Wolfram Alpha proves that N = N - 1

  This is very dubious (proving the opposite is easier), but it was quite a lot of fun.

    I can see how it may have been fun, but it doesn't even really rate as dubious. Not only is one of your premises (a/a = b/b -> a=b) clearly false, but your conclusion doesn't mean anything. a=b ^ a=b -> n=(n-1) ^ n!=(n-1) is just a contradiction. Your first and second terms together imply n=(n-1) which directly contradicts your third term. I'm afraid you've simply proved a contradiction, which just means (because of, well, proof by contradiction) that you're arguments are flawed.

  . . . but you can't tell anyone about it except by linking to it, because Wolfram Alpha copyrighted it.
