I'm not sure if I want to do research or work in a hospital, as I am with the government right now. I just want to make sure I am in a growing career field that is not going to be overly saturated, but is still in need or demand, not too unlike the nursing and doctor shortage in the health sector.

Include 1 and integer as two of the factors.

This is not a homework problem. I just feel like giving 10 points to some deserving soul.

If it was possible to be at the precise centre of the earth, would you still be subject to a gravitational pull? Presumably you would not be weightless at that point? If there is a pull, what is it exerted by i.e. which part of the earth? So are you at that point being pulled outwards away from the centre of the earth? How do gravitons work?
Please ignore the problems of temperature and pressure at the core, I know in reality it's not survivable. Also I'm talking only about the earth's gravitational pull, not that of the sun or other bodies.
