Everything that we can see and touch is made up of particles, the basic building blocks of nature. Particles like protons, neutrons, and electrons compose the atoms of the computer or phone you are touching right now. ... Many technologies we commonly use today are the results of research spin-off from particle physics. These byproducts were developed to build and run experiments or to support the activities of the particle physics community. Two impactful examples include medical scanners used in hospitals and the World Wide Web. Both are indirect products of fundamental research conducted by particle physicists while conducting their primary research.  1, fiche 2, Anglais, - particle%20physicist

For all we know electrons and quarks are elementary particles, which means that in no experiment has there anything like a structure of these particles been seen. They appear point-like, unlike the proton, neutron, nucleus and atom that have sizes that can be measured. It is, of course, entirely possible that particles that are called elementary today shall turn out to be composite; let it be said though that they have been probed quite extensively. ... The aim is to know all about them, their properties and their interactions. The idea is that from this nuclear physics, atomic physics, chemistry, in fact, the whole physical world derives. Thus particles and their interactions are the very fundamentals of nature. That is the view now. An elementary particle physicist studies primarily these elementary particles and not the larger structures such as protons, nuclei or atoms.  1, fiche 3, Anglais, - elementary%20particle%20physicist
