NASA Missions Provide new Insights into ‘Ocean Worlds’ in our Solar System
NASA researchers are on a quest to take the boom out of sonic booms, a development that could lead to a new generation of supersonic aircraft and perhaps even usher in a new era of supersonic passenger flight. On January 24, the Midsouth Chapter of the Academy of Television Arts & Sciences awarded NASA TV and the Marshall Space Flight Center with the Governor’s Award for Lifetime Achievement in recognition of NASA’s 50th anniversary. Drake Deming, an astronomy professor at the University of Maryland who has studied planetary atmospheres as a scientist for NASA’s Goddard Space Flight Center. “Energy Unlimited,” by Henry Bortman for New Scientist Magazine, pp32-34, 1/22/2000. Feature article on our vacuum energy project using MEMS devices to measure vacuum energy. “Quantum Starship hits the slow lane” by M. Chow, New Scientist Magazine, pp 20-21, 5/24/2003. Based on our article about a spacecraft that accelerates by pushing on the vacuum, and extracting energy from the vacuum to operate. And the team measured gases released from the assembly as it transitioned from normal air pressure to a vacuum — the same phenomenon that has led astronauts to report that space smells gunpowdery or metallic.
The design phase of the program is budgeted at $2.4 billion, inexpensive by space standards. Gas bubbles form in the cell plates, reducing the total amount of available cell space for recharge. Wedding form to function in window treatments can present a fun challenge if you have an odd-shaped window. By using SO(4,2) methods, we are able to obtain a generating function for the radiative shift for all levels. It explores radiative effects in classical and quantum systems from different perspectives, with the emphasis on understanding the fundamental physical phenomena. A first-order QED calculation of the complex radiative shift for a spinless electron is explored using the equations of motion and the mass2 operator, describing the fundamental phenomena involved, and relating the results to Feynman diagrams. Exploring the symmetry of the most fundamental two body system has led to advances in atomic physics, quantum mechanics, quantum electrodynamics, and elementary particle physics. 24. “The Role of Vacuum Fluctuations and Symmetry in the Hydrogen Atom in Quantum Mechanics and Stochastic Electrodynamics,” G.J.
We look at the issues of the H atom and SED from the perspective of symmetry of the quantum mechanical Hamiltonian, used to obtain the quantum mechanical results, and the Abraham-Lorentz equation, which is a force equation that includes the effects of radiation reaction, and is used to obtain the SED simulations. Radiation is a process common to classical and quantum systems with very different effects in each regime. We contrast the physical computed effects of the quantized electromagnetic vacuum fluctuations with the role of the real stochastic electromagnetic field. In a quantum system, the interaction of a bound electron with its own radiation field leads to complex shifts in the energy levels of the electron, with the real part of the shift corresponding to a shift in the energy level and the imaginary part to the width of the energy level. We give a unified treatment of the bound and continuum states in terms of eigenfunctions that have the same quantum numbers as the ordinary bound states. In this pedagogic review, we present the history of and an integrated treatment of the symmetries of the Schrodinger hydrogen atom, including the classical atom, the SO(4) degeneracy group, the non-invariance group or spectrum generating group SO(4,1), and the expanded group SO(4,2).
Engineers and scientists must produce pure hydrogen from hydrogen compounds, including fossil fuels or water. The most celebrated radiative shift is the Lamb shift between the 2s1/2 and the 2p1/2 levels of the hydrogen atom. 26. “Dynamical Symmetries of the H Atom, One of the Most Important Tools of Modern Physics: SO(4) to SO(4,2), Background, Theory, and Use in Calculating Radiative Shifts,” G.J. 23. “Effect of quantum and thermal jitter on the feasibility of Bekenstein’s proposed experiment to search for Planck-scale signals,” G.J. Brown and G.J. Maclay, published 21 years after the work of Casimir, was especially significant from a theoretical point of view, a kind of milestone on the road leading to the modern Quantum Field Theory interpretation of the Casimir effect. L.S. Brown and G. J. Maclay, published 21 years after the work of Casimir, was especially significant from a theoretical point of view, a kind of milestone on the road leading to the modern Quantum Field Theory interpretation of the Casimir effect. For the first time, it contains the local interpretation of the Casimir effect, in terms of vacuum energy and vacuum pressure… The results obtained served as a starting point for future developments of applications of the Casimir effect in MEMS systems…
