The 2,400-year search for the atom – Theresa Doud

View full lesson:

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud details the history of atomic theory.

  1. Ry Arm disse:

    Why is Schrodinger absent from this video? He is literally the most important person. This video talks for a few seconds about quantum theory but offers no information. Students are going to think that the Bohr model is how the atom looks, which is not true at all. I am so disappointed in this video. Students, PLEASE don't stop here! Look up the quantum model of the atom!
