JUST WHEN WE THOUGHT WE WERE EVOLVING MORE BRAINS, a 2000 yr old analog
computer made by the ancient Greeks is documented in a recent Sky and Telescope
article,
http://skytonight.com/news/home/4776976.htmlThe Antikythera Mechanism, was made of brass enclosed in wood, but until
recently, no one has had a close look at it. It turns out this mechanical device
is really an analog computer that "enabled astronomers in the second century BC
to predict the movements of the Moon and Sun, along with lunar and solar
eclipses. It could recreate irregularities in the Moon's motion due to its
elliptical orbit. And it may have even enabled Greek astronomers to forecast the
positions of the known planets." Mike Edmunds of Cardiff University in Wales
says: "This device is just extraordinary, the only thing of its kind. The design
is beautiful. The astronomy is exactly right. The way the mechanics are
designed just makes your jaw drop." All this with a mechanical device instead of
an electronic computer.
Bradley Schaefer of Louisiana State University comments on Antikythera, "This is
all rather exciting, as it shows a greatly more sophisticated technology for the
Greeks than any had really imagined. And this technology is far in advance of
anything else for almost a millennium."
ED.COM. If Schaefer had read the book "Longitude", the true story of English
clockmaker John Harrison, "a lone genius who solved the greatest scientific
problem of his time" in the 1700s, he would realize that "we" have always
had brilliant minds among us. Harrison provided mariners with an accurate method
of determining their longitude at sea, and he did it with the most accurate and
miniature clocks that had ever been constructed. Mariners could use the sun in
the day and the North Star at night (at least in the Northern Hemisphere) to
accurately determine their latitude, but they had no clue about their longitude.
Longitude was important because on frequent occasions ships and even flotillas
would run aground because they didn't know exactly how far they were to the east
and to the west. If Columbus had had one of Harrison's clocks with him 200 years
earlier, he would have known he was going the wrong way to China. Scientists of
Harrison's day were trying to use the appearance and disappearance of the
Galilian moons behind Jupiter, and they disdained intensely Harrison's "stupid"
little machines. Of course, Jupiter could only be seen at night, and only on
cloudless nights, and then only when it was above the horizon at night. Today
mariners avoid running onto rocks by using clocks that are not much more
accurate than those Harrison was crafting 400 years ago. One of Harrison's
wooden clocks, located on the tower of a horse barn in England, is still keeping
accurate time to this day - and because of the "oily" type of wood he used, it
never needs oiling.
The Bible tells us that even further back in the early chapters of Genesis 4,
there were highly skilled and obviously intelligent craftsmen. "We" haven't
gotten smarter - we just have to use different technology. Most of the old
knowledge and skills have been lost - I doubt if anyone could construct an
Antikythera computer today, or a wooden clock that can keep accurate time for
centuries - or a huge seagoing wooden ship the size of Noah's ark, that
worked with no sea trials and no life boats.
