I give up
The problem with the spiral is that the acceleration increases too rapidly since the field strength and the angle of the slope increase as the ball gets closer to the centre. To counteract the increase...

EE update
The deadline for first draft is this Wednesday so I thought I'd give an update on progress. Many people think that 10 EE's is too many but so far it's not been a problem. My classes are completely student...
SUPer EE
Raj threw caution and my advice to the wind and decided to write his EE on the relation between the angle of a hydro foil and the lift. He took some time perfecting his experiment but in the end got some...
More slow physics - Single slit diffraction
One of my students said that he liked my videos and found them relaxing. That was just the sort of encouragement I needed to return to my slow physics video project. These are real time, non edited videos...
Chromatic Aberration
Khoa from Vietnam is writing his EE on Chromatic aberration and the achromatic doublet. Actually making an achromatic doublet is rather difficult so he is focussing on building a simulation. You can simulate...
