Hey Bill Nye, ‘How Will Quantum Mechanics Change the World?’
Bill Nye   Apr 3, 2016   Big Think  

Echoing Bill Nye’s favorite phrase, Tom from Western Australia asks after the practical implications of quantum mechanics. It’s a tough sell, explains Nye, but computing power is on the short list. The imaginable benefits of quantum entanglement, called “spooky action at a distance” by the skeptical Albert Einstein, lie further afield. Nye thinks with our knowledge of subatomic particles it is theoretically possible to harness the energy created by black holes and perhaps even travel backwards in time.

 




COMMENTS
Thanks to Bill and Tom for an engaging exchange.

The interested reader is encouraged to have a look at JS Bell's collection of witty essays, 'Speakable and Unspeakable in QM.'

Here's a highly salient excerpt:

"But in 1952 I saw the impossible done. It was in papers by David Bohm. Bohm showed explicitly how parameters could indeed be introduced, into nonrelativistic wave mechanics, with the help of which the indeterministic description could be transformed into a deterministic one. More importantly, in my opinion, the subjectivity of the orthodox version, the necessary reference to the ‘observer,’ could be eliminated. ...

But why then had Born not told me of this ‘pilot wave’? If only to point out what was wrong with it? Why did von Neumann not consider it? More extraordinarily, why did people go on producing ‘‘impossibility’’ proofs, after 1952, and as recently as 1978? ... Why is the pilot wave picture ignored in text books? Should it not be taught, not as the only way, but as an antidote to the prevailing complacency? To show us that vagueness, subjectivity, and indeterminism, are not forced on us by experimental facts, but by deliberate theoretical choice?"
