15.............................is in many places..........a one and a 5.............3 fives...........14.13i is between 14i and 15i...................the 1st 5 primes connect single digits to double digits..............the 1st 5 non primes do the same........................

4 is in the middle of single digit primes..........15 is in the middle of double digit primes........2, 3, 5, 7...................................4 is the most center number............whole number................11, 13, 17, 19...........................15 is dead center...................................two from 13..............2 from 17.............4 is one more than 3 and one less than 5................but there is asym................b/c 2...............is 2 less than 4................and 7..........is 3 more............so many 2s and 3s..............3s and 2s..........3/2 = 1.5...................but 15 is equidistant from 11 and 19........................................4...............in distance.......................4 being the most center number of the 1st 4 primes............written like that.......1st 4...............14i............................and 15 is the most center number...........in the 1st series............10 series......zero to zero.............of the 1st 4 double digit primes..........4 + 15 = 19.......................................two nineteens in e..........the 1st 10 digits of e............"the curious repetition of 1828"...............two blocks of 1828...............added digit by digit.............single digits..........1828 sums to 19..........2 19's..........1/9 to 1/10............added straight across.............numerator to numerator ................denominator to denominator..........using the zero dimension.....1 + 1 = 2............9 + 10 = 19........................two 19s................








15 is the center number............from 10 - 20...........................matching double digits to double digits..............1 to 2...........like 1/2..........the c line..............14.13 i.............is between 14i and 15i..................................3 fives in the square root of 13...........which starts out.......3.60555.............3 fives..............5 + 5 + 5 = 15..............................

The triangle...............is the square root of 3 equil triangle............the only kind that can be inscribed in the unit circle................the square...................very crude one...........is the square root of 2 square..........the only kind of square..........that can be inscribed in the unit circle.................they overlap at the top......................(0, 1)..............................on the Y axis.............1 up..........0 and 1.............1/2 is right between them.................................a square has 360 degrees..........the same as a circle.............................................an equil triangle has 3 60 degree angles.....................see a pattern?.....................................so the other two angles are 15 and 15...............between the square root of 3 triangle and the square root of 2 square.................b/c they are symmetrical...............and the difference between 90 and 60 is 30.........half of 30 is 15.................................15 is dead center from 10 to 20.............................on either side...........is 11 and 13..............and 17 and 19...........11 + 13 = 24.....................................17 + 19 = 36...................36............like full circle...............11 + 13 + 17 + 19 = 60.............1/6th full circle and like a truncated full circle..................
