Description: By starting with the prime number 71, you can make a simple recipe for pie. If 71 is the denominator, a numerator of 208 yields two important mathematical constants with +/- 15. 223/71 gives you a very close pi approximation, and 193/71 is just thousandths away from Euler's number. Put them together and you've got pi(e)! But the weird part here isn't the fraction, it's the role of 71, which has a series of strange properties. AND WHAT HAPPENS IN THE YEAR 2059? #shorts
