IFM: Interaction Free Measurement
Answer to HW1 problemhttp://logicaltightrope.com/2013/08/13/seeing-without-looking-the-quantum-bomb/
Uncertainty
Anotações:
Universe in very real sense, unknowable
Heisenberg
Anotações:
E= ~hw, p=~hk; ~h = h/2pi
dx*dp \> h
Trans:
If you pinpoint the position of a specific particle, then you won't be able to precisely measure its momentum.
And if you precisely measure a particles momentum, then you cannot know its exact position
Also, if we try to measure the momentum of the wave, this uncertainty shows up with how accurately we can measure it - classical mechanics fails at this point.
Planck's
length
(h)
Feynman quote
Anotações:
"Yes! physics has given up. We do not know how to predict what would happen in a given circumstance, and we believe now that it is impossible - that the only thing that can be predicted is the probability of different events.
Wave Particle duality
Waves
Wave eqation
Schroedinger Equations
Operators
Anotações:
A mapping between vectors; A vector function
hermitian
Anotações:
A linear vector operator
Hilbert Space
Anotações:
Complex-valued linear vector space; Complete space w/ an inner product
Inner Product: generalized dot product (?)
Particles
Anotações:
Individual particles unpredictable; lots of them follow statistical/ probabilistic laws
Feynman quote
Anotações:
exhibits different behavior at different frequencies
