Do You Like Physics?

 

If you do,  then we’re sure you’d like our current class in particle physics, being taught at the Senior Center by Rich Noer, an emeritus physics teacher at Carleton.    The photos below show him in action, discussing a slide (1).    Then he explained how one can study the structure of atoms by analyzing their spectral lines, which display the frequencies of light emitted by heated elements.   We see a glowing mercury vapor lamp (2).   Then students are shown viewing, through a prism, the light given off by that mercury vapor .   (3) They see a rainbow pattern from stray room lights,  also a pattern of vertical colors at the bottom right (4).    These vertical colors are different for each known element,  and enable scientists to know what makes up our sun and stars.

We’ll finally discuss the Higgs boson, now receiving a great deal of attention.     Ed

Records Are Made to be Broken

Yes, it’s true;   records don’t always last long.     Therefore no tears were shed when we realized that CVEC set another record for registrations in the current winter term, 227.     This eclipses all previous registrations, for any term,  since our founding in 1997.

Perhaps the credit for this should go to the fine performance of our Curriculum committee.    We certainly have an impressive roster of classes and teachers for this term.     Perhaps it’s because word-of-mouth is still the best form of publicity,  and attendance keeps improving over the years.    Whatever the reasons,  we’re grateful, and we’ll not rest on our oars.     Plenty of work for our board remains to be done.

Here is a picture of one of our most popular classes,  the cinema class taught by Eric Nelson at the Nygaard theater, which totals 60 students.  What people seem to like about this class is the guarantee of new material, the chance to discuss each movie with like-minded friends and an expert such as Eric,  and the comfortable surroundings.   TV just doesn’t quite compete!                       Ed
