The manner in which particle physicists investigate collisions in particle accelerators is a puzzling process. Using vaguely-defined “detectors,” scientists are able to somehow reconstruct the collisions and convert that information into physics measurements. In this video, Fermilab’s Dr. Don Lincoln sheds light on this mysterious technique. In a surprising analogy, he draws a parallel between experimental particle physics and bomb squad investigators and uses an explosive example to illustrate his points. Be sure to watch this video… it’s totally the bomb.

Does detector surface need to be replaced since they should be altered by all the subatomic particles that goes through them (i mean it must somehow change the purity of the material of the detector)?

How do you identify the subatomic particle ( hadron, neutrino, electron) shot through the accelerator being that it’s so subatomic?
@MuttFitness
@MuttFitness 4 жыл бұрын
They mostly don't detect the neutrino. The electron would be detected by something that detects either magnetic fields or electric fields or photons given off by the electron. Not sure about a Hadron.

He helped build an emergency exit door that weighed tons yet could be opened by a kid because it floated using hydraulics. He also built surveying scaffolding for when the trench was being poured for the loop. Let me know if you're interested in obtaining it.

An orchestra is designed to play set scales in any order of notes and chords, and do so according to the composition they are directed to, from the imagination of the composer. The story is, that Beethoven wrote the 9th after he was deaf, which is something like designing a physics experiment for a collider? And Mozart could write out a composition from a single idea, explosively? Is that where "Mystro" trained ?

@@gregmonks A detector fires under certain circumstances. In your case, you want it to fire when a proton passes the detector. Unless you are very careful, the detector will fire when other particles travel through it as well. Unless you know how to reject them, these would be considered fake protons. It's not much different than from one of those animal cameras that are left in the woods. You want to take pictures of deer. However, unless you are able to teach the camera to select only deer, you will also detect squirrels, rabbits, dogs, etc. Now for the animals, you can look at the pictures and separate out what you want. It's more difficult to do that when you are searching for protons.

Hadrons are a class of particles consisting of quarks and/or antiquarks, such as baryons (consisting of three quarks), including protons and neutrons; and mesons (consisting of a quark-antiquark pair), including pions and kaons. On the other hand, leptons - electrons, muons, and tauons - are not hadrons, they are (as far as we know) elementary particles themselves.

It is a good analogy. But the room only tells a fraction of the story. There is so much going on in that controlled explosion, that we know of, and was not registered in the room. This same analogy aplies to particle physics. You are only fragmenting plasmoids, into smaller plasmoids. You need to start considering the speed of light in such small scales. A photon (a plasmoid) can orbit another photon, more than 70 billion times over a Planck Second. That is how two photons make an electron.

how are they able to detect a Higgs Boson?
@MikeRosoftJH
@MikeRosoftJH 6 жыл бұрын
Basically in the same way. They perform a particle collision, observe the products of the nuclear reaction (or, more accurately, the effects thereof), and from that they calculate the properties of the particles involved. So they concluded that they have detected a particle, with such and such mass, spin 0, no electric charge, and so on, which very quickly decayed into a particle-antiparticle pair. And the properties and behavior of the detected particle matches the predicted ones for the Higgs boson, so they conclude that it is one. (Of course, they repeat the experiment many times to make sure that it is not just a statistical fluke.)
