And a 15% easier in antispin vs 15% harder spin throw definitely means sufficient difference to alter play... and a lot more missed throws due to differences in ball performance. |

Re: O'Neill Cylinders
I don't think that "15% easier" is an accurate characterisation. If you throw the ball the same it will go ~6% further. But since a good pass in Rugby is much shorter than the distance one can easily throw a Rugby ball that doesn't really help much. A cross-wind makes passes faster or slower, which does matter. The Coriolis effect only makes them come in a little low or high: that requires practice to adjust for, but equally to east or west.

Re: O'Neill Cylinders
Yeah, we don't do much with it in-setting. It's just there as background material and a Dire Warning To Future Generations to not let any other company pull the same sort of stunt.

Re: O'Neill Cylinders
I built a little calculator for the thickness of the structural hull, mass of the hull and contained atmosphere for a rotating cylindrical habitat, as functions of the length and radius, the "gravity" and air pressure, the mass-per-unit-area of the shielding, armour, landscaping, and fittings, and the strength and density of the structural material. It's an Excel workbook with no macros.
Just at the moment the list of possible building materials is a bit incomplete and some of the values for strength questionable. I put it on Dropbox for review and personal use: https://www.dropbox.com/s/7iilf35hdx...ator.xlsx?dl=0
