World’s Oldest Computer – Antikythera Mechanism

A paper in a recent issue of the journal Nature (see the Nature News Report) reports an x-ray imaging study of the ~2100 year-old bronze Antikythera Mechanism used as an astronomical calendar.

What is remarkable is not only the fact that this is the oldest/most complex geared mechanism known (over 30 intricate bronze gears) – but that nothing as complex is known to exist for at least another 1000 years.

Also, it is quite interesting that such a sophisticated technology should just vanish. Why didn’t a civilization advanced enough to create such a device continue on, advancing in technology? Why did it just stagnate for 1000 years, and we don’t see another example of such tech until the Middle Ages in Europe?

X-ray imaging of the Antikythera Mechanism:

 

It was found in a shipwreck off the coast of Greece, and is in the National Archaeological Museum in Athens. It had been underwater for over 2000 years, so its condition is remarkable. The artifact is basically priceless, so it wasn’t allowed to leave the museum. So, over 12 tons of x-ray equipment were transported to Athens from the UK to image the device.

Assateague Island

The boys and I went camping at Assateague Island this weekend. Fun time, though I got a bit more sun than I expected. The ponies, while wild, have no fear of people. They visited our campsite both nights (the first night one woke me up when he knocked over one of our food bins). I got out of the tent to find him standing over the bin with an english muffin hanging out of his mouth.

We had toast the next morning.

The campsite was nice, though has no shade (hey, it’s on a beach). Also, no privacy whatsoever. I’m used to camping in the woods where even though you can see/hear a nearby campsite, there are trees between you. And voices do carry at night! You parked the car out of site a bit back, and walked in to the site(s). There was a fence directly behind us (see picture below), to prevent people from walking over the dune to get to the ocean; you walked down about 50 yards to a walkway through the dunes. In the picture below, our tent(s) are directly behind and the ocean is just over the dune.

Birds

The water was *so* warm! First day had gentle waves, but a ton of jellyfish. Didn’t stop Brandon and I from swimming, but Dylan preferred to poke the jellyfish on the beach with a stick vs. swimming with them. The second day there were no (or few) jellyfish, but much bigger waves. No pictures of the ocean because the wind was too intense, and I didn’t want to get sand/spray on my camera. But it was a nice beach. I had bought a cheap beach umbrella the day before – but the wind was a bit intense. At one point the umbrella blew away, and as I was loping after it, Brandon comes running past me to catch it as it was going end-over-end. He just smiled and said something to the effect that it was a good thing he was there or I’d never have caught it. Prolly right, kid.

While the ponies did wake me up both nights, I didn’t mind – especially the 2nd night since they didn’t knock over anything (food was in the car). However, some idiot camper(s) had a dog a few sites over (on the other side of a dune), and it barked a lot during the night, waking me (and others!) at 1, 3 and 5 am. Joy. Why do people take dogs camping if they can’t control them? I used to take my dogs all the time, but kept them under control. Oh well.

The boys slept through the dog and ponies both nights; they had their own tent and were dead to the world until about 6am when I could hear Dylan saying “wakey wakey, Brandon, time to get up”. The older brother was none too happy about that. :)

Maryland Renaissance Festival 2006

Horse
The Maryland Renaissance Festival opened this weekend, and the boys and I spent the day enjoying the festivities. Brandon and Dylan got to participate in the Human Chess Game (Brandon as Black Rook and Dylan as the Red King); they got a kick out of that.

Theistic Evolution


From an essay in “Intelligent Thought”:

theistic evolution – the view that God got the ball rolling with the Big Bang (or even earlier) and has kept his hands off the universe ever since. In this view, evolution occured as part of God’s plan but also according to the laws of physics and biology and without supernatural intervention. Theistic evolution is simply neo-Darwinism with the addendum “God started it.”
