Article 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 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, I tried to trace down the original source. This means that, if I found something on Reddit, I did a reverse image search to trace down the original creator and original appearance.
