One of Updike's most famous series is about a man named Harry "Rabbit" Angstrom.

If I take lambda equals one angstrom, hc/lambda go through hc over lambda, you will discover that the energy of a photon with one angstrom as its wavelength is on the order of 12,400 electron volts.
如果我让波长等于一埃,能量为,你将发现光子的能量,当其波长为1埃的时候,相当于12,400电子伏特。
It is not an SI unit because it is not a multiple of 10 to the 3rd, but I like the angstrom.
它不是国际制单位,因为它不是,10的3次方进制,但我还是喜欢这个单位。
This is what's called the Bohr radius, and we'll explain - hopefully we'll get to it today where this Bohr radius name comes from, but for now what you need to know is just that it's a constant, just treat it like a constant, and it turns out to be equal to or about 1/2 an angstrom.
它叫做玻尔半径,我们后面会解释,希望我们今天可以讲到,波尔半径这个名称的由来,但现在你们只要记住,它是一个常数,只要把它当做一个常数对待,它等于,或者是1/2埃。
Gee, I wonder if I could come up with a set of transitions occurring inside atomic hydrogen Just right match that what Angstrom measured back in 1853.
嘿!我想知道我是否可以想出,发生在氢原子内的,一系列的跃迁,正好符合,阿姆斯特朗在1853年测得的东西。
