Greek Mathematicians Quotes & Sayings

Greek mathematics is the real thing. The Greeks first spoke a language which modern mathematicians can understand ... So Greek mathematics is 'permanent', more permanent even than Greek literature. — G.H. Hardy

Anywhere - and, it follows, nowhere - can be a place. As long as we are there, to think and talk, to listen and respond. The world, once conscious of itself in the form of human making, is a vast concert hall. What sounds there is not the divine music of celestial spheres, as the ancient Greek mathematicians believed, but the sound of one human after another issuing the daily plea: to be heard, to be understood, to be accommodated. — Mark Kingwell

The ancient Greek mathematician Ptolemy was born some time at the end of the first century. Ptolemy based his version of trigonometry on the relationships between the chords of circles and the corresponding central angles of those chords. Ptolemy came up with a theorem involving four-sided figures that you can construct with the chords. In the meantime, mathematicians in India decided to use the measure of half a chord and half the angle to try to figure out these relationships. Drawing a radius from the center of a circle through the middle of a chord (halving it) forms a right angle, which is important in the definitions of the trig functions. These half-measures were the beginning of the sine function in trigonometry. In fact, the word sine actually comes from the Hindu name jiva. — Mary Jane Sterling
