I like physics because it explains how stuff works.

Sep 16	comment	How does space affect the human body (no space suit, no space craft) I always thought a person would explode in space if he didn't have a space suit, because there is no pressure on your skin to hold your organs in.

Sep 12	accepted	Does Heisenberg's energy-time uncertainty principle imply that quantum computing is no more efficient than classical computing?

Sep 6	comment	Does Heisenberg's energy-time uncertainty principle imply that quantum computing is no more efficient than classical computing? If you look at the arxiv time stamp, it was posted in 2000. All of the citations are before 2000. I'm not sure why it says 2008 in the paper.

Sep 5	comment	How Does Mass Leave the Body When you Lose Weight? What about the fastest way to lose weight, having a baby?
Sep 5	comment	If quantum mechanics is ultimately deterministic, would Shor's factorization algorithm still work for large integers? After thinking more about what you said, I conclude that it's a great answer. Thank you!

Sep 5	comment	What should a physics undergrad aspiring to be a string theorist learn before grad school? See staff.science.uu.nl/~hooft101/theorist.html
Sep 3	comment	If quantum mechanics is ultimately deterministic, would Shor's factorization algorithm still work for large integers? Why do you say that Victor Stenger's writing isn't important? I thought it is very well written and very important.
Sep 2	comment	If quantum mechanics is ultimately deterministic, would Shor's factorization algorithm still work for large integers? Thank you Nick. That's good, but I'd like to see more detail in an answer. Hopefully, someone will provide more detail.
Sep 2	comment	If quantum mechanics is ultimately deterministic, would Shor's factorization algorithm still work for large integers? Can you point to the thread?

Sep 2	comment	Why do some physicists believe that scalable quantum computing is possible? That's what I believe and have always believed. But I haven't been able to prove it.
Aug 31	comment	Why do some physicists believe that scalable quantum computing is possible? I think Einstein made sense when he said "God doesn't play dice." That's why I think QM will break down for scalable quantum computing. I think the randomness is not true randomness. It's just a result of us not knowing enough about the system.
Aug 31	comment	Why do some physicists believe that scalable quantum computing is possible? This whole thing is very confusing to me. I'll have to concede now that I think quantum mechanics must break down once you get things to be on the level of scalable quantum computing. There's just no way I can conceive of it working. Thank you for your answer.
Aug 31	comment	Why do some physicists believe that scalable quantum computing is possible? @RonMaimon Can you post your proposal for a hidden variable scheme?
Aug 31	comment	Why do some physicists believe that scalable quantum computing is possible? @RonMaimon That seems to be the consensus among physicists who believe in quantum computing. Then I guess I'm one of those people who believe that quantum mechanics is not exact. Thank you very much.
Aug 31	comment	Why do some physicists believe that scalable quantum computing is possible? @zephyr I'm not here just to argue. I'm trying to get to the truth via the Socratic Method. My evidence is the fact that scalable quantum computing requires control of an exponential amount of information. From this, I would expect an exponential amount of errors to correct.
