Preliminary SSG schedule now viewable.

Signups officially begin on Sunday evening, 8 PM.

For now, however, you can eyeball the schedule, which is linked to the Webcourses home page. I updated the schedule a few minutes ago, and as more SSG leaders report in with their meeting place info, I will continue to update the schedule.

So keep an eye on it this weekend and figure out which SSG you'd like to shoot for.

Mini-homework is ready.

HW 15 is ready to go. There are two calculations and plenty of time to work it out. I suggest the use of paper and pencil for backup, because the scientific notation required by Planck's constant, h = 6.63 × 10^-34 Joule sec, might send your iPhone calculator into FAIL.

Subtotals

For grade calculational purposes, I just set up four subtotals at the top of your Grades page in Webcourses:

1. Subtotal of iClicker2 answered (as of Mar. 11)
2. Subtotal of iClicker2 correct (as of Mar. 11)
3. Subtotal of HW performance (as of Mar. 11)
4. Subtotal of best three out of four midterms

If your iClicker2 answered is 43 or more, you've got the baseline 85% answered. If I were calculating grades today, that would earn you 20/20 for your classwork participation pointage. Cf., syllabus.

The best three out of four midterms slot will remain empty for a few more weeks, naturally.

If anything strikes you as off, save your question until FRIDAY. For now, study and prepare for tomorrow's midterm!

Five SSGs for Tuesday afternoon.

I will be in my office, PS156, in the Physical Sciences Building, at about 7:30 AM tomorrow (Tuesday). You can sign up for one of the five Tuesday afternoon SSGs. First come, first served.

Take a look at the SSG schedule page in Webcourses tonight, and see which one fits your Tuesday schedule.

SSG leader invitations are OUT.

If your Exam 1 + Exam 2 scores >e; 72 points, then you just got an invitation in Webcourses, to become a special study group leader.

Please read and respond ASAP.

Makeshift office hours today.

For today, I will be holding informal office hours in the lecture hall for two hours before lecture begins. SO… from about 11:30 AM until lecture, you can check in and work on HW with me or any other topic.

Homework 9 is ready.

You can now work on homework HW 9. It mainly concerns interference effects, but there is a bit of wavelngth practice in there, too.

We have an important demonstration tomorrow.

Make every effort to be in lecture tomorrow, Feb. 19. We will have a demonstration of diffraction.

It is important because it will be the backbone for a huge amount of physics, starting in this chapter on waves, next unit on electricity and magnetism, then on to the periodic table, chemical compounds, rocks and minerals and oceanography -- i.e., the remainder of the semester!

HW 7 is UP.

Homework #7 is now available. For extra safety, I set it so that you can make five attempts.

As always, read carefully!
