Funny how “God” worked it out for the octopus but not humans. Huh.

China tried to punish Japan by telling its citizens to stop visiting. The data just exposed how badly that backfired. This is Japan's official tourism spending data for Q1 2026. China's tourism revenue collapsed 50.4% after Beijing actively discouraged its citizens from visiting Japan, following Japanese Prime Minister Sanae Takaichi's remarks defending Taiwan. Chinese arrivals cratered 60.7% in January alone and 55.9% in March. Here's what Beijing didn't count on. Taiwan, a self-governing island of 23 million people that the CCP claims as its own territory, brought in more tourism revenue to Japan than all of mainland China's 1.4 billion people. Taiwan posted +22.5% growth. Vietnam surged 71.3%. Germany jumped 59.6%. Spain up 64%. Japan still set February 2026 tourism records while China's boycott was in full effect. Japan's own Transport Minister said the drop in Chinese visitors was "not something to worry about." He was right. Beijing has used tourism as economic coercion before, against South Korea in 2017, against Japan in 2012. Every time, the targeted country adapts. Every time, Beijing overestimates its own leverage. China weaponized its tourists. Japan replaced them before Beijing finished the threat. #Japan #China #CCP #Tourism #Taiwan #Geopolitics #JapanTravel #BoycottBackfire #Asia #EconomicCoercion

大気圏再突入、「摩擦熱」「断熱圧縮」問題、結論から言うね。 👉それ、めっちゃ「空力加熱」。でもほとんど「断熱圧縮」 月軌道から宇宙船が再突入すると時速40,000km、マッハ32とかいうイカれたスピードになるけど、衝撃波面を通過した途端、流れの速度はマッハ0.2程度まで急減速される 当然この減速は大量のエネルギーを消費して、高熱やらプラズマやらが生じる この過程は「外部との熱交換がない圧縮過程」という意味では「断熱圧縮」と呼べるけれど、実際の衝撃波面では 「冷たいマッハ32の流れ」が、「衝撃波面後方にある超高温でマッハ0.2の流れ」へと叩きつけられながら一瞬で変化するというヤバいことが起きていて、この変化は不可逆的 だから、これを断熱圧縮と呼ぶのは教科書的な「可逆断熱圧縮」が想起されるため不適切、という指摘は正しい この誤解を避けるために宇宙工学では「衝撃波圧縮」という言葉を用いるし、断熱圧縮と呼びたいなら「不可逆断熱圧縮」と呼んだ方が正確 で、宇宙船目線ではこの衝撃波圧縮による加熱が95%程度を占めます 宇宙船の底面と生じる「摩擦熱」はたった5%程度 なぜかというと、「マッハ32の流れが衝撃波面を通過した途端、マッハ0.2まで減速」済みだから 底面外周部に向けて再加速されるものの、せいぜいマッハ2程度 だから生じる熱は衝撃波圧縮と比べると大したことないんですね


ワイがなぜ仕事中に「絶対に不機嫌にならない」と決めているかというと、不機嫌な人が1人でもいると、そのチームの生産性が激減するから。 不機嫌な人には相談し辛いから、聞けば5分で終わることを自力でやって2時間かかったり、「不機嫌な理由は自分のせいかも...」と思わせて生産性を下げたりする。

Because we get asked a lot. The Technological Republic, in brief. 1. Silicon Valley owes a moral debt to the country that made its rise possible. The engineering elite of Silicon Valley has an affirmative obligation to participate in the defense of the nation. 2. We must rebel against the tyranny of the apps. Is the iPhone our greatest creative if not crowning achievement as a civilization? The object has changed our lives, but it may also now be limiting and constraining our sense of the possible. 3. Free email is not enough. The decadence of a culture or civilization, and indeed its ruling class, will be forgiven only if that culture is capable of delivering economic growth and security for the public. 4. The limits of soft power, of soaring rhetoric alone, have been exposed. The ability of free and democratic societies to prevail requires something more than moral appeal. It requires hard power, and hard power in this century will be built on software. 5. The question is not whether A.I. weapons will be built; it is who will build them and for what purpose. Our adversaries will not pause to indulge in theatrical debates about the merits of developing technologies with critical military and national security applications. They will proceed. 6. National service should be a universal duty. We should, as a society, seriously consider moving away from an all-volunteer force and only fight the next war if everyone shares in the risk and the cost. 7. If a U.S. Marine asks for a better rifle, we should build it; and the same goes for software. We should as a country be capable of continuing a debate about the appropriateness of military action abroad while remaining unflinching in our commitment to those we have asked to step into harm’s way. 8. Public servants need not be our priests. Any business that compensated its employees in the way that the federal government compensates public servants would struggle to survive. 9. We should show far more grace towards those who have subjected themselves to public life. The eradication of any space for forgiveness—a jettisoning of any tolerance for the complexities and contradictions of the human psyche—may leave us with a cast of characters at the helm we will grow to regret. 10. The psychologization of modern politics is leading us astray. Those who look to the political arena to nourish their soul and sense of self, who rely too heavily on their internal life finding expression in people they may never meet, will be left disappointed. 11. Our society has grown too eager to hasten, and is often gleeful at, the demise of its enemies. The vanquishing of an opponent is a moment to pause, not rejoice. 12. The atomic age is ending. One age of deterrence, the atomic age, is ending, and a new era of deterrence built on A.I. is set to begin. 13. No other country in the history of the world has advanced progressive values more than this one. The United States is far from perfect. But it is easy to forget how much more opportunity exists in this country for those who are not hereditary elites than in any other nation on the planet. 14. American power has made possible an extraordinarily long peace. Too many have forgotten or perhaps take for granted that nearly a century of some version of peace has prevailed in the world without a great power military conflict. At least three generations — billions of people and their children and now grandchildren — have never known a world war. 15. The postwar neutering of Germany and Japan must be undone. The defanging of Germany was an overcorrection for which Europe is now paying a heavy price. A similar and highly theatrical commitment to Japanese pacifism will, if maintained, also threaten to shift the balance of power in Asia. 16. We should applaud those who attempt to build where the market has failed to act. The culture almost snickers at Musk’s interest in grand narrative, as if billionaires ought to simply stay in their lane of enriching themselves . . . . Any curiosity or genuine interest in the value of what he has created is essentially dismissed, or perhaps lurks from beneath a thinly veiled scorn. 17. Silicon Valley must play a role in addressing violent crime. Many politicians across the United States have essentially shrugged when it comes to violent crime, abandoning any serious efforts to address the problem or take on any risk with their constituencies or donors in coming up with solutions and experiments in what should be a desperate bid to save lives. 18. The ruthless exposure of the private lives of public figures drives far too much talent away from government service. The public arena—and the shallow and petty assaults against those who dare to do something other than enrich themselves—has become so unforgiving that the republic is left with a significant roster of ineffectual, empty vessels whose ambition one would forgive if there were any genuine belief structure lurking within. 19. The caution in public life that we unwittingly encourage is corrosive. Those who say nothing wrong often say nothing much at all. 20. The pervasive intolerance of religious belief in certain circles must be resisted. The elite’s intolerance of religious belief is perhaps one of the most telling signs that its political project constitutes a less open intellectual movement than many within it would claim. 21. Some cultures have produced vital advances; others remain dysfunctional and regressive. All cultures are now equal. Criticism and value judgments are forbidden. Yet this new dogma glosses over the fact that certain cultures and indeed subcultures . . . have produced wonders. Others have proven middling, and worse, regressive and harmful. 22. We must resist the shallow temptation of a vacant and hollow pluralism. We, in America and more broadly the West, have for the past half century resisted defining national cultures in the name of inclusivity. But inclusion into what?
