The best teacher I never had
I'm with Bill on this one. Gates notes...
Football vs physics
The caption "football defies physics" caught my eye. Nothing can defy physics, if it does then the physics is wrong and it has to be re-written. Physics is just describing the real world and you can't...
Is it or isn't it?
I'm not even going to try to explain all the interesting physics in this clip but there are some great examples of balancing torques and fluid mechanics (above and below the water). Bernoulli might apply...
Chandelier
I've just been writing activities for the fluids part of the engineering option, there's quite a lot considering its just the additional HL stuff. One of my ex students Davide Kleiner, who is an engineer,...
Start with the misconception

Year of the pig
Actually it's the year of the sheep but I don't have any flying sheep so every year is a pig year to me. (Next year is the year of the monkey but we have to wait until 2019 for an official year of the...
What's that
Maybe this photo needs some explanation. It's a magnet held up close to the diffraction pattern caused when electrons pass through a carbon film. You know, one of those Teltron tubes you're never allowed...
Angular snowmentum
We've had almost no snow all winter then we got this lot in a couple of hours. It always causes great jollity amongst the students especially the ones who haven't seen snow before. Great jollity normally...
New headers
Even though it's not spring yet (-15°C here in Norway) I have been doing some spring cleaning on the site and have reorganised the top navigation bar. Don't worry though everyhing under the headers is...
Driven up the wall
I spotted this on facebook and although I don't agree with all the comments like, "my missus has been driving me up the wall for years", it's an interesting application of a basic principle of physics....
