Re: XKCD april fools

My favorite so far is "who" followed by "whoami".

I was hoping for a command like "thisisunix" followed by "I know this". XKCD has been void of Jurassic Park references lately...

I chose LISP. As far as languages for scientific computing, it all comes down to what the research group is comfortable with as a whole. For this reason, FORTRAN, C and PERL seem to be the big ones. The thing that I dislike is that JAVA is starting to be used. A lot of work at the LHC is being done ...

Though I doubt they will answer your question, you might want to look at http://en.wikipedia.org/wiki/Real_projective_line and http://en.wikipedia.org/wiki/Extended_real_number_line Edit: and to answer your question think about inf*(1-1) and inf-inf You would want the first to be 0, and I would wan...

1 ----- * (x-1) * 1337 (x-1) 1 ----- * (x-1) * 42 (x-1) Now plug x = 1 into them. You get zero for that second term, and since 0*1337 is 0, and 0*42 is 0, they both simplify to the same thing. And they are both of the form infinity times zero. So they equal each othe...

1/infinity does not make sense. People just have to agree on its value. Most of the time it is 0. The limit as x approaches infinity of 1/x, is just analysis. It is just an approximation or it just describes the end behavior. People don't agree on its value, as it doesn't have a value. You can't di...

1/infinity makes as much sense to me as the limit of 1/x as x approaches infinity. At least without a definition of what we are dealing with. I think it is good to point out that infinity is an extremely useful symbol. However it is not an element of the set of real number (or natural or rational,,,...

One thing I have got to ask, as the answer I give will depend on what you are talking about, is are you talking about multiplication of objects or sets? 0*inf seems like you are talking about multiplication of objects. This does not yield the null set. Also, A*B = null set is kind of wierd too (I wi...
