The probability of the OP getting laid with an opening line like that.

There's obviously no nuclear physicists on ATOT tonight. It's a barn, you morons!

Unit used in nuclear physics to indicate probability of a reaction between nuclear particles and atomic nuclei or even other nuclear particles. The dimension of the Barn is cross sectional area and 1 Barn is equal to 10-28 m². The ?physical cross section area? of the nucleus of an atom is approximately 1 Barn but depending on the reaction involved the actual ?reaction cross section area? can vary over many decades of Barns in size and are very dependent on particle energy.

I was just gonna post a barn, but meh.

Actually a barn is fairly large in particle physics terms, hence the name (couldn't hit the broadside of a barn).

What's a mole again? 10^26? Man, it's only been a year since chemistry and I've already forgotten stuff.

6.02 x 10^23

There's actually a thread about this tonight. My humor was not recognized :p

Oh wow, I slaughtered that. Didn't even get the right exponent. Chemistry was a shitload of work but man was it fun. Can't wait for AP Physics. Taking a break from science this year then gonna hit it hard with a baseball bat next year.

Quickly! What is so important about the number
