  1. Hace 2 días · The Fermi paradox is a conflict between the argument that scale and probability seem to favor intelligent life being common in the universe, and the total lack of evidence of intelligent life having ever arisen anywhere other than on Earth.

  2. Hace 1 día · A complementary cusp catastrophe theory approach to the problem is also introduced. Difficulties associated with the DFT-based approach to the study of the pJTE are discussed and changes in the electronic structure are explored using the Quantum Theory of Atoms in Molecules.

  3. Hace 4 días · The model was developed by extending the stochastic cusp model, as proposed by Thom in the 1970s under the mathematical-statistical model based on the catastrophe theory. The CUSPRA approach can identify the presence of a regime shift due to two synergistic pressures and determine how far the system is from the change.

  4. Hace 1 día · Transition state theory fails to capture the reaction kinetics and explain the obsd. stereochem. distributions. Ab initio steered mol. dynamics reveals unique non-equil. dynamic effects: energy transduction from the first cycloreversion substantially accelerates the second cycloreversion, and bifurcation on the force-modified potential energy surface leads to the product distributions.

  5. Hace 3 días · Adherents to the idea, following a theory first proposed by Munro Edmonson, alleged that the Maya based their calendar on observations of the Great Rift or Dark Rift, a band of dark dust clouds in the Milky Way, which, according to some scholars, the Maya called the Xibalba be or "Black Road".

  6. Hace 1 día · The current standard model of particle physics is based on quantum field theory. QFT treats particles as excited states (also called quantum levels) of their underlying quantum fields, which are more fundamental than the particles.

  7. Hace 1 día · Lukács. Catastrophe. Progress. In Memory of Agnes Heller (1929–2019) When utopian and science fiction studies explore inter-war German Marxism, their attentions are invariably concentrated on Ernst Bloch, who is typically seen as a utopian exception to the anti-utopian Marxist rule. But Bloch was by no means the only “utopian” to move in ...
