Martin Perl, a Nobel Prize-winning physicist from Stanford University who discovered a subatomic particle known as the tau lepton, has died at age 87.
The university said the retired professor, one of two American scientists who shared the Nobel Prize for physics in 1995, died at Stanford Hospital on Tuesday.
He was recognized for work he did during the 1970s at the Stanford Linear Accelerator Center, a federally funded laboratory where scientists investigate the tiniest pieces of nature.
At the time Perl discovered the tau lepton, many physicists doubted the particle — that would turn out to be a heavyweight cousin of the electron — existed. He eventually proved them wrong using a new kind of accelerator in which electrons and positrons course in opposite directions and collide.

another way to look at it is to assume the normal electron interacts with the gravity field (and some tachyons)
to "hide" from the overall universe-permeating gravity field its "stolen extra mass".
seems it cannot hide the "weight loan" for long but maybe if a technological setup is found to let the heavy-weight electron
repay its loan without getting annihilated in the process, then this might very well be the starting point for a
"Alcubierre drive"?
