So sad to see the loss of another laser pioneer with the passing of Orazio Svelto on 10 Jan. As well as being an inspiring scientist who helped create the European ultrafast community, he was gracious and generous with his time and support for international science. www.ansa.it/canale_scien...

Wonderful news and heartfelt congratulations to UCL prof Polina Bayvel on being named a Dame Commander of the Order of the British Empire (DBE) in the 2026 New Year Honours List. A truly outstanding and well-deserved achievement. Congratulations, Polina!

Those outside the field really don't pay enough attention to what goes on in condensed matter. Indeed, even the excellent DPG Quantum History Wall didn't include yesterday's Nobel Prize winning work on tunnelling in its list of quantum milestones of the 1980s! www.quantum-history.de

I just had some fun verifing the 1/r potential drop from a plasma ball. The idea is from @simonpoliakoff.bsky.social
and his video is here: youtube.com/watch?v=crW7... To get close to the ball (5 mm) I used a 10kOhm feedthrough terminator which yields around 25 V peak-peak !

Impact factors certainly do not tell the whole story, but in what is more or less an annual tradition, I have compiled a list for some physics/optics journals. Note that there are truly excellent articles in all of these journals and different journals play very different roles in the community.

Just learned that the Wii remote triangulates position via IR sources in the bar you place on the TV. Most phone cameras allow you to see the emitters (top) but in fact you don't need them. You can replace the bar by two candles and it works just fine! Am sure most people knew this already ...

Our library holds a rare copy of the proceedings of the 1911 Solvay Conference on physics, and I enjoyed looking through it (very carefully) today. As well as the amazing discussions and pictures (these are from Perrin) it seems a previous reader had been practicing their French at the same time!
