13 is the 6th prime................6 is the 1st perfect number............................13 is the closest prime to the 1st zero.......................................a line at 1/2............1/2 of 13 is like dead center of the prime fundamental...................






2 + 4.5 = 6.5............................6.5 + 4.5 = 11...............dead center matches the sum............6.5 and 65........fractal patterns............................and the 459045 in e......................the beg of that .............4.......is the 11th digit.................like a 1:1.....square root of 2...............45/45 degree right triangle...............................

6 + 5 = 11..................middle like end.............or beg.......................2 = 1 + 1.................2 - 11............................symmetry.............and spin.........full circle........like the square root of 13...........................which begins......3.60..............
