Larry Shaw, an Exploratorium employee, established it in 1988. Celebrations sometimes include eating pie or organizing pi **reciting contests**. The establishment of Pi Day was endorsed by the United States House of Representatives in 2009.

Shaw died on September 4, 2016 at the age of 70. He had been fighting cancer for several years.

The first annual 3.14 Festival was held in San Francisco's Mission District on March 14, 1988. It was created by Larry Shaw as a way to promote knowledge of mathematics through fun activities for children and adults. The festival continues today in **more than 20 countries** around the world.

In 1990, the second annual 3.14 Festival was held in Berkeley, California at the University of California, Berkeley. It was organized by UC Berkeley students who wanted to continue the promotion of math and science education after Shaw died. This year-long celebration includes lectures, workshops, and other events related to mathematics and science (some with **an educational purpose**, some not).

In 1999, the third annual 3.14 Festival was held in Boston's Downtown Crossing district. It was organized by **three women** who worked with Shaw during **his early years** at the Exploratorium: Candace Pedersen, Lynne Piddington, and Carol Shihade.

Larry Shaw arranged the first known official or large-scale Pi Day celebration in 1988 at **the San Francisco Exploratorium**, where Shaw worked as a physicist, with staff and the public parading around one of its circular areas and then enjoying fruit pies. The date was March 14, so it is now known as "Pi Day."

The idea for Pi Day began when Shaw was looking through old calendars and found that there were no exhibits at the Exploratorium during the summer months. So he decided to create one that would run from February 28 (just under three weeks after New Year's) to April 15 (just over three weeks before Memorial Day). He contacted the museum about holding a special event on March 14 and they agreed! Since then, other groups have started their own Pi Day celebrations. In 2004, Google made it an official holiday by adding a badge to **its search results** page to show when people can go to work or school.

In 2007, President George W. Bush signed a bill making March 14th **a national tribute** to the history of mathematics and science. The law states that this day will be called "Pi Day" and will be observed throughout **the United States**. It also encourages schools to hold events related to math and science every year on March 14th.

Since 2008, Apple has released a new operating system on Pi Day, which is when they release their new iPhone lineup.

The origins of "National Pi Day": On March 14, 2009, the United States House of Representatives approved a non-binding resolution (HRES 224), designating March 14 as National Pi Day. Larry Shaw invented the day in 1989. Originally, the holiday was observed in the San Francisco Exploratorium, where Shaw worked as a physicist. He invented March 14 because that was when the annual number of digits in pi is greatest.

After working at the Exploratorium for several years, Shaw decided to start his own company, which eventually became Shazam! Inc. After creating many other successful products, such as **Rock Band** and Dance Dance Revolution, Shazam! released **its first product** on March 14, 1999: the pi calculator. The company's motto is "Changing the Way People Think About Pi".

Today, most schools across the United States celebrate Pi Day with activities such as showing students how many digits are in pi, writing one thousandths (1/1000) of a mile on the ground with sand, or giving out prizes for finding a four-digit number that equals pi. Some companies also give out free samples of their products on this day.

Shaw sold **pi calculators** on March 14, 2009, and again two years later. The second sale took place on March 14, 2011. He raised $3,333 from **these sales** and gave all the money to charity.

It may be traced back to Larry Shaw, a physicist who is credited with organizing the inaugural Pi Day celebration in 1988. Some will undoubtedly be disappointed that the day has nothing to do with eating.

Shaw decided to start celebrating 3.14159.. Because it's such a nice number. He wrote a letter to science magazine Nature explaining his decision and asked scientists to help come up with an alternative date. The response was overwhelming, and today we have a holiday for everyone who enjoys mathematics and its applications!

In addition to being interesting numbers, pi and 3.14159.. Are also strange integers that can't be divided by **any smaller whole number** than themselves (except 1). This made them perfect candidates for use in celebrations. As far as we know, this is the only day of the year when people give gifts to each other over the internet instead of in person.

Although most people think of pi as a mathematical constant, it actually has many different definitions depending on how you measure lengths. There are several ways to define pi, but they all include three very large numbers: 4 billion, 91 million, and 150 thousand. These numbers are so huge that they can't be written down in a simple way, so experts use **special computers** to calculate them.

1988 What exactly is Pi (p) Day? Pi (p) Day, which began in 1988 at the Exploratorium, has grown into **a worldwide holiday** that is celebrated both live and online all over the world. The date (3/14) corresponds to the first three digits of the mathematical constant pi (p). March 14 was chosen because it is an odd number, so there would be no confusion as to whether you are adding or subtracting periods from March.

Pi Day was created by **computer scientist David J. Malan** who also founded the annual International Pi Conference. He wanted a single day to celebrate all things pi and since **March 14th** had the least conflicts with any other holidays, he decided this would be the best day to have a celebration.

Malan started the tradition by sending out an email to colleagues announcing the creation of Pi Day and its corresponding URL. Within a few days, many other scientists had joined in the fun by creating their own events on March 14th.

Today, people celebrate **Pi Day** in schools, universities, museums, and science centers throughout the world. Festivities often include presentations about pi and related topics along with prizes for the best costumes (usually related to math or science).

In 2014, more than 20,000 events were held in 180 countries with participants coming from **every country** on Earth! It's a great way to get kids interested in math and science while having some fun on March 14th.
