Catch a Wave From Space

Posted on December 17, 2004 by PlatoHagel

Imagine the journey it took for us to have come to the developement of the methods to discern the nature of the Universe, and what Einstein has done for us in terms of General Relativity. A statement, about Gravity. Imagine … Continue reading →

Quantum Geometry

Posted on December 9, 2004 by PlatoHagel

Mathematics is not the rigid and rigidity-producing schema that the layman thinks it is; rather, in it we find ourselves at that meeting point of constraint and freedom that is the very essence of human nature. – Hermann Weyl I … Continue reading →

What Do We Mean When We Say "Continuum"?

Posted on December 7, 2004 by PlatoHagel

Here’s a description Albert Einstein gave on p. 83 of his Relativity: The Special and the General Theory: The surface of a marble table is spread out in front of me. I can get from any one point on this … Continue reading →

Quantum Harmonic Oscillators

Posted on December 5, 2004 by PlatoHagel

If the basis of this thinking has not emerged out of GR then what value could we have assigned zero point vibration? If the scalable features of GR could not have followed some geometrical thinking, then the world that we … 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 →

Quantum Geometricization: The Struggle

Posted on November 29, 2004 by PlatoHagel

If Lorentz symmetry is broken by some mechanism originating at the Planck scale, is there any hope of detecting such an effect? Surprisingly, the answer is yes. Over the past decade Kostelecky and co-workers have been exploring how a violation … Continue reading →

No Royal Road to Geometry?

Posted on November 26, 2004 by PlatoHagel

All those who have written histories bring to this point their account of the development of this science. Not long after these men came Euclid, who brought together the Elements, systematizing many of the theorems of Eudoxus, perfecting many of … Continue reading →

The Man Who Knew Infinity:

Posted on November 24, 2004 by PlatoHagel

A Life of the Genius Ramanujanby Robert Kanigel Srinivas Ramanujan (1887-1920)In the past few decades, we have witnessed how Ramanujan’s contributions have made such a profound impact on various branches of mathematics. The book, “The man who knew infinity”, by … Continue reading →

Mathematicians and Physicists Do is Perhaps Like Sculpture

Posted on November 23, 2004 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.” Smolin then goes on to write something interesting here. Many would have interpreted the … Continue reading →

Quantum Gravity

Posted on November 22, 2004 by PlatoHagel

Here is one of two methods that help explain. The next post will follow tomorrow if I have time. The complexity of the pictures involved is linked down below in Fig 15-17. This will give some generalizations that I had … Continue reading →
