Read at last the (disappointing) last tome of Christelle Dabos’ The Mirror Visitor, The Storm of Echoes, as I find the unravelling of the story unbearably slow and poorly constructed, contrasting with the earlier volumes where the universe building was central to the appeal of the series. Here it is collapsing, literally and figuratively. Without risking spoilers, I can only point out to the vagueness of the endless hesitations of the central character between multiverses. One volume too many imho! Also read a series of two novella, Our Lady of Endless Worlds, by Lina Rather, a very light story of a Catholic nun convent travelling on a spaceship. Nothing as enticing as Becky Chambers’ Wayfarers, but enjoyable as train read! At last, went through Murder as a Fine Art, by David Morell, which botches a poor murder enquiry out of the true story behing De Quincey’s essay, featuring the writer and his daughter in a lukewarm pot of wikipediesque infodump and anachronous attitudes. (Could you imagine Victorian strangers discussing the average waist sizes of men and women?!)

Watched the third season of the Witcher, which is also the last season with Henry Cavill. This short season felt sluggish and soapy, although somehow in tune with the book(s). It seemed as if the characters had lost some of their ambiguity, esp. Yennyfer, and hence of their appeal. The final show still had some appeal thanks to its time loop construction. I also had a look at the prequel, Blood Origin, which proved a mistake, as it is terrible (apart from the Icelandic landscapes!).

the latest Significance: Astrostats, black swans, and pregnant drivers [and zombies]

Reading Significance is always an enjoyable moment, when I can find time to skim through the articles (before my wife gets hold of it!). This time, I lost my copy between my office and home, and borrowed it from Tom Nichols at Warwick with four mornings to read it during breakfast. This December issue is definitely interesting, as it contains several introduction articles on astro- and cosmo-statistics! One thing I had not noticed before is how a large fraction of the papers is written by authors of books, giving a quick entry or interview about their book. For instance, I found out that Roberto Trotta had written a general public book called the Edge of the Sky (All You Need to Know About the All-There-Is) which exposes the fundamentals of cosmology through the 1000 most common words in the English Language.. So Universe is replaced with All-There-Is! I can understand and to some extent applaud the intention, but it nonetheless makes for a painful read, judging from the excerpt, when researcher and telescope are not part of the accepted vocabulary. Reading the corresponding article in Significance let me a bit bemused at the reason provided for the existence of a multiverse, i.e., of multiple replicas of our universe, all with different conditions: multiplying the universes makes our more likely, while it sounds almost impossible on its own! This sounds like a very frequentist argument… and I am not even certain it would convince a frequentist. The other articles in this special astrostatistics section were of a more statistical nature, from estimating the number of galaxies to the chances of a big asteroid impact. Even though I found the graphical representation of the meteorite impacts in the past century because of the impact drawing in the background. However, when I checked the link to Carlo Zapponi’s website, I found the picture was a still of a neat animation of meteorites falling since the first report.
