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.
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.
He was the world's first named architect and administrator who around 2725 B. built the first pyramid ever constructed, the Stepped Pyramid of Saqqara. The first outlines surgical treatments for various wounds and diseases and the second contains 877 prescriptions and recipes for treating a variety of medical conditions making Imhotep the world's first recorded physician. The earliest evidence of the art of stencilling used by the Egyptians. in the fine linen, with cunning work." The Egyptians also made coarse glass fibres as early as 1600 B. and fibers survive as decorations on Egyptian pottery dating back to 1375 B. It was basically a wooden box of acacia wood lined with gold and also overlaid on the outside with gold.
Papyri were unearthed in the nineteenth century dating from around 1600 B. Other contemporary papyri described Egyptian mathematics. Egyptian teachings provided the foundation of Greek science and although Imhotep's teachings were known to the Greeks, 2200 years after his death, they assigned the honour of Father of Medicine to Hippocrates. Designs were cut into a sheet of papyrus and pigments were applied through the apertures with a brush. The Xia dynasty in China perfected the casting of bronze for the production of weapons and ritual wine and food vessels, reaching new heights during the Shang dynasty (1600-1050 B. The lid was decorated with two "cherubim" with outstretched wings.
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.
The writing was in the form of a series of wedge-shaped signs pressed into soft clay by means of a reed stylus to create simple pictures, or pictograms, each representing an object. the script progressively evolved to encompass more abstract concepts as well as phonetic functions (representing sounds, just like the modern Western alphabet) enabling the recording of messages and ideas.Recent calculations have shown however that the capacitance of the box would be in the order of 200 pico farads and such a capacitor would need to be charged to 100,000 volts to store even 1 joule of electrical energy, not nearly enough to cause electrocution. The magnetic properties of the naturally occurring lodestone were first mentioned in Greek texts.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.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.
Produced from the freshwater papyrus reed, the papyrus scrolls were fragile and susceptible to decay from both moisture and excessive dryness and many of them have thus been lost, whereas the older, more durable clay cuneiform tablets from Mesopotamia have survived. Sumerian mathematics and science used a base 60 sexagesimal numeral system.
There are also claims that the Archimedes' Screw may have been invented in Mesopotamia and used for the water systems at the Hanging Gardens of Babylon. Fine metal working techniques were also developed in Egypt where filigree jewellery and cloisonné work found in Tutankhamun's tomb dating from 1327 B. was made from delicate wires which had been drawn through dies and then soldered in place. Fine wire also made by the Egyptians by beating gold sheet and cutting it into strips. Around this date, after his escape from Egypt, Moses ordered the construction of the Ark of the Covenant to house the tablets of stone on which were written the original "Ten Commandments".
