In this video, I discuss the experiments that led up to Chadwick’s identification of the neutron

## Heisenberg and his uncertainty principle

What is Heisenberg’s Uncertainty Principle? This strange concept is at the heart of quantum Physics. In this video, I explain, using simple terms, what it mean.

## Davisson and germer and proof of matter waves

De Broglie postulated that moving particles have a wavelength, but where was the proof? Enter Davisson and Germer who won the Nobel prize for Physics to show that electrons act like waves

## de Broglie and matter waves

In this video, we look at de Broglie and his strange suggestion that is light can have particle like properties, can matter have wavelike properties

## Bohr’s Atom

In this video, I discuss the postulates of Bohr’s atom, how it solves the problem of Rutherford’s model and how at the same time explains the lines is spectral analysis, including the Balmer lines

## History of Spectral lines and Balmer

Before discussing Bohr, it is helpful to look at the history of spectral analysis in the 1800’s, the Balmer lines and the Rydberg formula that describes them. This is then fully explained by Bohr in 1913

## Rutherford’s Gold Foil Experiment

In the first of a series of videos on the history of the atom, I discuss famous gold foil experiment that established a planetary model of the atom.
