Subrahmanyan Chandrasekhar was born #OTD in 1910. He established an upper limit on the mass of stars that end their lives as white dwarfs. Above this Chandrasekhar Limit – about 1.44 solar masses – stars eventually explode and then collapse into a neutron star or black hole.

Interested in astronomy education research? Join us for our next #IMPRESS seminar on Oct 25 at 9am CEST💫 @JuliaWoithe & I have invited the wonderful Saeed Salimpour IAU Office of Astronomy for Education to discuss his framework for analysing representations in cosmology education🤩 indico.cern.ch/event/1176822/

New publication! The data was collected from the Primetime-courses at the Dept. of Physics Faculty of Mathematics and Science. Continuation of excellent collaboration between two faculties University of Jyväskylä (and now LET UniOulu Finland as well)! 😎 #JYUnique

Such a pleasure to discuss the use of social semiotics & joint action theory with our guests Eduardo Mortimer & Andrée Tiberghien at our ESERA #SIG6 journal club on languages & literacies in #ScienceEducation. You can find the paper we discussed here: tandfonline.com/doi/full/10.10…

Really looking forward to this!

😁😁 over the moon! so great that physics education and PER are being recognised ✨

"How does objective reality emerge from the palette of possibilities supplied by #QuantumMechanics?" asks @philipcball in his latest piece on quantum physics & explains why physical-collapse theories appear to be collapsing themselves via Quanta Magazine🤓 quantamagazine.org/physics-experi…

Very honoured to be the 1st Australian awarded the international Blaise Pascal Medal in Physics 2022 by the European Academy of Sciences EurASc in Brussels. As a teenager I was in total awe of Pascal as a scientist! Australian Institute of Physics Australian Academy of Science @WomenSciAUST ourANU OzGrav

Our Pet Photons will be making an appearance at the Ozgrav stall. Find out what makes photons so weird, how we use them in gravitational wave detections, and explore space in VR!

New paper on remote physics teaching in Norway during the pandemic. Students lost out on training key scientific practices such as experimentation and talking physics. Well done, Nikolai Bjurholt. #iteachphysics Fysikk UniOslo iopscience.iop.org/article/10.108…

When you have yeast transformations at 6, but a Halloween party at 7. #phdchat

Such a privilege to be able to hop into the opening session of Department of Science Education's #PhD course on qualitative methodologies and listen to Justin Dillon Katie Wade-Jaimes Lars Ulriksen who share their thoughts on the 'why' and 'for whom' of #SciEdu research 🤩 #qualmethod22

Helllo Department of Science Education again, I am very honored to attend the PhD course about qualitative method in science education. Nice to meet great researchers Justin Dillon @HHolmegaard Katie Wade-Jaimes Lars Ulriksen Amy Smith and old friend Dr Magdalena Kersting ☺️#qualmethod22

Are there tools of the imagination? In this paper I argue that visualizations, thought experiments, models, computer simulations, and metaphors are such tools, and I discuss how they can be evaluated using a single framework (consequentialism). link.springer.com/article/10.100…
