Some of their work involved X-rays produced by particle accelerators, devices that bring atomic particles into high energies.

So, then we'll get to turn to a new kind of mechanics or quantum mechanics, which will in fact be able to describe what's happening on this very, very small size scale -- so on the atomic size scale on the order of nanometers or angstroms, very small particles.

然后我们要讲到一种,新的力学--量子力学,它可以解释,发生在很小尺度,大约是原子尺寸大小,也就是纳米或埃的量级。

The website is overseen by a group of working physicists, but you don't need a Nobel Prize to join in the adventure of sub-atomic particles.

This could shrink the size and cost of building giant accelerators, which produce sub-atomic particles.

The Standard Model is a framework that explains how the known sub-atomic particles interact with each other.

The loop may produce sub-atomic particles with a thousand times more energy than those in man-made accelerators.
