Silence Please
If there is one group of workers across the Western world who will be glad that Christmas is over, that group is shop workers.

That thing is music. These days, all shops and many offices have what is known as "Piped music" or "muzak" playing for all the hours that they are open. Muzak has an odd history.

[填空题]In addition to his theory of colour, Newton developed a theory of how light travels. This is known as the corpuscular (微粒子的) theory of light, meaning that light travels as a series of tiny bits rather than of continuing waves. Newton sent his writings about light to the Royal society, where they were given to a committee led by Hooke. Since the corpuscular theory was different from his own theory, Hooke attacked the paper.
