What If?

In 2005, NASA employee Randall Monroe created the site xkcd.com and began to publish funny comics.
The comics were simple but expressive, they also had an explanation. Themes were pretty smart.

The site turned into a blog What If? Where Randall Monroe answered questions on physics.
The questions were simple, children's, but the answers are detailed and understandable - links to sources, calculations.
