@DanielSank I can at least count in a close enough approximation, so am willing to haggle... But yeah, they put the prices of everything up for foreigners :/
"Abstract: We prove, once and for all, that people who don't use superspace are really out of it. This includes QCDers, who always either wave their hands or gamble with lettuce (Monte Zuma calculations). Besides, all nonsupersymmetric theories have divergences which lead to problems with things like renormalons, instantons, anomalons, and other phenomenons. Also, they can't hide from gravity forever."
Can a gravitational field possess momentum? A gravitational wave can certainly possess momentum just like a light wave has momentum, but we generally think of a gravitational field as a static object, like an electrostatic field.
"You have to understand that compared to other professions such as programming or engineering, ethical standards in academia are in the gutter. I have worked with many different kinds of people in my life, in the U.S. and in Japan. I have only encountered one group more corrupt than academic scientists: the mafia members who ran Las Vegas hotels where I used to install computer equipment. "
so Ive got a small bottle that I filled up with salt. I put it on the scale and it's mass is 83g. I've also got a jup of water that has 500g of water. I put the bottle in the jug and it sank to the bottom. I have to figure out how much salt to take out of the bottle such that the weight force of the bottle equals the buoyancy force.
For the buoyancy do I: density of water * volume of water displaced * gravity acceleration?
so: mass of bottle * gravity = volume of water displaced * density of water * gravity?
@EmilioPisanty The measurement operators than I suggested in the comments of the post are fine but I additionally would like to control the width of the Poisson Distribution (much like we can do for the normal distribution using variance). Do you know that this can be achieved while still maintaining the completeness condition $$\int A^{\dagger}_{C}A_CdC = 1$$?
Fairly straightforward... but solving SHM questions via energy analysis is new to me. Now I'll upload a picture (it's on the variation of gravitational acceleration with depth, on earth)
Now the question I have combines SHM and gravitation..
(I'd like you to have a look at the proof, and see if the final relation in the picture is okay)
@Alan Well your equation $g(x) = g(1-x/R)$ becomes $g(r) = -gr/R$. The minus sign is because we measure $r$ outwards while the acceleration is inwards i.e. in the opposite direction.

@JohnRennie Hmm, okay, I'm looking forward to that :-)
@JohnRennie Before you showed me how to do it, I was under the impression that energy analysis was quickest way to get Things done XD
^ for classical mechanics
I'm still shocked it didn't work out as well/neatly as I hoped
@JohnRennie If I have questions like these again, will I still be able to ask you? (Judging from the chat transcript, everyone's bombarding you with questions, so it might be a bother) O:)
You're always welcome to ask. One of the reasons I hang around in the chat room is because I'm happy to answer this sort of question. Obviously I'm sometimes busy doing other stuff, but if I have the spare time I'm always happy to answer.
Though as it happens I have to go now - lunch time! :-)
@JohnRennie It's possible to do it using the energy method. Just we need to carefully write down the potential function which is $U(r)=\frac{1}{2}\frac{mg}{R}r^2$ with zero point at the center of the earth.

Also I don't particularly like this SHM problem because it causes a lot of misconceptions. The motion is SHM only under particular conditions :P
I see with concern the close queue has not shrunk considerably in the last week and is still at 73 items. This may be an effect of increased traffic but not increased reviewing or something else, I'm not sure
Not sure about that, but the converse is certainly false :P
Derrida has received a lot of criticism from the experts on the fields he tried to comment on
I personally do not know much about postmodernist philosophy, so I shall not comment on it myself
I do have strong affirmative opinions on textual interpretation, made disjoint from authoritorial intent, however, which is a central part of Deconstruction theory. But I think that dates back to Heidegger.
I can see why a man of that generation would be leaned towards that idea. I do too.
doing some kind of measure theory stuff in maths chat. Currently trying to prove the rationals are of Lebesgue measure zero by using an uncountable cover jut for the sake of completeness of proof
Can anyone remember that cool integral where the first 15 values are the same, and then suddenly the next value is many orders different? It's something like nested sine functions.
