Neil DeGrasse Tyson is known for dropping scientific knowledge on us via Twitter, and today was no different. Today, Tyson shared an interesting way to find your hat size using pi.
Being that today is Pi Day (March 14, or 3/14), Tyson's timing in sharing factoid on Twitter was perfect.
Lots of people struggle with finding a hat that fits well, and now knowing how that size is calculated, it's no wonder.
Not that anybody asked, but… Measure the circumference of your head in inches, then divide that number by Pi. Tha… https://t.co/8m8qtK7onD— Neil deGrasse Tyson (@Neil deGrasse Tyson) 1552568613.0
A few people were surprised at the information.

@neiltyson Thank you! I'm glad you mentioned it even if no one asked. I have a hard time finding a hat because I do… https://t.co/GvqJfAJ2e9— IIISTARGATEIII (@IIISTARGATEIII) 1552583901.0
@neiltyson @kharyp Mind. Blown. Science is so awesome!!! 🤩— Birgit Nazarian (@Birgit Nazarian) 1552569303.0
@neiltyson This is actually really useful— Robert Durst (@Robert Durst) 1552572586.0
Others were confused as to how it is useful, since our heads aren't perfectly spherical (they don't have to be, that's just how hats are measured).
@neiltyson Only Charlie Brown has perfect spherical head.— John Friedman 🌎 (@John Friedman 🌎) 1552583419.0
@neiltyson Nobody’s head is even close to a perfect sphere.— not cool, dana. (@not cool, dana.) 1552569554.0
This isn't a universally useful piece of knowledge, apparently.
@neiltyson I beg to differ. https://t.co/CPZNIB0yO2— Logendra Naidoo 🌎 (@Logendra Naidoo 🌎) 1552569021.0
Several people appreciated the timing of Tyson's factoid.

There were puns aplenty.
@neiltyson Nice hat trick, Neil.— George Takei (@George Takei) 1552576307.0
@neiltyson This explains the pork pi hat.— Bob Fisher (@Bob Fisher) 1552569245.0
Tyson is largely known for explaining complex scientific concepts in ways that are easy to understand. A person's hat size may not seem overly complicated, but practical uses for pi are always good to know.
