    Testing primes using factorials

    This method is more of an inefficient and therefore unpractical method of testing primes. With the RSA encryption system being used, computers are required to test primes up to hundreds of digits long, and with this method, even the floor-square root factorial, which would be around [15 to...

    Followup: pi on curved surfaces

    If C/d was not pi in curved space, assuming we say it is pi', then pi' =/= pi and the infinite series of pi, like the slow convergent one 4(-1)^n/(2n+1)from n=0 -> infinity, would be incorrect in measuring the circle stuff. also, it would mean that e^(pi*i) is -1, but e^(pi'*i) is also -1 on the...

    Why is the number zero crucial in math and science?

    No zero? Means no difference quotient, which means no differentiation, which means no integration, which means an extremely difficult way to calculate area between the x-axis and a curve/line, which means no calculus, which means I have nothing to learn in seventh grade in math. also, zero is...

    Testing primes using factorials

    This would be a much easier fraction to deal with: With the (n-1)!/n fraction, you would be pretty much checking all the numbers that could not divide n. For example, if we picked 101, we would be checking all numbers up to 100, but with the fraction above, we would be checking only up to 10...
