Anyone who has chuckled over the various versions of the “you have two cows” political system paradigm will enjoy this math paradigm.

Teaching Math in 1960:
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?
Teaching Math in 1970:
A logger exchanges a set “L” of lumber for a set “M” of money. The cardinality of set “M” is 100. Each element is worth one dollar. Make 100 dots representing the elements of the set “M.” The set “C,” the cost of production contains 20 fewer points than set “M.” Represent the set “C” as subset of set “M” and answer the following question: What is the cardinality of the set “P” of profits?
Teaching Math in 1980:
A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment: Underline the number 20.

Of course the temptation is always to personalize something like this, and I have to admit that I did learn math with the 1970′s system. That’s actually pretty close–hee, hee, it’s a great parody. Now that I am myself a teacher, must also admit that I use the 2010 method with my students. Pero mis estudiantes son los madres de los que estudian matematica. Their children speak perfectly fluent English and often help their parents translate.

But then, a few things started to fall into place. First, miraculously, an exhaustive examination of the Obama campaign’s cache memory turned up the information that the senator had actually been in the camel’s hometown of Wajid, Kenya on 8/27/06, the exact day when the official campaign photographers were so very attentive and the rest of the press said the senator was busy getting his African sartorial lesson.
What is he saying to the crowd? According to the purloined email, Obama is shouting, “Can you eat camels?” And the crowd is shouting back, “Yes we can.”
Karson’s underground paper, the Yeti, is currently unavailable online. I was able to read a few excerpts of it in other publications, though, which were unexpected enough to make me relax and crack a smile, but too heavy-handed to approach giggle status on my humor scale. I suspect Karson’s best writing is yet to come when he matures a little and learns a more subtle touch.

It has long been suspected that the government has been using satellites to read and control the minds of certain citizens. The use of aluminum helmets has been a common guerrilla tactic against the government’s invasive tactics. Surprisingly, these helmets can in fact help the government spy on citizens by amplifying certain key frequency ranges reserved for government use.
