Equipped with only a stick, he did not even need to leave Alexandria to make this remarkable breakthrough. It came off easily enough and clanged down into the pit. The importance of such an unusual electrical phenomenon seems to have gone completely unrecorded within the Parthian and contemporary cultures and then to have been completely forgotten despite extensive historical records from the period.

We can think this thing through for a while, but sooner or later I'm going to have to take a stab at turning one of those nuts. The metal from which barrels are made is soft and liable to corrosion and marking and scratching whereas most of the rest of the metalwork is hardened and more protected, so barrels are almost always in the worst condition of any part of the gun and can really drag down the appearance, so its understandable that they get re-browned.

The thing you want for your engines are the most volatile fractions, the liquids that boil off first, like gasoline and benzene.

These were carried to a long table where the coded information was copied off onto slates. Water began to run down into the pit and Mikah went to work bailing it out, while the gap between the hood and the baseplate widened.

The asphalt completely covers the copper cylinder, electrically insulating it so that no current could be drawn without modifying the design and no wires, conductors, or any other sort of electrical equipment associated with the artifacts have been found.

Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems.


It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools.[1]. Barrel with RH hand plug removed and LH plug started – it was held vertically in the vice to get this far.

The long wrench is shown – larger cutouts fit single barrelled breech plugs – the barrels are still joined although it looks as if they are apart.
