apparently the person who did that was not very scientific, and:

Quote[/b] ]Fellow Massachusetts doctor Augustus P. Clarke took MacDougall to task for having failed to take into account the sudden rise in body temperature at death when the blood stops being air-cooled via its circulation through the lungs. Clarke posited that the sweating and moisture evaporation caused by this rise in body temperature would account both for the drop in the men's weight and the dogs' failure to register one. (Dogs cool themselves by panting, not sweating.) MacDougall rebutted that without circulation, no blood can be brought to the surface of the skin and thus no surface cooling occurs.
sometimes it's half an ounce, sometimes it's 3/4ths, sometimes it's 3/8ths
so I guess some people's soul is heavier than others'

Quote[/b] ]The weight of the soul he has determined to be from one-half ounce to nearly an ounce and a quarter.4
now how the heck did he get that?
[b said:
Quote[/b] ]What to make of all this? MacDougall's results were flawed because the methodology used to harvest them was suspect, the sample size far too small, and the ability to measure changes in weight imprecise. For this reason, credence should not be given to the idea his experiments proved something, let alone that they measured the weight of the soul as 21 grams. His postulations on this topic are a curiousity, but nothing more.
so SCIENTIFICALLY nothing was proven.
speaking of proving religious claims, I've seen more "proof" for other religions than for christianity.
My uncle and brother once got their "aura"'s picture taken. I don't know how the heck they do that, but you can see green/red/etc surounding a person. Sometimes you even see balls of light hovering on top of people's heads, etc.
there's also a guy who claims he reincarnated... he has one picture of the "previous" body he had, one of the body he took over BEFORE he took over (looked nothing like the "previous" body) and you can "see" that even though the first picture is not him, his "new" body changed to look more like the first body (did I just confuse the heck out of you? I know I'M confused! lol)
and that same guy... there's been pictures taken of him where he's meditating and he has white balls of light hovering around him and sort of light currents coming out of his assistant's hands.
How do I explain that? I don't have a clue but obviously I don't believe him because I don't have a religion.
anyway my point is that not only christianity has "proof".
(I've also seen pictures of honeycombs and fish scales with "alah" written on them, mosques that survived earthquakes, etc)
(now why the heck did I just say all that? I forgot... GASP! I need to do homework!)
