Happy Pi Day! Pi shows up a lot in geometry, but if someone thinks pi only has to do with circles, then they are missing so much of the mystery of pi. For example, take the odd integers: 1, 3, 5, 7, and so on. Now take their reciprocals: 1, 1/3, 1/5, 1/7, and so on. Now alternate subtracting and adding these: 1  1/3 + 1/5  1/7 +, and so on. This sum approaches pi/4. Here's another example, take the integers: 1, 2, 3, 4,... Now take the squares of their reciprocals: 1, (1/2)^{2}, (1/3)^{2}, (1/4)^{2},... Now add these: 1 + (1/2)^{2} + (1/3)^{2} + (1/4)^{2},... This sum approaches pi^{2}/6.
Even Google gets into the spirit. 



The NJSLAM will take place sometime between April 8 and May 28. The Algebra 1 exam will be divided into two units each 90 minutes long. NJSLAM High School Student Tutorial 

March is the month in which the mathematician Paul Erdös (March 26, 1913) was born. He was born in Hungary. Erdös (pronounced "Airdish") posed and solved problems in number theory and other areas of mathematics. He traveled the globe constantly never owning a home and living out of a suitcase. About a month out of every year, he lived right here in Watchung at the home of Ron Graham another famous mathematician. Erdös referred to children as "epsilons" the fifth letter of the Greek alphabet.  
March is also the month in which the mathematician Emmy Noether (March 23, 1882) was born. She was born in Germany. Noether (pronounced like "mother") made many contributions to mathematics in particular abstract algebra. She came to the United States in the 1930's and taught at Bryn Mawr College outside of Philadelphia.  
March is also the month in which the mathematician Caroline Herschel (March 16, 1750) was born. She was born in Germany. She lived a Cinderella life as a house servant until her mathematical abilities were noticed. Working with her brother, William, she discovered nebula and comets. Her brother discovered the planet Uranus.  
In 1994, Roger Schlafly a mathematician from California obtained a patent for two prime numbers. Schlafly actually opposes the idea of patents for software and obtained the patent to point out what he believed to be deficiencies in the U.S. patent system. Prime numbers are used in cryptographic software. Here is the smaller of his two patented primes: 7,994,412,097,716,110,548,127,211,733,331,600,522,933, 776,757,046,707,649,963,673,962,686,200,838,432,950,239, 103,981,070,728,369,599,816,314,646,482,720,706,826,018, 360,181,196,843,154,224,748,382,211,019
