The Greek letter 𝜋 𝜋 (pi) is pronounced like the English word "pie" (as in apple pie) in most English-speaking contexts, rhyming with "high" or "my" (/paɪ/). While in Modern Greek and some European contexts it's pronounced closer to "pee" (like the letter P), the common mathematical pronunciation in English is "pie," making it a homophone for the dessert.
based on comments, it seems 'pee' comes from the original Greek form, and over the centuries most English speaking countries pronounced this as PI, whereas in Greece and a fair amount of Europe still call it 'P', as we would pronounce pee.
The mathematical pi is defined as “the ratio of the circumference of a circle to its diameter.” It's also known as Archimedes' Constant, after the ancient Greek mathematician of the same name, who, in addition to coming up with an algorithm for calculating pi, also invented an early type of irrigation pump called the ...
Pi (/ˈpaɪ/; Ancient Greek /piː/ or /peî/, uppercase Π, lowercase π, cursive ϖ; Greek: πι) is the sixteenth letter of the Greek alphabet, representing the voiceless bilabial plosive IPA: [p].
The uppercase Pi ∏ symbol stands for the product operator throughout mathematics, just as the uppercase Sigma ∑ symbol would describe the sum operator. Think of the following analogy alliteration: Pi is to a Product ... as Sigma is to a Sum.
Once you have that down, say "girl." Notice how there isn't any vowel sound in between—just a clear shift from "g" to "r"! While pronouncing "girl," keep your lips rounded. Remember to keep your tongue up as you shift to the dark "L." This pronunciation is all about adding a bit of attention during the transition.
The sequence 999999 occurs at decimal 762 (which is sometimes called the Feynman point; Wells 1986, p. 51) and continues as 9999998, which is largest value of any seven digits in the first million decimals.
The 100-trillionth decimal place of π (pi) is 0. A few months ago, on an average Tuesday morning in March, I sat down with my coffee to check on the program that had been running a calculation from my home office for 157 days. It was finally time — I was going to be the first and only person to ever see the number.
This fractional representation is widely used in classrooms and common calculations, leading to the widespread yet erroneous belief that π is precisely equal to 22/7. While 22/7 serves as a convenient approximation, it does not capture the true essence and value of π.

Someone I know has taken to using the word “wee” meaning to urinate, e.g., “Pretty soon I will need to to wee.” I recognized this as a British replacement for “pee,” along the same lines as “poo” substituting for American “poop,” and I thought it would make for a pretty easy post for this blog.
The digits of pi are infinite. It's an irrational number—one whose decimal never ends and never repeats. Over time, with brilliant minds and brilliant technology, humans have been able to calculate its digits further and further, now forming a 100-trillion decimal tail.
Zeta (UK: /ˈziːtə/, US: /ˈzeɪtə/; uppercase Ζ, lowercase ζ; Ancient Greek: ζῆτα, Demotic Greek: ζήτα, classical [d͡zɛ̌ːta] or [zdɛ̌ːta] zē̂ta; Modern Greek: [ˈzita] zíta) is the sixth letter of the Greek alphabet.
According to Stephen Alomes, a professor of Australian studies at Deakin University, the chant represents "enthusiasm for the tribe" and a "celebration of 'us' ", but at the extreme may act as a symbol of aggressive nationalism and xenophobia.
No, Australia is not 90% white; while a large majority identify with European ancestry (around 76-80% in recent years), a significant and growing portion identifies as Asian, African, Middle Eastern, or Indigenous, making it a highly multicultural nation with diverse ethnic backgrounds, not overwhelmingly white. Recent census data shows European ancestry (English, Irish, etc.) makes up a large chunk, but Asian ancestries are also substantial, with over 17% Asian population and around 3.8% identifying as Aboriginal or Torres Strait Islander, per the 2021 census data from Wikipedia.
Zed is widely known to be used in British English. But it's also used in almost every English-speaking country. In England, Scotland, Wales, Ireland, Australia, India, Canada (usually), and New Zealand, Z is pronounced as zed.
This notation is the symbol ∑ (called "sigma"). This new symbol is a shorthand notation used to represent the sum of a number of terms having a common form. This shorthand notation is referred to as "summation notation" or "sigma notation".
P(A ∩ B) indicates the probability of A and B, or, the probability of A intersection B means the likelihood of two events simultaneously, i.e. the probability of happening two events at the same time. There exist different formulas based on the events given, whether they are dependent events or independent events.
⇒ (the implies sign) means “logically implies that”. (E.g., “if it's raining, then it's pouring” is equivalent to saying “it's raining ⇒ it's pouring.”) The history of this symbol is unclear. ⇐⇒ (the iff sign) means “if and only if” and is used to connect logically equivalent statements.
