I just discovered a new Canadian television series: Continuum, on the Showcase channel.

The premise: a group of terrorists (or freedom fighters, depending on one’s point of view) in a corporatist, dystopian future escape execution by traveling 65 years back in time, to 2012. Along with them, a female police officer also ends up in present-day Vancouver.

Back in the old days, discovering something like this mid-season would have been a disappointing experience: not knowing the back story, I might have lost interest. But these are not the old days anymore; all the episodes of Continuum that aired to date can be viewed on Showcase’s Web site.

And they are worth watching. It’s a remarkably good series, and so far, after seven episodes, the quality has not slipped yet. Likable characters, believable effects, and a thought-provoking story. Only three episodes remain from its first season… I hope it gets the green light for a second. Series like this tend to die prematurely even in bigger markets. But then, some of them survive, even in Canada.

Sometimes one comes across Internet gems just as they are about to disappear.

Just south of Budapest, near the expressway that leads to Lake Balaton, there is a small village by the name of Tordas.

Tordas has had a small community radio station for the past 12 years. For the first decade, it was a pirate station, broadcasting without a license, but as of 2010, they are officially licensed to operate their 1 W (!) transmitter.

Alas, not for much longer. They are about to go silent this weekend, buried by bureaucratic requirements imposed by Hungary’s new media authority.

I read about this today and tuned into Radio Tordas over the Internet. I was in for a treat.

For instance, I heard a version of The Beatles’ Yellow Submarine, sung in Latin (!) by the late British MP Derek Enright.

I heard a cover of These Boots Are Made for Walkin’, sung by songwriter Lee Hazlewood, with alternate lyrics that end with the words, “this is the part of the record where the engineer Eddy Brackett said if we don’t fade this thing out, we’re all gonna be arrested”.

I heard an wonderful song, Guns of Brixton, by the French band Nouvelle Vague.

I heard a rather unusual and humorous cover (mostly vocals and acoustic instruments) of Jean Michel Jarre’s electronic composition Oxygen, by the Hungarian band Zuboly.

I heard an amazing cover of The Rolling Stones’ Play With Fire. I have no idea who was singing, which is a pity, because he almost sounded like Tom Waits. (No, I don’t think it was Tom Waits.)

I heard many other things, including two rather unusual children’s tales from the immortal Ervin Lazar, known in Hungary for, well, his rather unusual children’s tales.

And this radio station is about to go off the air for good. Perhaps they’ll survive on the Internet. If so, they’re on my list of stations worth listening to.

I was watching CNN this morning. At around 10:08 AM, they announced that the United States Supreme Court struck down the key “individual mandate” provision of Obama’s health care reform law.

A few minutes later, it dawned on them that the justices’ comments relating to the Commerce Clause were not the end of the story. They still weren’t sure of themselves but they corrected the headline.

Finally, after an additional several minutes, it became clear: the law has been upheld.

I am sure I will hear more about this “save” on CNN’s Reliable Sources this Sunday…

One of Hungary’s greatest poets in the 20th century was Miklós Radnóti. As a Jew, he was conscripted into a forced labor batallion during WW2. He was tragically murdered in late 1944.

Three years prior to his untimely death, Radnóti wrote the following entry in his diary about the then celebrated Transylvanian author József Nyirő:

“The Third Reich once again organized the Weimar Poetry Day on October 31 this year, with participants that included invited poets from eleven Central and Eastern European nations. Hungarian literature was represented on Poetry Day by the Transylvanian author József Nyirő. Nyirő told the UFA, among other things, that: ‘In these days, Europe is experiencing a cultural rebirth. I am glad, literature in Hungary is glad that it can participate in this cultural rebuilding. I just saw a beautiful picture in church a short while ago, in which Luther points at the Bible passage that speaks about us being cleansed by blood. Blood cleanses Europe. The peoples of Europe, united under the sign of peace, spirituality, and the new culture, find one another. With all our hearts, all our souls we wish to take part in this joint enterprise. Long live Adolf Hitler! Long live Germany! Long live the society of German authors!’

“Now, as I copy this news item (Monday morning, November 3) I am left wondering… Is it an accident that I don’t have a single line from him on my shelf? Not even in an antology…”

The sad part? Nyirő is again celebrated in Hungary. As a matter of fact, the mayor of the Csepel district of Budapest is organizing a literary evening tomorrow night, dedicated to the writings of Nyirő. To be held… wait for it… in the Miklós Radnóti cultural center.

I can only think of one word to describe this: Disgusting.

The fun never ends. Here are a few recent screen captures from CBC Newsworld, illustrating how originally widescreen material is letterboxed to a standard definition frame, which is then letterboxed into a widescreen frame, which is then letterboxed into a standard definition frame, which then appears on a widescreen monitor… welcome to the era of postage stamp television images. My favorite is the second one, the screen shot from Prometheus… for some inexplicable reason, they actually further compressed vertically (or stretched horizontally?) an already widescreen image.



Of course marketers knew what they were doing. They knew that most people cannot tell the difference between a resolution of, say, 640×480 vs. 1024×768. So they changed the aspect ratio. And of course they aren’t describing the result as being reduced in height, stunted perhaps; they tell you that it is wider. Wider is good, right?

The author of the Martian Chronicles, Fahrenheit 451 and many other classics is no more; Ray Bradbury died today at the age of 91. Maybe one day his ashes will be taken to Mars, where they really belong.

As part of the Queen’s diamond jubilee celebrations, the British did something that hasn’t been done in 350 years: a 1000-boat pageant on the river Thames.

Being the loyalist royalist, I was watching (parts of) it on television. As I did so, I couldn’t help noticing just how soaking wet the choir was on top of the boat carrying the London Philharmonic.

Their spirit was undaunted, though, and they sang beautifully and professionally. I hope none of them caught pneumonia.

A few days ago, a bright 16-year old German student of Indian descent, Shouryya Ray of Dresden, won second prize in a national science competition with an essay entitled “Analytische Lösung von zwei ungelösten fundamentalen Partikeldynamikproblemen” (Analytic solution of two unsolved fundamental particle dynamics problems).

This story should have ended there. And perhaps it would have, were it not for the words in the abstract that said, among other things: “Das zugrundeliegende Kraftgesetz wurde bereits von Newton (17. Jhd.) entdeckt. […] Diese Arbeit setzt sich also die analytische Lösung dieser bisher nur näherungsweise oder numerisch gelösten Probleme zum Ziele.” (The underlying power law was discovered by Newton (17th century). The goal of this work is then the analytic solution of these until now only approximately or numerically solved problems.)

This was more than enough for sensation-seeking science journalists. The story was picked up first by Die Welt with the title “Mit 16 ein Genie: Shouryya Ray löste ein jahrhundertealtes mathematisches Problem” (Genius at 16: Shouryya Ray solves centuries-old mathametical problem) and then translated into English and other languages, even appearing in the Ottawa Citizen. In short order, even a biographical entry on Wikipedia was created; now nominated for deletion, many are voting to keep it because in their view, the press coverage is sufficient to establish encyclopedic notability.

Cooler heads should have prevailed. What science journalists neglected to ask is why, if this is such a breakthrough, the youth only received second prize. And in any case, what on Earth did he actually do? His essay or details about it were not published. The only clue to go by was a press photo in which the student holds up a large sheet of paper containing an equation:

As I discussed this very topic on a page I placed on my Web site a few years back (reacting to some bad math and flawed physics reasoning in an episode of the Mythbusters) I felt compelled to find out more. I guessed (correctly, as it turns out) that \(u\) and \(v\) must be the horizontal and vertical (or vertical and horizontal?) components of the projectile’s velocity, \(g\) is the gravitational constant, and \(\alpha\) is the coefficient of air resistance. However, I am embarrassed to admit that although I spent some time trying, I was not able to find a way to separate the variables and integrate the relevant differential equations to obtain Ray’s formula. I was ready to give up actually when I came across a derivation on reddit (and I realized that I was on the right track all along, I was just stubbornly trying to do a slightly different trick, which didn’t work). The formula is correct, and it is certainly an impressive result for a 16-year old, worthy of a second prize.

But no more. This is not a breakthrough. As it turns out, similar implicit solutions were well known in the 19th century. A formulation that differs from Ray’s only in notational details appeared in a paper by Parker (Am. J. Phys, 45, 7, 606, July 1977). Alas, such an implicit form is of limited utility; one still requires numerical methods to actually solve the equation.

Much of this was probably known to the judges of the competition, which is probably why they awarded the student second prize.

Hopefully none of this will deter young Mr. Ray from pursuing a successful career as a physicist or mathematician.

The Dragon capsule of SpaceX Corporation is on its way after a successful launch towards the International Space Station. If all goes well, it will dock with the ISS in two days’ time, making it the first commercial spacecraft to do so, and paving the way to eventual human flight to the ISS on board commercial vehicles. This really is the beginning of a new era.

And the end of an old one. The ashes of James Doohan, better known as Scotty to Star Trek fans, are reportedly on board the Dragon capsule, to fulfil the actor’s final wishes.

“This is it. The Big Bang Theory television show lost all its credibility for me. I could put up with the laugh track (though I cannot understand why they need a laugh track for a realistic drama series) but not with this utter contempt towards elementary logic. Here is what happened: in one episode (S1E15), Dr. Sheldon Cooper tells us that Missy is his fraternal twin sister. But then, in another episode (S3E17), Dr. Cooper purportedly says, “I have a twin sister whose assaults began in utero. If only I’d had the presence of mind to reabsorb her then I’d have a mole with hair on it”. But a real-life Dr. Sheldon Cooper would never make such a mistake: he would know very well that one can only reabsorb an identical twin. This blatant disregard for logic is an insult to the viewers’ intelligence. I am sorry, but this show is unwatchable. Change the channel, please.”

The preceding rant is best delivered, of course, in the voice of Dr. Sheldon Cooper. Fortunately, I am not Sheldon Cooper, and I will still enjoy TBBT when it returns for its next season in the fall. Nor do I have any plans of joining the ranks of nitpickers who demonstrate their presumed intellectual superiority by spending hours watching and re-watching television shows and movies just to find the odd goof. I swear I only noticed this one by accident!

I am reading about plans to introduce commercials on CBC Radio 2. Looks like a done deal unless the CRTC disagrees, which I think is unlikely.

What has been done to CBC Radio in the past 25 years is just unconscionable. They are turning a once world-class national broadcaster into a run-of-the-mill radio network that is more and more indistinguishable from its commercial counterparts.

Meanwhile, here in Ottawa, the capital of Canada, for much of the day there are no radio stations broadcasting anything that could be described as “high culture”. None. No classical music, no jazz, no arts programs, no literary programs, just commercial music, talk radio and the like.

Oh well. Thanks to the Internet, we can always listen to the BBC. Or ABC from Australia. Or Bartok Radio from Budapest. Or other national broadcasters from countries much smaller and much poorer than Canada who nevertheless believe that investing in high culture is not worthless elitism but an investment in the future.

Last night, I was watching a documentary about the 1943 Nazi film Titanic, an attempt by Göbbels to twist the tragic story of the sinking for German propaganda purposes (Briefly: Titanic sank because of the greed and hubris of British capitalists and despite the heroic efforts of a German first officer.)

The story behind the movie is fascinating (director was arrested by the Gestapo and hanged himself, film was banned by Göbbels and only shown in occupied territories, never in Nazi Germany), but then they screw it all up with a complete fabrication. The ship that was used for the filming, the luxury ocean liner SS Cap Arcona, was herself sunk in May 1945 with about 5,000 concentration camp prisoners on board. The sinking happened in part because of a shake-up of responsibilities between Bomber Command and Fighter Command in the RAF, in the wake of the firebombing of Dresden. But according to the film I just saw, the sinking was deliberately planned by the Nazis who filled the ship with flammable fuel and intentionally put it out for the RAF to bomb. This is just a boldfaced lie (it’s not like the Germans had any fuel reserves left in April 1945, and they certainly didn’t need to resort to such an elaborate plot to end the lives of a mere 5,000 people; besides, several ships were hit that day, including an unmarked German hospital ship) and I keep wondering why, nearly 70 years after the end of World War 2, we are still being subjected to wartime propaganda.

Incidentally, the Web page I linked to above states that the sinking of the Cap Arcona was the world’s greatest ship disaster. Not so. That sad distinction belongs to the MV Wilhelm Gustloff, another German ship that was torpedoed by the Soviets in January 1945 while carrying over 10,000 evacuees, mostly civilians. More than 9,000 people died.

And while I was debating with myself whether or not to turn this into a blog post, I was listening to the noon newscast on CTV Ottawa. In the context of a sexual attack this morning on Metcalfe street, the reporter told us that “in a single day, nearly 5,300 cases of sexual assault are reported in Canada”. What? That is a humongous number. It is also wrong. What actually happened in a single day (April 19, 2006) was that nearly 5,300 victims of sexual assault and other violent offences requested assistance from victim service agencies across Canada. The number of “incidents involving sexual offences” was 27,094 in 2002; that translates into about 75 sexual assaults in a single day. Not 5,300.

To paraphrase Mark Twain, there are lies; there is history; and then there are statistics.

But perhaps “damn lies” is just a synonym for history?

At the very end of tonight’s episode of The Simpsons, just before the end credits, we caught a brief glimpse of Pioneer 10 (or was it 11?), along with an extraterrestrial intently studying Carl Sagan’s famous golden plaque.

But wait a minute… stupid alien is holding the plaque upside-down. No wonder he can’t make sense of it.

And they didn’t get the shape of the RTG fins right. Can’t really blame them; way too many artistic depictions of Pioneer show the generators with the small, rectangular fins that, I believe, were on (non-nuclear) engineering mockups used during testing.

I was reading about a place called Göbekli Tepe today.

This is a place in southeastern Turkey. It is the site of an archeological excavation; they are exploring the ruins of an old temple.

The ruins of a really old temple. Really, really, really old.

How old? Well… when the first Egyptian pyramid was still on the drawing board, Göbekli Tepe was already some 6,000 years of age. Indeed, when Göbekli Tepe was built, the place where I now live, Ottawa, was still covered by the Champlain Sea. The oldest ruins at Göbekli Tepe are 11,500 years old, take or leave a few centuries.

That is an astonishing age for a major stone structure like this. Wikipedia tells me that it was built by hunter-gatherers, but I have a hard time accepting that hypothesis: Stone construction on this scale requires highly specialized skills not to mention the organization of the necessary labor force. Maybe I lack imagination but I just can’t see how hunter-gatherer tribes, even if they have permanent village settlements, would be able to accomplish something on this scale.

But if it wasn’t hunter-gatherers, who were they? What kind of civilization existed in that part of the world 11,500 years ago that we know nothing about?

I have no delusions about my abilities as a graphic artist, but hey, it’s from the heart. Happy Easter, everyone!

As to why we choose to celebrate the gruesome death on the cross and subsequent resurrection of a young man some 2,000 years ago, one whose sole crime was that he was preaching love and understanding among neighbors, with bunny rabbits laying gaudy-colored eggs and such nonsense, I have no idea. But then, I am just the clueless atheist here, so what do I know?

I only wish more people actually listened to that young man’s message, instead of choosing hatred and violence. The world would indeed be a better place.

I am holding in my hands an amazing book. It is a big and heavy tome, coffee table book sized, with over 600 lavishly illustrated pages. And it took more than 30 years for this book to appear finally in English, but the wait, I think, was well worth it.

The name of Charles Simonyi, Microsoft billionaire and space tourist, is fairly well known. What is perhaps less well-known in the English speaking world is that his father, Karoly Simonyi, was a highly respected professor of physics at the Technical University of Budapest… that is, until he was deprived of his livelihood by a communist regime that considered him ideologically unfit for a teaching position.

Undeterred, Simonyi then spent the next several years completing his magnum opus, A Cultural History of Physics, which was eventually published in 1978.

Simonyi was both a scientist and a humanist. In his remarkable, unique book, history and science march hand in hand from humble beginnings in Egypt, through the golden era of the classical world, through the not so dark Dark Ages, on to the scientific revolution that began in the 1600s and culminated in the discoveries of Lagrangian mechanics, thermodynamics, statistical physics, electromagnetism and, ultimately, relativity theory and quantum physics.

And when I say lavishly illustrated, I mean it. Illustrations that include diagrams, portraits, facsimile pages from original publications decorate nearly every single page of Simonyi’s tome. Yet it is fundamentally a book about physics: the wonderfully written narrative is well complemented by equations that translate ideas into the precise language of mathematics.

I once read this book, my wife’s well worn copy, from cover to cover, back in the mid 1990s. I feel that it played a very significant role in helping me turn back towards physics.

Simonyi’s book has seen several editions in the original Hungarian, and it was also translated into German, but until now, no English-language translation was available. This is perhaps not surprising: it must be a very expensive book to produce, and despite its quality, the large number of equations must surely be a deterrent to many a prospective buyer. But now, CRC Press finally managed to make an English-language version available.

(Oh yes, CRC Press. I hated them for so many years, after they sued Wolfram and had Mathworld taken off-line. I still think that was a disgusting thing for them to do. I hope they spent enough on lawyers and lost enough sales due to disgusted customers to turn their legal victory a Pyrrhic one. But that was more than a decade ago. Let bygones be bygones… besides, I really don’t like Wolfram these days that much anyway, software activation and all.)

Charles Simonyi played a major role in making this edition happen. I guess he may also have spent some of his own money. And while I am sure he can afford a loss, I hope the book does well… it deserves to be successful.

For some reason, the book was harder to obtain in Canada than usual. It is not available on amazon.ca; indeed, I pre-ordered the book last fall, but a few weeks ago, Amazon notified me that they are unable to deliver this item. Fortunately, CRC Press delivers in Canada, and the shipping is free, just like with Amazon. The book seems to be available and in stock on the US amazon.com Web site.

And it’s not a pricey one: at less than 60 dollars, it is quite cheap, actually. I think it’s well worth every penny. My only disappointment is that my copy was printed in India. I guess that’s one way to shave a few bucks off the production cost, but I would have paid more happily for a copy printed in the US or Canada.

I have been exchanging e-mails with a friend. We discussed, among other things, Rush Limbaugh’s now infamous comments on Sandra Fluke.

In response to comparisons of Limbaugh to some of the vile comments made by left-wing personalities like Bill Maher in the past (who called, for instance, Sarah Palin a ‘cunt’), I said this:

“I also note that Limbaugh’s rant went way beyond the use of an offensive word: he discussed Susan [sic!] Fluke’s sexual habits repeatedly and in detail, and once he was done demonstrating his complete ignorance on the topic of birth-control drugs (no, the amount of birth control pills consumed is not related to the amount of sex a person has, he must have confused it with the pills he takes for sex; and no, Fluke was not discussing recreational use of birth control pills but specifically their widespread use to treat serious gynecological conditions) he actually asked her publicly to make a porn video of her sexual activities. And, unlike the liberal comedians mentioned (who are, after all, comedians) Limbaugh did this in all seriousness. If I had been in Fluke’s place, I’d have called Limbaugh a lecherous, drug-addled dirty old pig. Fluke was more of a lady than I am a gentleman, I guess.”

And then I realized that I should not be ashamed of my words. Instead of saying what I should do in Fluke’s place, let me just do it, plain and simple:

In my opinion, Limbaugh is a lecherous, drug-addled dirty old pig.
