22/7........matches pi to the 1st 3 numbers.........and is like both e and 72.....like the rule of 72....which is like e, backwards......the 1st 2 numbers of e..............like the critical line at 1/2.....symmetry Emmy N..


72.....like 2 360s....two basic geometric figures...a square and a circle.....the 2 square is the minimum square needed to fully inscribe the unit circle.....a 1 and a 2....just like.1/2.....the critical line.ber.
