In particle physics, the Peccei–Quinn theory is a well-known proposal for the resolution of the strong CP problem.
 It was formulated by Roberto Peccei and Helen Quinn.
 The theory proposes that the QCD Lagrangian be extended with a CP-violating term known as the θ term.
 Because experiments have never measured a value for θ, its value must be small if it exists.

Since the first human spaceflight by the Soviet Union, citizens of 40 countries have flown in space.
 For each nationality, the launch date of the first mission is listed.
 The list is based on the nationality of the person at the time of the launch.
 Only 3 of the 40 "first flyers" have been women (Helen Sharman for the United Kingdom in 1991, Anousheh Ansari for Iran in 2006, and Yi So-yeon for South Korea in 2008).
 Only three nations (Soviet Union/Russia, U.S., China) have launched their own manned spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts.
 Twenty-six "first flights" occurred on Soviet or Russian flights while the United States carried thirteen.

 In addition, the magazine provides a forum through which researchers and the general public can oversee the progress made in fields of study that are associated with the science of astrobiology.
 According to Phys.org, the magazine has a "vast archive of stories covering a broad array of topics ... [and] covers science and nature topics relevant to space, innovation and biology, with an emphasis on the existence, detection and exploration of life in the universe".
 The magazine was created by Helen Matsos, presently Chief Editor and Executive Producer, and began publication in 2000.
