Quantum Physics

  1. Why, because I supported the Bible and its pkace
     
  2. Why do you ask ? Did I say something that you didn't like?
     
  3. Why are you so frightened of simply calling things "true" and "untrue"? Those words have ordinary, well-known meanings and I have no difficulty in saying that scientific facts for which there is good evidence are true. Newton's theory of gravity was true within the ambit of the facts with which it dealt, and it has not become false because Einstein later produced more elaborate theories accounting for more extreme situations (which are also true). Just because scientific facts are in principle falsifiable does not mean they are not true. Religionists continually describe as "true" assertions based on no evidence at all; those are the things I have no hesitation in calling untrue.

    What do you mean by "chance"? This is rather like saying that if a hallucinating mental patient says he can see pink dragons, isn't there a teeniest chance that the dragons might actually exist? Well no, there isn't. Chance is not the issue. Delusions, errors, misunderstandings, and lies do not correspond with reality - not a chance.

    What do you mean by a "possible explanation"? The notion of god explains nothing. Anything for which we humans have no explanation, still has no explanation by merely asserting god. The god concept serves only to get in the way of searching for real explanations, just as it always has done.

  4. You seem to be frightened of saying things are true or untrue. Why is that?
     
  5. There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know.

    Donald Rumsfeld

    I cannot say with absolute certainty what I don't know, even things that are highly improbable can still fall into that category.

    Quantum entanglement breaks the law that says nothing, even information, can travel faster than the speed of light, that opens up a potentially large area of what we don't know we don't know.

    Are we a computer simulation ? If so who is running the simulation ?

  6. Absolutely neither.
    I haven't got more than an O Level in either - even if it was Grade A :)

    I'm just interested and have read more books on physics (not that many, clearly) than I ever did when I was made to study the subject.
     
  7. There is only Physics, of which everything else is a sub set.

    Who said that ?
     
  8. Sheldon.
     
    • Thanks Thanks x 1
  9. Likewise. Just Maths & Physics O levels at grade 1. Still interesting though.
     
  10. OK, I did get A/O level maths at grade A too, but that's pretty much bugger all use for understanding the maths in quantum mechanics!

    A bit like trying to build a nuclear reactor when your only engineering experience is Lego.

  11. Hugh Everett III, father of Mark Oliver Everett, or E, of EELS fame, was a brilliant young mathematician who went to a lecture given by Niels Bohr on Quantum Mechanics and listened to the theories being presented. He came up with a alternate interpretation which is now known as the Multiverse, where constant branching creates an infinite number of universes where anything and everything is possible. He presented this hypothesis to the physicists of the days and was ridiculed for his ideas and he disappeared into the military industrial complex to work in atomic weapons research. The Multiverse is now a widely accepted hypothesis.

    Maybe quantum entanglement hints at the ability to pass information in ways we cannot comprehend, maybe there is something out there that we are simply incapable of seeing or understanding ?
     
  12. fuckwits, higher math for me.

  13. "We"? You speak too soon. 200 years ago there were loads of things which nobody could comprehend, and which some people said 'we' were incapable of understanding. Some of those things are now understood by every schoolkid. 200 years in the future loads of things incomprehensible now will be commonplace.

  14. We were taught basic particle physics at A level, one of our teachers worked at CERN and took it on herself to teach us even though it was not on the syllabus. she even arranged a trip there for us while it was being converted from an election collider into the LHC.
    If anyone gets a chance to visit it is well worth the trip.

  15. I've looked into it, as it's only down the road (well, say 40 miles).
    I'd better look into it more.

  16. It's fascinating there especially if you are interested in the subject. It's a seriously impressive engineering feat too.
     
  17. Er what's that, detention
     
  18. @Evoarrow kind of like an o level but harder.
     
  19. I refer you to the Martin Rees quote about ants on the Empire State Building, maybe there are limits to what our, and even your, brain is capable of comprehending ;)
