- T1 E9 - Quarks, Color, and the Strong Force2 de marzo de 201732 minExplore the force that helps hold the atomic nucleus together, called the strong force. Chart the discovery of this mysterious mechanism - which only works at extremely short range - and see how it led to concepts such as quarks, gluons, and the color force, which is responsible for the strong interaction.Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E10 - Standard Model Triumphs and Challenges2 de marzo de 201729 minBring together all the concepts studied so far to gauge how close physicists are to a theory of everything. Focus on the shortcomings of the standard model. Then zero in on two burning questions: Why is the mass of the Higgs boson so low, and why does matter predominate over antimatter?Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E11 - How Neutrino Identity Oscillates2 de marzo de 201731 minTransition to a new perspective as Professor Lincoln spotlights speculative ideas that may contribute to a theory of everything. In this lecture, explore the mysteries of neutrinos, which are extraordinarily hard to detect yet hold intriguing clues about the possible unity of fundamental forces.Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E12 - Conservation Laws and Symmetry: Emmy Noether2 de marzo de 201731 minConsider why mathematics is such an effective tool for describing nature. Then focus on mathematician Emmy Noether's remarkable insight that links symmetries in the equations of a physical system to conservation laws, such as the conservation of energy and conservation of momentum.Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E13 - Theoretical Symmetries and Mathematics2 de marzo de 201731 minThe first inklings of a successful theory of everything will probably arise from symmetries and group theory. Prepare for this epochal moment by digging into these important mathematical ideas. Also, learn to approach proposed theories of everything with fascination, tinged with healthy skepticism.Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E14 - Balancing Force and Matter: Supersymmetry2 de marzo de 201734 minOne of the most attractive ideas for physicists searching for a theory of everything is supersymmetry, which treats force- and matter-carrying particles as interchangeable. Explore major problems that supersymmetry solves and the shortcomings that convince some scientists that perhaps some other ideas must also be considered.Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E15 - Why Quarks and Leptons?2 de marzo de 201731 minThe fundamental building blocks of matter are thought to be quarks (which interact by the strong force) and leptons (which interact by the electromagnetic and weak forces). But could there be a deeper level? Explore the theory of preons, which may be even more fundamental than quarks and leptons.Periodo de prueba gratis de The Great Courses Signature Collection o compra
- T1 E16 - Newton's Gravity Unifies Earth and Sky2 de marzo de 201729 minGravity is by far the weakest of the fundamental forces. Learn how Newton achieved the first major unification in physics by showing that terrestrial and celestial gravity are the same. He also tacitly equated inertial mass and gravitational mass, leading to the startling theory 250 years later.Periodo de prueba gratis de The Great Courses Signature Collection o compra
