@markyzaguirre @StephenFleming Most generational divide categories are somewhat arbitrary, but the Baby Boomers are the one generation with very clearly a huge difference in life experience from being born a year or two on either side of the starting year. We should keep the traditional definition of Boomer.
I love this map of housing built before 1919. It largely tracks economic development (Greater Paris, the West, the Alps, the South-East...) But there's one nasty blue scar in the North-East that looks eerily familiar...
Patriotic programmers will celebrate the nation’s real milestone anniversary in 2032.
We should do an even bigger celebration for America’s 256th.
@Steinernomics The most essential good is food. The largest famines in the post WWII era occurred in countries that had government socialized food systems, often when they were most socialist (China, N Korea, Cambodia, USSR). Meanwhile, famine is essentially unknown in free market nations.
@DrPhiltill For those unfamiliar with the story of the smuggled Surveyor 1 flag, thewebsite for Hughes retirees (some of whom built Surveyor) has details of this and other company accomplishments. hughesscgheritage.wordpress.com/2016/03/11/sur… This is part of a long tradition of smuggling things into spacecraft.
The Founders on Twitter Washington: -never tweets himself -account curated by staff -usually Hamilton using the account -doesn't follow anyone -only tweets official statements
@bendreyfuss As I recall, he was a former military pilot, reduced to flying crop dusters. And they didn’t have to train the volunteers how to *land* the F-18s… (Another quirk is that the DoD refused to support filming it and so every fighter jet from every country is the same model F-18.)
@DJSnM Suddenly it makes more sense that they measure the energy content of food in a “bomb calorimeter.”
If your town has a local regulation about whether you can set off fireworks this weekend, that’s an Ordnance ordinance
The extinction of the dinosaurs is technically the highest ratio of birds killed with one stone.
@AsteroidEnergy In what sense does “self-plagiarism” legally exist? You might assign copyright for something you wrote to a publisher, so you can’t reuse it. A publisher may ask that all submissions must be new. But these aren’t quite the same thing as the action called “self plagiarism.”
Some AMC Theaters are screening Citizen Kane this weekend to commemorate the 85th anniversary of its premier. If you’ve never seen it, here’s your chance to watch one of the great classic movies on the big screen. Space tie-in: Chelsey Bonestell painted some of the backgrounds.
One of the weird quirks of geography is that the Greet Lakes, some of the largest freshwater lakes in the world, are fed from a comparatively tiny watershed with no major rivers. In many places it’s only a day’s walk from lakeshore to headwaters.
There is only one point on Earth from which when it rains water can flow into three different oceans (Pacific, Arctic, and Atlantic). However, Canada and the USA both lay claim to the title. But which peak is the victor? Is it American or Canadian? 1/n
@peterrhague Three cheers for the eclipse predictors. And if you haven’t had the opportunity to see a total eclipse yet, it’s absolutely worth traveling for.
If you have any doubts: The people who say Earth is a chubby spheroid with equatorial radius of 6378.137 km rotating every 23 hrs 56 minutes can predict decades in advance where and when to go to see an eclipse. People who say Earth is flat can’t say when it gets dark at night.
Once something becomes a Fixed Cost in your household -- housing, car, kids' activities -- it is nearly impossible to cut back on This is why I'm so relaxed about buying a random dinner but very careful about adding new Fixed Costs, which must earn their way into our spending
@jrockandrollt I think I could never have predicted a situation like “we had to put down our family’s robotic capybara for safety reasons, ” and yet I feel if you had told Douglas Adams or Phillip K. Dick this is what life will be like in the 2020s they would have nodded and been unsurprised.
@JesusFerna7026 As an American, it is always sobering to wander a small British or French town’s square or park and see the long list of names of men lost in WWI and the much shorter list of names appended for WWII. We often focus on the War we were more engaged in and forget WWI’s devastation.
@BDHerzinger I love that it specifies that it’s a 1:1 scale decoy. It implies discerning buyers know to watch out for scammy sub-scale decoys sold by off-brand websites. But it also makes me wonder if the enemy could be deceived by a tank company of 75% scale decoys at a lower cost.

People love to hate on Lockheed Martin, but where were they the past 100 years? Where were those people who are mainly from CA who only really invested money inside that state? It was Lockheed Martin that built factories across rural America, paid a great salary to tons of combat veterans & gave them stock in addition for their contributions to the company. They are by far one of the greatest companies in the history of humanity & thank god they are American! Lockheed Martin is America & stands as one of the great symbols & icon of classic Americana! 🇺🇸🇺🇸🇺🇸
These are kid friendly videos & very purposeful. It's a nesting approach designed to get the younger generation interested in manufacturing. This accomplishes that in a way that is easy for gen z to understand. Lockheed will hit 100 years of operation on the 13th of December of
