What is Pi?
“Probably no symbol in mathematics has evoked as much mystery, romanticism, misconception, and human interest as the number Pi.”
~William L. Schaaf, Nature, and History of Pi
Pi (often represented by the lower-case Greek letter π), one of the most well-known mathematical constants, is the ratio of a circle’s circumference to its diameter. For any circle, the distance around the edge is slightly more than three times the distance across.
Typing π into a calculator and pressing ENTER will yield the result 3.141592654, not because this value is exact, but because a calculator’s display is often limited to 10 digits. Pi is actually an irrational number (a decimal with no end and no repeating pattern) that is most often approximated with the decimal 3.14 or the fraction 22/7.
Pi Day started being celebrated in 1988 at San Francisco’s Exploratorium.
Is “Pi” considered an irrational number?
Answer: Yes, pi is an irrational number.
Explanation:
Pi is a Greek letter (π), and one of the most well-known mathematical constants.
It is the ratio of a circle’s circumference to its diameter, which is always constant.
Pi (π) approximately equals 3.14159265359… and is a non-terminating non-repeating decimal number.
Hence ‘pi’ is an irrational number.
Thus, we can say that pi is an irrational number.
Not even the computing power of Google Cloud could get much further than, oh, say… 100 Trillion digits to answer Pi. See the link above.
Random Fact:
Albert Einstein Birth Anniversary: Albert Einstein won the 1921 Nobel Prize in Physics for his services to theoretical physics and discovery of the law of the photoelectric effect. Albert Einstein is known as one of the greatest physicists of all time and is said to have minted the “Definition of Insanity.”
Who first is attributed to a common saying, “What is the definition of insanity?“
The definition of insanity is doing the same thing over and over again and expecting a different result. These words are usually credited to the acclaimed genius Albert Einstein.
