## Happy Pi Day 2015 – Celebrating 3.1415926

Pi day is celebrated each year on March 14th

This year I asked the question online who discovered pi and found there was no easy answer.  It has been an unfolding revelation through the ages as people have taken it to more and more places usually when they had nothing better to do and later letting computers do it for them.  If you want to read more about all that here is a wikipedia link to get started, but Archimedes is mentioned early on and Sir Isaac Newton also.  However, no one person seems to get the credit for the ‘discovery’.

The first recorded algorithm for rigorously calculating the value of π was a geometrical approach using polygons, devised around 250 BC by the Greek mathematician Archimedes.[30]

Isaac Newton used infinite series to compute π to 15 digits, later writing “I am ashamed to tell you to how many figures I carried these computations”.[52]

On Facebook, my friend Joseph Hebert pointed out that this is a very special year for pi day as you look at the opening digits you will see that we have a special instant.  Wonder if that is AM or PM?

“…But this time there will be a pi instant.

3.14.15 9:26:53.5897…

There will be an instant between 09:26:53 and 09:26:54 that will be the perfect pi moment.”

Have a pi moment today.  Have a piece of pie to celebrate.

Happy Pi Day!

## Happy Pi Day Everyone! Oh Sure It’s Not a National Holiday… Yet!

Happy Pi Day Everyone (3.14)    Get it?

Pi day is celebrated in math classrooms each year on March 14th

Pi Pics and Links from 2008

Here is how some math classes celebrate and don’t miss the pi song — it will hang in your brain for sure!  Students participated in special PI Day activities, celebrated the day by singing PI Day songs, and (of course) the traditional  eating of the pies.

Uploaded on Mar 27, 2010  This is a music video of the song “Mathematical Pi” by Ken Ferrier and Antoni Chan.

My First Pi day post from 2011 here >>>

At 3.14 (3 minutes 14 seconds) David Letterman learns what pi means! Daniel Tammet is an amazing math genius who memorised pi to 20,000 places. Is he the world’s greatest math prodigy? He is an amazing mathematics savant or maths prodigy.

Think I’ll go have another piece of pie now just to help celebrate the day.

## Mercedes Benz Ad Graphically Illustrates Left Brain – Right Brain Function While Questioning Are you Free?

Thanks to Linda Browning for posting the graphic and Amy Rice for sharing it with me!

My comment:

Everyone uses both sides of the brain; the question is when and how much and recognizing the need for both in ourselves and in each other. It graphically illustrates function while bringing us quickly to the question — Are you free?

Browning Studios: Art by Linda Meyer Browning
This illustration in a Mercedes Benz ad (of all things) really nailed the right-brain/ left-brain functions in this visually exciting illustration!

The ad copy reads:

(Left:) “I am the left brain. I am a scientist. A mathematician. I love the familiar. I categorize. I am accurate. Linear. Analytical. Strategic. I am practical. Always in control. A master of words and language. Realistic. I calculate equations and play with numbers. I am order. I am logic. I know exactly who I am.”

(Right:) “I am the right brain. I am creativity. A free spirit. I am passion. Yearning. Sensuality. I am the sound of roaring laughter. I am taste. The feeling of sand beneath bare feet. I am movement. Vivid colors. I am the urge to paint on an empty canvas. I am boundless imagination. Art. Poetry. I sense. I feel. I am everything I wanted to be.”

How much is the \$100 million dollars in budget cuts compared to the federal budget as a whole? This video imagines the budget as \$100 in pennies to provide the answer. For more on the budget, mathematics and political visualizations, follow the author of this video on Twitter: @PoliticalMath
