I think we'll have to agree to disagree.

Nah, gravity acts instantly. The centripetal acceleration of Jupiter is towards the solar system barycentre, as it is, and not where it was fifty odd minutes ago. The infamous space time rubber sheet presupposes what it claims to explain. I totally fail to understand this obsession with the...

Cheers Liber :thumbup:

Liber very kindly took a model I'd made of James Bond's car and did some magic with it to reduce its poly count. Now I've not the slightest idea how to put this thing up in the addons. So if anyone wants to have it, then I'm sure Liber will explain all the arcane stuff that I'm a total idiot with.

Note the mention of the aether. Then we have the mention of Lorentz and Poincare, there should also be a mention of Riemann. This period, of a major crisis in physics, is popularly called the aether wars. It didn't end an outright victory for Einstein's relativity but as something akin to the...

There's always this footage which shows astronauts making their own 2001 flywheel. Another little oddity is zero g cookery :) It seems that a low rev rotating oven is best for roasting stuff. The sunday joint doesn't cook properly unless you can give the air a little g .

The principle moment of the rocket would change, or then again perhaps not :lol:

I'll have to have a bit play with that, bear in mind that I'm pretty thick :huh: A few words on the "superlens," create a grid of nano wires which have a negative permeability. Then nano split rings, tank circuits in effect, which have a negative permittivity. (On first reading about this, I...

Hi Jarvita, how do you get square roots and stuff to appear on the board?

I don't know but I don't think so. Let's write the Lorentzian in terms of refractive index sqrt(1 - 1 / eta) Now we can construct negative refractive index materials. Interesting little aside here. A few years ago I looked the "superlens" and read a very clear and simple account of how it...

Being an absurd optimist, I think the light barrier will be cracked, I'd even put money on it but the bookies would write in so many caveats. In another thread i did mention that gravity acts instantaneously, and waited fro the howls of protest. it was this problem that kept Newton awake at...

Partial joy maybe.

Maths is a meta language.Metalanguage - Wikipedia, the free encyclopedia. Music is a meta language, as is cinema. I can recall sitting in a college bar and everyone was moving paper napkins into folds to look at the topology of jokes. I think this teacher has a rather limited idea of what...

I've had a look at the db5 and it's got way too many polys I think. I think I'll redo the tyres and see what can be trimmed off it.

Here's a scenario for a game within a game. I've tried this out with a few people who I consider to be very intelligent. The results were rather surprising. Scenario:-A couple of geniuses and their friends have built an ftl probe, moreover they have placed one end of a wormhole onto the probe...
