This is an incredible price for a brilliant book! Great to support STEM and science learning in school, for adults who love science, adults who never really ‘got’ science, and curious people everywhere! 👇
Friends! I have a lot of you to thank for fact that The Works have sold out of the massively discounted copies of "Why Don't Things Fall Up?" online. Apparently this means they've sold ~ 2000 copies! The book is still available at the stupid price of £3 or less in their physical shops and on Amazon

Alom, Generous to a fault and a great writer.
I’ve bought a whole load of these and if, for *any* reason, the price is still prohibitive for you, I’d be happy to send you a FREE copy.

Pretty sure that if anyone knows how to make a philosopher’s stone, it’ll be Phil. Buy this book and find out:
This feels a bit like when your child does something amazing and you feel like you want to take the credit but can't really. My new book Alchemy: An Illustrated History has arrived, and it looks *gorgeous*.

Little demonstration of Brownian motion : a larger and heavier tracer particle moves through a fluid. At about halfway, the smaller particles are faded out, leaving only the tracer particle visible.

I often recommend doing the “radioactive balloon” demo (charge balloon, hang it up to collect daughter ions of natural decay processes, wait, measure) when talking about background. Here’s the trace from before, to after placing the deflated balloon next to the Radiacode.

Another shot of the Radiacode app. The green is a 7day background reading I took at home, in modern brick built. The yellow is current picture building up underground in an old stone home in Devon.

Not sure if I shared this here - this is my new Radiacode detector the WWII clock that lives (in a case) on my desk at home. Using it with the app is even better.

There you go @phetsims.bsky.social - Imagine what you could do with all the data from device on board sensors...
We‘d be in… 🎈
It’s superb work you do! If I were rich I’d fund you out of pocket. (Actually if I were that wealthy I’d pay you to integrate with the other great essential resources @phyphox.org and @geogebra.org )

This is a great demo for a really, really important point. All too often electricity is presented as independent of the thing we call "static". It's all just Coulomb interaction.
Great demo linking static electricity to current. Thank you to Mark Harrison for the tip 🙂

This is a very nice example of doing radioactivity without a formal source.
I've been trying to replicate a #radiation experiment using an electrostatically charged balloon to accumulate Radon decay products giving an approximation of a #decay curve for #halflife.
I finally did it!

This is a real a genuine concern. The phET sims are an internationally important resource
So for the past 15th years or so, maybe longer, I've been using phET simulations in my classes. The NSF just cut at 1.5 M grant to phET because I guess the government doesn't find these educational tools worthwhile anymore. Cool.

Apparently red is the most common colour on a national flag, but not everyone uses the same red. (I'm interested why it's so common). It's not my idea then but I was able to make it with R. Having ideas like this is really helping me learn the language. I wonder what I should do next.

New toy for pointing out stars. It’s supposed to be sub 1mW. I really don’t think it is. Remember folk, these are not toys, they’re jolly dangerous and it is criminal to sell lasers under rated like this. If anyone has a good source for a genuinely 1mW green laser pointer, please let me know.
