Hi! Could anyone of you post here a link to a webpage that actually describes how a torque (of a screw) is transformed into a force that acts in the direction of the screw's axis, that makes is to screw in? Or could you briefly explain it? Any help would be highly appreciated.

Fact: Spacetime is a curved pseudo-Riemannian manifold with a metric of signature (-+++). Fact: A manifold is a set together with a topology that is locally homeomorphic to R^n. Question: In the case of space-time, what is the set, what is the topology and what is n?

Is there a link between the length of duration of El Nino and when the next El Nino event occurs.Also,what causes the sea to get so warm during an El Nino event - is the sea heated directly by the sun,does it get heat from circulating air,or does it get heat from currents of water bringing it...

Is there an intuitive explanation for the fact that in both relativity (time part of 4vector) and qm (frequency) energy is related to time and momentum to space? Thanks.

umm this question seems simple enough but I don't really know what I'm doing... A chain consisting of 5 links, each of mass .100 kg is lifted vertically upwards with a constant acceleration of 2.50 m/s^2. Calculate the force that link 2 exerts on link 1. so what I did was add the masses...

Gravity and the Casimir force are both attractive forces, and likely both follow energy conservation laws. Therefore it seems possible that the mysterious Gravity is nothing more than the Casimir effect at work between small fragments of matter. I wondered if this has already been...

Is there a link between physical and mental activity? For instance, when I'm feeling tired, often if I exercise, if I don't do it to strenuosly, afterwards I'll feel much more awake and alert. I would assume that since your heart gets pounding faster and your body sort of wakes up, that your...

Hey all, If you guys have some free time, perhaps you could take a look at this link. http://www.rebelscience.org/Crackpots/notorious.htm I'm pretty sure he's not correct, but I can't place the exact point in his thinking where it goes 'wrong', so to say. It just seems like he's saying...

Does anyone know some good links for A-level Physics Questions? Any help will be appreciated. Thanks in advanced.:smile:

Ok, here is the deal (you might laugh so hard that you hit your head in your screen;P) I had saved a link about particle physics from PF a while ago: http://www.kuro5hin.org/story/2002/5/1/3712/31700 My problem is that i can't remember if it was a good link or a paper that was debunked...

I thought this was an interesting idea, it's an animation of a theoretically habitable orbit around Sirius A. It's something *I* didn't expect. I always thought any planet pretty much anywhere in orbit of Sirius A would get baked by X-Rays from Sirius B every now and then. This site contends...

is there connection between breast cancer and abortions ?

I believe that calculators use Taylor expansions to compute sines, cosines and tan's based upon the argument \theta (in radians of course). However, my question is, aside from these expansions, is there some sort of link between \theta and the output of the function itself. I mean I know that...
