  1. A Greek scientist may have commissioned the device. He may have designed the device. But almost certainly it was built by an unknown Craftsman, or a group of them. I've been watching a series of videos by an amateur clockmaker who is known on YouTube as "Clickspring". He is attempting to replicate the mechanism using as many of the tools and technology of the time period. Something's he has to use modern tools and techniques simply because how the Greek Craftsmen did certain things. One thing he has noticed is the spacing of the gear train makes it appear that this was not a one of device. There may have been predecessor designs and this is a refinement of those devices. It is amazing what one can accomplish with hand tools and hand powered tools

  2.  @EvitoCruor  That's kind of what I think happened to a lot of ancient tools. Valuable scrap was recycled just like we do today. The Antikythera Device didn't appear out of nowhere. There had to be some sort prior use of the different major portions of the device. The thing that is really impressive from the design standpoint is the way the Moon's change of speed throughout it's orbit due it's orbital eccentricity. The thing that is super impressive from the manufacturing stand point is the gear train was evidently made completely by hand. The gears in the device are just under .5 Module. That means from peak to peak it's about 1.5 mm. A 60 tooth gear is under 31 mm in diameter. And these gears were laid out by hand. And filed by hand.

  3. Concrete, what the Panteon is built of. The Panteon's beauty is on the inside.

  4. But I don't like winter. Does that count

  5. A lot of pre 20th century Cairo is built from stone scavenged from Dynastic Eqypt

  6.  @anonb4632  It depends on the setting. In the middle of a Georgian/Victorian/ Edwardian city. No

  7.  @anonb4632  It may not have been the intent of the cities that built them. But it certainly was the architect's.

  8. I'm not going to say beauty is in the eye of the beholder. What I will say is that property, especially in Urban Centers is expensive. Add in construction costs. Full masonary structures top out at around 14 or 15 floors. Unless you want the lower floors totally useless for anything. Steel framed buildings can of course go much higher. Early steel frames buildings were able to be clad in stone, brick or terracotta cotta. Ornamental work could be cast iron or terra cotta. But once you get so high just how practical is that. Especially if the building has no set backs. With set backs if the attachment of the ornamental work suffers a failure due to weathering at least it has some chance of landing on one of the lower set backs than street level. The Prudential building in Boston had a lot of trouble with losing widows. As to most glass boxes I agree they are soulless and depressing. The one exception I can think of is the Pan Am building on Manhatten. At least it's not a square box. Trump's recent Executive order requiring classical style architecture for federal buildings has of course met with disdain from the "art community". In reality the requirement for classical architecture has problems. Two buildings i can think of in DC that shouldn't be in a classical style are the Smithsonian's Air and Space Museum (one of the most visited museums in the world) and Nation Museum of Modern Art. Current architecture need not be joyless. Calatavara's Milwaukee Art Museum is one example. Built as an annex to the original Lake Front structure (a soulless box). The new building if one watches the sunshade opening looks like a bird taking flight. It may not be to everybody's taste. But it is striking. At least the glass box isn't as bad as brutalism

  9. Not enough to account for 55 centimeters.

  10. A computer as we think of one today. No it isn't. It's more of a predictive device than anything else. But for every body who thinks it's just a rich man's toy. But for everybody who thinks it's ",not rocket science". But for everybody who thinks it isn't impressive. I challenge you build one. I challenge you to make the tools needed to build this. I challenge you to figure out how to lay out just one of the gears and file it by hand. That is after you make your own files. Given what we know about the technology and technological processes of the day this was a tour de force of the makers skills

  11. If Yellowstone erupts it would be bad for sure. Extinction level event. No.

  12. One thing about snowflakes. They will melt under a bright hot light.
