Re: Vectors without components

Since no one has mentioned it, I'll throw in my favorite example of a vector space that has no "obvious" basis (and indeed requires AoC to even show there is one): The real numbers as a vector space over the rationals. It's pretty tough to think of that one in terms of "coordinates&qu...

Re: Google loses privacy case

Twistar: You are correct, the induction step fails at n=2. The language gets just a bit vague at that point (of course), so it's tricky to say exactly which statement is false. You could interpret "h has the same color as the other horses" to mean all horses besides the one tha...

I've always liked the proof by induction that all horses are white: Theorem: For any (finite) set of horses, all of the horses are the same color. We prove this by induction on n, the size of the set of horses. Base case: n=1, obviously since there's only one horse in the set it has just one color. ...
