Max Delbrück, born #OTD in 1906, was a major force in the origins of molecular biology. Having trained in quantum physics, he saw phage as the “atom” of biology.
Although he had died years before, his ethos of intellectual rigor was still palpable a Caltech when I was there and his former office was a hangout as the Delbrück lounge.

The Voyager 1 space probe was launched from Cape Canaveral #OTD in 1977, a few weeks after Voyager 2.

Now it's the most distant human-made object – about 14.96 billion miles from Earth, racing away from us at 38,000 miles per hour with respect to the Sun.

Geneticist Liane Russell was born #OTD in 1923.

She pioneered the study of mutagenesis and teratogenesis due to radiation, and identified the role of the Y chromosome in sex determination. Her work led to diagnostic x-ray safety standards for women of childbearing age.

Science, the joy of wild places, and civic engagement as a response to fascism – this is one of my favorite threads.
