最近被王虹的新闻刷屏了，这名数学家很有可能拿到2026年的菲尔茨奖。
王虹的履历并不是一个中国传统意义上数学天才的故事：高考数学只有130多分、没有参加过什么高级别的奥数竞赛拿过大奖、大学最开始学的也不是数学专业而是从其它专业转过来的。
这样一个非中国典型意义上的数学家能够冲击菲尔茨奖，无疑是给国内的数学教育一记震撼的。对应的，2022年获奖的韩裔许埈珥也是在硕士期间才转到数学专业的。这两人都不能算是数学天才型选手。
我自己觉得，其实不止是数学领域，会解题和真正的研究问题，其实是两个不太一样的技能，中国人更擅长解题，尤其是已经有明确定义的问题。

Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
