All of his videos are behind a Patreon paywall these days, as far as I can tell. He's still working on the Antikythera mechanism, it's just only visible to patrons.

Patreon has gone from helpful support by a few to an exclusive club.

The club is so exclusive it costs $5.

Every time I think about the Antikythera mechanism the quote by Arthur C. Clarke comes to mind "If the insight of the Greeks had matched their ingenuity…we would not merely be puttering around on the Moon, we would have reached the nearer stars." It's a little sensational but also makes me think of what could've been, if certain paths had been realized in past times, and also makes me put the technical knowledge of p…

This realization hit me after spending a few weeks in Italy seeing the remains of the Roman Empire. I had a building sense that they were awfully close to the industrial revolution, that there was no particular reason it couldn’t have happened thousands of years ago in the face of a highly organized, long lived, innovative empire with enormous resources. I think it’s an accident of history that it happened in England…

These were slave societies. Buckminster Fuller enunciated the concept of 'energy slaves', that is each modern person vampires off the energy of certain number of fossil fuel human equivalents. One calculation in the Wikipedia article has 400 energy slaves backing each developed world resident. The most most slave-ridden ancient societies never exceeded 10:1, with most like 3:1. Social progress would need to go in hand with technological progress.

I am ashamed that we think so little of ancient cultures. they weren't stupid. they were as smart as we are, perhaps smarter. they were far fewer in number than we are today, and the library of technology they could draw from to solve a problem was much smaller for them, is all. nothing about the Antikythera mechanism is complex; the math is simple and the construction is that of a machine made many times and made sl…

Scientists build on what they know, not what they speculate. "We" don't look down on ancient peoples, it's just that history didn't show any devices this complicated so this "unique" device has captured everyone's attention. No one is looking down on the Greeks. Ancients humans were as smart as we are, they just didn't have as much data to draw from to create new things or come up with new theories.

Not an accident. Energy. Rome as a meta-organism was limited by available energy- trees weren't enough, and denudation of forests was already a limiting factor. Meanwhile, Britain had plentiful coal in easily-accessible abundance. No point in developing steam and a theory of thermodynamics when you can't use the results.

I thought denudation of forest was a limiting factor in the UK too, indeed a motivating factor for https://en.m.wikipedia.org/wiki/Abraham_Darby_I

It absolutely was. It has been everywhere! The difference being that the UK had coal to fill the need.

Italy does have some coal and Rome at one point had the coal seams of the UK.

Yup. The Romans in Britain did use coal for their hypocausts. But too far away, too little, too late for the Empire at large.

A fun alternative time line to think about would be if the romans had progressed, had depleted all coal and oil resources, leaving us today in a postapocalyptic wasteland, having the knowledge how to build an advanced society, but lacking the ressources…

I would read that book.

"A mote in god's eye", by Niven & Pournelle covers a very similar setup, although not on earth. It's also quite good.

Presumably it would have happened more slowly, as the world population was less then. Though, maybe that wouldn't have actually made that much difference, as the rapid population growth of the last few hundred years is probably largely the result of technological progress (specifically, increases in farm output and modern medical technology). If there had been a population boom during the Roman empire, they might have been able to consume the world's fossil fuel resources pretty quickly, and with predictable results.

The US is a major nuclear power and is one body that actively works to counter-balance nuclear proliferation in the world.

>"is one body that actively works" Not true. Unless you count invading other countries under false pretenses as one. If you think Russia is interested in proliferated I have a nice bridge.

[1] "Preventing the spread of weapons of mass destruction is traditionally a top priority of U.S. foreign policy."

I didn't say anything about Russia.
