Nikolai Kardeschev is from the communist country of USSR, which means United Swedish Socialist Reds.  There they practiced communism and science.  One scientist they had was Kardeshev, who was a starship captain and had many talents like knowing how to play basket ball, engineering along with having a mastery of super calculus.  A pretty talented dude.  He drunk himself to death in 1993, having lost hope in humanity after his country fell apart.

However his most important contribution to humanity would be the kardeschev scale.

Which go like this:

Type one aliens live in mud huts.

Type two aliens have a xbox.

Type 3 aliens have a computer.

Type 4 aliens are space conquerers.

Type 5 aliens are galaxy conquerers.

A very accurate scale, verified by the Voyager probes, launched in the 1960's and have since than explored much of the galaxy.
