Might as well ask what affect emotion has on normal speaking, because the indicators of emotion in any uttering is probably the same. I believe they are exaggerations in pitch and tempo mostly.

Why is it when I'm outside in the 90 degree weather the air feels incredibly hot, but when I get in my car and roll the window down and drive along the air blowing against me feels cold? The only difference is the air is moving across my skin, right?

Let me try to give a definition of creativity--the ability to come up with particular solutions to a problems with multiple possible solutions. "Problem" and "solution" are used very generally here. An artist faces an empty canvas, a scientist attempts to create a theory that properly fits the...

The oldest human found is 150,000 or 160,000 years old, if I recall correctly. It strikes me that "civilization" (farming, large structures, etc) is < 10,000 years old(?). Is this because there simply weren't enough of us in a concentrated area to establish one? Supposedly civilization...

First, I apologize for using confusing terminology. What I perhaps have trouble understanding is why this "4-velocity" must equal c.

Long ago I accepted that the speed you move through time is personal, but I've always wanted to really understand it intuitively. I think I'm almost there. Suppose me and my ghost are in the same place initially. Now I take off running in a direction, but my ghost remains behind. Since I'm...

Thanks, that was helpful.

How does the second term in a quadratic, bx, affect the graph?

I just meant, would the object go right through our spaceship, most likely killing us? Or would we go right through it, destroying it but being mostly ok?

Suppose we were tasked to make a spaceship of some sort that could go really fast like 1/10 c or so. Now we want to space travel. What would happen if we hit something like one of our probes or a piece of rock? Game over?

In a computer a program is data. This is the idea that out modern computer is based on. It can be programmed arbitrarily. chroot, you said "other kinds of systems, like neural networks"... aren't neural networks the current model of the brain?

Go! Actually I want to pose this hypothetical question: If you wanted to self-learn most of the higher level mathematics most efficiently, starting with a calculus level knowledge, how would you go about doing it?

Energy isn't a thing. It's a helpful mathmatical device. You define a system and use conservation of energy to say stuff doesn't just happen without reason.

What is the best way to self teach yourself math beyond a calculus textbook?

You can buy this special cue ball, it's white and chalk sticks to it more readily. It has a coordinate type design on it. If you place it on the table at the same orientation every time, and wipe it off after every shot, you can see where you hit the cue ball. This will help you hit the ball...
