我其实不是一个特别的甜品胃，吃不吃大部分时候都行。可能是自小甜品就和特殊的日子有着强关联，所以多多少少甜品店也就成为了人生特殊时刻记忆的一部分。先从当年在巴塞罗那讲起吧。当时有幸在市中心上学，旁边就有一家甜品店bubó。那时候每当考完试，就会被好友拉过去点个甜品庆祝一番。记得印象最深的是他家的best chocolate cake award得奖单品，对我这么一个喜欢水果胜过巧克力的人来说，也是非点不可的。若干年后故地重游，唤醒了味蕾的记忆，也是对于青春的一场缅怀。后面住在三藩，最喜欢的甜品有两家。一家是Tartine及其经典的passion fruit coconut cake，另一个则是家旁边的Neighbor Bakehouse。Tartine是白月光，见证了无数的纪念日。Neighbor Bakehouse是日常，开启每个慵懒的周末。在巴黎的时候，也有幸尝到了很多赞誉无数的甜品。然而就像米其林不能天天吃一样，太高端的甜品也是更多在于偶尔的体验而非日常的陪伴。最让我念念不忘的，其实是楼下的一家Eric Kayser。他家其实是连锁，所以并不算得上是多么高端。但有点时间我长胖数斤的元凶就是每天早晨deux croissants。经典黄油的香气，戒掉真的很难。自从被巴黎养的口味叼叼的，回到湾区就再也吃不下凑数的牛角可颂。类似的记忆还有Los Gatos 那家Fleur de Co ...继续阅读 (30)

遇到了一个有趣的问题，正好落在 AI 模型的能力边界处：试证明不可能把平面分成无穷个圆的无交并。在我尝试的所有模型里，只有 GPT 5 thinking model 成功做了出来（虽然花了点时间）。有趣的不是这个结论，而是观察它们的思路。所有失败的模型都有个共同点：它们的思考基本上是从文字到文字的。它们会调用自己脑海中各种已有的定理和知识，然后漫无目的地试图拼凑出一个证明，但所有这些定理，不管是拓扑的还是几何的还是测度的，对它们来说都是纯粹字面意义上的陈述。Qwen 的思考过程最典型：它滔滔不绝想了很久，但很显然从头到尾它都并不真的理解它在说什么。圆也罢，开集闭集也罢，Baire 纲定理也罢，对它来说都是纯粹的概念，给人的感觉是它甚至并不真的知道「圆是圆的」。微妙之处在于，这种「没有几何直觉的几何思考」在某些时候其实未必是一种劣势。现代数学早已挣脱了对三维现实想象的依赖，大部份数学思考本来也确实是在纯粹的概念思辨空间中进行（特别是当问题进入代数乃至范畴论的领域的时候，这时从概念到概念的思考就变成了一种必然）。有的时候，几何直觉甚至反而会成为一种束缚，特别是当思考高维空间的时候，基于低维现实的直观常常是有误导性的。在这些问题上，AI 的「盲目」反而带来了自由，使得它不必受困于视觉直觉。——当然，人类的视觉直觉可能会渗透进人类的文本语料里，在某种程度上「污染」AI，但这是另一个问题。然 ...继续阅读 (24)

GPT 5 推出之后大家照例让它算 10.9 和 10.11 的差。它照例失败了，成了新一轮笑柄。倒是真的实现了传说中的 Ph.D level，因为博士生一般来说算术都不好。当然这不是它一家的问题，别家 AI 也在这个简单的题目上纷纷翻车，包括我很喜欢用的 Gemini Pro 2.5。但 Gemini 翻车的姿势还要更炫酷一点：作为一款思维链模型，它知道这种时候应该调用 Python 来算。但当 Python 返回了正确结果之后，它的反应居然是：「我觉得 Python 算的不对，还是我自己来心算好了。」然后算错了。这个错误虽然好笑，但暴露的是这一整轮 agentic AI 发展的致命弱点。Agentic AI 作为一个框架要能运行，前提条件是 AI 知道什么时候该使用并依赖外部工具。当然，这里的分界是模糊的：一个小孩子如果在算三位数乘法的时候掏出计算器，你不会批评。如果这个小孩算一位数乘法也要用计算器，你会怀疑是不是智力有点问题——当然无论如何至少结果是对的，但你会心想一个高级一点的大脑是不是应该合理判断这个问题不值当用外部工具。而现在的问题是这个小孩算一位数乘法，掏出计算器算了个结果，然后觉得不对扔掉了，自己心算了一个错误的答案出来。这是人类有可能犯的错误吗？其实也是。而且如果你细想，这恰恰是非常「人类」的错误。人类的思维之所以不可靠，就是因为我们常常把直觉凌驾于客观证据之上。 ...继续阅读 (22)
