  • Suggested books for the course:
  • The notations used in vector calculus date back to the 19th century, and the works of Hamilton, Tait, Maxwell, Gibbs and Heaviside (mugshots below). See here for some discussion of the origin of the nabla (∇) symbol, and here for James Clerk Maxwell's 1871 paper where he suggests the word 'curl'.
  • In the unlikely event that you're finding index notation a bit too easy, or just to reassure yourself that things might be even worse, you can have a look at Penrose graphical notation, a.k.a. birdtrack diagrams (or fornicating ostriches). Birdtrack diagrams will not be in the exam! For abstruse goose's not-totally-serious take on these notational issues, see here, here, and finally here (but not if you're offended by strong language).
  • The (rather brief) entry in mathworld about the summation convention contains a quote from Einstein about his invention.
  • There's a discussion of multidimensional differentiability at mathinsight.org including some nice animated illustrations (which need Java, unfortunately).
  • Some nice pictures of three-dimensional level sets and their singularities can be found here.
  • To hear Will Self trying to get to grips with some bits of vector calculus, see (or rather hear) around 4:10 here.
  • Click here to see a Mexican hat.
  • Stokes' theorem was set as a question in the 1854 Smith's prize exam which was taken by Maxwell. It had been pointed out to Stokes by Kelvin in a postscript to a letter dated July 2, 1850; this is why it is sometimes called the Kelvin-Stokes theorem.
