The author Wan-Chung Hu(born1973) is a MD (National Taiwan University) and PhD (Johns Hopkins University). This book contains theories in physics, chemistry, biology, geosciences, and mathematics. Spinity is a force to drag spacetime to rotate around central mass. Rest mass produces gravity, spinning mass produces spinity; rest charge produces electricity, spinning charge produces magnetism. Gravitospinity Maxwell equations can be obtained. Light is also the gravity wave, and light decides time. Space-time has smallest unit as new Planck volume and Planck time. Flight principle is given. Lightity is dark energy. Photon emitted from galaxy expands the universe acceleratedly via light pressure. General relativity suggests mass induces spacetime curvature; charge relativity suggests charge induces spacetime torsion. There is no dark matter, and spiral galaxies are formed due to charge relativity which replaces quantum electrodynamics. Integrating general relativity, charge relativity, and light pressure, we get 4x4 universe field tensor. The birth and end of universe can be deducted. Unified field theory can also be obtained by integrating electric field, magnetic field, gravity field, spinity field, and temperature field. Combining gravitospinity, electromagnetism, and matter standing wave, I deduct a determinative atom model replacing quantum mechanics. In addition, I propose a new chemical bond theory according to the new atom model. Homochirality is due to co-catalysis of L-amino acids and D-sugars. Extinction is due to Milankovitch cycle. Earthquake is caused by abrupt light release from inner earth which explains electromagnetism/ ionosphere anomaly and intra-tectonic earthquakes replacing plate tectonic earthquake theory. Tornado genesis is related to charge relativity. In mathematics, I propose MilankovitchThis book is very important to earthquake prediction. Many nuclear plants of Taiwan are located near fault areas. If huge earthquake happens, it will cause detrimental effect. I used several nights and weekends to finish this book without affecting my normal work. I am still most interested in biomedicine including vaccine science. Both biomedicine and earthquake research can save millions of lives.
