……物理学位。所以确实有人在买一些书。不过当然了，出版的大多数书根本就没人买。我觉得 Lorrain 和 Corson 写的《电磁场与电磁波》（Electromagnetic fields and waves，我经手卖过的书之一）也就卖了几千本吧，而且我怀疑他们赚的版税都不够弥补他们为此付出的心血。对于学术教材作者来说肯定更惨，现在很多大学课程也不……
…physics degree. So some people are buying some books. But yes of course no one buys most of the books that are published, I don't suppose that Lorrain and Corson sold more than a few thousand copies of Electromagnetic fields and waves (one of the books I sold) and I doubt that they made enough money to pay for the work it must have cost them. It must be even worse for academic textbook authors nor that many university courses don't…
这行得通纯粹是因为教育工作者在同流合污。基础科学领域的大多数本科教材，隔上十年根本就不需要改版。我 1975 年学应用物理时用的那本 Lorrain 和 Corson 的《电磁场与电磁波》（Electromagnetic Fields and Waves），放到现在看依然一点毛病没有。
It only works because the educators are complicit. Most bachelors degree textbooks in basic sciences do not need to change from one decade to the next. My Lorrain and Corson Electromagnetic Fields and Waves from when I was studying applied physics in 1975 is just as correct now as it was then.
