Take the case of throwing a baseball. This is case 2 from parent
Assume that the magnitude of the drag on the ball is proportional to the square of its velocity. Also, assume that the magnitude of the gravitational force is constant. You get the following set of differential equations:
x''(t)*m=A * (x'(t)^2+y'(t)^2) * cos(theta) y''(t)*m=A * (x'(t)^2+y'(t)^2) * sin(theta) + g * m theta=arctan(y'(t)/x'(t))
Where: x(t) is the horizontal position of the ball at time t x'(t) is the horizontal velocity of the ball x''(t) is the acceleration y(t) is the vertical position of the ball (x'(t)^2+y'(t)^2) is the square of the velocity theta is the angle of travel above the horizontal m, A and g are constant over time*
* A=-1/2*drag coefficient*cross sectional area of ball*air density m is the mass of the ball g is acceleration due to gravity
The paper linked in the summary is essentially a rehash of this written in 2008: http://www.mat.unimi.it/users/carati/pdf/atenemissing.pdf This article essentially states that the far field gravitational effects of distant galaxies are not negligible. This is the essential meat of the idea.
From the article linked in the summary: "In the literature, there are several papers which illustrate different ways in which the distribution of matter can be estimated, starting for example from the measured distribution of luminosity of the galaxies. We take instead the simpler path which consists in assuming a functional form for [local gravitational potential], with a minimal number of parameters and then trying to determine these parameters by a best fit with the observed rotation curves."
This part really bugs me. Why does the author completely ignore the luminosity distribution of the test galaxies. At the very least this means that all the pretty graphs you see when scrolling through the pdf are misleading.
Thank you, we need more people like you in this country.
We need to stop using this "job creators" rhetoric that was handed down to us by some PR goons working on K street. The job creators are the same people who sit on there huge sums of capital and refuse to spend it. We should start using the term the job destroyers.
1. None of the employment problems that you mention occurred until Euro-zone trade liberalization moved jobs overseas. In other words the job loss was caused by free market policies not by socialism.
2. You did not account for the real unemployment rate witch under-reports employment in Europe and over-reports it in the us. The massive prison population alone in the us would account for a 2% increase in our unemployment rate if they were counted as unemployed.
http://www.csmonitor.com/Business/The-Entrepreneurial-Mind/2011/1109/The-real-unemployment-rate-and-Europe-s-underground-economy
3. You specifically neglected to mention countries where socialist protectionist policies cause unemployment to remain low like Norway.
4. Losing a job in any of those countries you mentioned is not nearly as bad as losing a job here because they have a functioning social contract. When you lose a job here you lose your health insurance. Also your comment specifically neglected to mention any of the other positive effects of socialism that I mentioned in my post.
5. The employment rate here is artificially low due to an excess of shitty part time and/or minimum wage jobs.
6. I think you meant I should stop smoking some elicit substance. When you say I should simply stop smoking that imply you are talking about smoking tobacco products which are usually not considered to impair mental ability.
The social contract we currently enjoy that has been slowly eroded for the past 40 years was a result of the New Deal.
The New Deal was spawned by the progressive movement during the 30s. The progressive movement was largely a reaction to prevent the revolution that occurred in Russia from occurring in the US. The revolutions that occurred in Russia was a direct result of labor organizing.
Regarding health care, were you aware that per capita health care costs in the US are almost double what they are in any other country. US government spending on health care is also the 2nd highest in the world per capita. So don't tell me that health care is what caused the economic problems of Europe.
Yes its true that the cause of the economic problems is funding of social programs with debt. The fact is that providing healthcare does not return a profit. The solution isn't to remove social programs, it is to increase taxes on the rich.
If we allow market forces to dictate all our economic policies there is a race to the bottom where workers earn sustenance wages. Your devotion to free market principles has taken on a religious zeal. If you want to see the end game of capitalism, move to Colombia. The way to fight market forces is protective tariffs, higher minimum wage, government job creation financed by higher top marginal tax rates, and a social safety net.
I say It should be. You might call me a whiner and complainer. I call myself someone with dignity and self respect.
This is why America is screwed. This country [usa] is filled with simpletons like parent that have no self respect. They say at least its not as bad as the third world shitholes. Well I say it could be a lot better too. We could have a country with universal healthcare, more vacation time, more job security and higher employment rate. This isn't some utopian ideal It happens in the socialist countries of Europe.
For Christ sake we put a man on the moon and the only point of pride you hear is: "[At least] I'm not melting solder off trashed PCBs in China."
The reason that your not melting solder in a shanty town is not because of the grace of the business elites allowed it to be so. It is because in the past labor organized and demanded better working conditions, weekends and an 8 hour work day.

What exactly is it that banks make? All I see banks doing is pushing little pieces of paper around and then patting themselves on the back as if they contributed to the economy. Cars, fuel, pens, and paper all have utility. Debt instruments provide no utility.
Something makes me think that as soon as they build a democratic, secular, and scientific society their democratic oil will be scientifically privatized to a secular corporation. The people of Libya will no longer get there welfare checks but they will enjoy a democratic, secular and scientific shanty town.

So far all the comments from the pro nuclear crowd have been something along these lines of:
Step1: Build safer reactor
Step2: ???
Step3: Profit
I used to be in-favor of nuclear power.
But seeing how big this screw up is I am not so sure.
here are some ideas that may help:
1:all current designs should be phased out in 5 to 10 years
2.All new plants should be lead cooled.
3.There should be no radioactive or toxic materials at high pressure.
4:All heat exchangers should be robust and the less radioactive side should be at higher pressure
5. use thorium
6. The backup scram system should be foolproof by using melt plugs. (If the reactor gets hot enough a structural component fails and inserts emergency control rods or perhaps the core structure melts and fuel components are no longer in a critical configuration.)
7. To dissipate heat from the delayed reaction after scramming, another melt plug is used that allows some of the coolant do drain onto an emergency heat exchanger attached to a pool of water outside. These two safety features are so robust the only way of sabotaging them is to go scuba diving in molten irradiated lead.
8.The entire contraption should be able to be transported on a barge to be encased in concrete and dumped in the middle of the pacific ocean if anything goes wrong.
I heard of this idea of attaching a unique hash value to each bill. This technology would use a suspended polymer with an affinity for cellulose. When applied to the bill this would allow unique tracking of the bill by altering its optical properties.
I don't see how this makes it any easier to track money than using ocr.

Why don't you move to India you fucking chump. You do have a stake in unions. The only reason you make what you do is because teachers and cops make 50k a year. In India software developers make 30k because they have no alternatives. No seriously: you and all your toothless redneck chump friends get the fuck out of my country.
The choice is not between BIG government and the patient/family. The choice is between government which is accountable to the voters and BIG medical insurance companies that are accountable to shareholders NOT THE PATIENT. There is a term for people like m0s3m8n. m0s3m8n is a chump. We in the US pay three times as much for health care than they do in France and yet we do not have any health care. Insurance companies only provide insurance to healthy people. And when you get sick they weasel out of payment due to pre-existing conditions. If you have any sort of chronic illness your only choice is to work for a company that provides health care. Apparently m0s3m8n thinks that McDonalds employees deserve to die. The problem stems from the belief that universal single payer health care requires everyone to live in the gulag in soviet Russia. m0s3m8n I hope you die of cancer

They should at least have a graph that shows the mass distribution from there model compared to a mass distribution from the luminosity distribution.
The paper linked in the summary is essentially a rehash of this written in 2008:
