“Any sufficiently advanced magic is indistinguishable from technology.”
Anonymous saying, this is an inversion of the third of Arthur C. Clarke's three laws : "Any sufficiently advanced technology is indistinguishable from magic." It has been attributed to Niven, and even called "Niven's Law" by some, and to Terry Pratchett by others, but without any citation of an original source in either case, and the earliest occurrence yet located is in Keystone Folklore (1984) by the Pennsylvania Folklore Society.

The smartest of my pupils would get all my attention, and the rest would have to fend for themselves. And I can’t handle being interrupted.
Writing is the answer. Whatever I have to teach, my students will select themselves by buying the book. And nobody interrupts a printed page.
