Nautilus Magazine: We Never Know Exactly Where We’re Going in Outer Space
In the early 1960s, during the space race, neither American nor Soviet scientists really knew where planets like Mars or Venus were—especially at the accuracy and precision essential for spacecraft navigation. That may sound faintly ludicrous. They of course knew roughly where a target like Venus would be when a spacecraft got there. But “roughly” in this context might be an offset of 10,000 or 100,000 kilometers. Planetary positions, their ephemerides, rely on the calibration of their orbits to extremely high precision over time. But the only way to do that properly is to make direct measurements, just as the mariners of old would need to sail right by an island or shoreline in order to nail down its latitude and longitude. [...]
It remains to be seen whether tiny spacecraft can carry the requisite computational toolkit or sensory and steering capacity to do this. The bright stars themselves might be the best markers to exploit, together with our own sun forming a navigational beacon. Tiny pulses from miniature laser diodes could provide thrust to maneuver with, and perhaps the key is to send hundreds, even thousands, of nanocraft, each with modest AI and an ability to learn from each other and to reach their goals in space and time through massive redundancy and the sacrifice of many. But when you’re trying to catch a flying bullet—whether star or planet—with another flying bullet, things can go wrong. [...]
In sending machines to other worlds, even to other stars, we have no choice but to fully admit our inaccuracies and imprecisions, to be entirely, brutally honest about our limited grasp of what’s out there. Even the laws of nature are deductions based on wholly imperfect measurements, whether of planetary orbits and gravity, or of the properties of logic and symbolic manipulation in algebra—the latter being “measured” through human minds and the machines those minds produce. The amazing thing is how well these laws let us model and predict aspects of the physical world, a capacity that has reassured and helped us for thousands of years. We have managed to turn the problem around, and can now predict the kinds of chaos that should occur across nature, from unsettled weather conditions and unstable stock markets to, of course, planets.

The Pragati Podcast: Nuclear War, Deterrence and Peace.
Nuclear war feels unthinkable, but how much peace does nuclear deterrence guarantee? Do nuclear programmes truly deter or compel adversaries in the real world? And can we imagine a world where 20+ countries have nuclear weapons?
Vipin Narang joins Pavan Srinath on Episode 124 of The Pragati Podcast to dive into the world of nuclear weapons and strategy. He shares the evolution of our understanding of nuclear strategy from early ideas of mutually assured destruction.
The Pragati Podcast is a weekly talkshow on public policy, economics and international relations hosted by Pavan Srinath.
Vipin Narang is an Associate Professor of Political Science at MIT and a member of MIT’s Security Studies Programme. He published his first book Nuclear Strategy in the Modern Era in 2014, and is currently working on his second book, Strategies of Nuclear Proliferation, in which he explores how states pursue nuclear weapons. He is on Twitter at @NarangVipin.

New Statesman: Britain at the end of history
While the prime minister was firefighting at home, her position was deteriorating abroad. In January 1989, one of the great love affairs of modern diplomacy came to an end, as US president Ronald Reagan left the White House. His successor, George HW Bush, did not share Reagan’s affection for Thatcher, calling her a “very difficult” woman who “talks all the time when you’re in a conversation”. Bush saw West Germany, not Britain, as America’s “partner in leadership”, making it harder for Thatcher to amplify her influence through the “special relationship”.
Relations were also poor with West Germany. The federal chancellor, Helmut Kohl, thought Thatcher “ice-cold” and “dangerous”, while Thatcher herself made no secret of their “acrimonious discussions”. She got on better with the French president, François Mitterrand, who credited her with “the eyes of Caligula, and the lips of Marilyn Monroe”. Yet the two had little in common politically, and Thatcher had spent much of the summer belittling the bicentenary of the French Revolution of 1789. [...]
Over the winter of 1989-90, Thatcher gave a series of inflammatory press interviews, warning of a resurgence of German nationalism. “What is reunification all about?” she asked rhetorically. “One people, one fatherland.” She underlined references to the two World Wars in documents, and astonished George Bush and François Mitterrand by pulling out wartime maps from her handbag. Notes for one speech were scribbled on the back of a newspaper cutting on the 1938 Munich Agreement: an indication, perhaps, of what she was requesting from the archives. [...]
Powell was at the centre of one of the most damaging incidents of this period: the Chequers seminar of March 1990. Thatcher had invited a group of historians – including Gordon Craig, Hugh Trevor-Roper, Norman Stone and Timothy Garton Ash – to discuss Germany, and Powell produced a hair- raising summary of the talks. An account of the German “national character” included “angst, aggressiveness, assertiveness, bullying” and “egotism” in a veritable alphabet of insults. There were still questions to be asked as to “how a cultured and cultivated nation had allowed itself to be brainwashed into barbarism”; and the “way in which the Germans currently used their elbows… suggested that a lot had still not changed”. The document was leaked to the Independent, causing outrage in Bonn and dismay in other capitals.

UnHerd: Leon Trotsky’s disturbing afterlife
But in many ways, what is most interesting about Trotsky is not his death, or life, but his afterlife. For, to a great extent he remained (and for some people amazingly remains still) the great ‘might have been’ of the Soviet era. Never mind the people who actually grew up while the horrors of the Soviet system were ongoing, I have heard people in my own adult life, born in my own lifetime, and sometimes younger than myself (people in their twenties or thirties), seriously describe themselves as being (or at some point having been) a Trotskyist. [...]
Several reasons present themselves. One is the possibility that his undoubted intellectual ability, plus his assassination in a far-away land gave him a certain martyr-like glamour. He was working on his magnum opus about his enemy right up until the moment of his death; the combination of work ethic and premature demise can be a heady brew. Especially so for a certain type of Western intellectual who likes the idea of fanaticism for a cause precisely because they have themselves never had to suffer at the hands of such fanatics.
But the greater reason would appear to be that reason which remains perhaps the greatest bit of unfinished business of the 20th Century. The recognition that the Soviet, Communist, Marxist experiments were not trees which just happened to give off some poison fruits. Or beautiful ideas which were just mishandled and misappropriated by misguided hands. But rather that the whole dream was a nightmare from beginning to end. And always was going to be. That the Communist experiment had no more likelihood of delivering peace on earth than did the Fascist attempt to try to produce the same.

The Prospect Interview #141: How can nations atone for their sins?
Why do some countries succeed in confronting their pasts, and others fail? Authors Ivan Krastev and Leonard Benardo join the Prospect Interview this week to discuss the question of the summer: how do nations come to terms with the historical crimes they’ve committed?
Ivan and Leonard write an essay on the (unsuccessful) Russian case in this month’s issue of Prospect, in which they trace the curious recent rehabilitation of Joseph Stalin in recent years. What does it take for a country to face up to its history—and what do they make about Britain’s ongoing debate on the statue of Winston Churchill?
Freakonomics: How the Supermarket Helped America Win the Cold War (Ep. 386 Rebroadcast)
Aisle upon aisle of fresh produce, cheap meat, and sugary cereal — a delicious embodiment of free-market capitalism, right? Not quite. The supermarket was in fact the endpoint of the U.S. government’s battle for agricultural abundance against the U.S.S.R. Our farm policies were built to dominate, not necessarily to nourish — and we are still living with the consequences.

Architectuul: FOMA 38: Five Examples of Sacral Architecture in Kaunas
A choice to turn a church into a warehouse is rather interesting, since a warehouse had a symbolic meaning in the Soviet Union. Some researchers believe that converting churches into warehouses “was not the abolition of the holy but, so to speak, its replacement. The warehouse is just as ideal an order in the material world as the church is in the spiritual world. The warehouse is a materialist church, but instead of collecting people who are seeking in prayer an exalted form of the soul, it houses a multitude of objects that have found a precise inventoried form.”[2]
Nevertheless, according to various data from 1953 to 1959 nearly 15-20% of churches were closed while some of sacral buildings went through radical transformations. Vilnius Cathedral Basilica (1783) by Gucevičius was closed in 1949. During 1950 sculptures of saints, which were on the rooftop were removed and destroyed. Since the Cathedral was closed a lot of artifacts were stolen while the interior was ravaged. The Cathedral become part of the Museum of Art and was in1956 transformed into a gallery. The building was returned to the Catholic community in 1988. [...]
Kaunas Mosque also known as Vytautas the Great Mosque is one of four remaining mosques in Lithuania. Its design reminds the mosques in Northern Africa, a compact, small-volume mosque combines historical forms with oriental motifs like an elliptical dome and a small minaret, which was never used for its traditional purpose.
