Hi Ernst, Can you tell us a little about what you want to do with the telescopes? Visual or CCD work? Permanently mounted or portable? Things like that. ...
Carrie, I commend you on your desire to change this "chemistry" and assure you that what you are experiencing has happened to us all. I taught physics &...
Carrie, Your question of motivation is one that all teachers face. You asked, "How do I get rid of the gloom that has infected my second class? Can I?" You can...
Hello Josh, thank you for your reply. visual and portable; that would be the plan now. regards Ernst Wilson Tel : 252-335-3741 Fax: 252-335-3760 ...

An Astroscan telescope is very portable...and under $200 I believe...we use it as a back-up for busy nights in the observatory and with a solar filter for...
... Hi Ernst, For this sort of application, I prefer a well made refractor as it won't need collimation and will cool down quickly and so you can do planetary...
Great suggestions Kendra. I especially like the ending where you say don't beat yourself up. It is one of the faults of good teachers. If you don't care...
Most of the summer workshops at McDonald Observatory do not have a fee attached, and they do not provide transportion. Although the deadline has passed,...

If you haven't seen it yet, I highly recommend you read the new paper by Prather et al. (including the CAE moderator - nice work, Gina) about the positive...
Thanks, Peter! You hit the nail on the head with your comment about one of the key findings our paper was trying to show: that having research-validated...
Hi All, Since Peter's posting about our recent article, "A national study assessing the teaching and learning of introductory astronomy. Part I. The effect of...
Dear Members of the Great CAE Community, We at CAE are very excited to be offering a Tier II workshop in Maui 11-12 July 2009!! So, mark those calendars, get...
Hi- I've been looking for some resources regarding the transparency of Earth's atmosphere, specifically the "cool" fact that we can actually SEE through the...
Hi, Â Â Â I remember a talk any years ago by Frank Shu where he made the claim that the wavelength that our eyes are sensitive to are essentially a function...
Hi all, The Prather et al paper discussed here in recent days certainly was interesting. I'd like to comment on one thing mentioned briefly in the...

Hi, Maybe my info is wrong, but I thought that the Sun gave off about half of its BB radiation in the IR. This wouldn't change anything because the IR is a...
Off the top of my head (so this could easily be wrong): electronic transitions from the ground state tend to be UV, while vibrational transitions of molecules...
Alexander has it correct, for a simple resource try http://www.glenbrook.k12.il.us/GBSSCI/PHYS/Class/light/u12l2c.html also don't forget that some insects and...
Hi! I like the discussion on this and wanted to share a couple of other thoughts regarding "the transparency of Earth's atmosphere, specifically the cool fact...
Hi, David, folks. Here's some thoughts regarding attitude surveys: Some colleagues & I published results of attitude surveys for a physical science course...
Great discussion about the nature of light and Earth's Atmosphere. John Keller, when he was a grad student here at UofAz did a portion of his dissertation on...

An easy way to see what fraction of a blackbody's radiation comes from wavelengths shorter than some given wavelength is given in a table in Allen's...
Evolution still might have had eyes develop that were sensitive in the infrared but they'd have to be darn good distinguishers of the infrared colors because...
Hi, What a fun discussion! Do animals that see in the IR actually distinguish much? The resolution gets worse for longer wavelength light. However, I do...
