The metal that could only be made in large quantities when electricity became widely available was once valued more than gold. Eight per cent of the Earth's crust is made up of mineral aluminium such as potassium aluminium sulfate. This was used in times past for fire-proofing and tanning of leather. Today, it is in baking powder and aftershave. The refinement into aluminum metal wasn't theorized until the late 19th century. Hans christian Oersted created the first sample of the metal in 1825. It was highly contaminated. Sodium was then used by Henri Saint-Claire Deville to produce more. In 1845 scientists found it to be extremely light in weight. By 1855 small ingots were made and its price skyrocketed. Indeed, Napoleon 111 valued his aluminium cutlery more the the gold alternative. Electrolysis was the major breakthrough in the production of large quantities of aluminium. Bauxite was identified as the best and plentiful source material. The price fell 80...

Minerals are classified into species like animals. You would think that all minerals had been identified by scientists. This is not the case. A completely new mineral has been found in Australia at Polar Bear peninsula, Southern Lake Cowan. It is named after the two scientists who discovered it, Christine and Andrew Putnis based at the University of Münster in Germany. Putnisite is now among the 4,000 known minerals. It was found on the surface of Lake Cowan in Western Australia. The mineral is composed of tiny 0.5 mm diameter crystals in volcanic rock. Its crystals are square and in a range of colors: white, pink, purple and dark green. The mineral is composed of oxygen, hydrogen, carbon, sulphur, calcium, strontium and chromium. It glistens as light can penetrate the substance. Unlike other minerals which belong to families similar in structure, putnisite is unique. Nature joins things together to form minerals. Scientist did not believe a blend of these bases cou...

Everyone knows that Australia is old. Just how old has been defined by science - A zircon crystal on a Western Australian sheep station is the oldest piece of planet Earth. It is 4.4 billion years old. Tests were done to determine the crystal's age. The rate of decay of uranium against the constant lead showed how old it was. This was confirmed by atom-probe tomography where the mass of lead atoms is measured. The zircon particle was created on the Earth's crust soon after the planet formed. And the Earth was not a violent place until much later. Water was already present and there is a high probability that life began at this time. The Hadean eon as this period is called in now a misnomer because it means Hadean the god of hell. Proof of life is unlikely. Science is not advanced enough yet to fully examine this period. Very little can be identified as originating in this period of the Earth's development. Science by Ty Buchanan http://www.adve...
