Review of 'Permutation City (Subjective Cosmology #2)' on 'Goodreads'

This book takes some time to absorb, and I'm probably doing it a great injustice by reviewing it so quickly after finishing it (and with such a rushed reading by such an uneducated reader). Greg Egan clearly knows what he's talking about when it comes to theoretical physics, and I certainly don’t, so the main bits of Permutation City intimidated me to a point that I may have taken the book too seriously. Some of the reviews I've read now that I've finished have lead me to believe some irony and perhaps even humor were completely lost on me in my reading.

But aside from the subtle and scientific points I missed (of which there was little to no overlap), there was plenty left to entertain and impress me.

Review of 'Axiomatique' on 'Goodreads'

Bon, je n'arriverai pas à tout faire en un coup : les nouvelles sont trop denses, et je sors trop chamboulé de chacune pour pouvoir me permettre d'attendre la fin de cette lecture. Voici donc mes avis sur chacune des nouvelles qui composent ce qui est pour moi un authentique chef d'oeuvre.

L'assassin infini

J'ai à peu près compris la base de cette histoire : dans un multivers connu, c'est-à-dire où on sait que c'est un multivers, il existe une drogue permettant de "voyager" dans les univers parallèles. Il existe logiquement une police empêchant ça d'une manière radicale, conçue fort logiquement autour de personnes stables dans les univers parallèles.

Ca part franchement très fort, avec des espèces de gradient de décalage et des observations triangulées. Mais la conclusion m'a laissé littéralement pantois par la dimension du piège tendu, et la présence tout à fait inattendue d'un ensemble de Cantor.
