OK /sci/, I am filling out a job application form and am posed with this question:
What investments could (company) make to maximise its market position while maintaining a responsible risk profile? (the company specialises in commodity trading)
can /sci/ recommend any answers, or anywhere I can look to help me to answer this question well. I am obviously looking for a low risk, large profit investment, but don't know enough about this area to answer this question well.
background: I am a Maths/Stats grad applying for a trainee trading position and want to answer this question as well as possible, but have no experience in this area.

WHY DOES HOT AIR RISE?

This is another question that is answered by current science, but answered very incompletely.
>According to statistical mechanics, where air has greater kinetic energy it has a greater probability to occupy a higher gravitational potential than less energetic air. That is, the system tends toward maximal entropy.
The statistics are based on observation, and explaining gravity with entropy is a dodge. We don't want an airy statistical mechanics, we want an old-fashioned mechanics that is capable of showing a physical mechanism. Once again, this question cannot be answered with current theory, which is why the internet and textbooks are full of bad answers. We need the charge field of the Earth to answer it. The charge field is an emission field of real photons, and their (summed) direction is straight up from the surface of the Earth, radially out from the center. This explains rising heat very quickly and simply because we now have a way to bring density into the gravity equations, with simple mechanics. A gas that expands into greater volume will cover more area and encounter a larger section of the charge field. So it will encounter a larger force up, and will rise.
This simple mechanism also explains another mystery. It has never been understood how a gas maintains its energy, despite a colossal number of collisions. In a real gas, as opposed to an ideal gas, the collisions cannot be completely elastic. Energy must be lost over time to collision. But gasses have a way of maintaining energy, as if they had a constant source of propellant. They lose neither energy nor velocity, at least not to any extent we expect they would. Well, it turns out they do have a source of propellant, and that source is the charge field of the Earth.
