Thanks very much! best, Jatila ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~* Jatila van der Veen, Ph.D. Lubin Group, 2225 Broida Hall Department of Physics ...
Dear Everybody, I have just been hired as an assistant professor at Purdue University, the Calumet Campus, 50% in the department of Education and 50% in the ...
Many of you probably saw the posting below on today's astro-ph listing, but I thought I'd point it out for those who didn't. My personal opinion is Bravo! I...
While by itself the magnitude system can add to student confusion and frustration, one major advantage is that it introduces (or reinforces) the concept of a...
... It is _close_ to how the eye works. I remember bringing this up with a biophysicist and they said the eye is probably closer to a power law response than...
I have mixed feelings on dropping magnitudes. Several years ago I tried dropping magnitudes from my stellar astronomy class (with lab). Even using a textbook...
I first taught the magnitude system using all of the relevant equations in a calculation-based astronomy course. I found that a significant number of students...
Thanks J.Sudol, very thoughtful. Not a simple problem. Some of the same isssues arise in teaching decibels as a measure of intensity in the physics of sound....
I know the history of it, but that doesn't mean that now that we know that the colors correspond to temperatures we shouldn't set the axis aright. ... From:...
I tend to agree with Jeff. In fact I think it would be easier to switch the temperature direction (and change the wonderful mnemonic or just specify the...
True, the magnitude system is "backwards" (lower numbers are brighter). True, temperature decreases to the right on the HR diagram (at least in the classic HR...
I can't image why you would want to eliminate the instructionof magnitudes from any astronomy course. Simply because most of the students don't know what...
My apologies for some of the run-on words. Apparently, Yahoo's Beta Rich-Text Editor is need of further testing. I've reposted my remarks below: I can't image...
As a radio and infrared Astronomer by training, I couldn't disagree more with the idea that there is anything fundamental about magnitudes. All Astronomers...
I hope no one takes my post personally. It wasn't directed at anyone in particular but is just an expression of my zeal for the subject. My apologies for any...
Thank you, Alexander Rudolph, for saving me the trouble of explaining that there is nothing fundamental about magnitudes, and that anything that can be done...
Neil, third-person rebuttals are impersonal with the person to whom the rebuttal is directed at left feeling a bit alienated. Based on your opening sentence,...
To clarify this comment in my original post "The Magnitude System is the fundamental method by which astronomers determine an objects brightness and hence, for...
I hope everyone on this forum is aware that e-mail is a tricky medium for discussion. There is no nuance or non-verbal cues to help smooth over what can seem...
I think this thread has been mostly civil. However, reading over the progression of the thread, there were some statements that, in retrospect, I should have...
Hey All,  I've thoroughly enjoyed reading this thread, and hope it continues! I'll add my two cents (well, maybe just a hay-penny...)  There are clearly...
For me, Rajib gets to the heart of matter. I'll add my thinking: When we discuss teaching astronomy, I think we are mainly talking about Astro 101. The vast...
Dear All, Alex, thank you for your very insightful comments on email communication. I know I have said things in email that sounded to the reader very...
Paul, you are doing a fantastic job!! Your Humble Moderator, Gina ______________________________ Gina Brissenden Program Director NASA Center for Astronomy...
Greetings all, I am looking for any activities/exercises publications similar to the great 'Activities Manual for Life in the Universe, 2/E' (by Prather,...
I think there is an interesting distinction that can be found earlier in this thread if you read closely. It's implicit, and because of that I believe it was...
I've been retired from teaching AST101 for a couple of years, but my teaching career covered from the mid 60's to early 2000's including a large commitment to...
A while back I had posted a question dealing with the kinds of students that we have in our classes. Adam makes the same point again. Are we teaching future...
I've been finding the discussion in this thread very helpful in clarifying my own thinking - especially regarding who I think my intended AST 101 audience is. ...
