Lesson: Understanding Sales and Discounts

Introduction:
In this lesson, we will learn about sales and discounts. We will start by understanding what a sale is and how it affects the price of a product. Then, we will learn about different types of discounts and how to calculate them. Finally, we will apply our knowledge to a real-world scenario.

Section 1: What is a Sale?
A sale is an event where a store offers products at a lower price than their regular price. This is usually done to encourage people to buy more products or to get rid of old inventory. When a product is on sale, it means that the price has been reduced, and the customer can buy it for less money than usual.

Section 2: Types of Discounts
There are several types of discounts that stores offer during sales. These include:

1. Percentage discount: This is the most common type of discount. It is calculated as a percentage of the original price. For example, if a product costs $100 and has a 20% discount, the new price would be $80 ($100 x 0.8 = $80).

2. Fixed amount discount: This discount is a fixed amount that is deducted from the original price. For example, if a product costs $100 and has a $20 discount, the new price would be $80 ($100 - $20 = $80).

3. Buy one, get one free (BOGO): This discount allows customers to buy one product and get another one for free. The original price of the second product is deducted from the total cost.

Section 3: Calculating Discounts
To calculate a discount, we need to know the original price of the product and the discount percentage or amount. Once we have this information, we can use the following formulas:

Percentage discount: (Discount percentage / 100) x Original price = New price

Fixed amount discount: Discount amount x Original price = New price

For example, if a product costs $100 and has a 10% discount, the new price would be $90 ($100 x 0.1 = $10).

Section 4: Real-World Scenario
Let's say you want to buy a tent that costs $500. You find a sale advertisement that says the tent is on sale for 30% off. How much money will you save if you buy the tent during the sale?

First, we need to calculate the discount amount:

Discount amount = (Discount percentage / 100) x Original price
Discount amount = (30 / 100) x 500
Discount amount = 150

Now, we can calculate the new price:

New price = Original price - Discount amount
New price = 500 - 150
New price = $350

So, if you buy the tent during the sale, you will save $150.

Conclusion:
In this lesson, we learned about sales and discounts. We learned that a sale is when a store offers products at a lower price than their regular price. We also learned about different types of discounts and how to calculate them. Finally, we applied our knowledge to a real-world scenario to see how much money we could save on a tent purchase.

Q:

Searching and replacing Verilog code using Perl

I have some expressions in a file:
   e = a & b;
   f = e | c;
   d = ~f;

I need to resolve these expressions into a compound expression like this:
   d = ~ ((a & b) | c)

How can I do this in Perl. Are there any CPAN modules that I can use for this? Or, can this be done without using modules?
I am working on a verilog parser project.

A:

The Verilog-Perl distribution on CPAN can be used to parse your Verilog code to create a list of signals.  If you have full control over the layout of your Verilog code, you don't need to use this module.  However, keep in  mind that parsing Verilog is not trivial.

Lesson: How to Search and Replace Verilog Code Using Perl

## Introduction

In this lesson, we will learn how to search and replace Verilog code using Perl. We will cover the following topics:

1. Understanding Verilog code
2. Using regular expressions to search and replace code
3. CPAN modules for Verilog parsing
4. Practical examples

## Section 1: Understanding Verilog code

Verilog is a hardware description language (HDL) used to describe electronic circuits. It is widely used in the design of digital circuits, such as those found in microprocessors and computer memory systems. Verilog code is written in a textual format and consists of statements that describe the behavior of electronic circuits.

## Section 2: Using regular expressions to search and replace code

Regular expressions are a powerful tool for searching and replacing text in Perl. They allow us to search for patterns in text and replace them with other text. In this section, we will learn how to use regular expressions to search and replace Verilog code.

First, let's consider an example of Verilog code that needs to be modified:

```
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
```

We want to change the condition inside the if statement so that it evaluates to true only when another condition is met. One way to do this is to replace `condition` with `condition && another_condition`.

To do this, we can use the `s///` operator in Perl. This operator performs a substitution on the input string. Here's an example:

```perl
$verilog_code = <<'END_VERILOG_CODE';
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
END_VERILOG_CODE
$verilog_code =~ s/(condition)/(condition && another_condition)/g;
print $verilog_code;
```

In this example, we first define the Verilog code as a string variable called `$verilog_code`. We then use the `=~` operator to perform a substitution on the string. The `s` subroutine takes two arguments: the first argument is a regular expression that matches the old text to be replaced, and the second argument is the new text to replace it with. The `/g` flag at the end ensures that all occurrences of the old text are replaced. Finally, we print out the modified Verilog code.

## Section 3: CPAN modules for Verilog parsing

If you are working on a Verilog parser project, you may want to consider using a CPAN module for parsing Verilog code. One such module is called "Verilog-Perl". This module provides a set of functions for parsing Verilog code and creating a syntax tree. You can use this syntax tree to search and replace code as needed.

Here's an example of how to use the "Verilog-Perl" module:

```perl
use strict;
use warnings;

use Verilog::Parser;

my $verilog_code = <<'END_VERILOG_CODE';
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
END_VERILOG_CODE

my $parser = Verilog::Parser->new();
$parser->parse_string($verilog_code);

foreach my $node ($parser->root()->children()) {
  print "$node->[0] - $node->[1]\n";
}
```

In this example, we first define the Verilog code as a string variable called `$verilog_code`. We then create a new instance of the "Verilog::Parser" class and pass in the Verilog code to be parsed. We can then use the `->children()` method to get a list of all the nodes in the syntax tree. Finally, we loop through each node and print out its position and type.

## Section 4: Practical examples

Now that we have covered the basics of searching and replacing Verilog code using regular expressions and CPAN modules, let's consider some practical examples:

Example 1: Changing the name of a signal

Suppose we have the following Verilog code:

```
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
```

We want to change the name of the output signal `a` to `b`. We can do this by searching for the word "a" and replacing it with "b". Here's an example:

```perl
$verilog_code = <<'END_VERILOG_CODE';
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
END_VERILOG_CODE

$verilog_code =~ s/(a)/b/g;
print $verilog_code;
```

Example 2: Adding a new module

Suppose we have the following Verilog code:

```
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
```

We want to add a new module called "my_second_module" that has an input called "clk", an input called "rst", and an output called "b". Here's an example:

```perl
$verilog_code = <<'END_VERILOG_CODE';
module my_module (input wire clk, input wire rst, output reg a);
  always @(posedge clk) begin
    if (!rst) begin
      a <= 1;
    end else if (condition) begin
      a <= 0;
    end
  end
endmodule
module my_second_module (input wire clk, input wire rst, output reg b);
  always @(posedge clk) begin
    if (!rst) begin
      b <= 1;
    end
  end
endmodule
END_VERILOG_CODE

print $verilog_code;
```

Conclusion

In this lesson, we learned how to search and replace Verilog code using regular expressions and CPAN modules. We covered the basics of Verilog code, how to use regular expressions to search and replace code, and practical examples of modifying Verilog code. We also discussed the "Verilog-Perl" module for parsing Verilog code. By mastering these techniques, we can apply them to new problems and modify Verilog code as needed.

Lesson Title: Introduction to Electrical Meters

## Section 1: Theoretical Concepts

### Subsection 1.1: What are Electrical Meters?
Electrical meters are devices used to measure the amount of electricity consumed by a household or business. They are typically installed by the electric utility company and are used to calculate the amount of electricity used and the cost of that usage. There are several types of electrical meters, including analog meters, digital meters, and smart meters.

### Subsection 1.2: How do Electrical Meters Work?
Electrical meters work by measuring the amount of electric current flowing through a circuit. This is typically done using a device called an electromechanical meter, which consists of a series of magnetic coils that are activated by the flow of electric current. As the current flows through the coils, it generates a magnetic field that causes a mechanical device, such as a rotating disk or a dial, to rotate. The rotation of the mechanical device is then used to display the amount of electricity used on a digital or analog display.

### Subsection 1.3: Why are Electrical Meters Important?
Electrical meters are important because they allow electric utility companies to accurately measure the amount of electricity used by their customers. This information is used to calculate the cost of electricity usage, which is then billed to the customer. Electrical meters also provide valuable data to utility companies, which can be used to identify areas where energy is being wasted or where improvements can be made to the electrical grid.

## Section 2: Practical Examples

### Subsection 2.1: Analog vs. Digital Meters
Analog meters use a mechanical device to display the amount of electricity used, while digital meters use electronic displays to show the same information. Digital meters are typically more accurate than analog meters and can provide more detailed information about electricity usage. However, analog meters are often easier to read and require less maintenance than digital meters.

### Subsection 2.2: Smart Meters
Smart meters are a type of electrical meter that can communicate with other devices, such as a home computer or a smartphone, to provide real-time information about electricity usage. Smart meters can also be programmed to turn off appliances or reduce electricity usage during peak demand periods, which can help to reduce energy costs and improve the reliability of the electrical grid.

## Section 3: Self-Debating Discussions

### Subsection 3.1: Pros and Cons of Smart Meters
One of the benefits of smart meters is that they can provide real-time information about electricity usage, which can help customers to identify areas where they can save energy and reduce their energy bills. However, some customers may be concerned about the privacy implications of having a smart meter installed, as the device can potentially be used to monitor electricity usage in real-time. Additionally, there may be concerns about the reliability of smart meters and the potential for cyber attacks on the devices.

## Glossary
- Electrical Meter: A device used to measure the amount of electricity consumed by a household or business.
- Electromechanical Meter: A type of electrical meter that uses a series of magnetic coils to measure the amount of electric current flowing through a circuit.
- Analog Meter: A type of electrical meter that uses a mechanical device, such as a rotating disk or a dial, to display the amount of electricity used.
- Digital Meter: A type of electrical meter that uses electronic displays to show the amount of electricity used.
- Smart Meter: A type of electrical meter that can communicate with other devices to provide real-time information about electricity usage.

## Conclusion
In conclusion, electrical meters are important devices that are used to measure the amount of electricity consumed by households and businesses. Understanding the different types of electrical meters and their functions can help customers to make informed decisions about their energy usage and to identify areas where they can save energy and reduce their energy bills.

Lesson: Distributing Python Packages as Separate Distributions

Introduction:
Python packages are collections of modules that work together to perform a specific task. Distributing these packages as separate distributions can make it easier for users to install and use the package. In this lesson, we will learn how to create separate distributions for existing packages without splitting up anything else.

Section 1: Understanding Separate Distributions

Topic 1: Why Distribute Packages Separately?
- Separate distributions allow users to install only the necessary components of a package.
- This reduces the size of the package and makes it easier to manage dependencies.

Topic 2: Creating Separate Distributions
- To create separate distributions, you need to create a new project with its own setup.py and project name.
- You can use the same source code for the new project as long as it is not part of the original package.

Section 2: Creating a Separate Distribution for Paste Deploy

Topic 1: Identifying the Subpackage
- Paste deploy is a subpackage of the Paste package.
- It contains modules that are used for deployment purposes.

Topic 2: Creating a New Project
- Create a new directory for the new project.
- Copy the source code for Paste deploy into the new directory.
- Rename the project to "Paste-Deploy" or something similar.

Topic 3: Creating the Setup File
- Create a new setup.py file for the new project.
- Use the "setuptools" library to create the setup file.
- Add the following code to the setup file:

```
from setuptools import setup

setup(
    name="Paste-Deploy",
    version="0.1",
    author="Ian Bicking",
    author_email="ianb@colorstudy.com",
    packages=["paste"],
    package_dir={"paste": "paste"},
    scripts=[],
    license="BSD",
    zip_safe=False,
    url="http://www.paste-project.org",
    download_url="http://www.paste-project.org/downloads/",
)
```

Topic 4: Building and Installing the Distribution
- Use the "setup" command to build and install the distribution.
- Make sure the installation goes smoothly by running tests and checking for errors.

Section 3: Conclusion

In this lesson, we learned how to create separate distributions for existing packages without splitting up anything else. We learned why it is important to distribute packages separately and how to create a new project, create a setup file, and build and install the distribution. By following these steps, we can create a separate distribution for Paste deploy that users can easily install and use.

Lesson: Introduction to Cryptography

## Section 1: Theoretical Concepts
Cryptography is the practice of securing information by converting it into a code that can only be read by those who possess the necessary tools to decipher it. This is done through the use of algorithms, which are sets of rules that dictate how data is transformed. The two main types of cryptography are symmetric and asymmetric. Symmetric cryptography uses the same key to encrypt and decrypt data, while asymmetric cryptography uses two different keys - one for encryption and one for decryption.

## Section 2: Practical Examples
One practical example of cryptography is sending passwords over the internet. When you log into an account on a website, the password you enter is sent over the internet in plain text. This means that anyone who intercepts the transmission could potentially see your password. However, if the website uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security), your password is encrypted before it is sent. This means that even if someone were to intercept the transmission, they would not be able to read your password.

Another practical example is sending credit card information over the internet. When you make a purchase online, you need to provide your credit card number, expiration date, and security code. If the website does not use cryptography to secure this information, someone could potentially intercept the transmission and steal your credit card information. However, if the website uses cryptography to encrypt the transmission, your credit card information is safe.

## Section 3: Real-World Scenarios
One real-world scenario where cryptography is used is in online banking. When you log into your online banking account, you are typically asked to provide your username and password. If the website uses cryptography to secure the login process, your information is encrypted before it is transmitted. This means that even if someone were to intercept the transmission, they would not be able to read your password or account information.

Another real-world scenario is in government communications. Governments often communicate sensitive information, such as diplomatic negotiations or military plans, over secure channels. This is done using cryptography to ensure that the information remains confidential and cannot be intercepted or read by unauthorized parties.

## Glossary
- Cryptography: The practice of securing information by converting it into a code that can only be read by those who possess the necessary tools to decipher it.
- Algorithm: A set of rules that dictate how data is transformed.
- Symmetric cryptography: The use of the same key to encrypt and decrypt data.
- Asymmetric cryptography: The use of two different keys - one for encryption and one for decryption.
- SSL (Secure Sockets Layer): A protocol that provides secure communication over the internet.
- TLS (Transport Layer Security): A protocol that provides secure communication over the internet.

## Conclusion
Cryptography is an important tool for securing information over the internet. By converting data into a code that can only be read by those who possess the necessary tools to decipher it, we can protect sensitive information from being intercepted and read by unauthorized parties. As we continue to rely more and more on online communication, it is important that we understand the principles of cryptography and how it can be used to keep our information safe.

**Title:** Restful Web Services with Spring

**Level:** Intermediate

**Duration:** 1 week

**Objective:** In this lesson, we will learn about creating restful web services using Spring framework. We will cover the following topics:

1. Introduction to Restful Web Services
2. Creating a RESTful Web Service with Spring
3. Securing a RESTful Web Service with Spring Security
4. Testing a RESTful Web Service with Spring
5. Exception Handling in a RESTful Web Service with Spring
6. Versioning a RESTful Web Service with Spring

**Introduction to Restful Web Services:**

Restful web services are a type of web service that uses HTTP requests to perform operations on resources. These operations are usually performed using HTTP verbs like GET, POST, PUT, DELETE, etc. A restful web service is typically stateless, meaning that each request from the client must contain all the necessary information to understand and fulfill the request.

**Creating a RESTful Web Service with Spring:**

To create a RESTful web service with Spring, we need to use the Spring Boot framework. Spring Boot provides an easy way to create a RESTful web service by providing an embedded web server and configuration. We will create a simple RESTful web service that exposes a resource called "users".

**Securing a RESTful Web Service with Spring Security:**

Spring Security is a powerful framework for securing web applications. It provides a wide range of features for securing a RESTful web service, including authentication, authorization, and encryption. In this section, we will learn how to configure Spring Security to secure our RESTful web service.

**Testing a RESTful Web Service with Spring:**

Testing a RESTful web service can be challenging because it requires knowledge of both the HTTP protocol and the domain model of the application. In this section, we will learn how to test a RESTful web service with Spring using the TestRestTemplate class.

**Exception Handling in a RESTful Web Service with Spring:**

Exception handling is an important part of any web application. In a RESTful web service, exceptions can occur when a client sends an invalid request or when there is an error in the server-side code. In this section, we will learn how to handle exceptions in a RESTful web service with Spring.

**Versioning a RESTful Web Service with Spring:**

Versioning a RESTful web service can be challenging because it requires deciding on a versioning strategy and implementing it consistently. In this section, we will learn about two common versioning strategies: using a version identifier in the URI and using version media types.

**Conclusion:**

In this lesson, we have learned about creating restful web services using Spring framework. We covered the basics of RESTful web services and then dived into more advanced topics like securing, testing, and exception handling in a RESTful web service. By the end of this lesson, you will be able to create, secure, test, and version a RESTful web service using Spring.

The present invention relates to a pneumatic radial tire for heavy loads, and more particularly to an improvement upon tread reinforcement to prevent structural failure and to diminish uneven wear of the tread.
In general, for pneumatic radial tires used for heavy loads for trucks and buses, there has been widely used the so-called steel radial ply tire. Such a tire comprises a carcass of radially arranged steel cords with the ends turned up around bead cores and a belt composed of 3 or 5 belt plies arranged on the crown of the carcass. Structural failure of the carcass and that of the bead was greatly decreased by improvement upon the carcass and bead structures, and the tires became used under more severe conditions such as higher speed and heavier loads.
Accordingly, with tires for heavy loads used under such conditions, inasmuch as its ground contacting pressure is much higher than that of passenger care tires, the so-called shoulder wear--uneven wear in which the edge part of the tread is greatly worn by slip against the road surface--is liable to be caused by the uneven rigidity of the tread and also by the difference between the diameters of the central part and the edge part of the tread.
Furthermore, due to the heat and strain generated by the tire rotation, the so-called tread separation--structural damage caused by an adhesive failure between the belt cords and rubber expanding from the belt ends of the third belt ply--is liable to result.

Question: What is a pneumatic radial tire?
Answer: A pneumatic radial tire is a type of tire that is designed to carry heavy loads. It is made up of a series of steel cords that are arranged in a radial pattern and are reinforced with a belt of rubber. This design allows the tire to provide a smooth ride while also being able to handle the weight of heavy vehicles.

Question: How does a pneumatic radial tire work?
Answer: A pneumatic radial tire works by inflating the air inside the tire to a specific pressure. This creates a seal between the tire and the wheel rim, which helps to distribute the weight of the vehicle evenly across the tire. The steel cords in the tire provide strength and durability, while the rubber belt helps to prevent structural failure and diminish uneven wear of the tread.

Section 2: Design and Function of Pneumatic Radial Tires

Question: What are the main components of a pneumatic radial tire?
Answer: The main components of a pneumatic radial tire are the carcass, the belt, and the tread. The carcass is made up of a series of steel cords that are arranged in a radial pattern and are reinforced with a belt of rubber. The belt is composed of 3 or 5 belt plies that are arranged on the crown of the carcass. Finally, the tread is the outermost layer of the tire, which provides traction and protection against wear and tear.

Question: What is shoulder wear, and how can it be prevented?
Answer: Shoulder wear is a type of wear that occurs on the edges of the tread, where the tire is subjected to higher pressures and more friction against the road surface. This can cause the tire to wear out more quickly, especially in heavy-duty applications. To prevent shoulder wear, manufacturers often use a combination of materials and designs, such as incorporating more rubber into the tread or using a more rigid compound.

Section 3: Challenges and Solutions for Pneumatic Radial Tires

Question: What are some common challenges associated with pneumatic radial tires?
Answer: Some common challenges associated with pneumatic radial tires include uneven wear, structural failure, and increased risk of blowouts. These issues can be caused by a variety of factors, including poor tire maintenance, excessive speed, and improper loading.

Question: How can these challenges be addressed?
Answer: There are several steps that can be taken to address these challenges. For example, proper tire maintenance, including regular inspections and rotations, can help to prevent uneven wear and structural failure. Additionally, drivers can be trained to avoid excessive speed and improper loading, which can contribute to these issues. Finally, manufacturers can continue to improve their designs and materials to reduce the risk of blowouts and other tire-related accidents.

Conclusion:
In conclusion, pneumatic radial tires are a crucial component of many heavy-duty vehicles, providing improved handling, reduced wear and tear, and increased fuel efficiency. By understanding the design and function of these tires, as well as the challenges associated with their use, we can ensure that they continue to provide safe and reliable transportation for years to come.

University of Illinois emergency ventilator project finds a manufacturer

Less than two months after they started to design a low-cost ventilator for emergency use, engineers and doctors at the University of Illinois at Urbana-Champaign have cleared the biggest hurdle they faced — finding a company to build the machines.

Of all the efforts to build portable, lower-cost ventilators to help treat COVID-19 patients who are unable to breathe on their own, the U. of I. model is among the simplest, and the cheapest. The ventilator runs off of oxygen pressure — without electricity — and the manufacturer says it will cost less than $200.

The university reached an agreement this month with Belkin, a maker of cellphone chargers and other accessories, to manufacture 10,000 ventilators a month at a factory in Rhode Island, according to the company.

U. of I. engineers spent about three weeks designing and testing prototypes, including using them on pigs. The result was an emergency ventilator small and cheap enough to be stockpiled by the thousands, said William King, a professor of mechanical engineering.

“It’s a relatively simple device,” King said. “The one we designed is less than half a pound. It’s smaller than a loaf of bread, and it has around 20 mechanical components.”

The project was launched in mid-March when doctors at Carle Health, the university-affiliated hospital system in Champaign-Urbana, reached out to the engineering faculty and expressed concern about the possibility of ventilator shortages if central Illinois was overrun with COVID-19 cases.

“Carle was planning for a worst-case scenario, where there would be hundreds, or even thousands, of patients in our community that needed a ventilator and one would not be available to them,” King said. “Of course, this situation has not transpired, very fortunately for us. But around this time, there were many communities around the country and around the world that were grappling with the exponential increase in COVID cases and the potential that some hospitals would be overwhelmed.”

The university decided to make the design available as a free license to anybody interested. More than 60 companies, across 15 countries, have become licensees. But Belkin will be the first to actually make the machines.

California-based Belkin is owned by Foxconn Interconnect Technologies, a subsidiary of the massive Taiwanese electronics manufacturer Foxconn Technology Group. Foxconn Internet Technologies and U. of I. have an existing relationship, as the company announced a $50 million gift last year to fund a partnership with the university to build a new technology development center for the Grainger College of Engineering. The company also has an office in the university’s research park in Champaign.

“We’ve been having extensive conversations with them about all kinds of things, and this was something we were working on that they were interested in, as well,” King said. Foxconn sent the design to Belkin to be built.

Belkin has applied for emergency approval from the U.S. Food and Drug Administration, which the company hopes will be awarded by the end of May, a spokeswoman said.

Given the unpredictable demands of the pandemic, company officials say they won’t know what the demand for the devices is until they clear FDA approval and get into the market.

“There is concern the virus will come back in the summer and fall and that it would be prudent to prepare for potential surges,” said Belkin spokeswoman Jen Warren. “In an earlier, more critical stage of the pandemic, it was clear there was a critical need for ventilators and not just for the short term.”

Donald Trump wants you to know that he sees you, and more importantly, he sees… that you see… what’s happening.

If you’ve watched our video on Donald Trump’s public speaking tricks, then you’re aware of the standout methods our president employs to not only hold an audience’s attention but also connect deeply with them.

Now we can add “You see what’s happening” to that bag of tricks.

How does it work exactly? Well, it’s very simple: Just say “You see what’s happening with …” and then slot in any topic of your choosing. It can be specific (say, the company Chrysler) or vague to the point of meaninglessness (what they’re doing with certain countries) or ominous-sounding to stoke fear (what's happening in our country). And — boom! — you accomplish multiple things at once. For one, you convey the impression that you have some knowledge of the topic, without having to provide specifics (Uh-oh, I’m in the middle of an important policy speech and I just realized I don’t have the precise details or statistics on this subject at my fingertips). Not a problem! You already see what’s happening, so I don’t need to give you those details.

Just as importantly, “You see what’s happening” flatters the audience by telling them you realize they’re smart and savvy enough to already see this thing themselves. And what is it that they see, exactly? Well, that’s the genius of “you see what’s happening”: You give the audience the freedom to fill in that blank with whatever opinions/hopes/fears/fantastical conspiracy theories they might have. By saying “You see what’s happening,” you’re not only complimenting your audience’s intelligence, you’re also implicitly saying that you share whatever opinion they fill that space with.

Repetition is a rhetorical device that involves repeating a word, phrase, or idea for emphasis or effect. It is a common technique used by speakers to reinforce their message and create a stronger impact on their audience.

Section 2: Types of Repetition
There are several types of repetition that you can use in your speeches, including:

1. Alliteration: This occurs when you repeat the same consonant sound at the beginning of multiple words in a row. For example, "I have a dream" is an example of alliteration.

2. Assonance: This occurs when you repeat the same vowel sound in multiple words in a row. For example, "The sound of silence" is an example of assonance.

3. Rhyme: This occurs when you repeat the same ending sound in multiple words in a row. For example, "Twinkle, twinkle, little star" is an example of rhyme.

4. Repetition of key phrases: This occurs when you repeat a key phrase or sentence throughout your speech to emphasize your message. For example, if you were giving a speech about the importance of education, you might repeat the phrase "education is the key" throughout your speech.

Section 3: How to Use Repetition Effectively
To use repetition effectively in your speeches, follow these tips:

1. Use repetition sparingly: Overuse of repetition can become monotonous and annoying. Use it sparingly to emphasize key points and create a stronger impact on your audience.

2. Use different types of repetition: Mix up the types of repetition you use to keep your speech interesting and engaging. For example, you could use alliteration in one part of your speech and repetition of key phrases in another.

3. Vary the length of your repetitions: Vary the length of your repetitions to keep your audience engaged. For example, you could repeat a key phrase for emphasis, then move on to a different topic before coming back to repeat the same phrase again later in your speech.

Section 4: Practice Exercise
Practice using repetition in the following speech:

My fellow Americans, we have a problem. We have a problem with our economy. We have a problem with our education system. We have a problem with our healthcare system. But we have a solution. We have a solution that will fix all of these problems. We need to come together as a nation and work towards a brighter future for all of us. We need to take action now. We need to take action before it's too late.
