    A major problem between them is trying to describe what goes on inside a black hole. GR ends up as a singularity. QM says impossible.
  2. mathematic
    1. All evidence points to accelerated expansion. 2. Singularity is a mathematical artifact. Physics is unknown. 3. Pre-big bang is pure speculation.
  3. mathematic
    It looks like the min and max occur when sin = 0 (0 or 180).
  4. mathematic
    Opposite version of black hole? What does this mean?
  5. mathematic
    Use inverse squarer relationship. Your description doesn't describe the motion of the first two relative to the third.
  6. mathematic
    It will depend on where the observer is relative to the meteorites. Speed of sound is not subject to Lorentz transformation.

    Zeno's paradox goes away when time is considered.

    Why is the name of a particular specialty important? I presume venomology is narrower than toxicology. Try Google.
  9. mathematic
    How about "unmasking"?

    The link appears to be a list of numbers - no picture?
  11. mathematic
    Draw a picture!
  12. mathematic
    My statement is about all (including complex) numbers.
  13. mathematic
    Every number (except 0) has two square roots. Using the convention (ignore negative root) leads to these kinds of problems. l
  14. mathematic
    square root of n(n+2) is approx. n+1.
  15. mathematic
    Non-empty open sts must have positive measure, so your approach to the first question is correct. The second question is almost from the definition.
  16. mathematic
    The second and third easily false. The two function could agree on the rationals, but not elsewhere. You need to use another deliminator for Latex $ doesn't work here [math] and [math] with / work.

    Looking at the original question (I have not plowed through the responses), the ball on chain can hit harder than the hammer because it can be made to go much faster before release.
  18. mathematic
    Pure speculation. High wind conditions could lead to evolution of very sturdy thick trunk trees which would mitigate winds and allow small (compared to tree size) animals to evolve.
  19. mathematic
    Mathematically sqrt(1) has two solutions +1 and -1. There is a convention that only +1 is allowed and the program may be set up to follow the convention.

    The point I am making is the speed of the electrons is irrelevant to electricity working.
  21. mathematic
    Most households use AC where the electrons jiggle in place.
  22. mathematic
    I don't get it!
  23. mathematic
    Is there a question? What are N, x, y?
  24. mathematic
    I hate to say this, but it sounds like meaningless wordplay.
  25. mathematic
    Sorry! Completely strange to me.
