Making sense of data is hard. Every new look you take at the same data is another chance to corrupt your understanding, if you're not very careful.

"Which political party is best for the economy seems like a pretty straightforward question. But as you saw, it's much easier to get a result than it is to get an answer. The variables in the data sets you used to test your hypothesis had 1,800 possible combinations. Of these, 1,078 yielded a publishable p-value, but that doesn't mean they showed that which party was in office had a strong effect on the economy. Most of them didn't."

"The Americans might have invented the world's best methods for teaching math to children, but it was difficult to find anyone actually using them. It wasn't the first time that Americans had dreamed up a better way to teach math and then failed to implement it. [...] The trouble always starts when teachers are told to put innovative ideas into practice without much guidance on how to do it. In the hands of unprepared teachers, the reforms turn to nonsense, perplexing students more than helping them."

Fascinating view of the past and very easy to navigate!

You can download pdf maps once you find the time you are interested in :-)

Does anyone know an alternative to http://searspartsdirect.com?  In particular, I'm looking for craftsman lawnmower parts.

I've only ordered from there twice, but neither time things ship as scheduled.  They have a same-day-shipping guarantee that they don't honor when they don't ship.  Turns out they don't stock parts, but just act as a middleman to the OEM vendor.

This is nice.  Not sure why it's a GIF instead of something that someone can pause like a youtube video.  Just means I have to watch it many times to see all changes :-)

This makes so much sense ...

"The more calories we lock away in fat tissue, the fewer there are circulating in the bloodstream to satisfy the body’s requirements. If we look at it this way, it’s a distribution problem: We have an abundance of calories, but they’re in the wrong place. As a result, the body needs to increase its intake. We get hungrier because we’re getting fatter."
