Physics 101 - Astronomy - Spring 2019 - writing assignment based on watching movies in class
Writing assignment:
This course is a general education course, and has a writing requirement.
You will write two papers which will count for 20% of your grade. The topics
will be based on 2 movies which will be shown in class. You must come to class
to see the movies if you want to get credit for the papers. I suggest that you
take notes during the movies. You will then write the paper, based on the
material you saw in the movie. All students are encouraged to see both movies, because they are both
related to the material that we will be covering in the class. If you are unable
to see one of the movies, you will need to write a paper on a topic involving
recent exploration of a solar system object, such as Pluto, Ceres, comet 67P,
asteroid Ryugu, or
Mars, all of which were in the news during the last year or so.
Each paper should
contain at least 2 pages of text (double-spaced), not counting a title page
(which is optional) and not counting any figures (which should be included only
if they contribute to the content and meaning of the paper). If you use material
that is not in the movie or in the textbook, you should include a bibliographic
reference at the end of the paper. Since the paper is written for the class, and
is based on the movie, you don’t actually have to mention the title of the movie
in the paper, unless you want to. Be sure to include your name on the paper
(upper right corner is best, so that you can see it when I return the papers and
spread them out on a table), and include your SIGNATURE beside or underneath
your printed name!
The most effective paper will be an essay similar to a short magazine article, which tells a story about one of the topics of the movie. It should explain ideas for a general reader, not just for your professor (who already knows this material quite well). If you just list a bunch of facts that you got from the movie, you will not "tell a story" and it would not be an effective article. You may want to write about the topic that is most interesting to you. For help on this assignment, you might go to the University Writing Center

The paper is due by the end of class one week after the movie is shown, but it will be accepted any time earlier. Early papers may be brought to class or put in the folder by my office door in Currens 532 (top floor). Please turn in a printed or typed paper. Late papers will be accepted, but you will be penalized 20% of the possible score for each weekday the paper is late!
Physics 101 Astronomy - Movie Schedule
Movie # 1 will be shown Tuesday, February 19, and the paper is due February 26
Movie # 2 will be shown Thursday, April 11, and the paper is due April 18
The second movie is also from public television, and tells the story of the observations of Supernova 1987A, which was a very important event in the recent history of astronomy, because it was the brightest supernova seen for many years, and modern instruments were able to capture important observations which contributed greatly to our understanding of supernovae.
I have written some notes about the movie, to help you with the vocabulary and with a few facts that may not be clear from watching the movie.
Some notes about the second movie, "Death of a Star."
(These are to help you understand the movie; you shouldn't just copy these definitions into your paper.)
SN1987A - the official designation of the supernova, which was the
first one to been seen in 1987, hence the
"A"
Oscar Duhalde - the assistant at the observatory in Chile who may have been the first to actually see
the supernova with his own eyes.
Ian Shelton - the young Canadian astronomer who recognized the supernova and
sent the telegram to Cambridge, Massachusetts.
Las Campanas Observatory - the observatory where the first sighting was
made, located in the mountains in Chile (in South America).
progenitor - the star that blew up (the word actually means "parent"
but the core of the original star is usually left over and forms a new object, a
neutron star). The actual name of the progenitor star was Sanduleak -69 202a
which was a blue giant star and not the usual red giant star that causes most
supernova explosions. It was part of a 3-star system, so there was confusion
about which one blew up.
Neutron star - a compact object about 10 km across (somewhat larger than
Macomb) which is entirely made of neutrons, and very dense like the nucleus of
atoms. These are left over from the supernova explosion.
Neutrinos are very light particles (much lighter than an electron) which
are produced in the supernova. They are very hard to detect, but the underground
detectors in Japan saw 11 of them from the supernova explosion.
Large Magellanic Cloud (LMC) - a small galaxy which is a satellite galaxy
of the Milky Way. The 1987A supernova was in a nebula called 30 Doradus, which
is part of the LMC. It is about 170,000 light years away. This was only visible
in the southern hemisphere; we didn't see the supernova in the USA.
Telex - a type of telegram sent to remote locations using automated
typewriters, used before the internet and more reliable than telephones
(especially at night when nobody is there to answer the phone and most phones
didn't have answering machines or recorders in 1987).
Stirling Colgate - interviewed on a mountain top in New Mexico where he
had an automated supernova search underway with a medium size telescope.

Crab Nebula - supernova remnant from an explosion in 1054
http://en.wikipedia.org/wiki/Crab_nebula
Stanford E. Woosley - Professor at University of California at Santa Cruz
and an expert on supernovae.

Bob Kirchner - the Harvard professor who had the incorrect theory.
The neutrino detector was located in an underground mine in Japan, near a small
town called Kamioka. The facility is often called KamiokaNDE (where NDE stands
for neutrino detection experiment). An upgraded facility is still operating
there, and is now called Super Kamiokande.
See your textbook for more details about this supernova (sections 23.2 and 23.3,
p. 809-823)
I looked for the movie on YouTube, but I did not find one. This is due to the
copyright restrictions on the movie. If someone posts a copy of the video,
YouTube will probably get a complaint from the producers at WGBH (a PBS
television station that made this film) and YouTube removes the video. However,
thanks to a suggestion from a student in the class, I found one at
https://www.dailymotion.com/video/x5w0re0 (Note: there are ads with
this video.)
I did not find a transcript with all the words, so I hope the audio is
audible.
Near the end of class, some students had to leave. The segment starting at
48:15 in this dailymotion version is about speckle interferometry, and did not
contribute to the understanding of the supernova. It turned out to be a "red
herring." Then from 51:22 to the end, they conclude the film with a few remarks
by the major figures seen earlier.
