An Australian physicist spotted a 99-year-old mistake in the Oxford English Dictionary.

Dr. Stephen Hughes, from the University of Technology in Brisbane, was conducting research for an article for science teachers when he noticed an error in the dictionary for the word 'siphon'.The dictionary definition of the word stated that atmospheric pressure makes siphons work, when in fact it is the force of gravity. He said: "We would all have an issue if the dictionary defined a koala as a species of bear, or a rose as a tulip." A spokesman for the dictionary said the definition was written by "editors who were not scientists" and that Dr. Hughes's notes would be taken into account when the entry was rewritten.
