Boy Genius Blocks Navy Wireless

Commander Albert C. Gleaves U.S.N. of the Torpedo Station in Newport, Rhode Island, had a problem. The government had installed a new wireless station for ship-to-shore communication but in 1906 they were experiencing interference from a nearby amateur radio operator.
My sign was GR. "GR GR GR," they said, "if you don't stop operating that coil, you will find yourself in the jug shortly." I answered by sitting on the key. I was such a nice boy! - Lloyd Manual, Wireless Age, Dec. 1916.

The Navy investigated and discovered a teenage schoolboy who had converted a hen house into a "ham shack" and equipped it with a home-made transmitter. The meagerness of the radio set startled the professional wireless operators who examined it. A report was filed with the Navy Bureau of Equipment. Some of the components used to build the set were described in The Nashville American and included:

W9GYR

As a young child I can remember my late grandfather operating a ham radio station in Chicago using surplus military equipment that he obtained at the end of World War II. When I received my own amateur radio license about a year ago I began to wonder when he first became involved in the hobby. I suspected that he started before the war so I started to dig through old FCC publications which listed newly issued licenses. I couldn't find a single mention of his name or the call sign that he was assigned: W9GYR.

My first clue to narrow down the search was a website called Old QSL Cards which has a large collection of the postcards that amateur operators send each other to confirm that they had made a radio contact. QSL is early radiotelegraph shorthand for "I am acknowledging receipt" of a wireless message. They had a card from my grandfather that was dated 1939.

This is Arecibo Calling...

"Ironically, the globular cluster at which the signal was aimed won't be there when the message arrives. It will have moved well out of the way in the normal rotation of the galaxy." - It's the 25th anniversary of Earth's first attempt to phone E.T. Cornell Chronicle, Nov. 12, 1999

My estimate of the Arecibo transmission from a couple of years ago.
It looks like we may have missed...

In 1974 a ceremony was held to dedicate a major upgrade to the radio telescope at Arecibo Observatory. As part of the festivities the telescope was used to transmit a message towards Messier 13, the Great Globular Cluster of stars in the constellation Hercules.

Half a Million Years of U.S. History

"Gutzon Borglum's design intentionally left three extra inches of granite on the surface of the sculpture so that nature, in the form of wind and water erosion, would finish carving Mount Rushmore for him over the next 20,000 years." - Matthew Buckingham in Cabinet Magazine

I've stumbled upon claims similar to this a number of times. The amount of stone and the number of years varies. But, I've never seen a footnote or reference to a source that confirms that the meme is true. I found the above quote about 5 months ago in a post titled "Half a Million Years of U.S. History" on the Long Now Foundation Blog. My curiosity compelled me to spend some time digging for an answer. I wrote a reply in the comments section of the blog which was never published. Perhaps I should have waited a bit longer, given the nature of the Long Now project. I'm impatient... So, I'm going to publish what I found here:
