I found this to be a fascinating video, saw it pop up on windows live essentials (hey, it IS good for something!) and thought some of what was shown was fascinating.

http://en.wikipedia.org/wiki/Antikythera_mechanism Is probably the most interesting one to me, since it is so old, and you can tell there was considerable skill used to create this device.

http://en.wikipedia.org/wiki/Sailing_stones A very interesting natural phenomena.

http://en.wikipedia.org/wiki/Chase_Vault The chase vault is also rather interesting for those that believe in the paranormal.

I just saw it this morning and thought I would share with you all, get your take on it.

Interesting indeed; I'd not heard of the Chase Vault (and, whilst I don't believe in the paranormal as such, enjoy a good ghost story now and then).

A couple of other mysteries I find interesting are the Voynich manuscript and the loud underwater sounds recorded by the NOAA such as Bloop and Slow Down.

Don't we pretty much know what the Antikythera mechanism was for at this point (and have built a working replica out of Legos)?

I thought that we had more or less conclusively proven in modeled (accurately, no less!) the movement of stars and planets...?

Eclipses, iirc.

From http://en.wikipedia.org/wiki/Antikythera_mechanism :

"The new discoveries confirm that the mechanism is an astronomical analog calculator or orrery used to predict the positions of celestial bodies. This work proposes that the mechanism possessed 37 gears, of which 30 survive, and was used for prediction of the position of the Sun and the Moon. Based on the inscriptions, which mention the stationary points of the planets, the authors speculate that planetary motions may also have been indicated."

Ah, thanks =) The Lego replica I saw was only displaying a countdown to the next eclipse, so I guess there were other components to the mechanism that they didn't replicate.

The unidentified sounds picked up but the NOAA intrigue me. Could they be an as-of-yet undiscovered aquatic mammal?
