    Conservative vector field conditions

    My calculus book states that a vector field is conservative if and only if the curl of the vector field is the zero vector. And, as far as I can tell a conservative vector field is the same as a path-independent vector field. The thing is, I came across this...

    Is this a Valid Syllogism?

    I see. Any other takers?

    Is this a Valid Syllogism?

    Perhaps I was subtle in my actual question (bad title name). I wanted to see if the O-claim really is distributed, as my textbook says it is. I don't believe it is. So, I set up a syllogism to test it. The syllogism is made to have the O-claim's predicate distribute the middle term. So, if the...

    Is this a Valid Syllogism?

    Is this a valid syllogism? O: Some A's are not B's. O: Some C's are not B's. I: Therefore: Some A's are C's. For some reason this doesn't look correct. When I tried to put an example of this syllogism, I got a conclusion that was false, from two premises which are true. Here is that...

    Question about voltage in terms of dipoles

    If we have two charges, one at, say, 1C and one at, say, -1C, and they are separated by a distance of 1 meter, why is the voltage directly between them zero? A positive test charge will move towards the negative charge, and gain kinetic energy, but it started with no potential energy, and...

    Cause of the Electromotive Force.

    In an electric current there must be forces that push electrons in a general direction (current). My question is, what creates this force (electromotive force)? I assume that this force, that moves electrons, is created by a surplus of electrons in one area. Perhaps they move because the...

    Defining Supernatural & Natural: Quantum Physics & Beyond

    1. What is supernatural? What is natural? I'm having trouble giving definitions to these words. What definition could we give these words? I have some ideas for defining these words, but I'm having second thoughts about them. I was thinking that we could call concepts that were supernatral...

    Can we predict a complex molecule's shape?

    By complex, I mean that there are a lot of atomic parts. Water is a simple molecule. Methane is a simple molecule. A complex molecule would be something like glucose. An amino acid is even more complex. And a simple protein is even more complex. Can we predict a protein's shape by knowing the...

    Can we predict a complex molecule's shape?

    I've recently learned that we can predict the shape of molecules with a small amount of atoms. Can the shape of a complex molecule with many atoms be predicted too?

    Objective Opinion: Is It An Oxymoron?

    I agree, this was what I've always thought an opinion was. But people use it in many other ways, and in a discussion, it gets pretty annoying. "Ice cream is good" is what I would consider an opinion because it's subjective. "I am fifty meters tall" is fact because it's objective, even though the...

    Objective Opinion: Is It An Oxymoron?

    Is "objective opinion" an oxymoron? I've always thought of opinions as being subjective. Thoughts?
