what do you say we get together,

*Disclaimer: I am not a physicist. I wrote this when I was a freshman in high school and I have not verified it for accuracy, but I believe that one form of radioactive dating uses Uranium Isotopes 234 and 238. This is at least what my teacher told us in science class, which lead to me saying this ridiculously cheesy line to the girl sitting next to me.
