1.1 INTRODUCTION Modern particle physics research is based on subatomic particles, including atomic constituents such as electrons, protons, and 2.1 Leptons. The objective of modern science is to prove where the Higgs Boson particles originate. The spectacular discovery of the Higgs boson in July 2012 confirmed a nearly 50-year-old theory of how elementary particles acquire mass, which enables them to form big structures such as galaxies and humans.

The primary advantage of string theory is that it gives rise to the gauge and matter ingredients of elementary particle physics and predicts the number of degrees of freedom needed to obtain a consistent theory. In Symmetries in Elementary Particle Physics (Ettore Majorana). Present model of the constituents of matter is that which are structuresless and point like. [51] Lectures in Elementary Physics. One of the important modern ideas of forces is that forces between particles arise from the exchange of particles. This was a great insight that was close to the modern understanding in several ways.4 But two points where their concept was wrong was that the atom was “totally solid” and “indivisible.” Physicists have arrived elementary particles A diagram summarizing interactions between elementary particles described in the Standard Model. These fields are wavy-like vibrations and differ from classical waves in According to the emerging modern consensus, there are no particles in the classical sense, just these fields. It may well happen that the limiting speed for elementary particles is not the speed of light, but some other speed a bit higher than the speed of light. A prime objective of the biggest and most expensive scientific experiment in history is detection of the Higgs particle, speculated to be the generator of mass for elementary particles. Darkened circles represent types of particles, and blue lines connecting them represent interactions that can take place. Coverage of all important topics such as Relativity, Quantum Mechanics, Nuclear Physics, Elementary Particles, Radioactivity and Zeeman Effect. Without Higgs Boson, scientists could not fathom how elementary particles have mass at all. €�The fact that it was seen more or less Modern equations seem to capture reality with breathtaking accuracy, correctly predicting the values of many constants of nature and the existence of particles like the Higgs. In quantum mechanics we have the unifying idea that everything in the universe is made up of relativistic quantum fields that correspond to elementary particles and which I will refer to in the future as simply fields. According to modern theoretical physics, the fundamental types of things which exist are quantum fields, and particles are merely excited states of the underlying quantum field. New York: [72] What is and what should be the role of scientific culture in modern society? A lepton is a fundamental constituent of matter i.e.
