    Default How many Scientific Equations do you know?

    We've seen enough English games and tests. How 'bout the more scientific (some would say smarter ) bunch? How many of these 141 equations do you know, even if you can’t recall exactly each variable? Go by the headings. Within are just different arrangements and variations. In case you’re wondering I saw the same equation twice in the 142 listed (the frequency/ period relation).

    :O i was the first to vote. :O
    i took the plunge... now folk will see how strange i am... (most are from waves and optics, along with modern physics.) :3

    The descriptors are off. I took applied science in University as major, and had 90% in fundamental physics, but still only around 67.

    Holy, who’s the one with the 120-129? Too bad I can’t see those voters after voting myself.

    I studied most of the ones i know while studying other things... which they corelate. while some i learned in high school. :3 which even though some (which i didn't coount) i knew the name, but not the formula. ...and since you asked about how many formulas we knew... i went with the ones i knew... which came to be 32. (60 or so if you count the ones i knew about but not their formulas.)


    *suspicious eyes, this is one of my weaknesses in the world of knowledge. (my other two are, working and speaking.)

    I remember one semester, I thought the prof was killing us with the Biot-Savart Law. Turned out it was only a preface to the Faraday and Ampere Law later in the course. Students were chuckling with disbelief as the prof kept working out this one example in total abandonment.

    Somehow limited by the comparison to Hawking.....!

    I would happily admit to knowing hundreds of chemical equations. It's called my job.

    From the categories in the OP's linked list I only know one equation but can't find it in the form they present it. This is what I know:

    Watts = Amps * Volts

    I do know a few others but outside the categories in the OP's linked list.

    I know of the first one but don't know it to be able to do anything more than stare at it in awe.

    The second representation you have with the summation signs looks like it must be the formula for how my muscles cramp from old age.

    Oh I know that one again to stare in awe, but not to actually use it. But were these in the OP's linked list? I could not read it well. I think much was in other forms or Greek.

    I once knew the formula for calculating the viscosity of a mixture of two oils. It required log and antilog functions.

    scroll down all the way to modern physics and it should be the eighth one... or the fourth one on the second line... *nods it should be there. if not, i must be seeing things...
