Here's all the inspiration you need in life

Pi can actually be calculated to over one trillion digits beyond its decimal point. This uniqueness of this mathematical denomination has often resulted in discussions, talks, debates and even has references in popular culture including movies and comics. As Pi is an irrational and transcendental number, it continues infinitely without repetition or pattern. Hence for normal calculations, only a few digits are used. Its infinite nature also has been the subject to various memorising competitions also. FYI, Albert Einstein's birthdate was born on March 14, 2018, which is the same as Physicist Stephen Hawking's death date.
