    Understanding differential equations backwards

    im not wanting anything specific like "2", to be analagous, I do know the equation of a number like two is a straight, flat line. I know what an exponential equation looks like,... I'm looking for any generalities I can pick out

    Calculating Avogadro's number from scratch

    When the word "mole" first came into the scientific community; the proof of that paper that showed what this "mole" was, that is what i am looking for.

    Understanding differential equations backwards

    What I'm saying is are there any distinct "signiture" DE graphs? I am saying the opposite of you last statement, I am saying looking at a surface first then saying ah yes, differential equation over here! though, i really don't need to deal with 3d, 2d is sufficient

    Understanding differential equations backwards

    exaclty. Overall, I would like to better understand how to spot a differential equation represented by a) a graph b) good real life examples (a lot of times the graph is the thing we do last in a DE question. Are there any graphs that are distictly and definately a DE?/ how do you know)

    Understanding differential equations backwards

    understanding differential equations "backwards" Ok, so D.E. all all fine and dandy, heck I've taken a whole course of D.E. in 2nd year university and even did not too badly. While I did alright, I can't say I fully enveloped the big picture of the situation at hand that comes along with D.E.s...

    Calculating Avogadro's number from scratch

    So the accuracy basically increased the better we could actually measure the mass of the molecules? We are gettin to more to the heart of my question now... Basically I've done all sorts of university chemistry several years ago, but I never had time to question things deeply, now it' truly...

    Calculating Avogadro's number from scratch

    So in point form, what do i have to do in order rather than not do?

    Universal speed of gravity attraction?

    In theory: If mass is created all the sudden, how long does it take for another pre-existing mass to "feel" the new one? is this dependant on the medium through which the "pulse" travels? would it be instant? would it be light speed?

    Calculating Avogadro's number from scratch

    interesting stuff, thanks for the replys. I've never heard of the oil drop experiment til now. So to summarize so far: IF i get thrown back in time to 1700, in order to prove the Avag. #, I would first have to discover the "kilomolar" mass of a substance (How could I do this using the...

    Calculating Avogadro's number from scratch

    Your equation of course makes a lot of sense. Using your analogy my gap in knowledge lies not in the logic of this formula, but rather how would I go about proving/figuring out that Natruim is monoatomic. Forgetting fictional elements, how could I do a working example with C12? When...

    Calculating Avogadro's number from scratch

    Hello there, Not that I actually want to do this but theoretically I would like to know how I could prove to myself avogardro's number using only the most primative knowledge of math, physics and chemistry as possible. It all makes sense in whatever text you are reading, but it never gets...
