Neat. I noticed that the summary for this popped up on Egan's site a few months back, but there wasn't nearly enough detail for me to wrap my head around the premise. Gonna take another look at it now.
For anyone who finds this interesting, you might want to check out Christopher Priest's Inverted World, which is based on a vaguely similar premise. (Although much more closely tied to the "real world", and not nearly as mathematically rigorous.)
- teraflop 10y agoJust posting a follow-up comment to say that the interactive simulation is really the highlight of this set of pages. I was expecting a trivial demo widget, along the lines of the animated GIFs in the article, but it's actually a full 3D rigid-body simulation. Playing around with blocks and ramps in a browser does a great job of taking the mathematical analysis given in the article, and making it at least somewhat intuitively understandable. But on the other hand, it doesn't exactly make a convincing case that a world built according to these rules could ever be stable! http://gregegan.customer.netspace.net.au/DICHRONAUTS/02/Interactive.html http://gregegan.customer.netspace.net.au/DICHRONAUTS/02/Inte...
