In 1704, Newton proposed a different take -- one describing light as corpuscles, or particles. After all, light travels in straight lines and bounces off a mirror much like a ball bouncing off a wall. No one had actually seen particles of light, but even now, it's easy to explain ...
Newton reasoned that the moon might be under the influence of Earth's gravity, as well, but he had to explain why the moon didn't fall into Earth. Unlike the falling apple, it moved parallel to Earth's surface. What if, he wondered, the moon moved about Earth in the same way as ...
You probably think ofGalileo Galileiat the mention of Renaissance science, and rightfully so. He overturned Aristotle's ideas on motion and began to explain such complex concepts as force, inertia and acceleration. He built one of the firsttelescopesand used it to study the cosmos. What he sa...
Refractionoccurs when a ray of light passes from one transparent medium (air, let's say) to a second transparent medium (water). When this happens, light changes speed and the light ray bends, either toward or away from what we call thenormal line, an imaginary straight line that runs pe...
It is important to realize that Einstein does not explain what happens at the 'radius of the universe' that causes an expanding spherical surface to begin to contract (because he did not know!). The solution is now solved using Huygens' principle as we have previously described. Thus; ...
"The colors of a rainbow so pretty in the sky. Are also on the faces of people going by." -Louis Armstrong It's no secret that white light is the light that we see when all the colors shine together and are seen at once. This has been known for over 400
