The lexical compilations known as dictionaries have taken many forms throughout the ages. The earliest dictionaries were created by the Greeks in the first century CE, while multilingual dictionaries emerged during the Middle Ages. Though today’s lexica contain alphabetized word lists, until the 18th century, English dictionaries were predominantly organized by topic. What were some of the distinctly American words that Noah Webster first documented in his 1828 dictionary? Discuss

Abbas the Great
Shah Abbas I ascended the Persian throne in the late 16th century, after participating in the coup that deposed his father. Persian artistic achievement flourished during Abbas’s reign. The empire’s new capital, Isfahan, was transformed into one of the world’s most beautiful cities and quickly became one of the most important cultural centers in the Islamic world. Abbas’s rule was tarnished, however, by his cruelty to his family. What did he do to three of his sons? Discuss
The Klondike Gold Rush
In August 1896, a party led by Skookum Jim Mason discovered rich gold deposits near the confluence of the Klondike and Yukon rivers in northwest Canada. The news quickly spread to other mining camps in the river valley and reached the US within a year, setting off the Klondike Gold Rush that drew more than 30,000 prospectors to the area. By the time mining ended in 1966, the area had yielded $250 million in gold. What famous American author took part in the gold rush? Discuss
Mirror Neurons
The discovery of mirror neurons in primates is considered by some to be one of the most important findings in neuroscience in the last decade. These neurons, which are also believed to exist in humans, act as a “mirror” for behavior, firing both when an animal performs an action and when it observes another carrying out that action. This system may play a role in learning new skills and understanding the behavior of others. What human brain disorder may be linked to a mirror neuron deficiency? Discuss
The Conscription Crisis of 1917
The Conscription Crisis of 1917 was a political and military crisis in Canada during WWI that was precipitated by the military’s failure to create units for French-speaking forces. Instead the French-Canadian volunteers were assigned to various English-speaking units. Witnessing what they perceived as the mistreatment of the first contingent, many French-Canadians elected not to volunteer, leading legislators to pass a conscription act. What was the political aftermath of this crisis in Quebec? Discuss
Graphology
Used to evaluate job recruits, potential jurors, and romantic partners, graphology is the study and analysis of handwriting, especially in relation to human psychology. Supporters cite anecdotal evidence for its accuracy in personality evaluation, but empirical studies have often failed to prove its validity. Among its most controversial forms, medical graphology uses handwriting analysis to evaluate patient health. What do proponents of holistic graphology claim John Wayne’s signature revealed? Discuss
Along the River During the Qingming Festival
Often called “China’s Mona Lisa,” Along the River During the Qingming Festival is a 17-ft (5.2-m) long panoramic painting that depicts life during the Song dynasty. The subject of several similar works painted over the next few hundred years, the 12th-century original depicts 814 people in a bucolic countryside and busy city and reveals some of the nuances of class structure at the time. Why do some scholars question the traditionally accepted translation of the painting’s name? Discuss
Absolute Zero
The lowest temperature theoretically achievable by a system, absolute zero is the point at which substances possess no thermal energy. In 1848, British physicist Lord Kelvin devised a temperature scale that set absolute zero, or 0°K, at -273.15°C. Although absolute zero is impossible to achieve, scientists have brought some substances within a billionth of a degree of 0°K, inducing in these materials odd quantum effects such as superconductivity. Where is the coldest known place in the universe? Discuss
The Hussite Wars
Arguably the first European wars in which hand-held gunpowder weapons played a decisive role, the Hussite Wars were a series of 15th-century conflicts that followed the execution of Czech religious reformer Jan Hus by the Roman Catholic Church. Protests from his followers, called Hussites, who opposed the ascension of Emperor Sigismund to the Bohemian throne, led to three anti-Hussite crusades and a number of armed conflicts. War broke out after what was thrown out of windows in Prague? Discuss
Stari Most
Stari Most, meaning “The Old Bridge,” is a 16th-century bridge in Bosnia and Herzegovina that is believed to have been the largest single-span arch bridge in the world when it was built. Charged under pain of death to construct a bridge of such unprecedented dimensions, the architect that built it reportedly prepared for his own funeral on the day the scaffolding was finally removed. It is now a UNESCO World Heritage Site. For what dangerous tradition do the people of Mostar use the bridge? Discuss
