In this episode of Mathematics Simplified, we dive into the world of complex numbers! Join us as we break down what complex numbers are, why they're important, and how they're used in mathematics and beyond. We'll explain the basic form of a complex number and walk through simple operations like addition and multiplication. Plus, we'll cover key concepts like the conjugate and modulus of a complex number. Whether you're new to complex numbers or just need a refresher, this episode is designed to make these concepts clear and approachable!
Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: An Introduction To The Mandelbrot Set That Doesn't Mention Complex Numbers, published by Yitz on January 17, 2024 on LessWrong. Note: This post assumes you've heard of the Mandelbrot set before, and you want to know more about it, but that you find imaginary and complex numbers (e.g. the square root of negative one) a bit mystifying and counterintuitive. Instead of helping you understand the relevant math like a reasonable person would, I'm just going to pretend the concept doesn't exist, and try to explain how to generate the Mandelbrot set anyway. My goal is for this post to (theoretically) be acceptable to the historical René Descartes, who coined the term "Imaginary number" because he did not believe such things could possibly exist. I hereby formally invite you to a dance. Since we're (presumably) both cool, hip people, let's go with a somewhat avant-garde dance that's popular with the kids these days. I call this dance the Mandelbrot Waltz, but you can call it whatever you'd like. This dance follows very simple rules, with the quirk that your starting location will influence your part in the dance. You will unfortunately be cursed to dance forever (there's always a catch to these dance invitations!), but if you ever touch the edges of the dance floor, the curse will be lifted and your part in the dance ends, so it's really not all that bad... In case you don't already know the moves, I'll describe how to do the dance yourself (if given an arbitrary starting point on the dance floor) step-by-step. How To Perform The Mandelbrot Waltz: A Step-By-Step Guide Preparation: You will need: Yourself, an empty room, and a drawing tool (like chalk or tape). Setup: Draw a line from the center of the room to the nearest part of the wall, like so: Now, draw a circle around the room's center, such that it intersects the "orienting line" halfway through. It should look something like this: Starting Position: Choose a starting point anywhere you want in the room. Remember this position - or jot it down on a notepad if your memory is bad - for later. Step 1 - Rotation Doubling: Imagine a line connecting your current position to the center of the circle: Find the orienting line we drew on the floor earlier, and measure, counterclockwise, the angle between it and your new imaginary line. Rotate yourself counterclockwise by that same angle, maintaining your distance from the center, like so: It's okay if you end up making more than a full 360° rotation, just keep on going around the circle until you've doubled the initial angle. For example (assuming the red point is your original position, and the black point is where you end up): It should be intuitively clear that the further counterclockwise your starting point is from the orienting line, the further you'll travel. In fact, if your starting point is 360° from the orienting line--meaning you start off directly on top of it--doubling your angle will lead you 360° around the circle and right back to where you started. And if you have a lot of friends doing Step 1 at the same time, it will look something like this: Step 2 - Distance Adjustment: Imagine a number line, going from 0 onward: Take the number line, and imagine placing it on the floor, so that it goes from the center of the room towards (and past) you. The end of the line marked with number 0 should be at the center of the room, and the number 1 should land on the perimeter of the circle we drew. It should look something like this: Note the number on the number line that corresponds to where you're standing. For instance, if you were standing on the red dot in the above example, your current number value would be something like 1.6 or so. (I totally didn't cheat and find that number by looking at my source code.) Now, take that number, and square it (a.k.a. multiply that n...

A story about a man of the XX century who got into the XXII century through cryofreezing. The new society considers itself a utopia and a Paradise on Earth. But from the point of view of the values of the XX century, it also has a dystopian feature: the destruction of the concept of personality and individuality. And so deep and cunningly grounded that Zamyatin, Huxley and Orwell smoke on the sidelines. Music: Andrey Klimkovsky, Viktor Argonov. Text, arrangement: Viktor Argonov.

The SEAN for SCIENCE Podcast is targeted at a thoughtful, general audience. Our first season, How to Solve the Schrödinger Equation, will offer a physicist's tour of the microscopic. It's my take on a modern introduction to Quantum Mechanics, braided with my own experiences and stories that led to my perspective on the subject. This initial episode, Chapter Zero, looks at a the first necessary but unfamiliar ingredient to our story, the Complex Numbers.
Complex Networks is reportedly on track for $200 million in revenue this year. In this episode, Baesler provides a deep dive on the company and its portfolio of media brands and events focused on sneaker culture, hip hop and food.

Much is written about life as an undergraduate at Oxford but what is it really like? As Oxford Mathematics's new first-year students arrive (273 of them, comprising 33 nationalities) we thought we would take the opportunity to go behind the scenes and share some of their experiences. Our starting point is a first week lecture. In this case the second lecture from 'An Introduction to Complex Numbers' by Dr. Vicky Neale. Whether you are a past student, an aspiring student or just curious as to how teaching works, come and take a seat.

This podcast is about Complex Numbers. Christian tells why you need them - actually are Complex Numbers the Gaffa Tape of the Mathematics
We exploit the analogy between complex numbers and 2 by 2 matrices to perform complex number reciprocals and division.
In episode #449, Bart Busschots walked us through how he'd solve the first half of the JavaScript challenges from PBS 19. This week we finish the second half of the 5th problem about Complex Numbers. Like the last episode, we're giving you the audio in the podcast, but if you'd like to watch the video of Bart building the solutions, you can see that over on podfeet.com.
What do you get when you put a real and an imaginary number together? A complex number. No, not a complicated number (although it kind of is), we’re talking about an entirely new set of numbers dubbed “complex.” Read the full transcript here: http://bit.ly/1JLrpJk
A teaching assistant works through a problem on complex numbers and Euler's formula.
Introduces the exponential form for a complex number and demonstrates how this is consistent with the multiplication/division rules in modulus/argument form as well as interpretations as a scaling/rotation operator.
Looks at the computation of square roots using complex number algebra. This uses simple problems to establish an approach to such problem solving which subsequently can be applied to more complex root problems.
Shows how the rules for multiplication/division in modulus/argument form lead to a very useful interpretation of complex numbers as scaling and rotation operators. This is used to solve problems in many engineering scenarios. Obvious typo at 7min 30 where writing uses 110 instead of 100.
A number of questions for students to test their understanding of the videos in this series followed by worked solutions.
Introduces fast methods of complex number division using the modulus/argument form. Spends sometime 'demonstrating' the vailidity of the result, although viewers could focus on just the result should they choose.
Introduces fast methods of complex number multiplication using the modulus/argument form. Spends sometime 'demonstrating' the vailidity of the result, although viewers could focus on just the result should they choose.
Introduces the concepts of modulus and argument. Also spends some time showing how the modulus and argument of conjugates and inverses are related to the orginal complex number.
A rapid review of complex numbers as would be covered in introductory lectures. Thus definitions, the Argand diagram, simple multiplication, division and addition and complex conjugates.
Shows how to solve for cube roots, 4th roots and so on of complex numbers. Makes use of De Moivre's Theorem, but the focus is on a simple presentation style which shows why the result works.
Gives the general formula then applies this to an example. Cartesian form is convert to polar form, then the required power of the number is calculated, and finally the result is converted back into Cartesian form.
We show how complex number arithmetic can be performed using matrices for the complex numbers.
The conditions for equality of complex numbers are given. An example of grouping and then equating real and inaginary parts of complex numbers on both sides of an equation to find unknown quantities is then given.
Math 103-College Algebra
For many applications we find that it is much easier to represent our physical quantities in terms of complex numbers rather than just using real numbers alone. The concept of complex numbers comes from the continuation of functions such as square-root and logarithm that only apply to positive numbers in their traditional definitions. Figure 1 shows the function √ x. Other functions like ln x, sinx, etc., also have limits on their arguments, and complex numbers allow us to define these functions over the full range of real numbers.
The general formulae for multiplication and division of complex numbers in polar form are given and their use is then demonstrated in relation to a particular example
The general principle is explained of how to divide one complex number by another when both numbers are written in Cartesian form, so that the denominator of the final answer is a real number. A specific example of using this process is then given.
Through an examples shows how to multiply complex numbers introducing the powers if i such as i^2.
Calculus Revisited: Calculus of Complex Variables, Differential Equations, and Linear Algebra
Through a couple of examples shows how the addition and subtraction of complex numbers in cartesian form works
You may have met complex numbers before, but not had experience in manipulating them. This unit gives an accessible introduction to complex numbers, which are very important in science and technology, as well as mathematics. The unit includes definitions, concepts and techniques which will be very helpful and interesting to a wide variety of people with a reasonable background in algebra and trigonometry. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University. Published in ePub 2.0.1 format, some feature such as audio, video and linked PDF are not supported by all ePub readers.
This unit extends the ideas introduced in the unit on first-order differential equations to a particular type of second-order differential equations which has a variety of applications. The unit assumes that you have previously had a basic grounding in calculus, know something about first-order differential equations and some familiarity with complex numbers. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.
