Lol, probably a lot more than you'd get out of it, I should imagine! Which is why I keep Charlie as my pet, instead of using him to power the world. Noble as that would be, of course. :P Thanks for your reply my friend.

Hi all, I've been teaching myself about energy unit conversions (because I never paid attention at school) and just wondered if someone could check my math please? It's not a homework question - I've not been to school for 10 years! Just a curiosity on my part... I was trying to work out...

Yeah, I meant that, but I phrased it wrong ;) So essentially, all the energy we 'loaded' the object with in accelerating it close to c will come back to bite whatever object gets in its way ;) An object in a classical universe traveling at .9c would have required less energy to get there...

So could it be said that, since it requires increasingly large amounts of energy to accelerate an object towards C, it would also require increasingly large amounts of energy to decelerate an object that was traveling close to C?

I've not got much of a background in physics, but this question has bugged me for ages. So I hope you don't mind me asking :) I know that as an object under acceleration approaches the speed of light, it becomes increasingly more difficult to push it further. I imagine it like pushing against...

Hi Stephen and Diffy, Apologies for the late response, I was on holiday. To answer Stephen's questions: When you press the 'Slowdown' button, the game will set its target slowdown rate (say a rate of 50% normal game time) and a controller gradually increases the length of each frame to achieve...

Hi all, I'd appreciate a little help here. I'm making a video game, and one of the features is the ability to slow down time - a kind of Matrix-esque Bullet Time effect. I know there's a computing section, and a physics section, but I felt the issue is primarily mathematical, which is why...

I was wondering; Imagine two situations: 1) I rotate an axle with a strong magnet attached within a conductive coil (a dynamo). 2) I rotate an axle with a strong magnet attached without a conductive coil. Does the presence of a coil (and therefore the generation of current in the coil)...

So taking into account the refractive index of any transparent container it would require, would it be possible to create a lens with a specific refractive index simply by creating a shaped container of pressurised gas/liquid? Just curiosity really :) Like with water, if it were possible...

I have a question! On my desk is a aerosol of compressed air, for blowing dust away and stuff. If you look carefully, the jet stream of air causes a visible refraction against the background. Why is this? I'm assuming it's based on the same way that a heat-haze causes refractions over...

One thing I've found after looking into dcalc and dlex is they are very individual problems, unique to each sufferer. It's a little like the common cold, just as two people with a cold can actually have very different virusses causing the symptoms, two people with dyslexia could be manifesting...

By functionally illiterate, do you mean someone who can't read? I know it sounds like a stupid question, but sometimes people use 'illiterate' to mean people who aren't able to do a wide range of stuff (i.e. computer illiterate, number illiterate, etc). There are some examples of both, for...

I've been given a problem by a chap on another forum, to do with making a computer game. The guy wants a missile pre-aim system (a little like clay pigeon shooting), where the target's angle in degrees and speed in pixels-per-frame are used in conjunction with the missile's own speed to...

I work outside, and have absolutely no circulation in my hands. And I like hair-brained schemes. So with these things in mind, I thought I might have a crack at making a little rechargeable pocket heater. Unfortunately, I know very very little about actual electrics. But hey, that's what...

How does that work? I suppose I'm thinking of it in terms of a bullet, an object going that fast would be pretty hazardous. And I suppose a bigger bullet at the same speed would obviously carry more energy. So is it the case that photons are just stupidly small, and the more you have the...
