Blueberry & Thyme Pie for Pi Day

http://prerelease.cookingstoned.tv/recipe/blueberry-thyme-pie-pi-day/

I’ve been wanting to make a Pi pie on Pi Day for some time. I know it’s a bit cliche but this Blueberry & Thyme pie is anything but. Sweet, tart and slightly savory, this is your next favorite pie! Happy 3/14! And by the way, extra points for a pie with 30 significant digits of Pi.            

“I have noted with great satisfaction that you always stand for the right and humaneness even when it is hard.” 

Letter, Albert Einstein to Eleanor Roosevelt, July 26, 1941. 
From FDR’s Papers as President: President’s Personal File 7177: Einstein, Albert. FDR Presidential Library. 

Eleanor Roosevelt’s efforts to aid Europe’s refugees began before the US entered World War II. She was seen by many as a trusted advocate who could bring their views to President Roosevelt’s attention. In July 1941, acclaimed physicist and German-Jewish immigrant Albert Einstein wrote this letter to Eleanor urging her to tell the President about the State Department’s rigid application of immigration rules and regulations. A “wall of bureaucratic measures” erected by the State Department, Einstein asserts, made it all but impossible to aid the victims of Nazi brutality. At the bottom of the letter in Eleanor Roosevelt’s handwriting are two notes. One says simply “FDR” and is an instruction to her secretary to send Einstein’s letter to the President. The second notation is Eleanor’s reply to Einstein which was later typed into a letter: “Tell Mr. Einstein I will bring his letter at once to the President.” Although Einstein’s letter was given to FDR, there is no evidence that the President responded to him or took any action based upon it.

Happy pi day! I talk about why Pi is awesome.

Love is like pi- natural ,irrational and very important.


What is Pi?

Pi is what you get when you divide the circumference of a circle with its diameter.

I have never truly understood where pi got its huge trailing numbers and what pi really means.

When I asked my high school teacher about it a few years back, this is what he rendered.


Carpentry

It goes back to the times when people ( probably Egyptians ) were trying to make wheels out of wood.

A wheel has two major components: The rim and its spokes.

                                                   Source

The spokes and the rim were made in separate sections. And later on, they were nailed together.

Awesome, right ? Not quite! Many a times the spokes and the rim did not fit in properly, and this led to lots of wastage.


The Birth of 22/7

There was a need to establish a standard in order to aid the making of the wheel.

After lots of trail and error, it was found out that if the ratio between the circumference of the wheel to the width/diameter of the wheel was 3, the errors somehow minimized.

Hmm.. How about we improve that..

And it is at this juncture that 22/7 was born.

You see 22/7 is ( 3 + 1/7th ) which was found to be a much better approximation than 3. Or an another way to think about it would be:

In order to make a wheel of circumference of 22 units, it needed a diameter of 7 units.


The Birth of Pi

From then on, people wanted to improve the approximation and that led to more and more refinements and finally we ended with this elegant number known as Pi.

Fascintating, isn’t it ?


Pardon me for any historical fallacies that this post might contain. History is not exactly my strong suit but if it is yours, then please do send in your feedback.

Have a HapPi day!
