You live in portsmouth, near the coast, salt in the air+aluminium, with its top layer of Al2O3 removed by a scratch=corrosion. End of.

It sounds really gay but I'm shitting it because tomorrow i have my higher physics exam and I'm confident ill pass but I'm top of my year and have got 100% or close to it in two or three practice past papers and all the teacher expect me to do it now, which is allot of pressure. And i know I'm a nerd so please don't hurt me for it.
Don't worry about it, it's a fairly easy exam I found, advanced is even easier. Oh and how did it go?

Looks to me that is should *just* clear, good idea Edward.

Snappel is right, SIA security guards aren't supposed to carry anything above a 4D, but I prefer not to carry a mag lite at all when I work, find it provokes more than it intimidates.
As for torches a lot of the guys at work use one version or another of this they're f**king bright, enough to stun and dazzle anyone, and pretty well focused too.
-
If you're going to buy a maglite get a C cell, you get a much nicer swinging action on them.

Use a thinner lighter chain if you want, but keep an eye on it.

I'm pretty sure someone will be along to correct this, but I think that trespassing is NOT an arrest-able offence; they can only ask you to leave. However, if you BREAK in, then you can be done for criminal damage. Or something.
Well, actually there is one sort of trespass that is indictable, aggravated trespass, if you go somewhere and make shed loads of noise etc you should be fine, just leave when you're asked, you're fine. However in Scotland there are no real trespass laws.

Sorry to be a pedant, but the brake mounts will only be half an inch out, 20" and 19" are the diameters, not the radii. So you could probably make an adapter to run it for the time being..

I often dont poo for 5 days, 3 days is the norm for me though, I dont see why your so desperate to poo it out?
Because that's your normal rhythm, it's what you're used to, Dave is used to shitting more often, so for him that's uber uncomfortable.

anthrax comes from the middle east
cocaine comes from south america and if 2.3kg of cocaine turned up on my doorstep in exchange for £25 I wouldn't be complaining
You'd complain if it turned up with a bunch of policemen.

Nah, try apple juice and/or massaging your stomach and kidney area.

So it actually happened in Poland? God I love this country, it pwns everything and everybody. I'm not that surprised really, every time I return from the UK and drive into Poland, I'm shocked at how bad the roads/drivers are here. And I mean shocked. It's supposed to change in the next few years hopefully. Couldn't care less about a twat having an accident but if he killed other people, he deserves to be dead.
You think Poland is bad?
You should see the Ukraine. -
If you're making a frame and are having trouble with clearance just use an 85 or 100mm bottom bracket shell.

That's basically what I said, although I must admit, I had not seen the (1/(1-(v/c)^2)^0.5) part of the equation before.
F=GmM/r^2
The Sun and the solar system as a whole has a gravitational effect at a further distance although yes, outside the immediate vicinity there is little effect although this will still act on the ship.
Anti matter does exist, it's very hard to make, it's almost impossible to contain and it's very, VERY explosive. The thing is, the mass of the ship would have to be large for the force of the stars and planets top become noticeable, this is why it's called microgravity, cos it's at a microscopic level.

I asked "Where is David Simon Wilhelm Spain, what does he do and what else can you tell me about him?"
Reply: David Simon Wilhelm Spain is one of 25 UK adults named David Spain. One of them went to university in Preston and lives in Highbury and works in music.
Well, reassuring to know they can't find out anything about me.

Yeah, but thin oil will not interfere with the engagement AT ALL, it's too thin to do so, so there's no point in not running it.

I woke up for no reason at around 0830 yeaterdat, I'm blaming the quake.

They cannot reach the speed of light.
Especially in a large spaceship. Remember E=mc^2, energy has mass, and if you want to get to the speed of light you'd need to have infinite mass which is impossible.
The closer you get to the speed of light the heavier the ship is and the harder it is to get any faster (as it requires more energy to push the extra mass faster and then this energy also needs more energy to make it go faster etc etc etc etc).
Once you've put a relatively small distance (relative to the solar system, we're talking 0.01 lightyears here) between the ship and the solar system you are far enough away that it's gravity has very little affect on the ship and it is basically completely free from any force. From there on you can just "coast" along.
To be honest the gravitational forces from the solar system won't affect a ship much at any point in it's journey....
E=mc^2 is the equation for rest mass energy, once you start moving the equation become E= (1/(1-(v/c)^2)^0.5)mc^2, the faster you got the more your mass would increase, so more energy would be needed, so more mass etc in vicious circle.
Oh and by the way, once one has left the immediate vicinity of a planet one is barely affected by the gravitational attractions as the force obeys an inverse square law.
How are you going to give an entire spaceship negative mass?Maybe you can make little things with "negative mass" (not heard of those theories, always thought negative mass is impossible, as if it did exist it would suck everything in and destroy the universe (like that weird particle made in the LINAC on the End of Days Panarama documentary)) go faster than the speed of light but a big spaceship is never going to be able to go faster than light, or anywhere close.
I'm not getting carried away, it's proven fact.
Why would you need a wind tunnel for something traveling in a vacuum?
Testing could be done on a computer though, you wouldn't have to put it straight on the ship, or use up any materials on prototypes. The brainy inbreds could write programs for testing all sorts of components haha.
I have no idea about the affect of inbreeding but I'm fairly sure a ship landing on a new planet ought to be full of genetic diversity otherwise any martian virus could wipe them all out veeeeeeeeerrrrrrrrry easily.
We could beam there star trek style haha Although it'd take all the energy of the Sun to achieve it. Basically matter is converted to energy then you send it shooting off across the Universe where you reform as energy. Only problem is, other stars are light years away, so would you age as energy? And what would happen if most of your energy is absorbed in the planet's atmosphere?
This subject is far too complicated haha
For something to have negative mass it has to be antimatter, which annihilates on contact with matter, for example humans, in an explosive manner.

Either thin grease or thickish oil for lube, if you're not confident removing bearings etc from hub shells go see your LBS, if you are the technical drawings on the hope website should do the trick.

Looks like it should be good, I hope they have beefed up the front end for any heavy impacts from dirt jumps.

OK, it's not a complete waste of time because it's kinda interesting. But I don't think it's testing the right thing.
Sweat is a great lubricant. The point of chalk is to keep your hands dry, right? Water is NOT the same composition as sweat - sweat is much, much greasier. I don't care if sweat is 99% water, that extra 1% obviously makes a lot of difference.
Also, subjectively, I climb a lot and my sweaty hands hold me back a lot - and chalk definitely helps. There is no doubt at all.
I have some liquid chalk anyway - which doesn't even leave any dust on your fingers. Best of both worlds?
How do you find the liquid chalk, thinking of buying some to try...

Hmm, I'm sceptical, how the fudge can they determine the planet's surface gravity?? Which btw () "is probably around twice that of the Earth and the atmosphere could be similar to ours."
That's why I linked the News24 article, they don't publish quite so much tripe!
The roughly know the mass, and they know the radius, so using: E=GM/R^2 one can calculate the value of th gravity, simple really.
If there is life on that planet, they'll be roughly twice as strong as us.

Welcome back man, good to hear your starting up again. Will bashguard.com be getting an update then?

Yeah, but it could look like rust depending what forms, and it would have the same weakening effects, rust is just a name for corrosion of Iron by oxygen.
