Vectors, by Gordon Lawrie

If you can recall your school mathematics lessons, ‘vectors’ are distances to which direction has been applied. Their practical use really only dates from the mid-eighteenth century, but they’re known as ‘Euclidean’ vectors because it was the ancient Greek mathematician Euclid who first spotted their importance. 55 more words
