Topic: Worlds most modern ancient advancement Posted: 29-Sep-2004 at 19:06 |
Everyone knows that ancient civs have been said to have invented things
that we are only getting a grasp on in the last hundred years. What is your
opinion on this.

The colloseum was said to have a retractable roof which we have only started to get a hold of in the last 30 years or so.

I think a greek in Alexandria made a toy 'train' one time, but he never recognized the significance of it.

I heard that sumerians had helmets that were so fine that it could be rivaled only by our current technology.

How about the way sound carries in Greek Amphitheaters? No one
knows how they did it, no one can design a theater which carries sound
as well either.
And Greek Fire, I'm pretty sure that we don't know its chemical composition today.

Tripitaka Koreana, consisting of over 80,000 blocks, created during mongol invasions, was stored in Hae-In temple, but in the 1970's they moved some to a modern storage facility with air humidity control etc, and defections started to appear, and they moved them back to the old temple where no problems arose

Is that girl irresistible or is it just.
As for invention, I'll say french kiss.

I was looking for that
I believe i saw a doc - on a mechanical moon calandar - from around the Galileo era. Galileo also created a pretty kool - measuring device - for the "mile stones"

I think we're just beginning to grasp what Greek Fire was. It was never written down, so we just may never know. But it's believed to be some kind of petroleum product.

In June, 1936, while a new railway was being constructed near the city of Baghdad workers uncovered an ancient tomb. In the excavation that followed it was determined that the tomb was built during the Parthian period which ranged from 250 BC to AD 250 (+/-).
According to most texts the "voltic pile," or electric battery, was invented in 1800 by the Count Alassandro Volta. Volta had observed that when two dissimilar metal probes were placed against frog tissue, a weak electric current was generated. Volta discovered he could reproduce this current outside of living tissue by placing the metals in certain chemical solutions. For this, and his other work with electricity, we commemorate his name in the measurement of electric potential called the volt. The little Parthian jar found in ancient Western Iranian territories of Greater Iran (now Iraq), suggests that Volta didn't invent the battery, but reinvented it. The jar was first described by German archaeologist Wilhelm Konig in 1938. The jar was found in Khujut Rabu just outside modern Baghdad and is composed of a clay jar with a stopper made of asphalt. Sticking through the asphalt is an iron rod surrounded by a copper cylinder. When filled with vinegar - orany other electrolytic solution - the jar produces about 1.5 to 2.0 volts.
The jars are believed to be about 2000 years old from the Parthian period (The third Iranian dynasty ruled roughly 248 BCE to 28 April CE 224), and consist of an earthenware shell, with a stopper composed of asphalt. Sticking through the top of the stopper is an iron rod. Inside the jar the rod is surrounded by a cylinder of copper. Konig thought these things looked like electric batteries and published a paper on the subject in 1940. World War II prevented immediate follow-up on the jars, but after hostilities ceased, an American, Willard F. M. Gray of the General Electric High Voltage Laboratory in Pittsfield, Massachusetts, built some reproductions. When filled with an electrolyte like grape juice, the devices produced about two volts.
Not all scientists accept the "electric battery" description for the jars. If they were batteries, though, who made them and what were they used for? Unfortunately, there is no written record as to the exact function of the jar, due to destruction of Iranian literary sources and libraries by Arabs upon invasion of Iranian territories in 7th century, but the best guess is that it was a type of battery. Scientists believe the batteries (if that is their correct function) were used to electroplate items such as putting a layer of one metal (gold) onto the surface of another (silver), a method still practiced in Greater Iran today.

Electroplating is practiced everywhere around the world not just in iran. I find this hard to believe, that they've discovered a battery so early. If they've invented that, this would have been a great achievement. So the arabs were a killer of great civilisation, if this invention was recorded and someone has exploited them today we would been travelling outside the solar system.

Don't be so doubtful...
The only thing that bothers me is the purpose of them. Sure,
elctroplating. But surely there must be some other purpose
too? And perhaps the invention didn't spread because it didn't
really have that much use back then?

Rather trying to find out how the old Greeks built their triremes, which is a completely different matter (archaeology/reverse engineering as opposed to actual invention/engineering).
