I'm a PhD student at Queen Mary, University of London. I'm interested in modern approaches to scattering amplitudes, in particular twistor methods and integrability.

comment Collision of Discs and Snooker Kicks
Hi Joce, thanks for your comment. I think I didn't make the setup clear enough. In problem two the balls are rotating about an axis parallel to the plane of the table. In other words they have "topspin" or "backspin". So this example is just like the previous one, only now we have gravity and the table surface to contend with. Does this make sense? Thanks again!

Yes - that would also be a correct way of saying it!

Sorry - I misread your question. My answer was incorrect so I've deleted it! Apologies for the confusion.
