Physics 1120: Electricity, Magnetism, and Optics

Instructor: Steven Pollock and Mike Dubson

This is my all-time favorite image taken by the Hubble Space Telescope - but it is not a picture of stars. It's called the " deep field " image, and it was taken by aiming the Hubble away from the Milky Way, pointing towards a dark patch with no stars....which means (almost) everything you see in that image is a galaxy! It's a profoundly humbling image - each dot is an entire galaxy of stars!

The Hubble Space Telescope is a spectacular engineering success. At its heart, though, is a fairly simple optical imaging system, a telescope built with mirrors. Although by no means the largest telescope in the world, the advantages of being above Earth's atmosphere have provided lots of important data (and popular, beautiful photographs.)

Week 15 Highlights:

Special notes:

New participation (#8) is up - don't forget! (Not for much longer)
Don't forget about the (last!) Tutorial pretest that's now up.
Final exam room assignments are now posted - please see the "exams and grades" link! THEY ARE DIFFERENT FROM BEFORE. It's important that you go to the correct room - please find out well in advance!
I asked in the last "online participation" about a situation where you thought about physics outside of class. Lots of great responses - everyone who said I could make it public (and that they hadn't made it up) I put online, take a look here.
If you are interested in becoming a Learning Assistant next fall, (in Physics II, Calc I, Astronomy, or Biology) check out our information page (Formal applications for LA positions can also be found on cosmos.colorado.edu )

I welcome your comments on the class and this website. Send them to Steven.Pollock@colorado.edu
