Dear Physics 24 students,

it turns out that I cannot make my regularly scheduled office hours this
week because I must attend a talk at 4 pm on Thursday.

So this week (and this week only) I will hold office hours on Thursday from
12 to 1:30.  As always, you can drop by any time and if I am in my office
and not in a meeting I will talk to you.
Or you can make a separate appointment.

C.
