20 Gifs That Teach You Science Concepts In Seconds

by Jolene Creighton
There are a number of collections that are like this—collections that aim to demonstrate science concepts in a way that is easily digestable. 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, I tried to trace down the original source.This means that, if the first result that popped up was reddit, I did a reverse image source to trace down the oldest version that I could find. If the oldest source didn't explain what was being demonstrated, I c cited the source of the gif and found another source to clarify.
If you want to know more about the people behind FQTQ and what we are about, head here. And I hope you enjoy the show.


1) This is a 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)

2) And these Curves of Constant Width can drill square holes

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)
