Lesson: Introduction to Computer Systems

## Section 1: Overview of Computer Systems

A computer system is a combination of hardware and software that works together to perform specific tasks. Hardware refers to the physical components of a computer, such as the motherboard, processor, memory, storage devices, and input/output devices. Software, on the other hand, refers to the programs and applications that run on the computer, such as operating systems, drivers, utilities, and user applications.

## Section 2: Components of a Computer System

A computer system is made up of several components, including:

1. Motherboard: This is the main circuit board of a computer, which connects all of the other components together. It contains the CPU, memory slots, expansion slots, and other important components.

2. Processor (CPU): This is the brain of the computer, responsible for executing instructions and performing calculations. It is typically a small chip located on the motherboard.

3. Memory (RAM): This is the temporary storage area where the computer stores data and instructions that it is currently working on. The more RAM a computer has, the more programs it can run simultaneously.

4. Storage Devices: These are used to store data and programs permanently on the computer. Examples include hard drives, solid-state drives, and optical drives.

5. Input/Output Devices: These are used to interact with the computer, either by entering data or receiving output. Examples include keyboards, mice, monitors, printers, and speakers.

## Section 3: How Computer Systems Work Together

Computer systems work together by following a series of steps to perform tasks. These steps include:

1. Input: The user enters data into the computer using an input device, such as a keyboard or mouse.

2. Processing: The CPU processes the data by executing instructions and performing calculations.

3. Output: The computer displays the results of its processing on an output device, such as a monitor or printer.

4. Storage: The computer stores the results of its processing in a storage device, such as a hard drive or solid-state drive.

## Section 4: Practical Examples

Here are some practical examples of how computer systems work together:

1. Browsing the Web: When you visit a website, your computer sends a request over the internet to the server hosting the website. The server sends back the HTML code for the page, which your computer's CPU processes and displays on your monitor.

2. Playing a Video Game: When you play a video game, your computer sends instructions to the CPU to render the graphics and handle user input. The CPU then processes the instructions and sends the necessary data to the graphics card and input devices.

3. Creating a Document: When you create a document, your computer's CPU processes your keystrokes and displays them on the monitor. As you type, the CPU stores the data in memory and saves it to a storage device when you exit the program.

## Conclusion

In conclusion, computer systems are made up of hardware and software components that work together to perform specific tasks. By understanding the components of a computer system and how they work together, we can better understand how to use computers effectively and efficiently.

Lesson: Introduction to Photography

## Section 1: Theoretical Concepts

Photography is the art of capturing light and turning it into an image. It involves the use of cameras, lenses, and other equipment to create photographs. In this lesson, we will explore the basics of photography and learn about the different types of cameras, lenses, and settings used in photography.

## Section 2: Practical Examples

Let's say you want to take a picture of your friend. You can use a camera with a wide-angle lens to capture more of the background and create a sense of depth in the photo. You can also adjust the aperture setting to create a blurry background, which is known as bokeh.

## Section 3: Real-World Scenarios

Now let's say you want to take a picture of a landscape. You can use a camera with a telephoto lens to zoom in on a distant object, such as a mountain or a building. You can also use a tripod to keep the camera steady and avoid blurring the image. Additionally, you can adjust the shutter speed to capture movement or freeze motion.

## Glossary

- Camera: A device that captures light and turns it into an image.
- Lens: A piece of glass or plastic that focuses light onto the camera sensor.
- Aperture: The opening in the lens that controls the amount of light that enters the camera.
- Shutter Speed: The length of time that the camera's shutter is open, which affects the exposure of the image.
- ISO: The sensitivity of the camera sensor to light.

## Conclusion

In this lesson, we learned about the basics of photography, including the different types of cameras, lenses, and settings used in photography. We also explored practical examples and real-world scenarios to help us understand how to apply these concepts in our own photography. By understanding these concepts, we can improve our photography skills and create stunning images.

Lesson: How to Read and Understand Diff Output

Introduction:
In this self-taught lesson, we will learn how to read and understand the output of the "diff" command. The "diff" command is a powerful tool used in software development and version control systems like Git to compare two files or directories line by line and display the differences between them. This skill is essential for developers, system administrators, and anyone who works with code or text files.

Section 1: Theoretical Concepts
The "diff" command compares two files or directories line by line and displays the differences between them. It uses a number of flags and options to control how the comparison is done. Some of the most commonly used flags are "-q", "-w", and "-y".

-q (quiet): This flag suppresses the display of diff output. Instead, it only displays whether the files are the same or not.
-w (word): This flag considers two lines to be the same if they differ only in whitespace.
-y (context): This flag compares the context around each hunk of diff information, instead of just the hunks themselves.

Section 2: Practical Examples
Let's say we have two versions of a file, "file1.txt" and "file2.txt", and we want to see the differences between them using the "diff" command. We can do this by running the following command:

```
diff -qw file1.txt file2.txt
```

This will compare the two files line by line and display any differences. If there are no differences, the command will output "Files file1.txt and file2.txt are the same."

Now let's say we have made some changes to "file1.txt" and want to see what has been added or removed. We can do this by running the following command:

```
diff -u file1.txt file2.txt
```

This will show us the changes that have been made to the file, with the added or removed text highlighted.

Section 3: Real-World Scenarios
In a software development environment, developers often use the "diff" command to compare the current state of their code with the previous version before making changes. This helps them to identify and fix any errors that may have been introduced.

System administrators also use the "diff" command to compare configuration files or system logs to identify any changes that may have been made.

Glossary:
- diff: A command-line utility that compares two files or directories line by line and displays the differences between them.
- flags: Options that can be used with the "diff" command to control how the comparison is done.
- hunks: A group of lines that are either added or removed from a file.

Conclusion:
Understanding how to read and interpret the output of the "diff" command is an essential skill for anyone who works with code or text files. By mastering this skill, you can quickly identify and fix errors, track changes, and collaborate more effectively with other developers or system administrators.

Lesson: Understanding International Organizations and Alliances

Introduction:
International organizations and alliances are groups of countries that work together to achieve common goals. These groups can help promote peace, security, and cooperation among their members. In this lesson, we will learn about two important international organizations: the G7 and NATO.

The G7:
The G7, or Group of Seven, is an informal organization of seven wealthy democracies: Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The G7 was formed in 1975 to discuss economic issues, but it has since expanded its focus to include other topics such as climate change, health, and security.

The G7 meetings are held annually, and the leaders of each country discuss important global issues and make decisions on how to address them. For example, at the 2018 G7 summit, the leaders discussed climate change, trade, and security.

NATO:
NATO, or the North Atlantic Treaty Organization, is a military alliance of 30 countries in North America and Europe. NATO was founded in 1949 to protect its members from the Soviet Union and other potential threats. Today, NATO's mission is to promote peace and security by working together to defend its members and to promote cooperation among its members.

NATO member countries agree to come to the aid of any other member country that is attacked. This agreement is called the North Atlantic Treaty, and it is the foundation of NATO's existence.

Conclusion:
International organizations and alliances play an important role in promoting peace, security, and cooperation among countries. The G7 and NATO are two examples of such organizations. By working together, these groups can achieve common goals and protect their members from threats.

Lesson: Understanding Clothing Sizes and Measurements

Introduction:
Clothing sizes can be confusing, especially when shopping online or buying clothes from different brands. In this lesson, we will learn about clothing sizes, measurements, and how to determine the right fit for you.

Section 1: Understanding Clothing Sizes

Topic 1: Standard Clothing Sizes
Most clothing manufacturers use standard sizes to label their products. These sizes are based on body measurements and are designed to fit people of average height and weight. However, there are variations in size charts among different brands and even within the same brand.

Topic 2: Understanding Size Charts
To understand clothing sizes, you need to know how to read size charts. Size charts provide information about the size range of a particular brand or product. They usually include measurements such as bust, waist, hips, and height. You can use these measurements to determine which size would fit you best.

Topic 3: Converting Clothing Sizes
Different countries use different clothing size systems. For example, the United States uses a number system (e.g., size 6), while Europe uses a size chart that corresponds to specific measurements (e.g., 38). To convert clothing sizes, you can use online conversion tools or ask a sales assistant for help.

Section 2: Measuring Your Body

Topic 1: Taking Accurate Measurements
To determine the right clothing size for you, you need to take accurate body measurements. Start by measuring your bust, waist, hips, and height. Use a soft tape measure and make sure you take the measurements at the right spots. You can find guides online that show you where to measure and how to get accurate results.

Topic 2: Using Measurements to Determine Size
Once you have taken your measurements, you can use them to determine your clothing size. Compare your measurements to the size chart of the clothing item you want to buy. Choose the size that corresponds to your measurements or that fits you best.

Section 3: Finding the Right Fit

Topic 1: Considering Fit and Style
In addition to size, you also need to consider fit and style when buying clothing. A well-fitted garment will enhance your appearance and make you feel confident. Look for clothing items that fit well in the bust, waist, and hips. Also, consider the style of the clothing item. Make sure it matches your personal style and fashion preferences.

Topic 2: Buying Clothing Online
Buying clothing online can be tricky, especially when it comes to finding the right fit. However, there are some tips you can follow to increase your chances of getting the right size. First, check the size chart of the brand or product. Second, read customer reviews to see if other people had issues with sizing. Finally, consider buying from a retailer with a good return policy in case the clothing item doesn't fit.

Conclusion:
Understanding clothing sizes and measurements is essential for finding the right fit and enhancing your appearance. By taking accurate body measurements and comparing them to size charts, you can determine the right size for you. Additionally, considering fit and style will help you make informed purchasing decisions. Remember to always try on clothes before making a final purchase to ensure they fit well and flatter your body.

Glossary:
- Bust: The measurement around the chest, usually taken just below the armpits and above the breasts.
- Waist: The measurement around the narrowest part of the torso, usually taken at the navel level.
- Hips: The measurement around the widest part of the hips, usually taken low down on the hips.
- Height: The measurement from head to toe, usually taken while standing up straight.

Lesson: Introduction to Tools and Their Uses

**Section 1: Introduction**

In this lesson, we will learn about different types of tools and their uses. We will focus on the Feedback Sports Spoke Wrench as an example.

**Section 2: What is a Spoke Wrench?**

A spoke wrench is a tool used to tighten or loosen the spokes on a bike wheel. It is also known as a "nipple wrench" or "wheel truing tool."

**Section 3: How does a Spoke Wrench work?**

The Feedback Sports Spoke Wrench is a 4-in-1 tool that comes with three spoke nipple tools and one valve extender tool. It has three different sizes of slots that fit various types of square nipples found on bike wheels. The tool is made of hardened CRV tool steel, which ensures that the edges remain sharp and precise for a lifetime.

**Section 4: When to use a Spoke Wrench?**

You would use a spoke wrench when you need to adjust the tension of the spokes on your bike wheel. This could be because the wheel is wobbly or out of true. You may also need to use a spoke wrench to change a valve extender during a flat repair.

**Section 5: Practical Examples**

Let's say your bike wheel is wobbly and you suspect that the spokes are loose. You can use the Feedback Sports Spoke Wrench to tighten the spokes and bring the wheel back into true. First, you would loosen the nuts on the spokes using the wrench. Then, you would tighten them in a star pattern until the wheel is no longer wobbly.

Another example is if you get a flat tire and need to remove the inner tube. The valve extender on the tube may be stuck, and you can use the spoke wrench to loosen it before removing the tube.

**Section 6: Conclusion**

In this lesson, we learned about the Feedback Sports Spoke Wrench and its uses. We discussed how it works, when to use it, and provided practical examples. We also learned about the different sizes of slots on the tool and how it is made. By understanding the uses of tools like the Spoke Wrench, we can become more self-reliant and better prepared for various situations.

text: Starting in April 2010 contractors and remodelers are required to test paint for lead on any projects that they will be working on that are older than 1978 when lead paint was banned. Your contractor or remodeler will need to be licensed by the EPA. The EPA is scrambling to get applications processed and approved so delays of up to 90 days are not uncommon. If you have a project scheduled with a home remodeler and your project or home has not been updated since 1978 check with your remodeler to see if they have registered with the EPA. The Epa requires contractors to be certified in lead-safe work practices and training providers to be accredited by EPA. If they have not heard about the information you may want to pass this along: The application fee is $300 and the registration is good for 5 years. Contractors and remodelers can apply online This website contains tons of information about lead in paint for contractors and home remodelers.

Lesson: Gaussian Error Messages

Introduction:
In this lesson, we will learn about Gaussian error messages and how to troubleshoot them. Gaussian is a widely used software for quantum chemistry calculations. It can generate various error messages, which can be confusing for beginners. Understanding these error messages is crucial for successful calculations.

Section 1: Types of Gaussian Error Messages

1.1) Memory Allocation Problems: Gaussian may encounter memory allocation problems while running a calculation. This can occur if the input file is too large or if the system memory is insufficient. To fix this issue, you can try reducing the size of the input file or increasing the system memory.

1.2) Change in Point Group or Standard Orientation: Sometimes, Gaussian may report an error message indicating that the point group or standard orientation has changed during the calculation. This can happen due to changes in the molecular geometry. To resolve this issue, you can re-run the calculation with the correct point group and standard orientation specified.

1.3) Convergence Failure: Gaussian may fail to converge during a calculation, indicating that the desired accuracy has not been achieved. This can happen due to various reasons, such as insufficient basis set, incorrect level of theory, or poor starting point. To fix this issue, you can try increasing the basis set size, changing the level of theory, or using a better starting point for the calculation.

Section 2: Practical Advice for Quantum Chemistry Computations

2.1) Choice of Basis Set: The basis set is a crucial component of any quantum chemistry calculation. The choice of basis set can significantly affect the accuracy of the results. You should choose a basis set that is suitable for the problem at hand. For example, if you are working with small molecules, you can use a minimal basis set like STO-3G. For larger molecules or more complex systems, you may need to use a more extensive basis set like 6-31G*.

2.2) Choice of ab initio/DFT Methods: There are several methods available for performing quantum chemistry calculations, such as Hartree-Fock (HF), density functional theory (DFT), and post-Hartree-Fock methods like Møller-Plesset perturbation theory (MPn) and coupled-cluster (CC) theory. The choice of method depends on the type of system you are studying and the properties you want to calculate. For example, DFT is suitable for studying electronic properties of materials, while MPn and CC are more appropriate for studying excited states and reaction pathways.

Section 3: Common Hints on Quantum Chemistry Calculations

3.1) SCF Convergence: Stochastic convergence is a common problem in quantum chemistry calculations. This occurs when the calculation does not converge to the desired accuracy. To resolve this issue, you can try increasing the number of iterations or changing the level of theory.

3.2) Imaginary Frequencies and Saddle Points: Imaginary frequencies and saddle points can arise in quantum chemistry calculations due to numerical errors or instabilities in the calculation. To avoid these issues, you can use techniques like frequency cutoff or analytic continuation.

3.3) Optimization with Symmetry: When performing optimization calculations, it is essential to consider the symmetry of the system. If you do not account for symmetry, you may end up with incorrect results or unstable geometries. To resolve this issue, you can use techniques like symmetry-adapted coordinates or symmetry-adapted basis sets.

Conclusion:
In this lesson, we have learned about Gaussian error messages and how to troubleshoot them. We have also covered practical advice for quantum chemistry computations, including the choice of basis set and ab initio/DFT methods. Finally, we have discussed common hints on quantum chemistry calculations, such as SCF convergence, imaginary frequencies, and saddle points. By understanding these concepts, you can successfully perform quantum chemistry calculations using Gaussian software.

Lesson: Introduction to Mutagenesis and Antimutagenesis

**Objective:** To introduce students to the concepts of mutagenesis and antimutagenesis, and their applications in medicine and biotechnology.

**Glossary:**
- Mutagenesis: The process by which changes are induced in an organism's genetic material, often leading to alterations in its phenotype.
- Antimutagenesis: The process by which substances or agents prevent or reduce the mutagenic effects of other substances or agents.
- Mutation: A change in an organism's genetic material, usually caused by errors during DNA replication or exposure to mutagens.
- Antioxidant: A substance that prevents or slows down oxidation, a chemical reaction that can damage cells and tissues.
- Lipoxygenase: An enzyme that catalyzes the conversion of arachidonic acid into prostaglandins and leukotrienes, which play a role in inflammation and immune responses.
- Antimicrobial: A substance that kills or inhibits the growth of microorganisms such as bacteria, fungi, and viruses.

**Section 1: Introduction to Mutagenesis and Antimutagenesis**

Mutagenesis refers to the process by which changes are induced in an organism's genetic material, often leading to alterations in its phenotype. These changes can be caused by exposure to mutagens, which are substances or agents that can damage DNA and cause mutations. Antimutagenesis, on the other hand, refers to the process by which substances or agents prevent or reduce the mutagenic effects of other substances or agents.

**Section 2: Mutagenesis and Antimutagenesis in Medicine and Biotechnology**

Mutagenesis has several applications in medicine and biotechnology. For example, it can be used to create genetically modified organisms (GMOs) with desirable traits, such as resistance to pests or improved nutritional content. In medicine, mutagenesis can be used to develop new drugs and treatments for diseases, such as cancer. Antimutagenesis is also important in medicine, as it can help prevent the development of cancer and other diseases caused by mutations.

**Section 3: Practical Examples**

One practical example of mutagenesis is the use of CRISPR-Cas9 gene editing technology, which allows scientists to modify specific genes in living organisms. This technology has been used to create GMOs with desirable traits, such as resistance to pests and improved nutritional content. Another example is the use of radiation therapy to treat cancer, which works by damaging the DNA of cancer cells and causing them to die or stop dividing.

As for antimutagenesis, one example is the use of antioxidants to protect cells from damage caused by free radicals, which are highly reactive molecules that can damage DNA and cause mutations. Another example is the use of antioxidants in food preservation, which helps prevent the oxidation of fats and oils, which can lead to rancidity and off-flavors.

**Conclusion:**

In conclusion, mutagenesis and antimutagenesis are important concepts in medicine and biotechnology, with practical applications in areas such as gene editing, drug development, and food preservation. By understanding these concepts, students can gain valuable insights into the processes that govern life at the molecular level, and apply this knowledge to new problems and challenges.

Lesson: How to Access Locally Stored Images in Ionic

Introduction:
In this lesson, we will learn how to access locally stored images in an Ionic application. We will cover the following topics:

1. Why images are not displaying
2. Solutions to display images
3. Applying the solution
4. Conclusion

Why images are not displaying:
When you store images locally in your application, you may face issues while displaying them on the screen. This is because the application is not aware that new images have been added to the folder. To solve this issue, you need to trigger a digest cycle, which updates the application and allows it to render the new images.

Solutions to display images:
There are several ways to trigger a digest cycle and update the application. One of the simplest ways is to use the `$apply()` method. This method tells the application to run a new digest cycle and update the view.

Applying the solution:
To apply the solution, you need to add a small piece of code to your controller or service. This code checks if the current phase of the application is not `$apply` or `$digest`. If it is not, then the code triggers a new digest cycle by calling the `$apply()` method.

text: Review of Rimmel Sun Shimmer Bronzing Compact Powder (ALL) by ANGELiK. I've been using this bronzer everyday for a year now and I'm just now starting to see the metal bottom of the case. I apply it to my cheeks, nose and shoulders with a big blusher and it helps to give me a warm, healthy glow. I use more in the summer, to accent and even-out my tan and to warm-up my face in the winter. My only wish is that the lid to the compact was "snap-on" and not "screw-on"... that's just a pet-peeve of mine with all compact-cases. Otherwise, it's a very good, and cheap (under $10) product and I will definitely buy it again & again!

text: (professionymum: "căldare", Romanian: "cauldron"): originally makers and repairmen of cauldrons. They live in most of the countries of Europe and North and South America. Kalderaš speak a Vlach Romani dialect.. Source:. ROMBASE © by Milena Hübschmannová 2003. Kalderash uses a Romanes word (translated: boiler maker/smith") to describe the members of a Roma minority originally native to Southeastern Europe, who are said to have originated from the social group of blacksmiths. Many Kalderash (but also members of other groups) left the Romanian territories of Walachia and Moldova with the abolition of feudal ties - mostly serfdom, which could amount to slave status - from about 1840. In family groups, they migrated in all directions, including Central and Western Europe. Some of them emigrated overseas.. (c) Karola Fings/Ulrich F. Opfermann 2018

Q:

Why isn't the dispersion of the phonon spectrum of two atomic basis with equal masses the same as for the one atomic basis?

The solution for the two atomic basis is given by
\begin{align*}
\omega^{2}=\gamma\left(\frac{1}{M_{1}}+\frac{1}{M_{2}}\right) \pm \gamma\left[\left(\frac{1}{M_{1}}+\frac{1}{M_{2}}\right)^{2}-\frac{4}{M_{1} M_{2}} \sin ^{2} \frac{k b}{2}\right]^{1 / 2}
\end{align*}
but for $M_1 = M_2$ we have
\begin{align*}
\omega^{2}=\gamma\frac{2}{M} \pm \gamma\left[\left(\frac{2}{M}\right)^{2}-\frac{4}{M^2} \sin ^{2} \frac{k b}{2}\right]^{1 / 2} = \gamma\frac{2}{M} \pm \frac{2\gamma}{M}\cos \Big\vert \frac{k b}{2} \Big\vert
\end{align*}
which is only for the negative solution the same as
\begin{align*}
\omega(k) = 2 \sqrt{\frac{\gamma}{M}}\left|\sin \frac{k a}{2}\right|
\end{align*}
which is the solution of the one atomic chain and b=a/2. In every book I read they just state that it's the same and from a physical point of view it should, but mathematically I don't see a reason throwing away the $1+\cos(\dots)$ solution.

A:

When you move to a two-atom basis, you double the size of the unit cell and thus half the size of the Brillouin zone.* Say your one-atom cell has a width of one (i.e. $a=1$), so your two-atom cell has a width of two (i.e. $b=2$). In the former case, the Brillouin zone goes from $-\pi$ to $\pi$. In the latter case, the Brillouin zone goes from $-\pi/2$ to $\pi/2$. So you would expect the dispersion relation in the two case to be the same except for a fold: if you unfold the two-atom case, you get the one atom case.
You can see that in the below figure, which plots your last two equations in the reduced-zone scheme. If you take the part of the black curve (one-atom dispersion relation) where $\left|k/\pi\right|>1/2$ and fold it over at $k/\pi = \pm 1/2$, you'll get the dashed cyan curve.
In other words, you don't throw out the $1+\cos\left(...\right)$ solution; it's equivalent to the one-atom dispersion relation (black curve) for $\left|k/\pi\right|>1/2$. It may look like you can get away with only the $1-\cos\left(...\right)$, but that only works if you use a one-atom Brillouin zone with a two-atom unit cell, which is not a sensical thing to do. If you're using a two-atom unit cell, you're committing to a Brillouin zone with $\left|k/\pi\right|<1/2$.

** I think that the Brillouin zone is technically just for a primitive cell, and a two-atom cell with identical atoms is not a primitive cell. However, let's not go there.

textbook:
has a lattice constant 'a' and a mass 'M', so the two-atom cell has lattice constant 'a/2' and mass '2M'. The dispersion relation for the one-atom cell is given by:

$\omega(k) = 2 \sqrt{\frac{\gamma}{M}}\left|\sin \frac{k a}{2}\right|$

where $\gamma$ is the force constant between the atoms. When you move to a two-atom basis, you double the size of the unit cell and thus half the size of the Brillouin zone. So, the dispersion relation for the two-atom cell is given by:

$\omega^{2}=\gamma\left(\frac{1}{M_{1}}+\frac{1}{M_{2}}\right) \pm \gamma\left[\left(\frac{1}{M_{1}}+\frac{1}{M_{2}}\right)^{2}-\frac{4}{M_{1} M_{2}} \sin ^{2} \frac{k b}{2}\right]^{1 / 2}$

For equal masses ($M_1 = M_2$), the dispersion relation simplifies to:

$\omega^{2}=\gamma\frac{2}{M} \pm \frac{2\gamma}{M}\cos \Big\vert \frac{k b}{2} \Big\vert $

This is only for the negative solution the same as:

$\omega(k) = 2 \sqrt{\frac{\gamma}{M}}\left|\sin \frac{k a}{2}\right|$

which is the solution of the one-atom chain and b = a/2. In every book I read they just state that it's the same and from a physical point of view it should, but mathematically I don't see a reason throwing away the $1+\cos(\dots)$ solution.

*Note: The Brillouin zone is a hexagonal zone in reciprocal space that is defined by the diffraction pattern of a crystal. It is twice as large for a two-atom cell as for a one-atom cell.

Q:

how to calculate the total big O value of two algorithms -- is it just O(|f1| + f|2|)?

say I know the order of magnitude of both algorithms already -- for simplicities sake I will assume O(nLogn) and O(n^2).
is the answer just O(|nLogn| + |n^2|) or can I somehow get it into simpler terms?
I believe if I know the value of n, I could just plug it into the equation, since the total amount of work is the max running time of both.
i know its probably a a stupid question lol.

A:

I know its probably a a stupid question.

Not stupid, but it does indicate that you have not fully grasped what Big O notation means mathematically ... or intuitively.  You should go back to your lecture notes / textbook and reread what they say.
Intuitively, when we say that f(x) is O(g(x)) that means that f(x) tends towards being proportional to g(x) as x gets very big.
So for your example,

a(n) is O(nlogn) and b(n) is O(n^2)
a(n) + b(n) is O(nlogn + n^2)

but

O(nlogn + n^2) is the same as O(n^2), because as n gets very large, nlogn + n^2 tends to being proportional to n^2.  (The nlogn term gets relatively smaller until eventually it is no longer significant.)

so

a(n) + b(n) is O(nlogn + n^2) which is the same as O(n^2)

This can also be proven mathematically, if you are so inclined (or required).

Lesson: Introduction to Big O Notation

### Overview
In computer science, Big O notation is used to describe the performance or complexity of an algorithm. It is a way to measure the efficiency of an algorithm by estimating how long it will take to run on large input sizes. In this lesson, we will learn about Big O notation, how to analyze algorithms using it, and how to compare the performance of different algorithms.

### Section 1: What is Big O Notation?
Big O notation is a mathematical concept used to describe the performance of an algorithm. It is used to estimate the worst-case time complexity of an algorithm, which is the maximum amount of time the algorithm will take to run on a large input size. Big O notation is represented by the letter O followed by a function of n (the input size). For example, O(n) means that the algorithm's performance is directly proportional to the size of the input.

### Section 2: How to Analyze Algorithms using Big O Notation
To analyze an algorithm using Big O notation, we need to determine the worst-case time complexity of the algorithm. We do this by looking at the most time-consuming parts of the algorithm and determining how they scale with the input size. For example, if an algorithm has a loop that runs n times, its time complexity would be O(n). If an algorithm has a nested loop with a depth of log n, its time complexity would be O(log n).

### Section 3: Comparing Algorithm Performance using Big O Notation
To compare the performance of different algorithms, we look at their Big O notation. The smaller the Big O notation, the better the performance of the algorithm. For example, if we have two algorithms A and B with time complexities of O(n) and O(n^2) respectively, we would choose algorithm A because it has a better performance.

### Conclusion
In this lesson, we learned about Big O notation, how to analyze algorithms using it, and how to compare the performance of different algorithms. By understanding Big O notation, we can make informed decisions about which algorithms to use based on their performance.
