My Correct Views on Everything

Review: My Real Children

Book cover: My Real Children My review of Jo Walton’s My Real Children is now up at AE. My Real Children came out a year ago, but it just won the Tiptree Award, which made doing the review more timely; AE’s review policy doesn’t limit itself to new releases in any event.

Rereading the book for this review was an interesting experience, as was writing the review. This is the kind of book that could generate several different reviews that each focused exclusively on a different subject. It wasn’t just that I was scratching the surface — I was scratching just one surface.

Taxonomic Changes to Crayfish, Swamp and Earth Snakes

I’m always afraid to check the CNAH website: there’s always some new study that renames or reclassifies everything. It’s been a while since the natricine snakes have been done over, though. A 2013 phylogenetic study of two North American natricine genera — the glossy and crayfish snakes (Regina) and the earth snakes (Virginia) — concludes that they’re not monophyletic. They split off two crayfish snakes and group them with black swamp snakes in a new genus, Liodytes, and split the earth snakes into two monotypic genera.

Here’s a table of all the changes:

   alleni (Striped Crayfish Snake)
   grahamii (Graham’s Crayfish Snake)
   rigida (Glossy Crayfish Snake)
   septemvittata (Queen Snake)

   pygaea (Black Swamp Snake)

   striatula (Rough Earth Snake)
   valeriae (Smooth Earth Snake)
   alleni (Striped Swamp Snake)
   pygaea (Black Swamp Snake)
   rigida (Glossy Swamp Snake)

   grahamii (Graham’s Crayfish Snake)
   septemvittata (Queen Snake)

   striatula (Rough Earth Snake)

   valeriae (Smooth Earth Snake)

From what I’ve read this isn’t exactly a surprise (at least insofar as the crayfish snakes are concerned). But I’m not sure I like the notion of changing the common names (e.g., “crayfish snake” to “swamp snake”) whenever there’s a taxonomic change: that’s more confusion than is strictly necessary, especially considering how much back-and-forth there can be.

‘1491’ Is Becoming a TV Series

Book cover: 1491 One of my favourite books, 1491: New Revelations of the Americas Before Columbus, is being made into a documentary TV series. The book’s author, Charles C. Mann, confirmed on Twitter last week that principal photography had begun. There isn’t a lot of information out there yet. It’s being written and directed by Barbara Hager, whose Aarow Entertainment will be co-producing it with Animiki See Digital Production. Eight one-hour episodes are being filmed this year for broadcast on APTN in 2016.

1491 is a book-length debunking of a lot of shibboleths about the pre-Columbian Americas. It paints a picture of a heavily populated hemisphere filled with sophisticated societies that transformed the landscape around them. A TV version offers an opportunity for more people to have their heads explode, like mine did in 2006. (See also my review of its sequel, 1493.) Via Kottke.

Google Maps Edits Cause Embarrassment

Some embarrassment for Google Maps last week, as they were forced to apologize for an image of the Android mascot peeing on an Apple logo that turned up on the map near Rawalpindi in Pakistan. To say nothing of the phrase “Google review policy is crap” etched into nearby Takht Pari Forest. Both have since been removed. Boing Boing, the Guardian, The Verge.

To be fair to Google, crowdsourcing map data does have its pitfalls: OpenStreetMap has to deal with this sort of thing all the time. You have to have something in place to deal with bad-faith edits. None of the edits I’ve made to Google Maps went through without someone reviewing them, so I’m surprised that this could happen. That said, when you need your map updated fast (such as during natural disasters like yesterday’s earthquake in Nepal), it’s hard to beat crowdsourcing.

As always, it’s important to keep in mind that all online maps have their shortcomings.

Map of Canada Changes Depiction of Arctic Sea Ice

Map of Canada

The federal government’s new map of Canada, part of the Atlas of Canada reference series, came out this week. Among the changes between it and its predecessor (which came out in 2006), one in particular is drawing attention. Ivan Semeniuk in the Globe and Mail:

Whereas the older version of the map showed only that part of the sea ice that permanently covered Arctic waters year round at that time, the new edition uses a 30-year median of September sea-ice extent from 1981 through 2010. September sea ice hit a record low in 2012 and is projected to decline further. The change means there is far more ice shown on the 2015 version of the map than on its predecessor.

The changes can be seen below: the 2006 map is on the left, the 2015 map on the right.

Differences in sea ice between 2006 and 2015 maps of Canada

Now as Semeniuk’s piece points out, neither way is wrong. But all maps have a point of view, and it’s naive to think that this change was made in a value-neutral environment: this was the result of a conscious decision. The reason for that decision — that’s what’s interesting.

Valentina Lisitsa and Artists’ Social Capital

Here’s my take on the Valentina Lisitsa affair.

Lisitsa, a Russian-speaking, Ukrainian-born classical pianist, was scheduled to perform Rachmaninoff’s Piano Concerto No. 2 with the Toronto Symphony Orchestra last week, but she was dropped by the TSO over a series of offensive tweets about ethnic Ukrainians and the ongoing conflict in eastern Ukraine. Lisitsa has a social media presence — her reputation was basically made on YouTube — and the inevitable online shitstorm ensued. That shitstorm swallowed up Stewart Goodyear, the pianist tapped to replace Lisitsa, who had to bow out in turn.

New Moon Maps

Topographic Map of the Moon (Hare et al.)

Two stunning maps of the Moon have been released by the USGS, both based on data collected by the Lunar Reconnaissance Orbiter: one an image mosaic assembled from visual imagery, the other (above) a colour-coded topographical map derived from laser altimeter data. Via io9.

Chopin’s Preludes on a Pleyel

Performing classical music on the instruments of the era (which differ quite a bit in sound and construction from their modern descendants) has been a thing for a while. This Kickstarter project is in that vein: its goal is to have Kimiko Ishizaka record Chopin’s Opus 28 Preludes on an 1842 Pleyel piano in original condition. A Pleyel was Chopin’s piano, so you can appreciate the historical significance of this project. I know the Op. 28 Preludes quite well; it’ll be interesting to hear the difference (this page includes recordings of Chopin’s Nocturnes being played on an 1836 Pleyel). As for the Pleyel company itself, it stopped making pianos in 2013; it seems to have ended its days as a very upscale brand. Via Boing Boing.

Back to Brontosaurus

Brontosaurus (Marsh)

A new paper has resurrected Brontosaurus as a valid taxon. The cladistic study of diplodocid dinosaurs concluded that there were substantial differences between Apatosaurus and Brontosaurus: the former is even more robust and has a distinctly thicker neck. News coverage: Nature, Scientific American, Brian Switek at Smithsonian.
