Time spent improving human connection and the subtler, softer side of teaching is never wasted. I couldn't agree more about the need for humanity in lessons, we need less robo-teaching and more joy and enthusiasm. If we teach young people to delight and play in our subjects they will always thrive.

Shout out to everyone doing science communication for the greater good while some of the biggest names in science were conspiring to spread white supremacy and misogyny. Maybe don’t invite those people to your festivals anymore though?

Female Physicists... A small effort to rebalance the textbook.

A few role models to add to your teaching. #iTeachPhysics

Colourful image from the webpage of the Royal Society. Background is a mix of images of electronic circuits and silicon wafers. Text reads: "Welcome to the Royal Society. We are the independent scientific academy of the UK, dedicated to promoting excellence in science for the benefit of humanity."

FOR THE RECORD: one year on, I lay out clearly how Elon Musk FRS has breached the @royalsociety.org’s code of conduct, why the Society’s failure to defend its values has been so damaging, & what they need do to recover their standing in the scientific community. occamstypewriter.org/scurry/2026/...

The easiest way to do it is to add highlighter ink to water, then bleach the colour with some citric acid/lemon juice

Made up a batch of Uv fluorescent, clear ink today. I’d almost forgotten how pretty it is.

They look great! I wonder if pasco will send them to Africa?

Ed tech is profitable. It is also mostly useless Independent research identifies few learning gains

Blistering piece on ed tech in @economist.com.

‘Although ed-tech companies tout huge learning gains, independent research has made clear that technology rarely boosts learning in schools—and often impairs it.’

Hot on the heels of talking about teaching physics with whatever you have, what about this Doppler effect Saucer from what used to be my local cafe!

Kraul Candle Seesaw Kit with Bears Kraul Bear Candle Seesaw Kit. As long as the candle is burning the little bears seesaw at a gentle pace. Marvel as they appear to throw the ball from one to another. Assembly from 10 years. Use under ...

Amusingly this was in the CPD and the first draft and I thought someone would object so I took it out!

I like to have one that has a cool head (like normal) and one with the felt removed and a hairdryer on low at the base. This heat engines this is another fave: myriadonline.co.uk/kraul-bear-c....

#ITeachPhysics benefits from using everyday items - not just in demystifying the lab but also injecting some creativity. I used to do a CPD session on creative teaching and I've written it up here. Hopefully you'll find it interesting #physics #teaching
