- Statue of Isaac Newton at The British Library ... How does the amount of radiation change as the number of radioactive atoms decreases? How does speed change when a force is applied? The tool used to work these things out is called calculus.
Speed Of Light May Not Be Constant After All, Physicists Say

The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space. The definition of the speed of light has some broader ...Study of starling flight reveals message from turning bird sweeps through flock at constant speed

A team of researchers with members from several countries working together in Rome, Italy, has come up with a new explanation of how it is that starlings are able to fly in a flock in a way that makes them appear as a single organism. In their paper ...- The constant was first proposed by Edwin Hubble (whose name ... No matter where you are located in the cosmos, you would see the same phenomenon happening at the same speed. Hubble's initial calculations have been refined over the years, as more and ...
Constant Force and Constant Motion

I see this problem all the time. The idea that if you apply a constant force on an object, it should move at a constant speed. Really, this is what Aristotle would say, right? There are two course that have non-science majors: Physics for Education Majors ...
