Today's Quotation
It is true that I should have been surprised in the past to learn that Professor Hardy had joined the Oxford Group. But one could not say the adverse chance was 1:10. Mathematics is a dangerous profession; an appreciable proportion of us go mad, and then this particular event would be quite likely.

This is the title page of Johannes Kepler’s Astronomia Nova published in Linz in 1609. In translation its full title reads “New Astronomy based upon Causes or Celestial Physics". Further clarification is also added, “Treated by means of commentaries on the Motion of the Star Mar, from observations of Tycho Brahe, Gent.” Thus using Tycho Brahe’s data, Kepler focused work on the orbit of Mars. His ten year investigation led him to conclude that the orbit of Mars was not a circle but another conic section, an ellipse. In this book he substantiates and formulates two of his laws: 1. Planets orbit the sun on elliptical paths. 2. The sun serves as one focus of these ellipses. | |

"In these numbers we use no fractions": A Classroom Module on Stevin's Decimal NumbersAfter completing this assignment on Simon Stevin's treatment of decimal fractions in his 1585 De Thiende, the author's preservice mathematics teachers understood why our usual procedure for multiplying such fractions works. |
The Classic Greek Ladder and Newton's MethodGreek ladders for approximating square roots may be more ancient than the ancient Greeks. Students at any level can appreciate their beauty and simplicity. Those who have studied calculus can compare them with Newton's Method for approximating roots. |
