This is going to be a quickie—we have houseguests and instead of going through my files for today’s post, I made my SIL watch the first episode of BBC Sherlock. Since this meant I could watch the first ep again, I refuse to think of this as a waste of time, ’cause it wasn’t.
And it does say Random Thursday on the label, so . . .
I’m starting a new knitting project—cover me!
No, nothing so elaborate, just a scarf . . . But if it goes well, a turtle-cozy would clearly be the next logical step.
And that pom-pom on the tank’s gun barrel is simply adorable.*
Why I don’t use my own drawings to illustrate these posts:
Nikola Tesla: half the reason science is as cool as it is
In 1891, Nikola Tesla, who can’t possibly be awarded enough credit for all the amazing stuff he did, invented a resonant circuit-thingie** that can produce high voltage, high frequency, low, alternating current electricity.
If you hook up two or three of these guys—and why wouldn’t you?—you get a Tesla coil.
Tesla coils used to be used in wireless radio telegraph transmissions, electrotherapy, and other various uses until technology marched on and they ended up as special effects props, historical footnotes, and the tools of MIT pranksters.
They can also make music.
The Hungarian Rhapsody one of my favorite pieces, but for those of you who might prefer something a bit more tech-appropriate:
*Don’t worry, Mom, your instead-of-socks birthday present hasn’t been forgotten, but I had to return the book to the library and someone snagged it. I’ve put it on hold again, and once it comes back, I’ll start on your lime green armadillo . . . (ugh)
**Yes, thingie is a proper scientific term when used by someone who might understand circuits in a Mr-Wizard-Explained-It-Best kind of way, but prefers to think of electricity as barely tamed magic that makes things go if you ask it nicely.
