[...] phase φ = 0, and negative real numbers correspond to complex numbers with φ = π. We also get Euler’s formula, which I wrote about in a previous blog post:This is one of those really interesting formulas, since it takes two irrational numbers (e and π) [...]

[...] Hamilton was walking along the Royal Canal in Dublin. He had been pondering for a long time whether complex numbers could be extended to higher dimensions. During his perambulation, he realized the answer was [...]

OT, but I contend that obiter dicta are always fair game for a response:

How would an Anglophone pronounce the name apart from

“oiler” (in the local accent of English)

full German pronunciaton (in accent of choice)

something more or less ludicrous (Cf. BBC announcers talking of jag-you-ars in Nick-a-rag-you-a)

With apologies for my nationalistic mood this morning. In all fairness, I think that BBC Standard may call for a reasonably realistic pronunciation of Vincent van Hokkh, so universally mangled by Americans as Van Go. And as for pronouncing Huyghens, forget it — can’t be done anyway.

Great treatment of Euler’s gem, by the way.

My high school math teacher told us about this equation that in it we could find historical numbers important in the development of conceptual mathematics: Negative numbers were created to answer a – b where b > a; imaginary numbers were created to answer sqrt(-a); pi was linked to Pythagoras and his school of thought derived from Plato’s; e was the answer to finding a curve which had at every point a slope equal to the function value at that same point.
Truly an elegant equation, exiting and as you put it, striking.

You have a nice blog. Keep it up
