Mass Spectrometry
In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass...

Atomic Nucleus
In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

Who decides how long a second is? | John Kitching
In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how...
