Is This The D'Artagnan Made Famous In 'The Three Musketeers' By Dumas?

Is This The D'Artagnan Made Famous In 'The Three Musketeers' By Dumas?

“I have lost D’Artagnan, in whom I had every confidence,” wrote King Louis XIV to his Queen Consort, Maria Theresa of Spain, after he received news that his right-hand man, Charles de Batz de Castelmore, the Earl of Artagnan, was killed during the siege of Maastricht in the summer of 1673.D’Artagnan would become famous thanks to an 1844 serialized novel by Alexandre Dumas, in which he was instead a young Gascon peasant who becomes a friend to Athos, Porthos, and Aramis in the King's Musketeers and saves King Louis VIII from various intrigues. It was such a hit that it made Un pour tous, tous pour un (one for all, all for one) part of the worldwide lexicon and it's been turned into dozens of films, including its greatest, Richard Lester's 1974 version.

No Danger, How A Stranger Can Be A Game Changer - A New Book About Making 'Small' Talk

No Danger, How A Stranger Can Be A Game Changer - A New Book About Making 'Small' Talk

The future career arc for my house is a library bed-and-breakfast. It will be just like it sounds; every bedroom is also a library, as is the house. Except not a government library, with sterile walls and floors that echo, the whole thing will be comfortable.Because some readers are less social than others, when they reserve a room people will be able to choose to designate Book Club or Book Worm. If they just want to be left alone, they are book worms so they'll get the polite basics. Warm but not outgoing, read in a comfy chair in front of the fireplace in peace. If they are book club, they can talk to me and have coffee and such. 

Medical Marijuana No Better Than Placebo

Medical Marijuana No Better Than Placebo

"Medical" marijuana is legal in many places but often just an excuse to buy recreational drugs, as shown in uptake data that 60 percent of pain patients are older women while 75 percent of medical marijuana prescriptions are for young men.

California Taxpayers Forced To Prop Up $2 Billion Ivanpah Solar Disaster

California Taxpayers Forced To Prop Up $2 Billion Ivanpah Solar Disaster

The Ivanpah Solar Electric Generating System "concentrated" solar thermal plant in the Mojave Desert is by any measure an unmitigated disaster.The party that is now claiming they are rescuing the Ivanpah they mandated to exist was scheduled to be closed this year - because its low costs were always a pipe dream and its maintenance estimates were the optimism no scientists believed.But California ignores scientists. We ignore them about 80,000 Prop 65 cancer warning labels on harmless products, we ignore them on pesticides, and we ignore them on energy.

The Creepy Uncanny Valley Of Targeted Online Marketing

The Creepy Uncanny Valley Of Targeted Online Marketing

Personalized online ads must work for the same reason advertising must work; it wouldn't be a trillion-dollar industry if it didn't work. Even supplements and organic food are only $140 billion, and those are really popular things that don't work. Advertising is not popular at all but good luck succeeding without it.Yet there are limits for what people accept without being uncomfortable. In robots and animation, that has long been termed the 'uncanny valley' - where something is not lifelike enough to look real but too lifelike to be acceptable. Some digital marketing has its own uncanny valley; where it becomes unsettling. Examples are people who say they mentioned something in the presence of their Amazon Echo and then ads on Facebook began to target them.

Teens Are Getting Much Less Sleep Than In The Past

Teens Are Getting Much Less Sleep Than In The Past

A new paper says teens are not getting enough sleep and a lot of parents with teenage children may disagree. Others reflexively blame phones and tablets.It isn't a new concern, though. Nor is technology new in getting blame. In 1905, The Lancet published a study saying that kids in British boarding schools were getting less sleep than was healthy, and the reason was the new popularity of affordable lighting. “Late to bed and early to rise is neither physiological nor wise,” the authors wrote.By the 1950s, the concern was in culture again, this time due to radio and television keeping children up. In all instances, overstimulation, mental health, and poor academic achievement is invoked.

Spring Forward Fall Back: We Hate Changing Clocks But Hate One Change Most

Spring Forward Fall Back: We Hate Changing Clocks But Hate One Change Most

In 1918, with Gen Black Jack Pershing off to France to stop the Germans in World War I, the United States instituted Daylight Saving Time. The public were told it was to save energy sources that would be needed for the war but in June America stopped the Germans cold at the Marne, and then pushed them back toward Germany in July, and by November had ended that war.Yet Daylight Saving Time remained. It still exists 100 years later despite energy savings claims long being debunked, and it being broadly unpopular. Government routinely says they might change it, but when they do they say they would switch permanently to the one everyone actually hates the most, which is the most government thing you will read today. 

What AI Can't Do: Humanity’s Last Exam

What AI Can't Do: Humanity’s Last Exam

By this time 26 years ago, the "Dot-Com Bubble" was ready to burst. People who wanted to raise investor money claimed that they could sell anything affordably on a website; three companies were devoted just to pet food and buying ad space on broadcast television.So-called AI is enjoying a similar frenzy. Though they are still just Large Language Models (LLMs), and the best analogy for that is a fancy autocomplete, they are attracting huge levels of financial investment partly because of the potential and then primarily because people want to make money on stocks, not companies.

Does NBA Income Inequality Impact Team Performance?

Does NBA Income Inequality Impact Team Performance?

A new paper says that players where a few superstars get the money leads to less cooperation and poor team performance. The authors say this salary compression is why teams won fewer games.The authors also suggest that companies should strive for more equity in pay, to increase synchronized effort. Because individual effort by key people isn't enough.They may have a point. The U.S. Army pays everyone, good or bad, the same, and it is the best in the world. But current military and veterans will laugh if a humanities academic suggests it it more efficient or cooperative because of equal pay. Instead, they will tell the stories of all the people their unit had to carry, because it's not a meritocracy and reductions only happen at promotion tiers. 

Dogs And Coffee: Finally, Epidemiology You Can Trust

Dogs And Coffee: Finally, Epidemiology You Can Trust

In 2026, it is easy to feel intellectually knocked around by all of the health claims you read, and all claiming to be supported by science. Weedkillers causing cancer, food coloring causing diabetes, vaccines causing autism, and ultra-processed foods causing everything else are part of a Vast R̶i̶g̶h̶t̶-̶ Left-Wing Conspiracy to make us compliant and Evil Corporations rich.Thinking about the new Trump administration in 2024, Republicans transforming into the 1990s Democratic party - except they haven't banned nuclear power again yet - was not on anyone's Cultural Bingo card.(1)
