Proud teacher
I am proud to announce that one of my students, Nikita, has just won the Norwegian Physics Olympiad. For those who can read Norwegian here is an article from our local paper. Firda...
I submit
I've done it.I've submitted my sample to Ibis which to any non IB people reading this, is not as dodgy as it sounds. It was all very easy but you have to be prepared. Here are some tips / observations....

No change is conservation
Some of my first year students were experimenting with the conservation of angular momentum and thought of pulling a mass off a rotating platform as it was spinning. I must admit that I was expecting...
Ring of charge
Paul Tonkinson's physics students have made an interesting observation. If you make a sphere of charge using the PhET charges and field simulation you find the field inside isn't zero. I tried it myself...
Fine man diagram
This is the sort of nonsense I have to put up with from my students. I don't think he looks particularly fine. Looks a bit grumpy to me. Maybe its because he's imprisoned behind those bars....
Difficult diagrams
It's always difficult to explain something without a diagram and sometimes it's difficult even with one, the radio interferometer telescope is a case in point so I thought I'd make a GeoGebra simulation...
Dragon drop
I've been playing with the drag and drop possibilities with GeoGebra. Thought it might be useful for practicing rearranging equations. Try making ρ the subject (on the left)...
