I asked ChatGPT to build a rail system for the Midwest that wouldn’t be considered a fantasy.

It came back with nine new regional rail lines and five “higher-speed” trunk routes.

Do we really want 250,000 mirrored satellites in Low Earth Orbit? Hasn't the Starlink megaconstellation already done enough damage?

A US startup plans to deliver ‘sunlight on demand’ after dark. Can it work – and would we want it to?

Satellites beaming sunlight down to Earth sound like science fiction – and they have astronomers very worried.

I'm wrapping up the case study of Bologna's 1970s - 1990s traffic plans, and I think that there are three main overarching policy takeaways:

- a strong initial vision, which is both simple and sophisticated;
- incrementalism, but with strong commitment over time.
- total pragmatism;

#fossilfriday I find early whale and dolphin teeth to be quite beautiful and unusual. This is a lower molar of an extinct, as-yet unnamed simocetid dolphin (?Olympicetus) from the early Oligocene Makah Formation of Washington, USA. Acid prepared; collected by Jim Goedert. 🦖🐬 #whaleontology

A well-preserved molar of an extinct dolphin with dark brown enamel and a tan root; the crown is triangular with several accessory cusps. The lingual side has several short vertical ridges. The mesial edge of the tooth is serrated.

I am writing this because it has swiftly become crystal clear to me that many people have no idea what is happening or how this works. Here is a thread for non-academics to put into context what just happened to Dr. Mark Bray, a fellow historian.

The only king I'll ever kneel to #nokings

A skull of Basilosaurus isis from Wadi Al Hitan, Valley of the Whales, in Egypt. The skull is large (~1.5 meters long) and has a robust, deep snout with a blowhole shifted back over the canine teeth; the eye socket and braincase are small, and the attachment area for the jaw muscles is humongous. The background is black. Basilosaurus translates to "king lizard" - initially misidentified as a marine reptile

Christos Sariannidis found an ancient skull in the cave at Petralona, Greece, in 1960, attached to the cave wall by speleothem. Recent work has established the skull is at least 286,000 years old. It is likely an early member or relative of the Neanderthal lineage. #inktoberLine

In the Samaria Gorge on the island of Crete, Greece, lies a very deep cave with a continual cold spring waterfall. To reach it, you have to swim about 100 meters in 10 degree (C) water. I spent time thinking about hypothermia I was so cold. Nice payoff tho.

Pic of the day

#photography

Walls of the cave direct you to a small bright opening in which a cold mountain spring falls to bright turquoise water.

Along with Denali Mountain and Bryce Canyon, this is the most majestic place I’ve ever been.

My teeth rattling even as I could stand in only waist deep water kept me from fully enjoying it,, but no chance I was missing this just for some discomfort.

It seemed to get progressively colder tho so this is about as close as I got. In later days I’ll post a shot looking back thru the caves. The video I took is really the best indicator of the beauty here but I dunno if I can post that here or not. I may try in the comments later today.

Charlie Kirk’s climate denial was bought and paid for.

Charlie Kirk was a fossil fuel industry plant

Big Oil's money gave Kirk a larger platform to spread baseless climate conspiracy theories—as well as other extremist views.

Picture how big the Hoover Dam is. An absolute unit. The Hoover Dam has a power capacity of 2 gigawatts (GW).

The solar farm that the Admin just cancelled could have produces 6.2 GW of power. That's more than 3 Hoover Dams.

We're spending $20B to bail out Argentina, but they cut USAID down to the bone, causing deaths around the world. The entire budget of USAID, the whole agency, was $21B last year. Shameful.

The Trump administration confirmed that the U.S. bailed out Argentina.

Treasury Secretary Scott Bessent said he had directly bought Argentine pesos in global currency markets in a bid to relieve pressure on the nation’s embattled President Javier Milei, a supporter of President Trump.

The U.S. just bailed out Argentina, Treasury Secretary confirms

The US Treasury has finalized a $20 billion financial rescue of Argentina, including a currency swap arrangement with the country's central bank.
