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。

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.
Telegram is riding high, adding tens of million of users this year. Now the bill is coming due.Telegram is one of the few significant social-media challengers to Facebook Inc., FB -1.90% on a trajectory toward one billion users active each month by the end of 2022, up from roughly 550 million today.
