Pi Day 2014
March 14, 2014 in the World

Pi Day and Pi Approximation Day are two unofficial holidays held to celebrate the mathematical constant p (pi). Pi Day is celebrated on March 14, or in the month/day date format as 3/14; since 3, 1 and 4 are the three most significant digits of pi. March 14 is also the birthday of Albert Einstein so the two events are sometimes celebrated together. Pi Approximation Day is held on July 22, or in the more common day/month date format as 22/7, which is an approximate value of pi.

Pi Day is observed on March 14, because of the Ancient Greek mathematician Archimedes’ first rough approximation of pi as being 3.14. (A few years later, Archimedes was able to calculate a much better approximation of pi.) However, 22/7 is actually a closer approximation of pi than 3.14 is. Thus, a more “accurate” Pi Day could be found in the more common calendar, 22/7, or July 22.

Sometimes the so-called Pi Minute is also commemorated. This one occurs twice on March 14 at 1:59 a.m., and 1:59 p.m. If pi is truncated to seven decimal places, it becomes 3.1415926, making the Pi Second occur on March 14 at 1:59:26 a.m. (or 1:59:26 p.m.). If a 24-hour clock is used, the Pi Second occurs just once yearly, on March 14 (3/14) at 1:59:26 in the morning.

There is a large variety of ways of celebrating Pi Day and most of them include eating pie and discussing the relevance of pi. Pi Day is often celebrated with pies, given that pi and pie are homophones. The first Pi Day celebration was held at the San Francisco Exploratorium in 1988, with staff and public marching around one of its circular spaces, then consuming fruit pies. The museum has since added pizza to its Pi Day menu. The founder of Pi Day was Larry Shaw, a now-retired physicist at the Exploratorium who still helps out with the celebrations.

Fun fact – MIT (Massachusetts Institute of Technology) has often mailed its application decision letters to prospective college students for delivery on Pi Day! Starting in 2012, MIT has posted its application decisions on a private website on Pi Day, exactly at 6:28 pm. They have deemed this “Tau Time”, in honor of the rival numbers Pi and Tau.

White Day 2014
March 14, 2014 in the World

White Day 2014 is on March 14. The day is celebrated in Japan one month after Valentine’s Day. It is also observed in South Korea, Taiwan and China. In Japan, Valentine’s Day is observed by females who present chocolate gifts , usually to a male, as an expression of love, courtesy or social obligation.

A handmade chocolate is usually preferred by the receiver, because it is a sign that the receiving male is the girl’s “only one”. On White Day, the converse happens: males who received a honmei-choco (“chocolate of love”) or giri-choco (“courtesy chocolate”) on Valentine’s Day are expected to return the favor by giving gifts, usually more expensive.

Traditionally, popular White Day gifts are cookies, jewelery, white chocolate, white lingerie and marshmallows. Sometimes the term sanbai gaeshi (“thrice the return”) is used to describe the generally recited rule that the return gift should be two to three times the cost of the Valentine’s gift.

White Day was first celebrated in 1978 in Japan. It was started by the National Confectionery Industry Association as an “answer day” to Valentine’s Day on the grounds that men should pay back the women who gave them chocolate and other gifts on Valentine’s Day.

Learn about Butterflies Day takes place on March 14, 2014. OK, let’s start and learn something about butterflies: A butterfly is a mainly day-flying insect which includes the butterflies and moths. The butterfly’s life cycle consists of four parts: egg, larva, pupa and adult. Butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight.

Butterflies feed primarily on nectar from flowers. Some also derive nourishment from pollen, tree sap, rotting fruit, dung, decaying flesh, and dissolved minerals in wet sand or dirt. Butterflies are important as pollinators for some species of plants although in general they do not carry as much pollen load as bees.

National Potato Chip Day
March 14, 2014 in the USA

Today is National Potato Chip Day! Did you know that Americans consume 1.2 billion pounds of potato chips each year? It’s the nation’s favorite snack food!

An Irish chef named George Crum invented potato chips in Saratoga Springs in 1853. One day, a picky customer kept sending his fried potatoes back to the kitchen, complaining that they were too thick and soggy. Crum responded by slicing the potatoes so thin that they couldn’t be eaten with a fork. The customer was so pleased with Crum’s crispy creation that they became a regular item on the restaurant’s menu!

Potato chips are commonly served as an appetizer, side dish, or snack. The basic chips are cooked and salted; additional varieties are manufactured using various flavorings and ingredients including seasonings, herbs, spices, cheeses, and artificial additives.

To celebrate National Potato Chip Day, enjoy some of your favorite potato chips with your lunch or dinner!
