This video covers the very complex topic of quantum mechanics. This video covers the beginnings of this branch of science and why it came to be, and then goes on to explain the historical contributions scientists have made to this new field. Quantum mechanics is the study of physics at the nanoscale and came to dominance in the early 1900’s. At this scale, the concepts of classical physics becomes inaccurate, so quantum mechanics was developed to help explain these conundrums. When certain gases like argon or hydrogen were heated, it was noticed that instead of giving off a continuous spectrum of light, only finite lines of light were produced, known as spectral lines. This and many other observations were made that did not go along with what was predicted by classical mechanics which called for a new theory. The main promoter of this new theory was Niels Bohr, and he came up with the idea that energy comes in packets known as quanta and that electrons in an atom reside in certain specific energy levels of an atom that lead to these lines. The video goes on to describe other contribution of other scientists like Werner Heisenberg, Max Planck, Richard Feynman, and the most notable Albert Einstein. The experiments and conclusions these notable men came up with radically changed the world we live in and the video ended in saying that the beauty of this new theory was so nonsensical and unheard of that it removed the limit on imagination.
This video is incredibly creative and engaging. This is a complex topic but it has a lot of visual content to aide in your understanding of the topic. It shows pictorially a lot of the experiments these scientists carried out to help you make sense of it. It also shows what a lot of these scientists looked like and pictures of their work to make it more interesting. The narrator was engaging and there was a lot of interesting background music that kept your attention. The video was very methodical in the way it presented the information. It introduced the concepts and whose idea it was and related it to a lot of everyday phenomena you see and they used a lot of everyday materials like billiard balls and such to help explain these complex topics. Overall, this video was easy to understand because it kept the audience engaged with its movie-type format and its high visual and explanatory content.
