Interesting Things with JC

Interesting Things with JC #1781: "The Carnyx" – Celtic warriors raised bronze carnyxes nearly 10 feet high, blasting sound through open animal jaws above the battlefield. One surviving boar head had a hinged jaw and movable tongue that could rattle as it played, while seven carnyxes later found at a Gallic sanctuary showed the same instrument belonged beyond war.

Interesting Things with JC #1780: "The Hoover Dam Angels" – Visitors rub the bronze toes of Hoover Dam's 30-foot angels for good luck, unaware that the floor beneath them contains a star chart designed to reveal the dam's dedication date thousands of years in the future. The figures stand above an astronomical record that accounts for the slow wobble of Earth's axis.

Interesting Things with JC #1779: "The Encryption Keys Inside the Camera" – Hackers examine a stolen Flock camera and find an encryption key stored inside the device. Recordings meant to remain protected after theft become accessible, including approximately 1.6 million images and more than 27,000 video clips.

Interesting Things with JC #1778: "The Waffle House Hero" – James Shaw Jr. is trapped inside a Waffle House as a gunman fires through the restaurant, then the shooting stops. Shaw rushes the gunman, grabs the hot rifle barrel with his bare hand, wrestles the weapon away, and later turns the attention on him into more than $240,000 for the victims’ families.

Interesting Things with JC #1777: "Your Mind Controls Your Age" – Adults who viewed their own aging more positively lived an average of 7.5 years longer in a long-running Yale study. Across other studies, people who felt younger also walked faster and declined less over time, while researchers continue to examine how expectations about aging interact with behavior, health, and longevity.

Interesting Things with JC #1776: "Ellen Langer - Counterclockwise" – In 1979, elderly men entered a retreat rebuilt as 1959 and were told to live as though twenty years had disappeared. Days later, researchers measured changes.

Interesting Things with JC #1775: "The Signal Einstein Thought We Might Never Hear" – Two LIGO detectors register the same gravitational-wave signal seven milliseconds apart as two black holes merge 1.3 billion light-years away. The signal lasts about two-tenths of a second, while the instruments measure changes smaller than the width of a proton after decades of attempts failed to detect one.

Interesting Things with JC #1774: "Uncle Sam Day" – Samuel Wilson is supplying beef to American troops in barrels marked “U.S.” when people begin connecting the initials with the Troy businessman they call Uncle Sam. The nickname spreads beyond the barrels, becomes a name for the U.S. government, and eventually turns Wilson’s September 13 birthday into an officially designated Uncle Sam Day.

Interesting Things with JC #1773: "The Clock Behind Instant Replay" – Two instant-replay feeds showing the same moment can reach officials milliseconds apart. Every step through processing, switching, transmission, encoding, and decoding can add hidden latency, so replay has to determine when each frame actually occurred instead of trusting when it arrived.

Interesting Things with JC #1772: "Staten Island Remembers" – At Staten Island’s Postcards memorial, 274 individual plaques face across New York Harbor toward the place where the Twin Towers once stood. Many families represented there received no identifiable remains, making the waterfront memorial the closest thing they had to a gravesite, while a second memorial records first responders who died years later from illnesses associated with World Trade Center rescue and recovery work.
