So astronomer Tycho Brahe's body has been being exhumed (again) for scientific testing.
It seemed a perfect excuse to make a video about this famous and eccentric scientist.
But what symbol would represent him on the Sixty Symbols website.
To me, the solution was obvious?
Tycho also lends his name to perhaps the most identifiable crater on the Moon.
Films buffs may know that the crater Tycho is where the monolith is discovered in the film 2001: A Space Odyssey.
It also pops up in other books and movies.
