4 Assignments = 7.5% ea., total 30%.
Midterm = 10%+10% (quiz and written problem).
Final exam = 25%+25% (quiz and written problems).
Activity 3% (based mainly on questions you ask in lectures and office hours; as you see these points are aditional to a total of 100% for other tasks; most students won't get them, it's a reward for exceptional involvement and activity.)
Grading of the final score is standard for UofT: minimum % for letter grades (for orientation only, since grades are reported as percentages): A+ 90%, A 85%, A- 80%, B+ 77%, B 73%, B- 70%, C+ 67%, C 63%, C- 60%, D+ 57%, D 53%, D- 50%, F 49% or less.
Office hours: immediately following lectures, other times by email. Stay after lecture, ask any questions you didn't during the lecture (if the question may be of interest to others, I encourage you to ask it during the lecture!). By "any" I mean somehow connected to the subject of the course but not necessarily to the presentation given in the lecture.
Your attendance at the real-time Zoom lectures is very much recommended. The lectures do not follow a single textbook. Occasionally issues are outlined during lectures that aren't fully described in lecture notes (provided in pdf format below). Please take your own notes and ask for clarifications during and/or after lecture. Zoom recordings of meetings will be made available to you via Media Gallery in Quercus.
Final exam is a 2.5 hr exam and follows the format of the midterm. It will take place on zoom like different from the regular lecture, the link will be repeated in an announcement in the week before exam, on 18 Dec 2021, 12:00-14:40.
Preparation for final quiz questions is in this file.
The solutions of the midterm may be useful to review: midterm with solutions (text file).
Sample final exam (2015) is in this file (the exam format was different back then).
You write the written part during a zoom meeting by hand, or if you have
a strong preference type it (but it's more cumbersome to do illustrating sketches that way).
Your camera/mike needs to be ready & showing you
(for proctoring), audio should be muted. You work on your quiz in text editor.
Submission method: taking a snapshot with the phone or computer camera, and submitting your work just like a home assignment, within 10 min after the end of exam. You will edit and submit the quiz file as well (in emergency, any format will do, although we ask you to submit quiz as text file to help with grading.) The Assignment tab in Quercus has been created for submission of files, and allows multiple submissions.
The final consists roughly of about 1/3 of material from before the midterm and 2/3 from the post-midterm part of the course. This way pre-midterm and post-midterm material gets equal weight. No calculators or electronic devices will be needed (your computer will provide a calculator if you need to do simple algebra). A good understanding of the astronomical issues and the knowledge of the Great Moments will suffice.
You decide which part, quiz or written, you do first. It makes sense to start with the quiz, since it usually goes faster and is worth the same as written part. The final quiz will have 60-65 questions. Written part will contain essay-type tasks (there were 2 in midterm, there will be 4 in the final). You may do drawings clarifying your answers. Prepare scratch paper for your written part ahead of the time, and write it by hand. If you have a strong preference, however, you may type and submit your written exam in a file; it may just be more difficult for you to include drawings.
Is the exam open-book or closed-book? Closed books, but during exam you will be able to use self-written note sheets (handwritten only, books/printouts & electronic communication not allowed). Up to 8 pages of handwritten notes are allowed at final exam. This way, you won't have to memorize so much. In fact, you likely won't spend any time searching for the handwritten information, you will simply remember the facts. The dates of events are something that you may want to look up from your notes.
What material/knowledge is required for the exam? In general - all the lectures (notes & recordings) up to the time of exam, your own notes from lectures.
In case of emergency (say, either you or I cannot login to zoom for some reason, you should go ahead, download, do and submit your exam. That's the priority. Submit the makeup exam to email@example.com , and to Quercus assignments if you find the deferred exam tab.
If you don't have drawings in you written problem solutions and do everything in text editor (which you can do) then just submit that exam file. If you write the problems by hand, submmit a separate scanned/photo PDF file with, in addition to the edited exam text file with the quiz. But in emergency use any format you like.
Download this final exam by 10:01 (text file; access blocked before 10:00). Submit this file by 12:40.
At 10:01 you can start working on the exam. If you have questions during the exam, ask them in the zoom chat indicating ASTB03. If you can't connect to zoom, notify prof. by texting to 416-358-4275.
No books or electronic sources of any kind (no googling etc., no phones).
You can do the quiz and written parts in the order you like. The quiz is multiple-choice. Edit the text file and clearly indicate your choice by putting a mark # before letter a,b,c,d,e in front of your choice, e.g. [#b]. [We don't intend more than 1 correct statement, but should there be two acceptable answers, either one will get you a point, so just mark one answer that seems best.]
Writing of the makeup exam ends at 12:30. At that time you should put
page numbers and student number on the handwritten pages.
Within 10 minutes after that time, you should submit to Quercus Assignment
and to firstname.lastname@example.org
(i) the written part collected in one PDF document, just like you do your homework assignment;
(ii) edited quiz file with solutions (put the student number in that file too, pls).
In emergency you may deviate from recommended submission file formats (pdf for written part, edited text file for quiz). [We can read .docx .pdf, and some more specialized formats but would like to avoid sifting through scattered .jpg snapshots.]
Example written problem: Describe the life, work, and the greatest ideas of
Copernicus, in relation to other theories and observations.

Lecture notes are provided here for your reference. They do not replace attending lectures.
From experience, students who do not attend lectures get lower grades because they
are not able to fully understand the contents of the lecture discussed using the provided
concise slides. Lectures are more than the readings from slides.
Coming to lectures, asking questions and taking notes is encouraged, appreciated,
and on some occasion may be rewardable.
The contents may evolve somewhat as the course preceeds, but a prelim.
version of a coming lecture should be available agead of time.
If a full URL to a video mentioned in a lecture note is not given in the text of the lecture, there will be a quoted title (e.g., "Infinite Secrets") that you can find on Youtube. With most browsers and most of my coding of URLs, videos will start after clicking the link in the .pdf file.

File name should indicate the number of the assignment and three last digits of your student number. For instance, assignment 1 of a student with student number 00123456 might be called A1-ASTB03-456.pdf. If you deviate from this scheme, don't worry - it'll just allow us never to mix up your work when we deal with it between me and your TA. Alternative file formats are .txt or .doc/.docx, they're allowed though we prefer .pdf
If the assignment asks for, say, 2 to 4 pages, this means the number of pages in electronic document (pdf) using a typical text file style i.e. single-spaced, reasonable (10pt to 12pt) font size. The count includes illustrations, if any.
Remember to always credit your sources at the end of the assignment in a sepatare bibliography section. Use more than one source, for instance one-half of the references from book(s) if appropriate, and half from the internet pages (state the URL address and name of the page in the literature listing). Do not include pictures in your work that are not in public domain (e.g., wikimedia pictures cited in wikipedia and NASA pictures are public domain, for instance) and for which you don't have copyright owner's permission. That's the general rule in the age of computers. But there is a loophole for us academics. Both in U.S. and Canada the law allows a limited use (citing a part of work) for the purpose of commenting on, criticizing, or parodying a copyrighted work. That's called Fair Use (US) or Fair Dealing (Canada). Use your rights! More info on how not to break copyright in this FAQ.
However, you may commit plagiarism even if you don't break copyright. For instance you cannot claim Fair Dealing if you just rip off a paragraph from author's text literally, without quoting the sourse of this copied parapragh. Even if in the next paragraph you do comment on or criticize that paragraph -- it's the issue of representing someone else's work as your own. So never cut and paste text literally from wikipedia or any other source, unless you list the source in bibliography (literature section). Also, how much do you think we will appreciate your homework if most of it consists of quotations (even if properly credited)? Do your thinking and writing on your own.
Number the references like so: "(...) Aristotle claimed that (...) , which was in
contradiction to the later teachings of Newton ", then list the
literature positions in bibliography:
 Aristotle, "Physics", 400 BC, as quoted by this or that book
 Newton, I., "Mathematical Principles of Natural Philosophy" 1798 (Basel, 5th ed.)
You may alternatively use this style: "Copernicus (1543) claimed that....", and order the references alphabetically. This style looks nicer in print but makes web page citations without obvious main authors more difficult, as you may not know how to call the document and thus where to place it in the list.
In general, use your head, your brain and your mind - a bunch of main citations
may be enough for a simple assignment on one topic only.

Your document should be 1 to 4 pages of your original writing.
Find out and describe how the old paradigm broke down and the new emerged. Start with a very brief summary of ancient beliefs about comets. Two astronomers should get most of the credit for the change. The first was Newton, who corresponded with observer Flamsteed about the shape and dynamics of one comet (what was wrong with the Flamsteed's understanding of cometary paths? What did Isaac Newton propose instead as a trajectory?). The second is Halley, who first applied to many cometary paths the dynamics from Newton's Principia (that he edited and paid for publishing). This allowed Edmond Halley to calculate the perturbations by Jupiter and Saturn of the Great Comet of 1682, its modified orbital parameters, and thus the future time of return of this comet (now called Halley's comet or P/1) in the year 1758. (Give a brief summary of the scientific life of Halley. What is the story of that comet's calculation? Can you find when the historic identification of a past and a present apparition of Halley's comet was first communicated by him to the Royal Society? What were the implications for Halley and for physical sciences in general?)
You will find these resources useful (but do research a wider range of sources and decide
which you find most informative):
(i) Rob Iliffe, "Newton. A very short introduction" (Oxford U. Press, 2007), avaliable electronically from UofT Library (or from the URL cited near the end of lecture notes L9..L10).
(ii) Halley and MacPike, "Correspondence & Papers of Edmond Halley" (Oxford, Clarendon Press, 1932), also avaliable from URL cited in lecture L9..L10.
(iii) web resources such as wikipedia.com, and www.encyclopedia.com, and other.
Ideal length of your report is between 3 and 5 pages. (However, your work is not marked based on the number of pages, but on the contents.)
From chapter 6 of W. Wall's book "A history of Optical Telescopes" (Springer 2018, download from UofT library in PDF form) learn about the issue of the so-called canals on Mars, objects which were seen by many optical observers (who and using what instruments?) in the 19th century, but only some early 20th c. observers and nobody afterwards. Describe the story, relevant other progress of observational astronomy, and implications. What explanation of the phenomenon would you propose to accept; whatprovided the resolution of the issue?
From chapter 8 of Wall's boook learn about the issue of the flawed mirror on the Hubble Space Telescope. Describe the history of how it was discovered, what caused it, and when and how it was remedied.
In both tasks, please augment your presentation with facts provided by at least one online source of your choice (that is, find and cite some more information on the two issues from internet; If the web source is less informative than the book, explain why you think so.)
Please use the relevant chapters (especially 6 and 7) from the book "The Andromeda Galaxy and the rise of modern astronomy" by D. Schultz (Springer 2012), available from UofT library in electronic form, and at least one other source (can be online).
It is OK to discuss ideas on how to solve assignment tasks with other students or friends. It is not OK to copy parts of your assignment from someone elses work, from a web page etc. For example, if two students submit suspiciously closely worded and structured assignment solutions, we do investigate & if a determination of plagiarism is made (differences are superficial), then both students get zero mark for the assignment (one that allowed his/her work to be copied and the one who copied).
Copying whole sentences from internet resources is of course not allowed in assignments and is easily to detect thanks to the same Google that plagiarizer uses to find the aswer ibnstead of understanding the issue and writing about it in own words. If you want to cite someone else's work, use quotation marks for cited statements, then give a reference in your text to the item in the reference list (bibliography). [some of you only provided bibliography but no references in Assignm. set 1 - points will be subtracted for this!]
Of course you don't have to submit your own illustrations, you are free to give reference to figures (citing URL in bibliography), whenever copying the graphics into your work is allowed by the copyright laws. You can always give a link to other people's work published on internet, but not copy and paste their work! There are many exceptions to this restriction, for instance: the so called fair use clause in the U.S., public domain materials, media commons, and all pictures published by NASA (NASA & some other sources grant you the use of their pictures, but do not assume this automatically about other sources).

A new hi-res movie was created from tens of thousands of frames sent to earth from the space probe Cassini, which went into orbit around Saturn. The original frames are black-and-white, taken through filters. The color is restored using a computer on earth. NASA provides the data for such public projects freely on their site. One day the creators of this GIF may create a full-length IMAX movie. Notice that the spacecraft travels through the Saturn system, the planet does not tilt that way itself. Also notice the shadow of the planet on the rings and the thinness of the rings (the true ratio is 10 m : 50000000 m)
[05 Nov. 2014]
A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star, as announced by ALMA team.
HR 8799 is a planetary system. The central colorful blob covering the central star is an artifact of the method of imaging. Three planets have been imaged in 2010 (red dots with arrows indicating the direction and speed of relative motion). In fact, it was the first multi-planetary system ever imaged. Notice the scale in the lower right corner -- the planets are very far from their sun! This planetary system is larger than our (out to Pluto).
[16 Oct. '12] One of the nearest stars (see the table in Appendix to Backman textbook ASTRO) is alpha Centauri, or α Cen. It has just been announced that measurements of its radial velocity with unprecedented precision resulted in a discovery of an Earth-mass planet near to it. Remarkably, a lot of Sci-Fi stories have already been written about humans traveling to a planetary system around α Cen.
[14 Nov '12] A cosmic orphan (of which there are many) has been identified not too far from home: somewhat incorrectly the Telegraph calls it the 1st such discovery of a lonely planet in the Milky Way. CFBDSIR2149 is “homeless” and does not orbit any star, rather it wanders around in the Galaxy alone.
[19 Nov '12] Mail Online reports on an imaging discovery made with the Subaru telescope atop Mauna Kea volcano in Hawai. 13 times more massive (not larger!) than Jupiter, the extrasolar planet is on the border of a class of objects known as brown dwarfs (failed stars). It circles a star kappa Andromedae, which is 2.5 more massive than the sun. This blog is actually a better description of the planet.
