His unification of electricity, magnetism and light into one coherent mathematical whole is the inspiration for subsequent attempts - some successful, some still in their rudimentary stages […]

我还以为他要说 some successful, some failed!学到了,以后做得不咋成功的项目就说还在 rudimentary stage​:blobcat3c:​我国处于并将长期处于社会主义 rudimentary stage(什么

If we no longer insist on our notions of how Nature ought to behave, but instead stand before Nature with an open and receptive mind, we find that common sense often doesn’t work. Why not? Because our notions, both hereditary and learned, of how Nature works were forged in the millions of years our ancestors were hunters and gatherers. In this case common sense is a faithless guide because no hunter-gatherer’s life ever depended on understanding time-variable electric and magnetic fields. There were no evolutionary penalties for ignorance of Maxwell’s equations.

no evolutionary penalties for ignorance of Maxwell’s equations 好好笑😆

But what are these time-varying electric and magnetic fields permeating all of space? What do E and B mean? We feel so much more comfortable with the idea of things touching and jiggling, pushing and pulling, rather than ‘fields’ magically moving objects at a distance, or mere mathematical abstractions. But, as Feynman pointed out, our sense that at least in everyday life we can rely on solid, sensible physical contact to explain, say, why the butter knife comes to you when you pick it up, is a misconception. What does it mean to have physical contact? What exactly is happening when you pick up a knife, or push a swing, or make a wave in a waterbed by pressing down on it periodically? When we investigate deeply, we find that there is no physical contact. Instead, the electrical charges on your hand are influencing the electrical charges on the knife or swing or waterbed, and vice versa. Despite everyday experience and common sense, even here, there is only the interaction of electric fields. Nothing is touching anything.

前年六月非常自豪非常炫耀的向全世界发布的白皮书,亲自指挥、亲自部署,统揽全局、果断决策,号召全世界抄作业。结果被奥密克戎把脸都打肿了。德国之声的评论说:“ 若不是德尔塔退场,奥密克戎这个毒性更弱但传播力更强的变种上场,习的疫情叙述策略差点就在全世界取得成功。”

当初这个奥密克戎病毒变种按希腊字母顺序应该叫 Xi ,现在看来可能真是天意啊。

最近无聊的时候在skylinewebcams.com上看风景解不能出门旅行的馋。推荐几个自己比较心水的:

希腊科孚岛的海滩:清晨和黄昏都很好看,看小人人们玩水游泳很解压
skylinewebcams.com/en/webcam/e

希腊圣托里尼岛:会转动的webcam,既能看到海也能看到白色的房子,还能看到蓝顶教堂的尖。也是清晨和黄昏最美
skylinewebcams.com/en/webcam/e

西西里岛的海滩:一层层的海浪很好看
skylinewebcams.com/en/webcam/i

希腊Meteora的巨岩和修道院们:黄昏时候比较好看
skylinewebcams.com/en/webcam/e

土耳其卡帕多奇亚的山谷:日出时分运气好能看到满天热气球
skylinewebcams.com/en/webcam/t

希腊的Lake Kremasta:湖水颜色真好看啊

意大利北边的湖畔小城Alleghe:skylinewebcams.com/en/webcam/i

合作者的 intro 写得真好​,我都不知道我的 work 有这么重要 :Barbara_glowstick:

实在不知道怎样才能给 Appendix 从 A 开始编号并让 hyperref 链接到正确的地方,于是手动 \renewcommand{\thesection}{Appendix A}:aru_0160:

不过我前同事的论文都是创造一个问题,然后发现用某些现成的方法可以解决这个问题,感觉是比较工程的思维。而我的论文都是:我又发明了一个新方法,谁用得上就用吧​ :aru_0160:

咦今天来所里刚好撞见女同事要走,问了一下近况,她说昨天刚刚把论文交上去​:blobcatcomfreading:

看到朋友发的照片突然想笑:你德美丽的天际线里面总有一台吊车

关于宠物在家,转一个从别处看到的图,希望能有用可以帮到一些人

你德经常下一阵大雨然后出大太阳,这样是不是很有利于植物​:blobcatthinkingeyes:

再次感叹我真的好喜欢某前同事做的项目啊,怎么可以那么好玩,甚至是我来这个所的原因之一…
不过私下不怎么聊得来就是了…他之前经常来我办公室过问情况&闲聊,每次我都坐立不安想要赶紧逃跑…

看了 reddit 也有人叫 ducked… 感觉 duckducked 莫名有点萌

合作者笑死人了,我问他怎么知道 xxxx 的,他说“I googled”, 顿了一下又改口,”I duckcucked.”
所以 DuckDuckGo 的过去式是什么?DuckDuckWent?
