My grounding in the field is shaky, but by my understanding of "Schrodinger's Cat" is that nothing exists except as a cloud of probabilities until it is observed. Then, wouldn't the existence of the universe imply that there was some original observer that predated the cosmos. Who's observation collapsed the probability fields and caused the cosmos to actually exist?
I can see soo many ways that I am wrong with this, I would appreciate someone knowledgable's input.

What i want to know deals with light, NOT how to mix paint to get brown or about making chocolate icing. every half intelligent scientist knows that colors are really what light wavelengths an object does not absorb. Black absorbs all, and white none. but what about brown??

I hear that they are building a nuclear fission reactor in France. The benefits to our society would be immence, but if it backfires could it possibly destroy our exhistance?
I mean if it works we WILL have discovered a endless fuel source and our reaches will be greater than ever.
But technically couldn't it implode on itself destroying the facility and possibly the world?

A look at the surface of the sun in Ultraviolet reveals a complexity that many people believe could support a computational engine several orders of magnitude more powerful than the human brain.

This implies other sentient stars, and my personal belief is that our sun has a bet with his star buddies on who can create the doofiest life form.

If that is true, and if we are it, IS HE WINNING?

A fish has a length of 1.5 m and a mass of 63 kg.
It accelerates from 3.0 m/s to 6.3 m/s.
Assume there is no drag force.
F is exerted until 2/3 of the fish's length has left the water.
What is the magnitude of F? In Newtons (N)?

This trick is hard to get right, but it works - you just have to know the sound of the ping. It works with any can of soda etc...

I am a college student and have a reasonably good grasp on physics. A book with a little bit of mathematics behind the theory is preferrable.

I know the Handgun (Revolver) Colt Python has a huger .357magnum Caliber and the same company is doing Pistols almost no damege compred to the huge damage coursed by one shot from a Colt Python with standerd rounds, why cant they combine the benifits of a Pistol with the pershot damage power of the .357magnum Colt Python? Are they not intrestrested in perfection? or they like to mess with us? and if not why is it?

does anyone know of attempted proofs of time's lack of continuity? i'm looking for names and links specifically. i'm not interested in the approach from a philisophical perspective, rather from a mathematical one. i understand that "i doesn't matter because we can't perceive the intervals" or whatever one may say. thanks though.

A Chinook salmon has a maximum underwater speed of 3.0 m/s, and can jump out of the water vertically with a speed of 6.3 m/s. A record salmon has a length of 1.5 m and a mass of 63 kg. When swimming upward at constant speed, and neglecting buoyancy, the fish experiences three forces: an upward force F exerted by the tail fin, the downward drag force of the water, and the downward force of gravity. As the fish leaves the surface of the water, however, it experiences a net upward force causing it to accelerate from 3.0 m/s to 6.3 m/s. Assuming that the drag force disappears as soon as the head of the fish breaks the surface and that F is exerted until 2/3 of the fish's length has left the water, determine the magnitude of F.

two fishes "A" whose mass is 5kg and "B" whose mass is 7.5kg, collide while swimming in opposite directions. Their speeds are A=2m/s and B=0.5m/s. After the completely inelastic collision, what are their speeds? What equations would be used to figure this question out?
