"To avoid criticism do nothing, say nothing, be nothing.."
(Elbert Hubbard)


I studied Physics at the University of Vienna, but I'm interested in all natural sciences.

Since I don't believe in life after death I try to explore and learn as much as I can about this world.

comment Why did the process of sleep evolve in many animals? What is its evolutionary advantage?
e.g. dolphins can't afford to lose full consciousness when they rest, otherwise they would drown. So their mammalian brains have evolved in such way that only one half of the brain sleeps at a time.
