How do we know it's not set if we can't tell what value it has until we measure it?

comment Is it possible to use quantum mechanics for an effective time based encryption?
Maybe consider asking this question on the cryptography stack exchange...

comment Is it possible to use quantum mechanics for an effective time based encryption?
It took some thinking and researching but I understand the motivation behind his question also. It's a good question. This question crypto.stackexchange.com/questions/606/… gives more background on Time-based crypto. The only thing I can think of in QM that is 'predictably' time-dependent is radioactive decay...

comment Why does Quantum Electrodynamics Allow a Photon to Exist Temporarily as a Positron and an Electron?
I understand it's "allowed" but not where the rules come from that allow it... I'm missing something fundamental about why the photon would do this and not just stay a photon...

comment Why does a photon colliding with an atomic nucleus cause pair production?
Accepted because of the nice explanation of the electron-positron virtual particle situation with the photon. I think I'm going to ask a more pointed question about this soon. Thanks!

This looks like a book about non-mainstream physics... Not the best way to answer a question about mainstream physics.

@dmckee Right, I'll keep that in mind for the next question. I tend to do that in my questions I guess. I think I'm trying to create a picture of the gap I'm trying to fill. Asking multiple questions, to me, helps define the gap. But it also makes it harder to answer as you said. I'll try to be more to-the-point next time.

comment Why does a photon colliding with an atomic nucleus cause pair production?
Can you expand on this part? "However, if an atomic nucleus is near by, then it is possible that a second photon coming from the nucleus can separate the two particles, before they annihilate again to give the original photon that generated them. I.e. the Coulomb field of the nucleus “pushes” the positron away, while it “pulls” the electron towards it. Hence the two particles became real, and can be guided into magnetic fields for storage and further use." Thanks!

@twistor59 I guess if we could understand the "why", we'd have a much deeper understanding of Physics...
