Maggie was doing research for her Ph.D. in physics when a 12 mg sample of radioactive material decayed to 3 mg in 26 minutes. De

The general way to work this out is to solve the general expression for
the remaining quantity versus half-life, using logarithms. But that's not
necessary with these numbers.

Look at the numbers:

-- 3 mg is 1/4 of 12 mg.

-- 1/4 is the product of (1/2) x (1/2).

-- So the 3 mg is what's left of 12 mg after 2 half-lives.
The 26 minutes must be two half-lives.

-- The half-life of that substance is 26/2 = 13 minutes.
