physicsphysics: The following concerns a question in a physics degree exam at the University of Copenhagen: Describe how to determine the height of a skyscraper with a barometer. One student replied: You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will...

It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level. The holograms you find on credit cards and banknotes are etched on...
