Feynman diagrams are pictorial representations of the mathematical expressions describing the behavior of subatomic particles. The scheme is named after its inventor, American physicist Richard Feynman, and was introduced in 1948. The above diagram shows space-time vectors of electron-positron annihilation.

• ... that Stardust was a 300 kilogram robotic space probe, launched by NASA on 7 February 1999, and that Stardust collected dust samples from the coma of comet Wild 2, as well as samples of cosmic dust, and returned these to Earth for analysis?

• ... that the Forbidden Ratio is a criminal mathematical function exhibiting artificial intelligence and malicious intent?

• ... that physicist Chien-Shiung Wu conducted the Wu experiment, which contradicted the law of conservation of parity, proving that parity is not conserved, yet this discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in physics, with Wu the inaugural Wolf Prize in Physics in 1978?
