Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show tries to explain why quantum mechanics has to be the way it is, due to a new definition of the calculus of 4D events in spacetime. Pictures are provided.
This is a talk I will be presenting at the 2007 April APS Meeting in Jacksonville, Florida. My GEM (gravity and EM) proposal is the spot between Newton's scalar gravity theory and Einstein's rank 2 field equations.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show is one of six talks given to a very small audience at MIT during the Independent Activities Period (IAP) titled "Unifying Gravity and EM by Analogies to EM." The topic covered are: 1. Must Do Physics, 2. Tensors, 3. Units.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show discusses two original artworks I produced inspired by lessons from physics: "The Speed of Light According to Rene Magritte" and "Groups of Coherent Photons Behave Like Waves and Particles".
On October 21, 2006, Doug Sweetser and Darra Sue Garrison got married by Rev. Elea Kemler in Groton, MA at the First Unitarian Church. The Winiker Swing Orchestra provided the Tunes for our 100 funky friends. A great time was had by all.
This is the talk I will present to the 8th International Conference on Clifford Algebras in Campinas, Brazil. The new two limit quaternion derivative definition has a real directional derivative for classical physics, and the norm of a derivative for quantum mechanics.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This is two of six talks given to a very small audience at MIT during the Independent Activities Period (IAP). The topic covered is Lagrange densities.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This is the fifth of six talks given to a very small audience at MIT during the Independent Activities Period (IAP). The topics covered are a physically relevant solution to the field equations, and forces.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This is fourth of six talks given to a very small audience at MIT during the Independent Activities Period (IAP). The topics covered are quantization and the standard model.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show explains Doug's approach to the biggest topic outside of physics there is, God. A brief definition of God will be presented that has been useful to Doug.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show touches three important puzzles: how to unify gravity and light, how to quantize such a proposal, and a new way to explain how galaxies rotate.
n 1915, Hilbert wrote the action used for gravity. As an amateur, I have worked on an alternative that unifies gravity and EM. The two actions will be contrasted because they make different predictions for light bending around the Sun at second order PPN accuracy, and for the polarization of quadrapole moment gravity waves.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. In this show Doug does not discuss physics at all, only Swing Dancing, a social activity he still enjoys.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. A talk at an American Physical Society is presented, along with talk about giving such talks.
Part of the Stand-Up Physicist series, half hour chats by Doug Sweetser about his theoretical physics research. This show talks all about Einstein, his musical creativity, his hope for a unified field theory, and special relativity. My own efforts and artwork are weaved into the stories told.
Adding one quaternion over and over to another quaternion generates what physicists call an inertial observer. Amazing that the simplest step in math creates something at the foundation of special relativity
The symmetries of the standard model are here: U(1), SU(2) and SU(3) as quaternion animations (time + 3D). By using spheres of different sizes as a function of local location on a manifold, the work of Diff(M) is on display
Gamma matrices are used in relativistic quantum field theory calculations. De Leo Nad researchers in Mexico (J. Lopex-Bonilla, L. Rosales-Roldan, and A. Xuniga-Segundo) have noticed that quaternion triple products can do the same work algebraically. Starting with one quaternion world line, 16 new ones can be generated by mixing up where t, x, y, and z go within the quaternion.
