The Schmidt Sting Pain Index is a scale that rates the relative pain caused by the stings of nearly 80 species of insects in the Hymenoptera order, which includes wasps, bees, and ants. It is mainly the work of entomologist Justin O. Schmidt, who spent years subjecting himself to the stings, ranking them, and describing some of the experiences in colorful detail. Which insect's sting was described as producing "trembling in the form of a totally uncontrollable urge to shake the affected part"? Discuss
More than 100 people were killed and thousands more left injured or homeless when a dam in West Virginia's rural Buffalo Creek Valley gave way. It had been built out of sediment left over from coal mining and collapsed after a heavy rainfall, sweeping away two more dams in its path. The collapse unleashed approximately 130 million gallons of black waste water onto the residents of the valley below. A study done 17 years later found that residents still suffered what lasting psychological effect? Discuss
Cruelty was the devil's own trade-mark, and if we saw any one who took pleasure in cruelty we might know who he belonged to ... On the other hand, where we saw people who loved their neighbors, and were kind to man and beast, we might know that was God's mark. Discuss
After Iraqi President Saddam Hussein's troops invaded Kuwait on August 2, 1990, several countries in the United Nations formed a military coalition—including troops and equipment from the U.S., France, and Britain—to force them out. Operation Desert Storm began on January 17, 1991, and, for five weeks, U.S. and British air forces relentlessly bombed Baghdad. This was followed by four days of a ground war, which resulted in Hussein's troops leaving Kuwait. February 26 is a national holiday in Kuwait celebrating the end of Iraq's military presence in Kuwait. Discuss

The day is marked with ceremonies at the site of the revolution in Quezon City, a part of Manila. Discuss
What began as a practical joke became a famous, decades-long scientific hoax when a prominent geologist not only fell for it, but vigorously defended it as real. After miners in Calaveras County, California, claimed to have found a human skull deep within a mine, Harvard University Professor Josiah Whitney—then the State Geologist of California—announced that it was the earliest evidence of humans on the continent. Where might the miners who planted the skull have obtained it in the first place? Discuss
One of the first prominent female chemists in Germany, Noddack was nominated several times for a Nobel Prize but never won.

She also participated in the discovery of another element, which her team named masurium, but they could not prove its existence. It was finally isolated by others in 1937 and named what? Discuss

It wasn't until the ninth century that the Lenten season, called the Great Lent in the East to differentiate it from the Advent fast called Little Lent, was fixed at 40 days (with Sundays omitted). For centuries the Lenten season has been observed with certain periods of strict fasting, as well as giving up something—a favorite food or other worldly pleasure—for the 40 days of Lent. Celebrations such as Carnival and Mardi Gras offered Christians their last opportunities to indulge before the rigorous Lenten restrictions. Discuss

How many people faced criminal charges in the aftermath of the tragedy? Discuss
