Ep290: From feathers to flying machines

From feathers to flying machines The early history of flight is strewn with the wreckage of many strange devices… and the people who invented them. From foolish feathered folk flinging themselves from a far, to the powered and controlled flight pioneered by the Wright brothers, we take a look and how we learned to make …

Ep 289: Blast me to the moon

Blast me to the moon We take a look at the very beginning of rockets, including the somewhat obscure origins of gunpowder. The cherry on the top of our explosive cake is a story about how one man tried to build a huge gun that could launch things into space.

Ep 288: From stones to strings to space

From stones to strings to space This week we begin a look at air and space travel. We start our look with the stone age, when we began to learn what we’d need to know in order to fly.

Ep 287: Spider silk?

Spider silk? Brother Phil and I were on the porch the other day, and the topic swung round to the amazing mechanical strength of spider web. He bumped into something about some piece of clothing that had been made from the stuff. After talking about it for a while, it hit me that I didn’t …

Ep 285: A lucky accident

A lucky accident Around the 1950s, many labs were attempting to figure out how to manufacture transistors. Even more exciting was the idea that many electrical components, entire circuits could be put on one crystal. There were several methods attempted to solve the problems that occurred, until one day, in 1955, a lucky accident suddenly …

Ep 284: Back up a bit

Back up a bit A large percentage of the show’s staff all hurt their backs at once—the producer, the audio editor, founder, writer, research department head, and the host. Mind you, those are all the same guy so… We did manage to talk a little bit more about neural networks and early AI research. Hope …

Ep 283: An early AI, and the birth of the transistor

An early AI, and the birth of the transistor Vacuum tubes were all well and good, but they were bulky, hot, power hungry, and prone to failure. Early on, artificial neural networks showed promise, as even if tubes broke while it was running, it would keep working. Meanwhile, the transistor is invented, and the unreliable …

Ep 282: wires magnets and memory

wires magnets and memory We spend some more time with some more vintage tech. This time we look at audio recorded on spools of wire, teletype equipment for input and output, and the magnetic core. Check out the links below to catch some nifty videos of this stuff being demonstrated and explained.

Ep 281: In memory of vintage memory

In memory of vintage memory Before microchips, before solid state transistors, early electronic computers had to hold information somewhere… somehow… Join us as we look at some old methods of storing electronic memory.
