Dear Stu,

I'm really quite sorry in taking so very long to get
back to you--I thought I had sent a response but
apparently in between getting my wisdom teeth pulled
and my research it was never sent.  E^2=m^2c^4+p^2c^2
told Dirac in 1932 that for the same mass a there
existed to energies--positive and negative.  Hence the
concept of anti-matter, hitherto science fiction,
became a reality.  If you Google search (I used Yahoo,
but it should be about the same) anti-matter, one of
the first hits is a CERN website discussing
anti-matter (positrons in particular) which has an
excellent discussion of the history of anti-matter. 
Again I apologize for not responding sooner.  Thanks
for everything that you and Steve did.  We all has a
wonderful time at COSMOS.

Sincerely,
Mark Rodgers
