PHYS178 - Other Worlds: Planets and Planetary Systems

Macquarie University 2008


News

Sketchy answers are now available (see below) for assignments 6-10.
The 2nd midterm, covering Weeks 8-13, will be held on Tuesday 11 November, 9am-11am in E5A 107
The 2nd observing night has been cancelled due to problems with the focusser for the camera and weather. In lieu of the observing exercise (originally worth 5% of your grade) we shall re-weight the other assessment components by a factor 100/95.
Slides for the 2nd half of the unit (week 8 onwards) will appear here as they become available: The same goes for the assignments:


Tutorials start up again in Week 9 (ie. Mon/Tue 13/14 October) and run through to include Week 12. Students will be rostered to talk in one of the weeks and are required to attend each week.

The talk schedule is here (updated Oct 13). Email Mark (wardle@physics.mq.edu.au) if you are not rostered....

The assessment for the presentations totals 20% of your final mark, broken down as follows:

  • tutorial attendance 5%,
  • outline talk and powerpoint slide 3%,
  • presentation 12%.
The presentation mark consists of 7% baseline for an adequate presentation, with an additional 5% possible based equally on the following:
  • sticking to the 5 minute time limit,
  • talk structure,
  • slides,
  • delivery of the talk, and
  • ability to answer questions.

Midterm 1 (worth 25%) was held on Tuesday 16 September, 9am-11am in E5A 107

The slides for weeks 2 onwards are available as pdf files:

Week 1 was a multimedia extravaganza and is not available in pdf....

Description

2nd Semester 2008, 3 credit points.
This unit explores our solar system and the newly-found planetary systems around other suns. We begin by examining the processes that have shaped the marvellous variety of worlds within our own solar system, from the scorched and buckled surface of Mercury to the geysers of frozen methane on Neptune's largest moon, Triton. From this we build an understanding of how our solar system formed and subsequently evolved to become the system that we inhabit today. We turn our attention to the on-going discovery of a startling variety of planets around other stars. These provide a new and challenging perspective on our place in the Universe that is modifying the scientific theories of how generic planetary systems are formed. The unit will highlight breaking news as the unit proceeds. The practical component of the unit includes observing the planets with the telescopes of the Macquarie University Observatory.

Observing Sessions

Observing will be held at Macquarie University Observatory on Culloden Road (see map).

Wear warm clothing as you will effectively be outside in the twilight/dark for an hour. The first block of observing sessions ran 5:30pm - 6:30pm on Monday-Thursday evenings in weeks 6 and 7. The decision whether to go ahead or cancel will be made at 4pm each day (or earlier if it is blindingly obvious we'll be clouded/rained out).

In principle we should be able to catch Mercury, Venus, Mars, Jupiter, Neptune, Pluto, and the Moon. Unfortunately at present Saturn is too close to the Sun to be observed. Here's what we got:

  • Mon 8 Sept: observed Venus, Mercury, Mars, Jupiter (a bit), and the Moon (a bit). Clouds stopped play just after 6pm.
  • Tue 9 Sept: Venus, Mercury, Mars, Jupiter, the Moon, Neptune and Pluto (we assume)!!
  • Wed 10 Sept: Venus, Mercury, Mars, Jupiter, the Moon, Neptune...
  • Thu 11 Sept: Venus, Mercury, Mars, Jupiter, the Moon and alpha Cen (too much cloud for Neptune....)

The second block will be held in the 2nd half of the semester once we have the focusser for the camera fixed.

Assessment

Assignments: There will be 10 mini-assignments based on the lecture material, worth a total of 20%. These will be handed out at the beginning of weeks 2-6 and 8-12 and due at the beginning of the following week. The aim of having many small assignments is to prompt you to be continually engaged with the material. Assignments will be available from this page, as they are set, along with model answers.

Observing: Students will attend two evenings at the observatory in the first half of the semester and undertake a short take-home project based on their observations.

Information about observing.

Presentations: Students will give a 5-10 minute oral presentation on a solar system news item of their choosing, using powerpoint or transparencies. The presentations will be given during the tutorial sessions in the 2nd half of the semester. Advice and assistance with preparation will be available in tutorials earlier in the semester.

Midterms: There will be 2 midterms, each worth 25%, held at 9am on Sept 16 and Nov 11 in the usual Tuesday lecture slot. There is no final exam.

The weighting of the assessments is as follows:

Assignments20%
Observing10%
Presentation20%
Midterms50%

Online resources

There are many, many, useful solar system resources on the internet. Here are some of the ones that I like best. Astronomy news sites (useful for finding talk topics):
  • Spacetoday.net is a good news source, and the news items are an excellent source of talk topics. News items on astronomy and solar system exploration are scattered generic space news. The short summaries are linked to press releases and other news sites.
  • The Universe Today is an astronomy news and information site.

Other Important Information

Generic Skills

  1. Reading, interpreting and understanding reading resources;
  2. problem solving - assignments;
  3. research and presentation skills - oral presentation;
  4. creativity - problem solving approach;
  5. developing an appreciation of the nature of the physical world;

Plagiarism

Plagiarism is defined in the the University handbook ( http://handbook.mq.edu.au/PDFs/2008/ug-plagiarism.pdf) as follows.

"Plagiarism involves using the work of another person and presenting it as one's own. Any of the following acts constitutes plagiarism unless the source of each quotation or piece of borrowed material is clearly acknowledged:

  • copying out part(s) of any document or audio-visual material (including computer-based material);
  • using or extracting another person's concepts, experimental results, or conclusions;
  • summarising another person's work;
  • in an assignment where there was collaborative preparatory work, submitting substantially the same final version of any material as another student.
Encouraging or assisting another person to commit plagiarism is a form of improper collusion and may attract the same penalties which apply to plagiarism."

A general discussion of plagiarism, definitions, examples, procedures that will be followed by the University in cases of plagiarism, and recommended penalties are available from the Student@Macquarie website at http://www.student.mq.edu.au/plagiarism/. The University expects students to familiarise themselves with the website.

Special Consideration

Information about special considerations and student services is available at http://www.physics.mq.edu.au/undergrad/services/.

Student Liaison Committee

The Physics Department values quality teaching and engages in periodic student evaluations of its units, external reviews of its programs and course units, and seeks formal feedback from students via focus groups and the Student Liaison Committee (SLC). Please consider being a member of this committee, which meets once during the semester (lunch provided), with the purpose of improving teaching via student feedback. The class will be asked to nominate two students as representatives for the PHYS 178 unit on the student liaison committee. This nomination process will be conducted during lectures and the lecturer will forward the names to the Head of Department. Summaries of the discussion will be reported to Physics Dept meetings where decisions on actions will be taken. These summaries will also be reported to the SLC as well as being posted.
