Fotini Markopoulou-Kalamara Fotini Markopoulou-Kalamara, was born in Greece and is an Adjunct Professor in the physics department at the University of Waterloo, Canada. In her paper "The Internal Description of a Causal Set: What the Universe Looks Like from the Inside" Fotini Markopoulou-Kalamara instantiates some abstract terms from mathematical category theory to develop straightforward models of space-time. Markopoulou Kalamara found that by attaching light cones to the nodes of the networks, their evolution becomes finite and causal structure is preserved. www.mlahanas.de /Greeks/new/Kalamara.htm   (1703 words)

Spin network - Wikipedia, the free encyclopedia Spin networks were applied to the physics problem of quantum gravity by Carlo Rovelli, Lee Smolin, Fotini Markopoulou-Kalamara, and others to reformulate loop quantum gravity in the canonical approach. It was invented by Roger Penrose in 1971. en.wikipedia.org /wiki/Spin_network   (505 words)

United Press International - Science & Technology (no pub) - Astronomers look for space-time 'atoms' "We could describe the entire universe, find out what is the nature of time, what happened at the Big Bang, whether the life of the universe is infinite or finite," said Fotini Markopoulou Kalamara, a physicist with the Perimeter Institute for Theoretical Physics in Waterloo, Ont. Markopoulou Kalamara suggested that, like the conventional matter that comprises the Earth, the sun and the stars, space and time likewise are made of irreducible "atoms." If shown to be true, the finding would be compatible with both relativity and quantum theory, she said. Markopoulou Kalamara said because some gamma rays have less energy than others, they would have to travel different routes to reach an observer -- because a space-time continuum that is atomic would be lumpy in places. www.upi.com /view.cfm?StoryID=20030215-060322-2435r   (1172 words)

'Einstein`s Loops' At 31 years old, Fotini Markopoulou Kalamara is hailed as one of the world's most promising young physicists. Markopoulou Kalamara found that by attaching light cones to the nodes of the networks, their evolution becomes finite and causal structure is preserved. Markopoulou Kalamara explains, and that is why we see a smooth universe despite a quantised spacetime. mysite.wanadoo-members.co.uk /blobrana/features/quantrel.htm   (1132 words)

Wired 13.01: The BlackBerry Brain Trust Fotini Markopoulou Kalamara figured out how to introduce causality into loop quantum gravity theory. But Smolin and Markopoulou Kalamara are specialists in loop quantum gravity, which holds that space-time is a foamy network of intersecting loops known as spin networks. Much of the physics community is chasing superstring theory, the idea that the fundamental particles in the universe are actually multidimensional strings vibrating at different frequencies. www.wired.com /wired/archive/13.01/perimeter_pr.html   (2068 words)

Blogger: Email Post to a Friend one of the hotest up-and-coming LQG theorists is 31 years old, Fotini Markopoulou Kalamara. the most exciting part about this whole LQG thing is the way that fotini infuses the way that she looks at it with her upbringing as the daughter of two scultures. LQG, or loop quantum gravity is a new and exciting form of math and TOE (theory of everything) that challenges the realities posited by physicists who advocate superstring theory. www.blogger.com /email-post.g?blogID=3782780&postID=93840179   (227 words)

De Se Fotini Markopoulou-Kalamara It gives me a sense of déjà vu to chance upon Fotini Markopoulou-Kalamara now, having encountered an article about her research more than a year ago. While i am a popular science enthusiast and find fotini's work fascinating what captivates me is the exquisite mix of stunning beauty and sheer brilliance she possesses. Back then I thought what she was attempting to do was fascinating; today it is even more so, if only because I stand even more in awe of what she has already achieved. jeremychong.typepad.com /j/2004/03/fotini_markopou.html   (369 words)

Fotini MarkopoulouKalamara - Definition up Erdmond.Com In her interdisciplinary paper "The Internal Description of a Causal Set: What the Universe Looks Like from the Inside" Fotini Markopoulou-Kalamara instantiates some abstract terms from mathematical category_theory to develop straightforward models of space-time. The diagrams in Markopoulou's papers (including hand-drawn diagrams in one of the earlier versions of "The Internal Description of a Causal Set") are straightforward presentations of possible models of space-time. Her foundational work in quantum physics has been compared to Cantor's foundational work on the theory of the continuum (this may be considered ironic). www.erdmond.com /Fotini_Markopoulou-Kalamara.html   (379 words)

BLOG@STEFANGEENS.COM Fotini Markopoulou Kalamara has developed a framework for combining relativity and quantum theory that is much more elegant than string theory, because it does not presuppose space and matter but instead gives rise to space and matter, as we'd hoped all along a theory of everything would do. A Greek physicist decided to use some of her mother's cuisine tactics and may now have discovered the theory of everything. And it's based on the work of Roger Penrose, who is a bit of a colossal genius. www.stefangeens.com /000021.html   (1722 words)

The world's top loop quantum gravity websites Some radical approaches to spin foams include the work on causal sets by Fotini Markopoulou and Rafael Sorkin, among others. This approach is related to state-sum models of statistical mechanics and topological quantum field theory such as the Turaeev-Viro model of 3D quantum gravity, and also to the Regge calculus approach to calculate the Feynman path integral of General Relativity by discretizing spacetime. At the core of Loop Quantum Gravity is a framework for nonperturbative quantization of diffeomorphism-invariant gauge theories, which one might call Loop Quantization. dirs.org /wiki-article-tab.cfm/loop_quantum_gravity   (5682 words)
