century medical scientists made a surprising discovery: that we are built not just of flesh and blood but also of time. They were able to demonstrate that we all have an internal "body clock" which regulates the rise and fall of our body energies‚ making us different from one day to the next. The idea of an internal "body clock" should not be surprising‚ since the lives of most living things are dominated by the 24-hour night-and-day cycle. The most obvious feature of this cycle is the way we feel tired

Clocking the Speed of Light Why is the speed of light important? -Having a accurate number for the speed of light allows for accurate measurements of the universe around us -Even small inaccuracies make large differences when measuring the space between stars‚ planets‚ and galaxies -The more precise our measurement of the speed of light the more precise our measurements are of the universe because light is the universal measurement used Light as Infinite -Most scholars agreed that light
