Self-Organization of Matter

Posted on November 16, 2004 by PlatoHagel

Everyone knows that human societies organize themselves. But it is also true that nature organizes itself, and that the principles by which it does this is what modern science, and especially modern physics, is all about. The purpose of my … Continue reading →

Are Strings as Spacetime an Emergent Phenomena?

Posted on November 16, 2004 by PlatoHagel

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. Above Witten asks a legitmate question, and so does Gerard t’Hooft as shown in … Continue reading →

Longitudinal and Transverse Information about the Energy Deposition Pattern

Posted on November 15, 2004 by PlatoHagel

The calorimeter design for GLAST produces flashes of light that are used to determine how much energy is in each gamma-ray. A calorimeter (“calorie-meter”) is a device that measures the energy (heat: calor) of a particle when it is totally … Continue reading →

The Looking Glast

Posted on November 15, 2004 by PlatoHagel

To test the claim, Gninenko has proposed a new experiment at CERN. He and his colleagues would confine orthopositronium to a sensitive heat-measuring device, called a calorimeter. The device would be under a strict vacuum to isolate its contents from … Continue reading →

Universal Error Correction in Quantum Computation

Posted on November 15, 2004 by PlatoHagel

Physicists have succeeded in entangling five photons for the first time. Although four photons have been entangled before, five is the minimum number needed for universal error correction in quantum computation. Moreover, the same team has demonstrated a process called … Continue reading →

Do We Need a Radically New Spacetime/Quantum Worldview

Posted on November 15, 2004 by PlatoHagel

Whether such a “quantum computer” can realistically be built with a value of L that is large enough to be of practical use is a topic of much debate. However, the mere possibility has led to an explosive renaissance of … Continue reading →

2004 Promises to be an Exceptionally Exciting Year in General Relativity and Gravitation

Posted on November 14, 2004 by PlatoHagel

But you shouldn’t imagine the mood as one of breathless anticipation. At least for the physicists present, a better description would be something like “skeptical curiosity”. None of them seemed to believe that Hawking could suddenly shed new light on … Continue reading →

Mass Transfer to Blackhole

Posted on November 14, 2004 by PlatoHagel

This image is very strong in mind as I read Smolins discriptions of the thing?:) Consider any physical system, made of anything at all- let us call it, The Thing. We require only that The Thing can be enclosed within … Continue reading →

Fundamentals of Quantum Mechanics

Posted on November 13, 2004 by PlatoHagel

To me, Nature is a big jig-saw puzzle, and I see it as my task to try to fit pieces of it together. Click and cut the pieces you see here from the screen and see how they fit, or: … Continue reading →

Sound Waves in the CMB

Posted on November 11, 2004 by PlatoHagel

With the discovery of sound waves in the CMB, we have entered a new era of precision cosmology in which we can begin to talk with certainty about the origin of structure and the content of matter and energy in … Continue reading →
