Physicist Marietta Blau was born #OTD in 1894. She pioneered the use of nuclear emulsion plates for particle detection, and discovered "disintegration stars" produced by cosmic rays interacting with nuclei

My 8yo has discovered Google Docs, and now instead of playing video games she is obsessed with word-processing and experimenting with different templates and making things like a resumé for

Physicist Lise Meitner was born #OTD in 1878. She discovered fission in uranium and was the first person to understand both its mechanics and implications.Image: Atomic Heritage Foundation (photographer unknown)

The mathematician Karl Weierstrass was born #OTD, Halloween, in 1815. The fools at the academy all said he was mad, but in 1872 he announced that he had succeeded in

Brit Hume is linking to a post by a radically anti-science fringe group known for pushing bizarre claims that are not supported by (and often completely contradicted by) evidence. Naturally

It's halfway through Wednesday and you're all doing great. Let's share some Hubble images. Here's the Bubble Nebula (NGC 7635) in Cassiopeia.Image: Hubble/ESA Former spiral galaxies NGC 4038 and NGC

Mathematician Katherine Johnson, whose orbital mechanics calculations played a vital role in so many NASA missions, was born #OTD in 1918. John Glenn trusted her calculations more than his onboard

Somehow I’ve lucked out and have an 8yo who thinks secretly reading under the covers past her bedtime is an act of rebellion, and it hasn’t yet occurred to her

Physicist and astronomer Georges Lemaître was born #OTD in 1894. In 1927 he proposed a model of an expanding Universe. Then, in 1931, he ran the clock backwards and hypothesized

Let me tell you a short story about how much a physicist can learn using dimensional analysis and a few pictures of an atom bomb detonation.https://twitter.com/mcnees/status/1283765045395173379 During WWII a British

The physicist Maria Goeppert Mayer was born #OTD in 1906. She developed the nuclear shell model of the nucleus, for which she was awarded the 1963 Nobel Prize in Physics.Image:

The astronomer Heber Curtis was born #OTD in 1872. In his “Great Debate” with Harlow Shapley, he famously argued that each of the countless spiral nebulae observed by his colleagues
