Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.

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.

Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.

They did not have the benefit of cheap, off the shelf, mass produced batteries. In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells. Today the cells are components in battery systems, incorporating electronics and software, power management and control systems, monitoring and protection circuits, communications interfaces and thermal management.

At the end of the fourth millennium B. Bronze is a relatively hard alloy of copper and tin, better suited for the purpose than the much softer copper enabling improved durability of the weapons and the ability to hold a cutting edge. The use of bronze for tools and weapons gradually spread to the rest of the World until it was eventually superceded by the much harder iron.

Mesopotamia, incorporating Sumer, Babylonia and Assyria, known in the West as the Cradle of Civilisation was located between the Tigris and Euphrates rivers The name means "land between the rivers" in the so called Fertile Crescent stretching from the current Gulf of Iran up to modern day Turkey.

See Map of Mesopotamia Unfortunately this accolade ignores the contributions of the Chinese people and the Harappans of the Indus Valley, Modern day Pakistan who were equally "civilised" during this period practicing metallurgy copper, bronze, lead, and tin and urban planning, with civic buildings, baked brick houses, and water supply and drainage systems.

From around B. Called Cuneiform Writing from the Latin "cuneus", meaning "wedge", it was developed as a vehicle for commercial accounting transactions and record keeping. 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 clay subsequently hardened in the Sun or was baked to form permanent tablets. Hieroglyphic script evolved slightly later in Egypt. 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.greek mathematics - pythagoras Pythagoras of Samos (c BCE) It is sometimes claimed that we owe pure mathematics to Pythagoras, and he is often called the first "true" mathematician.

Sep 21,  · A thin sliver of Moon, where the illuminated portion appears to coincide with the same portion of a sphere that could be lit up by the Sun..

If you were both curious and . Viewpoint: No, later scientists such as Nicolaus Copernicus and Galileo correctly realized that Earth moves around the Sun, not vice versa, and thus cannot be the center of the universe. It is easy in our human nature to believe that we are the center of the universe.

A newborn infant must learn through experimentation and sensation that he is a part of the world, not the entirety. Pythagoras of Samos (c. – c. BC) was an Ionian Greek philosopher and the eponymous founder of the Pythagoreanism movement.

His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, Western philosophy.
