(gunshots) >> narrator: oswald asked to be a radar controller. he received training and then shipped out for what would be his first great foreign adventure: a posting at atsugi, japan. >> what he arrived at, at atsugi air base in japan, wasn't simply an air force defense base. it was a cia base, and the cia program taking place at that base involved one of america's most secret and important reconnaissance missions: the spy plane which became famous as the u-2 plane. >> narrator: did oswald develop ties to the cia at atsugi? there is no hard evidence. what is known is that he started to learn russian and openly espoused the virtues of marxism to fellow marines. >> if you complained about, "oh, we've got to go on a march this morning" or "we've got to do this this morning," scrub barracks or whatever we had to do, if you were complaining about it, he would say that that was the capitalist form of government making us do these things. karl marx and his form of government would alleviate that. >> narrator: even though he was nicknamed "osvaldovich,

>> narrator: there's a reason she's being so careful.she's writing a letter from shakespeare to his mother. she doesn't want to leave a trace of who's actually writing it, but as she reads from the letter, she has no idea she's being taped. smith then goes with moore to drop the letter in shakespeare's mother's mailbox. detectives retrieve it before she sees it. >> the phone call, the letter -- she's just digging a hole. we thought that that point would push her to do something even to a bigger scale. >> narrator: the next day, the polk county sheriff's office names dee dee moore a person of interest in the case. they make one thing clear -- investigators don't believe her stories. >> typical dee dee moore -- whenever you get her into a corner, you can almost see the hamster rolling in her head. "i've got to change my story. i've got to come up with something believable." >> narrator: days later, greg smith has his secret recorder rolling as moore tells a new story. she admits abraham might not be missing of his own will. he may be dead.

narrator: without half of its water supply, the city would shut down. for nearly 40 years, new york has been in the process of constructing a solution. man: this project is water tunnel number 3. we started on this project in 1969. i'm a sandhog. i've been a sandhog for 37 years. narrator: sandhogs are the men of local 147, who work deep below the city. they began building the infrastructure of new york in 1872. from the subways to the sewers, the water tunnels to the highway tunnels, new york city thrives because of their work. ryan: you got one little hole in the ground, and nobody knows we're here. see the empire state building, right. that's 1,000 feet. so you figure, you go down 1,000. how high that is -- that's how far we go down. narrator: stretching more than 60 miles under the city, tunnel 3 is taking generations of workers to complete. ryan: i don't even want to imagine what my father had to go through. when we first started, it was a rough job. everything was dynamite. now, they have these machines called "moles." it's like a big drill, and i

narrator: the world needs energy. and nearly 80% of it comes from burning fossil fuels -- oil, natural gas, and coal. but burning these fuels emits carbon dioxide, a greenhouse gas that contributes to climate change. how can we continue to supply our ever-growing need for power without damaging the environment? one possibility is to put the carbon dioxide back where it came from -- in underground rock formations. the midwest regional carbon sequestration partnership is investigating this strategy, which will help mitigate the effects of the continued use of fossil fuels for energy. renewable energy sources are another option. and in golden, colorado, the natural renewable energy laboratory is trying to scale up processes for creating biofuels from the products of american farms their goal is to supply up to a third of the country's gasoline needs within 25 years. both projects are pushing the limits of modern science in hopes of leading the way to a more sustainable energy future. 40% of the world's electricity comes

narrator: 97% of the earth's water is contained in the oceans. some forms of life flourish in this salty environment. but humans require an abundant supply of freshwater. less than 1% of all the earth's water is readily available for human consumption. in the semi-arid desert plains of the southwest united states, where rainfall averages just 2 1/2 centimeters per month, tom maddock studies this scarce resource. dr. maddock: the real problem that we have is that with increasing populations and shortages of water, we are becoming very vulnerable. in the southwest, there's a very unique vulnerability here, simply because where do we get the water if there is no water? narrator: across the country in northern florida, the quantity of water isn't an issue. rainfall averages an abundant 1 1/4 meters each year. wendy graham and her colleagues evaluate and model the impacts of industrial and agricultural land use threatening the world's largest collection of freshwater springs. dr. graham: right now, the biggest question is how far we can stress the sys

narrator: large amounts of rainwater can cause flooding. engineers developed two approaches to stormwater infrastructure to transport water away from the urban environment. one approach was to carry waste and stormwater through the same pipe. this combined system was less expensive than building two individual pipe networks. and stormwater was seen as a way to flush out the sewers. through the 19th century, the combined system was considered state-of-the-art throughout the world, and is still in use in many cities today. but cities constructed these systems before treatment was the standard. and even today's largest treatment plant doesn't have the capacity to treat the sudden volumes of water rushing through a combined system during rain. the plant is overloaded, and the excess rainwater, mixed with untreated raw sewage, is diverted straight into local waterways, creating a combined sewer overflow, or cso. there are over 700 communities in the united states with combined sewer systems. the other approach was to separate wastewater from sto

narrator: so jackson looks to the past. and while he researches all of the human impacts on the ocean, like pollution and global warming, his focus has been on the effects of overfishing. he has concluded from various sources that the global population of large fish has declined by 90% since 1950. dr. jackson: we know things like that from data from the japanese fishing industry. they have a massive fishing fleet, and they kept very good records. and in the beginning of the japanese fishery, they fished mostly close to home. and then they depleted the fisheries in the western pacific. so they moved into the north atlantic and the south atlantic and the central pacific and the indian ocean and all of the different fisheries grounds around the world. and in a period of 25 to 30 years, in the entire global ocean, the catch was depleted from 10 fish per 100 hooks to one fish per 100 hooks. that's 90% of all the big fish are gone. narrator: but to jackson, this study also falls victim to the shifting-baseline syndrome. dr. jacks

narrator: atlanta is a rapidly growing urban area. its primary source of drinking water is the chattahoochee river, which also provides water to many downstream communities. but its infrastructure is dangerously old, without outdated facilities and combined sewer overflows polluting the watershed. the city faces strict consent decrees and lawsuits, along with a severe lack of funding. man: when i started working for the city of atlanta in the late '70s, we were approaching that point in time where a lot was going to be needed, in terms of rehabilitation and upkeep. most of the very large pipes were at least 80 years old. we had needs that were identified in the '50s and in the '60s and in the '70s that were deferred. woman: we are urging that we all try to find a way to overcome the obstacles and limitations that might exist. woman: when i was running for office, i met someone who knew mayor hartsfield, who, in the late 1960s, said, "i don't know who the next mayor will be, "but i know they'll have to fix the water and sewer infrastru

narrator: over 300 million people live in the united states. each person uses an average of 100 gallons of water every day. man: what it takes to actually make clean water is somewhat a mystery to most customers. woman: so how does water get from the river into your house, or here at school? woman: somebody has to bring that water to us, and somebody has to take it away when we're finished with it. man: the water infrastructure is vital for disease protection, fire protection, basic sanitation, economic development, and for our quality of life. man: you just can't visualize all the assets that are under our feet. we have about two million miles of pipe in this nation. if you're walking around in an urban area, you're probably stepping on a pipe. man: our grandparents paid for, and put in for the first time, these large distribution systems. woman: and in many cases, it's not been touched since. man: we're at a critical turning point. much of that infrastructure is wearing out. narrator: our water infrastructure is made up of complex, undergroun

(narrator) all musical traditions have established forms. these forms can be looked at as models or formulas which are used by composers and performers to structure their music over time. however, the way this is accomplished can vary significantly from one culture to another. [ensemble playing classical music] i think everyone views form differently. like there are many ways you could organize music just as, you know, if you or i were to organize our daily schedule, we'd all have our own way of doing it. it so happens that in western classical music, it's organized around the idea of things repeating and things developing. and the sort of constant conflict between repeating something that you know or changing it. (pagano) in western classical music, there are many different kinds of forms and some of them are shared by other mical cultures. but there's one form that is very unique to western classical music and is very much favored. that's called the sonata form. now, the sonata form is not just used for what we call sonatas. it's also usua

(narrator) improvisation is a central ingredient in many musical traditions.s is certainly the case with jazz. while the underlying form of jazz is based on composed works, in essence, to be a jazz musician means to be an improvisor. (redman) we improvise in every aspect of our lives. i'm improvising now when i'm talking to you because i don't know what i'm going to say before i say it. improvisation is something which is basic to human life. [jazz music] in jazz, what you're required to do is to play what you feel at the spur of the moment. but you are also required to improvise within certain contexts. you have to be aware of the written melody that you play. you have to be aware of the harmonic sequence. in most cases, you're going to be improvising within and around that harmonic sequence. you have to be aware of the length of the song, of the form of the song because in most cases, in jazz, you're going to be improvising around that form. usually, the prewritten part of the performance is very short relative to the whole performance. you begin by stating

narrator: an impressive letter to a young painter and from the distinguished sir joshua reynolds. could he be right? ( harpsichord continues ) john singleton copley loved his country, but he wanted the richer artistic influences of the old world. besides, talk of revolution was everywhere. political contests, he felt, were neither pleasing to an artist nor advantageous to art itself. in 1774, copley left; it would make him a better painter, he thought. sad for him, sad for america: he never returned to his home. at 34, john singleton copley was already one of the best and most popular painters in the american colonies. the young american artist john trumbull said of him, "an elegant-looking man dressed in fine maroon cloth with gold buttons, this dazzling to my unpracticed eye, but his painting, the first i'd ever seen deserving the name, riveted--absorbed my attention and renewed my desires to enter upon such a pursuit." copley had more work than he could do. early in his career, he mastered the popular rococo style: rich texture of laces and lush fabrics, empty faces. but like m

[ narrator ] at first, the door to the united states was open to anyone... who could survive the dangers of travel to this young, distant land. that hope to be in america was so great and so sunny, that it colored all the pain that we had during our trip. the first night in america... i spent with hundreds of other recently arrived immigrants in an immense hall... with tiers of narrow iron and canvas bunks.

narrator: with the help of the funding the city raised, atlanta has been implementing an asset management plan that evaluates and addresses their infrastructure issues. hunter: it's a continuum. at one end, you have your regular maintenance that you do every day on the system, and at the other end, long-term planning so that every year we're repairing, replacing the right things, and we don't have to do it all at once, which is, quite frankly, what we're having to do in atlanta now. griffin: we have thousands of assets that we have to keep track of. we have to always know their condition and continuously plan for their refurbishment at the right time. one of the things we're required to do under the consent decree is inspect our system. we're trying to find where there's leaks. so we blow smoke into the sewer pipe. man: we're locating places where water from the surface to the ground is running into the sewer pipe and overloading the system. hunter: we have 1,600 miles of sewer. we are evaluating every linear foot of that system. is the pipe leaking; are you having a lot of infiltration o
