West Palm Beach, Fall.
Many people will mark this day with a piece of pie – sweet, sewage or even pizza.
In direct words, PI is a permanent of mathematics that reflects the proportion of circle tawaaf from its diameter. It identifies numerous formulas used in physics, astronomy, engineering and other fields, which are met by thousands of years of ancient Egypt, Babylon and China.
Pie De Day itself is 1988, when physicist Larry Shaw launched the celebrations at the San Francisco Explorem Science Science Museum. After two decades, the holiday really did not get national identity. In 2009, the Congress nominated March 14 in hopes of creating more interest in mathematics and science – to become a big day. Properly, this day is also Albert Einstein’s birthday.
There is something else about the origin of the holidays and how it is celebrated today.
What is PI?
PI can calculate the frame of the circle by measuring diameter-the straight distance in the middle of the drain-and multiplied it with a 3.14 plus number.
It is considered a permanent number and is infinite, that is, it is irrational in terms of mathematics. Long before computers, historical scientists like Ishaq Newton spent several hours calculating the decaying places. Today, using sophisticated computers, researchers have come up with trillions of digits for PI, but there is no end.
Why is it called PI?
It was not named until 1706, when Welsh mathematician William Jones began using the Greek symbol for that number.
Why the letter? This is the first Greek letter in the words “circle” and “frame” and PI is the ratio of the circle of the diameter – or frame -.
What are some practical use?
The number is the key to pointing to an antennate to a satellite. This helps to detect everything from the size of the cylinder to the printers from the refinery equipment, from the size of the cylinder to the size of the paper rolls.
PI is also useful in determining the necessary scale of a tank that serves heating and air conditioning system in different sizes buildings.
NASA uses PI on a daily basis. It is key to the positions of orbit, planets and other heavenly entities, rocket propolus elements, spacecraft communications and even the proper deployment of parachutes when a vehicle breaks down on Earth or lands on Mars.
Using only nine digits of PI, scientists can calculate Earth’s tawaaf so that only one -inch of an inch (0.6 cm) for every 25,000 miles (about 40,000 km) is an error of about one quarter.
Although, it’s not just math
Each year, the San Francisco Museum, which prepared holidays, arranges events, which includes a parade around the circular plaque, called Pie Mazar, called 3.14 times – and then, of course, with a lot of pie festivals.
All over the country, there are now many incidents on the college campus. At Florida’s Atlantic University in Florida, Jupiter Mathematics Club students are hosting a pi -day extravagant to target math professors with a pie, as well as a competition that can memorize PI’s most digits.
Restaurants across the country, including some pizza chains, also offer $ 3.14 special at PID.
NASA has placed its annual PID challenge online, which features many games and puzzles, some directly from the space agency’s own playbox, such as calculation of a discharge or orbit of the moon rover every day to survey a particular lunar area.
What about Einstein?
Einstein, probably the world’s most famous scientist, was born in Germany on March 14, 1879. The unlimited number of pie was used in many of its progress, and now the Pie Day provides the world another reason to celebrate its achievements.
In the balance of a little mathematics, the renowned physicist Stephen Hawking passed away on March 14, 2018 at the age of 76. Nevertheless, PI is not a great number. He had to say once:
“One of the basic principles of the universe is that nothing is perfect. Perfection does not exist. Without incomplete, neither you nor me will be present. “
