One of the reasons why I find the sitcom, The Big Bang Theory, as well as its spinoff, Young Sheldon, enjoyable, is the fact that they respect the science.

That is to say, the science that we see pop up in the series from time to time is, well, it may be fictitious but not bogus. Not gobbledygook.

Here’s the latest example. In the most recent Young Sheldon episode, we see Sheldon’s first paper, published in the fictitious journal, “International Physics Review”.

The journal may be fictitious, but the format is not: It’s the standard Physical Review layout, pretty much. Looks quite legit!

The title actually makes sense. The Calabi-Yau manifold is a popular mathematical tool, used to deal with, or “compactify” the unwanted excess dimensions of 10-dimensional supersymmetric string theory.

The abstract cannot be read in full, but the words that are visible are not nonsense. OK, as far as I know there is no “Vail-Walker metric compactification”, but the fragments of text that we can read actually make sense, sort of: which is to say, the words are not randomly strung together, they actually form expressions that you might encounter in entirely legitimate physics texts.

I mean, usual Hollywood would have something like this Midjourney creation on a sheet of paper or a blackboard:

Midjourney’s response to the prompt, “A gentlecat physicist in front of a blackboard discussing the Schwarzschild metric”.

I mean, Midjourney draws lovely physicist cats, but it certainly knows nothing about the Schwarzschild solution. The creators of The Big Bang Theory do: If Sheldon Cooper talks about the Schwarzschild solution, you can bet that in the background, on the blackboard you’d see something like \(ds^2=(1-2GM/r)dt^2-(1-2GM/r)^{-1}dr^2-r^2d\theta^2-r^2\sin^2\theta d\phi^2.\)

It is fashionable these days to curse our city’s transit company, but here’s some praise for a change.

I wanted to thank those employees of OC Transpo that I ran into the other day who helped me recover a lost phone. Not only was the phone located and returned to us in short order, the gentlemen I met, without a fault, were exceptionally polite, helpful, and, well, just genuinely nice! What could have been an awfully frustrating experience for us turned into something that, well, made my day.

Thank you, OC Transpo.

By the way, a large-ish city’s major bus depot is a fascinating 24/7 operation.

As of yesterday, I think we again officially qualify as a three-cat household.

Which is to say, Rigby and Raina now have moved upstairs, no longer using our basement as their “safe place”. They are still a bit apprehensive: Rigby can be petted, Raina not so much, but they made friends with Freddy, the three cats now eat together, and they found new favorite sleeping spots around the house.

They are so… elegant. Beautiful little guys. I hope they will spend many happy years with us.

Despite working with them extensively for the past 18 months or so, our “little robot” friends continue to blow me away with their capabilities.

Take this: the other day I asked Claude opus 3 to create an N-body simulation example from scratch, in HTML + JavaScript, complete with the ability to record videos.

Here’s the result, after some very minor tweaks of the code produced by Claude, code that pretty much worked “out of the box”.

The code is simple, reasonably clean and elegant, and it works. As to what I think of our little robot friends’ ability to take a brief, casual description of such an application and produce working code on demand… What can I say? There’s an expression that I’ve been overusing lately, but it still feels the most appropriate reaction: Welcome to the future.

Can someone explain, by any chance, why, when moments ago I logged out of the Canada Revenue Agency Web site after filing an HST return, I was greeted with a German-language message announcing that my logout was successful?

I mean, a French-language message, sure. Inuit, sure. Aber Deutsch? Ja, ich kann ein bisschen Deutsch sprechen, aber woher wissen sie das?

So here is the thing. When you announce to the world your latest breakthrough in quantum computing, you might want to make sure first that the results cannot be replicated using hardware that is nearly half a century old, from the heyday of 8-bit personal computers.

Granted, the paper announcing this result was presented at a joke conference, but the paper itself is no joke: It’s actually quite well-written and the results appear credible.

I admit I loved this result because not only does it provide an example supporting my skepticism of sensationalist quantum computing claims, it also involves the computer that played a significant role in my early career, and which also happens to be the first computer that I proudly owned.

Of course the real point is that sensationalist coverage aside, apart from highly specialized, niche applications in which quantum computers basically play the role of specialized analog computers, the “quantum revolution” will not happen without scalable quantum computing, and scalable quantum computing will not happen without beating the threshold theorem. I am one of the skeptics: I strongly suspect that the threshold theorem will be shown to be a “no go” theorem. It is, of course, entirely possible that I am wrong about this, but in my mind, quantum computing is in the same league as fusion power: a technology that forever remains “just around the corner”.

I just finished watching the first (but hopefully not the only) season of the new Amazon Prime series, Fallout.

There have been three modern game franchises that I became quite fond of over the years, all of the post-apocalyptic genre: S.T.A.L.K.E.R., Metro, and Fallout. Metro has incredible storytelling: For instance, meeting the last surviving theater critic or the shadow artist at the half-flooded Bolshoi station of the Moscow Metro are moments I’ll never forget. And the S.T.A.L.K.E.R. series has its own incredible moments, foremost among them when I finished the main storyline of the third installment, Call of Pripyat, by accident in the middle of the night, in-game time, and found myself alone, in the dead silence, near the center of a deserted, pitch dark Pripyat, with my comrades gone. The relief I felt when I retreated to the Laundromat and found that it was now full of lively stalkers like myself, eating, listening to music, sleeping… A reaffirmation of life in that dead city.

And then FalloutFallout is in a league of its own. I admit I only played the 3D open world installments of the franchise, starting with Fallout 3. A game that begins with The Ink Spots singing how they don’t want to put the world on fire… with the burned-out, post-nuclear ruins of the DC Mall serving as background scenery. A game in which, after “growing up” inside an underground Vault, you experience true daylight for the very first time, with eyes that never saw anything other than artificial lighting.

So it is this Fallout universe that was turned into a television series on Amazon Prime, and what a series it is. It captures the vibe of the game franchise perfectly, but it also stands on its own as a darn good television series.

The first five minutes of the first episode already contain an instant classic: The line uttered by a little girl as she, horrified, is looking at the growing mushroom cloud enveloping Los Angeles, trying to measure it by holding out her thumb, as taught by her dad. “Is it your thumb or mine?” she asks innocently.

But the real motto of the series is a statement made by one of the main protagonists, Maximus, in episode five. “Everybody wants to save the world,” Maximus observes, “they just disagree on how.”

Doesn’t that perfectly capture our present-day world of 2024, too, as we are slowly, but inevitably, stumbling towards a new “chaotic era” (to borrow an expression from another recent television adaptation, the 3 Body Problem)? I can only hope that we don’t all end up like Shady Sands, the one-time capital city of the New California Republic, pictured above. Because, as all Fallout players know, war… war never changes.

Igitur qui desiderat pacem, praeparet bellum — Publius Flavius Vegetius Renatus in De Re Militari (~400 AD)

The West is full of useful idiots*.

This is nothing new. This was true in the 1920s and the 1930s, with countless Western intellectuals and other activists apologizing, expressing support, even admiration for Lenin, later Stalin, Mussolini and Hitler.

In the 1950s and the 1960s, this continued: Useful idiots proclaimed the West as militarist, imperialist, or worse; the USSR and the Soviet Bloc were presented as a huggable, benign alternative to the evils of capitalism.

And it continues to this day. Ever since the start of the Ukraine war on February 24, 2022 (or, depending on how one is counting, back in 2014 with the occupation of the Crimea and Donbass), “reasonable” Western voices (often amplified, overtly or covertly, by a well-financed Russian propaganda machine) have been advocating negotiation. Peace. Ukraine must accept the inevitable.

Then, on October 7, 2023, Hamas launched a brutal attack on Israel. I won’t go into the prehistory of Palestine. The narrative is long, and depending on where one begins the history, any viewpoint can be justified with a clever twist of the facts. Let’s just say that since 2005, Gaza has been a self-governed territory. Yes, the constraints imposed by Israel were heavy, though Israel (and Egypt!) certainly had their reasons. Anyhow, the point is, none of that, absolutely none of that, justified that attack on October 7, which involved the murder of nearly 700 civilians and the kidnapping of around 250 civilian hostages. An attack that had no military objectives whatsoever, but was designed to impose as much pain on innocent civilians as possible. In other words, a textbook case of a massive terror attack.

I don’t know why anyone in his right mind thinks that a state like Israel would not react to such an attack with a devastating military response, aimed at decapitating, destroying Hamas, even if it entails significant “collateral damage”, which is to say, a large number of civilian injuries and deaths. If I may be brutal about it, that’s what fucking war is like, people. You know how many civilians were killed, for instance, when the Soviet army liberated the city of my birth, Budapest, in 1945? Or how many civilians were killed in places like Dresden or Tokyo, not to mention Hiroshima and Nagasaki? And of course it doesn’t take a lot to figure out that this was very much in line with the expectations of Hamas and their Iranian backers: They counted on an Israeli response, in the hope that it interrupts the process of warming relations between Israel and its Arab neighbors, turns international opinion against Israel, perhaps even undermines American support for the Jewish state, and thus strengthens the position of the Islamic Republic of Iran in the region.

Oh no, in come the useful idiots. “Genocide,” they scream, every time some incident or statistic, often grossly inflated by the Hamas propaganda machine, sees the light of day. Where were you on October 7? All I heard was deafening silence. And where were you in the past two years when Putin systematically attacked civilian targets in Ukraine, his troops (military units often made up of pardoned convicts) murdering civilians wholesale, kidnapping and indoctrinating Ukrainian children? Silent, it seems, except for those among you who were already blaming the West because, you know, NATO or whatever.

Perhaps, if I really want to be charitable about this, it’s simply that they hold the West, they hold Israel, to a higher standard. When Putin targets civilians in Ukraine, when rampaging Hamas militants murder civilians wholesale, there are no sounds of protest because this is how these regimes are expected to behave. When Israel targets an aid convoy or when an Israeli airstrike kills civilians, the protests are loud and clear because the expectation is that they will do everything to protect civilians even if it means fighting with one hand tied behind their backs. I don’t know, but I find the hypocrisy deplorable.

Speaking of NATO, they must be the ineptest organization in human history. I mean, Soviet, and now Russian, propaganda tells us that the sole purpose of NATO is to harm and destroy Russia. Yet in the now 75 years of NATO’s existence, the organization has not managed to launch a single military attack on Russia! What stellar incompetence!

Anyhow, I understand that many of the useful idiots are driven by the purest of intentions. They don’t want to see innocents die. They want to live in a peaceful world.

Well, guess what? So do I. I am no less appalled by civilian deaths in Gaza than in Kharkiv, though I do see a bit of a difference between a military (Russia’s) that purposefully targets civilians vs. a military (Israel’s) that tries, at least half-heartedly, to reduce civilian casualties. And I am not exactly a diehard supporter of that corrupt crook, Netanyahu, who is clinging to power because who knows that once he leaves office, he may very well end up facing criminal prosecution for bribery, fraud, and breach of trust.

But unlike the useful idiots, I also remember my history lessons.

Let’s just go back in history less than 90 years, to the years preceding the last global conflict.

In 1936, Adolf Hitler launched his biggest gamble yet: The remilitarization of the Rhineland. Through this step, he risked open conflict with the West, since it was a direct violation of the Versailles peace treaty. His Wehrmacht was under strict orders to retreat if they ran into any significant military resistance.

But they didn’t. The West didn’t want war. Democracies are like that: Contrary to conspiracy theories, war is not good for business, and people prefer good food and great sex over being used as cannon fodder or turned into minced meat by carpet bombings, so they vote for the doves, mostly. But the doves are not always right. When it comes to regimes like Hitler’s, a desire for peace is seen as a sign of weakness, an opportunity waiting to be exploited. Churchill knew this, but he was ostracized as a warmonger.

Then came 1938. Neville Chamberlain returned from Munich, triumphant. “Peace for our times,” he proclaimed, as he stepped off his airplane on September 30 that year, having just signed a treaty with Hitler’s Germany. The Munich Agreement, as it was called, obliged Czechoslovakia (who were not even invited to the conference) to cede their border regions, the Sudetenland, to Germany. The inevitable result followed: Within a few months, a German puppet regime in Slovakia declared its independence, and the rest of Czechia was then invaded by Germany, and turned into a “protectorate”. And then, of course, on September 1, 1939 — just 11 months after Chamberlain returned with “peace for our times” — a World War began in earnest, with Germany’s attack on Poland and the resulting declaration of war on Germany by Western powers.

Is this what you want? Another world war? Then support peace initiatives that demand Ukraine to lay down their arms. Support Hamas by spreading their propaganda about “genocide”. You may even achieve limited goals. You will have the peace and quiet of a graveyard in Ukraine. Hamas may “peacefully” return to Gaza to rebuild its terror infrastructure.

But the message that Hamas or Putin or Xi or Kim or the ayatollahs will see is different. It’s a message of weakness. It’s a message of encouragement, that they can continue doing whatever it is that they are doing, always able to count on help from the West’s “useful idiots”. And trust me on this: If history is any guide, the resulting conflict will be far greater, far more genocidal than your worst fears, and chances are neither you nor I will survive to see its conclusion, along with a large portion of humanity.

I admit I am terrified. This shitshow is going to get a lot worse before it gets better. Innocent people will die in large numbers, often at the hands of those that we do, and must, hold to higher standards. But I also worry that thanks to our well-meaning but fatally nearsighted useful idiots and the policies of appeasement they pursue, a lot more death and suffering will follow.

The quickest way of ending a war is to lose it, and if one finds the prospect of a long war intolerable,
it is natural to disbelieve in the possibility of victory
— George Orwell, in Second Thoughts on James Burnham (1946)


*A useful idiot is a person who unwittingly supports a cause or political agenda without fully comprehending its goals, and is cynically manipulated or exploited by those in power to advance their objectives. The term is often attributed to Vladimir Lenin, who allegedly used it to describe Western intellectuals who naively supported the Soviet Union, though its documented uses in the British press predate the establishment of the USSR by many decades.

Hello, world, please meet Rigby and Raina.

Rigby and Raina are two cats from Arnprior, who now live in our home. They are still more than a little apprehensive, but at least they no longer feel compelled to always hide when we enter the basement, where they presently live. I hope that soon enough, they’ll be willing to venture forth and explore the house.

A house that might be full of dangerous wildlife! Like this one:

OK, don’t worry, it’s not a lion in a flimsy wooden cage. Just our cat Freddy. Nor is he in any sort of distress. He’s just looking at my wife through the kitchen patio door, meowing at her through the glass.

We have yet to see how Rigby and Raina will get along with Freddy, but we’ve been assured that they are okay with other cats and indeed, I’ve seen it at the shelter where they came from that they seemed comfortable in a room shared with several other cats.

So yes, we are again a three-cat household. Or will be, as soon as these two gray beauties find the courage to come forth and start exploring.

People, including responsible scholars and journalists, have begun to wonder publicly about the possibility that with conflicts (Ukraine, the Middle East, perhaps China-Taiwan) spiraling out of control, perhaps this will lead the world to another devastating World War. (We’ve had global peace for far too long, I guess.)

I suspect future historians will frame it differently. They will know that it’s a world war. They will simply debate if its beginning should be marked by Russia’s invasion of the Crimean peninsula and the Donbass region (February 2014); Russia’s full-scale invasion attempt (February 24, 2022); the Hamas attack on Israel (October 7, 2023); or some other event.

But that’s like debating if WW2 really began with, say, the Spanish Civil War (1936), the Marco Polo Bridge incident in Beijing (July 7, 1937) that marked the start of the Japanese occupation of parts of China, the Anschluss (March 12, 1938), the Sudetenland occupation (October 1, 1938) or Germany’s full-scale attack on Poland on September 1, 1939.

The thing is, people in 1939 did not yet know that it was a “world war”. Eventually, they found out of course. Kind of hard not to, when the world around you lies in ruins.
