A solar cell from powdered doughnuts 2 Jan 2011 | 02:28 pm
Powdered doughnuts are good for you! At least, if you’re interested in solar power. Yes, even you can build your own solar cell using powdered doughnuts and tea leaves. Prashant Kamat’s lab at Notre D...
2 reasons why “Global Warming” is bad science and what a good physicist can do about it 29 Dec 2010 | 10:02 am
Global warming alarmists have spent years blathering on about so-called models and data showing world temperatures rising and the catastrophic consequences. They are obviously full of crap for two rea...
Are we teaching physics students to think like scientists? 27 Dec 2010 | 12:30 pm
I will be at the AAPT Winter Meeting in January where I will give a talk about the conceptual physics course we have been developing (more here and here.) The main point of the talk is to look at the ...
Evaluation of Large-Enrollement Physics by Inquiry 21 Dec 2010 | 05:53 am
A while back, I discussed a plan for my Conceptual Physics courses for non-science majors. Well, I taught the course. It was 48 students and me, and we successfully moved through a lot of the Physics ...
