Can you solve the prisoner hat riddle? - Alex Gendler The ‘prisoners and hats puzzle’ is a classic logic problem with many variants, some of which are described and summarized here. Like other puzzles where each player has information about the other players but not about themselves, they rely on inductive logic and the hierarchy of beliefs to figure out the other players’ thought processes to deduce the missing information. Just remember – if you try to stump other people with this kind of puzzle, make sure you have the right answer yourself.
Old trees reveal Late Antique Little Ice Age (LALIA) around 1,500 years ago WSL dendroclimatologist Ulf Büntgen and his fellow researchers were able for the first time to precisely reconstruct the summer temperatures in central Asia for the past 2,000 years. This was made possible by new tree-ring measurements from the Altai mountains in Russia. The results complement the climatological history of the European Alps, stretching back 2,500 years, that Büntgen and collaborators published in 2011 in the journal Science.

Race May Be a Social Construct, But Racism is Very Real “Race is a social construct.” I saw this sentence on the projector in my Race and Ethnic Relations class and jotted it into my notebook. Figuring that the statement was simply being used as an indication of how ridiculous and harmful racism is, I was on board with it. I even used it in conversation a couple times. During a discussion in another course, a fellow student of color mockingly repeated the phrase, “Race is a social construct.” At first, I had to wonder why this phrase was worthy of mockery.

Rethinking the Social Structure of Ancient Eurasian Nomads: Current Anthropology Research : Nature First Posted: Feb 24, 2012 02:49 PM EST Rethinking the social structure of ancient Eurasian nomads: Current Anthropology research (Photo : Flickr.com/Lyalka) Prehistoric Eurasian nomads are commonly perceived as horse riding bandits who utilized their mobility and military skill to antagonize ancient civilizations such as the Chinese, Persians, and Greeks. Although some historical accounts may support this view, a new article by Dr. Michael Frachetti (Washington University, St. Louis) illustrates a considerably different image of prehistoric pastoralist societies and their impact on world civilizations more than 5000 years ago.

The real question about the Mongols is, “Why did they win, and why did they win so big?” The Mongol empire is the great singularity in human history (though I’m sure that there are others in human prehistory): how did two or three million nomads — a nation without cities or writing — manage to conquer over half of Eurasia in less than a century? Invasions and raids on wealthy states by their poorer neighbors are a historical constant, but nobody asks “Why the Petchenegs?” or “Why the Xianbei?”, or “Why the Sarmatians?”.
Using Primary Sources - Teachers Primary sources are the raw materials of history — original documents and objects which were created at the time under study. They are different from secondary sources, accounts or interpretations of events created by someone without firsthand experience. Examining primary sources gives students a powerful sense of history and the complexity of the past. Helping students analyze primary sources can also guide them toward higher-order thinking and better critical thinking and analysis skills.
