The first liquefaction of helium in 1908 by Dutch experimental physicist Heike Kamerlingh Onnes was revolutionary. For the first time, scientists could push the boundaries of extremely low temperatures and see what happens to materials. 3 years after that feat, Onnes wanted to test something new: what happens to a metals electrical resistance as you reach those critical temperatures? 3 theories existed before Onnes tackled the problem, one by Lord Kelvin, one by James Dewar, and one by Augustus Matthiessen. However, when it came time to experiment, he collected data that matched none of the 3 existing theories. His discovery shocked the world of physics and introduced an entirely new concept to the community.

The weights of atoms and molecules are quite precise today, but has quite a long and complicated history. This video dives into the very beginning of that history, right when modern atomic theory was beginning to surface. John Dalton is the inventor of relative atomic weight, and his ideas were ins…
Absolute zero is the theoretical limit to how cold temperature can reach. The quest to calculate the value of it started in the 1700s, but wasn't accurately done so until the mid 1800s by British physicist William Thomson.
For over two centuries, Newton’s law of gravity accurately predicted the motions of all the planets in the solar system. But that all changed in 1859, when French astronomer Urbain Le Verrier discovered a strange anomaly regarding mercury’s orbit. This led to a problem in Newton's reality that didn…
After the discovery of beta radiation by Ernest Rutherford in 1898 and the formulation of the mass-equivalency relation by Einstein in 1905, scientists realized that beta radiation was behaving in an odd way. The expected kinetic energy of the beta particles was less than expected and spread out ov…
