• A reply on Talk: Aaron O'Connell: Making sense of a visible quantum object

  Jun 10 2011: He says that even if this is macroscopic compared to the microscopic world that we experience quantum mechanical phenomena, this still does not justify telepathy.
  
  In qm, wave function of an object does not go to zero (except for some unrealistic infinite square well excercises) so there are interactions between very very distant objects, but thay are still too faint to be considered as significant.

  Jun 10 2011: I quote this from xkcd "Space-time is like some simple and familiar system which is both intuitively understandable and precisely analogous, and if I were Richard Feynman I'd be able to come up with it." (http://xkcd.com/895/)

• A reply on Conversation: Refuting a quantum mechanics theory

  Jun 10 2011: Even if you measure all those things, which you can, there is certainly a probabilistic behaviour inherent to the system. Coin toss is just an example. You can use fluctuations in the ionisphere, or noise in an electronic circuit.
  
  Your "refutation" was considered after unveiling of quantum theory, even by Einstein (infamuos "god does nit throw dice" quote), there were people that argued there are some "hidden variables" that we don't know. We now know that these assertions are not true.
  
  Famous EPR "paradox" was proved to be a wrong hypothesis experimentally.

  A comment on Conversation: Refuting a quantum mechanics theory

  Jun 7 2011: Even if every action in the universe had only two outcomes (just like a coin toss), this wouldn't be true. Because each coin toss could either go one way or other and this alone could change the final result.

  Jun 7 2011: If you have access, the detailed explanations of the experiments they have done are shown in here: http://www.nature.com/nature/journal/v464/n7289/full/nature08967.html
  
  Also there is a Science coverage of the news http://www.sciencemag.org/content/330/6011/1604.full but the good juicy part is in the original Nature paper.

  Jun 7 2011: There are single photon experiments for quantum circuits. A single photon interferes with itself. We don't argue that a particle X exists because then the theory side changes and this changes the expected results.
  
  So this particle X must be some weird thing that satisfy both mathematics and the results of the experiments. Now, this may seem a way to go but, why invent something if one more reasonable and simple thing explains the system.
  
  Also quantum theory scales to many body problem very nicely. So this is another strong evidence that this theory is right.
  
  There are somethings unknown, but may be that's because we are too used to think in classical terms; we expect to see classical results.

• A comment on Talk: Evan Grant: Making sound visible through cymatics

  Oct 16 2009: Those patterns are standing wave solutions to some differential equations applied to various boundary conditions. A square lattice for example. So every physical phenomena with the same differential equation and a wave behavior can produce such patterns. Light propagating in fiber for example.

• A comment on Talk: Tom Honey on God and the tsunami

  Jul 2 2007: In muslim perpective, there are six pillars of faith, one of which is to believe that all good and bad things happened are from the God. So he tests peoples faith with these kinds of cathastrophies. Because, this life is not the life we should be happy, since it won't last long, we must be prepared for the other life.
