Thanks guys; atyy, that was exactly what I needed.

Are complex cells in the brain physically different from simple cells or is the difference in their function/role?

I shall now quote page 304 of 'The Emperor's New Mind' by 'Roger Penrose' (1999 publication), he is commenting on the double slit experiment: Individual particles DO act in accordance with the probabilities of interference, which is one of the key aspects of the quantum world.

I worked out the tension in a pendulum string to be T = mgcos theta + mv^2 / r where r is the length of the string, m is the mass of the bob, v is the bob's velocity, g is acceleration due to gravity and theta is measured from the vertical. I got this equation from the forces acting on the...

Check out this YouTube video, I watched it only yesterday and I think it'll answer your question. It's 50 minutes, but well worth it!

I'm making a pendulum simulation, so far everything works! I have a free moving pendulum following simple harmonic motion that hangs from a point. My problem is that I would like the pendulum to act appropriately when the point it hangs from is moved (in x and/or y directions). To do this, my...

Hey guys, I've nearly finished a little project I've been working on over the last few days. Take a look at these simulations: 1 Joint Springs 2 Joint Springs In both simulations you begin with an initial joint, press and hold to create new joints. You can also drag joints and, by pressing 1...

Thanks for the reply, berkeman. This is for a personal project. I'm actually trying to get some fundamentals down before I attempt to create some frameworks; I played World of Goo recently and wondered whether I could produce some similar, although simpler, structures.Thinking about it, would...

Hi all, Okay, so the problem. Say we have a bar fixed to a horizontal surface by a hinge, at the end of the bar is a weight, which is fixed so that it cannot move. The bar is lifted to some angle \theta and let go of. I'm ignoring air resistance and the weight of the bar. I'm trying to...

I'm trying to create a simulation of some frameworks. For my situation, these are light (I'm ignoring their weight) rods connected by joints. Currently, the joints do not hinge or otherwise move and can have a weight, effectively a force applied to the point. Oh, and I'm also ignoring air...
