dot men and and them and and we're at the beginning of a new wave of research creative powers of the inspections in we're leading surprising things about how we sent to the world around us exploring the mysteries of the spoken word uh... lawyers lawyers lawyers lawyers pictures to us resistors wear well with one another so i think in the first go around here we come back let's just has a right to sign these men are design engineers at bell telephone laboratories the research and development part of the bell system they're about to engage the new breed of computer called graphic one in a dialogue that will test the ingenuity of both man and machine it's a new way of working out abstract problems in the age-old medium of drawings and designs which explains why the technique is called computer graphics our researchers have an idea for a telephone filter circuit they want to try out but they need a ready answer for the problem if they do this what will happen they could spend many hours in the workshop building and testing the real thing they'll draw their second directly on graphic ones cathode ray tube the operator talks to the computer with an electronic liked him which does a precise an easy job of assembling the symbolic parts of the decide diodes resistors transformers and all automatically position by the pan connecting them as it goes along probably much more readable three-term realized on the lower right hand the stones if they change their plan that's no problem out there there's no need to memorize complex rules for the computer signals the action when it's ready if the researchers have done a good job of programming what they want the designed to do the computers quick to point out any breakdown in their logic hip-hop level of mumble this dissipation package make that one i don't also striking the design is complete but will it work at this stage a remotely located master computer takes over the job of calculating the performance currents of the circuit harris pat also lost was also have to worry about the amplified based on thurs and so is letting say we're not doing it right that's a good how much trouble is that they get that change to some of the color just buying the right place in the program make the appropriate change order on the whole thing again let's make a party a call of or to say columnar one square and right once worked to see what will get that is the program going through these lina consulting graphic artists and the bell laboratories scientists are collaborating on an idea for an experimental computer made movie you know and and brightness idea of you being able to two programs and so we know what it's supposed to do and what i get a great deal of the sponsor of this it don't know what it's exactly going to do it exists images and it is interesting to me that you say the unexpected thinks that enough because in in a sense the computer is has done exactly what you told us to do right there's shooting script is and it's a good set of instructions written in one of several programming languages available operations this one dis deflects short for bell labs flex this is an excerpt from the basics computer movie showing other scripts the articles in the country cards will only be used only in this fit into the computer winding up was a real of recorded time learning i've got another story near andrea arsenault i don't know greathouse suffers walkie-talkie hispanic just explaining clean air five point six seventy david perfectly focus and under computer control on the trade information is prohibited in rapidly moving made up of a finals edwards varying line intensity the synchronized movie camera more demanding with photographs the best moving images as their plotted and wrong on the face of the cathode ray tube the brutal purple from people broke rabin on remind bravo are all these they have hadn't usually mean happened for her don't have higher being resistant then manual and balloons promotion republican phylogeny charter this technology only cooperate this technology into into my aunt and and have the two weeks ago frist was felt lines there's an idea is that i'll be able to sit someplace in a railroad station and uh... write a movie or maybe even think of a telephone of entry and write a movie besides creating unique visual effects and you know movie is going to use to show phenomena we can do renderings eating this bill in the scraps the motion of the communication satellite by starting in the scientists can obtain new insight into the satellite stabilizing system boldly a man orbiting alongside good observant in the same way and room experiment is in visual perception using computers to create weird random patterns that never occurred in real life to find out what and how people see when these patterns are shown to the these veterans curiously reminiscent of a point a little of the nineteenth century i just sort of was beautifully integrated paintings are formed by compass computer like docs and actions the other server is an incredibly methodical technique that produced only a dozen or so paintings in his lifetime today researchers are generating that many in a single day to vishay contains your proceeds objects of studies that look deep into the future of communications when we learn to separate the relevant from irrelevant in visual information will be on the way to sending three-dimensional color picture messages over ordinary telephone lines mother with him and then we found that when you get back are now not only do the small pictures disappear because her not close enough to see them individually and the big picture comes across but as you get even further back than the picture takes on a continuous tone part is not where photograph rather than being a very crude computer generated spatially quantized right one of the interesting things to me was that you can drop quite a distinguishable picture unjustly eleven by eleven array of black spots unlike spots the entire musical score accompanying this film was composed of a computer can produce nearly endless their issues aside better ways tonight's speech speech is still very common music is simple salivate using it describe you thinking and also be used for speech deal by spending nixon really the the easily your and programming as well as like composing for conventional musical instruments accepted note replaced by numbers the computer converts these numbers into impulses that cause sound waves to come directly from a lot of an cruel regarding marrying money who right what actually happens when we hear sounds we know that the membrane of the interior changes sound waves into audible sensations but until recently no one had seen the whole inner ear connection then sound waves strike the membrane it makes thousands of microscopic movements per second qualify computer recalculate your and for that first-time borrowing his product it takes several minutes of this motion to draw the simple ceremony since the model of the interest being expressed that the medicare it can be pictured in different ways in this three-d_ version the membrane is given a spiral shape requiring has it receives shocks from simulated somewheres outside and saw a their problems and showing three-dimensional movies insure these movies are from boston there are some people feel quite interesting exciting waukesha yes i suppose it as an educational for character allows people to see things which are only mathematicians achieved before practice people who've seen most interesting work medical doctors people are going on darman's renewed seemingly so simple is a very complicated process no one believed understands brutally mundial all mean madyun manuel unit more energy and reminded about andrew have memorial day-to-day remember our agreement on martin barbara j are again coffee are novel made by tomorrow here manhattan mcbride work for you those words were spoken by a digital computer program to stimulate the speaking machine much of what we know about force in speeches stored in the computer's memory from there we can experiment with more advanced ideas in areas that are still unknown takes stress how do we always seem to know just which parts of spoken words to emphasize let's start this inside that sentence basketball more scientists can only begin to explain how we speak please stress lives without thinking giving them find shadings of pitchmen intensity are a lot of charlie mostly black at the in chains that stress on outside when fanatics symbols of fed to the surface as is it combines them into intelligible speech are in our age articles you back are a large articles gradually but let's see if it had a quietly look at the picture high-paying jobs right away media inflection and his strong are a large lawyer tells you that that's the fact that improve back are a large articles collapsed the art of computer graphics fees on the inner city yet it is already stimulating the rate of only have about areas and where is it just like me to get complex an unwieldy it offers not only the means to quicken the pace of discovery but an ideal way of communicating want we may discover room and no one
