Southwest airlines circa 1972

Remember what it was like before Southwest Airlines?  You didn't have hostesses in hot pants.  Remember?

And here I thought Southwest was famous for having no frills, low low fares, a simple web interface, happy employees who dress as casually as they want, and clever logistics to keep turnaround times low. 

Frills are clearly evident in this video, and yeah, the casual dress doesn't appear to be part of the original plan.  I didn't even know the airline was that old.

Ant problem

Suppose your house (say, the one I'm living in now) has an ant problem.  Suppose you toss some food out and the ants get to it.  The ants take your food back and turn it in to more ants.  How many more ants?

Energy conversion across trophic levels in the food chain is around 10%, an ant in this part of the world weighs around 0.2mg, and a typical apple weighs around 300g. 

So... if the ants eat the whole apple, they can use it to make 150,000 more ants.  Fucking ants.
