  1. In Topic: Perelman's solution

    A disclaimer that I haven't done topology in a good few years now, but whilst it's true that properties which are preserved in a topological sense are important and useful, techniques involving gluing or cutting can be used just as well too. Topological constants aren't everything :)

  2. In Topic: HELP... ! to convert SHA1 Hashes

    15 June 2011 - 09:16 PM

    Rainbow tables are useful for reversing hashes, but they're rendered fairly inert by use of a salt which is stored with the hash. Wikipedia has a pretty good entry on them.

  3. In Topic: Help! Differential Equations and Escape velocity!

    I think that they are making the observation that r is very large (and much bigger than R^2). Therefore the first time is very close to zero and thus ignored.

  4. In Topic: Starting Mathematics on my own! :)

    Honestly, if I were you, I would look into taking a basic course. Looking back on when I taught myself some more advanced topics throughout school, I found that I wouldn't spend enough time truly understanding certain aspects and had a tendency to move too quickly through a syllabus. Having a course gives you a set structure to work with, and allows you enough time to absorb and understand the material.

    Anyway, good luck in any case!

  5. In Topic: HELP... ! to convert SHA1 Hashes

    Hah, fair enough - it's not often you get a lawyer posting to these kinds of things so I will bow to your superior knowledge of this :P

    Hey am I messing up? I just joined? I went to Astronomy rather than speculation. But the conversation has been pretty awesome. This is a great place to discuss ideas.

    I wish to complain about Mokele. As a moderator he is picking on me and not in any way being impartial. I do not think he is a suitable moderator.
