Today is Lise Meitner's birthday, as well as Marie Curie. I wrote this blogpost about Meitner and her life a while back. Let's celebrate the woman who 'never lost her humanity'. occamstypewriter.org/athenedonald...

Great news for Michael Berry who has received the Isaac Newton medal of the IOP. What I absolutely love about his work is that it cuts across so many different areas of physics - from the foundations of quantum physics to understanding the rainbow. physicsworld.com/a/theoretica...

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

Very sad to hear that the great soliton pioneer Akira Hasegawa has died on June 22. His work truly was revolutionary in so many ways and impacted so many different fields. An obituary from Columbia is below. www.apam.columbia.edu/memoriam-pro...

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!
