1 Lessons from the History of Mathematics
Tom Osler Rowan University

2 Is Mathematics a Humanity or a Science?
Humanities The branch of learning regarded as having primarily a cultural character and use, including languages, literature, history and philosophy. Sciences A branch of study that is concerned with observation and classification of facts, and especially with the establishment or strictly the quantitative formulation of verifiable general laws by induction and by hypothesis,

3 The 5 minute history of math
There were only two principle explosions of mathematical creativity Greek 600 BC to 200 AD European to today

4 The 5 minute history of math
Today math research is performed all over the world by both men and women This was not true only 40 years ago, when most researchers were men with names of European descent Note: Until 1800, mathematicians were known as “Geometers”, not mathematicians

5 The fragility of mathematics
Few cultures nourished math Most people born with math gift never had a chance to develop it

6 Math is unlike any other academic study
Does not change Euclid’s Elements No errors for 2300 years God is a Mathematician

7

8 The mother of mathematics is astronomy/astrology
Babylonian planet and star charts Greek Astronomy Eratosthenes BC measures earth diameter (error 5%) Hipparchus BC distance to moon (error 5%) and to sun (error 2000 %)

9 Lesson 4 The mother of mathematics is astronomy/astrology
Motion of Sun, Moon, Planets and Stars Develop Calendar of Seasons Month – Lunar cycle Year – Solar cycle Predict future events – Astrology Positions of Sun, Moon and Planets on the Ecliptic Zodiac

10 Apollonius 256-190 BC invents epicyclic motion
Ptolemy – Almagest 150 AD Earliest trig tables Predicts planet positions with an accuracy one degree in 100 years

11 The mother of mathematics is astronomy/astrology
Navigation Need to find longitude after 1500 Newton ( ) Invents calculus Law of gravity Universal Laws of motion Nearly every great name in math from Kepler (1600) to Gauss (1850) worked on Celestial Mechanics Poincare and Chaos

12 The wheel in Mathematics is the decimal number system
If the Greeks had known it, they would have understood irrationals Possibly they would have invented algebra and analysis

13 A second wheel is shorthand math symbolism
Before 1500, most problems in math were expressed by rhetorical language and not letters and symbols as we do in algebra. “The square of the unknown added to twice the unknown plus 4 vanishes”

14 Lesson 7: Euclidean Geometry retarded Math development for almost 2000 years
Today it is dead Even Newton wrote his principia in geometric language, and not with the calculus he invented
