Science & Mathematics - 10 November 2007

Can anyone explain to me, in a physics standpoint, why there is not a falling sensation, similar to that felt on a roller coaster, when a jumper exits the plane just before terminal velocity is achieved? If at all possible I'm looking for a technical answer...college level physics answer.

How long does it take a baseball diamond (90 ft on a side) to receive 1 megaton of solar energy?

Neglecting energy absorbed or reflected by Earth's atmosphere, the solar energy hitting 1 square meter of Earth's surface is 1360 J/s (the solar constant). How long does it take a baseball diamond (90 ft on a side) to receive 1 megaton of solar energy? (Hint: A 1 megaton bomb produces about 4 x10^15 J.)

Why does the Bible keep on mentioning the light? Dirt(minerals) plus light(the sun) equals life right?

Doesen't energy(light) plus dirt equal us?Like when our energy leaves we turn into dust(or dirt). So we aren't just our physical brain we are also that energy because with out energy our vessel dies.

Just really think on this and then answer.

So in evolution where did the energy come from when the planet was all dirt before life started.

We had to come from dirt or some part of the planet.

When we eat the food transformes to our body.

Plants eat dirt , we eat plants so why coulden't a God make us from dirt with the breath of life(energy)?

Is it illegal to use a green laser for astronomy purposes?

I'm planning on buying a 5mw green laser pointer to mount on my telescope. Is it illegal to use it at night, just pointing at the sky (not waving it around, obviously) or is it fine with the law? Must I have legal, signed documents to use for astronomy or must I be a scientist conducting an experiment?

We are all parasites living on the same host?

This thought once came into my head while thinkning of all kinds of living things and how they feed..which is usually off other things. I even heard fleas can have fleas, and the fleas of fleas get fleas...plants can get parasites, people get parasites, we over abuse our host (pollution ect, we can kill the earth in a sense). Has anyone ever heard this our Earth is but one planet a host) and we are all just parasites living off this same host. I dont believe this but Im surprised I never heard such a staement from an atheist describing how we are not neccesarily "higher" than animals because we are more adept.
