Having forgotten about Herschel, I had distilled the issue down to Cassini and Kepler. Cassini not seeming Germanish I go with:

Kepler

1) Is he dead? Yes.
2) European is correct.
3) A she he ain't.
4) His work was confirmational to that of another.
5) He is a pre-1900s figure.
6) He is not pre-Galilean.
7) There is a space mission with his name.
8) Mission orbit should be no more than 1.5% more than Earth's.
9) Not William Herschel.
10) Johannes Kepler is correct, Jedi.


...and what did he help confirm?

man, I was going to say Kepler from the beginning except that he didn't use telescopes.

this was taken of me and a friend at Kepler's birthplace.

should we say "Kepler's Laws"


supposing that is right, I don't really want to take this from Arneb since he did most of the asking.

Are you sure about that? Did they let you in the museum?

Very nice! I just finished reading Kepler's Witch. Wow, what a tough life he had! The book was an easy read and more captivating that I thought it would be, but considering all the obstacles he faced, there was a lot to hold my attention. I do regret that there was not a lot of information in the book that addressed his scientific findings and efforts.

Thanks for sharing it. I would like to go there someday.

The answer is not any of Kepler's laws.

Nice, though none seem to show the one important project he performed that I am quizing about.

Better hurry with your guess, Texan, since Arneb and Eroica are waking up 'bout now.

we've got another 10 hours or so. It is just 7:30PM for Eroica and an hour later for Arneb.

Quote:
a treatise on optics as applied to telescope lenses (1611)

Quote:
After hearing of Galileo's telescopic discoveries, Kepler also started a theoretical and experimental investigation of telescopic optics using a telescope borrowed from Duke Ernest of Cologne.[38] The resulting manuscript was completed in September of 1610 and published as Dioptrice in 1611. In it, Kepler set out the theoretical basis of double-convex converging lenses and double-concave diverging lenses — and how they are combined to produce a Galilean telescope — as well as the concepts of real vs. virtual images, upright vs. inverted images, and the effects of focal length on magnification and reduction. He also described an improved telescope — now known as the astronomical or Keplerian telescope — in which two convex lenses can produce higher magnification than Galileo's combination of convex and concave lenses.

Kepler was the first to explain how a telescope works. [Galileo had promised he would, but never did, apparently. The fact that Galileo procrastinated doesn't surprise me considering that he was making new discoveries with it, and he was an enterprising individual, justifiably so.]

But, no, that's not the answer. Kepler had requested from Galileo a telescope, but Galileo never would send him one. As you stated, Kepler did get a telescope, and one built by Galileo, but it wasn't just for disecting it.

there's more?


Quote:
In the first months of 1610, Galileo Galilei — using his powerful new telescope — discovered four satellites orbiting Jupiter. Upon publishing his account as Sidereus Nuncius (Starry Messenger), Galileo sought the opinion of Kepler, in part to bolster the credibility of his observations. Kepler responded enthusiastically with a short published reply, Dissertatio cum Nuncio Sidereo (Conversation with the Starry Messenger). He endorsed Galileo's observations and offered a range of speculations about the meaning and implications of Galileo's discoveries and telescopic methods, for astronomy and optics as well as cosmology and astrology. Later that year, Kepler published his own telescopic observations of the moons in Narratio de Jovis Satellitibus, providing further support of Galileo. To Kepler's disappointment, however, Galileo never published his reactions (if any) to Astronomia Nova.[37]
Found it!! He backed up what Galileo had discovered, and more importantly proved some things to himself. What a lucky man to live on the edge of such a breakthrough.

Same page as before.

12) Not optical laws.
13) Confirmation of the "moons of Jupiter"....YES!


Kepler did not have great eyesight, due to his bout with small pox, I think, when he was a youth. He did have about 5 others besides himself observe Jupiter's moons. He had them each record what they saw without telling each other. Later they did a comparison and were able to conclude, with greater confidence, that the moons do exist. This news was contrary to a big demonstration put on by Galileo where the dignitaries, regretably, did not see the moons, so it was an important confirmation.

It's yours crosscountry.

Thank you.

I'm thinking of an extraterrestrial feature. What is it? And for whom is it named?

I missed this earlier. They sure are messed-up over there, aren't they? [I was off by 12 hours. ]

Is it a dunlap feature? [Done lapped over (outside) the asteroid belt.]
