I'm a little worried I paid to much for my first setup but it rides really good to me.. A Raleigh Capri 19-80's 410 steel with suntour comps.. I got it for $200 but the guy had new tires, chain, and cleaned the bearings and everything so its like new I think. The guy fixes a lot of bikes and I liked him so I figured what the hell.. I did some research and I know its not the best bike, but it feels good and I rode a bunch he had like old schwins and nishiki and univegas, but this one felt the best and had double breaks on the top handle and down turns which I like.. What do you guys think?. Did I get ripped or is it ok. I've seen them for as much as 300 when I looked around and old ****y ones for about 50 but mines clean and kills 40 miles no problem. I also like the heavier steel cause I'm about two hundread pounds and it feels sturdy.

Effects of the dual endothelin receptor antagonist tezosentan and hypertonic saline/dextran on porcine endotoxin shock.
To evaluate the haemodynamic effects of the dual endothelin receptor antagonist tezosentan, both alone and combined with hypertonic saline/dextran (HSD), on porcine endotoxin shock, with focus on cardiopulmonary circulation. The effects on gas exchange and short-term survival were also studied. A prospective, randomized experimental study was carried out. Thirty-two anaesthetized pigs underwent pulmonary and carotid artery catheterization. Following haemodynamic stabilization and baseline measurements, endotoxaemia was induced by an Escherichia coli-endotoxin infusion over 180 min and the animals observed another 120 min. After 60 min of endotoxaemia, directly before intervention, animals were randomized into four groups: a tezosentan group, an HSD group, a combined tezosentan/HSD group and a control group. The consequent haemodynamic effects and blood gas results were recorded. The endotoxin infusion reduced mean arterial blood pressure from 111 +/- 14 (mean +/- standard deviation) to 77 +/- 27 mmHg and cardiac index from 126.9 +/- 27.2 to 109.3 +/- 22.6 mL min(-1) kg(-1) within 90 min in the control group. In addition, endotoxin simultaneously increased mean pulmonary artery pressure from 24 +/- 17 to 38 +/- 19 mmHg and reduced arterial oxygenation from 18.9 +/- 2.0 to 12.2 +/- 5.3 kPa. Tezosentan, alone and combined with HSD, reversed the pulmonary hypertension and prevented the reduction in cardiac index and arterial oxygenation, resulting in reduced metabolic acidosis. Additionally, in the tezosentan group, the mean arterial blood pressure was reduced to the same level as in controls, an effect not prevented by the addition of HSD. It was found that all three interventions improved survival rates. Tezosentan, alone and in combination with HSD, improved cardiac index and arterial oxygenation. The addition of HSD to tezosentan treatment did not improve the endotoxin-induced hypotension, but beneficial effects on microcirculation and systemic oxygenation were seen despite low perfusion pressure, as indicated by increased SvO(2) and reduced metabolic acidosis.

Lesson: Understanding the Effects of Endotoxin Shock on Cardiopulmonary Circulation

Introduction:
Endotoxin shock is a life-threatening condition that occurs when the body is exposed to high levels of endotoxins, such as those found in Escherichia coli bacteria. This can lead to severe inflammation, organ failure, and even death. Understanding the effects of endotoxin shock on cardiopulmonary circulation is crucial for developing effective treatments.

Objective:
The objective of this lesson is to provide a basic understanding of the effects of endotoxin shock on cardiopulmonary circulation, with a focus on the haemodynamic effects, gas exchange, and short-term survival.

Section 1: Haemodynamic Effects

Endotoxin shock causes a range of haemodynamic changes, including:

1. Vasodilation: Endotoxins cause vasodilation, which means that blood vessels widen, leading to a decrease in blood pressure.

2. Increased cardiac output: The heart has to work harder to pump blood through the dilated blood vessels, resulting in an increase in cardiac output.

3. Decreased systemic vascular resistance: The blood vessels become more permeable, allowing fluid to leak into the surrounding tissue, leading to a decrease in systemic vascular resistance.

4. Increased pulmonary capillary wedge pressure: The increased hydrostatic pressure in the blood vessels can cause fluid to accumulate in the lungs, leading to pulmonary oedema.

Section 2: Gas Exchange

Endotoxin shock can also affect gas exchange, leading to:

1. Hypoxemia: The body's tissues do not receive enough oxygen due to the leakage of fluid into the lungs, making it difficult for the lungs to function properly.

2. Acidosis: The buildup of lactic acid and other metabolic waste products can lead to a decrease in blood pH, causing acidosis.

Section 3: Short-Term Survival

The severity of endotoxin shock can vary, but it is generally associated with a poor prognosis. Some potential outcomes include:

1. Multi-organ dysfunction: The widespread inflammation caused by endotoxin shock can lead to damage to multiple organs, including the liver, kidneys, and lungs.

2. Septic shock: If the body's immune response to the endotoxin becomes overwhelming, it can lead to septic shock, a life-threatening condition characterized by dangerously low blood pressure, organ failure, and a high risk of death.

Conclusion:
Understanding the effects of endotoxin shock on cardiopulmonary circulation is essential for developing effective treatments. By studying the haemodynamic effects, gas exchange, and short-term survival, researchers can gain valuable insights into the mechanisms behind this life-threatening condition and work towards improving patient outcomes.

Glossary:
- Endotoxin: a toxic substance found in the cell walls of certain bacteria, such as Escherichia coli
- Vasodilation: the widening of blood vessels, which can lead to a decrease in blood pressure
- Cardiac output: the amount of blood pumped by the heart per minute
- Systemic vascular resistance: a measure of how easily blood flows through the blood vessels
- Pulmonary capillary wedge pressure: the pressure that forces fluid into the lungs
- Hypoxemia: a condition where the body's tissues do not receive enough oxygen
- Acidosis: a condition where the blood pH is too low, causing an excess of hydrogen ions
- Multi-organ dysfunction: damage to multiple organs due to inflammation
- Septic shock: a life-threatening condition characterized by dangerously low blood pressure, organ failure, and a high risk of death.

Nassim Taleb, scourge of the banking sector, has a new target: orange juice
(an unhealthy cocktail of sugars). In fact, breakfast gets a mauling. And
trainers (the shoes and the fitness “gurus”). Be prepared. You will have to
engage with the crisis of capitalism alongside homespun injunctions: wear
sock-style shoes to mimic walking barefoot; “just drink wine, water and
coffee”; exercise isn’t enough, get hungry through fasting.

The central thesis of Antifragile: How to Live in a World We Don’t
Understand is easy enough to summarise. What is the opposite of
fragility? It is not quite robustness because there is

textbook:
# Lesson: Core Value - Antifragile
## Introduction
In this lesson, we will explore the concept of antifragile, which refers to systems or entities that gain strength and resilience from adversity, uncertainty, and chaos. This concept was introduced by Nassim Nicholas Taleb in his book "Antifragile: How to Live in a World We Don't Understand." We will examine how this idea can be applied to various aspects of life, including finance, health, and personal growth.

## Section 1: What is Antifragile?
### Question: What does the term "antifragile" mean?
Answer: Antifragile refers to systems or entities that become stronger and more resilient when exposed to adversity, uncertainty, and chaos.

### Question: How is antifragile different from robustness?
Answer: While robustness refers to systems that are resistant to change and remain stable under normal conditions, antifragile systems gain strength and resilience from adversity, uncertainty, and chaos.

### Question: Can you provide an example of an antifragile system?
Answer: One example of an antifragile system is the human immune system, which becomes stronger and more resilient when exposed to pathogens and other foreign substances.

## Section 2: Applications of Antifragile
### Question: How can the concept of antifragile be applied to finance?
Answer: In finance, antifragile systems can be designed to withstand and even benefit from market volatility and uncertainty. For example, investors can diversify their portfolios to reduce risk and increase resilience in the face of market fluctuations.

### Question: How can the concept of antifragile be applied to health?
Answer: In health, antifragile systems can be applied by engaging in regular physical activity, intermittent fasting, and consuming a diet rich in whole foods and nutrients. These practices can help the body become stronger and more resilient to disease and illness.

### Question: How can the concept of antifragile be applied to personal growth?
Answer: In personal growth, antifragile systems can be applied by embracing challenges, seeking out new experiences, and learning from mistakes. By doing so, individuals can become stronger and more resilient in the face of adversity and uncertainty.

## Section 3: Examples of Antifragile Systems
### Question: Can you provide an example of an antifragile system in nature?
Answer: One example of an antifragile system in nature is the forest ecosystem, which becomes stronger and more resilient after a wildfire. The fire clears out dead vegetation and makes way for new growth, ultimately leading to a healthier and more diverse ecosystem.

### Question: Can you provide an example of an antifragile system in technology?
Answer: One example of an antifragile system in technology is the software development process, which can be designed to learn from and adapt to errors and bugs. By incorporating feedback loops and continuous improvement processes, software developers can create systems that become stronger and more resilient over time.

## Conclusion
In this lesson, we have explored the concept of antifragile and its applications in finance, health, and personal growth. We have also examined examples of antifragile systems in nature, technology, and other areas. By understanding and applying the principles of antifragile systems, individuals and organizations can become stronger, more resilient, and better equipped to navigate the uncertainties of the future.


text: converts a source program into intermediate code. The computer detects, based on profile information related to a memory access for accessing target data stored in a memory, a memory access that fits an access pattern corresponding to an operating condition of a hardware prefetch function for the target data. The target data is data for which a prefetch instruction is to be inserted in advance. The prefetch instruction is an instruction for transferring data stored in the memory to a cache memory. The computer computes an evaluation value for the target data based on a length of successive memory accesses that fit the access pattern, and determines, based on the evaluation value, whether to suppress insertion of a prefetch instruction for the target data. The computer updates the intermediate code based on a result of the determination, and converts the updated intermediate code into a machine language program.

text: I saw a new head teacher client this week and had a great discussion around openness and stepping into the unknown of non-evidence based projects and policies.. Of course there’s a reality of a framework that needs to be adhered to for Ofsted and strategy, but what if we get into more rigid patterns or indeed positions of stalemate?. What if we believe we need to see evidence all the time before we move forward into the unknown? Learning is unknown isn’t it? For me the wonder and magic of learning is the very fact that it’s held beautifully in the unknown.. We may hesitate, get scared, hold back or jump in – not from a creative place but from a fear of what’s gone before. What if that previous experience we had happens again? How could we forgive ourselves?. What may be lost in the fear of before is an authentic openness to the here and now. Creating a new path of possibility rather than a fearful path of prevention.. That sounds exciting!. Are you steering your leadership from creativity or fear?

You cannot enforce a ceasefire without cutting off weapons and ammo supplies

[ Editor’s Note: This Tillerson statement is a hoot, that Russia has a “special responsibility” to aid the peace process in Syria, when he knows that if the Russians had not come in, the jihadis would have won, and we would have a mess 50 times bigger than Libya.

That’s the one where Obama at least admitted that not making plans for what to do to stabilize Libya after Saddam was “a mistake”. But how was he supposed to know that? The US has never worried about what happens afterwards, as the Deep State folks figure they have won, and the exploiting of the country will move into the bone-picking stage.

With Iraq, they just fired the army and police, so there was instantly no security in the country, and a looting frenzy began. That was not something that would have taken a genius to foresee, but we did it anyway. Based on its horrible record, in a perfect world, the US would never be allowed to intervene anywhere. Where are the ETs when you really need them?

This no-fly zone pitch by Tillerson…color me suspicious. I suspect that he knows the US and its Gulf State allies are going to maintain weapons and ammo supplies to their jihadi proxies, and that Russia will bomb those convoys and depots when and where it can.

Don’t hold your breath on anything that is said in Hamburg between Putin and Trump on Syria. If Trump deems it profitable for him to appear conciliatory, he will be, knowing he can still do whatever he wants later, muttering something about “America first”. Because the master of chaos lives inside his head, that is what we get. We got a two for one deal with Trump, and have at least three and a half years more of it to survive… Jim W. Dean ]

Any eventual control over reducing the fighting in Syria will require blocking supplies of weapons and ammo by the US and allies to their terror proxies

– First published … July 07, 2017 –

–

Moscow has noted Washington’s apparent move in the right direction on Syria, but has requested the US to provide details on the proposed creation of no-fly zones as voiced by US Secretary of State in the lead up to the Russian-US leaders meeting in Hamburg.

Ahead of the July 7 meeting between Vladimir Putin and Donald Trump, chief US diplomat, Rex Tillerson insisted that Russia has a “special responsibility” to aid the peace process in Syria, while Washington expressed a readiness for closer cooperation with Moscow.

“The United States is prepared to explore the possibility of establishing with Russia joint mechanisms for ensuring stability, including no-fly zones, on the ground ceasefire observers, and coordinated delivery of humanitarian assistance,” Rex Tillerson said in a statement released by the State Department Wednesday.

Speaking to reporters Thursday, Russian Foreign Minister Sergey Lavrov said Moscow is awaiting Washington’s concrete suggestions and clarifications on the the no-fly zones in Syria.

“We’ve issued a query but haven’t received a reply so far,” Lavrov said, according to TASS. “The question is what kind of no-flight zones are being presupposed because they haven’t been mentioned in the past.”

Lavrov pointed that Moscow is also still waiting for a response to its own proposals on Syria which were presented to the Americans in spring.

“We handed our proposals timed for the first contact between the Russian and US Presidents to US Secretary of State Rex Tillerson before his trip to Moscow in April,” Lavrov said.

“This was because he himself had come up with an idea of preparations for the meeting between the Presidents in advance when we had talks in Bonn in February.”

The Russian Foreign Minister welcomed his counterpart’s initiative. “I am confident that the focus of [Tillerson’s] statement, despite all the emerging issues on this or that wording, the determination on cooperation between Russia and the United States, is a step in the right direction,” Lavrov told reporters after talks with French Foreign Minister Jean-Yves Le Drian in Paris.

“It is important for the Syrian crisis settlement to be mutual, with no party trying to pretend that nothing depends on them,”Russia’s most senior diplomat added. Russia’s main priority in Syria, though, is to eliminate terrorist groups, mainly the Islamic State (IS, formerly ISIS/ISIL) and Jabhat al-Nusra, Lavrov underlined.

Syria already has three de-escalation zones after Russia, Turkey, and Iran signed a deal in Astana, Kazakhstan in May. While the specifics of the newly created safe zones are now being worked out, the concept envisions ceasing all combat operations and suspending military flights in those areas.

However, the US-led coalition has used the opportunity to establish their own so-called ‘de-confliction’ areas, within which, it has on several occasions, used perceived threats to allies as a pretext to strike Syrian government forces.

Moscow does not recognize any ‘de-confliction zones’ unilaterally declared by the US. Lavrov has made clear that such zones are different from the safe zones, which Russia, Turkey, and Iran established with the full support of the United Nations Security Council and the government of Syria.

Lesson: How to Analyze a Political Statement

### Overview

In this lesson, we will learn how to analyze a political statement by breaking it down into its key components. We will use the statement "You cannot enforce a ceasefire without cutting off weapons and ammo supplies" as an example.

### Section 1: Understanding the Key Components

A political statement typically consists of three key components: the subject, the verb, and the object. In our example statement, the subject is "You," the verb is "cannot," and the object is "enforce a ceasefire."

- **Subject:** The subject is the person or entity that is performing the action in the statement. In this case, the subject is "You," which refers to a general you, rather than a specific person.
- **Verb:** The verb is the action that the subject is performing. In this case, the verb is "cannot," which indicates that the subject is unable to perform the action.
- **Object:** The object is the thing that is being acted upon by the subject. In this case, the object is "enforce a ceasefire," which means that the subject is unable to ensure that a ceasefire is being followed.

### Section 2: Analyzing the Statement

Now that we understand the key components of the statement, let's break it down further to analyze its meaning.

- **Ceasefire:** A ceasefire is a temporary cessation of hostilities between two warring parties. It is usually declared as a first step towards negotiating a peace treaty.
- **Enforce:** To enforce something means to make sure that it is obeyed or done. In the context of a ceasefire, this means ensuring that both sides are adhering to the agreement and refraining from fighting.
- **Weapons and ammo supplies:** Weapons and ammo supplies refer to the guns, bullets, and other military equipment used in a conflict.

Putting it all together, the statement is saying that in order to ensure that a ceasefire is being observed, it is necessary to prevent the flow of weapons and ammunition to the combatants. Without this, it will be impossible to enforce the ceasefire and maintain peace.

### Section 3: Applying the Skill

Now that we have analyzed the statement, let's apply the skill to a real-world scenario. Imagine that you are a diplomat tasked with negotiating a ceasefire between two warring factions. You know that in order to enforce the ceasefire, you must prevent the flow of weapons and ammunition to the combatants. How would you go about achieving this?

One possible solution could be to establish a United Nations-backed arms embargo, which would prohibit the shipment of weapons and ammunition to either side. Additionally, you could propose the deployment of international observers to monitor the ceasefire and report any violations to the UN Security Council.

In conclusion, by analyzing a political statement, we can gain a deeper understanding of the issues at hand and develop effective solutions. By applying this skill, we can contribute to the peaceful resolution of conflicts and promote global stability.

Lesson: Privacy and Confidentiality in Healthcare

Introduction:
Privacy and confidentiality are crucial aspects of any doctor-patient relationship. As a healthcare professional, it is essential to understand the importance of protecting patient information and maintaining their privacy. In this lesson, we will explore the reasons why privacy and confidentiality are vital in healthcare, and we will discuss the implications of breaching patient privacy.

Core Value:
The core value of this lesson is to emphasize the importance of protecting patient privacy and maintaining confidentiality in healthcare.

Section 1: Why is Privacy and Confidentiality Important in Healthcare?

Topic 1: Legal and Ethical Obligations
Healthcare professionals are bound by legal and ethical obligations to protect patient privacy and maintain confidentiality. Failure to do so can result in severe consequences, including legal action, loss of license, and damage to reputation.

Topic 2: Building Trust
Patients need to trust their healthcare providers to share personal and sensitive information. If patients do not trust their doctors, they may not disclose essential information, which can affect diagnosis and treatment.

Topic 3: Maintaining Patient Dignity
Respecting patient privacy and maintaining confidentiality helps maintain patient dignity. Patients have the right to privacy and should not be made to feel uncomfortable or embarrassed during consultations.

Section 2: Implications of Breaching Patient Privacy

Topic 1: Legal Consequences
Breaching patient privacy can have severe legal consequences. Depending on the jurisdiction, healthcare professionals may face fines, lawsuits, or even criminal charges.

Topic 2: Damage to Reputation
A breach of patient privacy can damage a healthcare professional's reputation. The news of such a breach can spread quickly, leading to loss of trust from patients and peers.

Topic 3: Loss of Employment
In some cases, breaching patient privacy can lead to loss of employment. Healthcare organizations have zero-tolerance policies for privacy breaches, and employees found guilty may be fired.

Section 3: Practical Examples

Topic 1: Storing Patient Records
Patient records must be stored securely and accessed only by authorized personnel. Electronic records should be encrypted, and physical records should be locked away when not in use.

Topic 2: Recording Consultations
Recording consultations without the patient's knowledge or consent is a breach of privacy. However, some healthcare professionals may record consultations with the patient's consent, especially in cases where the patient is unable to give informed consent.

Topic 3: Sharing Patient Information
Patient information should only be shared with authorized personnel who require it for clinical care. Healthcare professionals should never share patient information without a valid reason or without the patient's consent.

Conclusion:
Protecting patient privacy and maintaining confidentiality is essential in healthcare. Healthcare professionals must understand the legal and ethical implications of breaching patient privacy and take steps to prevent such breaches. By doing so, healthcare professionals can build trust with their patients and provide high-quality care.

Glossary:
- Privacy: The right to be left alone or to be free from intrusion or disturbance.
- Confidentiality: The duty to keep information private and only share it with those who need to know it.
- Breach: A violation or failure to observe a law, rule, or standard.

Self-Debating Discussion:

Topic 1: Should healthcare professionals record consultations without the patient's knowledge or consent?
Arguments For: Recording consultations can help ensure accurate communication between the healthcare professional and the patient. It can also serve as evidence in case of malpractice claims.
Arguments Against: Recording consultations without the patient's knowledge or consent is a breach of privacy and trust. Patients may not feel comfortable discussing sensitive information if they know they are being recorded.

Topic 2: How can healthcare professionals ensure patient privacy and confidentiality when storing electronic records?
Arguments For: Electronic records should be encrypted to prevent unauthorized access. Access should be limited to authorized personnel only.
Arguments Against: Electronic records are vulnerable to hacking and cyber-attacks. Healthcare professionals must ensure that their electronic systems are up-to-date and secure.

Topic 3: How can healthcare professionals maintain patient privacy and confidentiality when accessing patient records?
Arguments For: Patient records should be accessed only when necessary and only by authorized personnel. Healthcare professionals should sign out when accessing patient records to ensure accountability.
Arguments Against: Patient records may be accessed by multiple healthcare professionals, increasing the risk of breach. Healthcare professionals must ensure that they follow protocols for accessing and sharing patient information.

Continuously recording refractive index spectrograph for transparent and opaque insulators and semiconductors.
An apparatus is described which enables the user to measure continuous refractive index spectra of opaque and transparent optically flat samples. The method of measurement is based on finding the Brewster's angle beta(B) of the sample. By modulating the angle of light incidence, the output signal of a lock-in amplifier, tuned to the modulation frequency, changes sign abruptly at beta(B). The lock-in signal is applied to a dc motor which drives a goniometer in that way that the sample is continually held at beta(B). Provided that the sample extinction coefficient k < or approximately 0.5, the accuracy of the refractive index measurements is better than 1%, or even 0.1% where k is approximately equal to 0.

textbook:
Lesson: How to Measure Refractive Index Spectra of Opaque and Transparent Materials

**Introduction**

In this lesson, we will learn about the method of measuring continuous refractive index spectra of opaque and transparent materials using an apparatus called a "continuously recording refractive index spectrograph." We will also learn about the principles behind this method and how it can be used to measure the refractive index of different materials accurately.

**Section 1: Theory**

The refractive index (n) of a material is a measure of how much the speed of light changes as it passes through that material. It is defined as the ratio of the speed of light in a vacuum (c) to the speed of light in the material (v): n = c/v. The refractive index is a crucial property of materials because it determines how light interacts with them, affecting phenomena such as reflection, refraction, and dispersion.

To measure the refractive index of a material, we need to know its extinction coefficient (k), which is a measure of how strongly the material absorbs light. The Beer-Lambert law relates the intensity of light transmitted through a material to its absorption coefficient (μ) and its path length (L): I = I₀ * exp(-μL), where I is the transmitted intensity and I₀ is the initial intensity. The extinction coefficient k is related to the absorption coefficient by k = √μ.

**Section 2: Practical Examples**

Now let's see how we can use the continuously recording refractive index spectrograph to measure the refractive index of different materials. Suppose we have a sample of glass with a known refractive index (n_glass). We can use the spectrograph to measure the refractive index of this glass and compare it to the known value. If the measured value is close to the known value, we can have confidence that our measurements are accurate.

Next, let's consider a sample of an unknown material (opaque or transparent) that we want to measure its refractive index. To do this, we first need to find its Brewster's angle (β_B). This is the angle at which the material reflects light most strongly. We can use the lock-in amplifier to find this angle by modulating the angle of light incidence and monitoring the output signal. Once we have found the Brewster's angle, we can hold the sample at this angle using the goniometer.

Finally, we can use the spectrograph to measure the refractive index of the unknown material by measuring the amount of light transmitted at different angles. By comparing these measurements to the known value of the glass, we can determine the accuracy of our measurements.

**Section 3: Critical Thinking**

As we saw in the practical examples, the accuracy of our measurements depends on the extinction coefficient of the material being measured. If the extinction coefficient is high (k > 0.5), we can achieve accuracy better than 1%. However, if the extinction coefficient is low (k ≈ 0), we can achieve accuracy better than 0.1%. This means that we need to choose the appropriate method for measuring the refractive index of different materials based on their extinction coefficients.

**Conclusion**

In this lesson, we learned about the principles behind measuring the refractive index of opaque and transparent materials using a continuously recording refractive index spectrograph. We also learned how to use the spectrograph to measure the refractive index of different materials and how to choose the appropriate method based on the material's extinction coefficient. By applying these skills, we can accurately measure the refractive index of various materials and use this information to understand how they interact with light.

Q:

which of the following is/are algebraic over rationals

which of the following is/are true?

$\sin 7^\circ$ is an algebraic over $\mathbb{Q}$
$\sin^{-1}(1)$ is algebraic over $\mathbb{Q}$
$\cos (\pi/7)$ is algebraic over $\mathbb{Q}$
$\sqrt{2}+\sqrt{\pi} $ is algebraic over $\mathbb{Q}(\pi)$

an algebraic number is a number that is a root of a non-zero polynomial in one variable with rational coefficients, I am perfectly sure that option $1$, $3$ are  algebraic number. could any one help me to find out others option?

A:

For option 2:
Evaluate $\sin^{-1}(1)$. It's easy
For $4$:
$\sqrt{2}+\sqrt{\pi}$ satisfies is a root of the equation:
$$(x^2-2-\pi)^2-2\pi=0$$
$$x^4-2(2+\pi)x^2+(\pi+2)^2-2\pi=0$$
$$x^4-(4+2\pi)x^2+\pi^2+2\pi+4=0$$
Hence $\sqrt{2}+\sqrt{\pi}$ is algebraic over $\mathbb{Q}(\pi)$

Here I will include the proofs of 2 useful facts:
Fact 1: Let $E$ be an extension field of a field $F$. Let $u\in E$. Then $u$
 is algebraic over $F$ iff $F(u)$ is finite dimesnsional over $F$.
Proof:
Forward direction: Consider the elements $1,u,u^2,...u^{[F(u):F]}$. If these $[F(u):F]+1$ elements were linearly independent over $F$, then the dimension of $F(u)$ over $F$ must be greater than or equal to $[F(u):F]+1$ (contradiction). Thus, we conclude that they are linearly dependent. Hence there exists $a_0,a_1,....,a_{[F(u):F]}\in F$ such that not all of thm are zero and:
$$a_{[F(u):F]}u^{[F(u):F]}+a_{[F(u):F]-1}u^{[F(u):F]-1}+...+a_1u+a_0=0$$
Hence $u$ is algebraic over $F$.
Backward direction: We start by showing that $F(u)=F[u]$. Clearly, $F[u]\subseteq F(u)$. Since $F(u)$ is the intersection of all subfields that contain $F\cup\{u\}$., therefore $F(u)\subseteq F[u]$ if $F[u]$. Now we verify that $F[u]$ is a field. Consider the  ring homomorphism $\phi: F[x]\rightarrow F(u)$ that sends $p(x)$ to $p(u)$. It can be shown that $\phi$ is surjective. Hence $F[u]\cong F[x]/Ker\phi$.    $Ker\phi=\{p(x)\in F[x]|p(u)=0\}$. Since $F$ is a field, therefore $F[x]$ is a PID. Since $Ker\phi$ is an ideal of $F[x]$, therefore $Ker\phi=(f(x))$ for some $f(x)\in F[x]$. It can be easily verified that $(f(u))$ is a prime ideal of $F[x]$. Since $F[x]$ is a PID, therefore $Ker\phi=(f(x))$ is a maximal ideal of $F[x]$. Hence $F[u]\cong F[x]/Ker\phi$ is a field. Thus $F(u)=F[u]$. Verify that $\{1,u,u^2,...,u^{deg(f)-1}\}$ is a basis for $F[u]$ over $F$. Hence, $F(u)=F[u]$ is a finite dimensional vector space over $F$.
Fact 2: Let $E$ be an extension field of a field $F$. Let $K:=\{x\in E|x$ is algebraic over$F\}$. Then $K$ is a field.
Proof: Let $x,y$ be algebraic over $F$. By fact 1, we deduce that $F(x)$ is finite dimensional over $F$. Since $y$ is algebraic over $F$, therefore $y$ is algebraic over $F(x)$. Thus, by fact 1 we deduce that $F(x)(y)$ is finite dimensional over $F(x)$. Since $F(x)$ is finite dimensional over $F$. Hence $F(x)(y)$ is finite dimensional over $F$. Since $x+y\in F(x)(y)$, therefore $F(x+y)$ is a subfield of $F(x)(y)$. Thus, $F(x+y)$ is finite dimensional over $F$. By fact 1, we deduce that $x+y$ is algebraic over $F$. Hence it is an element of $K$. The rest of the field axioms can be verified for $K$ similarly.

Since $\sqrt{2}$ is algebraic over $Q$, therefore it is algebraic over $Q[\pi]$. Similarly, $\sqrt{\pi}$ is algebraic over $\mathbb{Q}[\pi]$ (as it is the root of the equation $x^2-\pi=0$). Thus, we know that $\sqrt{2}+\sqrt{\pi}$ is algebraic over $\mathbb{Q}[\pi]$ by fact 2.

Examples of transcendental numbers include:
- π (pi)
- e (Euler's number)
- √2
- Any irrational number (e.g., √3, √5, √17)

Topic 2: Properties of Transcendental Numbers

Transcendental numbers have some interesting properties that make them useful in mathematics. For example:

1. The set of all transcendental numbers is uncountable, meaning that there are more transcendental numbers than there are natural numbers.
2. The decimal expansion of a transcendental number is non-terminating and non-repeating.
3. The operations of addition, subtraction, and multiplication of transcendental numbers are not closed, meaning that the sum, difference, or product of two transcendental numbers is not always transcendental.

Topic 3: Applications of Transcendental Numbers

Transcendental numbers are used in many different areas of mathematics, including:

1. Analysis: Transcendental numbers are used to study the behavior of real-valued functions and to analyze the properties of continuous functions.
2. Number theory: Transcendental numbers are used to study the properties of integers and rational numbers.
3. Algebra: Transcendental numbers are used to analyze the structure of algebraic systems and to study the behavior of polynomial equations.

Conclusion:

In this lesson, we learned about two types of numbers: algebraic numbers and transcendental numbers. We learned about their definitions, properties, and applications in mathematics. We also saw how these numbers are used in different areas of mathematics, such as number theory, algebra, and analysis. By understanding these numbers and their properties, we can better understand the structure and behavior of mathematical systems and solve complex mathematical problems.

Lesson:
Title: Understanding Prices with and without VAT
Level: Primary through High school
Section 1: Introduction
In this lesson, we will learn about the concept of Value Added Tax (VAT) and how it affects the prices of goods and services. We will also explore the importance of providing clear and accurate pricing information to customers.
Section 2: What is VAT?
VAT is a tax imposed on goods and services by governments around the world. It is usually calculated as a percentage of the price of the item or service being purchased. The amount of VAT charged can vary depending on the country and the type of product or service being sold.
Section 3: How does VAT affect prices?
When you see a price displayed on a website or in a store, it usually includes the amount of VAT that will be added to the final cost. For example, if you see a price of $10, it means that the customer will have to pay $11 (assuming a VAT rate of 10%).
Section 4: Why is clear pricing information important?
Customers need to know the exact amount they will have to pay for a product or service before making a purchase decision. If the pricing information is not clear, they may feel misled or cheated, which can lead to loss of trust and business.
Section 5: Practical Examples
Let's say you are selling a product for $100. If the VAT rate in your country is 10%, you will have to charge your customer $110 ($100 + 10% of $100). You should make sure that the pricing information on your website or in your store clearly displays the price with and without VAT so that customers can make informed purchasing decisions.
Conclusion:
In conclusion, providing clear and accurate pricing information is essential for building trust and maintaining customer loyalty. By understanding the concept of VAT and its impact on prices, you can ensure that your customers are not surprised by hidden fees or charges. Remember to always display prices with and without VAT to help customers make informed purchasing decisions.
Glossary:
VAT - Value Added Tax
Pricing Information - The amount of money a customer needs to pay for a product or service.
Clear Pricing Information - Pricing information that is easy to understand and does not contain any hidden fees or charges.
Section 6: Self-Debate Discussion
How can you ensure that your pricing information is clear and accurate for customers from different countries with different VAT rates?

Q:

Run a script several times in terminal

I have a file script.sh that contains a specific command that I want to run.
Every time I do ./script.sh I execute this script. This script contains a unique identifier, for example:
... load id_1 /path ...

What I want to do is to run this script n times using different ids.
For example the first time it run it will use id_1, the second one id_2 and so on.
How can I do that?

A:

If your script.sh file contains entry like you have posted:

... load id_1 /path ...

Then one option is to edit it and replace 1 with $1 as listed below:

... load id_$1 /path ...

Run this bash one liner from your shell:
$ for i in $(seq 1 10); do ./script.sh $i ; done

some explanation
seq will print a sequence of numbers e.g. 1 to 10
For example, the below command will print digits from 1 to 100 on your shell

$ seq 1 100

Next is ./script.sh $i
It will pass value of variable $i, created while cycling seq, to script.sh
The instruction id_$1 inside your script.sh will replace $1 with value passed to it from one liner

Lesson: Introduction to Sequences and Series

**Objective:** In this lesson, we will learn about sequences and series, which are important concepts in mathematics. We will explore their definitions, properties, and applications in various scenarios.

**Section 1: Definition and Properties of Sequences and Series**

**Topic 1: Sequences**
- A sequence is an ordered list of numbers, usually written in a specific order.
- The first term of a sequence is called the first element or the initial term.
- The nth term of a sequence is the term that appears in the nth position.
- The sum of the first n terms of a sequence is called the nth term of the series.

**Topic 2: Series**
- A series is the sum of an infinite number of terms, usually arranged in a specific order.
- The common difference between two consecutive terms of a series is called the common ratio.
- The sum of an infinite series can be found using the formula:

    S = (a1 + an + (an2 - an1) + ...)/2

where S is the sum of the series, and a1, an, an2, ... are the first, second, third, ... terms of the series.

**Section 2: Applications of Sequences and Series**

**Topic 1: Finance**
- In finance, sequences and series are used to calculate interest and principal payments on loans, mortgages, and other financial products.
- For example, if you borrow $10,000 at a 5% annual interest rate, you will pay back $10,500 after the first year ($10,000 x (1 + 0.05)).

**Topic 2: Physics**
- In physics, sequences and series are used to calculate energy, momentum, and other physical quantities.
- For example, the total energy of a system can be calculated by summing the kinetic and potential energies of all particles in the system.

**Section 3: Self-Debating Discussion**

**Question:** Why is it important to understand sequences and series in mathematics?

**Answer:** Understanding sequences and series is important because they are used in many areas of mathematics, science, and engineering. They help us to model real-world phenomena, solve problems, and make predictions. Additionally, they provide a way to organize and analyze data, which can lead to new insights and discoveries.

text: Everything to do with medical personnel and hospitals seems to have gone downhill since Gaétan Barrette has been in charge.. Letter: Barrette has been a disappointment. Quebec Health Minister Gaetan Barrette at the legislature in Quebec City.. I thought when Gaétan Barrette was given the job of health minister that was a lucky break for Québécois. He was a doctor, and who better to know how hard nurses and other medical personnel work.. But it soon came to pass that it was not lucky for us, just for Barrette. He acts as if the money is his, and maybe it is, because he is not spending it where it needs to go. Will he get a pitiful raise over five years? I doubt that very much. I am so disappointed by his actions. Everything to do with medical personnel and hospitals seems to have gone downhill since he has been in charge.. Beverley Nowell, St-Lam.

Lesson: Critical Thinking and Analyzing Arguments

**Introduction:** In this lesson, we will learn how to analyze arguments and use critical thinking skills to evaluate their validity. We will use the letter from Beverley Nowell as an example to practice these skills.

**Section 1: Analyzing Arguments**

An argument is a set of statements intended to persuade someone to believe or do something. When analyzing an argument, we need to consider several factors to determine its validity. These factors include the premises, the conclusion, the evidence, and the reasoning.

**Premises:** The premises are the reasons or pieces of evidence that support the conclusion. In the letter, Beverley Nowell expresses her disappointment with the healthcare system under Gaétan Barrette's leadership. She mentions that the healthcare system has gone downhill since he became the health minister.

**Conclusion:** The conclusion is the result that the arguer wants the audience to believe or accept. In this case, Beverley Nowell concludes that Gaétan Barrette has been a disappointment as the health minister.

**Evidence:** The evidence is the supporting information that the arguer uses to convince the audience of the conclusion. In the letter, Beverley Nowell provides evidence such as the poor working conditions for medical personnel and the lack of funding for hospitals.

**Reasoning:** The reasoning is the process by which the arguer connects the premises to the conclusion. In this case, Beverley Nowell assumes that if Gaétan Barrette were truly invested in improving healthcare, he would invest more resources into it.

**Section 2: Evaluating Arguments**

Once we have analyzed the argument, we can evaluate its validity by considering several factors. These factors include the strength of the premises, the relevance of the evidence, the soundness of the reasoning, and the credibility of the source.

**Strength of Premises:** In this case, the premises seem to be weak because they are based on personal opinions rather than on concrete data or facts.

**Relevance of Evidence:** The evidence provided in the letter seems to be relevant because it mentions specific issues such as the poor working conditions for medical personnel and the lack of funding for hospitals.

**Soundness of Reasoning:** The reasoning seems to be unsound because it relies on assumptions rather than on concrete evidence.

**Credibility of Source:** The source of the argument, Beverley Nowell, may not be entirely credible because she is expressing personal opinions rather than providing concrete data or facts.

**Section 3: Applying Critical Thinking Skills**

Now that we have analyzed and evaluated the argument, we can apply critical thinking skills to determine its validity. We can ask ourselves several questions to guide our analysis:

- Are the premises based on concrete data or facts?
- Is the evidence relevant to the conclusion?
- Is the reasoning sound and based on concrete evidence?
- Is the source credible?

By asking these questions, we can evaluate the argument's validity and make an informed decision about whether to accept or reject it.

**Conclusion:** In this lesson, we learned how to analyze and evaluate arguments using critical thinking skills. We practiced these skills by analyzing a letter from Beverley Nowell about the healthcare system under Gaétan Barrette's leadership. By applying critical thinking skills, we can determine the validity of arguments and make informed decisions about what to believe or do.

**Glossary:**
- Argument: A set of statements intended to persuade someone to believe or do something.
- Premises: The reasons or pieces of evidence that support the conclusion.
- Conclusion: The result that the arguer wants the audience to believe or accept.
- Evidence: The supporting information that the arguer uses to convince the audience of the conclusion.
