Clips from "The Mechanical Universe" on relativistic momentum. (This requires that you establish a free account, but it is well worthwhile -- I'll be posting quite a number of clips from this series.) Go to episode 44 (Mass, Momentum, Energy), then scroll to the desired time. If desired, right-click the movie and choose "Zoom" to make the movie larger. DO NOT waste your time watching the whole episode -- there is an unusual amount of fluff in this particular one.

Episode 44
6:15-7:55 Review of classical momentum
9:20-14:50 Relativistic mass and momentum
(The z-axis on the spacetime diagram is time, but don't worry too much about it.)

Episode 44
15:30-17:20 and 18:30-20:35 Increased mass interpretation
18:30-20:35 Relativistic energy

Biography of Max Planck
"I knew the formula that reproduces the energy distribution in the normal spectrum; a theoretical interpretation had to be found at any cost, no matter how high."

Biography of Louis de Broglie
"You had the boldness to assert, without the support of any known fact, that matter had not only a corpuscular nature, but also a wave nature. Experiment came later and established the correctness of your view." -- C W Oseen, Chairman of the Nobel Committee for Physics

Plots of orbitals for hydrogenic atoms

 

 

Researchers at the IBM Almaden Laboratory used a scanning tunneling microsope to position 48 individual Fe atoms in a circular corral on a Cu surface. The waves seen eminating from the center are due to quantum mechanical wavefunctions of the surface electrons forced into circular states by the arrangement of the Fe atoms.
