28, 2015 Mommy, you studied engineering. When I make a right turn on my bike, it leans to my right. When you make a right turn in your car, it leans to your left. Whats the difference?
When your bike turns right, you keep your balance by leaning into the turn. Inertia is trying to keep you going straight and seems to be pushing you > this way, so you lean and let gravity pull you < that way. But I can't bank my car, because it has four wheels on the ground. I have no way to offset what people call centrifugal force. Itll roll my car over onto its side if I take the corner too fast. Oh. Another thing: I was looking at pictures of airplanes with propellers. All the way back to the Wright Brothers, the first props had two blades. Then they had three blades, four blades, and now even more. The engineers must have figured out that more blades are more efficient, right?
Imagine you're a dog walking on solid ground, but you suddenly notice that your paws are freezing and your feet are sinking into soft mud or snow. You've learned how to handle this situation. You react by stepping higher to lift your feet up out of the frigid muck.

23, 2025 Ideally, the messages of television commercials should be directed to the audiences that will see them. During a break for local commercials, viewers in the Carolinas might see an advertisement for North Carolina Blue Cross Blue Shield while viewers in Ontario might learn about Scotiabank. If those ad placements were reversed, the advertising would be useless. The sponsors would get no benefit. But sporting events also include ads that are seen not during breaks but during the actual competition. If a hockey game is being telecast from Toronto, can Carolina telecasters hide the arena's logos and sell the space instead to their local sponsors? They could make a lot of money that way. And yes, it is possible! And it's being done! My new article on Digitally Enhanced Dasherboards explains how I think this trick must be accomplished. I could be wrong.

20, 2025 This is Inauguration Day, but it's also a federal holiday honoring Martin Luther King Jr. He spoke at my college four times beginning in 1957. I was not yet enrolled there for any of those occasions, although I did meet his father a few years later.
There are 1,200 seats in Finney Chapel, and for the first of those appearances an estimated 2,500 people overflowed the building. Students and faculty were fervent supporters of civil rights. Then came the college commencement ceremony on Tappan Square in the spring of 1965, at which Dr. King encouraged the members of the graduating class to be, in today's terminology, woke. A great social revolution was taking place, and they must not sleep through it.

17, 2025 Let's turn back the clock. Way back some 23,934 days back. The year was 1959, and I was 12 years old. My parents and I had driven west, and our vacation trip had reached Southern California.
We were staying at the Lamplighter Motel in Anaheim (above) and had visited Knott's Berry Farm the day before. Now, on July 10, we again ventured out. The famed four-year-old theme park called Disneyland was just on the other side of the avenue.
We ate lunch in Frontierland, but then the heat got miserable around 1:00, I noted at the time. The thermometer reached 103 degrees, a temperature that still stands as the record for July 10 in Los Angeles. We abandoned Disneyland to relax in our air-conditioned motel for four hours. That afternoon, a brush fire broke out 33 miles to the northwest in Laurel Canyon. Residents had only enough time to gather a few belongings before evacuating their homes, many fleeing on foot.
1959 was also the year when the U.S. gained an additional S. and then another one. According to all the newspapers, the 50th state was going to be Hawaii.

recently, Ive noticed that the preferred spelling seems to
include an apostrophe before the final letter. Even closer
inspection reveals that its a reverse apostrophe. Nor do I know why Bluesky seems to think a regular apostrophe is an abbreviation for ’

14, 2025 I saw an instructional video about the standard American accent.
Unlike languages such as German, in which words are pronounced approximately the way they're spelled, English speakers in America need to slur the letters the way their neighbors do. Likewise French speakers in France, where it would be a foe paw (spelled faux pas) to say fox pass.
Of course, this isn't going to happen. Workers and communities in both our countries, Canada's Justin Trudeau has tweeted, benefit from being each other's biggest trading and security partner. There isn't a snowball's chance in hell that Canada would become part of the United States.

As I mentioned earlier, I like documentaries that answer questions scientifically. Specifically, documentaries that dramatize airplane crashes. What went wrong? It's usually possible to sort out the evidence in 15 or 20 minutes and, in the final minute, describe what changes have been made to lessen the possibility of the same things going wrong in the future. A one-hour program can solve three such mysteries. However, TV channels have lots of time on their hands, so usually a single case is stretched out to fill a full hour. That requires a lot of repetition. Several times we hear the co-pilot saying V1; rotate. Several times we hear an alarm sounding. Several times we see an animation of the plane smashing into the ground. Yes, we know, it was a major disaster, but let's find the black boxes and get on with the investigation.
Lately
I watched two extreme examples of this sort of stretching, one about
Amelia Earhart and the other about D.B. Cooper. While attempting to fly around the world in a Lockheed Electra in 1937, Earhart planned to refuel at tiny Howland Island in the south Pacific. But she radioed, We must be on you, but we cannot see you. Fuel is running low. Been unable to reach you by radio. We are flying at 1,000 feet. The plane presumably crashed, but the wreckage has never been found. Military historian Michael Carra became intrigued with the story of an Australian patrol that encountered airplane wreckage in the jungles of Papua New Guinea during World War II. Could that be the remains of Earhart's Electra? Of course not; PNG is 2,500 miles west of Howland, so it would be unreachable if fuel is running low. But we're only asking questions. Folks still wonder about Amelia, so such speculation can still draw interest.
Carra
filmed a two-week expedition to PNG which did uncover some scattered
aircraft wreckage from the war, but not the Electra. He also
painstakingly authenticated the Australian patrol's map, down to an
analysis of the graphite in its pencil notations. Though
interesting, that proves nothing. But now we have a two-hour
documentary of his ultimately meaningless project. In 1971, an airline passenger calling himself Dan Cooper hijacked a 727, demanded money and parachutes, jumped out the rear door, and vanished. Who was he, really? The FBI processed more than a thousand serious suspects. A couple of researchers decided that Cooper must have been one Robert Wesley Rackstraw. They spent five years compiling a list of 93 circumstantial reasons. Those don't prove anything, said the FBI. Rackstraw's attorney called the allegation the stupidest thing I've ever heard. In 2016 the FBI suspended active investigation of the case because the Bureau had more important things to worry about. Nevertheless, documentarians put together a TV program fingering Rackstraw. It was two hours long and included a lot of repeated interviews. No, wait, that was only Part One; a similar Part Two followed. Four hours of television. A tale told by idiots, full of sound and fury, signifying nothing. Bring back stories that come to a satisfying conclusion!

3, 2015 A sports headline told me the Panthers are playing the Cardinals today. Are the Pitt Panthers kicking off against the Louisville Cardinals in another of those bowls? Or are the Florida Panthers skating into the St. Louis Cardinals ballpark for another of those outdoor hockey games? No, this is the National Football League, so its the Carolina Panthers against the Arizona Cardinals. We need more uniqueness among nicknames. Coelacanths, anybody?
