--- Day changed Mon May 04 2009 00:00 < kanzure-> the alarm sound could be fixed by long headphones 00:00 < kanzure-> a headphone jack shouldn't be too hard to integrate on to it 00:00 < kanzure-> although maybe it would be better if the battery discharges an electric shock 00:16 < ybit> " The Elite has a snooze button, audible and vibrating alarms, is water-resistant,..." 00:16 < ybit> sweet. 00:25 < ybit> now what file format is the data stored in... :) 00:39 < kanzure> http://www.s-ten.eu/scadaonweb/NOTE-units/2002-08-05/NOTE-units.html RDF vocabulary for physical properties, quantities and units 00:39 < kanzure> meh 00:39 < kanzure> http://www.w3.org/TR/mathml-units/ 00:42 < kanzure> http://mathdom.sourceforge.net/ bah doesn't implement the MathML-units subset. 00:43 < kanzure> this sounds like a terrible idea: http://www.aclevername.com/articles/python-webgui/ creating python apps with HTML rendering engines 00:45 < kanzure> er, what? http://empathy.sympy.org/ 00:45 < kanzure> http://3.bp.blogspot.com/_Y5scPLmSvG0/SYnjsGNXnBI/AAAAAAAAAHA/u7QCC2mhzl8/s1600-h/Picture+2.png 02:01 < kanzure-> genehacker: have a few minutes? 02:01 < genehacker> sure 02:01 < genehacker> what is it 02:01 < kanzure-> ok, one moment. 02:02 < kanzure-> basically I have an equation and a diagram and I'm wondering how this author got from one to the other 02:03 < genehacker> what class? 02:03 < genehacker> is it diff-eq? 02:04 < genehacker> you might consider going to tutoring 02:04 < kanzure> http://heybryan.org/books/papers/campbell-dissertation-diagram-thingy.png 02:05 < kanzure> first of all, why would you have 1/k for a spring? 02:05 < kanzure> if k is the spring constant of the spring 02:07 < genehacker> because the spring is acting against it? 02:07 < kanzure> wouldn't that be subtractive? 02:08 < genehacker> don't know 02:08 < kanzure> does the shape of those equations make sense? 02:08 < kanzure> *do the shapes of those equations 02:08 < genehacker> seems like you guys have made some progress though 02:09 < kanzure> ? 02:09 < genehacker> what software is this in? 02:09 < kanzure> lisp 02:09 < kanzure> this was from cambell's July 2000 dissertation 02:10 < kanzure> campbell's 02:10 < kanzure> gah. /me fails at typing tonight 02:20 < kanzure> what's the effect of increasing the radius of the gear? 02:20 < genehacker> more radial displacement of rod 02:21 < genehacker> err less? 02:21 < genehacker> forgot 02:21 < kanzure> ? 02:21 < genehacker> can't think now 02:21 < kanzure> because in this case the theta of a dial-doohicky is being changed by 1/r where r is the radius of the gear 02:21 < kanzure> so a larger radius is going to make a smaller impact. 02:21 < kanzure> just want to make sure this makes sense. so far it doesn't sound like it. 02:24 < genehacker> use geometry 02:27 < kanzure> huh? 02:28 < kanzure> yay. campbell's dissertation included source code at the end. 02:29 < genehacker> rack displacement= arclength 02:29 < kanzure> oh? 02:29 < genehacker> =theta*r 03:10 < kanzure-> so I like how these papers are written, by campbell I mean 03:10 < kanzure-> "for more information on this method, please see Campbell 1998b" 03:10 < kanzure-> *campbell 1998b* 03:51 < genehacker> so are there any books of chemicals with reactions on how to make them 03:51 < genehacker> I want a chemical microfactor 03:51 < genehacker> y 04:09 < katsmeow-afk> i want 10 gallons of anhydrous ammonia 04:16 < kanzure-> I want a meth lab that dissolves within the presence of cop sweat. 04:16 < kanzure-> wait, I don't actually know anybody who has a meth lab 04:17 < kanzure-> what is the type of person who makes a meth lab anyway? 04:17 < katsmeow-afk> profit oriented, a real go getter, someone who takes calculated risks 04:17 < katsmeow-afk> bank presidents, perhaps 04:17 < kanzure-> is there a distribution network for illegal meth lab equipment or something? 04:18 < katsmeow-afk> umm, i doubt it, but possibly 04:18 < genehacker> heh 04:18 < kanzure-> are they that organized? 04:18 < katsmeow-afk> there's illegal nets for everything else 04:18 < kanzure-> guess so 04:18 < genehacker> let's not do meth production 04:18 < katsmeow-afk> i dunno what i'd use meth for, actually 04:18 < kanzure-> just wondering how they do it. 04:18 < katsmeow-afk> i do have a use for the ammonia tho 04:19 < genehacker> they don't do it very carefully 04:19 < genehacker> think harvesting lead batteries for sulfuric acid 04:19 < genehacker> that sort of thing 04:19 < katsmeow-afk> atm, the lead may be more profitable 04:19 < katsmeow-afk> also more restricted by EPA 04:20 < katsmeow-afk> if you pour out a lead acid battery, they get your forlead contamination, not the acid 04:20 < genehacker> I think I might teach myself O chem 04:20 < genehacker> over the summer 04:21 < katsmeow-afk> i wanna make a couple "frosty balls", then praps improve them from that point 04:21 < kanzure-> organic chem? 04:22 < genehacker> the heat based fridge thing? 04:22 < genehacker> yeah 04:22 < katsmeow-afk> water absorber fridge, yeas 04:22 < genehacker> how else am I going to figure out how to synthesize 3,4-(methylenedioxy)acetophenone 04:23 < genehacker> can't find that much info about it on google 04:23 < kanzure-> graph grammars. 04:23 < katsmeow-afk> *if* the things work as advetised, and i can figure a btu rating for them, then how to keep , esentially but not really, one in the solar recycler, and one in duty cooling me 04:23 < kanzure-> genehacker: or retroactive synthesis 04:23 < genehacker> yeah automatic design of microreactors would be great 04:23 < kanzure-> no, I mean of chemical reactions 04:24 < kanzure-> this is like the perfect application 04:24 < genehacker> as I said I want a chemical factory that can make anything 04:24 < kanzure-> lemme see if anyone has written an organic chemistry graph grammar 04:24 < genehacker> well you know the chemical reactions that take place you just use standard reactors 04:24 < kanzure-> huh? 04:25 < kanzure-> did you mean to include an "if" in there? 04:25 < katsmeow-afk> i am thinking a mist of water falling thru the ammonia, and the sent to the solar furnace to get the ammonia out, which is condenced and sent back to the evaporator, with a tank of water as the "flywheel" for the thing 04:25 < genehacker> solar cooling systems are pretty weird 04:26 < genehacker> also ammonia is a basic chemical it's a must for my a chemical microfactory 04:26 < katsmeow-afk> with no sun for a few days, there's still a tank of water and enough ammonia, and with sun or other heat source, the tank of water is processed to remove the ammonia 04:27 < kanzure-> heh. sciXML 04:27 < genehacker> you found one? 04:28 < kanzure-> not yet 04:30 < kanzure-> but maybe you could just make the grammar rules or something 04:30 < kanzure-> since organic chemistry has only like 21 main rules 04:30 < kanzure-> "if you see this, then blah" 04:31 < genehacker> cool 04:31 < genehacker> have you taken O chem? 04:31 < kanzure-> no, but I've read a few books 04:31 < genehacker> http://www.rsc.org/Publishing/Journals/LC/article.asp?doi=b822106e 04:31 < genehacker> hehehehehe 04:31 < genehacker> alkaloid purification 04:32 < genehacker> alkaloids generally tend to have certain effects on humans 04:32 < genehacker> http://www.rsc.org/Publishing/Journals/LC/article.asp?doi=b901790a 04:32 < kanzure-> odd, nobody has done one yet 04:33 < genehacker> tiny distilation column 04:33 < genehacker> 1write one 04:33 < genehacker> 2.??? 04:33 < genehacker> 3. profit! 04:34 < kanzure-> well we could publish it and act like it's important 04:34 < kanzure-> or just use it. 04:35 < genehacker> what would this graph grammar allow us to do? 04:35 < genehacker> explain what a graph grammar is 04:35 < kanzure-> well, do you know the basic organic chemistry reaction mechanisms? 04:35 < kanzure-> there's like 20 of them, right? 04:35 < genehacker> no 04:35 < kanzure-> er? 04:35 < kanzure-> no you don't know them, or no there's not 20? 04:35 < genehacker> I don' t know them 04:35 < kanzure-> http://en.wikipedia.org/wiki/Organic_reaction 04:35 < genehacker> I'll ask my friend who is taking ochem 04:36 < genehacker> tomorrow 04:36 < kanzure-> the basic types are: 04:36 < kanzure-> addition, elimination, substitution, pericyclic, rearraangement, redox 04:36 < kanzure-> *rearrangement 04:36 < kanzure-> so the idea is to automatically come up with a sequence of steps to take some basic chemicals/structures 04:36 < kanzure-> and transform them into some target compound 04:36 < kanzure-> right? 04:36 < kanzure-> using those reaction types. 04:37 < kanzure-> example: http://en.wikipedia.org/wiki/Substitution_reaction 04:37 < kanzure-> see how there's a left-hand side and a right-hand side? 04:37 < kanzure-> that's basically what we encode into the graph grammar rules 04:37 < genehacker> given a compound, given some basic chemicals like CO, CO2, H, B, N? 04:37 < kanzure-> or something, yeah 04:38 < kanzure-> one moment. let me bring in an organic chemist. 04:41 < kanzure-> blah. nevermind. 04:46 < kanzure-> I think that most people are not interested in building up from basic elements and simple compounds because it would be too many steps 04:46 < kanzure-> but if you're designing a microfluidic system automatically or something 04:46 < kanzure-> then it becomes much easier. 04:47 < genehacker> heat transfer is somewhat easier in microfluidic systems I think too 04:47 < genehacker> yeah that's the point 04:47 < genehacker> that's why it 04:47 < genehacker> 'd be microfluidic 04:48 < genehacker> maybe a bit bigger than microfluidic for some slightly decent production rate 04:48 < kanzure-> I saw a full chemical reaction plant in bondgraph form a few months ago in a ppaer 04:48 < kanzure-> paper 04:48 < kanzure-> was pretty neat 04:48 < kanzure-> http://heybryan.org/books/papers/bondgraphs/Bond%20graph%20modelling%20for%20chemical%20reactors.pdf 04:53 < genehacker> wonder if we could make a machine that turns garbage into useful products given energy 04:53 < kanzure-> oh crap, wrong link 04:53 < kanzure-> try this one: http://heybryan.org/books/papers/bondgraphs/Automatic%20Generation%20of%20Bond%20Graph%20Models%20of%20Process%20Plants.pdf 05:06 < kanzure-> hi fenn. 05:17 < ybit> who's read the 'landmark' paper by fritz? "Translating Biomolecular Recognition into Nanomechanics " 05:17 < kanzure> link or it didn't happen. 05:19 < ybit> http://www.sciencemag.org/cgi/content/abstract/288/5464/316 05:22 < kanzure> "Hybridization of complementary oligonucleotides shows that a single base mismatch between two 12-mer oligonucleotides is clearly detectable. " 05:22 < kanzure> eh? 05:22 < ybit> was referenced in: "Nanomechanical biosensors: a new sensing tool " http://ezproxy.una.edu:2062/science?_ob=MImg&_imagekey=B6V5H-4HK5SGC-1-M&_cdi=5787&_user=7166845&_orig=search&_coverDate=03%2F31%2F2006&_sk=999749996&view=c&wchp=dGLbVtb-zSkWA&md5=4b121d7c045bc7c383f075ad84271dda&ie=/sdarticle.pdf 05:22 < ybit> yeah, i haven't figured out how to link properly from within sciencedirect 05:23 < kanzure> heh, you're at home? 05:23 < kanzure> you basically just replace ezproxy.una.edu:2062 with sciencedirect.com 05:23 < ybit> http://dx.doi.org/10.1016/j.trac.2005.09.006 05:23 < kanzure> yep, my replacement scheme worked 05:23 < ybit> sd has a 'cite or link using doi' 05:24 < ybit> ah, yes 05:24 < ybit> that works too 05:24 < kanzure> looks like this is just "sense a chemical reaction by using an AFM tip that has something special attached to it" 05:25 < kanzure> "high-throughput platforms using arrays of cantilevers have been developed for simultaneous measurement and read-out of hundreds of samples" 05:25 < kanzure> er, how does that look 05:26 * ybit needs to familiarize himself with bibliography tools 05:26 < ybit> what about it? 05:26 < kanzure> zotero is what I've been using recently 05:27 < kanzure> just wondering how they are able to squeeze so many cantilevers together 05:27 < kanzure> I guess they can just shine a laser over the surface of cantilevers or something 05:27 < kanzure> and read them one at a time (in rapid succession) 05:27 < kanzure> but that's cheating 05:27 < kanzure> because you need continuous read-out 05:33 < kanzure> oh. a nano-array of nanocantilevers. bah. 07:02 < kanzure> fenn: http://heybryan.org/books/papers/Guiding%20conceptual%20design%20through%20behavioral%20reasoning%20-%20Welch%20-%20Dixon%20-%201994.pdf 07:03 < kanzure> Hi kardan. 07:05 < kanzure> huh. "directed dependencies". (pg 4) 07:05 < kanzure> seems to restrict the type of analytical equation derived from a design though 07:06 < kanzure> so these partials then define how to construct the equation. a positive directional dependency would imply that there's a positive correlation (i.e., 1*k), whereas a negative directional dependency would imply 1/k 07:06 < kanzure> but then what about terms that need to be added or subtracted? 08:16 < kanzure> I think this is my favorite arxiv feed: http://arxiv.org/list/physics.ins-det/recent 08:19 < kanzure> http://arxiv.org/list/physics.ins-det/0610?show=32 08:19 < kanzure> (just getting the URL voodoo magic right) 08:31 < kanzure> heh, AFM + MRI. /me likes physics.ins-det 08:48 < kanzure> Experimental Study of the Acoustic Field Generated by a 50 MeV Electron Beam in Water 15:02 < kanzure> Hi cis-action_ 15:03 < cis-action_> hi! 15:06 < cis-action_> what's up, kanzure 15:06 < kanzure> cis-action_: microorganism playlist http://www.youtube.com/view_play_list?p=B16E0C8E552629DE 15:06 < cis-action_> I have watched a couple 15:06 < kanzure> already? how's that 15:07 < cis-action_> I am curious what the average hobbyist microscopist setup costs 15:07 < kanzure> "not much" 15:07 < kanzure> doesn't intel give away these cheap little plastic microscopes or something? 15:07 < kanzure> the webcam-microscopes 15:15 < cis-action> back up? gah, this coffeeshop wifi is junky 15:20 < kanzure> cis-action: maybe you could work us diybioers a good deal for used microscopes? 15:21 < cis-action> yeah. that would be good 15:28 < kanzure> genehacker: holy shit. have you been going to the ion channel journal club? 17:47 < myelinzar> need to steal the utex.org database 17:51 < myelinzar> http://heybryan.org/books/papers/channeljc/ 17:52 < myelinzar> Measurement of Cantilever Displacement Using a Compact Disk http://heybryan.org/books/papers/Measurement%20of%20Cantilever%20Displacement%20Using%20a%20Compact%20Disk.pdf 17:52 < myelinzar> Monitoring of an atomic force microscope cantilever with a compact disk pickup http://heybryan.org/books/papers/Monitoring%20of%20an%20atomic%20force%20microscope%20cantilever%20with%20a%20compact%20disk%20pickup.pdf 17:59 < myelinzar> http://www.cs.cmu.edu/afs/cs/project/cadet/ftp/docs/CADET.html 17:59 < myelinzar> er? 18:30 < cis-action_> Hey guys, let's invent or appropriate a new phrase 18:30 < cis-action_> the goal is to post a good suggestion here: http://www.michaeleisen.org/blog/?p=296#comments 18:31 < cis-action_> consider http://en.wikipedia.org/wiki/Homeorhesis, http://en.wikipedia.org/wiki/Chreod, and http://en.wikipedia.org/wiki/Phase_space 18:31 < cis-action_> more background: http://en.wikipedia.org/wiki/Spatiotemporal_gene_expression 18:31 < cis-action_> also see http://web.mit.edu/jakebeal/www/Publications/biocompile.pdf - very interesting! 19:11 < kanzure> plastic 19:11 < cis-action_> plastic? 19:11 < kanzure> yes. 19:11 < cis-action_> I was thinking perhaps we could take an analogy from music. 19:12 < kanzure> Plasticity - In physics and materials science, plasticity describes the deformation of a material undergoing non-reversible changes of shape in response to applied forces 19:12 < kanzure> although in this case it is somewhat reversible 19:13 < kanzure> cis-action_: so, apparently it is possible to make a microscope out of a drop of water and a paper clip 19:13 < kanzure> but it has only 2x magnification 19:14 < kanzure> http://bizarrelabs.com/micro.htm 19:14 < kanzure> also see the "table top model" 19:14 < cis-action_> neat 19:14 < cis-action_> would a pinhole also work? 19:15 < kanzure> a pinhole does not magnify. 19:15 < cis-action_> nevermind. 19:15 < kanzure> heh, tested it? 19:15 < cis-action_> uh... what's the difference between focusing and magnification? 19:19 < kanzure> focusing is where light converges on to a single point. you don't want that to happen when you are magnifying 19:20 < kanzure> http://www.rockcastle.org/activities/watermagnifier/watermagnifier.html 19:21 < kanzure> a superhydrophobic surface with a very tiny drop of water would be the best magnifier methinks 19:21 < kanzure> I've been trying to figure out what the largest hysteresis angle is for a superhydrophobic surface and a drop of water 19:22 < kanzure> To use a water-drop lens on something that is not flat on a desk or table, you can make a little loop in a thin wire bent around a stout nail to make a loop. In this loop, you can put a drop of water. You can "waste" many such lenses until you get one whose curvature is just about right. 19:22 < kanzure> "broth lens" heh 19:25 < kanzure> also try it with the water on saran wrap 19:28 < kanzure> water-drop projector, bwahahah 19:30 < kanzure> cis-action_: this is sufficiently cool to warrant your attention. 19:30 < kanzure> http://heybryan.org/books/papers/Water-drop%20projector.pdf 19:32 < kanzure> http://heybryan.org/books/papers/Water-drop%20projector.pdf 19:32 < kanzure> hm. so if you put multiple drops of water in a row, would that increase the magnification? 19:36 < kanzure> hah, yay for halfbakery 19:36 < kanzure> http://www.halfbakery.com/idea/Fly_20eye_20water_20lens 19:36 < kanzure> http://www.technologyreview.com/computing/21449/?a=f An adjustable-focus lens made of two drops of water could be used in small cameras. 19:38 < xp_prg> kanzure did you know blender can export collada format? 19:45 < kanzure> collada is what? 19:48 < kanzure> images of droplet magnifiers 19:48 < kanzure> http://www.flickr.com/photos/lordv/sets/72057594101162264/ 20:02 < fenn> but zone plates do 20:02 < fenn> guh 20:03 < fenn> a pinhole does not focus, it makes an image cone 20:03 < xp_prg> collada is a 3d file format 20:04 < genehacker> so I asked my friend who's taking ochem 20:04 < genehacker> about the reactions 20:04 < genehacker> she says there's about 15 20:05 < fenn> i think the problem with lots of steps in synthesis is that you have to purify each step or else you end up with a bunch of side reaction junk at the end 20:06 < genehacker> btw how sensitive is something that can measure parts per billion concentrations? 20:06 < kanzure> that doesn't sound like much.. considering avogadro's number. 20:07 < genehacker> oh well 20:07 < fenn> werent they making some moon telescope with mostly frozen mercury rotating slowly so as to form a parabola? 20:07 < kanzure> so why don't I see any "capillary tube lens arrays" of droplets? 20:07 < genehacker> anyway, found a cool microfluidic device that we could have that one guy make 20:07 < fenn> ppb is pretty useful for lots of stuff 20:08 < genehacker> a microfluidic gas chromatograph 20:08 < kanzure> ppb? 20:08 < fenn> kanzure: the droplet array would never work 20:08 < kanzure> why's that 20:08 < genehacker> droplet array has been done before 20:08 < kanzure> genehacker: not a 2D array 20:08 < kanzure> a 1D array 20:08 < fenn> too hard to control the focal length 20:08 < fenn> a 1d array? 20:08 < genehacker> a 2d array 20:08 < kanzure> well I'm talking about a 1D array 20:08 < kanzure> ooooooooooooooooooooooooo 20:09 < fenn> the oil lens thing is neat though 20:09 < genehacker> liquid microlens arrays 20:09 < kanzure> genehacker: have you ever used a one-dimensional array? 20:09 < genehacker> no 20:09 < kanzure> god programming classes suck these days 20:10 < genehacker> that sort of array? 20:10 < genehacker> yeah definately 20:10 < kanzure> same thing 20:10 < genehacker> ok so why are you interested in microlenses? 20:11 < genehacker> ppb thing I was talking about was a microfluidic CO2 sensor btw 20:11 < fenn> where are you going to be finding ppb of CO2? 20:12 < genehacker> car exhaust is what they proposed 20:13 < fenn> ummm 20:13 < fenn> car exhause is like 50% CO2 20:13 < genehacker> yeah or something like that 20:13 < genehacker> oxygen or something 20:13 < genehacker> forgot 20:13 < fenn> water 20:13 < fenn> nitrogen 20:14 < genehacker> it was in this book 20:14 < genehacker> http://www.azonano.com/sale.asp?saleID=188 20:16 < kanzure> http://laser.physics.sunysb.edu/~scott/liquid-lens/ 20:16 < genehacker> oh, almost forgot 20:17 < genehacker> so I was thinking about that cheap maskless lithography gene synthesis method that put a projector on a microscope 20:17 < genehacker> so the problem with that is alignment 20:18 < genehacker> to get the chemicals on the microscope slide, you'd have to move the microscope out of focus or the microscope slide from under the microscope 20:19 < genehacker> this means we'd have to align it each time 20:19 < genehacker> which is hard 20:19 < kanzure> that's what the guys did for the microfluidics version 20:19 < genehacker> huh? 20:19 < kanzure> they had this turnable thingy doohickey that rotated the specimen out of the field of view 20:19 < genehacker> that's why some sort of thing that sits on the slide and dispenses chemicals would be nice 20:20 < genehacker> link to turn table thing? 20:20 < ybit> http://www.google.com/hostednews/afp/article/ALeqM5j_fD9Hyb2yHGiXZSFRhpu9BMvWCw 20:21 < ybit> BEIJING (AFP) — Officials in a county in central China have been told to smoke nearly a quarter million packs of locally made cigarettes annually or risk being fined, state media reported. 20:21 < ybit> The Gong'an county government in Hubei province has ordered its staff to puff their way through 230,000 packs of Hubei-produced cigarette brands a year, the Global Times said. 20:21 < kanzure> genehacker: they didn't mention it in the paper other than that they were using it 20:21 < genehacker> argh 20:21 < genehacker> in all these DNA synthesis papers 20:22 < genehacker> they say standard DNA synthesizer or something like that 20:23 < kanzure> it's phosphoramidite synthesis 20:23 < kanzure> did you look at my paper collection? 20:23 < kanzure> http://heybryan.org/mediawiki/index.php/DNA_synthesizer 20:23 < kanzure> http://heybryan.org/books/papers/microfluidics/synthesizer/ 20:24 < kanzure> oops, last link was wrong 20:24 < kanzure> http://heybryan.org/books/papers/microfluidics/synthesis/ 20:24 < kanzure> http://heybryan.org/books/papers/%20In%20situ%20DNA%20synthesis%20on%20glass%20substrate%20for%20microarray%20fabrication%20using%20self-focusing%20acoustic%20transducer.pdf 20:24 < fenn> kanzure: http://www.technovelgy.com/ct/Science-Fiction-News.asp?NewsNum=946 electrowetting lens 20:24 < kanzure> http://heybryan.org/books/papers/In%20situ%20synthesis%20of%20oligonucleotide%20arrays%20by%20using%20soft%20lithography.pdf 20:24 < fenn> supposedly you can actually buy a webcam with one of these lenses in it 20:25 < genehacker> http://www.azonano.com/sale.asp?saleID=188 20:25 < fenn> but it looks pretty straightforward to make 20:25 < kanzure> right 20:25 < kanzure> heh, Dune. 20:25 < genehacker> so we need a flow cell reaction chamer 20:25 < genehacker> *chamber 20:26 < fenn> also check out 'origami optics' (not what you think) 20:27 < kanzure> http://www.popsci.com/files/imagecache/article_image_large/files/articles/origami-lens-1a.jpg 20:27 < kanzure> I do not understand 20:27 < kanzure> what's with the black gloves? 20:28 < kanzure> has there been any study of positional control/stability of falling drops of water from a dripping faucet (etc.)? 20:28 < kanzure> if you have two or more droplets in mid-air on the same axis, lasers might be interesting in that scenario somehow 20:29 < fenn> http://www.jacobsschool.ucsd.edu/uploads/news_release/2007/magick_lens_comparisonLR2.jpg 20:29 < genehacker> electrostatics 20:30 < fenn> not related to ... whatever it is you're doing, but it's still cool 20:32 < genehacker> how do we make the nucleotides for DNA synthesis? 20:32 < genehacker> nevermind 20:32 < genehacker> it's on your page 20:33 < genehacker> found it but don't really understand it 20:33 < genehacker> or at least I think I understand it 20:35 < genehacker> ooops 20:35 < genehacker> I think I found it 20:41 < kanzure> http://www.flickr.com/photos/22652313@N03/3325505361/ 20:41 < kanzure> now just look at it through the other way 20:43 < genehacker> so what are liquid lenses good for? 20:44 < genehacker> could one make some sort of flat binoculars with them, make glasses that are really binoculars 20:44 < kanzure> haha, captain curiosity 20:44 < kanzure> http://www.google.com/url?sa=U&start=11&q=http://www.captaincuriosity.net/science-experiments-light/science-experiments-light-L06/Light_06_oil_water_magnifyer.pdf&ei=v1L_Se7UGYSitwfD87nECg&sig2=Dn9B7VvayhwHlatE3Kk90w&usg=AFQjCNGuIZT7H_KWoUqIlLimoml7OGTSXg 20:45 < kanzure> http://www.projectlabs.com/htmldocs/straw.htm straw chromatography 20:46 < genehacker> hmmm 20:46 < genehacker> could we seperate proteins and stuff? 21:13 < kanzure> with the spiral filter on a nanometer scale, yes 21:13 < kanzure> or with SDS-PAGE 21:14 < kanzure> http://www.portaldoors.org/ 21:14 < kanzure> they want to collaborate with me 21:22 < kanzure> not sure what they do .. 22:00 < kanzure> "The image dissector was invented by Philo Farnsworth, one of the pioneers of electronic television, in 1927" 22:00 < kanzure> haha! image DISSECTOR! 22:44 -!- davidsjo is now known as johndace 22:44 < kanzure-> Hi johndace 22:47 -!- johndace is now known as davidsjolteon 22:52 < kanzure-> heh, jolteon. 22:57 < kanzure-> so I think you could make an image sensor with an array of biotinylated light-gated ion channels. at least for black-and-white image sensors. 23:25 < kanzure-> genehacker: you might want to consider bacteriorhodopsin as playing a role in gene synthesis. 23:25 < genehacker> what? 23:25 < genehacker> you know you can glue bacteria to microchannels and use them as pumps? 23:25 < kanzure-> eh? 23:25 < kanzure-> I haven't seen that yet 23:25 < kanzure-> ref? 23:26 < genehacker> in pressure driven microfluidics 23:26 < genehacker> in the engineering library 23:30 < genehacker> btw, I'm looking for some documentation on a piece of software called working model 23:36 -!- davidsjolteon is now known as davidsjo
