A/V Geeks Lunch 3-16-22

so so so so so so so so so so so happy birthday to the av geeks lunchtime streaming show happy birthday to the av geeks lunchtime streaming show [Music] happy birthday dear baby geeks lunchtime streaming show happy birthday baby geeks lunchtime streaming show and many more all right um it turns out i didn't have any birthday candles at the archive except for this one which was presented to me many years ago um yeah so yesterday i was so busy trying to find uh footage of julius caesar being assassinated for the ides of march that i didn't realize that um the first lunchtime streaming show that we did was um march 15 2020 it was a friday it was called the ev geeks quarantine show and the idea was during covid we were going to do a show every friday to celebrate well not to celebrate but to give a distraction to what was happening um in the headlines and turns out over the weekend we came to realize that me going into the archive with my wife who has some health issues wasn't going to work because if i was going to go into the archive then i was going to have to live in the archive this is before uh vaccines and all that so i quickly kind of thought about what i would do and we started doing a streaming show out of the basement of my house uh and i did that initially to kind of give me something to do during the day but it actually proved to be um pretty important for me um because i collect these films and i collect them because i want to show them and you know we did what we we did so that i could show the films because there was no live shows two years ago and so um i feel pretty privileged and lucky to be able to to have been in that situation to where one i had a fast internet connection at the house to i had the ability to show digitized stuff and then eventually schlep over a telecini behind me to the basement and do a show every day gave me a reason to put on pants every day is what i tell people so and i could not have done it without you so thank you so much for tuning in and commenting and sharing and all that so there's lots of anniversaries we seem to celebrate here uh like what number film are we on and what number show are we on but um yeah the fact that we've been doing this pretty steadily on every weekday i think maybe we missed one or two for whatever reason but um we did a pretty good job of covering uh all the the weekdays and uh you know moving forward i'm gonna keep trying to do it uh it might be something where we have more pre-recorded shows um if i'm out of town um i know they're not the best but it's a way for me to keep doing what i'm doing so there you go um in honor of this let's celebrate the state of the nasa center with a short odd video i love that maybe i i should do one for the archive um anyways uh let's watch a film about galileo's laws of falling bodies um all that nasa stuff made me think about physics so here we go enjoy [Music] gravitation draws all objects toward the earth's center as long as the earth has existed objects on the earth have been acted upon by gravity but laws that govern freely falling bodies suspended bodies like this pendulum or other bodies in motion were not discovered until the latter part of the 17th century often called the father of modern science is given credit for helping to develop these laws of motion according to legend the leaning tower of pisa was used by galileo supposedly he dropped objects from the top of the tower and observed how fast they fell regardless of whether galileo made these experiments we do know that he did research in the physical sciences here in this modern physical science laboratory we will recreate some of his experiments for example he dropped objects of different weights and sizes and compared their rates of fall we will make the same kind of comparison by using slow motion photography based on such observations galileo concluded that all objects fall at the same rate of speed or acceleration regardless of size or weight objects that weigh very little such as this feather seem to be exceptions but galileo believed that any differences in acceleration were the result of air resistance today we can prove that galileo was right by using a glass tube from which the air has been removed in the vacuum that results the feather and a coin fall with identical acceleration here is the action repeated in slow motion another problem challenged galileo he wanted to describe the speed of a falling body at any instant freely falling bodies move so fast they are difficult to observe so galileo devised an inclined plane much like this one to reduce or dilute the speed of fall galileo used a water clock to time his experiments here a modern electric timer is used to click off the seconds as the object falls and this device releases the object such as the steel ball and simultaneously starts the timer the distance the ball rolls in each succeeding second varies depending upon the elevation of the plane now we will see the action in slow motion after one second the ball has traveled 10 centimeters in two seconds 40 centimeters in three seconds 90 centimeters in four seconds 160 centimeters and so on here are the experimental results using similar facts galileo noticed that a relationship existed between the distance traveled and the time squared using our experiment as an example at the end of one second the ball has moved 10 centimeters at the end of two seconds it has rolled ten centimeters times four or ten times two seconds squared at the end of three seconds the distance is ten times three seconds squared and at the end of four seconds ten times four seconds squared as a formula s the distance equals ten times the number of seconds squared expressed in terms of acceleration s equals one half the acceleration times the second squared this formula applies to all objects in motion such as the ball moving down the inclined plane for the special case where an object is falling freely instead of rolling the formula s equals one half a t squared becomes s equals one half g t squared where g is the acceleration due to the full force of gravity although the tower of pisa experiments so often associated with galileo may never have actually taken place there is no doubt that galileo deserves an honored place in the history of physical science he was a pioneer in experimental work and he developed formulae to represent some of the basic laws of motion [Music] yeah i love me a period piece they're like well this is a science film so we don't really need to spend a lot on costumes and so yeah we'll just use this beard um pretty great all right uh behind me i said before we have the telecini if i pointed it like that yeah there it is um and from that we can transfer films live and broadcast them to you uh so this is uh making haiku or making haikus i don't know if haikus is plural frying dude somebody somebody get back to me on that all right anyways making haikus enjoy don't use really good ones all the time because i think that'll scare everybody off so sort of you know put mix them up so that there are some good ones that somebody can really tell what a nice haiku can sound like and then so something that are you know not so great that somebody can realize when night is finished the sky erases the moon and puts back the sun early morning light coming through the clouds and trees waking all the birds psycho is like if you if you wish you were to be it you can write a poem about it a tree to somebody is so different just from you know to what a dream means to somebody else so you can look at a tree and feel something about it and write something about it [Applause] [Music] sparkling drops of light through an obstacle of trees happy reflections reflections sometimes you forget it isn't real until the water stirs [Music] collections are gone in the end they come again waving goodbye to me what is a hiker it's a japanese or english poetry with 3 lines and 17 syllables 5 syllables in the first 7 in the next and 5 in the last [Music] trees bushes and deep puny little waterfalls all over the place now that was a haiku the trouble is if you don't know i spell very good and it's a tricky word that you don't know how many syllables are in it like play the anthologist it's easy if you clap your hands or snap your fingers are going plainly and taller just that's six that's a lot i am cold i can't be hot and that's seven it's just short thoughts and you just write down the short thoughts really you can't use as many words as you like to i think you just sort of have to get the whole idea and sort of make it small it's real fun once you get to know it you know at first i thought haiku is gonna be hard oh that's gonna be hard then now it's sort of hard and easy ooh what's that oh [Music] [Laughter] hairy and gruesome a hairy mad monster swamp hairy and scary harry and blue sun weird and terribly ugly frightening weird hairy and goosebumps something you could climb on it's hairy and scary hairy and gruesome and yucky and terrible hairy and gruesome it's like a sense of touch sense of feel sense of taste it's a lot of things of sense i look at something in nature and decide how i feel about it or what kind of feelings it gives me and write it down if i don't like it i can't write about it so i have to pick something out that i like like it sort of comes from looking at something helps or or thinking about something and yeah we were watching leaves and [Applause] maybe just have them sit down and ask them try and write one any i think anything could be a good subject for haiku even like a pebble or something you're gonna write a haiku about leaves write something that you feel write the three lines and try to get as close as to the right number of syllables in each line now let's pretend you want to be water water sees people and fish water rolls and rolls down fast i am the water [Music] i am falling down it's fun to be watered splashing down the rocks beautiful everything itself but have you ever thought what it does and does it sleep or uh where does it go the water looks so clean and powerful that they get dirty how does it get clean how does it feel when you get a fish in you [Applause] rushing joyfully stopping only to recall why it's time to go [Music] babbling water rushing between the rocks where are you going [Music] does the water laugh um it surely cries maybe when it cries it might be the ocean [Music] how does it feel when the sun sets into you or how does it feel when the moon rises [Music] so [Music] [Music] imagination creates new ideas from past experiences from watching hands picking cotton could you imagine a machine which will do the work of hundreds of hands from watching a faltering pen could you imagine a reliable fountain pen containing ink for whole pages of writing men watching soaring birds have imagined themselves in flight looking down on earthbound creatures from the earliest days imagination has helped in the creation of new inventions applied to the problems of lighting imagination produced this and this and eventually modern efficient light from tubes everywhere around you you will find imagination at work imagination in music imagination in art imagination in books when you read books you bring life to them with your imagination you get more out of your reading when you use three types of imagination what you see what you hear and what you feel for example when you study geometry you use visual imagination to help you that cube and cylinder are easier to work with when you can imagine what they look like visualization or forming a mental picture is one form of imagination or say you're studying spanish auditory imagination will help you learn new words imagine the sound hear it first in syllables then put the syllables together into a complete word imagining what things sound like is an important way your imagination can help you here's another way you're thinking about baseball and your imagination is giving you the feeling of the game tenseness readiness for physical action alertness activity you're all set to play ball this is kinesthetic imagination and it's another way imagination can serve you if you use it wisely imagining the feeling of a baseball game will enrich your appreciation of a baseball story and your studies well imagination properly used can help you learn your studies too now how skillful is your imagination let's try out your visualizing close your eyes can you imagine a picture to go with these sounds so how did you do did you imagine something like this now let's try your auditory imagination can you imagine sounds to go with these pictures now compare them with these how did it sound to you here's another what does it feel like to run up a hill like this can you imagine did you feel your body reacting these types of imagination visual auditory and kinesthetic can enrich whatever you do and you can develop your skill in using them let's start to read a short story let's see how to use imagination effectively first concentrate on your purpose the thing you want to imagine it was a wintry afternoon a strong wind blew the loose snow and piled it in ever-changing drifts about the front porch of a small plain house this is your goal what you want to imagine winter snow wind the front porch of a plane hops you begin by calling to mind things you remember seeing that might fit the description you recall a plain house you have often seen but this house has no porch and it's not winter you've often seen another house in winter with a front porch and you remember another house which you saw on a snowy day the houses you remember none of them fits the description exactly but you can create a house with your imagination using the parts that fit your purpose you use the first house you remember because it is small and plain but you'll have to imagine it with a front porch now imagine what it looks like in winter and finally what it looks like on a windy afternoon by using visual imagination you can create a picture of the scene in your mind now what does the scene sound like you remember the sound of winter wind and you recreate that sound in your imagination now there is one thing left to imagine how does this scene feel can you feel the wind can you feel the cold try letting your body respond easily and freely this will help build the imagined feeling now have you imagined the scene you need to appreciate the story keep the words in mind it was a wintry afternoon a strong wind flew the loose snow and piled it in ever-changing drifts about the front porch of a small plain house wait a minute the emphasis is on the front porch you have to imagine yourself a little closer to the porch that checks better with the original description let's review the steps used in creating such a scene in your imagination first concentrate on your purpose or on the new image you want to create think carefully about what you propose to imagine then recall relevant images that's the second step remember things you have seen things you have heard and things you have felt in the past that are similar to what you want to imagine then create a new image adding as much enriching detail as possible do this by picking out the parts of relevant images that fit the purpose and discarding the rest and finally check with your purpose test your new image against what you set out to imagine in the first place and make adjustments in it if necessary until you're satisfied that it fits your purpose these are the steps to effective imagination these are the steps to follow when you read when you write in your speaking in your problem solving in your listening develop your imaginative skills in all your activities now can you try the procedure on the next part of the story a group of children bound homeward from school ran across the yard to the porch making snowballs laughing shouting as they ran how about that can you imagine it here is your start can you see the children in the scene can you hear them can you get the feeling of the scene how skillful is your imagination all right so this is the problem i have this little um mute button on my microphone and if i accidentally click it twice then it just unmutes and then mutes again so that's what happened so anyways what i was saying was the making haiku film narrated almost entirely by kids and that's kind of how they did things in the 60s and 70s as educational films started using kids talking to kids because they knew that kids would listen to other kids they responded better to their peers um and i was going to what i said was let's look at this cornet film that was made much earlier and see who's talking in this and it's almost entirely voice of god narration and you know someone you don't see or know who they are and they're telling you stuff and um probably didn't translate as well probably was not as well received uh by kids um so anyways that's what i was saying um as we know two years into this uh besides showing awesome obscure 16 millimeter films we also have a bevy of technical problems that excuse me never go away there's a complexity here and part of it is when you tell me in the comments to unmute i don't look at the comments until i'm finished talking so if i if i'm muted i'm going to be blah blah blah blah blah blah and maybe i'll look and i'll see that oh i'm not seeing a waveform sometimes i won't so i hope you appreciate that um this is what we do live this is not a um rehearsed uh thing this is me doing this off the cuff and i know that that rubs some people the wrong way you know some people are like why don't you do this or why don't you do that i'm like because i'm doing it live baby and i've scheduled out this time to do it and this is what we're doing and we're gonna sit and watch some films uh sometimes it's gonna run great sometimes it's not and that's just kind of the way it is so sorry but not sorry because if i did have to rehearse it then that would take up more of my time and that doesn't i can't pay the bills that way uh anyways what do we got i got another film set up on the telecity um and so we're gonna try this again i think this film is from the 70s i'm not sure it's called sycamore street enjoy and the papas were coming home after work it was over on sycamore street just a couple of blocks from here it all started on the fifth floor where the hagopians live mrs hagopian is a great cook you know [Music] [Applause] [Music] without her glasses mrs kia can hardly see [Music] down the hall there was trouble in the abramowitz apartment that cute baby esther had been crying all day then mrs abramovitz found out why [Music] then there was trouble in 5c where the beans live telephone trouble [Music] then things started to happen on the sixth floor too little bronwyn burns found the key to her father's car you'll never believe what she did with it [Music] things even went wrong for the animals that day look what happened downstairs in 4b when benji popper went to feed rusty [Music] next door to benji the kinds cat thought her pan was great with its fresh newspaper lining [Music] [Music] that mr kinds well when he found out that his evening newspaper was lining the cat's box before he had read it he roared like a tiger [Music] you know jimmy o'brien he stayed up almost all night [Music] yes that sure was a time for things to happen on sycamore street [Music] i think i'll walk over there and see just how things turned out there you go sycamore street um you know so this is a language arts film so kids are now supposed to write about their neighborhood or something that happened in film or you know that's that's what this is all about it's designed to provoke discussion uh this next film i think is a coordinated film maybe it's eb not sure world trade for better living um this is kind of interesting because we when we think about things nowadays in uh in terms of slot supply chains and the availability of products um this is a film that says like oh the fact that we're buying and selling things in the world improves our way of life and we have certainly seen that with different things like the scarcity of microchips or various types of products um or things getting stuck somewhere um either because they haven't been manufactured yet or they're all kind of in a log jam or because a giant um ship is stuck somewhere which supposedly happened again uh but this time in north america it was the same company though it's crazy anyways uh yeah let's look at uh this convincing film about how great world trade is enjoy [Music] this is my ship i've skipped a good many years sailed her over a lot of ocean she's a good ship but you'll find her like in any port from baltimore to singapore and back what's our cargo well it's anything that goes into trade anything that anyone wants to buy or sell anywhere in the world and you know people almost everywhere trade with other countries they have to to get what they want yes we deliver the goods they need to people in every part of the earth and most folks couldn't live as they do without world trade how do i know well i visited a lot of places in my time i've asked questions and this is what they say trade with the world well captain here in britain we depend on it you know after all when we shop for a bit of meat or anything else in the way of food products we're likely to find it comes from denmark or australia or south america what's more the stuff we work with in our factories often comes from other countries too yes putting it as simply as i can i'd say we in europe have to trade or die you say it's food they need captain here in south america we have more than enough of that plenty of good beef cattle and grains and other crops but we too must trade for we need manufactured goods and most of these we must get from you we may not trade to live but we must trade to live better [Music] live better truly captain that is our great need here in the lands of asia we are poor by your standards most of us are peasants yet we grow scarcely enough to feed of many people as for our other needs most of us still use the simple things we make ourselves if you are to live better we must have many of the products of your western world we need goods from your machines and we also need the machines to make more goods for ourselves for all this we must trade [Music] well captain here in the united states we seldom think about the need for trade except perhaps when we're looking at british woolens or when we're trying out a new perfume from france of course we know about coffee and sugar and products like these but what would living be like without all the other things we import there's the box side we put into aluminum wire there's the natural rubber and other raw materials and the manufactured products from abroad that we depend on for everyday living for instance how many people driving cars know that some 200 materials from other countries go into the making of them believe me we need trade as much as anyone yes trade's an important thing most of the world's people ties us together closer than we realize for instance he just mentioned sugar well we just brought in the cargo of sugar from down the caribbean you know much of the world's sugar supply comes from the west indies and many is the time i've seen the people that work on the great plantations cutting the cane and hauling it into the mills this is where the traders take it over they ship most of it to europe and north america we bring it north to the ports now over there they brought in another very necessary cargo a shipment of tin all the way from the mines of malaya here's where we get more than half the world's supply if he went for these men of malaya who dig the oar and wash and work it into pure tin we'd be hard put to it for the familiar stuff that we use to cover all those tin cans but now come along i'll show you something else about trade this country exports a great many essential items too right here for instance they're taking on a cargo of wheat and you know we in north america and the argentine furnish a good part of the world's wheat supply we grow most of it out on the western plains wheat by the millions of bushels yes here's grain enough to take care of the needs of goodly numbers of the world's people now here they're taking on a cargo of cotton this is one of the biggest articles in trade and a good part of the world supply is produced here in the united states not long ago it took a lot of people working by hand to pick the cotton in these fields but today one man can do the job with a picking machine after they've taken the crop to the local gin where it's cleaned of seeds a good deal of it is shipped along to the ports bound for manchester and other textile centers where they make it into cloth you know it takes a great many people doing a great many things to keep the world's trade moving if we could eavesdrop on all the trading going on everywhere in the world today it would probably sound like this singapore november 26th [Music] [Music] the trade of the world is a vast affair but its principles are just the same as trade in your own hometown in every community in the world you have a division of labor with different people producing different kinds of goods and exchanging them with one another for if everyone tried to produce everything he needed no one would have enough of anything now the same principle applies to the world community with people of different countries also producing and exchanging different kinds of goods certain areas contain vital raw materials such as the tin ore the oil the copper ore the cotton the wool the natural rubber the manganese and other products the world needs there are also certain areas most suitable for particular crops such as the bananas and the coffee the sugar cane and the cocoa the tea and the meats the dairy products and the grains and other necessary foodstuffs this makes for specialization in the world's production most of the world produces various raw materials and foodstuffs but little manufactured goods these areas produce most of the world's manufactured goods the people of these industrial areas have to obtain many of their foodstuffs and raw materials from the countries that produce them likewise they supply manufactured goods to the people of the rest of the world but the greatest volume of world trade is between the industrial nations themselves these nations producing the most demand the highest standard of living and thus have the greatest demand for goods for in the world as in our own community the more goods we produce and exchange the more goods we have to consume the higher our standard of living can be right that's why i can't understand why so many people seem to be against trade i think of it every time i see the customs inspectors checking causal here or at any other port all these regulations on imports and exports these tariff schedules these quarter systems and embargoes all these restrictions on certain types of cargo just to keep goods out of the country it doesn't make sense to me well captain the nations of the world working together in such international conferences as this have recently done much to lift the barriers to trade many nations have agreed to lower tariffs and reduce controls while programs such as the marshall plan have helped many nations to restore and increase production laying the basis for a healthier world economy but international cooperation depends upon public opinion and when citizens anywhere meet to talk about trade the discussion often goes like this henry we're concerned with these editorials you've been running these pieces on trace gentlemen i wonder whether you've really read these editorials of mine i suppose it's natural for people to want protection against competition but when it comes to our foreign trade you want to remember that we sell to other nations as well as to buy from them when people like you put on the pressure for more protection asking for higher tariffs and other restrictions on foreign goods then people in other countries do the same they just don't buy our goods why not if they need our goods they'll buy them not if they can help it for one thing they face the problem of the balance of payments with us balancing their payments what's that the balance of payments now here maybe this will give you a rough idea of it my point is simply this in the long run other nations pay for their goods with the goods and services they sell us they can't do this profitably if we raise high tariffs against their goods or if we use quota systems to limit the amount of goods we buy or if we refuse to trade with other nations except the ones that will barter with us barter how's that barter wealth when a government barters it makes deals directly with other governments to swap certain specific amounts of goods now just about every nation in the world today is seriously hampering trade through one or another of these methods what's the answer henry just open our doors to everybody's goods no but the problem is to encourage a growing volume of trade under conditions reasonably good for the people of all nations and just how can we do that well look here one necessary condition is to do away with barter and encourage a many-sided trade moving relatively freely among all nations let's consider a single situation barter is two-way trade now suppose a nation like denmark is buying machinery from the united states on a strictly two-way basis she may get dollars to buy this machinery by selling goods directly to the united states however this two-way trade enables her to buy only this much machinery but suppose on the other hand the united states pays dollars to a country like malaya in exchange for such products as tin melea in turn pay some of these dollars to britain in exchange for her manufactured goods and britain pays some of these dollars to denmark in exchange for dairy products this way denmark would have the money to buy much more from the united states than she could trading directly and this has been a many-sided transaction giving more goods and services to every one of the nations concerned yes i can see that but what about the competition between labor with low living standards and labor with high living standards you get into trouble there well in the short run we might have to consider that but in the long run we must remember that people who produce any article efficiently have no trouble from competition now this is true of highly productive workers in mass production industries of course but it's also true of the people who are producing types of goods that cannot be as easily produced anywhere else in the world and it's true of workers who are producing articles requiring special skills that have not been developed in other countries in other words let's raise our productivity everywhere and let the people of every nation give us the things they can produce best that's sensible yes gentlemen that is sensible for wherever people produce efficiently they are adding to the world's wealth and whether they are weaving nylon in america or weaving rugs in india they are producing goods useful to us all the world is rich in its vast variety of resources and strong in its reservoir of human labor able and willing to transform them into goods all we need are the tools and the machines to produce and the skills to give the world a better product from the australian rancher growing the wool to the danish farmer producing a bacon from the worker packing beef in argentina to the craftsman making machine parts in sweden everyone in the world has his special contribution to make to the world's wealth its supply of goods and services and when through trade with one another we exchange the goods and services we produce we are making better use of the world's wealth making more goods and services available to all satisfying more of the wants of people in industrial nations and fulfilling more of the needs of people in less developed countries giving us all a higher standard of living yes more production and better exchange provides more goods and services to more people everywhere in the world and we'll see that they get it that's what i mean about trade the more of it there is the better it is for you and me and everyone else we're all in the same boat and she sails steadiest when she's hurled down and full steam ahead so uh it's uh it's kind of crazy um that film um you know trying to explain the concepts to uh young people about world trade and how great it is but you have all these old like white men talking about oh it's so great increasing productivity productivity and it's and then you have that graphic of money going from one country to another and it's all the icons are like men and you know it's not that far off the idea that you had people who would go to these countries and then they would kind of uh work with whatever was happening locally and then they were the middlemen that would then trade with the americans um but it would leave i mean the only brown people in that film and people of color were the laborers um and so i don't know i could show this this film in a class now in college and that would be people would be probably furious but you know that's i show these films they have a historical precedence but they do sometimes get it way too right more than they know um so anyways uh speaking of imports uh coffee we like coffee uh it keeps us going um it caffeinates our brains when we have a minor sinus thing going on uh you can buy us coffee at ko fi.com slash av geeks uh you can also go to avgeeks.com and buy dvds and you can hit the like button the subscribe button a thumbs up all that stuff um again thank you so much for joining us today we have more films tomorrow a lot more films um new films showing up all the time like i just a bots showed up with like five new films the other day and so um new stuff is showing up all the time and i'm happy that you're there for me to show them to you so everybody have a great rest of your day and we will see you soon take care you
