Whether these were quarks or something else was not known at first.

"How can the same quarks and things be in all of them at once?"

This is because quarks are held together by the color force.

There has to be something different about these quarks, he thought.

In his mind, I was obviously made from the wrong kind of quarks.

Thus, a time machine is needed to see most quarks.

The few remaining quarks became the matter of which we are made.

Quarks are very small things that make up everything we see (matter).

Everything from quarks to matter to energy to ideas can be looked at in this way.

Because top quarks are very massive, a lot of energy is needed to create one.

The two new quarks are eventually named top and bottom.

That is for the up and down quarks in the nucleus.

We cannot study quarks alone; they are always inside something, which makes it very complicated.

They seem to play an important role in the confinement of quarks.

Only up and down quarks are found inside atoms of the normal matter.

Because the quarks are confined to each other, and it takes a lot of force to break that.

She let herself almost sing the words, an attempt to focus Quarks attention on her.

Does this explain why we don't see quarks on their own?

The images, he said, will pick out only certain quarks, like a photograph taken through color filters.

Quarks and electrons are thought to be made of strings.

But were quarks and leptons the end of the story?

But the quarks will not come out and roam freely.

Inside, there are quarks, though we can't see them directly.

This is because quarks, unlike electrons, come in many species.

Sound involves matter on rather large dimensions, compared to little quarks.
