Quantum theory and Lorentz structure are the twin pillars of fundamental physics today. With quantum theory kept and Lorentz structure replaced by Euclidean Jordan algebra --- a more fundamental structure, one naturally arrives at the notion of abstract fundamental matter particles. These abstract ...
One of the dangers of particulate matter, especially the fine type, is that it can be inhaled. If the particles, which can be composed of any combination of hundreds of chemicals and elements, are able to get through the defenses of the nose and mouth, then they can find their way into...
(PM).Other types ofPM include coarse particulate matter (PM10) and fine particulate matter (PM2.5).Witha diameterof 0.1 micronorless,UFPsare the smallestknown particles of PM.To put its relative size into perspective, UFPsmeasure 700 times smaller than the average diameter of a...
While protons, neutrons, and electrons are the building blocks of atoms, these particles are themselves based on fermions. Quarks and leptons typically aren't considered forms of matter, although they do fit certain definitions of the term. At most levels, it's simplest to state simply that ma...
which combine with Fermions to form the building blocks of matter. There are six leptons in the present atomic model: the electron, muon, and tau particles, and their associated neutrinos. The different varieties of the Lepton particles, commonly called "flavors", are differentiated by their size...
