Pi Day is coming!

One of the tastiest ways to celebrate Pi Day!

March 14th (3/14) is also known as Pi Day, an annual celebration commemorating the mathematical constant π.  Officially recognized by the US House of Representatives in 2009, Pi Day was first celebrated on a large scale in 1988 at the San Francisco Exploratorium.  Pi is a symbol used to represent the ratio of the circumference of a circle to its diameter, which is approximately 3.14159. Pi Day is a great way to break out of the winter doldrums by having fun with math!

Fun Fact:  Did you know that Pi Day is also Albert Einstein‘s birthday?

Math has escaped the classroom!  Check out the Pi Sightings page to see Pi everywhere.

Parents:  There are many math activities that can be done at home, but in talking with students and parents, the favorite way to celebrate Pi Day at home is by bringing some pi(e) to the dinner table.   Chicken pot pie, shephards pie and of course, pizza pie are all great choices for a pi-themed meal.   There are even more choices to finish off your meal with, as pie is definitely a family-favorite dessert.  Check out this great list of ideas for other edible (and non-edible) ways to celebrate Pi.

Other fun ways to celebrate at home include taking a family walk, jog or bike ride for 3.14 miles.  NY Weather not cooperating?  Hop in the car for a short 3.14 mile drive.  Locally, The Rochester Museum and Science Center has special Pi Day activities from  3:14 – 6:28 pm on Friday.  If you can’t make it on Friday, they will have the same activities on Saturday and Sunday from 12-4.

Teachers:  Find grade-specific activities at Education World.  Want to include some Pi Day fun into your ELA classes?  Try writing a Pi-ku,  a math version of the traditional 5-7-5 syllabic haiku. A Pi-ku of course, follows a 3-1-4 syllabic pattern.

See this fun idea along with 4 others in the HOMEROOM (US Dept. of Ed blog).

A look ahead to next year: In the year 2015, Pi Day will have special significance on 3/14/15 at 9:26:53 a.m. and p.m., with the date and time representing the first 10 digits of pi.

Last 2 weeks for Math Midway!

Ride the square-wheeled tricycle in “Pedal on the Petals” and experience a surprisingly smooth ride.

If you haven’t checked out the new Math-related exhibit at the Rochester Museum and Science center, don’t let the opportunity pass you by. From carnival-inspired booths to brain-challenging activities, it all “adds up” to a load of fun!

The Math Midway exhibition celebrates the wonders of mathematics. More than 20 interactive, playful exhibits allow visitors to slip naturally into the world of pattern, shape and number.

The carnival theme adds to the fun and excitement of exploring this world. The Math Midway encourages direct physical investigation of the surprising breadth and variety of mathematics that can be experienced at many levels.  The age range is Pre-K and up.

See how mathematics can be an experimental science, how it can be a lens through which to view a situation, and perhaps most importantly, how math can be a fun activity accessible to everyone.

We checked out the exhibit this weekend during a Cub Scout overnight at the Museum, and it was a hit with kids and adults alike!

Famous Women in Mathematics

There is a very special relationship between one of my math professors this semester and a student in the class. The professor has said several times during the semester: “I need to find out about some female mathematicians”, usually after comments like: “…and that math book was written by a man, right?”  They have inspired me to do a little bit of research about famous women in mathematics to arm my professor with much needed information to respond to the student before this semester is over!

Hopefully this information will be useful to others to encourage young girls to pursue a career in mathematics or related fields.

I found three websites with lists of famous women mathematicians. Some of the links in the websites link you to biographical databases in other websites.  The three websites are: Biographies of Women in Mathematics, Famous Mathematicians from Underrepresented Groups, and Female Mathematicians. I checked all the mathematicians that were in more than one of the three lists and here are the ones I picked:

Name	Achievement
Theano c.16 Century B.C	Wife of Pythagoras. Ran School of Pythagoras after his death. Wrote works on the Golden Ratio.
Hypatia 370?-415	Made idea of conics easier to understand.
Florence Nightingale May 12, 1820 – August 13, 1910	Called: Prophetess of Applied Statistics Invented Polar Area Chart in the form of polar wedges to dramatize the needless deaths caused by unsanitary conditions and the need for reform.
Winifred Edgerton Merrill September 24, 1862 – September 6, 1951	First American woman to receive a PhD in math. Worked on the geometrical interpretation of multiple integrals and figure out the computation of the orbit of a comet.
Maria Gaetana Agnesi May 16, 1718 – January 9, 1799	“By far the most important and extraordinary figure in mathematics during the 18th century.” Most important work: Analytical Institutions gave a clear summary of the state of knowledge in mathematical analysis. It included: analysis of finite quantities; elementary problems of maxima, minima, tangents, and inflection points; analysis of infinitely small quantities; integral calculus; and the inverse method of tangents and differential equations.
Grace Chisholm Young March 15, 1868 – March 29, 1944	Worked with her husband on set theory. Authored 13 publications with her husband and 18 by herself. Bruckner and Thomson wrote that “The whole field of what was then called ‘the theory of functions of a real variable’ was reworked and rewritten in those first decades [of the 20th century]. The Youngs played a major role in that effort.”
Edith Clarke February 10, 1883 – October 29, 1959	Achievements in applications of mathematics to engineering. She became an authority on the manipulation of hyperbolic functions, equivalent circuits, and graphical analysis.
Irmgard Flugge-Lotz July 16, 1903 – May 22, 1974	Professor Flugge-Lotz acted in a central role in the development of the aircraft industry in the Western world. Her contributions spanned a lifetime during which she demonstrated, in a field dominated by men, the value and quality of a woman’s intuitive approach in searching for and discovering solutions to complex engineering problems.
Ellen Amanda Hayes September 23, 1851 – October 27, 1930	Hayes wrote several textbooks on Lessons on Higher Algebra (1891, revised 1894), Elementary Trigonometry (1896), and Calculus with Applications, An Introduction to the Mathematical Treatment of Science (1900).
Edna Kramer Lassar May 11, 1902 – July 9, 1984	Kramer’s greatest work is considered the book, The Nature and Growth of Modern Mathematics, which was published in 1970. This work took her 14 years to complete. In 1972 she was elected into the Hall of Fame at Hunter College. Her many books still are read and studied today, including A First Course in Educational Statistics, Mathematics Takes Wings: An Aviation Supplement to Secondary Mathematics, and The Main Stream of Mathematics.
Rózsa Péter February 17, 1905 – February 16, 1977	Péter was the author of Playing with Infinity: Mathematical Explorations and Excursions, translated into at least 14 languages, and Recursive Functions in Computer Theory. The latter was the second Hungarian mathematical book to be published in the Soviet Union because its subject matter was considered indispensable to the theory of computers.
Helena Rasiowa June 20, 1917 – August 9, 1994	Helena Rasiowa greatly contributed to the development of research in Poland on applications of logical methods in the foundations of computer science. She was one of the first to realize the great importance of mathematical logic for computer science – and at the same time she clearly saw the significance of computer science for the development of logic itself.
Argelia Velez-Rodriguez 1936-	Cuban Black Woman: First Black woman to receive a doctorate in mathematics at the University of Habana. She taught in several American schools before joining the mathematics faculty at Bishop College in Dallas, Texas, where she was chairperson of the Department of Mathematical Science from 1975 to 1978. In 1979 she became a program manager with the Minority Institutions Science Improvement Program in Washington, D.C. Since 1980 she has been a program director for the Department of Education.

As the author of Famous Mathematicians from Underrepresented Groups said: “… until recently, women were mostly prevented from doing mathematics, so relatively few women have become famous in mathematics.” Therefore, now that women are able to study mathematics, we must inspire, encourage and help girls become interested in mathematics at an early age and help them pursue careers in math or related fields.
