The technique was reputed to have been in use in China around the same time but no artifacts remain. In 1915 Nikola Tesla, in an essay entitled "The Fairy Tale of Electricity" promoting the appreciation of electrical developments, proposed what seemed a plausible explanation for some of the magical powers of the Ark.

Similarly he calculated the distance to ships at sea by noting the azimuth angle of the ship from a baseline of two widely spaced observation points a known distance apart on the shore and scaling up the distance to the ship from the dimensions of a smaller similar triangle.

In this way he was able to calculate the distance to far off objects without measuring the distance directly, the basis of modern surveying.

It seems Tesla's explanation was appropriately named. Also called magnetite, lodestone is a magnetic oxide of iron (Fe) which was mined in the province of Magnesia in Thessaly from where the magnet gets its name.

Lodestone was also known in China at that time where it was known as "love stone" and is in fact quite common throughout the world.

Thales also demonstrated the effect of static electricity by picking up small items with an amber rod made of fossilised resin which had been rubbed with a cloth. C.) an Ionian Greek, is considered by many to be the Father of Mathematics.

He also noted that iron was attracted to lodestone. Like Thales, he had travelled to Egypt and Babylon where he studied astronomy and geometry. "In a right-angled triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides" is well known to every schoolchild.

Hieroglyphic script evolved slightly later in Egypt. found in a temple at Erech in Mesopotamia show a chariot with solid wooden wheels.

Though the script appeared on vases and stone carvings, many important Egyptian historical scripts and records were written in ink, made from carbon black (soot) or red ochre mixed with gelatin and gum, applied with a reed pen onto papyrus. Evidence from Ur indicates that the simpler potter's wheel probably predates the use of the axled wheel for transport because of the difficulty in designing a reliable mechanism for mounting the rotating wheel on a fixed hub or a rotating axle on the fixed load carrying platform.

Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

"Either you do the work or you get the credit" Yakov Zel'dovich - Russian Astrophysicist Fortunately it is not always true.

Surprisingly although they were aware of its magnetic properties, neither the Greeks nor the Romans seem to have discovered its directive property. D., the somewhat unscientific Roman chronicler of science Pliny the Elder, completed his celebrated series of books entitled "Natural History". The Greek philosopher and scientist, Thales of Miletus (624-546 B.
