    How to understand something you don't know/cant get

    I was reading a biography of Richard Feynman, and when his sister was around 13 - 16 (I think) he gave her an upper level textbook on physics to read. She told him, I don't understand any of this. And what he told her to do was read until you stop understanding and then start again, this way...

    What Would You Pay? A Thought Experiment

    This interesting thought experiment was brought up by my philosophy TA last week and I thought I'd pass it along in hopes for a lively discussion. The game is as follows. You flip a coin. H TH TTH TTTH ... $2 $4 $8 $16 If you flip heads, the game is over and you...

    The speed of light and the mass of a photon

    One interesting development is called "Doubly Special Relativity", (the only person I recognize who was a part of it is Lee Smolin). Where they expand on Einstein's Second Postulate about the absolute nature of the speed of light, and replace it with an upper energy bound. This doesn't really...

    Are There Limits to AI's Replication of Human Emotions and Intelligence?

    Yes, I would agree with you there. Furthering technology does not require emotion or conciousness. I don't think anyone would disagree with that. What I'm arguing is that its possible that future generations of AI could develop these features independent of what we require from it. Perhaps I'm...

    Are There Limits to AI's Replication of Human Emotions and Intelligence?

    But the thing about the eye is that its flawed. We design the camera to be better. The human body is not by any stretch of the imagination a perfectly functioning system. So I don't see your argument... The argument here is whether AI systems CAN develop emotions and conciousness, NOT whether...

    Projectile Motion: Time and Impact Velocity Comparison - Homework Question

    Now if you throw in air resistance, and assume the balls are identical, think about what would happen to the times then.

    Are There Limits to AI's Replication of Human Emotions and Intelligence?

    Just looking at the evolution of humans and the brain, we already have a billion year head start. So to think that we could compress that process into a matter of decades might be unrealistic. But, I think if clever enough software and powerful enough software were set up so that a computer...

    How Are Polar and Cartesian Graphs of \( r = e^{\theta} \) Related?

    Derivatives with respect to \theta. I'm not sure, at this point I'm just grasping at answers. Any other thoughts?

    Solving Trigonometric Equations

    For the pendulum, think in terms of trigonometric functions. If you set the rest position to (0, 0) and you know the radius is 0.5 m, for what values of \theta will the height be 1 cm? Once you figure that out, you can find the times fairly easily. Ok so: m = \frac{5 \sin{120\pi 1.001} - 5...

    Having trouble with double integrals in polar coordinates?

    sorry, just to clarify.. r = \frac{1}{9 \cos{t}} for -\pi \le t \le \frac{\pi}{2} and r = 1 right? For the lower bound on r, I believe it is \frac{-1}{9} , but I'm not entirely sure about that, maybe someone else can look at this. In terms of the iterated integral here's a few tips: x = r...

    Having trouble with double integrals in polar coordinates?

    again it would be helpful if you gave the context. the radius is just the distance from the origin. where do the double integrals fit in?

    Solving Trigonometric Equations

    I assure you the answer is not zero, make sure your calculator is in radian mode, and make sure you keep track of your negatives.

    Solving Trigonometric Equations

    Yes, that's a pretty close approximation and will give you an answer within 2.35 % of the exact answer. Question, have you ever done any calculus before? (and yes, I do realize this is the precalculus section)

    Having trouble with double integrals in polar coordinates?

    Maybe if you gave the equation you'd get something more definite. But for polar coordinates what i'd do personally is convert it to a set of parametric equations and integrate those separately with respect to the parameter. R is usually given by a polar equation, I'm not quite sure what you're...

    Solving Trigonometric Equations

    What you have calculated here is the current at t = 1. Is the question not asking for the rate of change at t = 1?
