## Sine waves explained through a story

Articles, Blog 100 CommentsHi I’m Toby and welcome back to the Joy of Mathematics, I’m so glad you could join me today. I’ll run some ideas across the bottom of the screen that we are going to encounter during a story today. I’d also like to thank this episode’s sponsor Brilliant.org. So today’s story is another one about

## What is quantum mechanics really all about?

Articles, Blog 100 CommentsFor the most part, physics is a pretty straightforward discipline. While the math might be complicated, physics is often about quantifying such things as “what goes up, must come down” and “don’t play chicken with a train.” Statements like those are intuitive and pretty much everyone can get their head around them. But, over the

## Creating Circular Motion from Sine and Cosine Curves

Articles, Blog 4 CommentsMr. P: Good morning. Let’s start with a dot moving in the y-direction in simple harmonic motion, just like a vertical mass spring system. Flipping Physics If we set the dot in motion at a constant velocity to the right, Bo what sort of function does that create? Bo: That looks just like a sine

## Fourier Transform, Fourier Series, and frequency spectrum

Articles, Blog 100 CommentsWe have an X axis and a Y axis. Let us also create an axis that represents the angle theta. The green line rotates by the angle theta. For each value of theta, the X coordinate represents the cosine of theta, and the Y coordinate represents the sine of theta. The angle theta can range

## Why sin and cos don’t mean anything

Articles, Blog 100 CommentsThis is candy. It’s called candy because it was originally from India, where sugar cane was first processed into sugar crystals around the 4th century AD, with a piece of sugar referred to as ‘khanda’ (खण्ड) in Sanskrit. *Simon surreptitiously deposits the candy into his mouth* Now, as the knowledge of the cultivation and processing

## Theoretical physics: insider’s tricks

Articles, Blog 100 CommentsPhysics is the simplest and most central of all branches of human knowledge. I know that. You know that. Everybody knows that. And it’s true! Of all of the branches of physics, the truly deepest and most fundamental of all is particle physics. Our current theory, which is called the Standard Model, is based around

## A Problem to Review SOH CAH TOA and the Pythagorean Theorem for use in Physics

Articles 6 CommentsBo: Hey, guys. Billy: Hey, Bo! Bobby: Hi, Bo. ♫ (lyrics) Flipping Physics ♫ Mr. P: Ladies and gentlepeople. The bell has rung,therefore class has begun. Therefore, you shouldbe seated in your seat, ready and excited to review SOH CAH TOA, and the Pythagorean Theorem. Billy: Oh, boy! Bo: Shouldn't we already know those. Mr.
