Blaise Pascal

Posted on May 25, 2005 by PlatoHagel

Blaise Pascal (June 19, 1623 – August 19, 1662) Born in Clermont-Ferrand (France), the young Pascal was introduced to mathematics and physics by his father. So precocious was his talent in these disciplines that he published his innovative Essai pour … Continue reading →

The Holographical Mapping of the Standard Model onto the Blackhole Horizon

Posted on April 26, 2005 by PlatoHagel

New paper that came out yesterday written by Gerard ‘t Hooft Interactions between outgoing Hawking particles and ingoing matter are determined by gravitational forces and Standard Model interactions. In particular the gravitational interactions are responsible for the unitarity of the … Continue reading →

Emergence= Phase Transitions of Symmetry?

Posted on March 22, 2005 by PlatoHagel

Witten said: One thing I can tell you, though, is that most string theorist’s suspect that spacetime is a emergent Phenomena in the language of condensed matter physics. Part of the difficulty was realizing that the end result of a … Continue reading →

The Arrow of Time

Posted on February 15, 2005 by PlatoHagel

Rudolf Julius Emanuel Clausius There is but one kind of entropy change. Entropy change is due to energy dispersal to, from, or within a system (as a function of temperature.), measured by microstate change: S = kB ln [microstates final … Continue reading →

Quantum Microstates: Gas Molecules in the Presence of a Gravitational Field

Posted on December 4, 2004 by PlatoHagel

Andy Strominger: This was a field theory that lived on a circle, which means it has one spatial dimension and one time dimension. We derived the fact that the quantum states of the black hole could be represented as the … Continue reading →

Fool’s Gold

Posted on November 20, 2004 by PlatoHagel

Ludwig Boltzmann (1844-1906) In 1877 Boltzmann used statistical ideas to gain valuable insight into the meaning of entropy. He realized that entropy could be thought of as a measure of disorder, and that the second law of thermodynamics expressed the … Continue reading →

The Holographical Principle

Posted on November 11, 2004 by PlatoHagel

I must add a very important note. It is still hard for me to believe that Lee Smolin wrote something that could imply that *he* was the author of the conjecture. Lee Smolin has nothing to do with the discovery … Continue reading →

Information in the Holographic Universe: A Holographic Spacetime

Posted on November 9, 2004 by PlatoHagel

by Jacob D. Bekenstein TWO UNIVERSES of different dimension and obeying disparate physical laws are rendered completely equivalent by the holographic principle. Theorists have demonstrated this principle mathematically for a specific type of five-dimensional spacetime (“anti–de Sitter”) and its four-dimensional … Continue reading →

Plato’s Cave and Heisenberg, 21st Century with Witten

Posted on November 2, 2004 by PlatoHagel

Breaking Symmetry Here I sit in Brane world and the idea of “Pants” reaching different dimenisons seems intrigueing to me. Far beyond the views that one see from the light shining, from the open mouth of the cave, some far … Continue reading →
