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.) |

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

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.
