|---|---|---|
| wrldpc | I met a lady who does fashion design and I want to impress the pants onto her. | 02:24 |

| kanzure | http://en.wikipedia.org/wiki/Nondimensionalization | 07:37 |
| kanzure | "Examples of recovering characteristic units | 07:39 |
| kanzure | A variety of systems can be approximated as either first or second order systems. These include mechanical, electrical, fluidic, caloric, and torsional systems. This is because the fundamental physical quantities involved within each of these examples are related through first and second order derivatives." | 07:39 |
| kanzure | wtf? | 07:41 |
| kanzure | http://en.wikipedia.org/wiki/System_equivalence | 07:41 |
| kanzure | why do I see "effort" and "flow" showing up here | 07:41 |
| kanzure | "The number of free parameters in a nondimensionalized form of a system increases with its order. For this reason, nondimensionalization is rarely used for higher order differential equations. The need for this procedure has also been reduced with the advent of symbolic computation" | 07:45 |
| kanzure | http://en.wikipedia.org/wiki/Buckingham_π_theorem | 07:46 |
| kanzure | "Begin by considering the space of fundamental and derived physical units as a vector space over the rational numbers, with the fundamental units as basis vectors, and with multiplication of physical units as the "vector addition" operation, and raising to powers as the "scalar multiplication" operation: represent a dimensional variable as the set of exponents needed for the fundamental units (with a power of zero if the particular fundamental unit is not present). For instance, the gravitational constant g has units of (distance over time squared), so it is represented as the vector (1, − 2) with respect to the basis of fundamental units (distance,time)." | 07:47 |
| kanzure | can anyone get me this? Buckingham, E. (1915). "Model experiments and the forms of empirical equations". Trans. A.S.M.E 37: 263–296. | 07:50 |
| fenn | system equivalence says 'flow, effort' not 'through, across' | 07:53 |
| fenn | wrldpc: take a gander at openmaterials.org | 07:56 |
| fenn | nondimensionalization is a load of words | 07:56 |
| fenn | i think i function as the heatsink for my laptop | 07:57 |
| faceface | kanzure: look interesting | 08:03 |
| faceface | looks like you need to ask your library | 08:04 |
| faceface | Discovering empirical equations from robot-collected data? http://www.springerlink.com/content/221q465584853531/ | 08:05 |
| kanzure | is that lipson or The Robot Scientist? | 08:08 |
| kanzure | springerlink sucks (when you're not on campus) | 08:08 |
| fenn | BACON and FAHRENHEIT are unusual names for computer programs | 08:13 |
| kanzure | for some reason nondimensionalization seems to mean "just add coefficients to all of your terms in your ODE and then find out which variables within the coefficients you want to set to unity (with each other) first, then do something something something" | 08:15 |

| genehacker | kanzure? | 18:48 |
| genehacker | hello? | 19:08 |
| drazak_ | yo | 19:08 |
| genehacker | http://www.physorg.com/news163076711.html | 19:23 |
| genehacker | heat sink fins that branch all the way down.... | 19:23 |
| kanzure | hi genehacker | 19:35 |
| genehacker | so when are we going to test the filter | 19:35 |
| kanzure | tomorrow is unlikely because fake mom is coming over | 19:36 |
| kanzure | but maybe wednesday | 19:36 |
| kanzure | you can test it if you want | 19:36 |
| genehacker | ok | 19:36 |
| kanzure | but if you need me that's cool too | 19:36 |
| genehacker | also are you located by the fry's? | 19:36 |
| kanzure | no | 19:36 |
| genehacker | ok | 19:36 |
| kanzure | I'm at ben white and lamar | 19:36 |
| genehacker | yeah I know | 19:36 |
| kanzure | fry's is up north | 19:36 |
| genehacker | where's the fab lab again? | 19:36 |
| kanzure | ben white and congress | 19:37 |
| genehacker | ok | 19:37 |
| kanzure | it's within biking distance | 19:37 |
| genehacker | from the university? | 19:38 |
| kanzure | well, maybe | 19:38 |
| genehacker | I'm quite close to the university | 19:38 |
| kanzure | but it's definitely within biking distance of my apartment | 19:38 |
| kanzure | feel free to show up some time | 19:38 |
| kanzure | anime nights are from 1 to 5 on saturday nights | 19:38 |
| genehacker | I'm also not to far from a Japanese style arcade... | 19:38 |
| kanzure | fenn lives here now, so we're scheming up ways to take over the galaxies | 19:39 |
| genehacker | heh | 19:39 |
| drazak_ | kanzure: pm or am? | 19:39 |
| drazak_ | kanzure: well what would else would you do, narf | 19:40 |
| genehacker | how will I know which building the fablab is? | 19:40 |
| kanzure | drazak_: 1 to 5 of Sunday morning. | 19:40 |
| kanzure | genehacker: well I guess I could show it to you some time | 19:40 |
| drazak_ | that's what I thought | 19:40 |
| genehacker | any day this week before thursday? | 19:40 |
| kanzure | uh possibly | 19:40 |
| kanzure | it kind of depends on les | 19:41 |
| kanzure | not so much on me | 19:41 |
| genehacker | anyway I don't have internet access until next tuesday | 19:41 |
| kanzure | I don't know when he's awake or available to open the door | 19:41 |
| kanzure | yikes | 19:41 |
| genehacker | unless I crack wpa2 | 19:41 |
| kanzure | I guess I do have ssh access to some supercomputers on campus | 19:41 |
| drazak_ | lol | 19:42 |
| genehacker | or get some sort of directional antenna to get campus wifi | 19:42 |
| kanzure | genehacker: someone is going to fund my myostatin inhibitors project | 19:43 |
| genehacker | is there anyway I can use a router as a signal repeater, I have two of them. | 19:43 |
| genehacker | the last person to live in my room left some cruft | 19:44 |
| kanzure | search around for info on "meshes" | 19:44 |
| genehacker | who's funding you? | 19:44 |
| kanzure | someone. | 19:44 |
| kanzure | there's about $5k to $10k USD available | 19:45 |
| genehacker | whoa | 19:45 |
| genehacker | do they think you are an actual lab? | 19:45 |
| drazak_ | I wonder if I can get someone to fund microfluidics sequencer | 19:45 |
| drazak_ | kanzure: link to your set of microfluidics papers? | 19:45 |
| kanzure | genehacker: no, he knows who I am | 19:45 |
| kanzure | drazak_: http://heybryan.org/books/microfluidics/ | 19:46 |
| kanzure | uh | 19:46 |
| drazak_ | ty | 19:46 |
| kanzure | drazak_: http://heybryan.org/books/papers/microfluidics/ | 19:46 |
| kanzure | I fail | 19:46 |
| genehacker | how long does your paper dump take to download? | 19:46 |
| kanzure | forever | 19:46 |
| kanzure | I suggest downloading the zip file | 19:46 |
| genehacker | shit | 19:46 |
| genehacker | where? | 19:46 |
| kanzure | one moment | 19:47 |
| kanzure | http://heybryan.org/books/papers/microfluidics_2009.zip | 19:47 |
| kanzure | 60 MB | 19:47 |
| drazak_ | thanks | 19:47 |
| kanzure | now, if you want it faster | 19:47 |
| drazak_ | I might download that then expand it on my phone | 19:47 |
| genehacker | ok I got a download accelerator let's do this | 19:48 |
| kanzure | http://sata.serveftp.org/~bryan/papers/microfluidics_2009.zip | 19:48 |
| kanzure | genehacker: use that link instead | 19:48 |
| kanzure | it's at the university so it will go much more quickly | 19:48 |
| drazak_ | kanzure: are microfluidics devices usually on SiO2? | 19:49 |
| genehacker | I'm at the university | 19:49 |
| kanzure | genehacker: then you should definitely use the sata.serveftp.org link | 19:49 |
| kanzure | drazak_: PDMS. | 19:49 |
| genehacker | it's like silicone | 19:49 |
| genehacker | hmmmm... | 19:49 |
| drazak_ | kanzure: can you connect F to them? | 19:50 |
| kanzure | fluorine? | 19:50 |
| drazak_ | yes | 19:50 |
| kanzure | not sure | 19:50 |
| drazak_ | I want it for it's ability to make H-bonds | 19:50 |
| kanzure | SU-8 is also popular | 19:51 |
| drazak_ | I bet you could flouridate the C's | 19:51 |
| genehacker | what are you trying to do drazak? | 19:53 |
| kanzure | here's a backup of all papers up to 2009-04-08: http://sata.serveftp.org/~bryan/papers/papers-backup-2009-04-08.zip | 19:53 |
| kanzure | it's 744 MB, so be careful | 19:53 |
| kanzure | oh | 19:54 |
| kanzure | here's a better microfluidics archive, genehacker | 19:54 |
| kanzure | http://sata.serveftp.org/~bryan/papers/microfluidics.tar.gz | 19:54 |
| kanzure | this one is 237 MB in size | 19:54 |
| kanzure | and more recent than the other one | 19:54 |
| genehacker | blast | 19:55 |
| genehacker | 17 minutes left on this one | 19:55 |
| genehacker | 15 minutes | 19:55 |
| kanzure | how quickly is it going? | 19:55 |
| genehacker | about 50 kb/s | 19:56 |
| kanzure | huh that sucks | 19:56 |
| kanzure | have you tried plugging into a wall? | 19:56 |
| genehacker | no | 19:57 |
| genehacker | no wall plug | 19:57 |
| genehacker | hmmm wonder if I could close my laptop and move to the library | 19:57 |
| genehacker | what it's closed? | 19:59 |
| genehacker | hmm downloading slower over here | 20:00 |
| kanzure | are you sure you're using the satalab one not the heybryan.org one? | 20:00 |
| genehacker | I don't know | 20:01 |
| genehacker | first link you posted | 20:01 |
| kanzure | ok, definitely use this one instead: | 20:02 |
| kanzure | http://sata.serveftp.org/~bryan/papers/microfluidics.tar.gz | 20:02 |
| kanzure | you should get a few MB/sec | 20:02 |
| genehacker | I don't think I can open tarballs though | 20:05 |
| kanzure | use winzip or winrar or 7zip | 20:06 |
| genehacker | it's loading fast though | 20:06 |
| genehacker | ok | 20:06 |
| genehacker | it's about 3 minutes | 20:06 |
| kanzure | isn't that better nw | 20:06 |
| kanzure | *now | 20:06 |
| genehacker | yes | 20:07 |
| genehacker | blasted library is closed | 20:07 |
| genehacker | I need to scan some fluidics books | 20:08 |
| genehacker | also how would you like a scan of a robotics and automation book I found sitting in my room | 20:08 |
| kanzure | dunno | 20:08 |
| genehacker | I got a scanner and some free time | 20:09 |
| genehacker | it has some math for designing robots | 20:10 |
| genehacker | done | 20:10 |
| kanzure | have fun | 20:10 |
| genehacker | you might want to read this one alexander bolonkin paper | 20:11 |
| kanzure | I thought you don't do names | 20:11 |
| genehacker | alexander bolonkin = crazy russian physicist | 20:11 |
| genehacker | if what he says is right we could put a car on top of RLM or any building in austin | 20:12 |
| kanzure | by disassembling it and re-assembling it | 20:13 |
| kanzure | simple | 20:13 |
| genehacker | without that | 20:13 |
| genehacker | any building under 1 kilometer in height we could put stuff on | 20:14 |
| genehacker | stuff weighing one tone | 20:15 |
| genehacker | *metric ton | 20:15 |
| genehacker | http://www.aiaa.org/content.cfm?pageid=406&gTable=Paper&gID=27505 | 20:17 |
| genehacker | use the library proxy for this one | 20:18 |
| genehacker | well I'm leaving the wifi coverage area | 20:18 |
| drazak_ | genehacker: make a spot on the side of a tube in a microfluidics device where a nucleoside is favorably attracted to | 20:21 |
| drazak_ | attracted is the wrong word | 20:21 |
| drazak_ | it's favorable for it to stay there | 20:21 |
| genehacker | attached is ok | 20:25 |
| genehacker | quick drazak | 20:25 |
| genehacker | about to leave coverage | 20:25 |
| drazak_ | what do you want to know? | 20:25 |
| drazak_ | it's a dna sequencer | 20:25 |
| genehacker | ok | 20:26 |
| drazak_ | dna is cut by photoactivated exonucleases to nucleosides, and then it moves down a small area, where it finds the place where it's most favorable | 20:26 |
| drazak_ | then, valves are sealed seperating every area of favorability for a different nucleoside | 20:27 |
| -!- Netsplit kubrick.freenode.net <-> irc.freenode.net quits: bryan_, nsh, bkero, faceface, tarbo2 | 20:27 | |
| drazak_ | and then the nucleoside is moved into the detection area | 20:27 |
| drazak_ | where it's detected by a change in light intensity | 20:28 |
| -!- Netsplit over, joins: nsh, faceface, tarbo2, bryan_, bkero | 20:28 | |

| -!- Netsplit over, joins: jm|afk | 20:28 | |
| genehacker | leaving coverage area in | 20:30 |
| genehacker | 5 | 20:30 |
| genehacker | 4 | 20:30 |
| genehacker | 3 | 20:30 |
| genehacker | 2 | 20:30 |
