Plagiarism

My wife is busy today marking students' assignments. The subject is vector cross products and dot products. Someone in the class came up with some new maths, best described as vector division, which seems to involve lots of canceling out, but really simplifies the work.

What is really sad is that half the class has adopted this new math. Apparently its easy to spot the originator of this concept because her paper is full of crossing outs and scribble. All the others are neat duplicates of the original cutting-edge work.

Sad. Really sad. Fancy getting caught out like that.
