Non Euclidean Geometry and the Universe

Posted on November 28, 2004 by PlatoHagel

With Critical density ( Omega ), matter distinctions become apparent, when looking at the computerized model of Andrey Kravtsov. Georg Friedrich Bernhard Riemann 1826 – 1866 Riemannian Geometry, also known as elliptical geometry, is the geometry of the surface of … 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 →

Is Line , Hook and Sinker, Dimensionally Leading to Soul Food?

Posted on November 21, 2004 by PlatoHagel

Oskar Klein (left) proposed in the 1920s that hidden spatial dimensions might influence observed physics. He poses with physicists George Uhlenbeck (middle) and Samuel Goudsmit in 1926 at the University of Leiden, the Netherlands. AIP Emilio Segrè Visual Archives I … 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 →

Holography and Dimensional Relevance

Posted on November 6, 2004 by PlatoHagel

Holography encodes the information in a region of space onto a surface one dimension lower. It sees to be the property of gravity, as is shown by the fact that the area of th event horizon measures the number of … Continue reading →

Physical Reality as a Four Dimensional Existence

Posted on November 4, 2004 by PlatoHagel

Since there exist in this four dimensional structure [space-time] no longer any sections which represent “now” objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical … Continue reading →

Quantum Harmonic Oscillator

Posted on November 3, 2004 by PlatoHagel

Let us see how these great physicists used harmonic oscillators to establish beachheads to new physics. Albert Einstein used harmonic oscillators to understand specific heats of solids and found that energy levels are quantized. This formed one of the key … Continue reading →

Compactifying a 3-D universe with two space dimensions and one time dimension.

Posted on November 3, 2004 by PlatoHagel

How do we learn to deal with these abstract spaces, but to have considered the following: (a) Compactifying a 3-D universe with two space dimensions and one time dimension. This is a simplification of the 5-D space­time considered by Theodor … Continue reading →

5th Dimensional Field Equations

Posted on November 1, 2004 by PlatoHagel

http://www.tech.port.ac.uk/staffweb/seahras/images/Kaluza.jpeg In 1919, Kaluza sent Albert Einstein a preprint — later published in 1921 — that considered the extension of general relativity to five dimensions. He assumed that the 5-dimensional field equations were simply the higher-dimensional version of the vacuum … Continue reading →
