Interesting Math History 


Question : 
What is the 'Ludolphian Number' ? 
Answer : 
As the end of Sixteenth Century Ludolph Van Ceulen calculated 35 decimal place for pi. In his will, he requested that these
35 numbers be engraved on his tombstone.

In Germany they still refer to this number as Ludolphian Number.

Around 200 BC, Archimedes of Syracuse found that pi is somewhere about 3.14.
Pi (which is a letter in the Greek alphabet) was discovered by a Greek mathematician named Archimedes.

In June 1995, the Japanese mathematician Yasumasa Kanada found p correct to 3,221,220,000 decimal places.

Thus, p = 3.14159265358979....
