I tend to notice it at about the 2/3 - 3/4 mark.

I call it the "post midterm doldrums."

I don't know for sure but here's what my gut tells me. Yes you technically should be able to detect cosmic rays, or rather cosmic rays would Tue, 03 Nov 2009 19:37:18 GMT drcreneejames http://tech.groups.yahoo.com/group/astrolrner/message/2893 http://tech.groups.yahoo.com/group/astrolrner/message/2893 Hi, all - Does anyone know whether the CCDs in store-bought digital cameras can detect cosmic rays? Once upon a lifetime ago, cosmic ray hits on the CCD chips Mon, 02 Nov 2009 14:07:43 GMT Speck, Angela http://tech.groups.yahoo.com/group/astrolrner/message/2892 http://tech.groups.yahoo.com/group/astrolrner/message/2892 We're doing research on the CUES thing I posted earlier Will keep everyone up to date on results as we get them....

Knowing what research is going on and how it is being conducted allows us to modify projects we are working on and also lets us explain a Sun, 01 Nov 2009 20:43:33 GMT Alexander L. Rudolph http://tech.groups.yahoo.com/group/astrolrner/message/2890 http://tech.groups.yahoo.com/group/astrolrner/message/2890 For anyone in the SoCal area, I am giving an invited talk on our national study on Astro 101 teaching and learning (featured in our Physics Today article) on Sat, 31 Oct 2009 18:31:58 GMT Shawl, Stephen http://tech.groups.yahoo.com/group/astrolrner/message/2889 http://tech.groups.yahoo.com/group/astrolrner/message/2889 I'd like to see researchers use astrolrner because the rest of us are then exposed to their ideas as they develop. And they might gain from comments we make.

Astrolrner is an important Fri, 30 Oct 2009 13:20:26 GMT Eric Brunsell http://tech.groups.yahoo.com/group/astrolrner/message/2886 http://tech.groups.yahoo.com/group/astrolrner/message/2886 "student interest is a better indicator of success" Student interest is a huge component of achievement. The first step in creating a conceptual change is for Fri, 30 Oct 2009 00:07:14 GMT Gina Brissenden http://tech.groups.yahoo.com/group/astrolrner/message/2885 http://tech.groups.yahoo.com/group/astrolrner/message/2885 Hi Jim, I'm sure many of us on Astrolrner@CAE are very much looking forward to your insights into online teaching-we increasingly hear from our workshop
