Notes

0:04November night in 1509 Galileo first
0:10pointed his new fine life at the moon
0:13setting behind the build of fabula and
0:15began to sketch what he observed from my
0:19observations have the next to the
0:22opinion that the surface of the moon is
0:24not smooth uniform the great number of
0:28kilometers believe it and the other
0:30heavenly bodies be uneven rush of cavity
0:37from in lot of microstates of the earth
0:41leave a change of lunches and the moon
0:47Galileo saw was earth-like and he fetch
0:50it features with earth-like detail
0:54la either serve the move through a
0:56series of phases and he apparently made
1:01some adaptations to his instrument and
1:06organics exploring the pilot now Jupiter
1:10was the one that was in the most
1:13favorable position for observation it
1:15was closest to the earth that particular
1:17point and when Galileo Jupiter he saw
1:22three very bright little stars visible
1:26with the naked eye on alignment Jupiter
1:29and you can mark on that he had no idea
1:31what day wherever he thought that the
1:34favor basically Kickstarter's the things
1:37that we will start the 10 since
1:40potential remarkable configuration he
1:43came back to it the next night and
1:46though yes there were still 3 stars but
1:50their relative position to jupiter has
1:52changed and within a week he realized
1:56that what we have here our moon of
2:02Jupiter like the moon goes on the
2:03earth-moon go around Jupiter and there
2:07are four
2:10in a little more than a week Galileo had
2:12found the first new astronomical bodies
2:14to be discovered impatient I'm this
2:18discovery class with the common belief
2:20that the heavens revolves around the
2:22earth alone gotta lay low with the zubur
2:25Russian friends if the date of discovery
2:30from the first observation of Jupiter's
2:32satellites until you realize they
2:34removed a genuine 72 Cherusci he was in
2:41print by market 12 to put without the
2:45various limbs hear the story messenger
2:48was an enthusiastic announcement of
2:50telescopic from the first printing sold
2:54out within days and use spread across
2:56Europe of Galileo and his amazing
2:58telescope
3:02Galileo became an advocate for his new
3:04astronomy and refined to hip-hop
3:12it was the spring of 1509 in Venice when
3:16Galileo learn about a new device headed
3:19by that's my glass which faraway objects
3:22you that they were nearby
3:27practical compared to telescopes are
3:31very low-tech but they have been around
3:33for several hundred years it was only
3:35when lenses became available in certain
3:39range of strength that want to take the
3:42risk infection and combine it with the
3:45stronger from a village and get an
3:47appreciable magnifying effect
3:50LMAO work out the mathematics of the
3:53telescope and will certainly make it
3:55more useful hearing your quote the new
3:58invention lens maker and determined to
4:02find myself was able to Galileo realize
4:09that technical makers could not give him
4:12the lenses that he needed in order to
4:14make this device more powerful just
4:16weren't good enough and they weren't and
4:19device itself in order to improve the
4:22instrument she had to teach himself and
4:27that is extremely difficult and it
4:30certainly wasn't initially general a was
4:34most interested in improving the optics
4:36of the telescope and by planning his own
4:38lens he was able to increase the power
4:40of the telefilm temples but soon
4:44Galileo began using his telescope slow
4:46to heaven
4:47serving the rough surface of the Moon
4:49Bay the venus and jupiter and some pot
4:53each new improvement in the technology
4:56of the telescope for greater and greater
4:58understanding of the universe
