Quantum physics Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very differently to macroscopic matter: particles can behave like waves, and waves behave as though they are particles. Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. ...
SCIENCE AND ITS ORIGIN Science is a systematic understanding of natural phenomena in detain so that it can be predicted, controlled, and modified. Science involves exploring, experimenting, and speculating phenomena happening around us. The word science is derived from the Latin word Scientia means 'To Know'. Scientific the method is the way to gain knowledge in a systematic and in-depth way it involves systematic observation controlled experiments Qualitative and Quantitative reasoning Mathematical modeling Prediction and verification of theories Speculation or prediction Science does not have any final theory. The improved observation, accurate tools keep improving the knowledge and perspective. Johannes Kepler used Tycho Brahe's research on a planetary motion to improve Nicolas's theory. Quantum mechanics was developed to deal with atomic and nuclear phenomena. Work of Ernest Rutherford on a nuclear model ...
