Hi Sari!
Well I kind of was in the same position (but not really..)
Anyway I was originally at uni a long time ago, then a bundle of joy decided to bless me with their presence. My partner was out of work, and I was at uni, so I decided to leave and join the army to provide for my new family...
So as the object approached the black hole, it would slow down. Would an observer actually see the object 'go into' the black hole? It seems to me the object would appear to be stationary at the event horizon to an external observer; whereas the object would actually be 'in' the black hole. Is...
Ah darn it yes that was a stupid mistake! Should have been 0.2. And I've just realized I don't need the entire equation as dg/dr will be multiplied by 0, just like you've said. Thanks for that!
Homework Statement
Manufacturing plants create rolls of metal of a desired gauge (thickness)
by feeding the metal through very large rollers. The thickness, g (mm),
of the resulting metal depends on the gap, r (mm), between the working
rollers, the speed, s (m/s), at which the rollers turn...
Oh good so I was right, thanks. So should I integrate with rho being between 0 and 2a, with phi being between pi/2 and pi/3, and then...well I get stuck there. I've got that little cone bit in the middle to go and I don't know how to get him (or her). Sorry I'm just not getting this one
Homework Statement
Use a triple integral to calculate the volume of the solid enclosed by the sphere
x^2 + y^2 + z^2=4a^2 and the planes z=0 and z=a
Homework Equations
Transform to spherical coordinates (including the Jacobian)
The Attempt at a Solution
I'm stuck, as the radius...
If people didn't need it, it would be a novelty. I'd open up 'Sleep parks' and would charge heaps to give people the new experience of sleep.

Orion by metallica, gives me goosebumps and takes me away!

Hi Marcus,
Thanks for the link! I think I may have posted prematurely without doing more research into it myself! But it's good to know a great deal of others are uneasy about the singularity (theory). Guess I was duped by reading too many popular science books!
Thanks again.

Hi,
I was just pondering the moment of the Big Bang, and have been doing some reading on the subject, in which there exists problems consolidating the mathematics of relativity and quantum mechanics. To my understanding the theory of realtivity predicts the universe started from the Big Bang...
Hmmm well I think that the whole premise of relationships is based upon possession and what the other person can do for you. It even makes itself present in language; ie MY[B] husband [B]MY wife. Women are attracted to men who can provide for them, which in some cases means sacrifices. Of course...
Ah good example RoughRoad! Indeed Ramanujan had almost no formal trainng in maths, and was taken to Cambridge I think, and he soon died because it was said he just couldn't fit into his new life (died of malnutrition and other things I think). So the prestige school and surrounding actually...
