Geometry might well kill them in the end, but only a rigorous understanding of its principles could make their situation intelligible, let alone survivable. That quote comes from Part 4 of this novel, but it encapsulates what’s intriguing and (at least potentially) frustrating about the story—it’s about spacetime geometry. I’ve written about Greg Egan before, … Continue reading Greg Egan: Dichronauts

Coriolis Effect In A Rotating Space Habitat
In a previous post describing the Coriolis effect, I mentioned its relevance to space travel—if a rotating habitat is being used to generate simulated gravity, Coriolis deflection can interfere with the performance of simple tasks and, at the extreme, generate motion sickness. As an example of the sort of effect you could expect to encounter, … Continue reading Coriolis Effect In A Rotating Space Habitat
Coriolis
When I was a solitary, bespectacled and distinctly oikotropic child growing up in Dundee, I was fascinated by the little roundabout, like the one pictured above, in the play area of my local park. While my compatriots were trying their best to kill or maim themselves by using the swings, the slide and the witch’s … Continue reading Coriolis
Saying “Centrifugal” Doesn’t Mean You’re A Bad Person
Despite its daunting size, the huge structure was in fact a very simple machine, essentially a massive slingshot exploiting the rotation of the KBO to hurl objects into space. Slugs of refined, processed matter were loaded into open-topped buckets at the KBO’s surface. For the first hundred kilometres, they were hoisted up the length of … Continue reading Saying “Centrifugal” Doesn’t Mean You’re A Bad Person
Greg Egan: The Orthogonal Trilogy
Greg Egan is an Australian mathematician who has been writing hard science fiction for thirty years, although his hard science is the stuff that sits at the borderland of philosophy: the relationship between mathematics and reality, the nature of consciousness, the implications of quantum mechanics. Previous novels have involved speculations on what life might be … Continue reading Greg Egan: The Orthogonal Trilogy
