Because I have played guitar some 30 years, I have always been interested in guitar construction.   I have multiple guitars because they all have different tones and are used for different things - that doesn't always make sense to people because a guitar is a guitar but I am not even in the top 50,000 guitarists obsessed with tone.    

Eric Johnson, most famous for "Cliffs of Dover"(1) says he can hear a difference in the batteries he uses in his gear - and I believe him.  There are too many instances of elite (yeah, I used that word) people doing extraordinary things to pass it off as placebo effect.

Tangential Science: it's not necessarily science, but it's still funny.

1.  You've all heard that blondes have more fun.   There is even a recurring urban legend that they are becoming extinct, which seems like an effort to get them to have even more fun while they are still around, but what about that most rare hair color, redheads?

Apparently they are in their 50,000th year of not getting enough respect.

Our offices are in a building in sunny Folsom, California, a town made most famous when Johnny Cash had a concert at the nearby prison (*).   It's one of those full service places where they have the phones and the furniture and a kitchen in the middle.   It's obviously more expensive than a regular office lease but the riverboat gambler in me doesn't like long-term leases and I am convinced I could work from my house if my wife didn't say things like, "You can't work from the house."

On Thursday I was walking toward the kitchen to get my 11th coffee of the day when I passed two fellows talking in the hallway.   "No, the cost to run it is $3 million a day," says one.   "That's ..."

I kept walking.

"That's ..."

1.  Greek fire ain't what it used to be.  If you're a student of history, you know that Greek fire  (πῦρ θαλάσσιον) was popularized by the Byzantines, mostly against Arab navies.   We don't know what it consisted of because the recipe was lost to antiquity but it made enough of an impression that various other cultures copied it.   Naptha?   Saltpeter?  No one can be sure.

Greek fire was not an ingredient but instead an entire system.   It required special processing to make and was compressed so that the liquid shot out.  Thus it required expert handling as well. 

Do guys like Bernie Madoff do what they do because of greed ... or ego?    A Florida State professor says it's the latter.    It makes some sense because it takes a certain drive to become CEO of a large company and that takes a certain self-confidence.  

But is it more than just determination and grit and confidence?   Narcissism is the claim Wayne Hochwarter, the Jim Moran Professor of Management in the Florida State University College of Business, is trying to make.
