RonJonSurfer Posted January 4, 2006 Report Share Posted January 4, 2006 Mo. Researchers Find Largest Prime Number By GARANCE BURKE, Associated Press Writer KANSAS CITY, Mo. - Researchers at a Missouri university have identified the largest known prime number, officials said Tuesday. The team at Central Missouri State University, led by associate dean Steven Boone and mathematics professor Curtis Cooper, found it in mid-December after programming 700 computers years ago. A prime number is a positive number divisible by only itself and 1 — 2, 3, 5, 7 and so on. The number that the team found is 9.1 million digits long. It is a Mersenne prime known as M30402457 — that's 2 to the 30,402,457th power minus 1. Mersenne primes are a special category expressed as 2 to the "p" power minus 1, in which "p" also is a prime number. "We're super excited," said Boone, a chemistry professor. "We've been looking for such a number for a long time." The discovery is affiliated with the Great Internet Mersenne Prime Search, a global contest using volunteers who run software that searches for the largest Mersenne prime.

Earth-Angel Posted January 4, 2006 Report Share Posted January 4, 2006 I witnessed something pretty impressive today x = (2^(y/12)) * 0.03125f This worked out the way to map an image of which keys were used in a song at that particular point, giving you a visual of a song being played on a keyboard. Totally off topic, of course Link to comment Share on other sites More sharing options...

PSYCHOcatholic Posted January 4, 2006 Report Share Posted January 4, 2006 A math teacher in 8th grade, proved to me that 1+1=0 Ive looked all over google for the proof....but cant seem to find it. It is possible though. Link to comment Share on other sites More sharing options...

Shawna Posted January 4, 2006 Report Share Posted January 4, 2006 "We're super excited," said Boone, a chemistry professor. "We've been looking for such a number for a long time." so, now that they have this number, will it cure cancer, or instill world peace? Link to comment Share on other sites More sharing options...

PSYCHOcatholic Posted January 5, 2006 Report Share Posted January 5, 2006 Mmk, i found something similar. 1+1=0...well its not the final step it seems you have to go an extra step and 1+1=1 I got this from the Dr. Math website... www.mathforum.org Let a = 1 and b = 1. Therefore a = b, by substitution. If two numbers are equal, then their squares are equal, too: a^2 = b^2. Now subtract b^2 from both sides (if an equation is true, then if you subtract the same thing from both sides, the result is also a true equation) so a^2 - b^2 = 0. Now the lefthand side of the equation is a form known as "the difference of two squares" and can be factored into (a-*(a+. If you don't believe me, then try multiplying it out carefully, and you will see that it's correct. So: (a-*(a+ = 0. Now if you have an equation, you can divide both sides by the same thing, right? Let's divide by (a-, so we get: (a-*(a+ / (a- = 0/(a-. On the lefthand side, the (a-b)/(a- simplifies to 1, right? and the righthand side simplifies to 0, right? So we get: 1*(a+ = 0, and since 1* anything = that same anything, then we have: (a+ = 0. But a = 1 and b = 1, so: 1 + 1 = 0, or 2 = 0. Now let's divide both sides by 2, and we get: 1 = 0. Then we add 1 to both sides, and we get what your programming teacher said, namely: 1 + 1 = 1. Link to comment Share on other sites More sharing options...

Levis Posted January 5, 2006 Report Share Posted January 5, 2006 You can't use two variables to represent the same constant. Link to comment Share on other sites More sharing options...
PSYCHOcatholic Posted January 5, 2006 Report Share Posted January 5, 2006 Thats where the gray area comes in... And another part of the gray area dividing by (a- You cant divide by the number Zero...but alot of people think of zero as "nothing"...if you divide by nothing the number stays the same right? Trust me, this sounds a whole lot better in my head, so ill stop here! lol i hate math. Link to comment Share on other sites More sharing options...

Levis Posted January 5, 2006 Report Share Posted January 5, 2006 0/(a- works but you can't do (a-b)/0. That would give infinity. I think the major flaw still lies in using two variables for the same constant. Link to comment Share on other sites More sharing options...

RonJonSurfer Posted January 5, 2006 Author Report Share Posted January 5, 2006 My point in bringing this up was to illustrate the sound mathematical principles used in this song: "Nothing From Nothing" (As recorded by Billy Preston) Nothing from nothing leaves nothing You gotta have something if you wanna be with me Nothing from nothing leaves nothing You gotta have something if you wanna be with me I'm not tryin' to be your hero 'Cause that zero, is too cold for me I'm not tryin' to be your highness 'Cause than minus is too low for me. Nothing from nothing leaves nothing And I'm not stuffin', believe you me Don't you remember I told ya, I'm a soldier In the war on poverty, yeah Nothing from nothing leaves nothing You gotta have something to be with me Nothing from nothing leaves nothing You gotta have something to be with me.

Levis Posted January 6, 2006 Report Share Posted January 6, 2006 Ooops, my bad! Psyche, you are so right, it just didn't strike me when it should have and my ex-maths tutor would be glaring at me at this point. You can't divide by (a-... I forgot they hold the same value so that would be 0 and you can't divide by 0. This struck me while I was washing my hair and it's been plaguing me all morning (Head and Shoulders must be having some special ingredient). Now that I've cleared my conscience, I'm off for lunch.
