Each week, Ben Hopkinson looks back at what’s happened the past 7 days and what was trending on Twitter with the Maritime Hashtag Minute.
This week’s #MaritimeHashtagMinute was #PiDay, a celebration for the mathematical constant Pi (π). In America, 14th March is written out as 3/14, which is Pi rounded to two decimal places.

Happy Pi day! The current date and time (14 March, 1.59pm) resemble 3.14159, the approximation of the mathematical constant Pi, or π. Pi is the ratio of the circumference of a circle to its diameter. The ratio stays the same no matter how big or small the circle is.— The Nobel Prize (@NobelPrize) March 14, 2023

Happy Pi Day! While 3/14 connects to the mathematical constant π -the ratio of a circle’s circumference to its diameter- it's also Albert Einstein's birthday. A memorial to the physicist stands just across Constitution Ave & shows him sitting on an (of course!) circular platform. pic.twitter.com/GPQJV9XR6a— National Mall NPS (@NationalMallNPS) March 14, 2023
It’s #PiDay, the holiday that revolves around circles! To celebrate, we’ve rounded up these scientific sights from our experiments on @Space_Station: a spherical space flame, a zinnia flower with a circular center & a drop of protein solution.— NASA Space Science (@NASASpaceSci) March 14, 2023

There are many days celebrating maths (aren't all days maths days?), but we in Oxford Mathematics have a soft spot for today, Pi Day, for the complex mathematical reason that Pi is the name of our cafe.— Oxford Mathematics (@OxUniMaths) March 14, 2023
So, to celebrate, we baked. pic.twitter.com/9TYRrVeERN
