Pi Syndrome

Someone who is prone to coining new words or phrases on or about the number π once their mind’s eye leads them to see how an apparently unrelated idea or concept within or outside math could be linked to the most famous constant in mathematics.
While writing the manuscript for “Never Write a Math Book Without π,” Ian has been struck with pi syndrome since the start of the pandemic.

Pi Sector

The minor sector formed when the two hands of a circular clock at 3:14 are imaginarily extended to its edge or circumference.
What fraction of a clock is the pi sector? 13/360

Pi Lockdown

When the frequency of the number π gracing the pages of reputable math journals took a dive during the pandemic, when both male and female mathematicians and math educators worldwide, working from home, felt half-productive or fell sick from Covid-19.
Guesstimate how many pure mathematicians globally had some mental health issues during the pi lockdown in 2020–2021.

pi time

pi = approximately 3.14
therefore, when the clock shows 3:14, it is Pi Time!

An excellent time to eat pie.

Pi-Head

A person fascinated with the decimal expansion of pi (3.14...)
It would take a Pi-Head to know how far pi has been expanded by today's super computers

Pi Moment

When the public announcement of the proof of a famous unsolved problem on π turned out to be short-lived, because the result was later found to contain grave errors.
Mathematicians worldwide were excited to hear that the number (π + e) has been proved to be transcendental (i.e., its value can’t be the root of an algebraic equation with rational coefficients), but the news was nothing but a pi moment.
