qwertydawom Tonight's topic will be : duality. qwertydawom Indeed, like you may have noticed, in real life, it plays a big part : qwertydawom left/right qwertydawom masculine/feminine qwertydawom right/wrong qwertydawom yin/yang qwertydawom and well, ****** :) qwertydawom who can guess what's hidden? qwertydawom hint : if you add "universe"... Ch4r omgz Ch4r binary! qwertydawom ok, so, about the "male/female", I think you know which symbols are used to represent each of them? Snoop pussy/penis? Megahertz 0-> male Megahertz 0-+ female qwertydawom yes MHz :) egahertz ;) qwertydawom and, have you wondered about their meanings? qwertydawom I mean, "why" these symbols? Megahertz no qwertydawom Well, for the male one, it has two meanings : qwertydawom - a man with a spear bonusbug .o0(The mirror of the Roman Goddess ... wikipedia rules ;) qwertydawom - a... penis (yes Snoop..) Megahertz "Roman god Mars" qwertydawom <bonusbug> .o0(The mirror of the Roman Goddess ... wikipedia rules ;) --> yes, this is for the female's one Megahertz and venus for the girl Megahertz "men are from Mars women are from venus" ;) qwertydawom indeed :) qwertydawom and, in fact, the male is the intersection in logic qwertydawom and the female... union. qwertydawom Also, you may remember about the "odds/evens". qwertydawom with odd+odd, etc. qwertydawom and the Goldbach's conjecture : every even number is the sum of two primes. qwertydawom (indeed : 4 = 2 + 2) Megahertz .o0( 1+3=4) Megahertz indeed qwertydawom yes, MHz, but 1 isn't prime ;) mu-tiger eh? Ch4r so qwertydawom, how d'you get 2? :/ Ch4r or is 2 not an even number? mu-tiger wait Ignite pwnt mu-tiger 1* itself is 1 mu-tiger and not times anything else Ch4r I guess you can add 3 and -1 for 2... mu-tiger how is 1 not prime? Ch4r err Ch4r no Ch4r 5 and -3* Ch4r if that counts. Ch4r mu-tiger, it just isn't Ch4r it's special qwertydawom read the previous lectures mu :p mu-tiger k qwertydawom yes, Ch4r, the conjecture is for every number greater than 2 ;) Ch4r oh, ok qwertydawom ok, now, a little game :) qwertydawom Ch4r and Mu choose respectively an odd number for the 1st one, and an even number for the 2nd. Ch4r hmm? Ch4r just choose a random odd number? qwertydawom yes Ch4r ok Ch4r 13 qwertydawom and mu chooses an even number mu-tiger 6 qwertydawom now, Ch4r multiplies his number by an odd number Apr 08 23:01:07 mu-tiger it wouldn't be prime Apr 08 23:01:14 Ch4r mu-tiger, I know ;) Apr 08 23:01:20 Ch4r qwertydawom, ok 13 * 3 = 39 Apr 08 23:01:25 qwertydawom and mu multiplies her number by an even number Apr 08 23:01:39 mu-tiger 2*8=16 Apr 08 23:01:47 qwertydawom now, you add your two final numbers Apr 08 23:01:54 mu-tiger :O Apr 08 23:01:56 mu-tiger ;p Apr 08 23:02:03 Ch4r 55... Apr 08 23:03:40 qwertydawom :) Apr 08 23:03:46 qwertydawom ok, now, you got the rules? Apr 08 23:05:37 Ch4r what rules? Apr 08 23:06:09 mu-tiger the sum of an even and odd number is prime? Apr 08 23:06:34 Ch4r so 2 + 7 = 9... 9 is prime? Apr 08 23:06:39 Megahertz 0.o Apr 08 23:06:40 Ch4r I think I just got sucked into a different universe... Apr 08 23:06:48 mu-tiger me too :( Apr 08 23:06:50 Ch4r lol Apr 08 23:07:00 Ch4r qwertydawom, what rule? Apr 08 23:07:15 Megahertz ctcp ping qwertydawom -.- Apr 08 23:07:23 Ch4r Goldbach's conjecture? Apr 08 23:07:25 Ch4r hmm Apr 08 23:07:37 qwertydawom no no Apr 08 23:07:43 qwertydawom the rules of this little game Apr 08 23:07:45 Ch4r oh Apr 08 23:07:46 Ch4r yeah Apr 08 23:07:51 qwertydawom alright Apr 08 23:08:01 qwertydawom so now, with mu, in private, you do that again Apr 08 23:08:07 qwertydawom and only give me the final number Apr 08 23:08:35 Ch4r ok, hold up Apr 08 23:08:35 qwertydawom and then, I'll be able to guess who took odd/even. :) Apr 08 23:10:05 Ch4r qwertydawom, 65 Apr 08 23:10:13 Ch4r ...we think ;) Apr 08 23:10:21 Ch4r jk Apr 08 23:11:02 Ch4r but yeah... 65... Apr 08 23:11:13 qwertydawom ok Apr 08 23:11:20 qwertydawom ch4r : odd mu : even? Apr 08 23:11:26 Ch4r how'd ya know? ;/ Apr 08 23:11:29 Megahertz lol Apr 08 23:11:58 qwertydawom 1st case : Apr 08 23:12:55 qwertydawom Mu_even * even + Ch4r_odd * odd = odd Apr 08 23:13:54 qwertydawom Mu_odd * even + Ch4r_even * odd = even Apr 08 23:17:39 qwertydawom you gave me an odd number in the end Apr 08 23:17:48 qwertydawom so, I knew that you had an odd number Apr 08 23:18:02 mu-tiger i'll be honest Apr 08 23:18:02 mu-tiger i'm just lost Apr 08 23:19:10 Greenbox well, basically all that has been said is that the result is dependent on the state of Ch4r's number Apr 08 23:19:20 qwertydawom yep Apr 08 23:19:21 Greenbox since at no point is yours changing the result Apr 08 23:19:25 mu-tiger but how does he know? Apr 08 23:19:32 Greenbox anything multiplied by even is even Apr 08 23:19:36 Greenbox but not everything against odd is odd Apr 08 23:19:42 mu-tiger that char didn't take the even number? Apr 08 23:19:43 Greenbox he doesn't need to Apr 08 23:19:51 Greenbox as he said, there are 2 cases Apr 08 23:19:58 Greenbox and it depends on what char has, not you Apr 08 23:20:17 Greenbox in a way, you could use what your number is to predict the result Apr 08 23:20:26 Greenbox but unless you can guarantee his number is the opposite type of yours Apr 08 23:20:29 Greenbox there is no way to know Apr 08 23:20:41 mu-tiger but he said char had odd i had even Apr 08 23:20:53 Greenbox look at case 1 then Apr 08 23:20:57 Greenbox <qwertydawom> Mu_even * even + Ch4r_odd * odd = odd Apr 08 23:24:06 qwertydawom so, mu, let's take an example : Apr 08 23:24:30 qwertydawom you choose : 6 Apr 08 23:24:35 qwertydawom Ch4r : 7 Apr 08 23:24:44 qwertydawom then : Apr 08 23:24:49 qwertydawom you : 2 Apr 08 23:24:59 qwertydawom Ch4r : 3 Apr 08 23:25:09 mu-tiger k Apr 08 23:25:15 qwertydawom 6*2 + 7*3 = 33 --> odd Apr 08 23:27:12 qwertydawom ok, so, other example : Apr 08 23:27:39 qwertydawom you choose : 5 Apr 08 23:27:46 qwertydawom Ch4r : 4 Apr 08 23:27:49 qwertydawom then : Apr 08 23:27:54 qwertydawom you : 2 Apr 08 23:28:01 qwertydawom Ch4r : 3 Apr 08 23:28:12 qwertydawom 5*2 + 4*3 = 22 --> even Apr 08 23:28:44 qwertydawom and, in both cases, you see that the sum's evenness/oddness is the same as Ch4r's first number :) Apr 08 23:29:00 qwertydawom Ch4r : 7 -> odd --> 3 -> odd Apr 08 23:29:10 qwertydawom Ch4r : 4 -> even --> 22 -> even Apr 08 23:29:15 mu-tiger yeah Apr 08 23:29:17 mu-tiger ok Apr 08 23:29:23 qwertydawom so, you got it now? :) Apr 08 23:29:29 mu-tiger kinda Apr 08 23:29:35 mu-tiger i need to play with it in my own time Apr 08 23:29:37 mu-tiger ty Apr 08 23:29:38 qwertydawom k ;) Apr 08 23:30:13 qwertydawom Well, this latin quote will take you back to a known country mu ;) : Apr 08 23:30:25 mu-tiger lol Apr 08 23:30:34 qwertydawom "Numero deus impare gaudet." (by Virgilius) Apr 08 23:31:43 qwertydawom it means : Divinity likes odd number. Apr 08 23:32:16 mu-tiger hrm Apr 08 23:32:31 qwertydawom deus -> god Apr 08 23:32:37 qwertydawom gaudet -> likes Apr 08 23:32:41 qwertydawom impare -> odd Apr 08 23:32:47 qwertydawom numero -> number Apr 08 23:32:47 qwertydawom :) Apr 08 23:34:04 qwertydawom ok? Apr 08 23:34:29 mu-tiger yes Apr 08 23:34:49 mu-tiger i was actually thinking about the "holy" numbers, 3, 7, 9 Apr 08 23:34:53 mu-tiger go on pls Apr 08 23:35:16 qwertydawom alright :) Apr 08 23:35:43 qwertydawom So, a quick glance at binary, and then, we'll visit your kingdom, philosophy. ;) Apr 08 23:36:15 qwertydawom So, Ch4r, what are the two symbols in binary? (;P) Apr 08 23:36:26 Ch4r lol Apr 08 23:36:27 Ch4r 0, 1 Apr 08 23:36:32 qwertydawom yay! haha Apr 08 23:36:35 Ch4r :P Apr 08 23:36:47 qwertydawom so, yeah, 0 or 1, false or right Apr 08 23:37:18 qwertydawom now, what's about binary's history? Apr 08 23:37:25 qwertydawom well, the binary system Apr 08 23:37:46 qwertydawom was invented in Europe by Leibniz (a mathematician, philosopher...) Apr 08 23:38:09 qwertydawom refering to the chinese book "Ye-Kim" Apr 08 23:38:28 qwertydawom which was written in China around 25 centuries BC Apr 08 23:38:52 qwertydawom Leibniz associated 0 with "nothing" and 1 with "God" Apr 08 23:39:50 * Ch4r removes channel operator status from Ch4r Apr 08 23:39:50 qwertydawom He found a mystical(yay, mysticgoose :p) meaning to the fact that all the numbers could be created from "nothing" and the "unity". Apr 08 23:40:23 qwertydawom Obviously, the success of the binary system is due to the developement of computers. Apr 08 23:40:53 qwertydawom Now, what about binary coding? Apr 08 23:41:05 qwertydawom example : what's 315 in binary? Apr 08 23:41:14 bonusbug .o0(hmm thats why he made this amazing Leibnitz cookies ? ... ;) Apr 08 23:41:43 dDevil 100111011 ;) Apr 08 23:41:53 Ch4r 010000100110100101101110011000010111001001111001001000000110100101110011001000000110110001100101011001010111010000100001 ;) Apr 08 23:42:04 qwertydawom hahaha Apr 08 23:42:05 dDevil Psh, sif. Apr 08 23:42:09 qwertydawom dDevil is right :) Apr 08 23:43:27 qwertydawom and Ch4r's statement is true too :) Apr 08 23:43:31 Ch4r :D Apr 08 23:43:44 dDevil :\ Apr 08 23:43:55 mu-tiger one is ascii and the other is uhm Apr 08 23:43:55 qwertydawom Ok, so, one question, dDevil, did you convert it in your head? Apr 08 23:44:04 dDevil Yesm. Apr 08 23:44:09 qwertydawom good :) Apr 08 23:44:15 qwertydawom which method did you use? Apr 08 23:44:33 dDevil I learnt it by maknig a table Apr 08 23:44:44 dDevil 8 4 2 1, etc Apr 08 23:45:04 qwertydawom Ok, riftor's method maybe? (http://www2.binaryuniverse.net:81/tutorials/binary.txt) Apr 08 23:45:05 dDevil Then, if 256 can go in 315 Apr 08 23:45:13 qwertydawom ok, that's it Apr 08 23:45:19 dDevil = 1 Apr 08 23:45:19 dDevil Ja. Apr 08 23:45:29 dDevil I'm not too good at explaining, sorry :P Apr 08 23:45:33 qwertydawom well, there's also the method of successive divisions. :) Apr 08 23:45:45 qwertydawom let me show you with this example :y? Apr 08 23:46:11 qwertydawom 315/2 -> 157 with a remainder of 1 Apr 08 23:46:39 qwertydawom 157/2 -> 78 with a remainder of 1 Apr 08 23:46:45 dDevil Oooh. Apr 08 23:46:50 qwertydawom 78/2 -> 39 with a remainder of 0 Apr 08 23:46:51 Rolapepsi oh cool, you're teaching modulo now Apr 08 23:47:12 qwertydawom 39/2 -> 19 with a remainder of 1 Apr 08 23:47:25 qwertydawom 19/2 -> 9 with a remainder of 1 Apr 08 23:47:36 qwertydawom 9/2 -> 4 with a remainder of 1 Apr 08 23:47:47 qwertydawom 4/2 -> 2 with a remainder of 0 Apr 08 23:47:58 qwertydawom 2/2 -> 1 with a remainder of 0 Apr 08 23:48:11 qwertydawom now, read the remainders backwards :) Apr 08 23:48:15 Rolapepsi The range of any number modulus x is 0 -> (x-1) Apr 08 23:48:41 qwertydawom (including the "1" of 2/2) Apr 08 23:49:22 qwertydawom and you get : 100111011 :D Apr 08 23:51:18 qwertydawom ok Apr 08 23:51:30 bonusbug (btw this works with every base (2,8,16 or even 3,56,7 .. or whatever) Apr 08 23:51:53 qwertydawom indeed :) Apr 08 23:53:06 qwertydawom now, you may have noticed that this logic principle is Boole's one ;) Apr 08 23:53:30 qwertydawom and.. let's move to philosophy! :) Apr 08 23:55:01 qwertydawom We'll deal with manichaeism. qwertydawom Manichaeism is a conception that divides everything into two parts. qwertydawom Where one is entirely considered with favor, and the other one is completely rejected. qwertydawom If you want to know more : http://en.wikipedia.org/wiki/Manichaeism . qwertydawom duality in philosophy qwertydawom we can also see it if we consider the two following notions : qwertydawom the duality between pleasure and ... ? mu-tiger pain qwertydawom indeed :D qwertydawom The brain is not a computer. qwertydawom He is not functioning as a (knowledge) network administrator, of the memory, or of the relations with the world. qwertydawom The brain is entirely built on the opposition principle : qwertydawom a constant fight between antagonist systems. qwertydawom The couple pleasure/pain can't be separated.A 18:16 <@qwertydawom> It is directed by the neurotransmitters, little moleculas who transmit the messages from one neuron to an other. :) 18:17 <@qwertydawom> Neurotransmitters : 18:18 <@qwertydawom> BAD : serotonin 18:18 <@qwertydawom> GOOD : dopamine 18:21 <@qwertydawom> Well, in fact, it's a bit more complex than that. :P 18:21 <@qwertydawom> There are more than 120 neurotransmitters.. 18:22 <@qwertydawom> So, well, this leads us to the following philosophical question : 18:22 <@qwertydawom> "Is pleasure necessarily related with pain?" 18:23 <@qwertydawom> while, at first sight, you may think "um.. no, when there's pleasure.. no pain...", if you think a bit more 18:23 <@qwertydawom> you may arrive to the conclusion that, indeed, where there's pleasure, pain's not far... 18:23 <+mu-tiger> like scratching an itch 18:24 <@qwertydawom> yep 18:26 <@qwertydawom> and, a philosophy who's (those days) particularly appreciated 18:26 <@qwertydawom> mu, if I say "yin and yang", you answer ... philosophy ? :) 18:26 <+mu-tiger> yes 18:26 <+mu-tiger> definitely 18:27 <+mu-tiger> now, zen is a bit tricky 18:28 <+mu-tiger> (for the western mind) 18:28 <@qwertydawom> indeed 18:29 <@qwertydawom> and, well, one should know that (although most people think the contrary) : 18:29 <@qwertydawom> yin&yang is not good&bad 18:30 <+mu-tiger> that's right 18:30 <+mu-tiger> nor is it really a duality 18:30 <+mu-tiger> but two sides of the same coin 18:31 <@qwertydawom> yes :) 18:33 <@qwertydawom> but we have that : Yin <-> contracting 18:33 <@qwertydawom> Yang <-> expanding 18:34 <@qwertydawom> Yin : moon / Yang : sun 18:34 <@qwertydawom> so, yeah, that's the "two sides of the same coin" 18:35 <@qwertydawom> also, we associate Yin with the woman, and Yang with the man. :) 18:36 <@qwertydawom> Now, let's have a look at the South-Korean flag 18:36 <@qwertydawom> http://www.sfu.ca/~sbaea/KFlag.JPG 18:36 <@qwertydawom> what's the meaning of these symbols? 18:37 <+mu-tiger> it's the yin yang and the i ching hexagrams for 18:37 <+mu-tiger> uhm 18:37 <@qwertydawom> yep :) 18:37 <+mu-tiger> i dunno, heaven and earth? 18:37 <@qwertydawom> up in red: yang (sun) 18:37 <+mu-tiger> fire and water? 18:37 <@qwertydawom> blue : yin (sea) 18:37 <+mu-tiger> xD 18:38 <@qwertydawom> this represents the symbol of "moving", of "equilibrium" and the harmony of "infinity sphere". 18:39 <@qwertydawom> On the sides, there are "trigrams"(Pa-Kua), with a sort of diagonal symmetry. 18:39 <@qwertydawom> Each one of them represents one of the four fondamental elements : 18:40 <@qwertydawom> upper left hand : air 18:41 <@qwertydawom> bottom right hand : earth 18:41 <@qwertydawom> bottom left hand : water 18:42 <@qwertydawom> so, upper right hand is ... ? :) 18:42 <@qwertydawom> sorry 18:42 <@qwertydawom> bottom left hand is fire 18:42 <@qwertydawom> hence, upper right hand is water 18:43 <@qwertydawom> so, now, let's "invent" binary trigrams 18:43 <@qwertydawom> so, we say that a "full line" is 1 18:43 <@qwertydawom> and a "cut line" is 0 18:44 <+mu-tiger> k 18:44 <@qwertydawom> we have : 18:44 <@qwertydawom> (I do all possibilities) 18:44 <@qwertydawom> 000 -> air 18:45 <@qwertydawom> 001 -> steam 18:45 <@qwertydawom> 010 -> fire 18:45 <@qwertydawom> 011 -> thunder 18:45 <@qwertydawom> 100 -> wind 18:45 <@qwertydawom> 101 -> water 18:45 <@qwertydawom> 110 -> mountain 18:45 <@qwertydawom> 111 -> earth 18:46 <@qwertydawom> on the korean flag, we have : 18:46 <@qwertydawom> 000, 010, 101 and 111. 18:46 <@qwertydawom> now, if we convert them to decimal, we get : 18:46 <@qwertydawom> 000 = 0 18:46 <@qwertydawom> 010 = 2 18:47 <@qwertydawom> 101 = 5 18:47 <@qwertydawom> 111 = 7 18:47 <@qwertydawom> so that, every diagonal of the flag has a sum equal to 7 :) 18:47 <+mu-tiger> ok 18:47 <@qwertydawom> heavan + earth : 0 + 7 = 7 18:47 <@qwertydawom> water + fire : 2 + 5 = 7 18:48 <@qwertydawom> 5 + 2 actually 18:51 <+mu-tiger> well 18:51 <@qwertydawom> So, with this eastern philosophy, our lecture will end. :)
