But is it art?
Today I started Astrophysics with my second year classes so built the solar system in interactive physics (obviously). The point I try to make is how hard it is to work out that the planets are orbiting...
Electric eel
Yesterday Abel (age 6) told me about a video on youtube that shows an electric eel lighting up a Christmas tree. When I was 6 I was also interested in electric eels but haven't really thought so much...
Little and Large
The other week an interesting question was posted on the OCC. A small ball is placed on top of a big one and rolls down. At some point the small ball will leave the surface of the large one, at what time...
Thermo now dynamic
I've just finished preparing a set of instructions so that my first year classes can learn about thermodynamics in a more interactive way. The idea is that they build up their own GeoGebra PV curves to...
Carnot, cycle yes
Some time ago I made a simulation of Adiabatic and Isothermal changes in GeoGebra but it was a bit clumsy when attempting to model a Carnot cycle. Take 2: the new improved simulation of the Carnot cycle....
A billion words?
If a picture tells a thousand words how much does a 3D animation say? My experiment making 3D PV curves with GeoGebra....
Spinning stopper
A spinning stopper is not something that stops a body spinning, it's a bottle stopper that rotates on the end of a string threaded though a glass tube with a mass hanging on its end. All sounds rather...
Fibre tree
I was at my brothers house the other day and his Christmas tree lights caught my attention. Optical fibres had been used to transfer light from the base to the ends of the branches but what interested...
Time and tide is waiting

Nazare in a bucket
When I worked at Atlantic College my service (as in CAS) was life guarding which meant I spent a lot of time surfing. Fjords aren't known for their waves so I don't get to surf so often but still like...
