Relation Between Computers, Light and Pi

  1. Jun 18, 2015 #1
    Is this equation of any use or in any way interesting?


    c = speed of light (m/s)
    e = euler's number

    I don't know much about physics but

    2^6=log_2(64), this is a binary logarithm so would this mean that computers, the world (c and e) and circles(pi) all be related somehow by this equation?

    Yes, we've all seen things like that.

    Just because something makes a good approximation, doesn't mean that there is a relationship.

    No. This is just numerology. Look what happens if you change units.

    It is not dimensionally consistent so there is no point to ask about usefulness.
    It does not make sense at all if c is a physical quantity and not just some arbitrary number.
    Speed of light is 186 000. In miles per second. Does you relation still "works" with this number?
    If you had a valid equation, changing units will not affect the validity, as long as you do it consistently.

    This totally brings me back to when I lived in England and argued with a guy in a pub about Pi. He insisted that Pi *is* 22/7. Obviously me trying to educate him about irrational numbers was of little value.

    EDIT -- We do not discuss numerology here on the PF. Thread will remain closed.
