Science in Ancient Egypt
Nilometer on Elephantine Island (Nile Valley Tours)
Egyptian scientists were generally most interested in observing nature and practical engineering, and they were very good at both of these things. The pyramids and temples, for example, show good knowledge of geometry and engineering. Egyptian engineers used the Pythagorean theorem, thousands of years before Pythagoras was born.
Because the Nile flood was so important to Egyptian farming, scientists also worked out good ways to measure how high the flood was going each year, and kept accurate records and good calendars. You can see here how the Egyptian wrote down numbers. The device they used to measure the height of the Nile flood is called a Nilometer (ny-LA-muh-terr).
Egyptian doctors were also considered the best in the ancient Mediterranean. They figured out how to set broken bones, pull out infected teeth, and massage aching muscles. They did a lot of early research into how the human body worked.
It may also have been Egyptian scientists who first figured out how to make wheat and barley into beer and yeast-rising bread. By the time of the Ptolemies, Egyptian scientists worked out ways to hatch goose and chicken eggs in giant factory incubators to make roast chicken cheaper.
