Understanding Bayes’ Theorem

Many people are intimidated by Bayes’ theorem, because it looks like a complicated mathematical equation. However, once we understand what the symbols represent, Bayes’ theorem turns out to be based on the sort of math we all learned in elementary school. To prove it, here’s a video of me teaching Bayes’ theorem to two of my sons (ages nine and ten). If they can learn it, you can learn it!

It’s explained above.

Statistics! They’re every scientist’s friend. But they can be easy to misinterpret. Check out this thought exercise with Hank to understand how some mental kung fu known as Bayesian reasoning can use stats to draw some downright surprising conclusions.

Bach ‘n All

While webmining this evening, I found something a bit different from the usual eclectic stuff that appears on the OOT. More eclectic stuff.


Personally, I’m neither fond of (nor am I a connoisseur of) Classical Music, as the folks who enjoy it are often elite pretentious a-hos in my experience.  On the other hand, I can appreciate the complexity of the compositions and the talent required to perform such works. I don’t have to like it to respect it.

For example, an orchestra can’t perform Ravel’s “Bolero” without a conductor – it’s too difficult a piece; and a retro rock band can’t perform “Surfin’ Bird” without a lead singer. Same difference. The video illustration of Bach’s mathematical and musical genius entertained me.

I guess that makes me an elite pretentious a-ho, too, on
The Overnight Open Thread.

[Update: No offense meant to anyone who actually enjoys classical music. You folks are not the pinky-lifting white-wine-sipping brie-sniffing posers I was referring to as far as you know.]
