Almost missed #PiApproximationDay.
Today is July 22nd, which some people might write as "22/7".

22/7 = 3.1̅4̅2̅8̅5̅7̅, which is reasonably good as an approximation of π with an error of 0.04 %.

Other neat approximations include:
1337% of π equals 42 (error ~ 74 ppm)
355/113 (error below 100 ppb)
and my favourite:
π⁴ + π⁵ = e⁶ (completely useless, but nails π to 9.2 ppb!)

Do you know any other approximations for π?

Meanwhile, take a look at my wife's car.

Happy Pi Approximation Day! Remember, “Failure is just success rounded down.”

Happy Pi Approximation Day!

(Sadly, this day is always in a holiday, so I can't teach about π today)
