHAs), beta-hydroxy acids (BHAs), or enzymes such as papain, bromelain, or pepsin. These ingredients help to dissolve the "glue" that holds dead skin cells together, allowing them to be gently sloughed off.

### Section 3: Why is Chemical Exfoliation important?
Chemical exfoliation is important because it helps to remove the outermost layer of dead skin cells, which can build up over time and cause skin to appear dull, dry, and uneven in texture. By removing this layer, the skin appears smoother, brighter, and more radiant. Additionally, chemical exfoliation can help to improve the appearance of fine lines, wrinkles, and other signs of aging.

### Section 4: How often should I use Chemical Exfoliation?
The frequency of chemical exfoliation will depend on your skin type and the specific product you are using. Generally, chemical exfoliation should be used 1-2 times per week. It is essential to follow the instructions on the product label and consult with a dermatologist if you have any concerns about the appropriate frequency for your skin type.

### Section 5: What are the benefits of Chemical Exfoliation?
The benefits of chemical exfoliation include:
- Improved skin texture
- Reduced appearance of fine lines and wrinkles
- Increased skin radiance
- Enhanced skin hydration
- Improved skin cell turnover

### Section 6: Conclusion
Chemical exfoliation is an essential skincare routine for those seeking smoother, brighter, and more radiant skin. By using chemical exfoliants, you can improve the appearance of fine lines, wrinkles, and uneven texture. Remember to consult with a dermatologist before starting any new skincare routine, especially if you have sensitive skin or a history of skin conditions.

The present invention relates to a method of testing controllable switching devices arranged in a full bridge configuration.
If a crane holding a heavy load in a stationary condition is commanded to move, the brake then released and the motor drive engaged, an open or shorted silicon controlled rectifier (SCR) present in a bridge supplying rectified power to the crane motor could then cause insufficient torque to be provided to support the load. To avoid this situation torque proving in cranes is usually accomplished before releasing the brake by commanding a low torque from the drive. The current regulator loop is checked to see if a predetermined level of armature current is developed.
A prior art method of checking an SCR bridge monitored the voltage across each of the cells of the bridge by measuring the three AC input voltages as well as the two DC output rails to check for a collapsing voltage when the cells were fired into the motor filter. This approach requires extra voltage sensors and will not detect an open cell in parallel with a good cell in a dual bridge configuration.
It is an object of the present invention to provide SCR test of SCRs arranged in a full bridge configuration which does not require any additional voltage or current sensors than those required for controlling the drive.
It is a further object of the present invention to provide a drive with improved maintainability capable of identifying open or short circuited SCRs.
It is a still further object of the present invention to provide a method of SCR testing that will detect open or short circuited SCRs in a dual bridge rectifier.

Lesson: Understanding Controllable Switching Devices in a Full Bridge Configuration

**Introduction**
Controllable switching devices are essential components in electrical systems that allow us to control the flow of electricity. In this lesson, we will learn about controllable switching devices arranged in a full bridge configuration and their applications in various industries.

**Core Value**
The core value of this lesson is to understand the importance of controllable switching devices in a full bridge configuration and their applications in various industries.

**Section 1: Theoretical Concepts**
A full bridge configuration is a type of electrical circuit where four controllable switching devices are connected in a way that allows for the direct current (DC) output to be controlled. These devices are typically silicon-controlled rectifiers (SCRs) or thyristors, which are semiconductor devices that can control the flow of electricity.

In a full bridge configuration, each of the four switching devices can be either on or off, allowing for complete control over the DC output. The output voltage is determined by the relationship between the on-state and off-state voltages of the SCRs.

**Section 2: Practical Examples**
One practical application of controllable switching devices in a full bridge configuration is in electric vehicle (EV) chargers. EV chargers use a full bridge configuration to convert alternating current (AC) power from the grid into direct current (DC) power that can be used to charge an electric vehicle's battery.

Another application is in industrial motor drives, where controllable switching devices are used to control the speed and torque of motors. This is particularly important in cranes, where insufficient torque can cause the load to fall. To avoid this situation, torque proving is usually accomplished before releasing the brake by commanding a low torque from the drive.

**Section 3: Self-Debating Discussions**
Why are controllable switching devices important in a full bridge configuration?

Answer: Controllable switching devices are important in a full bridge configuration because they allow for complete control over the DC output voltage. This means that the output voltage can be adjusted to meet the needs of various applications, such as EV chargers and industrial motor drives.

What are some practical applications of controllable switching devices in a full bridge configuration?

Answer: Some practical applications of controllable switching devices in a full bridge configuration include EV chargers and industrial motor drives. In EV chargers, controllable switching devices are used to convert AC power from the grid into DC power that can be used to charge an electric vehicle's battery. In industrial motor drives, controllable switching devices are used to control the speed and torque of motors.

**Glossary**
- Controllable switching device: A device that can control the flow of electricity, typically a silicon-controlled rectifier (SCR) or thyristor.
- Full bridge configuration: A type of electrical circuit where four controllable switching devices are connected in a way that allows for the direct current (DC) output to be controlled.

Whether To Refinance Mortgage Or Pay Down Existing Loan

Q: We want to refinance our home loan. We are at 5.75 percent and might be able to get 4.85 percent on a 30-year fixed-rate mortgage. We will save between $87 to $104 dollars per month and we are thinking about adding extra money each month to pay off the loan faster.

With a 30 year loan, I’d pay twice a month and add extra toward the principal each month, because you never know about this economy. Please give me your opinion.

A: There are four important questions to ask yourself before starting a refinance:

1. Will I lower my interest rate? From your email, it’s clear that you meet this test.
2. Will I lower my monthly payment? You’ll save money each month.
3. Will I shorten my loan term? This is an important question because if you have only 25 years left on your loan and are starting up with another 30-year loan, you’ve essentially lost five years of payments. But if you have 25 years left and can refinance to a 15-year mortgage, you’ll come out ahead.
4. What are the costs to refinance? If a lender will charge you so much that it’ll take years to pay off the costs of the refinance with your monthly savings, it may not be worthwhile to refinance.

Of these four questions, the biggest issue is how much time you have left on your loan. In your case, it sounds as though you have enough room to refinance to a 15-year loan. If your monthly payment is less with a 15-year loan, and you can use that savings to prepay the loan further, then you know you’re making a smart move.

But it isn’t really fair to compare monthly payments when a new loan is going to add years of payments. You must also compare what the costs are to close the loan.

The best way to lower the costs on a refinance is to shop around. Talk to at least four or five different types of lenders: A credit union (if you belong to one or can join one); a big box lender (like Chase, Sun-Trust, Wells Fargo, Citibank, or Bank of America); a local mortgage broker; an Internet lender (like ING Direct) or a mortgage aggregator; and a small, local bank that might keep loans in its own investment portfolio.

Before you call any of the lenders, visit AnnualCreditReport.com and get a free copy of your credit history and pay for a credit score. If your credit score is less than 660 or 680, you may not even qualify for an FHA loan, so your time would be best spent cleaning up your credit.

If your credit score is good, then be sure to share that information with lenders. Tell them, “I know you have to pull your own copy of my credit history and score once I officially apply for the loan. But assume this is current. What kind of interest rate, points, fees, etc. would I qualify for?”

Finally, if you do make extra payments to pay down your loan, don’t forget to indicate on your payment that you made an extra payment to be applied towards the principal on your loan. If you have an escrow account for the payment of real estate taxes or insurance, and you don’t specifically say that the extra is to be used to pay down the loan balance, you might be surprised to find out that your extra payments went into the escrow account and not to pay down your debt.

Lesson: How to Make Financial Decisions

Introduction:
Making financial decisions is an important part of life. Whether it's deciding whether to refinance a mortgage or pay down an existing loan, understanding the ins and outs of personal finance can help you make informed choices. In this lesson, we'll explore the key factors to consider when making financial decisions, including interest rates, monthly payments, and loan terms.

Section 1: Understanding Personal Finance

Topic 1: Interest Rates
Interest rates are one of the most important factors to consider when making financial decisions. They determine how much you'll pay in interest over the life of your loan. The higher the interest rate, the more you'll pay in interest over time.

Topic 2: Monthly Payments
Monthly payments are another important factor to consider when making financial decisions. A lower monthly payment means you'll pay less each month, but you may end up paying more in interest over the life of your loan. On the other hand, a higher monthly payment means you'll pay more each month, but you may end up paying less in interest over time.

Topic 3: Loan Terms
Loan terms are also an important factor to consider when making financial decisions. A longer loan term means you'll pay off your loan over a longer period of time, which can result in higher interest payments. A shorter loan term means you'll pay off your loan more quickly, which can result in lower interest payments.

Section 2: Analyzing Your Financial Situation

Topic 1: Determining Your Budget
Before making any financial decision, it's important to determine your budget. This means calculating how much money you have coming in each month and how much you have going out. Once you know your budget, you can determine how much you can afford to spend on a new loan.

Topic 2: Assessing Your Current Debt
Another important factor to consider when making financial decisions is your current debt. If you have a lot of high-interest debt, it may be wise to focus on paying that off before taking out a new loan.

Topic 3: Evaluating Your Credit Score
Your credit score is another important factor to consider when making financial decisions. A higher credit score can help you qualify for lower interest rates, while a lower credit score may result in higher interest rates.

Section 3: Making Informed Decisions

Topic 1: Comparing Loan Options

He is survived by his wife, Nancy, and their two children.1 Regan was formerly served as Professor Emeritus Professor of Philosophy at North Carolina State University. [2] His work focused on the idea that animals possess moral rights similar to those endowed upon humans. He argues for this connection based on the notion that what gives human morality is not rationality, “but the fact that each of us has a life that matters to us.” [1].

Lesson: Animal Rights
Introduction:
Animals have been a part of human society for centuries, but it wasn't until recently that people started questioning their rights. In this lesson, we will explore the concept of animal rights and how it has evolved over time. We will also learn about the key figures in the movement, such as Tom Regan, who played a significant role in shaping our understanding of animal rights.
What are Animal Rights?
Animal rights refer to the belief that animals deserve legal protection and consideration, just like humans. This concept is based on the idea that animals have the ability to feel pain, fear, and joy, and that they should be treated with respect and compassion.
The History of Animal Rights
The concept of animal rights has a long history, dating back to ancient Greece when philosophers such as Aristotle and Pythagoras argued for the moral status of animals. However, it wasn't until the 19th century that the animal rights movement began to gain momentum. In 1824, the British veterinarian Henry Blackwell wrote a book called "The Rights of an Animal," which argued that animals should be treated humanely.
In the 20th century, the animal rights movement grew significantly, thanks to the work of activists such as Peter Singer and Tom Regan. Singer's book "Animal Liberation" (1975) is considered a seminal work in the field, while Regan's "The Case for Animal Rights" (1983) provided a philosophical framework for the movement.
Key Figures in the Animal Rights Movement
Tom Regan was a prominent figure in the animal rights movement. He was a professor of philosophy at North Carolina State University and wrote several books on the subject, including "The Case for Animal Rights." Regan believed that animals had moral rights and that humans had a responsibility to protect them.
Peter Singer is another influential figure in the animal rights movement. He is a professor of bioethics at Princeton University and has written numerous books on the subject, including "Animal Liberation." Singer believes that animals should be treated with respect and compassion, and that their use in research and food production is unjustifiable.
Practical Examples
One practical example of animal rights in action is the use of veganism. Vegans avoid all animal products, including meat, dairy, eggs, and honey. They do so because they believe that animals have the right to live free from harm and that consuming animal products contributes to the suffering of animals.
Another practical example is the use of animal-free products in industries such as cosmetics and clothing. Many companies now offer vegan-friendly products that do not involve the use of animals.
Conclusion
In conclusion, the concept of animal rights has evolved significantly over time, thanks to the work of key figures such as Tom Regan and Peter Singer. By treating animals with respect and compassion, we can create a more humane world for both humans and animals alike.

Lesson: Introduction to Chemical Reactions

## Section 1: Theoretical Concepts
In this lesson, we will learn about chemical reactions and how they can be used to create new compounds. A chemical reaction is a process in which two or more substances come together to form a new substance with different properties. This can happen when two substances combine, when one substance changes into another, or when a substance breaks down into smaller parts.

Chemical reactions follow certain rules, called the laws of chemistry. These laws state that:

1. Matter can neither be created nor destroyed in a chemical reaction.
2. The total mass of the reactants must equal the total mass of the products.
3. The properties of the products depend on the properties of the reactants.

## Section 2: Practical Examples
Let's look at an example of a chemical reaction. Imagine you have a mixture of iron filings and sand. If you heat the mixture, the iron filings will rust, while the sand remains unchanged. This is because the iron reacts with oxygen in the air to form rust, while the sand does not interact with any other substances.

Another example is the reaction between baking soda and vinegar. When you mix these two substances, they produce carbon dioxide gas, water, and a salt. This is a chemical reaction because the properties of the products are different from the properties of the reactants.

## Section 3: Self-Debating Discussion
Now let's think critically about chemical reactions. Why do some reactions produce different products than others? What factors influence the outcome of a chemical reaction? How can we control the conditions of a reaction to get the desired result?

## Glossary:
- Chemical reaction: A process in which two or more substances come together to form a new substance with different properties.
- Laws of chemistry: Rules that govern the behavior of matter during chemical reactions.
- Reactants: Substances that come together to form a new substance.
- Products: The new substance formed by a chemical reaction.
- Iron filings: A substance that can rust when exposed to oxygen.
- Sand: A substance that does not interact with other substances.
- Baking soda: A substance that reacts with vinegar to produce carbon dioxide gas, water, and a salt.
- Vinegar: A substance that reacts with baking soda to produce carbon dioxide gas, water, and a salt.

## Conclusion:
In this lesson, we learned about chemical reactions and how they can be used to create new compounds. We also looked at practical examples and engaged in self-debating discussion to deepen our understanding. By applying the skills gained from this topic, we can solve problems related to chemical reactions in various fields.

Lesson Title: Understanding Limits in Mathematics

Introduction:
In mathematics, limits are essential concepts used to describe the behavior of functions as the input approaches a particular value. In this lesson, we will explore the concept of limits, their applications, and how to evaluate them.

Section 1: Theoretical Concepts

1.1 What is a limit?
A limit is a value that a function approaches as the input approaches a particular value. It is denoted as lim(x->a) f(x) = L, meaning that as x approaches 'a', f(x) gets arbitrarily close to 'L'.

1.2 Types of limits
There are different types of limits, including one-sided limits, infinite limits, and limits at infinity. We will focus on one-sided and infinite limits in this lesson.

1.3 One-sided limits
A one-sided limit is when we consider the behavior of a function as the input approaches from the left or right side. It is denoted as lim(x->a-) f(x) = L or lim(x->a+) f(x) = L, depending on the direction.

1.4 Infinite limits
An infinite limit is when the input approaches a particular value without bound. It is denoted as lim(x->∞) f(x) = L or lim(x->-∞) f(x) = L.

1.5 Continuity and limits
A function is continuous at a point if the limit exists and is equal to the function's value at that point. If the limit does not exist or is different from the function's value, the function is discontinuous at that point.

Section 2: Applications

2.1 Rate of change
Limits can be used to find the instantaneous rate of change of a function. This is useful in understanding how a function's behavior changes as the input changes.

2.2 Derivatives
Limits are used to define derivatives, which represent the instantaneous rate of change of a function with respect to its input. Derivatives are essential in calculus for finding maxima, minima, and other properties of functions.

2.3 Infinite series
Limits are used to determine the convergence of infinite series. A series converges if the limit of the partial sums approaches a finite value as the number of terms increases.

Section 3: Evaluating Limits

3.1 Direct substitution
One method to evaluate limits is by direct substitution, where we plug in the input value approaching the point of interest into the function.

3.2 L'Hôpital's rule
When the limit involves an indeterminate form (e.g., 0/0), we can use L'Hôpital's rule to differentiate the numerator and denominator and find the limit.

3.3 Squeeze theorem
The squeeze theorem states that if a function is sandwiched between two other functions, and the limit of the outer functions exists, then the limit of the middle function exists and is equal to the limit of the outer functions.

Conclusion:
Understanding limits is crucial in mathematics, as they help us understand the behavior of functions as inputs change. Limits have numerous applications, including finding instantaneous rates of change, defining derivatives, and determining the convergence of infinite series. By evaluating limits using various methods such as direct substitution, L'Hôpital's rule, and the squeeze theorem, we can gain deeper insights into the properties of functions.

Lesson: Introduction to Cryptography

## Section 1: Theoretical Concepts
Cryptography is the practice of securing information by encoding it in a way that makes it unreadable to anyone except those who possess the necessary tools or keys to decode it. This is done to protect sensitive information from unauthorized access, tampering, or theft.

## Section 2: Practical Examples
One of the most common examples of cryptography is the use of passwords to secure online accounts. When you create a password, you are essentially encoding your personal information in a way that only you know how to decode it. If someone were to try and guess your password, they would not be able to access your account without the proper key or authorization.

Another example of cryptography is the use of encryption to secure financial transactions over the internet. When you use your credit card to make an online purchase, the information you enter is encrypted before it is transmitted over the internet. This means that even if someone were to intercept the information, they would not be able to read it without the proper decoding tool.

## Section 3: Real-World Scenarios
Cryptography is used in many different industries to protect sensitive information. For example, military communications may use complex encryption techniques to keep their messages secure from enemies. Banks also use cryptography to protect customer information and prevent fraud.

## Glossary
- Encryption: The process of converting plain text into cipher text using an algorithm and a key.
- Decryption: The process of converting cipher text back into plain text using the same algorithm and key.
- Key: A secret piece of information that is used to encode and decode messages.

## Conclusion
Cryptography is an essential tool for protecting sensitive information in today's digital world. By understanding the theoretical concepts and practical applications of cryptography, we can better protect ourselves and our data from unauthorized access or theft.

## Lesson: Establishing Trust in Relationships
### Section 1: Introduction
Establishing trust is an essential part of building relationships. Whether it's personal or professional, trust is the foundation of any successful relationship. In this lesson, we will learn about how consistency and reliability can help establish trust and commitment. We will also explore the importance of giving away ideas for free and when to ask to get paid for your work.
### Section 2: The Importance of Consistency and Reliability
Consistency and reliability are two of the most important factors in establishing trust. When people know what to expect from you, they are more likely to trust you. This means that you need to be consistent in your behavior and actions. You also need to be reliable, which means that you follow through on your promises and deliver on your commitments.
### Section 3: Giving Away Ideas for Free
Giving away ideas for free is an effective way to establish trust. When you give away ideas for free, you show that you are committed to helping others succeed. This can help establish trust and commitment in your relationship. However, you also need to know when to ask for payment. If you are working with clients on a retainer consulting basis, it's important to establish clear boundaries about what services are included in the retainer fee and which require additional compensation.
### Section 4: Practical Examples
Let's consider a real-world scenario where giving away ideas for free could establish trust. Suppose you are a marketing agency that specializes in social media management. You could offer to manage the social media accounts of a potential client for free for a month. This would demonstrate your commitment to helping them succeed and establish trust in your relationship. However, if the client wants to continue working with you beyond the initial month, you would need to establish clear boundaries about what services are included in the retainer fee and which require additional compensation.
### Section 5: Self-Debating Discussions
One way to teach critical thinking is through self-debating discussions. For example, you could ask students to debate whether giving away ideas for free is always the best strategy for establishing trust. Some students may argue that it's always better to charge for your services, while others may argue that giving away ideas for free can establish trust and commitment in certain situations. Encourage students to support their arguments with evidence and examples.
### Section 6: Glossary
- Retainer consulting: A type of consulting arrangement where clients pay a fixed fee for ongoing services over a period of time.
- Ideation: The process of generating new ideas or solutions.
- Brainstorming: A group problem-solving technique that encourages creativity and innovation.
### Conclusion
Establishing trust is essential for building successful relationships. Consistency and reliability are important factors in establishing trust and commitment. Giving away ideas for free can also help establish trust, but it's important to know when to ask for payment. By following the strategies outlined in this lesson, you can establish trust and commitment in your relationships.

Lesson: How to Build a Frontier Fort

## Introduction

In this lesson, we will learn about how to build a frontier fort. We will cover the materials used, the construction process, and the purpose of the fort. By the end of this lesson, you will be able to understand the importance of frontier forts and how they protected early settlers.

## Materials Used

The main materials used to build a frontier fort were huge logs and stone. The logs were typically set horizontally and stacked on top of each other to form a strong structure. The stone was used to create a foundation and reinforce the walls.

## Construction Process

1. Choose a location that is easy to defend and has a good view of the surrounding area.
2. Clear the land and prepare the site for construction.
3. Cut down trees and transport them to the building site.
4. Stack the logs horizontally to form the walls of the fort.
5. Use stone to reinforce the walls and create a foundation.
6. Construct a gate that can be locked to protect the fort from enemies.
7. Build additional structures such as barracks, storage rooms, and a command center within the fort.

## Purpose of the Fort

The purpose of a frontier fort was to protect early settlers from attacks by Native Americans or other enemies. These forts were typically located in remote areas where there were few other settlements. They provided a safe place for people to live and store supplies. The walls of the fort were designed to withstand attacks from cannons, and the gates could be locked to prevent entry by enemies.

## Practical Examples

1. Imagine you are a settler living in the American West during the 1800s. Your town has decided to build a frontier fort to protect against attacks from Native Americans. You are responsible for helping to construct the fort. Describe your process and the challenges you face.

2. Once the fort is completed, you and your fellow settlers move in. Describe a typical day inside the fort, including what activities you engage in and how you interact with others.

## Glossary

**Frontier Fort:** A fort built in a remote area to protect early settlers from attacks by Native Americans or other enemies.

**Log:** A wooden beam used in construction.

**Stone:** A hard, solid material used to create a foundation and reinforce walls.

**Cannon:** A large gun used for attacking forts and other structures.

**Gate:** A door that can be locked to prevent entry by enemies.

**Settler:** A person who moves to a new area to live and establish a community.

## Conclusion

In this lesson, we learned about the materials used to build a frontier fort, the construction process, and the purpose of the fort. We also explored practical examples of what life might have been like inside the fort. By understanding the importance of frontier forts, we can appreciate the sacrifices and challenges faced by early settlers in the American West.

Lesson: Understanding and Working with Holograms

Introduction:
Holograms are 3D images created by interference of light waves. They can be used to store, transmit, and display information. In this lesson, we will explore what holograms are, how they work, and how they can be used to improve our lives.

Section 1: What are Holograms?
A hologram is a 3D image that appears to float in space. It is created by interference of light waves, which means that it can be seen from different angles and perspectives. Holograms can be made of anything, including people, animals, objects, or even scenes from nature.

Section 2: How do Holograms Work?
Holograms work by using lasers to create interference patterns on a photosensitive material. This material is then developed into a holographic plate, which can be used to create a 3D image. The image can be viewed by shining a laser beam onto the plate and observing the resulting interference pattern.

Section 3: Applications of Holograms
Holograms have many practical applications, including:
- Data storage: Holograms can be used to store large amounts of data in a small space. This is because the data is stored in the form of interference patterns, which take up less space than traditional data storage methods.
- Telecommunications: Holograms can be used to transmit information over long distances without the need for physical transmission lines. This is because the information is encoded in the interference patterns, which can be transmitted wirelessly.
- Security: Holograms can be used to prevent counterfeiting and piracy. By embedding a hologram on a product, it becomes difficult for someone to duplicate it without being detected.

Section 4: Benefits of Working with Holograms
Working with holograms can provide many benefits, including:
- Enhancing creativity: Holograms can help us to visualize ideas and concepts in a more tangible way, which can stimulate our creativity and imagination.
- Improving communication: Holograms can help us to communicate complex ideas and concepts more effectively by providing a visual representation that can be easily understood by others.
- Boosting problem-solving skills: Holograms can help us to see problems from different perspectives, which can help us to develop more effective solutions.

Section 5: Conclusion

Q:

Find the third rational point on the curve: $y^2 = x^3 + 8$

I am trying to find a third rational point on the curve $y^2 = x^3 + 8$
According to the my professor's solution, the idea is to find two rational points then solve for the third point.
These are the first two points:
$$(x,y) = (1, 3)~~~\text{and}~~~(x,y)=\left(-\frac{7}{4}, \frac{13}{8}\right)$$
The point $(1,3)$ is fairly straight forward and we can find it by trial and error, but we are also supposed to find the second point by trial and error. Is there a systematic way to go about this without having to try so many numbers?

A:

Consider the elliptic curve $y^2 = x^3 + A$ for any $A\in\mathbb{Q}$. Given a rational point $(x_*,y_*)$, we can then find another rational point $(x,y)$ by considering the intersection of the tangent line through that point, see figure below (which is a slight modification of one found in Silverman's book mentioned below).
$~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~$
The slope of the curve at the point $(x_*,y_*)$ is $\frac{dy}{dx} =\frac{3x_*^2}{2y_*}$ so the tangent line is given by
$$y = y_* + \frac{3x_*^2}{2y_*}(x-x_*)$$
This line intersects the curve at the point $(x,y)$ determined by the qubic equation
$$\left(y_* + \frac{3x_*^2}{2y_*}(x-x_*)\right)^3 = x^2 + A$$
Expanding the brackets above we see that $x_*$ is a double root and the sum of the roots is $\frac{9x_*^4}{4y_*^2}$. This gives us that the third root is
$$x = \frac{x_*^4-8Ax_*}{4y_*^2} \implies y = \frac{8A^2 -20Ax_*^3 - x_*^6}{8y_*^3}$$
This shows that if $(x_*,y_*)$ is any rational point on the curve the so is $(x,y)$ given by the formula above. As a small historical note I might add that this result was first derived by Claude Bachet already in 1621, see e.g. Rational points on elliptic curves by Joseph H. Silverman.
Applying this procedure with $A=8$ to the known rational points $(x_*,y_*) = (2,4)$ and $(x_*,y_*) = (1,3)$ gives us the points $\left(-\frac{7}{4},\pm\frac{13}{8}\right)$ and by continuing to apply the formula we can construct even more rational points:
$$\left(\frac{31073}{2704}, \pm\frac{5491823}{140608}\right)$$
$$\left(\frac{(892933489418780033}{326211856441766464}, \pm\frac{994822284545339876177687617}{186315768712277487672882688}\right)$$
$$\ldots$$
The numbers gets quite big after a few itterations.

A:

Hint : $y^2 = (x+2)(x^2-2x+4)$ - What can you say about rational points now?

A:

There is a systematic way. Draw a picture of $y^2 = x^3 + 8$ on graph paper.
http://www.printablepaper.net/category/graph
Per request: I am very, very old. When learning to draw graphs, I used a special kind of treeware called "PAPER," of a special type with little squares already printed on it. This special kind is called Graph Paper. If a printer is available, one may download a free pdf of graph paper, and print out a copy whenever one needs to draw a graph.
I made one. I bought a programmable calculator in 1983. I put in $\sqrt{x^3 + 8}$ and drew the following:

Note that I bought an inexpensive flatbed scanner for my home computer, maybe about 2012, which is how you get to see the picture.

Lesson: Finding Rational Points on an Elliptic Curve

### Introduction

An elliptic curve is a smooth projective curve of genus 1 with a specified base point, O. It is defined by an equation of the form y^2 = x^3 + Ax + B, where A and B are constants. The goal of this lesson is to teach you how to find rational points on an elliptic curve.

### Section 1: What is an Elliptic Curve?

An elliptic curve is a mathematical concept that represents a smooth projective curve of genus 1. It is defined by an equation of the form y^2 = x^3 + Ax + B, where A and B are constants. The curve has a group structure, which means that it can be added and subtracted like regular numbers.

### Section 2: Finding Rational Points on an Elliptic Curve

To find rational points on an elliptic curve, we need to consider the intersection of the tangent line through a given point with the curve. This process is called "silverman's algorithm" and is described in detail in his book "Elliac Curves: Theory of Elasticity."

First, we start by choosing a random point P on the curve. Then, we draw a line through P that is tangent to the curve at that point. We call the point Q where the line intersects the curve. Next, we reflect Q across the x-axis to get R. Finally, we reflect R across the y-axis to get S.

If S is the point at infinity, then P, Q, and R are inverses of each other, meaning that P + Q = R and P - Q = R. If S is not the point at infinity, then we repeat the process with R as our new point P.

We continue this process until we reach a point that is the point at infinity or until we have gone around the curve three times. At this point, we have found a rational point on the curve.

### Section 3: Examples

Let's consider the elliptic curve y^2 = x^3 + 2. We want to find a rational point on this curve.

We choose a random point P = (1, 2). Then, we draw a line through P that is tangent to the curve at that point. We call the point Q where the line intersects the curve. Next, we reflect Q across the x-axis to get R. Finally, we reflect R across the y-axis to get S.

After performing these steps, we find that Q = (-1, -2), R = (0, 0), and S = (0, 0). Since S is the point at infinity, we have found a rational point on the curve: (0, 0).

### Conclusion

In this lesson, we learned about elliptic curves and how to find rational points on them. We saw that by considering the intersection of the tangent line through a given point with the curve, we can find additional rational points. We also worked through an example to demonstrate the process.


text: A Holocaust survivor tells his compelling family story of escape and survival in China and Australia during WW2. Living in Berlin in 1939, three-year-old Peter Nachemstein and his parents were forced to escape Nazi Germany by fleeing to Shanghai – one of the only havens left for them and 18,000 other European Jews. Although safe, they became displaced and isolated from the rest of their family, who were scattered across Europe. In Escape from Berlin, Peter Nash retraces what became of his family members following the devastating impact of WW2. Using remarkable photographs and documents to bring their captivating stories to life, Peter recounts his own experiences of dislocation as a young boy in alien Shanghai, and then later as a teenager and adult in Australia. Meticulously researched and impeccably detailed, Escape from Berlin brings light to a fascinating but not widely known chapter of Holocaust history in a family story that reflects the experiences of many in the Jew.

Particle velocity probe

A particle velocity probe is a probe capable of measuring the acoustic particle velocity.

The only particle velocity probe to date has been produced by Microflown Technologies and is called the Microflown.

The Microflown sensor is a MEMS based transducer able to directly measure acoustic particle velocity. Very small sized elements are created on silicon wafers under a clean room technology. The sensing element consists of two ultra-thin wires (thinner than a strand of human hair). These wires are platinum resistors that act as temperature sensors. They are powered by an electrical current which causes them to heat up. Local temperature variations cause changes in the wires resistance. When the acoustic particle velocity (sound) propagates across the wires, it asymmetrically alters the temperature distribution around the resistors (wires). The resulting resistance difference provides a broad band (20 Hz up to at least 10 kHz) linear signal with a figure-of-eight directivity that is proportional to the acoustic particle velocity.
