This last one if printed out is supposed to be 600miles long ... if its a
normal
printer 132 columns 60 lines its 63,000 Sheets 21 boxes of paper or 12 Miles
of paper I guess the 600 miles is for one line in Pica.. Cray-2 and IBM-VF
Supercomputers
several months of interupted time. Maybe Pi will come out in CDRom soon.
Maybe someone can append more to this list or maybe someone from Columbia can
give a bit more detail on the 500M digits.
The Biblical refrences you asked apout... the diameter of solomns temple bowl
and the circumference are given... in both th non cronological books
lets look for beowolf .. and trhe golden apples..
