"a man who figured out how to have his pi and recite it, too - beyond 60,000 decimals. All it took was intensive practice and a knack for storytelling, a new study finds."
Pi Cubed is a visual math application for the iPhone / iPod touch that lets you perform calculations as you would on a piece of paper. By using an animated, touch-based interface, even the most complex mathematical expressions can be entered and instantly evaluated. These expressions are typeset as they would be in a textbook or on a blackboard. Calculations are displayed with up to 34 digits of decimal precision. Additionally, a library of over 150 equations ships with the application.
"An average person can read out approximately 120 digits/min. Keeping this pace it would take more than 158,000 years to recite the 10 trillion digits of π discovered this year and roughly 3 weeks to read out the 4 million digits visualized here."
Beyond simple math and grouping (like "(x+2)(x-4)"), there are some functions you can use as well. Look below to see them all. They are mostly standard functions written as you might expect. You can also use "pi" and "e" as their respective constants.
"there are plenty of other infinite decimal (and infinitely useful) numbers to celebrate-Feb. 7 could have been e Day, for example, or Jan. 6, the Day of the Golden Ratio."
abstract: "A large number of studies carried out on pupils aged 8-14 have shown
that teachable agent (TA) based games are beneficial for learning. The present pi-
oneering study aimed to initiate research looking at whether TA based games can
be used as far down as preschool age. Around the age of four, theory of mind
(ToM) is under development and it is not unlikely that a fully developed ToM is
necessary to benefit from a TA's socially engaging characteristics. 10 preschool
children participated in an experiment of playing a mathematics game. The partic-
ipants playing a TA-version of the game engaged socially with the TA and were
not disturbed by his presence. Thus, this study unveil exciting possibilities for
further research of the hypothesised educational benefits in store for preschoolers
with regard to play-and-learn games employing TAs."
"It is the age-old question every student asks: "When will I ever use this math in real life?" While it may seem that long division and pi are not applicable to life outside of the classroom, visitors to "MathAlive!" will learn exactly the opposite-math is actually a big part of all the things they love" Includes a description of exhibits for the Smithsonian event beginning March 10
