Post:
In the I cube experiments, the light through the cube starts bright and
then dims after a brief time interval. Is this real or an electronic
artifact?

Thanks,

Sam

Folks,

I have dreamed up some questions for our Question of the Week site and
would like to use you all as a filter, to see if (a) anyone understands
this, (b) anyone finds it interesting, and (c) anyone finds errors.

Click on:

http://www.physics.umd.edu/lecdem/outreach/QOTW/new/new.htm

and go to Questions and Answers #290, #291, and #292.

Admittedly, this may be a bit obscure, but I think they are interesting.

We came into possession of the little cubes, apparently originating from

Professor Costas Papaliolios (now deceased) of Harvard University
through
a somewhat circuitous route, back in about 1975, along with a one-page
list of the matrices that each cube symbolizes. I believe that I have
finally figured out what is in the cubes, and how they work.

Thanks for your help.

Dick
