So up to this point, before it was really established that yes, light is like a particle sometimes, there was this very strong distinction between what is light and what is matter.

所以关于这个观点，在它被真正确立之前，光有时候像粒子，在什么是光和什么是物质之间,有一个非常巨大的区别。

And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.

上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的，波动性和粒子性,和光的波动性和粒子性。

When it does so, each particle of matter produced is accompanied by an appropriate antiparticle.

ECONOMIST: Particle physics

CMB, and the number of subatomic particles in the universe, suggest that for every billion mutual annihilations, a solitary particle of matter survived.

ECONOMIST: Particle physics makes sense, but it assumes too much

In particular, every type of particle of which matter is composed has an equal and opposite antiparticle composed of antimatter.
