Interesting Things with JC #1813: "Flock Cameras and Your Kids" – Police investigating a missing 13-year-old girl in Tennessee use Flock Safety license plate cameras and a witness's video to follow a lead nearly 300 miles into North Carolina. Meanwhile, parents routinely post children's sports photographs revealing faces, school names, and team schedules, raising an unexpected question about which cameras expose children's identities.

Interesting Things with JC #1812: "John Atkinson Grimshaw" – His parents reportedly threw his paints into the fire, but John Atkinson Grimshaw abandoned his railway job to become an artist. He later painted Victorian streets with such remarkable realism that some of his works used actual photographs beneath the paint.

Interesting Things with JC #1811: "Newton’s 3rd Law & Friction" – Your foot pushes backward against the ground when you walk, but on ice, that same movement can send you sliding. Vehicle tires depend on a similar interaction for traction, while rockets follow Newton's third law without needing contact with the ground.

Interesting Things with JC #1810: "How Deep is the Mariana Trench" — Challenger Deep reaches nearly 36,000 feet beneath the Pacific Ocean, more than three times the depth of the Titanic wreck. In 1960, two explorers reached the bottom, but a fractured window threatened their ability to leave the vessel after surfacing.

Interesting Things with JC #1809: "Physics - Newton’s 1st and 2nd Laws" – A playing card shoots sideways while the coin resting on it drops into a glass. Pull the card slowly, and the coin may move with it. The same physics governs passengers in braking cars and the acceleration of loaded shopping carts.

Interesting Things with JC #1808: "The Assistant That Knows What Not to Share" – Shortly before Meta launched its Muse AI agent, researchers discovered serious vulnerabilities in the systems meant to keep agents isolated. Meta says the flaws were fixed, but agents that can manage accounts, send messages, and act on behalf of users introduce a larger question about how much access they should receive.

Interesting Things with JC #1807: "Creedence Clearwater Revival" – On October 16, 1972, Creedence Clearwater Revival announced its breakup after releasing 7 studio albums in just 4 years. The California band had scored 9 Billboard Top 10 hits without a number one, while growing disagreements over songwriting and creative control divided its members.

Interesting Things with JC #1806: "Andy Green Breaks the Land Speed Record" – Andy Green drives ThrustSSC faster than sound, but misses the official record deadline by 49.5 seconds. Two days later, he returns to Nevada's Black Rock Desert for another attempt.

Interesting Things with JC #1805: "Emmanuel Mensah - The National Guard Mechanic" — In December 2017, 27-year-old Army National Guard mechanic Emmanuel Mensah escaped a deadly Bronx apartment fire, then repeatedly returned to rescue four neighbors.

Interesting Things with JC #1804: "The Paul is Dead Rumor" — On October 12, 1969, a Detroit radio caller claimed Paul McCartney was dead and that Beatles records contained hidden evidence. Fans began decoding songs, album covers, and photographs, turning a bizarre rumor into an international obsession.

Interesting Things with JC #1803: "Kick by INXS" — In 1987, Atlantic Records executives reportedly wanted INXS to scrap their new album, Kick. Manager Chris Murphy refused, and the record went on to produce four American Top 10 hits, win five MTV Video Music Awards, and sell more than 20 million copies worldwide. Behind its success were a taxi driver waiting while a guitarist recorded a riff, an unusual promotional strategy, and a music video inspired by Bob Dylan.

Interesting Things with JC #1802: "James Prescott Joule" — In the 1840s, James Prescott Joule used falling weights and spinning paddles to measure how mechanical work produces heat, challenging a leading scientific theory and helping establish the law of energy conservation. His experiments changed how scientists understood energy, and his name became its international unit of measurement.

Interesting Things with JC #1801: "Projectiles Launched at an Angle" — Throw 2 baseballs at different angles, using exactly the same speed, and both can land at the same distance. Discover why a higher throw doesn't always travel farther and what gravity has to do with it.

Interesting Things with JC #1800: "The Siege of Yorktown" — On October 9, 1781, George Washington fired an American cannon at Yorktown as 8,000 British troops faced a massive American and French army. But the British had an even bigger problem: their escape by sea had been cut off.

Interesting Things with JC #1799: “Horizontal Projectiles” — Launch one ball sideways and drop another from the same height. Ignoring air resistance, they hit the ground at the same time, even though one traveled across the room.

Interesting Things with JC #1798: "Oh, God! starring George Burns as God and John Denver" — On October 7, 1977, George Burns appeared as God opposite John Denver, playing an ordinary grocery store manager suddenly expected to convince everyone that God had actually spoken to him.

Interesting Things with JC #1797: "A Reversible Weakness in Alzheimer’s Gene" – Scientists found a way to reverse some damage linked to the strongest known genetic risk factor for late-onset Alzheimer’s. Instead of changing the gene, they blocked one of the signals it sets off.

Interesting Things with JC #1796: “Free Fall Kinematics” — Drop a baseball and gravity increases its downward velocity every second, but throw it upward and something unexpected happens at the top: its velocity reaches zero while its acceleration does not.

Interesting Things with JC #1795: “Do Redheads Have Special Powers for Survival?” - Tennessee tried to execute Christa Gail Pike with pentobarbital, but she survived. An online theory pointed to her red hair, where real genetic differences involving anesthesia and pain offer an unexpected scientific connection, but not an explanation for surviving lethal injection.

Interesting Things with JC #1794: "Best of Both Worlds" — David Lee Roth was gone, Sammy Hagar was in, and Van Halen responded with 5150, the first number one album of its career, while “Best of Both Worlds” became an unexpectedly fitting title for the band's new era.

Interesting Things with JC #1793: "Velocity & Acceleration vs. Time" — A car can be moving fast with zero acceleration, while negative acceleration can actually make something speed up. Velocity and acceleration graphs reveal what an object is doing through their slopes, areas, and direction.

Interesting Things with JC #1792: "The Compact Disc Era" — CDs went from replacing records and cassettes to dominating music sales, appearing in nearly every car, and then losing the dashboard slot to the digital music they helped make normal.

Interesting Things with JC #1791: "The Night Lake Erie Rose" — In October 1844, powerful winds reversed across Lake Erie and sent water surging into Buffalo, flooding neighborhoods, destroying buildings and driving canal boats into city streets in one of the region’s worst early maritime disasters.

Interesting Things with JC #1790: "Physics: Position vs. Time" — A car moves down a road, stops, or turns around, and a simple position versus time graph records it all, while the slope reveals something the position itself does not.

Interesting Things with JC #1789: "The Lake Michigan Circle" — Drive 1,100 miles around Lake Michigan through 4 states, or board a steamship where an official spur takes the Circle Tour off the road.

Interesting Things with JC #1788: "What the Gateway Process Actually Proved" — An Army officer examined Gateway in 1983. Decades later, his report circulates as CIA proof of manifestation. Somewhere between those two events, an assessment became an answer it never established.

Interesting Things with JC #1787: "Does Apple Cider Turn Into Alcohol?!" – Fresh apple cider starts bubbling. The sweetness drops. Alcohol is forming, and the process may not stop there.

Interesting Things with JC #1786: "9 to 5 - The Movie" – Jane Fonda, Lily Tomlin and Dolly Parton worked inside a fake office built around problems real working women were reporting: low wages, blocked promotions and sexual harassment. The comedy exaggerated the revenge, but the workplace problems came directly from women who had been organizing for change since the 1970s.

Interesting Things with JC #1785: "Why the Desert Floods So Fast" – A desert thunderstorm drops rain faster than the ground can absorb it, sending excess water downhill into channels that were dry minutes before. Runoff from across the watershed combines in arroyos, where floodwater can arrive from a storm several miles upstream that never reaches the people standing downstream.

Interesting Things with JC #1784: "The Hydrogen Peroxide Mistake" – Hydrogen peroxide foams on a scraped knee, but the bubbles don't prove germs are dying. The same chemical reaction that attacks bacteria can also damage healthy skin cells, even as people keep pouring it onto wounds to help them heal.

Interesting Things with JC #1783: "Humanity is Unprepared for AI" – A student spends years preparing for a career while AI changes the work before graduation. Machines can already help people research, solve problems, and produce results, but employers may need fewer workers as those capabilities expand. Students must choose careers and decide when to trust AI systems that can still invent evidence.

Interesting Things with JC #1782: "Why Sound Would Break Apart on Mars" – A human voice travels through Mars’s thin atmosphere, but its higher frequencies move faster than its lower ones. Over 100 meters, the higher frequencies arrive about 17 milliseconds earlier, while the atmosphere absorbs them more strongly with distance. The voice grows quieter as its frequencies separate and fade.

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.
