Light particles - called photons - carry a packet of energy that depends on their frequency.

光束粒子——称为光子——携带的能量取决于它们的频率。

They are called quantum because it takes a packet of energy of a very specific size - a quantum - to create the states.

它们被称作量子因为物质只能接受一份份特定的能量——一个量子——来建立状态。

Kraft, an American food manufacturer, made Biskuat, an "energy biscuit" with lots of extra vitamins and minerals, into a bestseller in Indonesia by charging the equivalent of just 5 cents a packet.

美国食品生产商卡夫生产的Biskuat饼干，这是一种“能源饼干“，里面还有额外的维生素和矿物质，5美分一包的价格，让该饼干在印度尼西亚十分畅销。

And I use the term photon here, and that's because he also concluded that light must be made up of these energy packets, and each packet has that h, that Planck's constant's worth of energy in it, so that's why you have to multiply Planck's constant times the frequency.

我这里用光子这个词,是因为他还总结出光,必须由这些能量包组成，每个能量,包有这个h，普朗克常数代表,里面的能量，所以这就是为什么你们,要用普朗克常数乘以频率。
