nahud | http://www.bbc.co.uk/berkshire/content/articles/2006/12/06/divide_zero_feature.shtml funny read, can't believe it actually got posted as news on bbc. poor grade school kids | December 7, 2006, 5:08 PM |
Rule | Haha, I can solve difficult problems by making up answers and giving them a symbol and a cool name too :P. How enlightened everyone shall be! From comments: "Good idea, because it happens all the time that pacemakers divide by zero and stop working." | December 7, 2006, 7:50 PM |
Yoni | Pfffffffft. I can't find the video. | December 8, 2006, 10:01 AM |
l2k-Shadow | OK, so basically instead of an error, we'll now use a number which is not plottable on the number line. That makes much more difference as to solving problems that divide by 0. Can someone enlighten me on how should we graph 1/nullity plz? ::) what people can do now-a-days to get famous. *sigh* | December 9, 2006, 3:30 AM |
rabbit | It's easy. We make a new coordinate system to graph numbers of nullity. | December 9, 2006, 1:11 PM |

Yoni | Sorry, I read his papers 2 weeks ago and forgot to post my comments. Here. [quote] Ewok 2006-12-08 13:21:15 oh Ewok 2006-12-08 13:21:16 http://www.bookofparagon.com/News/News_00012.htm Ewok 2006-12-08 13:21:21 here, you can understand it Ewok 2006-12-08 13:21:24 *runs* Yoni @ ALSA! 2006-12-08 13:26:39 now THAT overview is written in a more mathematical language Yoni @ ALSA! 2006-12-08 13:26:43 unfortunately it still looks like crap Yoni @ ALSA! 2006-12-08 13:27:24 well, it's only 13 pages Yoni @ ALSA! 2006-12-08 13:27:26 i'll read it Yoni @ ALSA! 2006-12-08 14:13:07 the paper is badly written Yoni @ ALSA! 2006-12-08 14:13:53 and contains mistakes Yoni @ ALSA! 2006-12-08 14:14:16 and stupid propositions Yoni @ ALSA! 2006-12-08 14:14:24 basically, the paper says: Yoni @ ALSA! 2006-12-08 14:14:51 "we define Nullity and a few axioms, and feed the definitions to axiom-processing software - here are the results." Yoni @ ALSA! 2006-12-08 14:15:33 also, some of the definitions surrounding nullity make it seem really ugly and unnatural, and I doubt its usefulness Yoni @ ALSA! 2006-12-08 14:15:50 he had to break a few ground rules to fit it in Yoni @ ALSA! 2006-12-08 14:28:39 if I analyze the definitions of nullity, I can classify them into 2 categories: 1. Preservation of nullity: nullity + anything = nullity nullity * anything = nullity -nullity = nullity (nullity)^-1 = nullity 2. Reaching nullity: infinity - infinity = nullity infinity * 0 = nullity [this is the basis for the definition of nullity as 0/0, since 0^-1 = infinity according to his paper] Yoni @ ALSA! 2006-12-08 14:29:12 #2 show nullity to be nothing more than renaming the old word "undefined" that we've always used Yoni @ ALSA! 2006-12-08 14:29:33 and #1 show nullity to be something that propogates through your equations completely, making it completely useless anyway Yoni @ ALSA! 2006-12-08 14:30:26 I seriously doubt that this concept hasn't already been introduced by countless programmers working on algebra systems Yoni @ ALSA! 2006-12-08 14:32:01 in conclusion, Anderson isn't a total idiot, but his idea is unimportant and mispresented (it could have been presented as a method for checking software axiom checking systems, which he used) Yoni @ ALSA! 2006-12-08 14:32:04 THERE. Yoni @ ALSA! 2006-12-08 14:35:27 the 2nd paper tries to introduce nullity to infi, and it basically says "whenever you said the limit doesn't exist, now you should say it equals to nullity" Yoni @ ALSA! 2006-12-08 14:35:34 also, it references wikipedia Yoni @ ALSA! 2006-12-08 14:35:43 which is highly unprofessional, imo Yoni @ ALSA! 2006-12-08 14:38:24 "why does this difficulty persists" Yoni @ ALSA! 2006-12-08 14:38:26 bad grammar, too [/quote] | December 22, 2006, 10:58 AM |
Rule | I don't think we should expect much if he is publishing his abstract mathematical ideas in the journal for "Photo-Optical Instrumentation Engineers." In his interview he clings to the notion that his work was developed for computer science, so it is natural that mathematicians wouldn't initially accept or welcome it. But he hasn't even published this work in a computer science journal! | December 23, 2006, 4:25 AM |
