Pi Day & Einstein's Birthday 3/14

In honor of Pi and Albert Einstein (who was born on March 14th ), I've included some sites provided by the Annenberg site.

Pi Day (March 14)
Pi Day is observed in the U.S. on March 14 -- 3/14 -- in recognition of the value of pi. Celebrations can begin at approximately 1:59 p.m. as a further reminder of pi's approximate value, 3.14159.

With "Learning Math: Measurement"

Session 7, "Circles and Pi," investigate the irrational number pi and its relationship to the circumference and area of a circle.

Watch "The Brain: Teaching Modules"
http://learner.org/redirect/march/brain47.html
Program 20, "A Super-Memorist Advises on Study Strategies." This short clip features Rajan Mahadevan, who has memorized the first 99,000 decimal places of pi and, amazingly, can jump in and continue from any point within that
set of digits!

"Math in Daily Life"

In particular, watch Program 25, "Kepler to Einstein," and Program 43, "Velocity and Time."

Middle school teachers and students can explore central ideas in physics with "Science in Focus: Force and Motion" http://learner.org/redirect/march/force51.html and "Science in Focus:
Energy" http://learner.org/redirect/march/energy52.html
