    Maxwell's calculations on electromagnetism's speed = light speed

    I do use a calculator. That is not my question. That is how I did the first calculations I posted here. And of course got the speed of light when I DIVIDED one constant by the other; took the ratio of the two with the electric constant as the numerator. Then taking the square root of that (on my...

    Maxwell's calculations on electromagnetism's speed = light speed

    What does "take one over that" mean?

    Maxwell's calculations on electromagnetism's speed = light speed

    mu symbol of course is the magnetic constant and epsilon is the electric constant. That I know. My problem is math. But one would have to be dividing them instead of multiplying them and I don't know how one does the math.

    Maxwell's calculations on electromagnetism's speed = light speed

    Thanks -yes I need to clarify. Look at the way I arrived at the speed of light from simply dividing the two constants and taking the square root of that. I saw that somewhere on the web. Then look at the more classic formula at the very end. That may be Maxwell's derivation or someone else's...

    Exploring the History of Physics: From the 19th Century to Quantum Mechanics

    Hello: I'm Bill McKay and a retired biologist. I've had a lot of science of course but not much physics (or math). I'm now studying the history of physics from the beginning of the 19 century so I can slowly go through it and up to quantum physics of today. Being weak in math, I'm reviewing math...

    Maxwell's calculations on electromagnetism's speed = light speed

    I'm studying history of electromagnetism. Here is my question regarding Maxwell's classical brilliant work. I understand these constants (for now) And I understand this: And I understand this: But I need to understand how this math below gets us to the speed of light. I don't understand...
