Put that chunk of uranium on a scale and you have a 700 milion year calendar
GOD DAMNIT! Who touched my Uranium-235?? I left it RIGHT HERE where this lead is.
Somebody touch-a my U235
Whose responsible this?!?!
Who measures uranium in pounds? I feel like if you’re not using metric you probably shouldn’t be handling uranium.
So I ran the numbers. U-235 decays into Pb-207, which means about 12% of its mass is radiated away in alpha decay. Which sounds like a fuckton.
Also, it’ll mean that that chunk of lead will be a touch heavier, at 13.2 lbs
The Maths:
U-235 decays into Pb-207. To three significant digits, 207/235 = 0.881, equivalent to 88.1%, meaning 11.9% is radiated away.
88.1% of 15 lbs = 13.2 lbs.u-235 has a half life of 704 million years. only half of it would have decayed.

Reminds me of my ingot of invar. Every few years I try to think of something to do with it, but still haven’t come up with anything.
What’s invar?

In short, it is an alloy that experiences almost zero thermal expansion or contraction.
And I thought it was some deez nuts joke that I wasn’t aware of
No snoot, there’d be crabs!!
This meme is false.
So a chunk of lead today could have been pre-cambrian uranium?
Awww greyhound snoot 😍
