4. Oh yeah, could anyone tell me how they did 14 b ii? I just found out the difference in mass and calculated that as MeV. Although wouldn't the "Np" have some energy too?
5. btw did everyone get 5600 as the temperature of the sun?
6. How much are you all getting?

I just found the mass difference.
why?
9. For the lung question, I used 1.3 x 10^-4 instead of 1.25 x 10^-4. Would I lose marks for this?

what did people put for question 10
I put B. The force is inversely proportional to the square of their distance, not proportional.
12. ...I'm just not going to look at it. We've got such a horribly long wait until our results. I'd rather not know.

Weird I know.

lol, i read somewhere that this scientist got a hissy fit over mariah carey's album E=MC2 and the he was all like "you're misguiding people blah blah blah..."
i dont know what happened after that
Scientists getting all wound up over things like that I imagine does far more damage to the public perception of science and the amount of people taking it up than perhaps the odd wrong fact here and there does... I mean my god... a bit of scientific information makes its way into popular culture! That should be celebrated and encouraged even if the facts are a little dodgy... 13.7 billion light years just doesn't rhyme very well after all! It's not supposed to be a replacement for actual scientific fact....
