18:48:05 <lament> Taaus: what exactly is an 'invention'?
20:12:51 <Taaus> Well, do you know what a fugue is?
20:18:40 <lament> yes
20:20:18 <Taaus> Okay, well, an invention is similar to a fugue, except that the Comes theme is in the same key as the Dux theme... Does that make any sense? :)
21:17:07 <lament> yes. What a stupid distinction.
21:17:48 <Taaus> Not really.
21:28:31 <lament> The two-part invention #13 starts with two voices.
21:28:40 <lament> If we're into hair-splitting, that doesn't look at all like a fugue to me.
21:29:26 <Taaus> Umm... Maybe that's because it's an invention?
21:30:56 <lament> if, like you said, the only difference is that the second theme is in the same key, then it's not an invention, either
21:31:55 <Taaus> Heh.. So you're claiming that none of Bach's fugues start with two voices?
21:33:48 <lament> I'm not claiming that.
21:34:00 <lament> I'm claiming that they shouldn't.
21:34:38 <lament> don't fugues absolutely have to begin with one voice?
21:35:11 <Taaus> No. The vast majority does, though.
21:38:55 <lament> Yes _all_ fugues have the second theme in the dominant?
21:39:06 <lament> that doesn't sound right :)
21:39:20 <Taaus> You're right... The 'Yes' sounds out of place in that sentence.
21:42:18 <lament> s/Yes/Yet
21:42:25 <lament> And it _still_ doesn't sound right :)
21:43:14 <Taaus> I'm pretty sure all fugues have the comes theme initially appearing in the dominant. 
21:46:16 <Taaus> If not, there would be no way of distinguishing fugues and inventions ;)
21:46:29 <Taaus> (As an example, that is)
21:46:41 <lament> I don't think so (about the dominant)
21:46:56 * Taaus decides _not_ to mention the Sinphonias.
21:46:56 <lament> http://jan.ucc.nau.edu/~tas3/fugueanatomy.html
21:48:26 <Taaus> Gimme examples, not webpages :)
21:49:10 <lament> no!
21:49:24 <lament> I'll just assume that guy knows what he's talking about
21:49:28 <lament> mostly because he agrees with me
21:49:42 <lament> also because his animated WTC is awesome
21:49:51 <Taaus> *phew* That means I won't have to change my view of you... :X
21:50:08 <lament> well, it _is_ awesome.
21:50:33 <lament> do you know anything about cellular automaton 90?
21:50:56 <Taaus> Nope... Do you reckon there may be something about it in NKS?
21:51:10 <lament> perhaps
21:51:24 <Taaus> Well, I'll go check.
21:51:32 <lament> See, rule 90 has an extremely awesome property of reversing the state
21:51:36 <lament> (see yesterday's log)
21:51:51 <lament> But I didn't find anything about this on Wolfram's site.
21:51:54 <lament> Or anywhere else.
21:51:56 <Taaus> I noticed it :)
21:51:59 <Taaus> It's cool.
21:52:50 <lament> Perhaps Wolfram never found it becasue he's dealing with 'real' automata with unbounded states
21:52:58 <Taaus> Urgh... NLS... Painfully... Heavy...
21:53:00 <Taaus> *NKS
21:53:03 <lament> haha
21:53:07 <lament> Is it at least good?
21:53:17 <lament> All I know about it is from the /. review.
21:53:18 <Taaus> Not really. He's quite full of himself.
21:53:57 <Taaus> lol... Rule 90 has tons of references in the index.
21:54:15 <asdsa> i dont under what going on under  this channel
21:54:24 <asdsa> i dont understand what going on under  this channel
21:54:26 <asdsa> it's why i like it 
21:54:29 <asdsa> =)
21:58:30 <lament> Taaus: page 260, i guess
22:00:28 <Taaus> Hmmm...
22:01:11 <lament> interesting. The most interesting CA are 30,60,90,110,150.
22:01:33 <lament> all divisible by ten, all but one divisible by 30
22:07:23 <Taaus> I can't find anything about Rule 90 producing reversed patterns...
22:08:25 <lament> not even on page 260!
22:08:37 <Taaus> Especially not on page 260.
22:09:10 <Taaus> Heh... It just dawned on me that I have the New Grove Dictionary of Music... Maybe I should look up fugue and invention there :)
22:21:16 <lament> Fugue, n: see Invention
22:21:45 <Taaus> lol
22:23:37 <lament> Somebody on the esolang can't find anything about Thue.
22:24:34 <Taaus> I noticed. I wonder what's happened to Catseye.
22:25:21 <lament> stupid catseye.
22:27:58 * lament posts on comp.theory.cell-automata about rule 90
