Tom Farber, a calculus teacher at Rancho Bernardo high school in San Diego, has come up with a unique way of covering district cuts to his supplies budget. He sells ads on his tests. "Tough times call for tough actions," Tom says. The price of an ad on a Mr. Farber Calc test is as follows: $10 for a quiz, $20 for a chapter test, and $30 for a semester final. Most of the ads are messages from parents but about a third of them come from local businesses. Principal Paul Robinson says reaction has been "mixed," but adds, "It's not like, 'This test is brought to you by McDonald's or Nike.'" I see his point. Being a local business whore is much better than being a multinational conglomerate whore.

While Bill Gates has successfully transitioned himself away from his day job at Microsoft, can Apple do without Jobs at all? Once word started circulating that Jobs may be ill, Apple stock took a considerable hit, dropping more than $10 a share. And when Mr. Jobs was absent from last week's quarterly earnings conference call, the questions started again — and the stock fell again. What does this mean for corporate users of Apple for whom switching costs are high? Can Apple continue innovating in Job's absence?"

And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today."
