I did. Sunday afternoon.
Hermite proved that "e" is transcendental, but it was Ferdinand Lindemann who proved that "pi" is transcendental.

It is a rational number. One way this can be proved is that it can be represented as a fraction: 7/2.
No, because according to one definition, an Armstrong number can have only three digits.Armstrong numbers belong to a class of numbers, called Narcissistic numbers. A Narcissistic number of n digits must equal the sum of the nth power of its digits.So, the smallest 4-digit Narcissistic number is 1634 = 1^4 + 6^4 + 3^4 + 4^4.The largest Narcissistic number is the 39-digit numbers:115132219018763992565095597973971522401.It has been proved, by D Winter in 1985, that there can be no larger Narcissistic number in base 10 arithmetic.
The Spitfire proved superior as a smaller number of Spitfires defeated the Luftwaffe fighter forces in Battle of Britain.
He proved that pi is an irrational number.
proved that America was number one in technology and therefore the number one superpower
Euler.
From Wikipedia: "In 1882, German mathematician Ferdinand von Lindemann proved that π is transcendental, confirming a conjecture made by both Legendre and Euler"
Pi is an irrational number. Johann Heinrich Lambert proved that in the late 18th Century.
