if you see that? >> behind the city, behind the houses, behind those hills. the see any more hills? >> these kids are wonderful. they get to explore, they get to see different things. >> we let them explore a little bit. they get their best. if their parents ever ask, we can learn -- they can say that they learned about the depth of field or the rule of thirds or that the shadows can give a good contrast. some of the things they come up with are fantastic. that is what we're trying to encourage. these kids can bring up the

creativity and also the love for photography. >> a lot of people come into my classes and they don't feel like they really are creative and through the process of working and showing them and giving them some tips and ideas. >> this is kind of the best kept secret. you should come on and take a class. we have orientations on most saturdays. this is a really wonderful location and is the real jewel to the community. >> ready to develop your photography skills? the harvey milk photo center focuses on adult classes. and saturday workshops expose youth and adults to photography classes.

>> the right to vote allows us to vote for candidates or party and it is a significant way to have our voice heard. exactly 100 years ago, women were given the vote in california. the battle for women's suffrage was not an easy one. it took more than 70 years. a woman could run for president in new york.

>> organizing this conference, basically it modeled itself on a declaration of independence for women. it marked the beginning of the women's equality movement in the united states. >> at that time, women were banned from holding property and voting in elections. >> susan b. anthony dedicated her life to reform. >> suffrage in the middle of the 19th century accomplished one goal, it was diametrically opposed to this idea.

>> many feared it would be corrupted by politics. >> women in the 19th century had to convince male voters that having the vote would not change anything. that woman would still be devoted to the home, the family, that they would remain pure and innocent, that having the vote would not corrupt them. >> support gradually grew in state and local campaigns. >> leaders like ellen clark sgt come repeatedly stopping these meetings -- , repeatedly stopping these meetings as a politically active figure. doing everything they could to ground the campaign in

domesticity. >> despite their efforts, the link made it tough whenever voters were in the big city. a specialist in francisco. >> the problem with san francisco is that women's suffrage as an idea was associated. >> susan b. anthony joined the provision party. a deadly idea in san francisco. liquor was the foundation of the economy. and >> anything that touched on the possibility of prohibition was greatly and popular. >> the first campaign was a great effort, but not a success.

>> the war was not over. less than one decade later, a graphic protests brought new life to the movement. >> women's suffrage, the republican convention in oakland, this time it was the private sector response. 300 marched down the streets of the convention center. women were entitled to be here. >> joining together for another campaign. >> women opened a club in san francisco.

it was called the votes for women club. if she could get the shopkeepers to have lunch, she could get them to be heard literature. the lunch room was a tremendous success. >> it was the way that people thought about women willing to fight for a successful campaign. what happened was, the social transformation increase the boundary of what was possible, out word. >> there were parades and rallies, door to door candidacies, reaching every voter in the state. >> the eyes of the nation were on california in 1911, when we all voted.

it was the sixth and largest state in the nation to approve this. one decade later, we have full voting rights in the united states. helping newly enfranchised women, a new political movement was founded. >> starting in the 1920's, it was a movement created by the suffragettes moving forward to getting the right to vote. all of the suffragettes were interested in educating the new voters. >> non-partisan, not endorsing candidates >> -- endorsing candidates, getting the right to vote and one they have their

voice heard. >> the 100th anniversary of women's suffrage is taking place throughout the state. bancroft library is having an exhibit that highlights the women's suffrage movement, chronicling what happened in california, bringing women the right to vote. >> how long does this mean going on? >> the week of the 20th. people do not realize that women were allowed to vote as early as the 1920's. in the library collection we have a manuscript from the end of december, possibly longer. >> in commemoration of 100 years

of voting in california. 100 years ago this year, we won the right to vote. around 1911, this is how it would have addressed. and here we are, dressed the same. [chanting] >> we have the right to vote. >> whether you are marching for a cause or voting in the next election, make your voice heard. thank you for watching.

because we have a great waste water system here in san francisco, we do about 80 million gallons of waste water here in san francisco, which means we basically fill up 120 olympic sized swimming pools each and every day here in the city. we protect public health and safety and environment because we are discharging into the bay and into the ocean. this is essentially the first treatment here at our waste water treatment facility. what we do is slow down the water so that things either settle to the bottom or float to the top. you see we have a nice selection of things floating around there, things from

bubble gum wrappers, toilet paper, whatever you dump down the toilet, whatever gets into our storm drains, that's what gets into our waste water treatment and we have to clean. >> see these chains here, this keeps scum from building up. >> on this end in the liquid end basically we're just trying to produce a good water product that doesn't negatively impact the receiving water so that we have recreation and no bad impact on fish and aquatic life. solids is what's happening. . >> by sludge, what exactly do you mean? is that the actual technical term? . >> it's a technical term and it's used in a lot of different ways, but this is organic sewage sludge.

basically what it is is, oh, maybe things that come out of your garbage disposal, things that are fecal in nature. it's sludge left in the water after the primary treatment, then we blend those two over and send them over to digestion. this building is built to replace tanks here that were so odoriferous they would curl your hair. we built this as an interim process. >> is there a coagulant introduced somewhere in the middle of this? . >> this coagulant brings solids together and lets the water run through. that gives us more time in the digestion process, more time to reduce the amount of solids. these are the biggest ones in the world, like we always like

to do in san francisco. they are 4 meter, there's none like it in the world. >> really? wow. >> three meters, usually. we got the biggest, if not the best. so here we are. look at that baby hum. river of sludge. >> one of the things is we use bacteria that's common in our own guts to create this reduction. it's like an extra digestion. one of the things we have to do to facilitate that is heat that sludge up and keep it at the temperature our body likes, 98.6 degrees. >> so what we have here is the heat exchanger for digester no. 6. these clog up with debris and we're coming in to -- next wet weather season so we always come through here, clean them out, make sure that we get maximum heat exchange during the colder wet weather.

sludge season. >> rubber glove. >> right here. >> rubber glove, excellent. all right, guys. >> thank you. >> good luck. >> this is the full on hazmat. . >> residual liquid. we're taking it time to let it drain. we don't want to get sludge on it necessarily. take your time. stand on the side of it. . >> should we let it release for a while? . >> let it release. >> is that the technical term? . >> this is the most important bolt on the whole thing. this is the locking bolt. it locks this thing right in

place. so now. >> take your hammer and what we want to do, we get rag build up right in here. the hot water recirculates right in here, the sludge recirculates in here. the sludge sometimes has rags in it. all we want to do is go around the clean the rags. let me show you how. take the slide hammer, go all the way through the back, go around. >> got you. >> during the real rainy season, how does that change the way dealing with this job? is it a lot more stuff in there? . >> what we do, charles, we do this quarterly. every four months we go around and clean all the heat exchangers so we don't have a large build up. . >> go around?

. >> yeah. (sound of hammering). >> what i'm trying to do, charles, is always pull it out on the low stroke. >> right. so you are not, like, flying out. now talk about clean up. . >> then where does this stuff get deposited? . >> we're going to dump it in a debris box and it will go back to the plant. >> if you think back, the romans came up with a system of plumbing that allowed us it use water to transport waste away from the hub of civilization,

which enabled cities to grow. . >> you have a large bowl, a drive motor and another motor with a planetary gearbox with differential pressure inside there. the large mass up there spinning separating the solids from the liquid. we have to prevent about once a month, we go in there grease those, change the oil, check the vibration levels. the operators can tell just by the hum of that machine that it's a harmonic noise emitted that it's out of balance and the machine needs to be cleaned. it will start vibrating and we have vibration analysis machines that will come over here and check the levels. so it's kind of an on-going thing that you have to stay on

top of on a daily basis. >> handled properly, you take organic residuals, as we call them, that are leftovers of our society and turn them back into some energy. and we have another ability to take that sludge and get a nutrient value for crops there. we actually are running a kind of composting energy recovery system. >> well, this is a dirty job. we try to do it safely and we try to do it without imposing too much on the public. people want to flush their toilets and have things go away and not be bothersome again. we do a lot to try to accomplish that. i'd like to invite you to come back any time you want. once you got this in your blood, you are not going to be able to stay away. the raging waters are fun and when we do digester cleaning i really hope you can come back.

that's quite a sight. >> yeah, that sounds interesting. >> i really appreciate you coming by and it was a >> the question when i started 11 years ago when i started doing resolution work is can anything be presented on a really low resolution device where it is potentially a digital image? can anything be presented that way? or will it feel cold and electronic? >> the imagery will change. there will be four different sets.

it is a two dimensional image. it is stretched out into three dimensions. the device is part of the experience. you cannot experience the image without the device as being part of what you are seeing. whereas with the tv you end up ignoring it. i make gallery work more self and budget and public art work where i have to drop this of indulgence and think about how people will respond. and one of the things i was interested in the work and also a little fearful of, it is not until you get to the first and second floor were the work is recognizable as an image.

it is an exploration and perception is what it is. what are you seeing when you look at this image? one of the things that happens with really low resolution images like this one is you never get the details, so it is always kind of pulling you in kind of thing. you can keep watching it. i think this work is kind of experience in a more analytical way. in other words, we look at an image and there is an alice going on. -- and there is an analysis going on.

>> i have been a cable car grip for 21 years. i am a third generation. my grand farther and my dad worked over in green division for 27. i guess you could say it's blood. >> come on in. have a seat. hold on. i like it because i am standing up. i am outside without a roof over my head and i see all kinds of people. >> you catch up to people you know from the past. you know. went to school with. people that you work with at other jobs. military or something. kind of weird.

it's a small word, you be. like i said, what do people do when they come to san francisco? they ride a cable car. >> california line starts in the financial district. people are coming down knobbhill. the cable car picks people up. takes them to work. >> there still is no other device to conquer these hills better than a cable car. nobody wanted to live up here because you had to climb up here. with the invention of the cable car, these hills became accessible. he watched horses be dragged to

death. cable cars were invent in san francisco to solve the problem with it's unique, vertically challenged terrain. we are still using cars a century old >> the old cable car is the most unique thing, it's still going. it was a good design by then and is still now. if we don't do something now. it's going to be worse later. >> the cable cars are built the same as they were in the late 1800's. we use a modern machinery. we haven't changed a thing. it's just how we get there. >> it's a time consuming job. we go for the quality rather than the production. we take pride in our work and it shows in the end product.

>> the california line is mostly locals. the commuters in the morning, i see a lot of the same people. we don't have as tourists. we are coming up to street to chinatown. since 1957, we are the only city in the world that runs cable cars. these cars right here are part of national parks system.

in the early 1960's, they became the first roles monument. the way city spread changed with the invention of the cable car. >> people know in san francisco, first thing they think about is, let's go >> we came to seven straight about 10 years ago. -- 7th street about 10 years

ago. the environment is huge. it is stronger than willpower. surrounding yourself with artists, being in a culture where artists are driving, and where a huge amount of them is a healthy environment. >> you are making it safer. push, push. that is better. when i start thinking, i see it actually -- sometimes, i do not see it, but when i do, it is usually from the inside out. it is like watching something being spawned. you go in, and you begin to work, excavate, play with the dancers, and then things began to emerge. you may have a plan that this is what i want to create. here are the ideas i want to

play with, but then, you go into the room, and there maybe some fertile ideas that are becoming manifest that are more interesting than the idea you had initially set out to plan. so there has to be this openness for spontaneity. also, a sense that regardless of the deadline, that you have tons of time so the you can keep your creativity alive and not cut it off and just go into old habits. it is a lot like listening. really listening to watch what is going to emerge. i like this thing where you put your foot on his back. let's keep it. were your mind is is how you build your life. if you put it in steel or in failure, it works. that works. it is a commitment. for most
