INDEX - Reviews on Astronomy?

-   2456  -  INDEX  -  Reviews on Astronomy?   Astronomers are historians.  Everything they see happened a long time ago.  Like archaeology they are constantly looking at the past.  Of course , none of us can look into the future or we would already be rich.  The past is the best thing we got going for us.  Make good use of it.  Here are Reviews all about astronomy:

-
-  2455  -  ASTRONOMY  -  making sense of science?  Solving the unanswered questions in science may or may not lead to a deeper understanding of the precise nature of reality. If it is a good answer, it should lead to more questions.
-
-   2427  -  ASTRONOMY   -  The new astronomy keeps coming up with new ways to study the Universe using the information in electromagnetic radiation.  Astronomers today are not limited to electromagnetic photons.  Use is being made of neutrinos and gravitons, gravity waves, to make new discoveries in the Universe.
-
-   2409  -  ASTRONOMERS  -  Write like an astronomer.  To be a good writer you need to be more like an astronomer and less like a physicists.  The previous Reviews before this one tried to take the facts as facts and make common, easy to understand, sense out of things.  This seems to me to be an essential element of learning.  If what you write or think is hedgy or equivocal then it becomes hard to understand.
-
-   2406 -  ASTRONOMY  -  The Strange History of Astronomy.  The Universe is the way we see it because if it were any different we would not be here to observe it.  In order to explain black holes and exploding supernova in the most distant reaches of space we need to use quantum mechanics and particle physics.  From the very largest scale to the very smallest scale in the Universe.
-
-   2388 -  ASTRONOMY  -  puzzles to work on?   Puzzles that astronomers find challenging.  The Universe is expanding at an ever accelerating rate due to a vacuum energy in space that we can not identify.  In order to have the effect of gravity everywhere the same,  there must be 10 times more mass than we can identify.  Whatever is causing it the Universe will end cold,  black, with empty space being the winner.

-
-
-  2235  -  Astronomical Distances.  Even our nearest planetary neighbors, Venus and Mars, are tens of millions of kilometers away, so we see them as they were minutes ago. When Mars is very close to Earth, we are seeing it as it was about three minutes ago, but at other times when Mars is orbiting on the opposite of the Sun light takes more than 20 minutes to travel from Mars to Earth.                       
-
-  2172  -  ASTRONOMY  -  Extremes in astronomy.  If this peaks your interest be sure and read this Review.  Extremes in astronomy.  If a human were to become a blackhole he would be compressed to the size of a proton.
-
-  2161 - Great Teachers, Socrates was a great teacher, his student was Plato (B:428 B.C.),  his student was Aristotle (384-322 B.C.) and his student was Alexander the Great.   Socrates taught by always answering a question with a question.  He believed that active participation required that the student figure out the answers for themselves.   Aristotle was a teacher who listened eagerly to others; he freely altered his views when presented with compelling evidence that he was wrong.  He often went back and modified his own writings when he learned more.
-
-  2125  -  Astronomy’s strange discoveries.  The deadliest blast of gamma rays happened on March 19, 2005 in the Constellation Bootes and you could see with your naked eye.  Even though it was 7,500,000,000 lightyears away.
-
-  2081  -  Are we alone in the Universe?  What Carl Sagan, Isaac Asimov and Frank Drake say:
-

-
-  1909  -  My lifetime in astronomy in review.  Years:  1941 to 2017   75 years of astronomy.
-
-  1906  -  A century of astronomy.  Years;  1906 to 2011.
-
-  1898  -  A century of astronomy.  Listing historical milestones.
