Interesting Things with JC

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.
