Quarks came in a number of varieties - in fact, at first, only three were needed to explain all the hundreds of particles and the different kinds of quarks - they are called u-type, d-type, s-type.

Our view is that Quark can make almost everything smart. We'll show you some things that you would never have thought could become smart and communicate.
The top quark was discovered in 1995, and since then, the Higgs has become our obsession because the standard model was incomplete without it.
There's something called From 'Alchemy to Quarks,' which will teach you everything you have to know, you want to know, about physics.
We have our religious traditions coming from many thousands of years, and I think to myself, well, you know, if Moses had come down with tablets from the mountain that said, 'And guess what? There are protons and neutrons, and they are made out of quarks,' people wouldn't have understood what he said. So he didn't.
In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom, and eventually you discover quarks. Who would have thought that?
We had to understand things like why the top quark was so heavy and the electron is so light. The Higgs is a big, important step.
Indeed, the history of 20th century physics was in large measure about how to avoid the infinities that crop up in particle theory and cosmology. The idea of point particles is convenient but leads to profound, puzzling troubles.
Quark-antiquark collisions cannot be realized directly since free quarks are not available. The closest substitute is to use collisions between protons and antiprotons.
High-energy collisions have led to the observation of many hundreds of new hadronic particle states. These new particles, which are generally unstable, appear to be just as fundamental as the neutron and the proton.
In the lab, we could not see or physically describe the mathematical objects that we called quarks, which we suspected were the key to unlocking the dynamics of the strong force that binds together the clump of protons and neutrons at the center of the atom.
