Carbon dating science

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 calendar adopted by the Sumerians, Babylonians and Assyrians was based 12 lunar months and seven-day weeks with 24-hour days.

The Mesopotamians thus introduced the 60-minute hour, the 60-second minute and the 360-degree circle with each angular degree consisting of 60 seconds.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.As an undergraduate physic major I got to do an experiment using both liquid nitrogen and liquid helium. refers to in this video.) It's neat to see the inside of a liquefaction plant, and also to learn that systems are in place to recycle helium from MRI machines.Volta's pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.The clay subsequently hardened in the Sun or was baked to form permanent tablets. For the first time news and ideas could be carried to distant places without having to rely on a messenger's memory and integrity.Hieroglyphic script evolved slightly later in Egypt. found in a temple at Erech in Mesopotamia show a chariot with solid wooden wheels.Graphene is a relatively new and promising material, displaying a unique array of physical and chemical properties.Although considered to be especially promising for the use in energy storage applications, graphene has only recently been implemented as an electron conducting additive for lithium ion battery cathode materials.
