radioactive decay

Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns.

Helium is a byproduct of natural gas extraction, and it also occurs naturally from radioactive decay in the Earth’s crust.

Quantum theory governs everything from semiconductors which are ubiquitous in computer chips, to lasers, to superconductivity to radioactive decay.

It forms through the radioactive decay of uranium and thorium deep in the crust and eventually seeps out and escapes into space.

The atom-by-atom analysis enabled researchers to count how many atoms in the zircon crystals have undergone radioactive decay.
