Sun exerts much more gravitational force than earth;that's y earth revolves around it.Y doesn't then, the moon revolve around it 2? Y does the moon revolve around the earth?

gravitational force between them. Which means that any two objects in the universe pose forces on eachother. Just because the forces are neglegable doesn't mean they don't exist. Besides, Einsteins thoery of general relativity shows gravity bending space-time. Now the Q still stands: does the atoms mass produce the gravitational effect or does the gravitational effect produce the atoms mass?

I've heard of the two slot experiment.

My experience of this world leads me to have some sort of understanding waves (as on the sea) and of particles (smaller versions of something I can hold in my hand).

I am still having trouble, however, in how the two can be interchangeable or exist at the same time.

Refer to the ways of knowing: reason, perception, emotion and language. Does a machine have all that? Remember it's machine and not computer!!!
Also, refer to the areas of knowledge: ethics, the arts (music, literature), the naturals sciences (physics, chemistry, biology), the social sciences (geography, psychology, sociology, history), mathematics.
Can a machine know the knowledge found in these areas.

i really, really need an investigatory project in chemistry. as much as possible, an investigatory that is odd but not that complicated to apply in an experiment. please give me some proposal and it's procedure please. thanks alot.

The double-slit experiment explains the nature in which we've observed light acting as both particle and wave. By conventional science doing both simultaneously is impossible but that's exactly what happens. But really we all know we call particles of light photons and I'm aware that they are emitted from within the atom where a dissipation of energy can be observed without any fluctuations in mass. But my question still stands: where does it come from elctrons, protons, neutrons, quarks, neutrinos. And what exactly is a photon, when the double-slit experiment shows how a single photon shot through a single hole produces wave patterns on a second hole when the second hole is not the the trajectory of the fired photon. More weird is how the photon produces itself on a phtographic slate in its rightful position. First it's a particle, then a wave, and then a particle again. Apparently light doesn't follow the laws of conservation of mass and energy.

There are an awful lot of tiny atoms and each should fill up a finite volume of space. They are supposed to be travelling around the nucleus in a sort of perpetual motion.

Even with the electrostatic charges trying to separate them, shouldn't there be some collisions? What would happen if they do collide?

Is it a particle or a wave? Does it require a medium or is it one? Has anyone truly discovered the source of light? Or is it as fleeting as its velocity?

I searched on the web, and all I got are the usual components and what percent of air they make up. I'm more interested in how the components were discovered.
