I’m shutting down the Discord server, because nobody uses it. Also, do not forget about the A-Level Easter Revision Session this morning!

Apologies and a confession
Earlier today I announced that I would be offering biology and chemistry tuition. I am afraid this was an April Fool’s Day prank. See blog post for more.
Coming soon…
Fascinated by counting how many drips of one liquid have to be mixed in another before the mixture changes colour? Realised that sneezing on a petri dish is a dream come true? Coming soon, support for the lesser sciences! See blog post for details.

Badges!
If you see me out and about and recognise me, please do come and say hello and if I’ve got some of these badges in my pocket I’ll give one to you.
Easter revision sessions!

Deriving the speed of light from Maxwell’s Equations
I thought it’d be good to show my A-Level students how to model an electromagnetic wave using a sinusoidal wave function for the electric and magnetic fields, and how these can be substituted into Maxwell’s Equations to derive the speed of light. There are a few ways to derive the speed of light from Maxwell’sContinueContinue reading “Deriving the speed of light from Maxwell’s Equations”
The visit to CERN
Over the half term I ran a school trip to CERN in Geneva. I’ve run the trip many many times now. This time, however, I ran the trip whilst suffering from bronchitis! With fistfuls of cough sweets and antiinflammatories, I got through it. While I was there, I decided to do a few live streams.ContinueContinue reading “The visit to CERN”
The end of half term
Today’s the end of the half term, so I need a break. I won’t be blogging every day, but I’ll try to post some stuff during my school trip to CERN. As a parting gift before our short recess, here is the simple pendulum time period equation derived using Lagrangian mechanics. I’ve also managed (atContinueContinue reading “The end of half term”
The unboxing of my new HP 15c Collector’s Edition calculator
Happy Valentine’s day to me! I treated myself to a calculator I’ve wanted for many years, a HP 15c (well, the collector’s edition version. I cannot justify the price tag of the original) Screenshot from eBay, comparing the price of an original HP15c with an HP15c Limited Edition, 2024-02-14 20:20 Below I have embedded myContinueContinue reading “The unboxing of my new HP 15c Collector’s Edition calculator”
