1. ### A layman a bit scared of the LHC (as always)

Why do you have the desire to be scared? Are you also a hypochondriac?
2. ### Lifetime of electrons and protons outside the nuclues.

How can the age of a proton be determined?
3. ### Strong force measurements

With the above equation (F=p*E/hbar) the electron "binding" force only 0.212 N .. But when multiplied by alpha^4/4 meters , the solution is equal to the mass-energy of a proton. Weird? Or is this pretty much nonsense?
4. ### Strong force measurements

Why wouldn't something like this work (to get a rough estimate)? If the energy required to separate the quarks within a proton is directly related to the mass-energy. F_binding_all_quarks = (p * E)/hbar The solution will be to the order of 100k newtons.

Thanks.
6. ### Strong force measurements

So, in other words, it is too much work to just post the answer here.
7. ### Strong force measurements

What would it be for a proton at rest (binding force in newtons)?
8. ### Strong force measurements

Can the strong force between quarks be measured in Newtons? Would the total binding energy of the 3 quarks in a proton be equal to it's mass-energy?
9. ### Velocity of atomic (hydrogen) electrons

Can you explain that equation, if you get a chance? Why does mv^2=27ev Thanks.
10. ### Strong force measurements

Thanks. new question. How does a strong magnetic field affect protons/neutrons?
11. ### Strong force measurements

Doesn't NMR involve high power magnets interacting with nucleons (is this the same as strong force)?
12. ### Strong force measurements

good question. nucleons
13. ### Fuction of a Neutron

do neutrons and protons contribute an equal amount of strong force?
14. ### Velocity of atomic (hydrogen) electrons

Hello, I've been wondering about the velocity of hydrogen electrons. I've read that 242,000 m/s was the correct velocity, however, I thought electrons would travel at c. How does one calculate this number? Thanks in advance.
15. ### Fuction of a Neutron

It seems strange that a neutron wouldn't have a function within an atom other than obtain mass, a neutral charge, and stick to protons. Do neutrons have more gravity than protons?
16. ### Strong force measurements

How is strong nuclear force measured?
17. ### Up and down quarks

How was the charge of up/down quarks determined?
18. ### Size of a neutron

Thanks. Astronuc, The "diameter" is more of a orbital boundary, correct?
19. ### Size of a neutron

If a proton and neutron have a mass of roughly 1.67e-27 kg . And a proton has a diameter of 1.65e-15 .. Is the diameter of a neutron the same?
