    People are tempted to speak only about the features of their product. Don’t leave out an important pitching factor when you do so. Think of Steve Jobs introducing the iPod Nano. He didn't tell us it had 16GB of memory. He said: "Imagine a thousand songs in your pocket."

    Why did the Industrial Revolution occur in Britain? In 1600, it wasn't the only place in the world that seemed a candidate for an acceleration of innovation. Here's a thread on two of the other promising locations, one of which might surprise you...

    1/ Did you know that Vannevar Bush (you know, the guy who helped enable everything from radar to the manhattan project, the NSF to memexes) wrote an autobiography? Turns out that yes he did, it's been out of print since the 70's, and it's *excellent* BOOK REPORT THREAD

    My latest post, on the sixteenth century's forgotten Golden Age. Not the one in England, nor the Dutch Republic, nor even China. But the one in Morocco.

    Dystopia exists. The abandoned apartment block- Ponte City, Johannesberg. In the 1990s gangs moved in & it became a symbol of crime & urban decay. The core filled with refuse 5 stories high. In the 1990s there were plans to turn the building into a highrise prison. Thx@Oniropolis

    Infectious disease is a multi-front war: Sanitation removes germs from the environment. Vaccines provide immunity. Antibiotics fight active infections. But historically, what mattered most? I was surprised when I started digging into the data:

    I asked the head of scientific affairs for the dietary supplement trade group to refer me to a scientist without ties to the industry who believed the health claims made on dietary supplements were meaningful. She couldn’t.
