Mathematical Masterpieces has 345 pages for four independent chapters, each a story anchored around a masterpiece of mathematical achievement.
The chapters are ( with between brackets the OU course they relate to )
1. The Bridge Between Continuous and Discrete ( MS221 ) - This chapter is about the Discrete Calculus and explains calculating sums using the Pascal Triangle.
2. Solving Equations Numerically ( M373 )
3. Curvature and the Notion of Space ( None, don't know )
4. Patterns in Prime Numbers: The Quadratic Reciprocity Law ( M381-N )
The book is intended for advanced undergraduates who know at least a year of calculus and have some maturity with mathematics at the upper-division level.
I am currently reading ( studying ) chapter 4. ( The chapters can be read in any order ).
