I was a volunteer teacher in Africa from 1988-91.

I would write letter from my village, and it would take one month to get to my family in Canada. They would write a response, and it would take one month to get back to my village. That was just the reality.

Now the village I lived in has a cell phone tower in the middle of it. I haven’t been back, but I am willing to bet that a lot has changed.


I’m in Malaysia right now, which is a majority Muslim country. Restaurants and convenience stores sell beer and other alcohol, but I have seen signs in the convenience stores covering the front of coolers saying that Muslims cannot buy alcohol.

I’m not sure how strictly that is enforced, most of the store clerks and waiters don’t seem to care.



  • Visit the house where Martin Luther lived
  • Buy a Perry Rhodan hefte (an SF pulp serial magazine that has been published weekly since 1961) at a newsstand after not reading one for over 40 years
  • Eat my first currywurst since I arrived in Germany three days ago

That’s exactly right. The proof is quite simple and there’s no reason it shouldn’t be taught instead of just getting students to accept magic rules.


I went through engineering school, and 20 years of work (not as an engineer), before finding a calculus text that explained why the derivative of x^2 is 2x. Along with many practical applications of calculus.

That book was Calculus Made Simple, published in 1914. Thanks, Project Gutenberg!

Edit: derivative of x^2 is 2x. Got my differentiation and integration confused!



I suspect that it was a defense mechanism due to her experience of many older men trying to hit on her. Better not to even open the door.


Have you paid any attention to the political scene in the United States? There is no way that a billionaire could be convicted of any crime. In the rare event that they are charged, they can delay and obfuscate so that they die before any repercussions must be suffered.

I don’t think that the truth of the two-tiered American justice system has ever been so clearly delineated.


I see that the last update was more than 2 years ago. Is it just complete? Or is it being neglected?
