SubstancesPrimary matterThe extremely successful Standard Model of Particle Physics allows one to define the so-called Elementary Particles . From another point of view, how can we think of them? What kind of a status can be attributed to Elementary Particles and their associated quantised fields?
Matter can exist in various phases: solid, liquid, gas, or plasma. Most substances can transition between these phases based on the amount of heat the material absorbs (or loses). There are additional states or phases of matter, including Bose-Einstein condensates, fermionic condensates, and qua...
