To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

Recall that the solution of the initial-value problem \(y^\prime=ky\text{,}\) \(y(0)=A\text{,}\) is given by \(\ds y=Ae^{kx}\text{.}\) Solve the following problems ...

Back in 2007, physicists at the GSI heavy ion accelerator in Darmstadt, Germany, made a puzzling discovery. These guys were measuring the radioactive decay rates of praseodymium and promethium nuclei ...

In a random moment, all energy is lost. The unstable subject cannot help but decay, slowly but surely, letting go of particles to become stable. It loses itself to become balanced again. This is a ...
