Q:

Do the eigenvalues of a matrix need to be in the same field as the elements of the matrix?

Do the eigenvalues of a matrix need to be in the same field as the elements of the matrix? I believe they do not since, for instance, I was taught that the trace is the sum of the eigenvalues and this would mean that this is not always the case. What puzzles me is that I have seen people claiming that some real matrix has no eigenvalues simply because the eigenvalues were all complex numbers. Were they right?

A:

That depends upon the context. If, say, you have a $n\times n$ real matrix and and someone asks you what are its eigenvalues, then it is implicit that you should provide the real eigenvalues. And perhaps that there is none. On the other hand, it may be implicit that, in fact, you are after the complex eigenvalues.
On the other hand, if the matrix is real, then the trace is real, but it may well have non-real eigenvalues. For instance, $\left[\begin{smallmatrix}0&-1\\1&0\end{smallmatrix}\right]$ has null trace, but its eigenvalues are $\pm i$.

Lesson: Real Matrix Eigenvalues

Introduction:

In this lesson, we will learn about the eigenvalues of a real matrix. We will explore whether the eigenvalues of a matrix need to be in the same field as the elements of the matrix and discuss the concept of trace.

Core Value:

The eigenvalues of a real matrix need not be in the same field as the elements of the matrix. However, the trace of a real matrix is the sum of its eigenvalues, and this sum must be real.

Section 1: Eigenvalues of a Real Matrix

Topic 1: Definition

An eigenvalue of a matrix is a scalar value that, when multiplied by the matrix, results in a new matrix with the same eigenvector.

Topic 2: Properties

1. If a matrix has an eigenvalue, then it also has an eigenvector associated with that eigenvalue.
2. The set of all eigenvectors of a matrix forms an orthogonal basis for the vector space of the matrix's columns.
3. The eigenvalues of a matrix are real if and only if the matrix is real and symmetric.

Section 2: Trace of a Real Matrix

Topic 1: Definition

The trace of a real matrix is the sum of its eigenvalues.

Topic 2: Properties

1. The trace of a matrix is always real.
2. If a matrix has an eigenvalue, then its trace is non-zero.
3. If a matrix has distinct eigenvalues, then its trace is equal to the sum of the products of the eigenvalues and their multiplicities.

Section 3: Complex Matrices

Topic 1: Definition

A complex matrix is a matrix whose entries are complex numbers.

Topic 2: Properties

1. The eigenvalues of a complex matrix can be real or complex.
2. The trace of a complex matrix is the sum of its real parts.
3. The eigenvalues of a complex matrix are related to its singular values.

Conclusion:

In this lesson, we have learned that the eigenvalues of a real matrix need not be in the same field as the elements of the matrix. However, the trace of a real matrix is the sum of its eigenvalues, and this sum must be real. We also explored the properties of eigenvalues and trace for real matrices and complex matrices.

Rituximab (anti-CD20) therapy of B-cell lymphomas: direct complement killing is superior to cellular effector mechanisms.
Rituximab (IDEC-C2B8, Mabthera(R)) is a chimeric (human-mouse) monoclonal antibody (MoAb) against the B-cell specific CD20-antigen. It has been used for the clinical treatment of non-Hodgkin's lymphomas, but variable clinical results suggest that some lymphoma cells remain resistant. In the present study we have evaluated the relative efficiencies of humoral and cell-mediated effector mechanisms complement-dependent cytotoxicity (CDC), antibody-(ADCC), complement-(CDCC) dependent cellular cytotoxicity and apoptosis on lymphoma cell killing by rituximab. Rituximab activated the cytolytic complement (C) cascade and induced a strong CDC, but the rituximab-triggered ADCC and CDCC were relatively ineffective. The CDC was strongly enhanced by antibodies against the C inhibitor CD59 (protectin). Neutralization of CD55 (DAF) and CD46 (MCP) had a similar but weaker effect. Rituximab also induced apoptosis but in a cell line-dependent fashion. The results strongly emphasize the role of direct CDC as the major, fast and efficient effector mechanism of rituximab. In the immunotherapeutic treatment of B-cell lymphomas, it is important to consider the role of C-regulatory proteins as an escape mechanism of the malignant cells. Our results suggest that the effect of rituximab therapy could be enhanced by combining it with neutralization of CD59.

Lesson: Introduction to Immunology - Complement System

### Section 1: Theoretical Concepts
The complement system is an essential part of the immune system that helps to protect the body from infections and diseases. It consists of a series of proteins that circulate in the blood and tissues, which work together to eliminate pathogens and damaged cells. The complement system can be activated by antibodies, cytokines, or through the classical pathway.

The classical pathway is initiated by the binding of the complement protein C1q to antibodies (IgG) that are bound to the surface of a pathogen or damaged cell. This binding activates the C1r and C1s proteins, which cleave C4 and C2 to form the C3 convertase. The C3 convertase cleaves C3 into C3a and C3b, which then bind to the surface of the pathogen or damaged cell.

The alternative pathway is initiated by the spontaneous hydrolysis of C3, which allows it to bind to the surface of the pathogen or damaged cell. The binding of C3 activates the C3 convertase, which cleaves C3 into C3a and C3b. The cleaved C3b then binds to the surface of the pathogen or damaged cell.

The lectin pathway is initiated by the binding of mannose-binding lectin (MBL) or ficolins to specific carbohydrate patterns on the surface of the pathogen or damaged cell. This binding activates the MBL-associated serine proteases (MASPs), which cleave C4 and C2 to form the C3 convertase.

Once the C3 convertase is formed, it cleaves C3 into C3a and C3b, which then bind to the surface of the pathogen or damaged cell. The binding of C3b activates the C3 convertase, which cleaves C3 into C3a and C3b. The cleaved C3b then binds to the surface of the pathogen or damaged cell, forming the C5 convertase.

The C5 convertase cleaves C5 into C5a and C5b, which then bind to the surface of the pathogen or damaged cell. C5b then associates with C6 and C7 to form the membrane attack complex (MAC), which creates pores in the pathogen's or damaged cell's membrane, leading to cell lysis.

### Section 2: Questions and Answers
1. What is the complement system?
Answer: The complement system is an essential part of the immune system that helps to protect the body from infections and diseases. It consists of a series of proteins that circulate in the blood and tissues, which work together to eliminate pathogens and damaged cells.

2. How does the classical pathway of the complement system work?
Answer: The classical pathway is initiated by the binding of the complement protein C1q to antibodies (IgG) that are bound to the surface of a pathogen or damaged cell. This binding activates the C1r and C1s proteins, which cleave C4 and C2 to form the C3 convertase. The C3 convertase cleaves C3 into C3a and C3b, which then bind to the surface of the pathogen or damaged cell.

3. What is the alternative pathway of the complement system?
Answer: The alternative pathway is initiated by the spontaneous hydrolysis of C3, which allows it to bind to the surface of the pathogen or damaged cell. The binding of C3 activates the C3 convertase, which cleaves C3 into C3a and C3b. The cleaved C3b then binds to the surface of the pathogen or damaged cell.

4. What is the lectin pathway of the complement system?
Answer: The lectin pathway is initiated by the binding of mannose-binding lectin (MBL) or ficolins to specific carbohydrate patterns on the surface of the pathogen or damaged cell. This binding activates the MBL-associated serine proteases (MASPs), which cleave C4 and C2 to form the C3 convertase.

5. What is the C3 convertase?
Answer: The C3 convertase is an enzyme that cleaves C3 into C3a and C3b. The cleaved C3b then binds to the surface of the pathogen or damaged cell, forming the C5 convertase.

6. What is the C5 convertase?
Answer: The C5 convertase is an enzyme that cleaves C5 into C5a and C5b. The cleaved C5b then associates with C6 and C7 to form the membrane attack complex (MAC), which creates pores in the pathogen's or damaged cell's membrane, leading to cell lysis.

7. What is the membrane attack complex (MAC)?
Answer: The membrane attack complex (MAC) is a pore-forming complex that is formed when C5b binds to C6 and C7. The MAC creates pores in the pathogen's or damaged cell's membrane, leading to cell lysis.

### Section 3: Practical Examples and Real-World Scenarios
A common example of the complement system in action is during an infection. When a pathogen enters the body, the immune system recognizes it as foreign and activates the complement system. The complement system helps to eliminate the pathogen by forming the membrane attack complex (MAC), which creates pores in the pathogen's membrane, leading to cell lysis. Additionally, the complement system also helps to recruit other immune cells to the site of infection and enhances phagocytosis, further aiding in the elimination of the pathogen.

Another example of the complement system in action is during an autoimmune disease. In some cases, the immune system mistakenly attacks the body's own tissues. The complement system can be activated in this situation, leading to tissue damage and inflammation. By understanding the complement system and its role in autoimmune diseases, researchers can develop treatments that target the complement system to reduce tissue damage and inflammation.

Lesson: The American Justice System - An Introduction

## Section 1: Introduction to the American Justice System

The American justice system is a complex network of laws, institutions, and procedures that work together to maintain order and ensure fairness in society. In this lesson, we will explore the basics of the American justice system, including its history, structure, and key players.

### Questions and Answers

**Question:** What is the American justice system?

**Answer:** The American justice system is a set of laws, institutions, and procedures that are designed to maintain order and ensure fairness in society. It includes the courts, the police, and other government agencies that are responsible for enforcing the law and protecting individual rights.

**Question:** How did the American justice system evolve?

**Answer:** The American justice system has its roots in English common law, which was brought to the colonies by early settlers. Over time, the system has evolved to reflect the unique needs and values of American society. Today, the American justice system is based on a combination of constitutional law, statutory law, and judicial precedent.

**Question:** Who are the key players in the American justice system?

**Answer:** The key players in the American justice system include judges, prosecutors, defense attorneys, and jurors. Judges are responsible for presiding over trials and making decisions based on the law and the evidence presented. Prosecutors represent the government in criminal cases and are responsible for presenting evidence and arguing for convictions. Defense attorneys represent individuals accused of crimes and work to prove their innocence or reduce their punishment. Jurors are members of the community who are selected to hear evidence and make decisions in criminal and civil trials.

## Section 2: The Structure of the American Justice System

The American justice system is divided into two main branches: the criminal justice system and the civil justice system. The criminal justice system deals with crimes against society as a whole, while the civil justice system deals with disputes between individuals or organizations.

### Questions and Answers

**Question:** What is the difference between the criminal and civil justice systems?

**Answer:** The criminal justice system deals with crimes against society as a whole, while the civil justice system deals with disputes between individuals or organizations. In the criminal justice system, the government prosecutes individuals who are accused of breaking the law, while in the civil justice system, individuals or organizations bring lawsuits against others who they believe have harmed them.

**Question:** What are the different components of the criminal justice system?

**Answer:** The criminal justice system includes law enforcement, the courts, and corrections. Law enforcement officers are responsible for investigating crimes and making arrests. The courts are responsible for trying and sentencing individuals who are accused of crimes. Corrections officers are responsible for supervising and rehabilitating individuals who have been convicted of crimes.

**Question:** What are the different components of the civil justice system?

**Answer:** The civil justice system includes the courts and alternative dispute resolution methods such as mediation and arbitration. In the courts, individuals or organizations can bring lawsuits against others who they believe have harmed them. Alternative dispute resolution methods involve working with a neutral third party to reach a resolution without going to court.

## Section 3: Key Legal Doctrines

There are several key legal doctrines that are essential to understanding the American justice system. These include the burden of proof, the presumption of innocence, and the right to a fair trial.

### Questions and Answers

**Question:** What is the burden of proof?

**Answer:** The burden of proof is the responsibility of proving a claim or allegation. In the criminal justice system, the prosecution has the burden of proving beyond a reasonable doubt that the defendant committed a crime. In the civil justice system, the plaintiff has the burden of proving their case by a preponderance of the evidence.

**Question:** What is the presumption of innocence?

**Answer:** The presumption of innocence is a legal principle that requires the prosecution to prove a defendant guilty beyond a reasonable doubt. It means that individuals are considered innocent until proven guilty and are entitled to a fair trial.

**Question:** What is the right to a fair trial?

**Answer:** The right to a fair trial is a fundamental principle of the American justice system. It guarantees that individuals will be treated fairly and impartially, and that they will have the opportunity to present evidence and make their case. This right includes the right to an impartial judge, the right to a jury trial, and the right to effective assistance of counsel.

## Conclusion

In conclusion, the American justice system is a complex network of laws, institutions, and procedures that work together to maintain order and ensure fairness in society. By understanding the basics of the system, including its history, structure, and key players, we can better understand our role in the justice process and how to apply the skills gained from this lesson to new problems.

text: Abstract. Fluorescence spectroscopy has been used to investigate the conformational changes that occur upon binding of wild type (WT) and mutant (Thr123Ile) lecithin:cholesterol acyltransferase (LCAT) to the potential substrates (dioleoyl-phosphatidyl choline [DOPC] and high density lipoprotein [HDL]). For a detailed analysis of structural differences between WT and mutant LCAT, we performed decompositional analysis of a set of tryptophan fluorescence spectra, measured at increasing concentrations of external quenchers (acrylamide and KI). The data obtained show that Thr123Ile mutation in LCAT leads to a conformation that is likely to be more rigid (less mobile/flexible) than that of the WT protein with a redistribution of charged residues around exposed tryptophan fluorophores. We propose that the redistribution of charged residues in mutant LCAT may be a major factor responsible for the dramatically reduced activity of the enzyme with HDL and reconstituted high density lipoprotein (rHDL).

Lesson: Introduction to Fluorescence Spectroscopy

Fluorescence spectroscopy is a technique used to study the properties of molecules by measuring the light they emit when they absorb energy from a source. In this lesson, we will learn about the basics of fluorescence spectroscopy, its applications, and how it can be used to study the structure and function of proteins.

**Section 1: What is Fluorescence Spectroscopy?**

Fluorescence spectroscopy is a method that measures the light emitted by molecules that have absorbed energy from an external source. When a molecule absorbs energy, it enters an excited state, and then releases the excess energy as light when it returns to its ground state. This process is called fluorescence.

**Section 2: How does Fluorescence Spectroscopy work?**

Fluorescence spectroscopy works by shining a light source onto a sample containing fluorescent molecules. The light source excites the molecules, causing them to absorb energy and enter an excited state. As the molecules return to their ground state, they emit light, which is detected by a spectrometer. The spectrometer measures the wavelength and intensity of the emitted light, producing a spectrum that can be analyzed to determine the properties of the molecules.

**Section 3: Applications of Fluorescence Spectroscopy**

Fluorescence spectroscopy has many applications in fields such as chemistry, biology, and materials science. It can be used to study the structure and function of proteins, identify and quantify molecules in complex mixtures, and detect and analyze trace amounts of contaminants in environmental samples.

**Section 4: Studying Proteins with Fluorescence Spectroscopy**

Fluorescence spectroscopy can be used to study the structure and function of proteins by analyzing the changes in their fluorescence properties upon binding to other molecules or undergoing conformational changes. This technique is particularly useful for studying proteins that are difficult to work with using other techniques, such as those that are sensitive to light or have low solubility.

**Section 5: Conclusion**

In this lesson, we have learned about fluorescence spectroscopy, how it works, and its applications in studying proteins. By understanding the principles of this technique, we can gain valuable insights into the structure and function of proteins, leading to advances in our knowledge of biological systems and the development of new therapeutic strategies.

The efficacy of tamoxifen in estrogen receptor-positive breast cancer cells is enhanced by a medical nutriment.
Avemar, a fermented wheat germ extract, has been applied in the supplementary therapy of human cancers. Because tamoxifen is commonly used in the therapy of ER+ breast cancer, in this study the combined effect of tamoxifen and Avemar treatment was investigated on MCF-7 breast cancer cells, in order to detect a possible agonistic or antagonistic action. Cytotoxicity was measured by MTT assay, the percentage of mitoses and apoptotic cells was determined morphologically, apoptosis and S-phase was measured by flow cytometry, and estrogen-receptor activity was determined by semiquantitative measurement of the estrogen-responsive pS2 gene mRNA production. Tamoxifen (1 nM) alone had no effect on the percentage of the apoptotic cell fraction and significantly reduced the percentage of the S-phase, compared to untreated cells. Avemar (625 microg/mL) significantly increased apoptosis after 48 hours of treatment. Tamoxifen together with Avemar significantly increased apoptosis already 24 hours after starting treatment but had only a slight (not significant) effect on mitosis and S-phase. Estrogen-receptor activity of MCF-7 cells was enhanced by Avemar, decreased by tamoxifen, and was further decreased by combined tamoxifen and Avemar treatment. As apoptosis increased when Avemar was added to tamoxifen treatment, the use of supplementary therapy with Avemar in the case of ER+ breast tumors may enhance the therapeutic effects of tamoxifen.

Lesson: Introduction to Cancer Treatment

### Chapter 1: What is Cancer?
Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. It can affect almost any part of the body and is usually named after the type of cell it affects, such as lung cancer or breast cancer.

### Chapter 2: How does Cancer Treatment Work?
Cancer treatment aims to cure cancer, control its growth, or relieve symptoms. There are several types of treatments available, including surgery, radiation therapy, chemotherapy, hormone therapy, and immunotherapy. These treatments work in different ways to attack cancer cells or help the body fight them.

### Chapter 3: Tamoxifen and Avemar in Breast Cancer Treatment
In this study, researchers investigated the combined effect of tamoxifen and Avemar treatment on MCF-7 breast cancer cells. Tamoxifen is a common drug used to treat estrogen-receptor positive breast cancer, while Avemar is a fermented wheat germ extract that has been used as a supplementary therapy for human cancers.

### Chapter 4: Results of the Study
The results showed that tamoxifen alone had no effect on the percentage of apoptotic cell fractions and significantly reduced the percentage of the S-phase compared to untreated cells. Avemar significantly increased apoptosis after 48 hours of treatment. When used together, tamoxifen and Avemar significantly increased apoptosis already 24 hours after starting treatment but had only a slight (not significant) effect on mitosis and S-phase.

### Chapter 5: Conclusion
This study suggests that the combination of tamoxifen and Avemar may be more effective in treating estrogen-receptor positive breast cancer than tamoxifen alone. Further research is needed to determine the optimal dosage and duration of treatment for this combination therapy.

### Glossary
- Apoptosis: The process of programmed cell death
- S-phase: The phase of the cell cycle when DNA replication occurs
- Estrogen-receptor: A protein that binds to estrogen and regulates the growth of certain cells
- Tamoxifen: A drug used to treat estrogen-receptor positive breast cancer
- Avemar: A fermented wheat germ extract used as a supplementary therapy for human cancers

### Conclusion
This lesson introduced the concept of cancer treatment and discussed the use of tamoxifen and Avemar in the treatment of estrogen-receptor positive breast cancer. Students learned about the basic principles of cancer treatment and the specifics of this particular study. They also learned about the importance of further research to determine the optimal dosage and duration of treatment for this combination therapy.

Title: Understanding Endorsements and Their Impact on Elections

Introduction:
Endorsements play a crucial role in elections as they help candidates gain recognition, support, and credibility among voters. In this lesson, we will explore what endorsements are, why they matter, and how they can impact the outcome of an election.

Section 1: What is an Endorsement?
An endorsement is a public show of support or approval for a person or product. In the context of politics, an endorsement is when a group or individual publicly supports a candidate for office.

Section 2: Why do Endorsements Matter?
Endorsements matter because they can influence voter behavior. When a respected organization or individual endorses a candidate, it can increase the candidate's credibility and appeal to potential supporters. Endorsements can also help candidates raise money, gain media attention, and mobilize supporters.

Section 3: Types of Endorsements
There are several types of endorsements that candidates can receive, including:

1. Political endorsements: These are endorsements from other politicians, political parties, or organizations.
2. Celebrity endorsements: These are endorsements from famous individuals who use their platform to support a candidate.
3. Expert endorsements: These are endorsements from experts in a particular field who can provide insight into a candidate's qualifications.
4. Grassroots endorsements: These are endorsements from ordinary citizens who support a candidate based on their platform and values.

Section 4: Impact of Endorsements on Elections
Endorsements can have a significant impact on elections, particularly in close races where every vote counts. In some cases, an endorsement can be the difference between winning and losing an election. However, endorsements are not always predictive of election outcomes, as voters may have different priorities and values than the groups or individuals making the endorsements.

Section 5: Critical Thinking Questions
1. Why do you think endorsements are important in elections?
2. Can you think of any examples of successful or unsuccessful endorsements in recent elections?
3. How might an endorsement from a group or individual you disagree with impact your decision to support a candidate?

Conclusion:
Endorsements play a crucial role in politics by providing candidates with support, credibility, and visibility. While endorsements are not always predictive of election outcomes, they can be influential in swaying voters to support a particular candidate. As critical thinkers, it is essential to consider the source of the endorsement and evaluate its validity in relation to our personal values and beliefs. By doing so, we can make informed decisions when casting our votes.

Glossary:
- Endorsement: A public show of support or approval for a person or product.
- Candidate: A person seeking election to a particular office.
- Credibility: The quality of being trustworthy and reliable.
- Validity: The quality of being accurate or true.

Lesson: How to Read and Understand News Articles

Introduction:
 Reading news articles is an essential skill that helps us stay informed about current events and understand the world around us. In this lesson, we will learn how to read and understand news articles by breaking them down into their main components.

Section 1: Understanding the Structure of a News Article

A typical news article has several key components, including:

- Headline: This is the title of the article, which summarizes the main idea in a few words.
- Lead: This is the first sentence of the article, which introduces the topic and provides some background information.
- Body: This section contains the main details of the story, including quotes from sources and any relevant data or statistics.
- Conclusion: This is the last paragraph of the article, which wraps up the story and may provide some final thoughts or analysis.

As you read through a news article, pay close attention to these components and try to understand how they fit together to convey the overall message of the story.

Section 2: Identifying the Main Idea and Supporting Details

Once you have a basic understanding of the structure of a news article, you can start to focus on identifying the main idea and supporting details. The main idea is the central point of the story, while the supporting details are the specific facts and examples that help to explain and illustrate this main idea.

To identify the main idea, look for the lead paragraph, which should provide some context and set the stage for the rest of the story. As you read through the body of the article, look for any quotes, statistics, or other pieces of evidence that support the main idea. Finally, check the conclusion to see if there are any final thoughts or insights that help to clarify the story's message.

To practice identifying the main idea and supporting details, try reading through the following news article:

[Insert news article here]

Section 3: Analyzing the Author's Perspective and Bias

Even though news articles are supposed to be objective and factual, it's important to recognize that every author has their own perspective and bias. This means that the way they present information and the choices they make in terms of what to include or leave out can reflect their personal beliefs and values.

To analyze the author's perspective and bias, consider the following questions:

- Who is the author? What is their background and experience, and how might this influence their perspective on the topic?
- What sources are cited in the article? Are they reliable and credible, or do they have a particular agenda or bias?
- What language and tone is used in the article? Are there any loaded words or phrases that suggest a particular viewpoint?

By considering these factors, you can begin to understand the author's perspective and how it may affect the overall message of the article.

Section 4: Practicing Critical Thinking Skills

Finally, as you read and analyze news articles, it's important to practice critical thinking skills. This means asking questions, evaluating evidence, and drawing conclusions based on the available information.

To practice critical thinking, try answering the following questions:

- What are the main arguments or points being made in the article?
- Are these arguments supported by evidence or data, or are they based on opinion or speculation?
- What assumptions or assumptions are being made in the article? Are these valid or supported by the available evidence?
- How might the information in the article be interpreted or used by different people or groups?

By engaging in these types of questions and analysis, you can develop a deeper understanding of the news article and the issues it raises.

Conclusion:
In this lesson, we have learned how to read and understand news articles by analyzing their structure, identifying the main idea and supporting details, and considering the author's perspective and bias. By practicing critical thinking skills, we can become more informed and engaged citizens who can make sense of the world around us.

Q:

The number $2^{3^n}+1$ is divisible by $3^{n+1}$ and not divisible by $3^{n+2}$.

Prove that for every $n\in \mathbb N$, $2^{3^n}+1$ is divisible by $3^{n+1}$ and not divisible by $3^{n+2}$.

I was able to prove that $2^{3^n}+1$ is divisible by $3^{n+1}$ using induction.
First, I check whether the statement is true for $n=1$. The statement holds since:
$$2^{3^1}+1=9$$ $$3^{1+1}=9$$
Second, I assume that the statement is true for every $n\in \mathbb N$.
Finally, I take that $n=n+1$. From that, the original expression becomes $(2^{3^n})^3+1$, which is a sum of cubes, and the same as:
$$(2^{3^n}+1)((2^{3^n})^2-2^{3^n}+1)$$
As I assumed that $2^{3^n}+1$ is divisible by $3^{n+1}$, and one of the factors is $2^{3^n}+1$, the entire expression must be divisible by $3^{n+1}$, and so the statement is true for every $n\in \mathbb N$.
Now, I don't know how to prove that $2^{3^n}+1$ isn't divisible by $3^{n+2}$. Please explain how I can do so step-by-step, without using complicated terms.

A:

Let
$$A_n = 2^{3^n}+1.$$
The claim holds for $n=0$, and since:
$$ A_{n+1} = (A_n-1)^3+1 = A_n^3 -3A_n(A_n-1) $$
we have that $\nu_3(A_{n+1}) = 1+\nu_3(A_n)$, since $9\mid A_n^3$ and $3\mid 3A_n$ but $3\nmid (A_n-1)$.

textbook:
Sure, I'd be happy to help you with that!

To prove that $2^{3^n}+1$ is not divisible by $3^{n+2}$, we need to show that there exists some $n\in \mathbb N$ such that $2^{3^n}+1$ is not divisible by $3^{n+2}$.

Let's consider the expression $2^{3^n}+1$. We can rewrite this as:
$$2^{3^n}+1 = 3^n + 2^{3^n} - 1$$

Now, let's look at the expression $3^{n+2}$. We can rewrite this as:
$$3^{n+2} = 3(3^n) = 3^n \cdot 3$$

Notice that if $2^{3^n}+1$ were divisible by $3^{n+2}$, then it would mean that there exists some integer $k$ such that:
$$2^{3^n}+1 = k \cdot 3^n \cdot 3$$

However, this is not possible because $2^{3^n}+1$ is an odd number (it is a sum of an even number and an odd number), while $3^n \cdot 3$ is an even number. Therefore, no such integer $k$ exists.

Thus, we have shown that $2^{3^n}+1$ is not divisible by $3^{n+2}$, and we have completed the proof.

In summary, we used mathematical induction to prove that $2^{3^n}+1$ is divisible by $3^{n+1}$, and we showed that it is not divisible by $3^{n+2}$ by contradicting the assumption that it is divisible by an even number.

Product review: lucis image processing software.
Lucis is a software program that allows the manipulation of images through the process of selective contrast pattern emphasis. Using an image-processing algorithm called Differential Hysteresis Processing (DHP), Lucis extracts and highlights patterns based on variations in image intensity (luminance). The result is that details can be seen that would otherwise be hidden in deep shadow or excessive brightness. The software is contained on a single floppy disk, is easy to install on a PC, simple to use, and runs on Windows 95, Windows 98, and Windows NT operating systems. The cost is $8,500 for a license, but is estimated to save a great deal of money in photographic materials, time, and labor that would have otherwise been spent in the darkroom. Superb images are easily obtained from unstained (no lead or uranium) sections, and stored image files sent to laser printers are of publication quality. The software can be used not only for all types of microscopy, including color fluorescence light microscopy, biological and materials science electron microscopy (TEM and SEM), but will be beneficial in medicine, such as X-ray films (pending approval by the FDA), and in the arts.
