comment Photoelectric effect with protons
The nuclear binding energy per nucleon is on the order of a couple of MeVs, while the electron binding energy for the outermost electron is in the tens of eVs. I don't know why you're mentioning the inverse of the fine structure constant here!

comment How do we know that C14 decay is exponential and not linear?
Galileo would be proud! @Ruud: So 2 separate boxes with 500M atoms would decay entirely in 5700y, but if you put them together half would remain. That seems a bit strange, to say the least...

comment The philosophy behind the mathematics of quantum mechanics
@recipriversexclusion: I have a CS background, and those lectures really made it click what quantum computing was about, in terms of computation (as opposed to the physics aspect). I hope it's the same for people coming from physics. Glad you liked them, in any case!

comment Addition of different physical quantities
@Saeed, if you do that, then presumably also 4 oranges + 3 apples = 7 fruits, from which you can derive 1 orange = 1 apple. You might as well call them fruits straight away!

revised Outcomes of earth slowing down spinning on its own axis
Misinterpreted the difference between mean solar day and 86400 s as being due to tidal braking.

Whoops, should have read a bit more. Thank you for the correction, I'll edit it in.

revised Newton's cradle
Fixed spelling (verticle!) and punctuation. Currrently proofreading a PhD thesis so I'm hypersensitive :)

comment Light travels a straight line write down the principle in which this is manitested
It's also nice to show what you've tried, what did or didn't work with your approach, and a 'please' at the end also help in posing a question.

What about a combination of 3 up quarks?
