The Blackbird is a full-size playable stone violin crafted by Swedish sculptor Lars Widenfalk. The instrument incorporates diabase from his grandfather’s tombstone, with a backplate of porphyritic diabase, both materials more than a billion years old. The design is based on drawings by Stradivarius, but Widenfalk made some modifications to allow it to be played.
The fingerboard, pegs, tailpiece, and chinrest are of black ebony, and the bridge is of mammoth ivory. “What drove me on was the desire to discover the limits to which this stone can be pushed as an artistic material,” Widenfalk said. “At two kilos it is heavier than wooden violins, but it gives you the feel that you are carrying Mother Earth.”

Rabbit Hash, Ky., has been governed by dogs since 1998. The hamlet’s first elected mayor was a dog “of unknown parentage” named Goofy Borneman-Calhoun, who was inaugurated in 1998 and died in office in July 2001. He was succeeded by Junior Cochran, a black Labrador elected in 2004. When Junior also died in office, a special election installed Lucy Lou, a border collie and the town’s first female mayor, who was named Best Elected Official in 2013 by Cincinnati CityBeat magazine and reportedly considered a presidential run in 2015.
The 2016 election went to a pit bull named Brynneth “Brynn” Pawltro, and the town’s historical society also recognized the runners-up, an Australian shepherd and a border collie, as ambassadors who might step in if Brynn were unable to make an appearance.
The current mayor, a French bulldog named Wilbur Beast, took office last year, with a beagle and a golden retriever joining the border collie as ambassadors.
Wilbur’s human, Amy Noland, told NBC News that she ran his campaign because of “all of the negative media that’s out there surrounding America, and the election, and COVID-19, so I guess I wanted Wilbur to be something positive in the news. … He’s done a lot of interviews locally, he’s had a lot of pets, a lot of belly scratches and a lot of ear rubs.”

Eugene Bullard ran away from home in 1907 to seek his fortune in a more racially accepting Europe. There he led a life of staggering accomplishment, becoming by turns a prizefighter, a combat pilot, a nightclub impresario, and a spy. In this week’s episode of the Futility Closet podcast we’ll tell Bullard’s impressive story, which won him resounding praise in his adopted France.
We’ll also accidentally go to Canada and puzzle over a deadly omission.

When the local council removed a bus shelter near the village of Baltasound, on the isle of Unst, Shetland, Scotland, in 1996, 7-year-old Bobby Macaulay wrote to the Shetland Times asking them to replace it — he and his friends had been meeting there to wait for their school bus.
When a new shelter appeared, an anonymous donor added a wicker table and a sofa, and a tradition was born. In time a television appeared, as well as a heater and a carpet. Eventually Bobby’s shelter was named the best shelter in Britain, and now it’s redecorated regularly according to chosen themes (2018 marked 100 years of women’s suffrage in the United Kingdom, for example).

I’ll tell you a plan for gaining wealth,
Better than banking, trade, or leases;
Take a bank-note and fold it across,
And then you will find your money IN-CREASES!
This wonderful plan, without danger or loss,
Keeps your cash in your hands, and with nothing to trouble it;
And every time that you fold it across,
‘Tis plain as the light of the day that you DOUBLE it!
— Charles Carroll Bombaugh, Gleanings for the Curious From the Harvest-Fields of Literature, 1890

Memory feats of chess master Harry Nelson Pillsbury:
“Philadelphia master and organizer William Ruth told Dale Brandreth that he once sat with Pillsbury at a railroad crossing and wrote down the fairly long and different numbers on each of a large group of passing boxcars while Pillsbury attempted to memorize them. Ruth reported to Brandreth that Pillsbury’s memory for the numbers was incredibly accurate and in the correct order.”

{13, 40, 45}
The square of the sum of any two of these numbers minus the square of the third is a square:
(13 + 40)2 – 452 = 282
(13 + 45)2 – 402 = 422
(40 + 45)2 – 132 = 842
