Transient phase space showing radio luminosity versus the product of timescale and observing frequency for different transient source classes, following Cordes et al. (2004). This is a figure from Murphy & Kaplan (2025) published in PASA. See the paper text (Figure 1 caption) for a full description.

The final version of our Dawes Review on the Dynamic Radio Sky is now published!

Everything you need to know about what causes radio transients: how we detect them, the history of radio transient surveys, and what new widefield radio telescopes will do.

Such a worry -- physics underpins science. If students don't choose to study fundamental subjects like physics, will Australia continue to be a leader in science?

Participation in Australian high school #Physics is declining!

The proportion of Yr 12 students studying physics fell from 14.9% in 2015 to 12.1% in 2023; gender ratio unchanged.

(Luckily this hasn't impacted the number of students studying Physics @sydney.edu.au, but it is a broader issue).

A smartphone is not all that different in shape from a skateboard, in Australia, they are willing to take risks, and so “The mobile phone as a free-rotation laboratory” was born, www.physics.usyd.edu.au/~wheat/paper... (for tl;dr, there is a video via the DOI link). 2/3

The Faculty of Science student awards 2025. Science is amazing and our students are the future which is more
amazing still.

In an era that is very cynical about higher education, it's great to see students from a range of cultural and educational backgrounds working together, sharing their experiences and recommending books to read. Both on campus and online.

Highly recommended!
They have giant Redwoods, and so much else.

That's the Wilkinson axis!
