History
The history of invariance mechanics is difficult to pinpoint since many people have been working on it without realizing that they were working on invariance mechanics. Notable milestones include the 4-dimensional invariant found by Henri Poincaré in special relativity (1905), Yang–Mills gauge invariants theory. Roger Penrose and his spin-networks (1960's) influenced the subject. Cayley–Menger and their invariant based metric theory was an important milestone. Recently Baratin–Freidel (2006) have demonstrated the connection between invariance mechanics and loop quantum gravity.

Famous quotes containing the word history:
“... the history of the race, from infancy through its stages of barbarism, heathenism, civilization, and Christianity, is a process of suffering, as the lower principles of humanity are gradually subjected to the higher.”
—Catherine E. Beecher (1800–1878)
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”
—William James (1842–1910)
“Hence poetry is something more philosophic and of graver import than history, since its statements are rather of the nature of universals, whereas those of history are singulars.”
—Aristotle (384–322 B.C.)
