1. Feynman had an IQ of 125, which is close to being the top 2%.
2. The only reason he scored so low was because he was bad at writing. The math/physics portions, he dominated. Read up on his mathematical ability and synesthesia.
3. If your only counter example to people having high IQs and correlating with intelligence is Richard Feynman, then you are only lying to yourselves about your low IQs.

What university do you go to, OP?

If you don't understand the concept of negative numbers then you're 2000 years less intelligent than the average 4th grader.

A strange mix of someone angry, yet apathetic... but mostly just pathetic.

I don't give a fuck what you're taking.

If you're in college math, you shouldn't complain about square root factoring and quadratics - you took those already in grade 11.

Welcome to high school.

Atoms have zero volume and they move.

Paper is 2D and has temperature.

You're wrong.

The derivative of

y = e^f(x)

y' = e^f(x) * f'(x) * ln(e)

What's the derivative of (sin(2x))^2?
Use the chain rule to make it
(2sin2x)(cos2x)
Then derive the 2x part of cos, which is 2.
So you have
2sin2xcos2x
2(sin(2x))(2cos(2x)) or 4sin2xcos2x
so, if y = e^((sin(2x))^2)
y' = 4e^((sin(2x))^2) * (sin2x)(cos2x)

>people trying to sound smarter than they are

OP is at the point, obviously, where he has not learned about that part of math yet.
So as far as he's concerned, you "cannot" log a negative number.

Jesus Christ.

...

You cannot log a negative number.
The absolute value of x, |x|, is always positive.
When you take the square root of x^2, you're left with + or - x since both numbers multiplied together give the same value, positive or negative.

That's why nobody mentions |x| - because it's fucking implied that you cannot put the negative value into the log and get a meaningful answer.

>>2490151
If OP couldn't grasp why you couldn't put a negative in a log, then he did need a calculator for it. THat's why I used one.

>>2490098
Because it's implied, you dipshit. You can't log a negative number.

Took out my calculator:

Do log8^2 = 1.8
Do log(8^2) = 1.8
Do 2log8 = 1.8

log(x^2) = 2logx

Spacetime is a model for which we understand things. There aren't three actual dimensions - they're just mathematical to make everything else we use to understand the universe make sense.
So what the guy is saying about time not being real is true.

1. If you make a car, you can only travel as far as your car dealership is from your house.

2. Time travel is not possible, will never be possible, and won't ever be done.

3. If it was possible, there'd be no arbitrary restriction like that.

4. Dyson spheres are science fiction. It's not feasible to do that, it's not efficient to do that, and it's not realistic to waste resources. Also, it's not a physically possible structure.

Uh, yes. Where have you been?

Use any scientific calculator.

Put in 25 and then press the OCT key.

Why was 6 afraid of 7?

Because 7 was a nigger.

Are there lots of job opportunities for someone with an undergrad in this? Masters in this? PhD in this?

How much do you make? Are you guaranteed work in your field?

What do you currently do? How much do you make? How old are you?

How "difficult" is this doctoral program? How difficult was your major? Where did you go to school for undergrad/master/doc? How much time does it/did it take up?

>doesn't have real world applications

First of all:
1. In high school, you're still learning the building blocks of the math you're going to need to use to have any real world applications. You're learning the theory so it comes to you in your sleep.

2. High school calculus has real world applications - it's called optimization. But even then, it's simply optimization. You still don't know enough math to have any practical use for it.

3. Anybody who doesn't realize this probably isn't smart enough to use higher math for practical applications, because the most obvious, every day things we do in life require some of the most complex math there is.
