| 1303569 | 2012-09-26 09:52:00 | That is absolutely well worth watching if it is about "Decoding The Antikythera Machine". It was a pity there was no real speculation as to how the Greeks were able to divide circles so accurately or how they were able to make hardend steel files to cut the gear teeth, or even to describe in detail their maths calculation processes. Edit: it is the machine tools they would have had to have made first in order to make the computer that intrigues me |

But I agree, he makes a comment about the greeks not being able to machine it and then pulls out a file, I laughed out loud. Obviously even scientists don't realise how much metallurgical science and precision machining goes into making a simple file. The humble file is a work of engineering art that goes mostly unappreciated. |

| 1303571 | 2012-09-27 00:31:00 | Good point about the file. But even with a good file, fancy being able to file dozens of tiny teeth perfectly evenly! Amazing. | linw (53) | ||
| 1303572 | 2012-09-27 00:49:00 | This is really brought home if you have ever tried to cut saw teeth by hand from scratch. Edit: the history of machine tools and measurement is fascinating. A whole hierarchy of basic foundations like establishing a flat surface and a straight edge has to be achieved before much progress can be made. |

| 1303574 | 2012-09-27 03:29:00 | Ah, yes, momentarily overlooked that:) | linw (53) | ||
| 1303575 | 2012-09-27 03:48:00 | Or someone had gone back in time with that knowledge. | Driftwood (5551) | ||
| 1303576 | 2012-09-27 09:28:00 | Nah! They were just a lot smarter than most think. just look at their statues some incredible stuff in their later period! Iwould guess they wern't cleaning up the bronze castings with hard stones. | PPp (9511) | ||
| 1303577 | 2012-09-27 12:11:00 | A couple of the statues found in the same place as the device were, indeed, stunning, | linw (53) | ||
