Practice Problem: Radioactive Half-Life
All radioactive nuclei have a particular half-life, or the time it takes for their concentration to be cut in half. Given the half-life of one such nuclide, can you find the decay constant, and the fraction of nuclei left over after a...

Is Fine-Tuning in Physics Evidence of a Creator? A Scientific Viewpoint
Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a...

Why Does Everything Decay Into Lead
If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...
