You may recall that back in November 2021 we received word that Maynooth University had been awarded one of ten new senior professorial positions under the Strategic Academic Leadership Initiative (SALI). I blogged about this scheme here. The position we were awarded is a Chair (Full Professorship) in Observational Astrophysics or Cosmology. We haven't been able to make an appointment so far, despite trying!

Google Garbage
In the course of double-checking the time of perihelion for yesterday's post I did a quick Google search. What came up first was this: Google search results nowadays are prefaced by a short summary like this one, presumably generated by some sort of AI. This one - like many others I've seen recently - is just plain wrong. The time of perihelion was 13.28 Universal Time, not 09.00.

Happy #QuantumDay to all who celebrate! Max Planck submitted work on blackbody radiation to the German Physical Society #OTD in 1900. His novel “quantum hypothesis” suggested that matter emits and absorbs light with frequency f only in discrete chunks of energy E=hf. 🧪 ⚛️ (1/n) Image: AIP

35 years ago today a gunman walked into an engineering classroom at the École Polytechnique in Montreal, separated the women from the men and killed 14 of them. It was the ultimate manifestation of the gender-based bias and violence we still face in STEM today. We must never forget. 👩🏻‍🔬 🧪
Photos of the 14 victims of the Montreal massacre:

Geneviève Bergeron, Hélène Colgan, Nathalie Croteau, Barbara Daigneault, Anne-Marie Edward, Maud Haviernick, Barbara Klucznik-Widajewicz, Maryse Laganière, Maryse Leclair, Anne-Marie Lemay, Sonia Pelletier, Michèle Richard, Annie St-Arneault and Annie Turcotte.

Did you know that scientists no longer use the Richter Scale to measure earthquake magnitude? Now, we tend to use the “Moment Magnitude (Mw)” scale, which was built off of the tenets of the Richter scale. 🧪 ⚒️

BIG NEWS my friends!! I'm so excited to announce that I’ve been selected as a top winner of the National Academies Eric and Wendy Schmidt Awards for Excellence in Science Communications given by National Academies in partnership with Schmidt sciences! #scicomm 🧪
Sanjana Curtis makes complex astrophysics concepts accessible and interesting through both her writing and video creation. Her ability to connect art and astrophysics, explain the cosmic origins of heavy metals, and her ambitious project linking various scientific disciplines to the basis of elements of the periodic table exemplify her uniquely innovative and effective approach to science communication.
