2Physics Quote:
"Perfect transparency has never been realized in natural transparent solid materials such as glass because of the impedance mismatch with free space or air. As a consequence, there generally exist unwanted reflected waves at the surface of a glass slab. It is well known that non-reflection only occurs at a particular incident angle for a specific polarization, which is known as the Brewster angle effect. Our question is: is it possible to extend the Brewster angle from a particular angle to a wide range of or all angles, so that there is no reflection for any incident angle."

Feynman on Commemorative Stamp


Richard P. Feynman, the late Nobel laureate and Caltech professor, is
widely regarded as one of the most influential physicists of the 20th
Century. Today United States Post Office has released a commemorative
stamp in honor of this great Physicist of 20th century.

Anyone interested in Modern Physics could never escape reading about
Feynman and his path-breaking works especially on Quantum
Electrodynamics and many other aspects of particle physics. The series
of lectures that he gave to Caltech undergraduates is celebrated as the
most comprehensive account of Modern Physics and if you have not yet
read his autobiography "Surely you are joking, Mr. Feynman" and a
sequel "What do you care what other people say", you must finish those
right now!

We cannot really describe Feynman, his work and his spectacular life in
two or three paragraphs of this posting. So, you may start with those books.Posted by Hello
