the witcher

As I read (some of) Andrzej Sapkowski‘s books, and then watched my son play the derived video game, I took the opportunity of the break to watch the eponymous Netflix series. Which I found quite decent and entertaining, given that the books were not unforgettable masterpieces but enjoyable and well-constructed. The New York Times was quite dismissive in its review of the show, seeing as a cheap copycat of Game of Thrones when the books were written earlier than Martin’s unfinished no-end-logy. The Blaviken battle scene in the first episode is certainly on a par with GoT most fighting moments, while lasting a few seconds. And the actor playing Geralt manages to convey much more in a few grunts than, say, Kit Harington’s permanent cocker spaniel sad face!!! The budget here is clearly not the same as HBO’s investment, with some exterior scenes looking a wee bit bare (just as in the BBC’s rendering of Jonathan Strange & Mr Norrel). But, again, nothing there to dim the appeal of the series (although they could have cut on the definitely gratuitous softporn moments!) and a plot gradually rising from the fragmented time line and the apparently unrelated subplots, which is also a feature of the books, made of short-stories vaguely glued together. I am hence looking for the second season, hoping the GoT curse does not extend to this series. ( also published a highly critical review of the show. And of the books, which are incidentally not published by Tor!)

Sherlock [#3]

Posted in Books with tags , , , , , , on March 14, 2015 by xi'an

After watching the first two seasons of the BBC TV Series Sherlock while at the hospital, I found myself looking forward further adventures of Holmes and Watson and eventually “bought” the third season. And watched it over the past weekends. I liked it very much as this new season distanced itself from the sheer depiction of Sherlock’s amazing powers to a quite ironic and self-parodic story, well in tune with a third season where the audience is now utterly familiar with the main characters. They all put on weight (mostly figuratively!), from Sherlock’s acknowledgement of his psychological shortcomings, to Mrs. Hudson’s revealing her drug trafficking past and expressing her dislike of Mycroft, to  John Watson’s engagement and acceptance of Sherlock’s idiosyncrasies, making him the central character of the series in a sort of fatherly figure. Some new characters are also terrific, including Mary Morstan and the new archvillain, C.A. Magnussen. Paradoxically, this makes the detective part of the stories secondary, which is all for the best as, in my opinion, the plots are rather weak and the resolutions hardly relying on high intellectual powers, albeit always surprising. More sleuthing in the new season would be most welcome! As an aside, the wedding place sounded somewhat familiar to me, until I realised it was Goldney Hall, where the recent workshops I attended in Bristol took place.

on the Piketty craze [not a book review]

Posted in Books, University life with tags , , , , , , on June 15, 2014 by xi'an

The controversy about the data in Piketty’s Capital in the 21st Century fed a dozen articles in the NYT last week, not to mention other newspapers… To the point of Bloomberg producing this parody of a glitzy popular press cover. I have not read the book, nor intend to read it, but I find the buzz and controversies rather surprising. (Thomas Piketty will actually give a public BBC interview in Paris-Dauphine and in English two weeks from now, on June 19.) Indeed, the book sounds to me like a data analysis of extensive (and elaborately processed) datasets rather than the construct of a new economic theory. And I could not see how the criticisms from the Financial Time were anywhere beyond the obvious ideological.  I was thus pleased to read Francis Diebold’s blog on this craze. And to see the repeated acknowledgements that Piketty’s data being made public was a great thing. Although somewhat dismayed that such a painstakenly gathered dataset was not submitted to a more advanced econometric/statistical processing than the one offered by Excel… Definitely looking forward a more [statistically] involved analysis  of the data. (Unsurprisingly, Nassim Taleb reanalysed the whole craze as missing the fat tail features of wealth accumulation. With new aphorisms like “the fastest road to bankruptcy in foreign exchange was an economics degree”.)

hospital series

Vatnajøkull blir brukt for scener som foregår nord for The Wall.

While I usually never find enough time to watch series (or even less telly!), I took advantage of those three weeks at the hospital to catch up with Game of Thrones and discovered Sherlock, thanks to Judith. As I have been reading George Martin’s epics, A Song of Ice and Fire, from the very beginning in 1991, I was of course interested to see how those massive books with their intricate politics and complex family trees could be made into 50 minutes episodes. Glimpses caught from my son’s computer had had me looking forward to it. After watching the entire second season and the earlier episodes of the third season, I am quite impressed by both the rendering of the essentials of the book and the quality of the movies. It is indeed amazing that HBO invested so much into the series, with large scale battles and medieval cities and thousands of characters. The filming locations were also well-chosen: while I thought most of the northern scenes had been shot in Scotland, it actually appears that they mostly came from Ireland and Iceland (with incredible scenery like the one above beyond the Wall!).  The cast is not completely perfect, obviously, with both Jon Snow (Kit Harington) and Rob Stark (Richard Madden) being too shallow in my opinion and Daenerys (Emilia Clarke) lacking charisma, but most characters are well-rendered and the Lannisters are terrific, Tyrion (Peter Dinklage) being the top actor in my opinion (and Arya (Maisie Williams) coming second). I was also surprised by the popularity of the series at the hospital, as several nurses and doctors started discussing it with me…

Sherlock Holmes is a British series, set in contemporary London, and transposing some of Sherlock Holmes’ adventures in contemporary Britain. While I had not heard about this series previously, I was quite taken by it. It is quite innovative both in its scenario and its filming, it does not try to stick to the books, the dialogues are witty and the variety of accents quite pleasant (if hard to catch at times), and… Watson has a blog! It is also a pleasure to catch glimpses of London (Baker Street is actually Gower Street, near UCL) and the Hound of Baskerville takes place on Dartmoor.  I do not think I will continue watching those series once out of the hospital, but they were a pleasing distraction taking me far, far away from my hospital room for a few hours!

17 equations that changed the World (#2)

(continuation of the book review)

If you placed your finger at that point, the two halves of the string would still be able to vibrate in the sin 2x pattern, but not in the sin x one. This explains the Pythagorean discovery that a string half as long produced a note one octave higher.” (p.143)

The following chapters are all about Physics: the wave equation, Fourier’s transform and the heat equation, Navier-Stokes’ equation(s), Maxwell’s equation(s)—as in  The universe in zero word—, the second law of thermodynamics, E=mc² (of course!), and Schrödinger’s equation. I won’t go so much into details for those chapters, even though they are remarkably written. For instance, the chapter on waves made me understand the notion of harmonics in a much more intuitive and lasting way than previous readings. (This chapter 8 also mentions the “English mathematician Harold Jeffreys“, while Jeffreys was primarily a geophysicist. And a Bayesian statistician with major impact on the field, his Theory of Probability arguably being the first modern Bayesian book. Interestingly, Jeffreys also was the first one to find approximations to the Schrödinger’s equation, however he is not mentioned in this later chapter.) Chapter 9 mentions the heat equation but is truly about Fourier’s transform which he uses as a tool and later became a universal technique. It also covers Lebesgue’s integration theory, wavelets, and JPEG compression. Chapter 10 on Navier-Stokes’ equation also mentions climate sciences, where it takes a (reasonable) stand. Chapter 11 on Maxwell’s equations is a short introduction to electromagnetism, with radio the obvious illustration. (Maybe not the best chapter in the book.) Continue reading

Bayesian tweet

Posted in University life with tags , , , , , , , on November 14, 2011 by xi'an

After Scott Sisson’s tweet on ABC, Richard Everitt from Oxford (England) has started a Bayesian tweet on all things Bayesian. Which made me realise Bayes 250 had made it to the BBC website!
