[inaudible conversations] [inaudible conversations] spread good evening welcome to the strand it was funded by my grandfather in the area known as book road that ran along Fourth Avenue and it housed 48 bookstores from the 80 needys through the 60s and then since then the the strand was passed down now to me to be kept in the family. Very excited to wellcome a power couple dr. Kelly and zach her work is been published in the scientific journal anzac known for his morning comment comic called cereal. Which is a web cartoonist choice award so this dynamic duo says then use their podcast so with this money and creative collection with the up and coming fields of study to take cubans directly to the moon and also theyre working on a oneyearold baby. Also thrilled to have cspan booktv so for the format tonight we will talk then open the microphone to your questions and then they will sign copies of their book please join me to welcome kelly and zach to the strand. [applause] hello. We are thatth weinersmith we wrote a book. [applause] it is called soonish i am kelley by steady parasites and the other one with of breakfast cereal restarted to write the book in 2011 in a bunch of undergrads are talking t heads blowing hot air . With the is rangingity from mostly white but also mostly want wrong but they all had jobs and we should write a book because queeney have job security. And then to predict future technology it isnt particularly interesting how long weinersmithat thinks there will be a space elevator but what happens exists . So to tell you about technology for the major problems we need to overcome and how that can make everything more awesome or horrible. So we will talk today about one of the technologies are the chapters so as we do research we discovered a lot of stuff that is weird we cannot keep it to ourselves so you have to buy the book for this is one of the Amazing Things that we uncovered. So with all sorts of ways to get to space more cheaply than the conventional rocketit method so we scored different technologies and some totally plausible. But for this talk we will tell you about a few of them. They q. Thats a rocket. And just starting to have been so the idea of the reusable rocket to make it more like a plane travel so imagine every time you went to fly from new york to los angeles you would jump out bin the plane exploded that would be cool but expensive. So a big part of why it caused 60 million is the way the rockets were cry now. And to get the most expensive part of the machine then a couple hundred thousand. So spacex could kind of do this they landed part of a rocket but the way space travel works is in three rocket stacked on top of each other in the reason is one to use up the trunk you dont want to carry the deadweight so you drop it into the oceanou but spacex could take the biggest and landed on a barge. This is a good for step in the direction and elon musk said get the price down 90 multiplied t by his conversion factor. [laughter] then you end up with 30 or 40 percent which is the enormous. That is happening right now by the innovative Concept Group including putting a rocket a giant springlike a pogo stick to get things going. Also the space elevator that is three parts. The station in the ocean that stays in place, a giganticpl table then the counterweight is a big rock with an elevator that clients that is slowly goes up the cable. The people who were interested in this design estimate they could get stuff up into space at 250 per pound which is amazing because right now is 10,000 per lb. Said today 50 a pound is amazing savings. So to figure out is the middle part. [laughter] it is kind of important. In the is to be very strong but it cannot wait a lot because 62,000 miles long and the weights ofto the accord will yank it down. So someone it r recently the discovery of a car bin manner tubes carbon nanotubes like us the size of a hair. Together we know all the information we are 18. People manage to get them to be a foot and a half long. Remember 62,000 miles the have a long way to go but it might be Strong Enough to do a better problem so for those terrestrial based purposes with the carbon nanotubes you only need a foot and a half to do just about anything you want to do wonder if. So if you draw out those projections longer and longer and faster and faster than it flattens out. If they are long enough to get that moving again with those really alone carbon nanotubes were doing questions at the end. Hold on to that. So if you can get it long enough it turns out theyre not very good purpose of your askingsk nasa about lightning apparently there is an area that has never experienced a lightning bolt so the answer is to put it there and hope that the past tells us about the future. [laughter] i hope climate never changes. [laughter] that would be embarrassing. Sola and other problem when he getting considered too much but even in that paradigm if you drop from high up with a Nuclear Missile with the Nuclear Warhead mechanism is ticklish for girl but then if you drop a dense metal there isnt a good way to deflect that. So then at which point you are in a worse position. But the deep part is is that permanent quality of life there isnt a good solution to thehe problem i dont know how much faith you have been human politics even having faith there are other governments so the other reason you want that base station in the ocean you want it to be cosmopolitan strictly for political reasons the first nation that has that space elevator like you can conduct anywhere on anyone else. Higher ground literally. I dunno if anybody does but there are some serious will enforce laws. I thought you were going to tell everybody. Yes. When you cut the cable. Guest to guess . The elevator flies off. The down part will fall but if you cut a sling with the rocket you snipped that no matter where it goes up in a Straight Line essentially that happens with a space elevator. Except for the people in the elevator. Gh rinaldi held in a piece of space junk any part of of the cord goes through the satellite people are dying the way to lose millions and millions ofll dollars. But it is interesting what happens if you cut it high with those whiplashes . Actually it isot fortuitous but its actually a little boy that i disappointed that nothing bad happened. So some of the concerns the idea that you could destroy everyone but the reusable rocket with a ton of propellant that is something we need to decide if we are all okay with. And you can trust people with that. In terms of how we could change the world . End in those particular places in the few words of meanspirited economist because four and a half percent of the discretionary budget. Ee not the return on investment. It then to change how we feel about the martian colony is. If it is cheap to get stuff up there that for example, 10,000 to get 1 pound of stuff if the space elevator worked you put the stuff in the elevator you build the spaceship bin space now suddenly you could be that type of species to get it up their chief putsches mind going and amazing for me to imagine. So now talk about robots taking our humanity for but that was dense. Here are one of the favorites these are stories about the robots in humans. Ended is designed to assist humans especially the elderly. It keeps trying to escape and set leastwise that has got away for sure now. And a the robot escaped and it is tragic. The job thisay caretaking that is the first robot story. So as an undergrad at Harvard University how much they would trust the relation to enter the door and. So give me those three reasons why it . [laughter] sow number one i of the huge issue interested to get the photos of inside the door and switches creepy that it is nothing. She have had people still cameras in the windows to take pictures inside her door and. Book dorm and there was a bomb threat recently they were told not to let anybody into the building there are lots of reasons not to let people in but not to let the robots and. Associate robot to control by sitting at a table to say let me in the building and 21 percent said yes. Maybe higher than you would like but if you got to the group 71 percent said yes if any robots are out there taking notes. But the real trick to get the robot so it came up with a box from the pizza order but it did not contain fancy cookies there is from the local grocery store. And then you were likely to be let into the building. Palins would sell each other out for cookies from the garage restore not even the good ones. Then in the final story at the Georgia Institute of technology how humans would trust robots in the emergency. So there are these undergrads were told to take a survey following the robot into a room then they really smoke into the printer on the fire alarm. They could follow the robot to safety or leave the way they came l in. They know how to get out of the building. We clear. Almost all of them decided to follow the robot. [laughter] that seemed crazy but realize that is a slowmoving robot. [laughter] is practically crawl their way out and they knew how to get out. And then to circle the room but then the undergrads still follows but then the last thing that they did they had the robot when the smoke alarm went off go into the room the lights were turned off and blocked by a couch and the robot stood there. We undergrad had to be retrieved because he stood there waiting for the robot to do something else. Theyre not stupid their Georgia Institute of technology they are the best and brightest but we really trust robots. But in each case they were no better the with a trash can with a red ribbon. They dont even have to look like a human to trust them with our life but if you have a cookie u. S. Can do what everyone to the american undergrad and they will go with it. [laughter] that is one more from our book. Thanks for your time. [laughter] and we will be happy to answer any questions about book Sort Technology and raise your hand for a microphone. Mentioning carbon nanotubes is that the filament you leave it to gather it is just one . There is a quantity if you are inclined if you would like superman hair light and strong and it just hits the spot and that strength already is not ideal for engineering but the moment you start to leave them you increase the likelihood of a specific breakpoint and any break point is bad. So youre literally talking about a 100,000meter long molecule. So imagine that honeycomb shape of carbon if youre just one vacancy how harry the problem is. It sounds impossible but there are a lot of technologies that meet crazy levels but we all have markets nobody needs 10 feet of that molecule for that composite material or 100,000 kilometers. How many did you start with their how do you narrow that down . Restarted with a 60 than it was clear he couldnt do more than 20 but then as nerds weve got 25. And at the time we finish writing a couple chapters ted would be the number because of how wordy we are. We found technologies that are not so new but with those crackpots or so for a long the only thing left word details so we we did those note retried to be dealt economics so actually the last chapter is a graveyard recent onemo month researching realize that it would not work. Like computing was too complicated to do in a way that was Accurate Enough spec with quantum computing. I cannot explain that. [laughter] there are certain constraints the longest chapter is 10,000 words so i think we rode about twothirds of that then no joke it was one sentence after another trying to get it across. We thought do it properly or not do it. That isnt the only stuffed but with that argument we wanted to talk about had to fit a certain length. Also Something Interesting for a month and not be too repetitive. Can you give some examples . She has veto power. [laughter] the of lubricated single use monocle. [laughter] [applause] i still dont get it. I dont know how that happens. So it is interesting actually because i looked grumpy but im not a grumpy person in the there are our children. [laughter] how far out to ru scrambling the night before every date for every comic urge you have a month stored up . Right this second i have exactly enough typically and not scrambling to try to get a little bit ahead with kids. I tried to be two weeks ahead but that is unusual. Which of these technologies . That would be the worst situation. We also talk about castrate mining that is an important part to make that happen figuring out how to label times its so then they move them to some other place but then the thought to fleeing an asteroid that earth is terrifying considering the track record. But just to give you into ration intuition the example of our moon to earth takes more energy than from the moons to earth they dont even have enough to hold themselves into a sphere. So to get enough traction you can fly upon them in a motorcycle which is so cool. [laughter] but, with the brain computer interface and that would be unrecognizable also via that the last vestiges of privacy in the ability to interface to give up that last thought is a little more ominous like a boost your iq or memory with economic advantage that it is rather severe you could get to the situation this happen a a if far as the academics wouldd inhibit the drug so in the d market if you have a nice interface system everybody uses the device. That is a little freaky. Is everybody understand the brain interface . As a followup what about those economic forces . With those fundamental process. So to take a human being but that great computer computer face person so when you reiterate that so even with those technologies with having no stendhals and friends on f facebook so the legend that they will get to where all the plots are shared with one another . So the answer that i expected was so delayed san figures will move but then we will load all of our thoughts into a cloud then be one big super organism as as something everyone talks about . But one day we can all probably brains into one cloud and a field that is horrible both marriages in a society work because that is not happening. [laughter] and to whom i spoke with that want to divorce my wife. And to make a good point what is the need for humanity . So if we ever get to that point that is way beyond to be totally different kinds of cubans at that point. So talking about humans is that true bohol trusting we are of robots . T like tested technology . Did not have good science on this but if you look at Science Fiction there is the general trust and we have been dispensed with that that it seems naive but so the joke that we tell like looking at terminator it is flattering to humans with the time machine and then the fancy exoskeleton in in the the skin looks real person is the trash can with cookies laugh [laughter] is all the you need. We are more trusting in the moment. So my guess would be but they were more or less trusting because they hate each other . And not often get the definitive answer but it is an interesting question. Which emerging technology were the most poorly communicated. And with quantum computing impart a foil we decided not to do that they universally felt i dont know if you read about quantum computing that that would be faster somehow but it is highly suspected but not yet proven to my understanding it is almost certainly the case that we dont know for sure that the map will shakeke out so that solves so all of those problems with a super computer is a beautiful machine. Tuesday quantum computing can break that algorithm that is much common . That is probably true of from one vendor states and theres no way toe switch so with that crypto military advantage is highly questionable. So getting into the exs email is cool but. [laughter] and the there is a wonderful book is a pretty thick book so that plaintiffs listed bad. So to have a space elevatorr that travels up the so there is the contest how to get power of the space elevator to keep going with the carbon nanotubes to root kerry itself up. There is some evidence and not have that specific strength. And what i would like to say is the development on space elevator. Everything else is engineering. So any news item that you hear is questionable. Im curious how much of this was reporting with people or painstaking care articles or renewals or books . It was both in we read a painful number of books. And for every chapter i interviewed three or four people in the field and additionally and if you are interested in the whole process that would be recorded live on the episode and then went through to make sure we had records because wete forgot we had to write the bibliography. Paper co give us one week. [laughter] 95 of the source material is primary with the academic article with the book of proceedings to be an expert in the field. So if you are interested in the field to help with that is the goal. So with a parasite has to kill to complete the life cycle bin it infects a wasp that lives in the treenc branch. The lost it makes a compartment toli undergo development it doesnt get infected it chooses whole in flies away the withtttt infected it makes the oil lost shoe a holden plugs the whole with intent since there as it eats the inside it is the crypt keeper the edginess was already determined man named after the egyptian god who trapped his brother in a crypt in scattered the body parts of the open at the crypt you can find this scattered remains of the wasps that it kills the crypt keeper wasp. I appreciate that. The driver gets frustrating when a brandnew Development Keynote how do you deal with that . The answer would have been drinking. [laughter] this sow with spacex being fined and finishing the chapter on augmented reality a then put the mondo cane now. [laughter] everybody has a different idea of augmented reality reality, and then we talk about hypothetically if you have this world augmented to be in ways with the real way they did not want that to interact. Somebody drawing a swastika on the dollar tumbling negative door can you ask them to get rid of that bin pokemon go had stops in the Holocaust Museum rand we were able to say they can do nothing this so the answer is please stop being a jerk. Pokemon go should not be at auschwitz. Get him out of there. They complied. The experts and augmented reality said pokemon go doesnt count. The way you play pokemon go with augmented reality it covers youror vision giving you the perception virtual objects are interfaced with reality. You see a little dry again hopping hopping up and down but with pokemon go he is just floating generally geographically somewhere but in the ideal setting he would be sitting here with of shadow make a specific new ways know that there is ang book here to hop over that. That is called being in registration with reality and pokemon go isnt just quitee that. So with that academic distinc
