I think we should close all hospitals. Those stupid doctors can't cure all diseases therefore medicine is complete useless.

- cool-RR 17y agoI don't think your analogy is valid: Knowing how to cure all diseases would be a very high goal that stands above what doctors accomplished up to the present time. The challenge that I gave is below what physicists "know" today. When a physicist studies Qunatum Mechanics, he knows that on the macroscopic scale, QM will behave like classical electromagnetism. The problem that I raise, is that physicists don't know classical electromagnetism well enough in the first place. They can't calculate motion of macroscopic objects. I don't think it's wise to try to study QM before they solved that challenge, the same way it won't be wise to start learning Special Relativity before you studied Newtonian Mechanics.
- schtog 17y agoFair enough, I stand corrected, I commented as I did because I interpreted it as a typical "science can't explain everything therefore it is useless" or "your theory isn't perfect therefore my theory must be correct" rant.
- pfedor 17y agoWhen a physicist studies Qunatum Mechanics, he knows that on the macroscopic scale, QM will behave like classical electromagnetism. Why do you say this? Quantum Mechanics in the classical limit does not become classical electrodynamics. How could it? QM is non-relativistic. Classical electrodynamics is relativistic. QM in the classical limit becomes classical (Newtonian) mechanics.
- cool-RR 17y agoI admit I haven't studied QM, but I believe that it's relativistic. Maybe you have confused General Relativity with Special Relativity? QM is incompatible with GR, but I think it's based on SR.
- pfedor 17y agoWell, it isn't, and no, I haven't confused General with Special Relativity, trust me on that :) Maybe you confused Quantum Mechanics with Quantum Field Theory?
