Warning: This is a potentially stupid question! Is it possible to induce photosynthesis with laser light? What kind of published work is there on it? Thanks!

That's interesting, I did not know that. What book/text would you recommend for me to understand photon behavior more completely? Yes! Problem solved!

Slaughterhouse-Five was awesome.

So EM waves have their own set of laws that have nothing to do with classical physics right?

btw, I want to preface this with "I don't know" I'm just trying to figure this out. That makes sense that it would not need a continual force to maintain it's velocity, but what initially forced the wave to that velocity? Because light shows signs of particle-wave duality, wouldn't the...

I would agree that you are exerting a force, because you are accelerating the ball at 9.8m/s^2 in the opposite direction from the center of the gravitational field. However mathematically, Work is defined by Force x Displacement, there is no displacement. So no work is being done.

I've been thinking about some really elementary ideas of light and I just can't get a handle on this. Everything on the electromagnetic spectrum travels at 3.0 x 10^8 m/s, but what force is exerted on these waves to travel at this speed and wouldn't Newton's third law mean that there would...
