    Approximating Pi and e with Linear Algebra

    You're excused... :smile: The somewhat mangled quote (I see now) was from Mathworld, that has oodles of info of why pi and e are not algebraic, but are transcendental. No contradictions, there... Maybe some first reading on algebraic, irrational and transcendental would be useful here...

    Approximating Pi and e with Linear Algebra

    Nagell 1951), and Liouville proved in 1844 that e does not satisfy any quadratic equation with integral coefficients (i.e., if it is algebraic, it must be algebraic of degree greater than 2). (Mathworld on e) almost the same goes for pi. [cutie of the month: pi(pi + 1/e - 1/(4(pi^3)))=...

    When will e-bits overtake bio-bits?

    Depends. The amount of memory it would take to accurately do a 1-on-1 simulation of 1 (one) human's visual processing would still be too much for anyone given super-computer... storage is not identical to direct processing. Saw the math done somewhere, and can remember being somewhat taken...

    Exploring the Multiverse: The Double Slit Time Experiment

    Interesting take on Young's experiment... http://physicsweb.org/articles/news/9/3/1/1?rss=2.0 wonder what that does to Mr. Deutsch's Multiverse?

    Permanently block certain processes anti virus

    Best thing would be do do a clean reinstall of windows from scratch, from disks that you know are clean. Then install antivirus program and firewall, and THEN connect to the internet. Not in any different order. That way you know you're clean. In SP 2 you will find the XP internal firewall...

    How can brain activity precede conscious intent?

    Step by step. Here's some more fun: :smile: http://www.nist.gov/public_affairs/releases/qubits.htm

    How can brain activity precede conscious intent?

    Maybe take a look at this, then (.pdf, bit slow download): http://www.cs.auckland.ac.nz/CDMTCS/researchreports/248cris.pdf because quantum randomness is not so clear-cut as you seem to think.

    How can brain activity precede conscious intent?

    [1] Before we stomp off in search of 'intelligent design' or introduce anthropic principles, I'd really like to know why life does not give up the ghost willingly, ever. We could just accept our fate right from the start and give into our eventual fate. We don't, and with a vengeance. Why...

    How can brain activity precede conscious intent?

    Oh, I see that. I'm a true believer in physics fascism vs. democracy. :smile: Seriously, if it is a statistical trend, we still try to go against the stream, I hope you will grant me *that*, at least. We'll do anything to try and prevent its effects, high and low. Now why would that be...

    Maxwell's Demon: Is it Worth the Read?

    As Chronon indicated, trickier than you might think, he? :smile: see also: (scroll down to 'A reset operation') http://www.demog.berkeley.edu/~dstein/complexity/maxwellsdemon.html and to get a glimpse of others struggling with the concepts...

    Can a random number generator predict the future?

    That's exactly what it is. Disraeli would have felt totally redeemed by these jokers. :zzz:

    What Are the Major Security Challenges in P2P Networks?

    Well, if that's a real life example, that would count as a violation of certain viewing rights in my book, so I grant you your worries over possible more hidden glitches in the software. What you cannot see you cannot hack, or at least not so easily. I also think they should be patching such a...

    How can brain activity precede conscious intent?

    They once performed an experiment on our close cousins, the chimpanzee, where they gave shocks to the animal with timed intervals. The animal developed stress syndrome with ulcers etc pretty quickly. Then they gave the next batch a button to call this shock upon themselves, which hurt...

    How can brain activity precede conscious intent?

    [1] Bent in the sense that if you keep the normal downward flow of entropy in mind, life has quite a distinct knack of trying to violate that trend. I also acknowledge that on a larger scale the 2nd law does not get violated, I'm not trying to go outside physics here in any way, but you will...
