Many students gone here and there. You are going to have to do a lot on your own to get caught back up. Hopefully, this website will help.

: Modern Version of Cavendish Experiment

: Cavendish Experiment

: Poor Tycho.

: Red marker shows Tycho’s island

: Tycho built the castle and observatory Uraniborg on Hven in 1576 (with a laboratory for his alchemical experiments in its cellar) and then Stjerneborg nearby in 1581. Unusual for the time, Tycho established Uraniborg as a research centre, where almost 100 students and artisans worked from 1576 to 1597.[

: The separate Observatory on the island of Hven.

: Tycho’s Observatory today.

: Tycho’s view of our solar system.

: SO what is the slope of this line?

: Even my AP Physics girls started to wear down in late April. HANG IN THERE! It will be VERY worth it to you.

: Mar’s apparent Retrograde motion if you are using the Ptolemic system. This required early 16th century Ptolemic astronomers to add epicycles (circles within circles) to planet’s orbits.

: THe true reason (using Kepler’s system) why Mar’s appears to have retrograde motion.

: Kepler’s shapes

: Kepler’s explanation.

: Kepler’s geometric shapes within shapes which laid out the distances from each planet to the sun.

: The Harmony of the Sphere’s. Kepler’s attempt at making sense of the solar system and homage to God’s beautiful design.

: Kepler’s museum in Prague. Not nearly impressive as it should be considering he changed mankind’s view of the solar system.

: Carl gives his respects.

: Kepler meme.

: The Kepler telescope is launched in 2009.

: The Kepler observatory is “specifically designed to survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets”.[7] A photometer continually monitors the brightness of over 145,000 main sequence stars in a fixed field of view.[8] This data is transmitted to Earth, then analyzed to detect periodic dimming caused by extrasolar planets that cross in front of their host star. It’s already found almost 3000 candidates.
