10 Colliders: What Are They For?

Colliders: What Are They For?

Posted on May 18, 2011 by team


Even the ancient Greeks believed that substance consists of tiny particles called atoms. The word "atom" means "indivisible" in Greek. However, with the development of science, it became clear that neither an atom, nor a proton and neutron are truly elementary particles. They consist of the smaller ones - quarks. Then neutrinos and antiprotons were discovered and now science knows about 400 different particles. To study their qualities and structures the mankind invented a very smart device - a collider. Let's look at some of them and learn how they function.

Since the middle of the 20th century colliders have become the main way for searching and studying these particles.

The idea of their functioning is quite clear. Imagine that you have two cars and know nothing about their inner structure. You speed up these two cars toward each other and face them. At low speed an impact will be weak and the cars will be only slightly deformed. But at a higher speed the impact will be stronger and as a result various light exterior details (such as pieces of lamps, windows, mirrors and bumpers) will break off the cars. You will catch these details, examine them and get some information about the structure of the cars. With an increase of the power of the collision, more and more heavy details will fall off the cars, and you'll get more and more knowledge about them. So in that way accelerators allow us to obtain new information about the particles.

Nowadays, a great number of colliders operate all over the world. some of them can speed up only small cars, while others can deal with heavy and huge trucks.

    This is where science gets really fun.

    For me looks like Babel architecture…

  3. CCCP says:

    first collider!

  4. marxistworker says:

    The SSC was abandoned in central Texas (due to budget considerations) and the money went instead to the Int. Space Station. A bad decision if there ever was one. But the ignorant Amer. pols who did this chose the Space Station because it was “glamorous.” Discovering the fundamental laws of the Universe was trumped for high school science experiments in low Earth orbit. That’s American anti-intellectualism.

    Put a Democrat and Republican in there and fire away! Like matter and anti-matter?

  6. cyberguy says:

    “atom” in greek means “person” not “invisible”…

    • Name says:

      “From Old French atome from Latin atomus (“smallest particle”) from Ancient Greek ἄτομος (atomos, “indivisible”) from ἀ- (a-, “not”) + τέμνω (temnō, “I cut”).”

      • cyberguy says:

        as you have already mentioned from ἀ- (a-, “not”) + τέμνω (temnō, “I cut”).”

        it means the one who cant be divided. I dont know where you have found your reference, but allow me to know better as I am greek ;)

  7. testicules says:

    vodka and caviar collision is what I vote for.

    I’m Greek and Atom (“atomo” in Greek) means indivisible (not invisible as you say). Tomi = section a-tomo = that which cannot be divided in smaller section.

    Atomo also is the individual which is why you think it is the “person”
