Statistical physics:
a journey through randomness

Florian Angeletti

The "rules" of physics

Quantum mechanics
(small scale)
Classical mechanics
(medium scale)
General relativity
(large scale)

Statistical physics:
a strategy

for system with very large number of particles

A room full of air

~one octillion (100000000000000000000000000) molecules
  • One particle:
    hand computation
  • 1000 particles:
    computer simulation
  • Either at the front or the back
  • Front or back: same probability
  • Add particles one by one
Will it ever goes home?

Almost surely

(with an infinite amount of time )

Traffic jam-like model

Extreme events

Thank you for your attention
