There are a number of collections that are like this — collections that aim to demonstrate science concepts in a way that is easily digestible. Each is unique in its own way, and I really encourage you to spend some time Google-ing about and finding all the various lists, as many of them are terribly informative.

Here, full disclosure, we tried to trace down the original source. This means that, if we found something on Reddit, we did a reverse image search to trace down the original creator and original appearance (and listed the credits as such).

Anyways, we hope you enjoy the show.

1) This is a Reuleaux Triangle

There are curves of constant width besides circles and spheres. It's a convex planar shape whose width is the same regardless of the orientation of the curve.

3) This Is Why Pi Is Significant

This animation shows the act of unrolling a circle's circumference (or trying to), illustrating the ratio π.

4) This Is How to Make Pascal's Triangle

These are used in algebra and probability, where it can be used to find Combinations.

5) This Is a Miura Fold

It's a method of folding a flat surface into a smaller size. It consists of tessellated parallelograms and is used in the solar panels of satellites.

6) This Is a Parabola

If you kick a soccer ball (or shoot an arrow, fire a missile, or throw a stone), it will arc up into the air and come down again...following the path of a parabola!

7) This Is a Radian

The radian is the standard unit of angular measure, used in many areas of mathematics.
