In addition, any modification to the central equations of physics would have to give results that are only a slight correction to existing theories – just as Einstein's equations offer very similar answers to the approximations of Newton's that claims to unify and replace two theories that are accurate to 10 decimal places, but he cannot tell you whether or not his theory is accurate to any decimal places, then you can be pretty sure that he has not solved a physics problem. 2) Resolve the problem of observer-dependence in quantum theory . Given the level of knowledge of the cranks in this group, you probably wouldn't notice much difference. ( —Physicists Rodolfo Gambini and Jorge Pullin of University of the Republic in Montevideo, Uruguay, and Louisiana State University respectively, have applied the theory of Loop Quantum Gravity . Smolin identifies five challenges facing physics: 1) Combine general relativity and quantum theory into a single complete theory. Symmetry is a key ingredient in many mathematical, physical, and biological theories. Galois was the one responsible for first really understanding the significance of the concept of a group, and using it to get deep insights into the structure of the solutions of polynomial equations. A long-repeated example, of course, is the physical understanding that condensed matter physics provided via the renormalization group to elementary particle physics. An atomic physics experiment demonstrates a solution to an eighty-year-old quantum conundrum by mimicking in an atom the astronomical problem of a satellite moving in a sun-earth system. Livio gives the standard party-line about string theory, but he does do one very interesting thing. Yet if you ask physics-friendly laymen what cutting-edge physics is about, the answers will typically span the Big Bang, Higgs boson, black holes, dark matter, string theory and even time-travel. Gallagher (University of Virginia) have beautifully demonstrated in the laboratory a solution to this problem of the spreading atomic electron wave packet using a trick that was discovered in astronomy long before the problem arose in quantum theory [3]. Nuclear Physics / Theoretical physics Today's industry standard for reactor core calculations is based in a two-step procedure where full of piecewise assembly homogenizations based on lattice fine-group two-dimensional (2D) transport calculations are used to compile a Each one of the sub domain matrices is obtained from the solution of GXN transport source problems for a fixed lambda value and boundary incoming flux given by each surface mode and each macrogroup. This version is accelerating towards a de Sitter solution which gives permanent expansion, there will be no big crunch this time to restart another bang. See string theory miss the boat and then get "rescued" by a new formulation, a new set of constraints and, what the heck, an extra dimension or two in order to explain a new observation or to wish a couple of hundred trillion solutions into the cornfield. There will be scant mention if any of say spectroscopy, optics, . The latter part of the book deals with the important role of symmetry in modern theoretical physics, and this is a topic treated in many other places in more detail.
