On the shifting role of racism in American slavery.
Russ Roberts talks with Michael Munger about a paper Munger co-authored about how white Southern attitudes toward slavery shifted from around 1815 to 1835. Another example of how powerful economic self-interest is in shifting moral beliefs.
humanity had a good run
Yesterday, Elon Musk shared SpaceX’s plan for colonizing Mars. Gizmodo has a good overview of the plan.
SpaceX plans to build a “self-sustaining city” on Mars, according to its founder Elon Musk. But, while we now know a lot more about how SpaceX plans to get to Mars, details about how people will actually survive up there remain sketchy.
Musk dropped the news on Tuesday during an address at the International Astronautical Congress meeting in Guadalajara, Mexico, where he had promised to reveal how the company planned to send people to live on Mars.
“I don’t have an immediate doomsday prophecy,” said Musk, but he noted that he saw only two possible paths forward. “One path is to stay on Earth forever, and there will be some extinction event. The alternative is to become a multi-planetary species, which I hope you will agree is the right way to go.”
Musk says that human flights to Mars could start as soon as 2023. So audacious, I am so rooting for him to pull this off.
Vugar Efendi has made a pair of videos showing scenes from films that have been inspired by famous paintings. The second video is especially good, showing references in There Will Be Blood, Lost In Translation, and a Jacques-Louis David reference from About Schmidt.
That was indeed one of the first things I learned from my driving instructor.
It seems like a really good habit. I’ll give it a try the next time I ride a car.
Hmm. Is that much different than just checking the mirror? I feel like you get the same result.
From the BBC, an hour-long documentary on Ada Lovelace, the world’s first computer programmer.
You might have assumed that the computer age began with some geeks out in California, or perhaps with the codebreakers of World War II. But the pioneer who first saw the true power of the computer lived way back, during the transformative age of the Industrial Revolution.
