  137. 1:45 >"i decided i try to print an entire fashion collection from my home. The problem was that i barely knew anything about 3D printing". facepalm Something that's confused me for a while is why we even refer to these artists as "professionals". If i decide to make something, that i have absolutely no idea howto do, then i'm described as a "layman". But this artist does the same thing, she has the exact same lack of necessary skillsets, and she's called a "designer". I mean, an architect knows their material and howto make buildings from them. A mechanical engineer knows their material and howto make machines outof them. If you have been trained in a profession where you know nothing about your chosen medium (lol how do i 3d print things?!), then of what use was your training? How would your results be of a higher quality than that of any other layman hired off the street? Maybe that came out as more negative than i intended. I'm just confused why we elevate these people to a class label like "Artist", put them on stages, listen intently to what they have to say, when they clearly deserve no more respect nor attention than any other layman. Why is it a thing? Don't get me wrong - what she's doing is indeed quite cool & interesting, but it's no more interesting than what any other maker is doing *, why has she been elevated to a higher status class? *infact less so, because other makers tend to know their mediums and thus more often are really pushing the boundaries of what's possible. All this artist is doing is buying off-the-shelf 3d printers & flexible filaments and repeating what others have already done, why does she bother? But more importantly - if this is so banal and derivative, why do we bother listening? Shouldn't our time be better spent listening to those who know their medium and are truly pushing the limits? TL;DR: TED your entire stage is broken.

  281. vanarcken113 Sadly what i said is indeed true.  Algae farming (& biofuels in general) and solar power are competing interests of mine, a few years back i was closely following a fair few algae projects (as my old videos attest to), and i still occasionally tinker with algae-tech ideas to this day. Algae is the fastest growing plant on the planet, it's the best, but photosynthesis isn't particularly efficient compared to man-made tech.  It's great for producing liquid fuels though (ie: for vehicles), very simple.  That's why there's so much buzz about algae, exciting stuff.  But everything has it's limitations.  It's more than just great for fuel, but also for food, and even carbon sequestration.  This stuff has a lot of uses, but it doesn't do everything. If you search for Algae Thermodynamics there's a fair few articles which will catch you up. But as a quick explanation: Think of how much land is required to produce X amount of biofuel for combustion cars (wikipedia has some good biofuel yeild numbers, algae is the best).  Then compare to the same land-area covered in solar panels charging electric cars.  It's almost no comparison, the electric cars come out way in front, mostly because the thermodynamic limitations of photosynthesis just can't be routed around :(.  You can easily charge your own electric car from the solar panels on your roof, but to grow enough biofuel to fuel your own car takes a relatively gigantic amount of land (i'd have to dig through my old notes to give you the exact land-size required), the yields are super low.

  297. +Troy Milton one way is that they can first have an number of ideas of how it might work, and then they devise relevant experiments to test the ideas individually. For instance, they can introduce a specially shaped molecule* which they imagine should block or interact with one of the processes. If it has absolutely no effect on the cell in an experiment, then it would heavily imply that their ideas on how that process works were wrong. They can keep doing this until they find things which do have effects, then they analyse all of these things to build up a picture of what could (or definitely couldn't) be happening inside the cell. Over many experiments and testing of ideas, the picture becomes clearer. It's sortof like being in the dark, trying to figure out what an object is by repeatedly poking it with a stick from different angles, and keeping notes of when you hit something and when you don't. It can take a while, but over time this data paints an increasingly clear picture of the shape of what you're poking. It's like a game of connect the dots, each experiment gives you more dots, and marks some other places as "definitely no dots here". Every time they do an experiment and get more dots, and more "no dots here" areas (i think i'll call these "anti-dots"), they then can have another round of brainstorming to try to figure out what the picture could be. They take the best ideas from this brainstorming, and then devise new experiments to test the ideas, ie: "if this idea is correct, then there MUST be dots right around here and here." Even if the experiment fails to reveal dots there, it will instead reveal a "no dots here" area, and this data will still add to their picture. So even if an experiment fails to prove a hypothesis, it's still a win win situation. I guess the boardgame of "Battleship" is another which can be used as a metaphor. Each single shot you take gives you very little data, but over time it builds an increasingly clearer picture of things you couldn't previously see. It only takes a very little experiment, repeated slightly differently time & time again, to build up great amounts of knowledge. *Thesedays we have such a huge amount of knowledge about chemistry, that we use computer simulations to model what we know. This makes it easy to find new things we can experiment with, because it's sortof like "the computer simulation shows that the shape of this molecule should effect this thing", and then we test it in the real world to see if it's true. Remember all the poking with a stick we've previously done, by now we have a really good idea of the shape of various things, we even have a whole bag of specially shaped poking sticks to speed up the process. Thesedays we're super confident about the shape of most things, we only really poke specific areas we're not sure about.

  481. +Cayden Normanton I can understand your reaction, but we live in a world where there are a lot of people trying to pull a fast one on you. Science is a huge target for this, there's countless people trying to pass their work off as legit unbiased science when it's not, trying to pretend they are an authority they're really not. This is one of those "if it sounds too good to be true" situations where it's best to assume the worst. There's enough scientific work being done that DOESN'T have red flags like this, so it's best to prioritize the work that has no red-flags, and ignore everything questionable. I agree it's a sad state of affairs where some scientific work can get ignored just because it's not PERFECT, but we're spoiled for choice and shortstaffed. When bad science makes it's way into the media (and it very often does), it's often stuff which was riddled with red-flags from the get-go. So if you put the bar so high that no questionable red-flag science gets through, you cut out a disproportionate amount of bad science in the media as well. re: your Water-Tap example: If none of the taps in my house ever had a problem in 40 years, i would be amazed. It would be strange, even though my taps are of high quality - i still would have honestly expected at least some normal problems like a leaky seal here or there, i wouldn't expect a 100% success rate over 40 years. Sometimes a farm crop gets wiped out by a flood, or locust plague, or some sortof blight. There are countless outside forces which can effect crop trials, which is why they have to do a lot of them to average out the results. If results are PERFECT 100% success rate it's very very suspicious. Over 40 years, with so many farms, you would have to have some failures.

  547. Brandan09997 i scoff when i look at a shiny 3D rendering of a futuristic phone, with a caption reading "This amazing phone's charge could last for 100 years and be powered by unicorn farts, kitten giggles, & quantum woowoo", yes. Any designer can render & write whatever fictional story they want to go with the artwork for their fictional devices, but actually constructing a device that will function under the known laws of physics is another story. Sadly, designers often aren't trained too well in this. It's easy to design a (effective & competitive) hand-held laser pistol, low power prototypes already exist, hell you can watch real videos here on youtube of people's DIY pulsing laser blasters, it's known tech. What's hard though is powering it (to a sufficient level) with known battery tech, that's typically the limitation in the real world: the density of energy storage. Another one is the economics of actually constructing the device (It's common to see designs for all sorts of things that stipulate ridiculously expensive materials, or construction techniques which are still barely being understood in universities - let alone in use in industry right now). Most of these things are "what if". But sadly the media reports on them as if they're just around the corner. This serves both the design firms and the media well, they're generally more interested in page views and SEO exposure ratings than any sort of accuracy in reporting. To answer OP's question directly: TBH the reason we don't all have exoskeletal power armour is because we're civilians and have little need for armour. But the reason we don't have exoskeletal suits is because they're a relatively new tech. Exoskeletal suits already exist right now in a primitive (still mostly prototype, unaffordable) form, but it's good enough to predict that they'll be cheap and commonplace tech perhaps within 10 years, we'll get there with slow incremental improvements alone. No exotic materials needed, OP is in luck, we just need time. I'm glad OP didn't ask for (useful) personal jetpacks tho, that's a much harder nut to crack. Sorry, no flying Ironman suits for a while yet.

  603. Destro7000 These "feminists" you're describing, who aren't striving towards equality, are what we call "Strawman Feminists", because they mostly only exist in people's heads and not in reality. You're not railing against feminism, you're railing against something else, something that doesn't even exist. A fake target. Well i shouldn't say they don't exist at all, the world is pretty diverse and i've met some crazy people. But they are very rare, and certainly not what mainstream feminism is about. The thing is though, that most people who are anti-feminism like to argue against feminism by painting it as exactly what you described, they paint a weird picture of what feminism isn't - claim that this is actually what feminism is - and then use it to justify their stance against feminism. But really they are attacking something else, they're attacking a fake "Strawman". I mean, if you're for egalitarianism and gender equality - then you may find that your viewpoints could be quite inline with feminism, and you're merely calling yourself something else. But on the other hand, if you get annoyed when people talk about gender issues, and think it's all dumb "feminist talk" instead of just normal human talk about important and highly relevant issues in our lives, then yeah you're probably not a feminist. To me, it sounds like someone in 1700s America saying something like "Wow all this anti-slavery talk is so annoying, i wish people would just shut up about it." The fact that you don't think this is important weirds me out, but TBH it's a feeling that most feminists are pretty used to :(

  622. nitwndr The battery continues to (try to) supply power (somewhere between 2.5V and 4.2V) to the phone at the same time as the charger is supplying 4.2V to both the battery and the phone, the 2 sources are connected in parallel, so the phone only ever sees 4.2V like usual. It's all connected to the same single terminal: the positive of the phone, positive of the battery, and positive of the charger. A fully charged battery will supply 4.2V to the phone, an almost discharged battery will supply maybe 2.5-3V. When the battery is being charged - the charger supplies 4.2V positive to the battery's positive terminal (ie: it's in parallel). So as far as the phone is concerned it just sees 4.2V positive on it's positive terminal, just like usual, all that's changed is that there's slightly more amperage at it's disposal (comming straight from the charger). Inside the battery though is where things are different, it's suddenly seeing voltage at it's positive terminal (from the charger) which is comparitively MORE POSITIVE than it's own positive 2.5V. You have to remember that voltage is a relative thing. This means that to the battery - if it's charging it's own positive terminal to 2.5V positive, but there's an outside positive voltage of 4.2V, then what it's actually experiencing inside itself on it's positive terminal is 1.7V of NEGATIVE charge. The battery's own residual 2.5V positive is cancelling out 2.5V positive of the incomming 4.2V, (it experiences that 4.2V positive as relative to the 2.5V positive that the terminal already had) thus leaving a RELATIVE voltage difference of 1.7V in the other direction (ie: negative). So yeah, while charging there is indeed a reversal of voltage going on, but it's only the inside of the battery itself that is experiencing it. :) It's like having a bucket that is pouring it's water out onto the ground slowly, and you're occasionally topping up that bucket with a glass of water. The water pouring out from the bucket never stops, and the level in the bucket is normally going down. But when the glass is topping up the bucket - the water level in the bucket suddenly starts going up (this is like the internal reversal of voltage the battery is experiencing, the weird experience of it's water level going BACKWARDS is only experienced by the bucket itself and no-one else), even though the water pouring outof the bucket isn't effected and just keeping going during the whole process. My point is that when you are recharging that bucket, it doesn't effect the pouring out of the bucket's water onto the ground, it certainly doesn't make the pouring go in reverse. The only reversals that are happening are within the water-currents of the bucket itself. I hope that helps :)

  623. The rest of the talk was ok, but the first 1/3rd of the talk (ie: before snowden was brought up) was so outof touch with people's concerns. Covering the whole planet with Google's balloons?  It was so stupid to talk about that.  We are all incredibly concerned with privacy and governments ability to co-opt any tool they wish to, just like they co-opted Google, Facebook, Apple, Microsoft, Yahoo, etc and use it for whatever evil purpose they want to. I mean, it's like dropping crates of guns into a despotic area - thinking it will help the civilians protect themselves from the government.  Is it really any surprise when the local government will receive all of those guns and use them to further subjugate the populace. You need to design protections into the systems themselves. Google's data should have all been anonymized and encrypted to protect everyone from NSA spying, from the beginning, it should never have been possible for anyone to steal your (more like OUR) data without your consent. If you drop balloons all over the world, what do you think's going to happen?  The NSA is going to come along and say "here's a secret court order, all of this is ours now, thanks a bunch for building a geostationary global spy network for us".  Your corporate policies on user data protection are so piss-poor you may as well just think of yourself as a contractor building infrastructure literally FOR the spy agencies, since they have the legal (and/or brute-force technological) power to just take it and all of the data you've stored. To talk of creating this balloon network, with no mention at all of safeguards.  Wow.

  870. You can imagine how it'd be useful for a filter-feeder to sieve water until it had concentrated a lot of nutrients into a storage location. It's water still - but now more concentrated with nutrients. Sortof like how a humpback whale filters water krill through it's mouth until it has a mouth full of highly concentrated krill water (then it finally swallows). A filter feeder (like coral polyps) might do this too, concentrating it's collected nutrients into a protected area. It could also use this area to store all kinds of things, like important chemicals that it doesn't have room to store in the polyp but are too important to permanently disard, coz they'll likely want them again later and it's handy to not have to waste all that time & energy to filter for them in the ocean all over again. I can see how this could easily evolve into a circulatory system. Also, it's sortof a way for filter feeders to evolve an anus. Normally they only have 1 hole, but with a circulatory system the polyps can specialise and become a multicellular system - all sharing the same circulatory system, all dependant on it and all evolving to defend the collective "environment" that is now the collective body of a multicellular organism. So some polyps can specialise on filtering from the ocean (mouth cells), and others can specialise in maintaining the health of the blood (liver, kidney, pancreatic cells etc). As the body gets bigger, they'll need cells that can move the circulatory system around more. They'll also need a way to remove waste from the circulatory system. You can't just flush the whole thing out, you'll lose all your collected nutrients, so you must filter the waste out and dump it. Congratulations it's an anus. :D

  1116. re: The Q&A at the end. Just want to correct something: Evolution does not at all suggest that life out there in the universe would be using DNA with 4 or 6 letters. This is not a new thing. When TED owner Chris walks onstage to ask this question after the talk, he seems to think this is some kinda change to how we understand life & evolution. IT'S NOT. This is not a change. Infact, science already had a robust understanding of evolution long before we had even discovered Chromosomes or DNA (let alone that it has 4 letters). All that evolution suggests on the matter is that if there's other naturally occuring life out there in the universe, it must have evolved, and to be able to evolve it must have some form of data storage . It likely won't be DNA like ours, it might not even be stored inside cells, it just has to be some way to store/edit/copy information . That's it. And the very end Floyd suggests that we may find life out there that doesn't even have DNA (by which i think he means it won't have a way of storing data at all). That's pretty dubious, if we ever found something like that then we probably wouldn't categorize it as "life". There are many things on earth that already fit that bill, many chemical reactions (eg: sped-up footage of metals rusting) do look & act very much like they're alive in some way, but they aren't. The main reason we know they're not alive is because there is no data storage at play, there is thus no way for it to evolve. At it's base level, "life" is really just a specific sub-category of chemistry, it's chemistry that has a way of storing/editing/copying data . All chemistry isn't life. If chemistry doesn't do this - it's not life. That's not to say it's automatically unimportant & not worthy of protection & respect. It might be it's own new category of chemistry. (ps: "DNA" is just shorthand for the chemical name Deoxyribonucleic Acid, the chemical our biology uses to store our genetic information. But since alien biology would likely store it's genetic information using other chemicals, we wouldn't call it "DNA", it'll have a different name)
