🚨 @fftedudatalab.bsky.social shows only 9% of disadvantaged pupils with strong primary maths skills achieve a B+ at A-Level.

The research shows where pupils fall away. Our own research shows why: disengagement arrives early in secondary school.

👉 Read more in our CEO’s op-ed in Tes or our blog.

What can employers do to create a more inclusive environment?

In a new guest blog, Dr Frankie Doddato, physicist at Lancaster University, writes on the vital role of the National Association of Disabled Staff Networks, and its STEMM Action Group:

A quote overlayed says "it's through change that science progresses, and good science is diverse and inclusive, including for disabled people. We are here, within science as scientists." - Dr Frankie Doddato

It has been great to catch up with Wookyung and discuss our ongoing collaboration in person, as his position as JSPS Invitational Research Fellow at the University of Tokyo means that our conversations are mainly online.

Well done, Wookyung!

Jan Grabowski @jan-e-grabowski.bsky.social · Jul 17

A very special day today, celebrating the achievements of my former student Wookyung Kim on the occasion of his PhD graduation at @lancasteruni.bsky.social. Congratulations to him and all the graduates from the Faculty of Science and Technology and especially the School of Mathematical Sciences.

Will this be in a magazine issue, or online only? If the former, do you know which? Thank you!

Factors Affecting Public Engagement by UK Researchers 2025
Introduction
About the study

The Royal Society has commissioned Technopolis to conduct a study on the factors affecting public engagement by UK researchers in 2025.

The primary objective is to understand…
What public engagement means and entails in 2025
The value and significance of public engagement
Enablers and barriers, and opportunities and risks of public engagement
Effective implementation and support strategies
How these elements have changed over time

Very enjoyable day in Manchester today, giving the Algebra seminar at the Department of Mathematics at @uniofmanchester.bsky.social, talking about my work with Matthew Pressland (Caen) and catching up with a variety of colleagues. Plus a bit of trying to implement the old classic (time+coffee=maths)

Today I was asked in an interview about folks who use the weirdness of ✨quantum✨ to hawk pseudoscience junk. I think that kind of grift proliferates because of a big misunderstanding a lot of folks have about quantum mechanics, which is not really their fault!

I can try... The story arc is neat and satisfying (but I don't want to give anything away so won't say more than that) but really it's the whole ensemble - characters, backdrop, plot, language. Plus a few bits of social commentary for good measure.
