99-old-year mistake found in oxford dictionary

An eagle-eyed Australian scientist has forced the Oxford English Dictionary to change its definition of how a siphon works, after he found an error in the entry which had gone unnoticed for 99 years.

For almost a century, the dictionary incorrectly stated that atmospheric pressure, rather than gravity, is the operating force in a siphon, researchers said.

In 2010, Dr Stephen Hughes from the Queensland University of Technology spotted the mistake, which went unnoticed for 99 years.

For Exploring the boundary between the siphon and barometer in a hypobaric chamber, Hughes conducted an experiment in a hypobaric chamber.
