The Armonica

The Armonica, also called the glass harmonica was invented by Benjamin Franklin in 1761. In 1757, while in England he attended a concert given on the wine glasses. He thought it was the sweetest sound he had ever heard but he wanted to hear more harmonies with his melody. Thus the Armonica was born and named by Franklin for a word taken from the musical Italian language. It has been said that if the harp is “the instrument of the Angels”, then the Armonica is “the voice of the Angels”.

What’s more interesting is the fact that the refractive index is generally not a constant. Within the same material it can be different for different wavelengths. Usually – but not quite always – higher frequency light experiences a higher refractive index. It gets bent harder. It’s not obvious at the level of classes I teach why this should be so. Since the details aren’t really the key issue, the main thing to remember whether it’s high frequency or high wavelength that gets bent most strongly. It can be difficult to remember, until I remind the class about this:

Say It Isn't So

In the 80s music videos link from the other day I noticed the unsurprising absence of BLOTTO, a favorite Albany (NY)-based band from my high school/ college days (along with Fear of Strangers, aka The Units). So I went and looked for them on YouTube.

I must protest what I found.

This has to be the worse attempt at striking gold in the 80’s punk rock scene.

Punk? Dude, Blotto was not punk. They were a campy spoof-music band. Worst music video ever? Please.

And I was there when they filmed the live footage. (I’m pretty sure I know one of the people visible in the crowd shot at 2:37, though she has kids now and is taking the fifth.)

Metalhead is after the jump. Sarge would always bite the head off of something during the song.
