John Bahcall and the Neutrinos

Posted on February 27, 2006 by PlatoHagel

John Bahcall1934–2005 What makes the sun shine? How does the sun produce the vast amount of energy necessary to support life on earth? These questions challenged scientists for a hundred and fifty years, beginning in the middle of the nineteenth … Continue reading →

Phase Transitions?

Posted on February 27, 2006 by PlatoHagel

G -> H -> … -> SU(3) x SU(2) x U(1) -> SU(3) x U(1) Here, each arrow represents a symmetry breaking phase transition where matter changes form and the groups – G, H, SU(3), etc. – represent the different … Continue reading →

Roots, and the Rings of History

Posted on February 26, 2006 by PlatoHagel

The jump from conventional field theories of point-like objects to a theory of one-dimensional objects has striking implications. The vibration spectrum of the string contains a massless spin-2 particle: the graviton. Its long wavelength interactions are described by Einstein’s theory … Continue reading →

More on Dual Nature of Blackhole

Posted on February 21, 2006 by PlatoHagel

In some theories, microscopic black holes may be produced in particle collisions that occur when very-high-energy cosmic rays hit particles in our atmosphere. These mini-black-holes would decay into ordinary particles in a tiny fraction of a second and would be … Continue reading →

Evidence for Extra Dimensions and IceCube

Posted on February 8, 2006 by PlatoHagel

…the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed. Albert Einstein Sometimes if we paid attention enough, the neurons seem to fire appropriately and … Continue reading →

Time

Posted on February 2, 2006 by PlatoHagel

You need a “Axion point” to derive symmetry breaking from equilibrium? Hmmmmm….. I’m thinking here. The idea is taking the first three minutes and moving it to the first three seconds and that’s where strings come in… I must warn … Continue reading →

Hyperspace

Posted on January 24, 2006 by PlatoHagel

Science is that human activity in which we aim to show towards nature that respect that in a democracy we endeavor to show towards each other.” There is no doubt my views are biased. For all the wrong reasons I … Continue reading →

Drawing a Venn diagram: Entanglement Issues

Posted on January 21, 2006 by PlatoHagel

Plectics, by Murray Gellman It is appropriate that plectics refers to entanglement or the lack thereof, since entanglement is a key feature of the way complexity arises out of simplicity, making our subject worth studying. The person above was kind … Continue reading →

KK Tower

Posted on January 5, 2006 by PlatoHagel

Like many people who devote their time to understanding the nature of the cosmo and the micro perspective of the world around us, these things have their own motivational packages which move to further rquired comprehensions. In that, one needs … Continue reading →
