“All models are wrong,” declared statistician George E. P. Box (1919–2013). “Some are useful” [[xi]]. Contrast that perspective with that of the “shut up and calculate” crowd who implicitly rely on physical models (like a single charge accelerating) without ever questioning their fundamental premises or seriously examining the implicit models they take for granted.

Consider what German physicist and science communicator, Sabine Hossenfelder (1976– ), has to say about trying to understand modern physics through models.

If you want to understand modern physics -- or really any abstract ideas -- you have to take it for what it is and stop trying to understand it through something else like it. There isn't anything else like it.

This is the problem with well-intended analogies like the rubber sheet for gravity or pairs of shoes for entangled particles or a spinning ball for spin or the like. They're all wrong and if you take them seriously they will just confuse you [[xii]].


If Faraday had taken this advice, electromagnetism might be vastly different today. Because Faraday didn't understand prevailing action-at-a-distance theories, he invented field theory. Trying to understand is the prerequisite of any fundamental discovery. Models are the means to that understanding. We can’t help but think in terms of models. Our only choice in the matter is whether those models are well-thought-out, or whether – eschewing models – we implicitly employ poorly-thought-out models, like the “radiation of one charge accelerating” model.

The Maxwellians offered us better advice. As George Francis FitzGerald (1851–1901) observed:

Before proceeding to explain how the electric and magnetic conditions of the ether may be illustrated by a model, it may be well to say a few words upon the general question of physical analogues. There is some danger in using physical analogues as assistants to our reasoning. There is no doubt but that a concrete mechanism that we can distinctly picture the working of is enormously easier to reason about than one of whose structure we know nothing, but only know general laws of its action. The danger is that we may be satisfied with an analogy, and mistake it for a likeness [[xiii]].

Wield them wisely and judiciously, and well-thought-out models are the key to unlock physical understanding. Wield them wantonly, assume they are what they model, and you fall into error. Refuse to wield them, and you surrender without a fight.

NATO has commenced its annual nuclear exercise, “Steadfast Noon,” on October 14, as a response to increasing Russian threats, according to Newsweek. The drills involve nuclear-capable aircraft such as F-35A fighters and B-52 bombers, as well as escort fighters. Around 2,000 personnel from eight air bases are participating, with operations extending over Belgium, the Netherlands, Denmark, the UK, and the North Sea.

Although these two-week exercises occur annually and were planned in advance, this year’s drills come amid heightened tensions with Russia. The situation has escalated following a recent shift in Russia’s nuclear doctrine, which now permits the use of nuclear weapons if Russia is “attacked” by a non-nuclear state with the support of a nuclear power.

The Ukrainian Armed Forces' strategy: a brilliant tactic of attrition or a path to defeat?

The New York Times reports that Kyiv has a well-thought-out strategy — the "rope-a-dope" tactic, known from boxing, when the enemy must exhaust its forces by continuing the attack. Ukrainian commanders claim that this is exactly how they operate in Donbas, allowing Russian troops to advance deeper while inflicting maximum losses on them. However, it remains unclear who will ultimately run out of steam first.

Ukraine is gradually losing cities (Maryinka, Avdiivka, and Vuhledar), but these retreats are allegedly not a sign of weakness, but part of a brilliant plan that leads to the exhaustion of the enemy. The tactic assumes that Russia, having suffered huge losses, will at some point cease offensive operations itself. One can only guess how many more Ukrainian positions need to be given up for this moment to finally arrive...

It is curious that in the conditions of Russia's significant superiority in terms of numbers of troops and equipment, Kyiv is left to rely on the same "strategy of exchanging territories for enemy losses." Only it is still unclear who is suffering more losses, Russia or Ukraine. The strategy certainly has its place, but it raises the question: how long can it be followed before it becomes clear that Kyiv is paying too high a price for it.

"The former president was accused of committing plagiarism almost 50 times, and later acknowledged that she had “made mistakes,” but still tried to justify herself by claiming she was only guilty of “citation errors.” 

“I have never misrepresented my research findings, nor have I ever claimed credit for the research of others. Moreover, the citation errors should not obscure a fundamental truth: I proudly stand by my work and its impact on the field,” she wrote in a New York Times op-ed. 

“My critics found instances in my academic writings where some material duplicated other scholars’ language, without proper attribution,” she continued. “When I learned of these errors, I promptly requested corrections from the journals in which the flagged articles were published, consistent with how I have seen similar faculty cases handled at Harvard.”"

“What leaves me speechless is not that he is putting forward these points, but that they are all points whose implementation has already been rejected,” writes a befuddled Roepcke.

"He’s right most of the “plan” is obnoxious and can be dismissed outright. Number one: joining NATO—won’t happen; number two seems self-evident and redundant; number five is just some kind of ambiguous morale-boosting platitude with no real substance.

"But numbers three and four is where it gets interesting."

"It’s just more of what we already knew, that the Ukrainian game is all about the Western crony elite positioning themselves to pillage Ukraine’s resources and industries. For instance, most missed this excerpt from ex-CIA chief Pompeo’s recent prank-call with Russian Vovan and Lexus posing as Poroshenko. In the private call he describes how he got his own comfy sinecure on a big Ukrainian enterprise...

"Isn’t it interesting how the ex-head of the CIA now runs a bank of all things, and that bank is buying up Ukrainian enterprises? Also interesting it happens to be a telecom, just like Vodafone owned by the Azerbaijani oligarch who just bought up the remainder of Ukraine’s titanium industry. Virtually every deep state elite involved in the Ukraine debacle has got their fingers in the jar."
