Prediction of the Neutrino
Standard Model of Particle Physics
Bosons - forces
g electromagnetic force (charged particles)
W , Z 0 weak force (e.g. beta decay, all particles)
Gluons strong force (quarks, ‘colored’ particles)
graviton gravitation (all particles)
380 000 years:
Big Bang and the early Universe
T = 0.2 mK
Cosmic Microwave Background
– low density
– high density
Curvature of Space
Ω < 1
– “critical” density
Ω = 1
Ω > 1
(Heisenberg reporting): Bohr's thoughts combined themselves for me with the ... view that atoms are not anymore things. Even though Bohr believed to recognize many details of the inner structure of the chemical atoms, the electrons that made up their shells obviously were not things anymore, certainly not things in the sense of the old physics that could be described without reservation in terms of position, velocity, energy, or extension.So I asked Bohr: "If the inner structure of the atom is so little approachable as you say, if we do not really have the language to talk about this structure, will we ever be able to understand the atoms?" Bohr paused for a moment before he answered: "Yes. But at the same time we will learn what 'understanding' means".
