PHYS 1470 3.0 W11/12 Highlights
3 January 2012 Welcome to the new term and to the
course Highlights of Astronomy!
We talked about logistics and then started the
course. Have a look at the slides. They are uploaded in PDF format.We
started on Chapter 1. It is advised to
be prepared for the lectures by reading the material that will be
covered in class in
advance. Please read all of Chapter 1. We also learned about a scaled
version of the solar system where the sun is shrunk to
the size of 1 cm. Do you remember where the planets are located
in such a scaled-down solar system and how big they are? Where is the
nearest star in such a system?
5 January 2012 We continued with Chapter 1.
10 January 2012 We continued with Chapter 1.
2012 tutorial We had our first tutorial and covered the
subjects of RA, decl, HA, LST, the vernal equinox. What are RA and decl.
of the vernal equinox? What are RA and decl. of the autumnal equinox?
What are RA and decl of the sun on 21 September 2012? 12 January 2012 We had a fun quiz and started with Chapter
17 January 2012 We continued with Chapter 2.

2012 tutorial We talked about E_kin and E_pot, v_escape
and v_c, the gravitational force and the centripetal force. Then we
looked at some of the review question. 19 January
2012 We started with Chapter 3 and are now on p
78. Please note, that the slides sometimes cover more than the book,
particularly when it comes to equations and computations. We had our
first clicker quiz. The .pdf versions will be put on the web. 24 January
2012 We continued with Chapter 3.
2012 tutorial We did some calculations based on Wien's
law and the Stefan-Boltzmann law.
2012 We started Chapter 4.
2012 We finished Chapter 4 and started on Chapter 5. We are
now on p. 139. We also figured out quantitatively
how large the contribution of the greenhouse effect is to the mean
temperature of the Earth. We
learned about the moon, looked at the characteristics and singled out a
few of them. We got to know about the most likely scenario for the
formation of the moon. We then started on Chapter 5 and learned about
Mercury. 1 February
2012 tutorial We
did some clever math to see the radial dependence of the tidal force
between the Earth and the moon. We recollected why the moon shows us
the same side and why it spirals away from us -- slowly, very slowly
so. 2 February
2012 We learned
everything about Mercury, its origin, the 3-to-2 spin orbit coupling
and the reason behind it, its interior and its surface. We
looked at Venus, its
surface and the greenhouse effect and its strange retrograte spin. Then
focussed on Mars. We learned about the landscape of Mars, the
atmosphere and that it is snowing on Mars, discovered with York's lidar
system that was installed on the Phoenix lander. Look
at the avalanch
recorded recently by NASA. 7
2012 We started on Chapter 8 and
covered Jupiter and its moons. Click here to see the red spot of Jupiter
in action. We are now on p 230.
2012 tutorial We computed the energy release
of an asteroid crashing on Earth and looked at some review questions.
2012 We covered the rest of Chapter
8. We learned about the ring structure of the Jovian planets,
talked about Saturn, Uranus and Neptun, and focused on Titan and
Triton. Click here to see the video of Huygens' descent on
2012 We started on Chapter 6.
2012 tutorial We talked about assignment #1
2012 We finished Chapter 6. The
marks you have obtained so far are on the web. Have a nice and productive Reading Week!
2012 We started Chapter 7. 29
2012 tutorial We looked at some review
questions and did some calculations.
2012 We looked at the three steps
of how hydrogen is fused into helium: the proton - proton chain. We did
some calculations about the energy release through hydrogen burning.
2012 We finished Chapter 7 and
started on Chapter 8.
2012 tutorial We talked about lab assignment
#1 and covered some questions from Chapter 7 and 8.
2012 We finished Chapter 8 and have
covered Chapter 9 up to p 289. All the marks so far are on the web. Attention: The midterm-makeup exam
is on Monday March 12 at 4:00 to 5:15 pm in Farquharson 020. 13 March
2012 We worked on Chapter 9.
2012 tutorial We talked about the midterm
2012 We finished Chapter 9 and
started Chapter 10. We are now on page 320.
Attention: For the Lab #1 assignment, you do not have to do any
observations with a telescope. The
last sentence of the first paragraph "While your analysis...."
should be deleted from the Lab-exercise 1
assignment sheet. An updated version without that sentence is now on
2012 We covered a good portion of
2012 tutorial We talked about assignment #2
and black holes.
2012 We finished Chapter 10 and
started on Chapter 11. We are now on p. 380. The Lab #2 assignment and
an updated table of the marks so far obtained are now on the web.
2012 We finished Chapter 11 and
covered a good portion of Chapter 12.
2012 tutorial We talked about lab#2 and the
2012 We finished Chapter 12 and
Chapter 13. That is the end of the coourse. The marks obtained by you
so far are on the web. See you
for the final exam on 14 April.
