NOAA becomes the nation's weather, ocean, and climate agency. environment / science ●●

c. 1970 Peer review and science as a self-correcting process 0 cit. Formal peer review, where experts vet a paper before publication, became standard in most journals only in the middle of the twentieth century, later than many assume. It is a filter, not a guarantee of truth, and it misses errors and fraud. The deeper strength of science is that findings must survive repeated testing by others, so it corrects itself over time rather than resting on fixed truths. science / society ●●

April 1971 Salyut 1, the first space station 0 cit. The Soviet Union launches Salyut 1, the first space station, shifting the contest from the Moon to long-duration life in orbit. The USSR would lead in space stations for decades, culminating in Mir. science / technology ●●●

c. 1971 The Bantu problem: where did the expansion begin contested 0 cit. Malcolm Guthrie's four-volume Comparative Bantu mapped shared word-roots across hundreds of Bantu languages and argued the family radiated from a nuclear zone in the Congo woodlands. Greenberg's tree instead pointed to a West African origin. The clash became known as the Bantu problem, and the exact homeland and routes are still argued today. It shows how the same language data can be read toward different histories. science / society ●●●
