Pi Day
Pi Day is on March 14, and any day that combines fun, education, and pie is a day worth celebrating! Pi, also known by the Greek letter “π,” is a constant value used in math that represents the ratio of a circumference of a circle to its diameter, which is just about 3.14….15…9265359… (and so on). Not only that, but the fourteenth of March is also Albert Einstein’s birthday, so all together it’s nothing short of a mathematician’s delight.
History of Pi Day
To learn about pi, we need to go back a few thousand years and learn about this elusive number. The value of pi was first calculated by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
However, it was first baptized with the Greek letter as its name when William Oughtred called it as such in his works dating back to 1647, later embraced by the scientific community when Leonhard Euler used the symbol in 1737.
But how did Pi Day end up in a country-wide phenomenon? For that, we need to travel to the Exploratorium in 1988 San Francisco, where it was thought up by physicist Larry Shaw.
Shaw linked March 14 with the first digits of pi (3.14) in order to organize a special day to bond the Exploratorium staff together, where he offered fruit pies and tea to everyone starting at 1:59 pm, the following three digits of the value. A few years later, after Larry’s daughter, Sara, remarked that the special date was also the birthday of Albert Einstein, they started celebrating the life of the world-famous scientist.
Pi Day became an annual Exploratorium tradition that still goes on today, and it didn’t take long for the idea to grow exponentially, hitting a peak on March 12, 2009, when the U.S Congress declared it a national holiday.
Now, celebrated by math geeks all around the circumference of the world, Pi Day became a pop culture phenomenon, with several places partaking in the activities, antics, observations and all the pie eating they can.

Traditions of the day
Pi Day gives math enthusiasts the opportunity to celebrate their love for numbers and the enigma that is the infinite pi.
Since 1988, the day has been celebrated at the San Francisco Exploratorium. The first celebration was organized by Larry Shaw, who worked as a physicist at the center. The staff participated by marching around the exploratorium and consuming fruit pies. This tradition has lived on since. Math lovers talk about math, host get-togethers, and have pi recital competitions. In schools, teachers arrange scavenger hunts, pie bake sales, and even Pi Day workouts to stimulate more interest in learning and practicing mathematics. Those folks who work in food marketing also love to get involved, so keep your eyes peeled for some discounts, deals, and freebies on pies, it’s going to be an extra tasty day.

Pi Day FAQs
Why is pi important?
Pi is very important for calculations in math, engineering, construction, physics and space exploration. Many often consider pi the most important number in all of mathematics.
Which pie should I bake for Pi Day?
Any you’d like. We do not play favorites when pie is concerned. Pies are really simple to make and can be made with several sweet or savory fillings. Apple Pie, Chicken Pot Pie, Pizza pie, be our guest!
Are there any places that give Pi Day deals?
Check restaurants, supermarkets and bakeries over on the Internet for special Pi Day deals. Places like Whole Foods, Boston Market and several pizza chains across the country have special day-long sales.
Pi Day Activities
- Enjoy pie of course: Pi is a homophone of pie: the 2 words are pronounced similarly, but are spelled differently and mean different things. Celebrate Pi Day by eating lots of pie! Pizza, cherry, apple, you name it!
- Throw a potluck party: Everyone loves to show off their family pie recipe. Make it a potluck and everyone will be inclined to bring their favorite pie to Pi Day, whether it’s a pizza pie, a pot pie, a savory pie, or a sweet pie. Make a playlist that features songs like “I Like Pie, I Like Cake” and “American Pie.”
- Try making a new pie: Ever tried to make a pie before? Now’s your chance to bake your very own. Not into the sweet stuff? Don’t worry, there are various savory pie recipes out there so that everyone can enjoy the warm buttery flakiness that comes with a fresh baked pie.
5 Facts About Pi
- People compete in memorizing it: Rajveer Meena has the record for memorizing the most decimal places of pi at 70,000.
- It’s used as stress tests for computers: Computing pi is a kind of “digital cardiogram” for computers.
- A Givenchy men’s cologne is named pi: So you can smell like pi too if you are the intellectual and visionary kind.
- It has other names: Pi can also be named “Archimedes’ constant,” or “Ludolph’s number.
- It has been used by heroes: Spock foils the evil computer by having it calculate pi’s value in Star Trek’s episode “Wolf in the Fold”
Why We Love Pi Day
- Pi is infinitely cool: Pi (π) is the ratio of a circle’s circumference to its diameter — and amazingly for all circles of any size, pi will always be the same. Pi is an "irrational number,” meaning its exact value is completely unknown. Scientists have calculated billions of digits starting with 3.14159265358979323…, but no recognizable pattern ever emerges. We could continue on and on until infinity and we’d still have no idea what digit might emerge next.
- Pi sounds like pie: If you are a nerd that likes pies this holiday is pretty much the best combination of the most interesting things in life: pie and mathematics. And of course that means that in order to celebrate abstract mathematical items that are somewhat irrational the obvious solution is to incorporate pie into the holiday.
- Pi links mathematics to the real world: Maybe when you were in math class, you stared off into space wondering why on earth ‘logs’ or 'proofs’ mattered so much. Pi is the answer, well at least, one of the things that links math back to real world uses. Because pi is linked to circles it is also linked to cycles, things like calculating waves, ebb and flow, the oceans tides, electromagnetic waves and much more. In addition, many natural world phenomena can also be calculated with pi — like the shape of rivers, the disc of the sun, the spiral of DNA and even the pupil of an eye.

Austrialia Furnance - Article 1
Australia Furnance - Located in Alleghany, VA (County)
Listing date on the VLR: 03/17/1999
The Australia Furnace was important during the iron industry in the 19th century. The Australia Furnace is tied to the nerby Lucy Selina Furnace. E & B.J. Jorfan and Co. stopped using the Lucy Selina Furnace in order to construct a more modern furnace. They built the Australia Furnace in the 1850’s. It was bigger and able to accommodate a hotter temp.
Though it is no longer standing, it still features the process of iron processing. Located on the Simpson Creek near Lucy Selina, the Tredger Iron Works in Richmond supplied the furnace. J.R. Anderson of Tredger bought the furnace during the Civil War. Soon, the operations were ruined due to the difficult transfer of materials. Longdale Iron Co. bought where both Australia and Lucy Selina were located. They removed the Australia to establish a mining hamilt but Lucy Selina is in operation.

Lozärner Fasnacht Recap
The Lucerne Carnival is the largest annual occasion of the city of Lucerne and also of Central Switzerland. In addition to the Basel Carnival, the Rabadan in Bellinzona and the Bärner Fasnacht, it is one of the carnival strongholds of Switzerland. The visitor record in 2025 was 350'000 participants. This makes the Lucerne Carnival the largest carnival in Switzerland.
The carnival event focuses on the old town on both sides of the Reuss and the Neustadt. The Lozärner Fasnachtskomitee (Lucerne Carnival Committee), LFK for short, consisting of the Safranzunft (guild of saffron), the Wey Zunft (Wey guild), Fidelitas Lucernensis and the Maskenliebhabergesellschaft (mask lover society of the city of Lucerne) and die Vereinigte (the United) Guuggenmusigen (umbrella association of Lucerne Guuggenmusige) are responsible for organizing the major events.
Sadly, it’s already over. Four days of fun, loud music and rain. I can’t remember the last time we had such bad weather during carnival: four days of carnival and four days of rain (and wind). So there were fewer people at the Fasnacht than in the last years.
I’m still tired, I went to bed this morning at 5.30 a.m. As I already told you: it’s the best carnival in the world. It’s free and for everyone. Just make sure you’ll wear some kind of a costume. The most part of the Lozärner Fasnacht takes place outside in the Old Town.
The costumes and grende (big masks of the Guuggemusig - like a marching brass band) and the floats are handmade. Every year the costumes, grende and floats changes. The most Guuggemusig players aren’t musicians. They only play their instrument in the band.
The next one is going to start on 4 February 2027. Way to early in the year for me. I prefer later dates.
