1 #+title: Big List O' Ideas2 #+author: Robert McIntyre3 #+email: rlm@mit.edu4 #+description: list of ideas from the last ~ 7 years5 #+keywords: aurellem ideas half-baked random6 #+SETUPFILE: ../../aurellem/org/setup.org7 #+INCLUDE: ../../aurellem/org/level-0.org8 #+babel: :mkdirp yes :noweb yes :exports both10 * Ideas12 This is a list of all the ideas I've had that I felt like writing down13 for the past ~ 8 years. Some of them could be practical inventions and14 are "just" waiting the that 95% perspiration to bring them to15 fruition, some are ideas for science fiction, and some are simple16 observations. Some are really only for my own personal notes and are17 not meant to be comprehensible. They are arranged roughly in reverse18 chronological order, with the most recent ideas at the top of the19 list. The ones at the bottom of the list are heavily influenced by my20 time at MIT.22 If you find some of these interesting and would like to collaborate on23 them with me or discuss them in more detail, I'd love to hear from24 you. You can email me at ideas@aurellem.org.26 If you want to use one of these ideas as your own and run with it,27 please feel free. I'd love to hear about it if you do.29 #+begin_quote30 There's no end to what a man can accomplish if he doesn't care about31 getting credit.32 #+end_quote34 - chaos lock :: The "arrow of time" points in the direction of35 increasing entropy. The time evolution of chaotic36 systems depend exquisitely on their initial state. If37 you take a measurement of a chaotic system at any38 given point of time, you can evolve that system39 backwards or forwards based on your measurement. So40 let's say you start the chaotic system in a VERY low41 entropy state, then let it run for a while, then take42 a measurement with some uncertainty. Your43 measurement is pretty good, but obviously not44 PERFECT. If you evolve the chaotic system back in45 time, then you will see that you don't really reach46 a state with low entropy an hour before (the entropy47 is easy to measure with surrogates like alignment,48 etc). So use this technique to SEARCH for a more49 accurate measurement! This potentially can give you50 many more orders of magnitude than you could get alone51 just using an instrument. Sometimes it will give you52 bad results, the the odds of it doing that are53 infinitesimal, and you can just measure a couple of54 times.56 - cryo-evolution :: perhaps there would be a way to rapidly evolve a57 symbiotic bacterial organism that could protect58 human tissues from freezing damage.60 - suicide parasite :: sometimes, people kill themselves for no good61 reason. We often explain this with things like "hidden62 depression" or we say that they had something like chronic jaw or63 back pain. I think that smells of rationalization. I don't buy64 it. I propose that in many suicide cases there is a disease that65 causes the suicidal behavior. We already know that certain66 parasites have mind-bending properties in other animals, even67 mammals like mice. It's not much of a stretch to imagine a68 parasite that causes suicides in humans. Some problems:69 - What does the suicide parasite get out of it? :: This might be70 answered by the whole thing being a glitch caused by71 cross-species contamination. Toxoplasma works this way.72 - What predictions does a disease model make :: suicide should73 be more common among people who share a contagion74 vector. There should be suicides that don't make any75 sense : people who weren't really depressed, who had no76 reason to kill themselves. People who have killed themselves77 should have a higher incidence of some unknown parasite in78 their brains.80 - domestic insects :: People should eat more bugs because they're much81 more efficient, so why not do some major domestication research82 to make very appealing bugs?84 - birth-clones :: What if each person was intentionally split at birth85 into a normal embryo and a few "backup" cells which86 is then frozen. The backup cells are created just87 the same way as natural identical twins. The backups88 can be used to regenerate organs. etc. Also, it89 would be a good sci fi concept, because you could90 have a culture where people reward people who were91 especially awesome are "reborn" from their92 backups. Imagine having a young Bach every93 generation, etc.95 - pronuncation guide :: a simple webpage where you type in a word and96 it returns a simpe, English sentence describing exactly how to97 pronounce the word. For people who don't want to learn IPA.99 - cortex-search :: use the repertoire of actions learned to limit the100 search space of possible actions.102 - learning to teleport :: scifi idea, this is a story about a person103 who is struggling with his/her society's ideas about104 teleportation. It's considered a fundamental part of being a105 member of that society (after all, the difference between animals106 and humans is that humans are creatures of pure information while107 animals are burdened with base matter, "that's how you travel the108 stars, etc") Humans are born normally, grow up, and then109 eventually transcend via destructive upload. Analogies to jumping110 off a diving board into a pool (which I simply /could not do/ for111 a long time), etc.113 - no-float-ice :: cup that has cross beams at the bottom where ice114 forms. Then when you drink liquid from the glass,115 the ice stays at the bottom and doesn't hit your116 lips. For bars and fancy things.118 - bitcoins for immigrants :: A common case with Mexican immigrants119 (illegal or not) is that they want to send money they've earned120 in the US back to their families in Mexico. They currently do this121 through things like Money Gram or Western Union, and they get122 fleeced in the process with fees. Bitcoin could greatly reduce123 the cost of sending money from America to Mexico, but I don't124 believe that it's currently used for that among Mexican125 immigrants currently due to lack of knowledge. I bet you could126 set up physical locations like those obnoxious Western Union huts127 in places like Texas, Arizona, etc, and greatly undercut128 them. Or, perhaps some educational seminars about bitcoin might129 be in order. There's some money to be made there because there is130 great demand, and it's a good thing to boot!132 - reverse eye-tracking :: A painting that is actually a digital screen133 with a camera. It records people's eye tracks permanently. It's134 "artistic" because paintings are normally these things that you135 look at without changing, but this one is changed the second you136 look at it, recording where /you/ looked forever for others to137 see. Make it be a painting of a woman and see the trolling as the138 breasts and groin area light up with interest from all the males139 passing by.141 - smart toilets :: Instead of using indirect measures like infrared142 detectors of the presence of a person, use computer143 vision to directly measure whether the toilet needs144 to be flushed. I think a lot of things will end up145 going this way as we get better computer vision.147 - validate chemopreservation :: chemopreservation is difficult to148 validate because it destroys the functionality of a brain, and149 brain simulation will take a long time to mature as a150 technology. However, one very powerful way to validate151 chemopreservation would be to have a person/animal learn152 something with high complexity such as a number or the solution153 to a maze, or a flashbulb memory. Then you preserve their brain154 chemically, slice it up, and read /that specific memory/ from the155 detailed brain scan. Much more difficult, but much more doable.157 - candy screw :: edible candy screw with candy nuts that you can screw158 as well.160 - better bibliography :: when writing a thesis or paper, have the161 bibliography not just be an opaque list of resources, but have it162 be a list of /summaries/ and /qualities/ that each paper has in163 the context of the paper being written. When examining a164 bibliography, I want to know if reading the papers in the165 bibliography are worth my time, and I also am probably also166 interested in exactly the things that are being discussed in the167 paper I'm reading. The bibliography is the perfect place to168 provide information about the referenced papers from the169 author's perspective. I will use this biographic form in my own170 thesis.172 - digital inter-library loan :: libraries at universities already do173 inter-library loans for books, so why not do the same for access174 to stupid paywalled digital papers? All the universities could175 allow access to articles for registered students to all the files176 available through any participating university. This could be177 achieved by sending requests through proxies at participating178 universities. Each university would decide who at the university179 can access the proxy network. Access to the proxy network could180 be made easy using something like http://libx.org/.182 - chess visual :: to show the vast size of the game trees considered183 by computers, show two people playing chess in a184 void. They are floating in space, and there is a185 simple chess board between them. Then, as they play,186 the game tree's they are considering are drawn187 behind him. The root of the tree starts centered in188 their heads or whatever they use to think, and the189 tree grows out from behind, never crossing the190 dividing plane between the two players. Each191 player's tree is a different color. As they grow,192 there are animations for pruning, etc. Eventually,193 they look like the hemispheres of a brain, wings,194 etc. A human's tree might occasionally have a long195 chain, while the computer tree would be more196 uniform. You could compare deep blue and a modern197 laptop. Use actual data when fighting two computers!199 - time verification :: some standard way to verify that some piece of200 data was recorded at a specific time. Might involve a time201 server, a key for each time period, something like that.203 - tamper proof gold bars :: [[http://www.tungsten-alloy.com/gold-plated-tungsten-alloy-bar.html][this site]] offers gold plated tungsten bars204 as "novelty" items. One reason to prefer coins is because they205 are much harder to counterfeit because there is less surface area206 to mass ratio. However, gold bars are still a great design207 because they can hold a lot of value in a small space. A gold bar208 could be given the same protections (and more) that gold coins209 have to offer by changing it into a "gold book", which would have210 hundreds of "pages" of gold bound together. This could be211 implemented with multiple steel rods going through the book which212 can be removed, or some more classier mechanism for holding the213 pages. The point is that the bar can be EASILY subdivided (and214 people would perform this test before buying), thus guaranteeing215 it's authenticity.217 - aurellem shirt :: I should make an aurellem star symbol tee-shirt.219 - touch vision :: inspired by GelSight, I want to reexamine cortex and220 see if I could implement touch as a very low range221 form of vision.223 - high school science :: this is a lesson in scientific ethics. The224 goal is to calculate /g/, the local gravitational225 acceleration. The students are told that the textbook says it's226 /exactly/ 9.81 before they start the experiment. See how they227 doctor their results to get closer to the textbook value. It's228 neat because for any given school, /g/ is probably *not* exactly229 equal to 9.81, because that is just an average!231 - opencourseware subtitles :: there are ladies who type up lectures232 while they are being given. These recordings should be kept and233 given to OCW for subtitles. If the timestamps of keys are234 recorded, then it is easy to make subtitles.236 - screen locking timing :: you use your computer camera to see if you237 are sitting in front of the computer. If you are, then the screen238 will never lock. If you are, then the screen will lock with a239 30-40 second timeout. It's an extension of using inactivity to240 initiate the countdown, just with more information.242 - mirror toilet :: a toilet with a square basin made or mirror instead243 or porcelain. That way, you can see how good of a244 wipe job you have done / watch how your excretion245 system works.247 - test dummies :: why don't we clone anencephalic humans and use then to248 test /in vivo/ human organ systems and drugs? It249 would be ethical as long as there are women who are250 willing to host the clones, and it would be a251 tremendous resource for studying the human body. I252 see nothing wrong with it morally, since no one is253 suffering, and it stands to save many lives throughout254 more advanced technology.256 - X-ray telepresence :: given that a doctor is operating on a patient257 via telepresence, one cool things you can do is shine X-rays into258 the patient to view the insides during real time. If the system259 was coupled with a Bayesian model of the layout of the structure,260 and the x-rays were only fired whenever the uncertainty of the261 model reached a certain threshold, then the radiation damage262 and surgery risk could be minimized.264 - superfluid vascular system :: I wonder what would happen if you265 replaced the blood in a human with a superfluid. What would the266 physical dynamics be? Would the superfluid flow through the267 vasculature, or would it ignore it and travel through the cells,268 or something else entirely. Since superfluids need to be cold to269 retain their superfluidity, how would the dynamics change during270 perfusion of a superfluid, where the fluid gains and looses271 superfluidity as it goes deeper into the body and is cooled by272 superfluid from upstream. In summary there are two things to273 simulate 1.) replace all blood in human with superfluid274 instantly. 2.) perfuse superfluid into human.276 - projective guessing :: I think that we read and see things by277 making a really good guess about what we're expecting to see,278 and then searching for our guess in what we see. If it really279 doesn't match, then we start to make more guesses / analyze the280 image from first principles, but most stuff is projective281 guessing.283 - Intestinal flora maintenance :: why not inoculate babies at birth284 with "ideal" gut flora instead of whatever bullshit they285 naturally get, thus giving them optimal digestive/nutrient286 extraction capabilities. Might also be able to make their farts287 not stink for life, too.289 - server culture : mirrors :: make a distributed system where people290 can mirror the websites of people they like -- essentially cover291 the server costs of favored websites. This could make popular292 websites run at no cost. The system would require that the293 mirrored content be the same as the official source. Sort of like294 bit-torrent for websites.296 - map programming :: one problem with functional programming is that297 in order to remain functional, you have to pass up arguments up298 into each calling function to get the full range of behavior299 from the lower level functions. Normally people come to a300 compromise involving abstraction and sparing use of dynamic301 variables to configure runtime behavior. What would be the302 advantages of making a programming language where every function303 receives one argument, a map, which contains all the symbol304 bindings it would ever need? This map is passed on to all305 subordinate functions. This way, you could replace functions on306 the fly, and arrange for there to be sensible defaults,307 etc. Might cause more harm than good but is an interesting idea.309 - rest nest :: a small EEG device you would attach to your head when310 you go to sleep at night. ML algorithms would determine311 your particular sleep cycles. This would mostly be an312 alarm clock that you could give a time range, say313 7:00AM - 7:15AM, and it would wake you up during an314 ideal time corresponding to then end of one of your 90315 min sleep cycles. You would feel much more rested upon316 waking up, and would wake up faster. There might be317 some other uses for the EEG data as well.319 - image compression :: use a library like gimp or opencv to process an320 image to make it have less entropy, then store the reverse of321 those operations along with the compressed simpler image as a322 super-compressed image file (possibly accepting some323 losses). Trades file size for decompression time, and allows one324 to cheat by using information in gimp/opencv to compress the325 image.327 - fixed cryopreservation :: why not use a fixative to buy enough time328 to ramp up cryoprotectants to an acceptable level at room329 temperature? Then, the whole system can be rapidly cooled and330 vitrified. This method "severs the biological link" in that the331 fixatives are highly toxic, but current vitrification procedures332 do this anyway since there can be a lot of freezing damage.334 - dilated security camera :: a security camera that would capture335 full video footage of everything at 60fps but then decide to keep336 only every 1 frame every 5 seconds unless there's something337 "interesting" happening.339 - bitcoin wallet :: Part of "server culture", this would be something340 like "coin.your-domain.com" which would serve as341 your personal trusted access to your own bitcoins342 from anywhere.344 - libpay :: this would be a free library which would enable345 micro-donations to software projects and other projects,346 so that you could donate a penny to "emacs" and it would347 be automatically split up to every person who has ever348 contributed to emacs in proportion to the amount of349 community esteem, code quantity, bugs fixed, whatever the350 community decides. This might make it possible for351 programmers to live entirely off of free programming.353 - distributed graphics :: Browser based graphics-card accelerated354 distributed computing API.356 - pronouns :: use capital letters A-Z instead of pronouns. They solve357 pronoun referents and gender neutrality, are short to358 say, and you can encode useful information into the359 choice of letter. For example, instead of "Meetings360 shall be presided over by the president, unless she is361 absent." USE "Meetings shall be presided over by the362 president, unless P is absent." We already use this a363 little, since I and U are reserved for the subject and364 object respectively.366 - phone DSP :: software app that inserts an audio DSP between the367 input to a phone and the output. The DSP is delicious368 and configurable, and can allow men to make their369 voices deeper, etc. The app would allow you to hear370 your own voice as others hear it. Most people hate how371 their own voice sounds. The app would also allow one to372 immediately change the parameters of the DSP using good373 presets.375 - predestined body learning :: a good example of predestined learning376 might be the mirror neurons.378 - restaurant receipt :: use a carbon copy receipt instead of two stupid379 copies.381 - anti google glass :: glasses with mounted lasers and computer vision382 that targets the cameras in google glass and destroy them.384 - wearable towel :: towel with clasp, velcro, whatever, that allows385 one to wear the towel more securely than just386 wrapping it tightly and hoping for the best.388 - crossdressing :: Easiest way to disguise oneself as a woman is to389 wear a burka.391 - book-mode :: intelligent color highlighting for books and392 articles. It would disambiguate pronouns and involved393 references. For example, if "Rachael" as red, and "the394 blonde haired girl" refers to "Rachael", then "the395 blonde haired girl" would he colored red. Also, you396 could disambiguate multi part run-on sentences by397 highlighting each subcomponent. Maybe would also have398 applications to scientific reading.400 - Handheld light Rain measurement :: this would be a clear, teflon401 coated plastic disk with a camera underneath the disk. You would402 be able to hold the device out and it would measure the rate of403 accumulation of water droplets from fine mists and light rain by404 using computer vision to measure the diameters of the drops.406 - Big Brother Farming :: This would be a vision system that would407 individually monitor each plant and turn on water, etc to ensure408 maximum/uniform growth for each plant.410 - Discrete Faucet :: A faucet with discrete ticks instead of411 continuous.413 - Laser Circle :: take a glass microfiliment and shine a laser at one414 end at an oblique angle. It will make a perfect,415 large circle on the wall, converting a laser beam416 into a laser cone, preserving most of the energy of417 the laser.419 - Invisible Glass :: Take a container of liquid and embed a420 glass sculpture made out of glass that has exactly the same index421 of refraction and color of the liquid. Then the sculpture will be422 totally invisible in the container, and will only be revealed423 when the liquid is drained. The container might be a fancy424 wine/spirit bottle or an hourglass.426 - Caterpillar people :: A race of caterpillar like creatures gains427 intelligence after eons of predation by birds, etc. These428 caterpillar creatures still undergo metamorphosis into a large429 butterfly-like creature. The metamorphosis process turns the430 caterpillar's brain into mush and reforms it into a minimal,431 dumb, truly insect-like mind, completely destroying the person432 the caterpillar was. The society develops all sorts of customs and433 religious interpretations of the metamorphosis. It is viewed as434 good and natural by some since it is part of their life cycle and435 necessary to propagate the species, as only the butterflies can436 mate. Some think that the butterflies are still the same person437 because they have the same soul, even they no longer posses the438 memories or personality of the original caterpillar. Some see the439 butterfly form as the "true form" of the species, since the440 butterflies can fly, mate, and are beautiful. Many make a big441 deal out of the fact that 1-2% of the caterpillar's mind is442 actually preserved in the butterfly. Some see it as a terrible443 tragedy and argue that the caterpillars should try to stop the444 metamorphosis by technology. Practically, some very important445 members of society undergo hormone therapy and/or surgery to446 prevent metamorphosis so that they can live longer as themselves.448 This is a continuation of Marvin Minsky's ideas about pain being449 something that preserves our bodies while destroying our minds,450 something that is a remnant from our too harsh animal days that451 hasn't caught up to the fact that we have very complex brains452 now. It's a worst-case scenario about a maladaptive genetic453 legacy. Also, it's inspired by "There She Is!!!", which makes a454 compelling point about homosexuality by introducing a second455 gender characteristic (bunny/cat, male/female), which makes456 homophobia look very silly. Here, our own biological legacy of457 pain and death is made to look like the tragedy it is through the458 lens of the the caterpillar people.460 - relationships as a business :: [[http://thedailywtf.com/Articles/Up-or-Out-Solving-the-IT-Turnover-Crisis.aspx][Turnover-Crisis]] is an excellent talk461 about the "culture of quitting," which is about better business462 by letting people go instead of keeping them around past their463 "apex". Focuses on information transfer. Cool idea of an alumni464 network, which for relationships would be a group of satisfied465 ex-lovers, who would recommend new people your way, and who might466 consider coming to you again, refreshed from their time away with467 new stories/experiences. I should look for examples of this and468 how they worked out.470 - coffee with tea :: /rlm-tea/ contains 2% sugar, 10% cream, and 20%471 dylan coffee. /dylan coffee/ contains 5% sugar,472 20% cream, and 10% rlm-tea. Start your mornings473 with recursion!475 - psychic crystal :: in a science fiction story, this would be an476 object that is very easy to move physically but is extremely477 difficult to move with telekinesis.479 - http://betsofbitco.in/ :: what a great place for an AI/person to480 prove themselves as a good predictor. I wish this could be481 automated.483 - true reflection :: don't forget about that mirror in the student484 center!, it's two mirrors at right angles, like staring at a485 corner of a room. The light reflects so that it shows you what486 you actually look like, instead of your mirror image.488 - remote control wasp :: use computer to drive wings with remote489 power/logic.491 - encrypted email phone book :: public (distributed?) database of492 email->private-key pairs, to enable automatic encryption.494 - universal eye color :: every equivalent creature will see each495 others' eyes as black -- it's universal. Even if the creatures496 see in radio waves, and their eyes are 2m long pieces of jagged497 metal, when those creatures look at each other, they will see498 black, the absence of light and color (since it's being absorbed499 by the sensor array).501 - intelligent microwave :: it learns where the hot nodes of its fields502 are, and uses them to evenly heat any food item. It has an infrared503 camera or something to keep track of how hot the food is. That way,504 you don't get bowls where the edges are boiling, while the center is505 still frozen. Requires a little bit of intelligence/vision, since506 the exact pattern of heating totally depends on the exact shape of507 the food. Wouldn't need a carousel, and wouldn't need a timer,508 just a desired temperature. Could also detect ice, and automatically509 defrost the parts which are frozen. Might be able to work much510 faster since it can avoid overheating; might have problems with511 heating the insides of thick things, might need a weight sensor too.513 + Would be much cleaner than other microwaves, since food would514 "sputter" and splash liquid much less.516 + Throw in some SIFT+R processing to match previously cooked foods517 and learn the exact heating profiles for things that have been518 cooked before -- it can get faster the more it's used.520 - compression :: brain-aware image compression algorithm522 - Credit card proxy :: would be a company which works like paypal523 except for real world transactions525 - Flesh pillow :: a pillow like the arm or torso of a human, complete526 with simulated temperature, bones, and heartbeat.528 - super screw :: a screw which has only one or two threads and instead529 uses compression to fit into a hole (the whole shank530 of the screw is split into multiple pieces to531 accomplish this; the tip is a point, then the middle532 bulges out and gets compressed when screwed in.534 - light filter :: (like light tweezers) to mechanically separate535 fluids with different index of refraction537 - chalk eraser project :: maybe make a directional eraser, for easy538 release of chalk dust, like fur, and how it likes to rest in a539 certain direction.541 - silver socks :: socks laced with silver for the antimicrobial542 properties.544 - UROP :: magnet gear/metal teeth tape546 - Rod of Moses :: device to distill urine through evaporation and547 easily dispose of urea crystals for use in desert --548 produce drinkable water.550 - UROP :: Make the LED in line with the flow for the micro injector, so551 that it may transmit maximum flow. Motor that changes552 distance of internal magnet from windings depending on553 desired speed so as to obtain maximum power efficiency.555 - lottery scraper :: web scraper which monitors various lotteries,556 looking for "special" gimmick changes in the rules (like 4x557 winnings on Wednesdays) and computes expected value...559 - Memristiors novel design :: make an evolutionary algorithm to make560 old stuff using all four basic circuit elements.562 - Conductive concrete :: concrete that has embedded metal fibers so563 that it can conduct electricity.565 - little bitty melting pot :: might be useful for some types of566 manufacturing/3D printing -- how small can an induction melter be567 made, for example.569 - power strip/timer programmable combination :: meh571 - algorithms :: which learn what their inputs are and in what order,572 and can adapt to changing circumstances -- they573 remember previous arguments and adapt so as to respond574 to different connections.576 - true pure tones :: hear a true pure tone by direct stimulation of the577 nerves of the ear579 - mechanical analogue to the electrical op-amp :: would be an object580 with two levers -- you pull on one lever and the other moves the581 same way, no matter what's in the way or what it is driving. This582 analogy could be useful to teach op amps to people.584 - paper folding device :: make it convenient to fold lots of papers in585 various ways.587 - concrete epoxy :: epoxy with sand/ some other solid material.589 - light capacitor :: suspend some ball of material with a high index590 of refraction and shine light into it so it gets stuck -- would591 the light stay trapped forever? Could you build up unlimited592 quantities of light inside the sphere (which could then be593 released slowly by frustrated internal reflection?595 - movie screening :: Movies always are too long at first. One way to596 shorten them ``scientifically" is to record blink rate during the597 move and then remove / shorten the frames of the parts in which598 there are a lot of blinking (average this over multiple people)599 better yet, put it online and do it across thousands of people. I600 got this from youtube in which there is an episode of kill bill601 which is composed entirely of the parts in which people had their602 eyes closed. slogan: want to make a movie people can't take their603 eyes off of?

Could S remember stuff from729 his childhood?731 - make a completely indestructible phone :: no moving parts or display732 you should be able to slam it around all you want, and it will733 just work. brutally simple. aerogel around the battery, minimal734 interface - never gets too hot, and can be dropped into water. no735 holes -- uses field effects for everything from the buttons to736 inductive charging and data transfer.738 - midi to ocarina "tabs" program :: (online website? buy ocarinas from739 it too)741 - 3d printing with sound pulses (or just patterns) :: like the 8.03742 lecture744 - lighter flint on spring :: make hot, throw it at something, and it745 makes sparkles!747 - nuclear energy :: Rebranding New+Clear Energy with informational748 campaign and public debate forum to enforce its749 transparent and open nature. France needn't be the750 world leader in nuclear energy. (Dylan)752 - bubbles :: Engineer a material which has both ductility and high753 surface tension to make the "third"754 minimal-surface-energy solution to a bubble suspended755 between two equal-diameter rings. (Solutions are756 cylindrical catenary curve, two separated half-bubbles,757 and a double-cone)759 - Textbook whose content can be varied continuously :: alter level of760 difficulty, rigor, diction, emphasize crossover with certain761 other discipline, etc. Content generated dynamically from762 knowledge base, along with questions that are moreover altered to763 guide knowledge acquisition.
