List of time periods The categorization of time into discrete named blocks is called periodization. This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (concerning the various time periods in the origin and evolution of our universe), geological (concerning time periods in the origin and evolution of earth ) and historical (concerning time periods in the origin and evolution of mankind). Human time periods These can be divided broadly into prehistorical (before history began to be recorded) and historical periods (when written records began to be kept). Prehistorical periods In archaeology and anthropology, human prehistory is subdivided around the three-age system. The dates for each age can vary by region. Historical periods Full article ▸
A History of the World - Location - Europe MacroHistory : World History This Isn't the Speech I Expected to Give Today This isn't the speech I expected to give today. I intended something else. For the last several years I've been taking every possible opportunity to talk about the soul of democracy. 'Something is deeply wrong with politics today,' I told anyone who would listen. And I wasn't referring to the partisan mudslinging, or the negative TV ads, the excessive polling or the empty campaigns. This wasn't something I came to casually, by the way. But I'm not the same man I was six weeks ago. For this generation, that moment will be September 11th, 2001-the worst act of terrorism in our nation's history. This is their real target, to turn our imaginations into Afghanistans, where they can rule by fear. This summer our daughter and son-in-law adopted a baby boy. None of us is spared. Returning from Washington on the train last week, I looked up and for the first time in days saw a plane in the sky. I wish I could find the wisdom in this. But I haven't been ready for reflection. He's right.
History Egypt, land of the pyramids, mighty monuments constructed in the early days of history. Monuments that endure to this day attracting visitors across the world. Many visitors come to Egypt to see one pyramid in particular, the Great Pyramid of Cheops at Giza, one of the Seven Wonders of the World, the most celebrated man-made constructions of all time. Of the seven, only the Great Pyramid of Cheops survives, but history and archaeology are able to tell us the stories of all seven, including the Hanging Gardens of Babylon, the Statue of Zeus at Olympia, the Temple of Artemis at Ephesus, the Mausoleum at Halicarnassus, the Colossus of Rhodes, and the Pharos of Alexandria. And for the first time in some 3,000 years, viewers see the Seven Wonders restored to their original glory. Twit This!
Elizabeth I: An Overview (BBC) Stone Age Timelines Human prehistory and the Stone Age… a timeline critique (4th edition - October 2012) by A.O. Kime for information on 'renting' this article, see Rent-a-Article In the 1820’s, in order to address the prehistory of mankind more clearly, it was thought necessary to divide it into time periods, thus a ‘three-age’ system of the (1) Stone Age, (2) Bronze Age and (3) Iron Age was adopted. While this system is still more-or-less in common use today, refinements were inevitable and the Stone Age, so immensely long, was later subdivided into three major periods as follows: Paleolithic (c 2,000,000 – c 10,000 B.C.) The Paleolithic time period is by far the longest, beginning some (circa) two million years ago to coincide with the first evidence of toolmaking and ending around 10,000 B.C. to coincide with the end of the last ice age (Pleistocene epoch). • Lower Paleolithic (two million – 100,000 B.C Mesolithic (c 10,000 – c 5,500 B.C.) Neolithic (c 5,500 – c 2,500 B.C.) Stone Age observations A.O.
