Celebrating Pi Day | UDaily (UDaily)

Sebastian Cioaba, professor in the Department of Mathematical Sciences, explains how the Greek mathematician Archimedes calculated an accurate estimation of pi.

Cioaba grew up in Romania and had never heard of Pi Day until he came to Canada as a graduate student. Likewise, Cioaba said he appreciated his department colleagues, including the late Pam Irwin — yes, PI — for their enthusiasm in helping students. “Students, and people in general, think that the mathematics landscape consists of separate islands that aren’t connected, and that's the opposite. It’s kind of like this lofty dream — they try to become circles, but they never become circles. Greek mathematician Archimedes is credited as one of the first people to calculate an accurate estimation of pi’s value, sometime around 250 BC. It was introduced by English mathematician William Jones in 1706, and use of the symbol was popularized by Swiss mathematician Leonhard Euler, who adopted it in 1737. “When people think about pi, the fixation is so much on the digits — how many you can memorize. Divide the circumference of Earth by its diameter and you get 3.14. “I think any attention to math is great,” Cioaba said. In celebration of the most famous mathematical constant, people eat pie and memorize digits on Pi Day — Tuesday, March 14, or 3/14 as it's written in many countries. Divide the circumference of a baseball by its diameter and you get 3.14. In 2019, the United Nations Educational, Scientific and Cultural Organization (UNESCO) proclaimed March 14 as the International Day of Mathematics.

11 fun facts to help celebrate Pi Day (Big Think)

It's the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!

[many examples of formulae](https://en.wikipedia.org/wiki/List_of_formulae_involving_%CF%80) that [one can calculate](https://en.wikipedia.org/wiki/Euler%27s_continued_fraction_formula), repetitively, to arrive at a good approximation for π, but the advantage of the three shown above is that they’re simple, straightforward, and provide an excellent approximation with only a relatively small number of terms. Right in that location, before you reach the star Alnath, you’ll find the location of the star cluster Messier 38, where [a red-green-blue color composite](http://www.emilivanov.com/CCD%20Images/M38_LRGB.htm) clearly reveals a familiar shape. For example, using only [the first 10 terms of the final series](https://www.google.com/search?gcx=w&sourceid=chrome&ie=UTF-8&q=4%2F%281%2B1%2F%283%2B4%2F%285%2B9%2F%287%2B16%2F%289%2B25%2F%2811%2B36%2F%2813%2B49%2F%2815%2B64%2F%2817%2B81%2F%2819%2B100%2F21%29%29%29%29%29%29%29%29%29) shown gives the first 8 digits of π correctly, with only a small error in the 9th digit. One of the most bizarre properties of π is that it shows up in some really unexpected places. In fact, one of history’s most famous unsolved math puzzles is to create a square with the same area as a circle using only a compass and straightedge. If you can write down a polynomial equation with integer exponents and factors, and only use sums, differences, multiplication, division, and exponents, all of the real solutions to that equation are real algebraic numbers. By that account, π is irrational, but so is a number like the square root of a positive integer, such as √3. But calculating the area of a regular polygon is easy, especially if you know the formula for the area of a triangle, and realize that any regular polygon can be broken up into a series of isosceles triangles. [Milü](https://en.wikipedia.org/wiki/Mil%C3%BC), discovered by Chinese mathematician [Zu Chongzhi](https://en.wikipedia.org/wiki/Zu_Chongzhi), was the best fractional approximation of π for about 900 years: the longest “best approximation” in recorded history. The more sides you make to your regular polygon, in general, the closer you’ll get to the value of π. 2.) π cannot be calculated exactly, because it is impossible to represent as a fraction of exact (integer) numbers. Pronounced “pi” and celebrated worldwide by baking enthusiasts as “Pi day,” it’s also a great opportunity to share some facts about π with the world.

Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. It is a non-repeating and non-terminating number that has been calculated to trillions of digits, but is commonly approximated to 3.14. Students can put their math mettle to the test to solve real problems faced by NASA scientists and engineers. Some people also use Pi Day as an opportunity to raise awareness about the importance of math and science education. More than [30 puzzlers from previous challenges](https://www.jpl.nasa.gov/edu/teach/tag/search/Pi+Day) are also available. To find pi, aka the Greek letter p, you simply divide any circle’s circumference by its diameter.

Happy Pi Day! From Mars landing to exploring new planets, here's ... (The Indian Express)

From landing parachutes on Mars to finding out whether distant exoplanets are habitable, here is how NASA uses Pi in its everyday work.

Using this figure and formula with pi, scientists can estimate the angular velocity of the object in question, whether it is an asteroid or comet. It needs to receive the right amount of heat for life to happen, but too much heat can stop it altogether. Pi helps them decide how big the parachute needs to be so that it can generate enough drag to slow down an object’s descent. Pi is not just useful when you reach a planet and map, scientists need it to search for distant planets as well. It is Pi day, one of the few days of the year when mathematicians and the scientists who practice it are celebrated. This is why March 14 is celebrated as the day commemorating one of the most well-known symbols in mathematics.

And so she showed me the true essence of math at home, so that when I was bored by having to do timetables and answer questions at school, I knew that there was more to math than that," she remembers. The recipe is a playful starting point for discussing the process of abstraction — looking for underlying similarities between items like structures, patterns or properties. She loves pure math for the same reason. The audio engineer was Robert Rodriguez. "Just associating math with fun instead of with trauma is a good start." Eugenia's start with mathematics was joyful and came early in life. Eugenia loves this recipe because, yes, it has an ingredient — but really, it's all about the process. "And just as a recipe would be a bit useless if it omitted the method, we can't understand what math is unless we talk about the way it is done, not just the things it studies," she writes in her book. See, since she was a child, baking and math were linked. Making math fun and relatable to the masses is a lifelong ambition for Eugenia.

National Pi Day: 3.14 Things to Know About Pi (NBC New York)

Pi Day is celebrated annually on March 14 since the first three numbers of the mathematical constant are 3, 1 and 4.

Simply put, squaring the circle is the impossible task of finding the area of a circle by finding the area of a square around it. Goodwin, a physician, convinced a well-known mathematical monthly newspaper that he had solved what mathematicians had tried to do for generations: squaring the circle. The matches' length must be equal to the distance of the two parallel lines. It seems that the Egyptians used pi in the construction of the Great Pyramid because when the perimeter is divided by its height, one gets a close approximation to 2π. Goodwin claimed that pi was 3.2 instead of a continuous number. If you drop a hundred of them at random on the floor, the points touching a line will equal pi,” Ball said. The bill never became a law thanks to Professor C. In 1897, Indiana state legislators tried passing a Pi Bill that legally defined pi as 3.2. It’s the same result if one divides the circumference of a circle by its radius. “He approached that putting a six sided figure into a circle, then made it 12 sided, and went all the way up to a 96-sided polygon.” “There’s a wonderful way to find pi for yourself. But Professor Strogatz stressed that the meme is misleading.
