Ibuprofen and Naproxen (Advil/Motrin/Aleve)
Ibuprofen is another one of the most commonly prescribed drugs in the world, and is also another NSAID. It was developed in the 1960s, so let's get a closer look at ibuprofen and a similar drug named naproxen, so that we can compare...

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...

Understanding Radioactive Half-Life
This video explains the concept of half-life in relation to radioactive decay of isotopes. It discusses the two ways in which half-life can be defined and how the random nature of radioactive decay gives rise to the idea of half-life....

Half-Life _ GCSE Physics
When a radioactive atom goes through alpha or beta decay, the atom itself changes into a different element. For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. It’s impossible to predict when an individual atom...

Radiometric Dating: Carbon-14 and Uranium-238
When you read about the ages of certain ancient artifacts, or even the age of the earth itself, how do we know such numbers? How can we know that a fossil is precisely 250 million years old? The key technique here is radiometric dating....
