Glassmakers took a step forward in advancing the process when lead crystal glass was created as an answer to the clouding that naturally occurred.

Lincoln's first education was from his mother, Nancy Todd Lincoln, who taught him how to read and do math without the benefit of books. He continued this home-educated tradition for most of his life. Lincoln "thinks that the aggregate of all his schooling did not amount to one year," he said in a biography published in an 1860 edition of the Chicago Tribune. He made up for his lack of formal schooling by voracious reading and writing, teaching himself both Latin and the law.

How did Maine get its name?

In 1622, King Charles of England granted a charter over what later became known as Maine to Sir Ferdinando Gorges and Captain John Mason. During his time in the royal navy, Mason served in the Orkney Islands, whose chief island is called Mainland. Historians suspect this served as inspiration for the state's eventual name.\nFirst, however, Mason gave the province the names of New Hampshire, Laconia and New Somerset. The last one was particularly disliked by King Charles, so Mason finally wrote in the 1639 charter that the colony would thereafter be known as "Mayne." The name was fixed in ..

How did the Allies win World War I?

By 1917, three years after World War I began, the Allies, made up of Britain, France and Russia, were losing. Outmanned and outmaneuvered, Britain reached out to the United States, which had remained neutral. The United States joined the war after a German U-boat sunk the British ocean liner RMS Lusitania, killing 159 Americans, and after Germany attempted to persuade Mexico to join the war against the United States.

How was copper discovered?

Part of the reason that archaeologists do not know who discovered copper first or where the discovery was made is that copper is such a ubiquitous metal. Copper is found in large reserves throughout the Earth. Modern humans mine copper in the United States, China, Zambia, Zaire, Canada and Peru. Copper is usually mined from the ground as an ore or an impure mineral. It must then be purified and smelted so that it can be used to make objects. Israel, Jordan and Egypt have the oldest copper smelting sites ever discovered. These smelting facilities were likely active around 4500 B.C.\nCopper has ..
