Quantum Gravity 361.2: Superstring and M Theory Dualities Related to "Duality" in P(A-->B) - P(B-->A)

From Osher Doctorow From the viewpoint of the last few posts, we can obtain a completely different interpretation of Superstring and M Theory and even Supersymmetry relating to these, in terms of the Dualities there. The main Dualities, T-duality and S-duality, relate theories with circular radius r and those with circular radius 1/r (T-duality) or... more »

	A Challenge to mathematical physicists
	In the next sentence, answer the first two questions and then answer, if you can, the third and most significant one. In Einstein's 1905 equation tau = a(t - vx'/{c^2 - v^2}), where did the "a" come from and what does it signify; and IF it IS "a function phi{v) at present unknown" WHAT is its value if, as he later... more » By glird - 12:05pm - 4 new of 4 messages

	A constant speed of light in all reference frames? Surely you can't be serious.
	...<< If physicists understood the equations in segment 3 of Einstein's 1905 STR paper, they would KNOW the following things: 1. Einstein never did accurately derive the LTE. 2. He neither understood his own OR Poincare's equations. 3. Neither has any physicist then or now. (If they did, they would... more » By glird - 11:58am - 2 new of 2 messages

	"Where Is The Kinetic Energy of a Bullet Stored?"
	"Where Is The Kinetic Energy of a Bullet Stored?" (See also our sister website reticsessays.com) When a bullet is fired, an explosive charge imparts kinetic energy to the bullet. That kinetic energy travels with the bullet and is transferred to the target when the bullet strikes. The question to be answered is where... more » By Tenrac - 10:49am - 2 new of 2 messages

	EINSTEIN EXERCISING HIMSELF IN CRIMESTOP
	[link] George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are... more » By Pentcho Valev - 8:45am - 1 new of 1 message

	THIS MESSAGE TRAVELED LIGHT YEARS TO GET HERE . . .

	Quantum Gravity 361.1: What is the Actual Reason for Orbits, Energy Levels, Tori (in Integrable Systems) according to Probable Causation/Influence?
	From Osher Doctorow The equations: 1) P(A-->B) - P(B-->A) = P(B) - P(A) = k 2) P ' (A-->B) - P ' (B-->A) = 2(P(B) - P(A)) = 2k for k real constant, define orbits or bands/tori of orbits as all sets B or pairs of sets A, B such that P(B) = P(A) + k for a particular constant k, or alternatively all set pairs A, B such that P(A) = P(B)... more » By OsherD - 2:43am - 1 new of 1 message

	The electron has substructure that radiates.
	The sub-photons and sub-neutrinos that are given off by the much finer-structured sub-matter which constitutes the electron are not only 10^27 times smaller than regular photons, they also propagate faster. When electrons are accelerated in a circle, these emanations are given off more in the direction of the magnetic field.... more » By john - 2:40am - 8 new of 8 messages

Four new papers discuss the relationship between solar activity and climate

Four new papers discuss the relationship between solar activity and climate: one by Judith Lean (2010) in WIREs Climate Change, a GRL paper by Calogovic et al. (2010), Kulmala et al. (2010), and an on-line preprint by Feulner and Rahmstorf (2010). They all look at different aspects of how changes in solar activity may influence our climate.... more »
