| Summary: | Look at what happens around us. A child that smiles, a nightingale that sings, aily that opens: all move. Every shadow, even an immobile one, is due to movingight. Every mountain is kept in place by moving electrons. Every star owes its formation and its shine to motion of matter and radiation. Also the darkness of the night sky** is due to motion: it results from the expansion of space. Finally, human creativityis due to the motion of molecules, ions and electrons in the brain. Is there a common language for these and all other observations of nature?Is there a unified and precise way to describe all motion? How? Is everything that moves, from people to planets,from light to empty space, made of the same constituents? What is the origin of motion? Answering these questions is the topic of the present text |
