Differential equations, begone!

So if you had a sample of radioactive Harmytonium-126 and these conditions:

H(0)=300 moles
H(9)=150 moles
(where H(t)=how many moles of Harmytonium are left at time T)

Then you’d know that the rate was 8%?

Edit: Oh, never mind, the rule of 72 is for annual compounding/decaying. Apparently, for continuous decay/compounding, it’s the rule of 69. eh.

  1. Did we have Peanutbutterium? Now I can’t remember. I only remembered toastycrackerium because Sooyun used it has a word when we played hangman.
    Did we have anything to do with Mr. Squishyfish?
