9:52 pm
the population, 50,000, maybe the fourth-largest city in the country. he started in the lecture hall's they moved it to a chapel. at the end of the lecture, they said, why can't the citizens do something that john quincy attempted to do before? the first national observatory. before he was president, he was the first minister or today we would say ambassador alexander the czar of russia who had the largest telescope. he taught john quincy astronomy and john quincy had a passion for astronomy the rest of his life. he would record that in his diary. in europe, there were over 30 professional observatories in russia and europe combined. ofamerica, we had nothing
9:53 pm
these types of telescopes. he wanted america to step up in science. he was the promoter of that. the state's rights movement was strong and they did not want to give power to the federal government for what he would call his lighthouses in the sky. they mocked him for calling them those. eventually, they built the naval observatory. depot to be called a instead of the observatory. in the bill that authorized the funding, it's tequila did the astronomers should not do astronomy, only calibrate chronometers for the naval ships. inauguraly at his address in 1825 challenged congress. the observatory was founded in 1842. by the time they got the
9:54 pm
telescope from europe, it was 1845 before it went online in mt. adams in cincinnati. original concept of building the observatory, it would be a private statistic for the members who paid $25 to become members. laborer.too high for a months salary for a laborer. by the time the telescope members of the00 society existed at $25 in member. that was impressive, what private citizens were willing to do to fund this. tory was founded in 1842. mitchell was also responsible for designing and building the observatory. he selected this hill east of downtown. ex-presidentthen
9:55 pm
john quincy adams to town. he was then serving in the house of representatives, 76 years old. eagerly accepted the invitation. he said, i am on my way. he took him two weeks. he used a railroad to go to lake area. -- eire. a stagecoach from columbus to cincinnati. in 1843 for the laying of the cornerstone. all he was delighted, he had two-hour speech prepared permit at the end of the lecture, they said thank you for coming to town. it toaid we will rename mt. adams. one significant thing about that was that was the last half public speech he gave.

-- that was the last public speech he gave. we are in the main observatory. this is where the original telescope that mitchell acquired was put, from the 1870's until 1904. in 1904, they got a newer, bigger, better telescope. at that time, there was not electricity at the site so they would hire a teenager to assist them. have three jobs. the first, coming over and opening the shutters. you pull on a rope and pulley, if process like this. the shutter slides to the open position so you can see the night sky. the second job of the teenager had was to add energy to the telescope to make it work. it was a mechanical system. it works like a grandfather clock.
9:57 pm
the handsergy to make of the clock move. apply that to the telescope. a 400 poundo be block of steel. the teenager would have to crank up the weight. you grab this handle right here and turn the weight. off the ground. gravity is taking over, dropping the weight slowly. but it issee it falling. that is convicted in energy. that is -- that is kinetic energy. you can see the governor spinning at the top, governing the speed of the telescope. gears, therough gears are turning slowly but they are moving. torque is transferred to the long column. then the big 32 inch key
9:58 pm
returns. the main axle of the telescope turns. axisis parallel to earth's of rotation. eventually, the energy turns the the telescope moves at a rapid rate of one revolution per day the opposite direction the earth is rotating. the lens of point the telescope, it will stay on and track that object as long as the 400 weight is falling and providing energy. once it hits the bottom, everything stops. the current mission of the observatory is a nonprofit organization, education. we bring schoolchildren income of 25 thousand visitors last year. we also do public education. we open it up on thursday or friday night for public viewing. we are extending that to more
