Lindemann (1852-1939), a German, was a mathematician at the end of the 19th century and the beginning of the 20th century. His main contribution was to prove thatPiπ is a transcendental number. The so-called transcendental number is a real number that cannot be used as the root of a rational coefficient polynomial.[1]
Previous people calculated pi to explore whether pi isRecurring decimal。Since Lambert proved that pi is an irrational number in 1761 and Linderman proved that pi is a transcendental number in 1882, the mystery of pi has been unveiled.
