Q Branch celebrates Pi Approximation Day!

Felix Leiter’s Bourbon Chocolate Pecan Pie

filling:

3 large eggs

3/4 cup (150g) dark brown sugar, packed like a body in an oil drum

2/3 cup (200g) light corn syrup or Lyle’s golden syrup, Your Snootiness *cough* James

1 teaspoon vanilla extract

1/2 teaspoon salt

2 tablespoons (30g) melted butter, (Live a little, salted or unsalted)

2 tablespoons bourbon

1 2/3 cups (190g) pecans, I use halves (use toasted and very coarsely chopped, if you’re an overachiever)

3/4 cup (120g) chocolate chips, I use semisweet chunks, but smaller would meld better.

Make or procure a crust and put it in a 9 inch (23 cm) pie plate and crimp the edges as you do.

Preheat the oven to 375ºF (190ºC) and position the oven rack in the center of the oven. Remember to take out anything you’re storing in there.

In a large bowl, whisk together the eggs, brown sugar, syrup, vanilla, salt, melted butter, and bourbon. Whisk it well, but not so well you have to repaint the kitchen ceiling again, Alec.

Stir in the pecans and the chocolate chips. Scrape the filling into the pie shell with a rubber spatula, not your hand, Alec.

And bake for 30 to 35 minutes, or until the filling puffs up slightly but still feels slightly jiggly and moist in the center. Let the pie cool completely before butchering it, you impatient bastards.

Serve with ice cream or whipped cream and the rest of the bottle of bourbon..

Pi Approximation Day, July 22

Pi or pie, whether you’re a baker or a math whiz, today is your day.

Pi Approximation Day – July 22, 2022

Pi or pie, whether you’re a baker or a math whiz, today is your day — Pi Approximation Day on July 22 honors the concept of pi, which is denoted by the Greek letter pi and approximates to 3.14, in the most mathematically-pleasing way. To further make punny jokes out of pi day, many bake pies on the holiday. It’s a great day to appreciate the math concept used so regularly in many calculations, and eat some delicious pie!

History of Pi Approximation Day Pi has been known for nearly 4000 years in some form or another. Ancient Babylonians used it — approximated to 3.125, to calculate the dimensions of circles. It was around 250 B.C. that pi was first calculated by one of the greatest ancient mathematicians, Archimedes of Syracuse. He found that pi fell somewhere between 3 1/7 and 3 10/71. Pi is occasionally referred to as the ‘Archimedes’ Constant.’Later, in the mid-400s, another brilliant mathematician, Zu Chongzhi, computed pi again with lengthy calculations. Since Archimedes’ books were lost, and not in China at that time, Zu calculated pi himself in a novel way. Between Zu and Archimedes, these two scientists were the first to know pi in any true sense.Later, mathematicians attempted to better approximate pi using circumscribed and inscribed polygons. This was how Archimedes first solved for pi, and it remained the dominant algorithm for pi computation for 1,000 years. The most correct approximation achieved using this method came in 1630, with Austrian astronomer Christoph Grienberger, who arrived at 38 correct digits of pi.With the development of the infinite series (the sum of the terms of an infinite sequence) in the 16th- and 17th centuries, the way pi was calculated was revolutionized. In India, they discovered it early, between 1400 and 1500 A.D., yet it’s European mathematicians like Leibniz and Gregory who popularized it a century later. Though pi was a well-known concept for centuries, it wasn’t until 1706 that the Greek symbol pi came to represent it. This was suggested by William Jones, a Welsh mathematician, but not popularized until it was used by Leonhard Euler in 1737.In modern times, endless amounts of computing power have been dedicated to approximating the infinite, irrational number to the fullest extent possible. The first time pi was computed by a machine was in 1957, when George Reitwiesner and John von Neumann used an ENIAC computer to compute 2,037 digits of pi. Many intrepid mathematicians followed. By 1973, a million digits were reached with this method.The calculation of pi became a useful stress test for a computer’s abilities — almost like a test for the heart. Mathematicians also hoped to have more accurate calculations for pi for cosmology, though, for most pursuits, few digits are needed. Emma Haruka Iwao, a Google employee who calculated more digits of pi than anyone else to this point — 31 trillion, has earned a place in the Guinness Book of World Records.

Have you ever heard of a girl group called 22/7? They have their own anime and rhythm game, and their latest album reached #2 on the charts here in Japan. Because of the date, I’d like to dedicate today’s mission to them… but there’s something else.

Back on March 14, I neglected to even mention that it was Pi Day. I know how much you love holidays based on irrational numbers, so allow me to make it up to you. Much like 3.14, another way to approximate pi is with the fraction 22/7. Well, what do you know? That’s today! Go get ‘em.

YO, your birthday is on Pi Day!!! Happy Birthday, I hope you have some good pie.

Lolol I was waiting for someone to bring that up! Yes, I am blessed to be born on a day where it’s completely acceptable to eat copious amounts of PIE <33

Fun fact: I was born on Pi Day, and my husband was born on Pi Approximation Day (July 22nd, or 22/7) which is celebrated over the pond since the US is one of the only weirdos who writes their dates the way we do. Long story short- it was destiny ;)
