Problem: House music:

Towards the end of the 1990s and into the 2000s, producers such as Daft Punk, Stardust, Cassius, St. Germain and DJ Falcon began producing a new sound out of Paris's house scene. Together, they laid the groundwork for what would be known as the French house movement. By combining the harder-edged-yet-soulful philosophy of Chicago house with the melodies of obscure funk, state-of-the-art production techniques and the sound of analog synthesizers, they began to create the standards that would shape all house music.

When did Daft Punk begin producing a new sound?

A: end of the 1990s and into the 2000s

Problem: Friedrich Hayek:

Some socialists such as H. D. Dickinson and Oskar Lange, responded by invoking general equilibrium theory, which they argued disproved Mises's thesis. They noted that the difference between a planned and a free market system lay in who was responsible for solving the equations. They argued, if some of the prices chosen by socialist managers were wrong, gluts or shortages would appear, signalling them to adjust the prices up or down, just as in a free market. Through such a trial and error, a socialist economy could mimic the efficiency of a free market system, while avoiding its many problems.

What type of economic system did the socialists want to avoid?
---
A: free market

Problem: Communications in Somalia:

A: unanswerable

Problem: Richard Feynman:

Feynman devoted the latter half of his book What Do You Care What Other People Think? to his experience on the Rogers Commission, straying from his usual convention of brief, light-hearted anecdotes to deliver an extended and sober narrative. Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. For instance, NASA managers claimed that there was a 1 in 100,000 chance of a catastrophic failure aboard the shuttle, but Feynman discovered that NASA's own engineers estimated the chance of a catastrophe at closer to 1 in 200. He concluded that the space shuttle reliability estimate by NASA management was fantastically unrealistic, and he was particularly angered that NASA used these figures to recruit Christa McAuliffe into the Teacher-in-Space program. He warned in his appendix to the commission's report (which was included only after he threatened not to sign the report), "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled."

Who did NASA recruit while using accurate safety numbers?
