Hi
I have recently been investigating an idea I had based around the phillosophical notion of order and the nature of time.
My starting point goes somewhere along the lines of:
If there are two particles in space. How does one particle know what the other has done until the light can...
Yeh that's great. Exactly what I was looking for :)
I will try and find Wheeler's book when I go back to uni! Really should remember all this stuff but sometimes it's quicker to ask.
Cheers

Hi
I am trying to write a code to find the minimum time until a sphere of expanding light interacts with a set of N particles moving at speed. These particles are acted on by forces which remain constant over the time period.
My problem at the moment is that these particles have a mass and...
Would I be right in saying a solid like your hand would be much more capable of transporting heat than air due to its higher density. Is this why you would increase the constant in the differential?
Of course the cup wouldn't attain the same equilibrium temperature as your hadns are warmer...
Thanks guys
Ill check out the site tommorow looks like ill have to do a bit more in depth reading onto all the different parrameters I've not really covered this stuff in my course yet but so far I see its just basic trig geometry.
Cheers

Hey
I am writing a basic javascript orrery which will display the position of the planets orbiting the sun. Using keplers equation I am going to find the true anomaly and the radius at the current time and then plot the points to a 2d grid.
The problem is I need to know the time that has...
Thats a superb shot considering the equipment. To image the planets though you really need a very large image scale. This means a smaller fov which is more easily obtained with cameras with smaller sensors like webcams. DSlr are more suited to widefield images. Also with a webcam you can employ...
Very wise words fra and I think I share a simmilar belief as you that we cannot objectively know something without introducing some kind of belief/probability.
What is an objective reproduceable experiment?
One in which the observers on average agree on the outcome of the experiment. With...
the way we got taught it is that the electron has a wavefunction which can give the position and a K space interpretation that gives the momentum using the de brogile idea of wave particle duality. These two properties the wavefunction and the K(wave number) function are interlinked by the...
Congratulations ;)
Im thinking youre probably at the same level of maths as me when it comes to this kind of thing. I am also in my first year doing an introduction to pure and applied maths.
Anyway if you have any more problems post em up then I can have a crack at em as I need the...
yes for this case we do not need to consider the z constant as it can be merged with the other constant u?
For the t=0 condition in your case you take t=0 when it starts to snow wheras I take it to be when the plow starts moving.This is why I added the factor d(0) it just depends on your...
Yes I agree the costs to oversees students are insane I think its about 10k a year. Of course we get our education for free north of the border so we just pay living costs. I am sure it would be cheaper for you to study in your home country. Though its deffinately worth checking for any...
I thought id have a go at it as I am doing an introduction to applied maths this semester.
I think its asking you to make a basic model of the situation.
If you say the speed of the plow dx/dt is inversely related to the depth of the snow D such that.
eq1. dx/dt = u/D
where u is a...
Yer that sounds like what we were doing.
Ah so the emission is more of a continuous spectrum is this built out of lots of separate pulses of differing wavelength?

Don't think so I am pretty sure all universities in Scotland work along the same lines. I didnt go to university to study stuff I don't want to or am not interested in. I have had enough of English and French at high school. The university of course has other subjects and is separated into 2...
