McMurdo Silver -- A Man with The Knack

In the latest podcast I talked about McMurdo Silver. I noted that many radio pioneers (and many modern-day radio wizards) have very strong and distinctive names. This guy's name is clearly in that category. Here is a 1929 bio on OM McMurdo:

And here is some additional info. From http://hhscott.com/e_h_scott_2.htm:


E.H. Scott had several competitors. The most significant among them was a dashing young genius named McMurdo Silver. Silver was a continuous contributor to technical articles to Radio News magazine (the predecessor of Popular Electronics) throughout the 1930's. He was a polo player, gun collector, and is said to have been quite a bon vivant. Formerly the president of Silver-Marshall, Inc., he set up the McMurdo Silver Corp. and began building custom high-fidelity receivers in competition with Scott.

While good, his receivers were never quite the equal of Scott’s. One of Silver’s most famous owners was Dr. Lee DeForest, inventor of the vacuum tube. DeForest owned a Silver Masterpiece V and praised it in the final chapters of his autobiography. Throughout the 1930s, Scott’s and Silver’s advertisements would do battle trying to “one up” the other’s in technical achievement. Features were stolen and lawsuits initiated. Finally, Scott won the battle and bought out the failing Silver in 1940. Scott then introduced a new, bottom-of-the-line receiver and designated it as the Scott Masterpiece. I do not know if the gesture was meant as a tribute to his archenemy or to rub salt in the wounds. Silver eventually committed suicide in 1947.

Jupiter In the Morning

Jupiter is high in the early morning sky now, and the weather is starting to cool off a bit here. Here is the configuration of the Galilean moons that I saw on September 11. This is from the Sky&Telescope on-line Jovian moon display.

I've even been able to do some "sidewalk astronomy" in the style of guru John Dobson: I have the telescope set up on my driveway, and I offer the pre-dawn dog walkers a look at Jupiter and Galileo's moons. They are always very pleased. It is a nice way to start the day!

Some Encouraging Graffiti

Spotted on a picnic bench in Falls Church, Virginia. Billy's eighth grade science course is focused on physics, so we took this as a good sign.

Pale Blue Dot



I'm reading Carl Sagan's "Pale Blue Dot." I found this beautiful video:

Take a look through the Chromoscope!

On this site you start out with a 360 degree image of the Earth's night sky. You move around using the mouse and you can zoom in and out. (I've zoomed in a bit on Orion in the image above.) Then the fun begins: You can look at the sky in different frequency ranges -- from radio to gamma ray. Very nice: http://www.chromoscope.net/

Climbing a REALLY Tall Tower



This is the kind of thing that causes me to stick with sling shots and wire antennas. The comments added to the YouTube video were kind of funny -- most were in the vein of "Dude, not for a billion dollars!"
