Radioactive decay is a spontaneous and random process. A block of radioactive material will contain many trillions of nuclei and not all nuclei are likely to decay at the same time so it is impossible ...

Sara and Beca learn about constructing a half-life graph with the help of both Ada the science app and an early version of Ada. After finding an old phone in her home, Sara shows Beca how the old ...

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...

The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there's nothing that it obviously ...

Physicists in France have measured the longest ever radioactive half-life - over twenty billion billion years - in a naturally occurring element that decays by emitting alpha-particles. Nőel Coron and ...
