pThe Unity of Science presents a unique overview of natural phenomena and foundations of different technologies chemistry, electronics, optics, etc.. It explores the connections and unified foundations of diverse scientific and technological fields. The author explains how much of Nature at the very small and very large scales and most of our technology can be understoodderived from a few basic principles or concepts Newton and Coulomb's laws, special relativity, Schrodinger's equation and the concept of entropy. ppAdditional features include pul p p liUses a systematic derivation of Statistical Mechanics from information theory, a connection central understanding the brain and the functioning of Deep Learning networks. li p p liExplains how combining special relativity with electrostatics allows one to understand magnetic phenomena. li p p liDetails how the unification of special relativity with QM allows one to understand the origin of anti-matter and spin Dirac's equation.li ulpThis
