Feynmans brilliant defiantly my favourite scientist

you can download his lectures and you can understand them with not a huge amount of knowledge on the subject

same I'm no expert but its propbably my favourite genre of physics

anybody got a favourite part and quantum or something they find about wow

Yes,

I tried Heisenbergs uncertainty principle last time I was stopped for speeding:

"Do you know how fast you were going, sir?"

" no, but I know where I am"

Didn't do me much good.

Laplace's vision, of scientific determinism, involved knowing the positions and speeds of the particles in the universe, at one instant of time. So it was seriously undermined by Heisenberg's Uncertainty principle. How could one predict the future, when one could not measure accurately both the positions, and the speeds, of particles at the present time? No matter how powerful a computer you have, if you put lousy data in, you will get lousy predictions out. 

Einstein was very unhappy about this apparent randomness in nature. His views were summed up in his famous phrase, 'God does not play dice'. He seemed to have felt that the uncertainty was only provisional: but that there was an underlying reality, in which particles would have well defined positions and speeds, and would evolve according to deterministic laws, in the spirit of Laplace. This reality might be known to God, but the quantum nature of light would prevent us seeing it, except through a glass darkly. 

Einstein's view was what would now be called, a hidden variable theory. Hidden variable theories might seem to be the most obvious way to incorporate the Uncertainty Principle into physics. They form the basis of the mental picture of the universe, held by many scientists, and almost all philosophers of science. But these hidden variable theories are wrong. The British physicist, John Bell, who died recently, devised an experimental test that would distinguish hidden variable theories. When the experiment was carried out carefully, the results were inconsistent with hidden variables. Thus it seems that even God is bound by the Uncertainty Principle, and can not know both the position, and the speed, of a particle. So God does play dice with the universe. All the evidence points to him being an inveterate gambler, who throws the dice on every possible occasion.

I loved it since my days of startrek the next generation.

I bought a book by paul davies, the last three minutes which was great..then stephen hawking's an illustrated brief history of time, the the periodicals such as new scientist.

I'm absoultely shit at the math..but in the end..all I've seen is that all of them agree there is something more than plain physics can explain..

my newest theory is that the inhabitants of 'a' universe need to be almost immortal beings(or lets say a transmoglification of biological to technological)..then send the information of their source codes into black holes...

I just see this rule of entropy being the crux of life..unless we understand what zero point energy is(will we ever?)

I even think on the spiritual level about it all i suppose..

why does hitler still influence us..he is dead..his energy is 'gone'...why do we remorse over the dead if they are in an afterlife?

is the afterlife just another dimension..that we ourselves create(and that means its essentially 'real'..given the quantum world.

anyway topping it all off..it might have been seen..but if we are all in bubble universes it all seems to me that when we look at the smallest to the largest...we might just see things that echo our own experiences...a microbes world...really might not be that far from our perceivable existence or theirs..

Incoherence or decoherence? "

Incoherence has been pretty fun tonight, gotta admit.

Get Ziggy to compute the equation

Haha.

Good idea though, maths isn't my strong point.

Im interested in the engineering outcomes of our advances in quantum mechanics (quantum computers or entangled photons potentially instantaneous communication from any where with perfect signal, no satelites, or masts needed)

I ave heard some as says you can't communicate using entaglement cos whist general relativity don't say nothing can go faster than light it does forbid the echange of info faster than light. Also you never know the state of entagled pairs.

We've already done it.

1.2km iirc not sure if it actually worked out faster than light though

And of course you can know the spin of them, you need to know it to change it :p

I don't think they were communicating,but did set a distance record while displaying non-locality.

Is a particularly mindfucking example of entanglement

Separation was to prove signals were not travelling between detectors causing false correlations.

Faster than light communication would violate the second law of thermodynamics. Heat would travel from cold to hot in a way we never see particularly in maps of the background radiation from the big bang.

"Feynmans brilliant defiantly my favourite scientist

you can download his lectures and you can understand them with not a huge amount of knowledge on the subject

same I'm no expert but its propbably my favourite genre of physics

anybody got a favourite part and quantum or something they find about wow"

Best explanation of the double slit experiment I ever heard. I quite like his diagrams as well

The origin of matter… how can something appear from nothing? If nothing is actually not nothing, it is something. Will humanity ever be able to discover the actual origin of matter? If matter came from energy, where did energy come from initially?

one of the questions which exercise theoretical ohysicists. They javeent resolved the known universe yet, perhaps when that has been done the question of what came before this and the the big bang will be next.

Quantum Entanglement has fascinated me since learning about it. The idea that two particles at opposite ends of the universe could potentially mirror any effect on the other one, blows my tiny little mind

Unfortunately Cox believes in MWI, the 'many universes theory'. And as someone once said, "that's not even wrong"!
