  1. General Rules for Assignments

  2. Please show your working. If you make an error, I can give partial credit if you show your thought process. If you just have an incorrect answer, I can't.

  3. Use words to define symbols being used and to explain your thought processes.

  4. Assignments may be submitted in handwritten format - as long as I can read them!  If I can't read it I can't assess it.

  5. If you need a figure to explain your work, then you must draw it yourself (either by hand or electronically). You may not cut-and-paste figures or text from the lecture notes or other sources. To do so with attribution is pointless, and to do so without attribution is plagiarism.

  6. In accordance with UNSW policy, the assignments handed in should be your own work.

Above left - solid body rotation looks like a spiral galaxy, but we know it is unphysical.

Above right - if the arms move with the rotation kinematics known for stars, then they will rapidly "wind-up" and become so scrambled they will vanish.

Lower right - for the pattern to persist, it must move at a different velocity to the stars, i.e. it propagates as a wave.
