Simply watch all 10,000 digits of Euler's number scroll across the screen. The script I've created to contain these many digits (Python): from decimal import Decimal, getcontext, ROUND_HALF_EVEN import math getcontext().prec = 10000 E = Decimal(0) for i in range(getcontext().prec + 20): E += Decimal(1) / math.factorial(i) print(E)
