what do scientific people believe about god? do they believe that there is something divine about this universe and ones beyond? or do they believe that if you cant prove it, its just not a fact? is everything just coincidence and happenstance, or are some there things that you cannot scientifically explain away and must be done by some higher power?

A new test is developed to test for a certain disease, giving "positive" or "negative" results to indicate that the person does or does not have the disease. For a person who actually has the disease, the test will give a positive result with probability 0.95. For a person who does not have the disease, the test will give a positive result with probability 0.05. Furthermore, only one person in 1000 actually has the disease. If a randomly selected person is given the test and tests positive, what is the probability that the person actually has the disease?

I read today that NASA is getting ready to send more people into space, but the article didn't elaborate a reason why. This seems to be the case quite a bit in my experience. Am I just not reading the right sources that can detail a reason, or are the reasons for space travel being kept under wraps?

in a strictly Newtonian system:

if GMM/d^2 gives the force of attraction between two sperical planetary masses (of homogenous density) the size and mass of the sun Ms, ether

prove,using integration or whatever, that the formula gives the force of attraction EXACTLY EVEN WHEN the two planets' surfaces are less than 1 inch apart
(i.e. regarding the masses as large spherical gas clouds almost touching each other)
OR
calculate the % difference in terms of their masses between the actual force of attraction and the force of attraction as approximated by GMM/d^2
when the two planets' surfaces are less than 1 inch apart.

if your answer contains the double integral of:

[density(r1)]. [density(r2)]. [dV1]. [ dV2] ... / (r1-r2)^2

explain how this can be integrated.

We have a relatively new microwave. I was reheating some ground hamburger for my dog on a microwave-safe plate in the microwave. I was watching it spin around for the 10 secs, and noticed 2 tiny "sparks" coming from the meat. Does this mean the meat is contaminated with metal? I couldn't find any pieces. Or is this normal? (I've heated meat before, but never really took notice) I'm worried about the rest of the meat in the refrigerator as well as the microwave. Thanks.
