Seen that before. Didn't quite understand the offset wheel effects the first time through, even more amazing that someone could visualise it let alone make it. And also the precision at such an early time. There was going to be a follow up about whether this allowed the Phoenicians to be the "blue water" navigators (ie. out of sight of the coastline in the Med) they appeared to be.

Did that version include the guy who made a replica at home ?

Yes, the fellow Michael Wright who made it used to work at the Science Museum in London, I think.

You may be thinking of something else? The Phoenicians peak comes before this time I think? They would likely have had the knowledge that was used to make this mechanism, though.

This Antikythera mechanism was made in about 65BC and it shows the motions of the "five planets" as they understood them (with the Earth at the center) and it predicted the hour and the color of the lunar and the solar eclipses.

They suspect that the original version was built by Archimedes and this is a miniaturized version built by the Romans, probably. The x-ray and imaging technology they use are masterpieces in their own right.

You are correct. I had it mixed up in my mind with Ancient Worlds presented by Richard Miles which is very good too especially the episodes on the Greeks.

Isaac Newton in his own words / letters

BBC iPlayer - Isaac Newton: The Last Magician (High Definition)

Interesting angle on his secret and long standing study of Alchemey and how he dealt with rivals - could he be the reason why there are no portraits of Robert Hooke ?

Think that human eyes are evolutionary wonders? Then the eyes of the mantis shrimp are at least 4X more wondrous!




Mantis Shrimp Google image search

And check out what they can do with their claws:

They live several long time and have monogamous mating for up to 20 years.

A new NOVA series that is excellent:

Video: Australia's First 4 Billion Years: Awakening | Watch NOVA Online | PBS Video

Video: Australia: Life Explodes | Watch NOVA Online | PBS Video

The series title is "Australia's First 4 Billion Years" but it rally covers the whole earth. Those are the first two episodes.

This is *really* cool!

Water Trapped For 1.5 Billion Years Could Hold Ancient Life : NPR

Water that is preserved since before plant life began - freakin' cool!

Richard Feynman is absolutely brilliant. Watch this and prepare to have your mind expanded.

I don't think I like science as much as I used to. From today's news:
Quote:
Now they're just messing with us. Physicists have long known that quantum mechanics allows for a subtle connection between quantum particles called entanglement, in which measuring one particle can instantly set the otherwise uncertain condition, or "state," of another particle -- even if it's light years away. Now, experimenters in Israel have shown that they can entangle two photons that don't even exist at the same time.
