"Principle of Relativity" was coined by Poincare in 1904

Glad that Farsight provided us a link for the translated version of Einstein's article on Special Relativity.

I noticed that the term "Principle of Relativity" in the 5th line of the 2nd paragraph was actually coined by Poincare at least in 1904.
http://www.annales.org/archives/x/Relativity.doc .
It unveils the early achievements of Poincare were studied by Einstein yet never mentioned by Einstein in his 1905 paper. "according to his friends Maurice Solovine and Carl Seelig, Einstein read Poincaré’s book La Science et l’Hypothèse (no absolute time, no absolute space, no ether…) during the years 1902-1904. This book was discussed at their lecture circle “Olympia Academy” over several weeks (Ref. 8, pages 129 and 139 ; ref. 9 page VIII and ref. 17 page 30)."
And also some historical background why Poincare was not even supported by physicists (even those of France). His papers were not accepted by physics journals. Only published by infamous mathematics journal. They were written in France unreadable to most physicists. And the health of Poincare became bad (cancer) in 1909 before his death 1912.

What Poincare needed was the physical interpretation to which was supplied by Einstein when he stated that the principle of relativity implies that all physical laws does not change for any observer in any inertial frame of reference or simply means that there is no preferred frame of reference. Poincare was more of a mathematician than of a physicist. Einstein was more of a physicist than a mathematician.

Einstein was more of a physicist than a mathematician.

Unfortunately, Special Relativity became useful/popular/powerful only after a mathematician Minkowski (the teacher of Einstein) converted the physical reality of space and time into mathematical spacetime.

It is long overdued for physicists to separate again time and space into distinct linked loops of quantum space-time. One loop represents time the other represent 1D space.

Yes, wikipedia says that "While a Euclidean space has only spacelike dimensions, a Minkowski space has also one timelike dimension. Therefore the symmetry group of a Euclidean space is the Euclidean group and for a Minkowski space it is the Poincaré group." http://en.wikipedia.org/wiki/Minkowski_space

Modern Physics builds on Minkowski space.
It is ironic that Minkowski space is a Poincare group (as of the symmetry group).
Wikipedia also says that "In physics and mathematics, the Poincaré group, named after Henri Poincaré, is the group of isometries of Minkowski spacetime." http://en.wikipedia.org/wiki/Poincar%C3%A9_group

As one of the seven Millennium Problems, the first person to prove or disprove the Poincare conjecture will receive $1M dollars from the Clay Mathematical Institute.

The Poincaré conjecture has been proven (a couple of years ago, I think). The guy who proved it declined the Fields medal, and will most probably decline the $1m (if he hasn't already).

I was wondering if this conjecture could help me realize cold fusion?
