“To exchange one orthodoxy for another is not necessarily an advance. The enemy is the gramophone mind, whether or not one agrees with the record that is being played at the moment.”  --George Orwell


 “But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship.  Voice or no voice, the people can always be brought to the bidding of the leaders.  That is easy.  All you have to do is tell them they are being attacked, and denounce the peacemakers for lack of patriotism and exposing the country to danger.  It works the same in any country.”  --Hermann Goering

testmake creates multiple forms of a test

            New version 2.0: calculates numeric answers and decoys with arbitrary arithmetic expressions that you provide

testmake takes a text input file of multiple choice questions and answers, and produces multiple versions (“forms”) of the test. 

New version 1.3: scangrade simplifies Scantron grading


Windows versions:      scangrade.exe  testmake.exe  

Linux and Mac versions available on request.  Please let me know.

Slow motion at a trillion frames per second, literally. You can see a light pulse travel across the table, and through a bottle.  The video at the bottom is the best, including both slo-mo scenes, and describing how it works.  There are also FAQs.

The purpose of the “Funky” series of documents is to help develop an accurate physical, conceptual, geometric, and pictorial understanding of important physics topics.  We focus on areas that don’t seem to be covered well in most texts we’ve seen.  The documents are intended for serious students of physics.  They are not “popularizations” or oversimplifications, though they try to start simply, and build to more advanced topics.  Physics includes math,  and we’re not shy about it, but we also don’t hide behind it.  Without a conceptual understanding, math is gibberish. 

These are all works in progress.  Please send me your comments.  Now with PDF hyperlinks and physical constants!
