Famous Transcendental Numbers

The number pi, like other fundamental constants of mathematics such as e = 2.718…, is a transcendental number. The numbers pi and e can be expressed as an endless continued fraction or as the limit of an infinite series. In 1882, German mathematician F. Lindemann proved that pi is transcendental, finally putting an end to 2,500 years of speculation.
