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 ...What is the Boltzmann Constant?

The Stefan-Boltzmann constant (?), ties the amount of energy radiated by a black body (per unit of area of its surface) to the blackbody temperature (this is the Stefan-Boltzmann law). ? is made up of other constants: pi, a couple of integers, the speed of ...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 ...- 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.
