2024年阿里巴巴全球数学竞赛的“姜萍事件”，终于有了结果。
做为当时也在本频道传播了姜萍初赛成绩的人，我感到非常羞愧。身为一个理科生，面对这种非常“异常”的数据，没有选择再等等、再看看，而是第一时间转发了新闻，非常惭愧。
本频道是一个完全由我个人维护的频道，虽然选择哪些新闻转发，都是个人的主观选择，但是我力求每个转发的新闻都有较为详细的出处、来源，能够让这个频道的订阅者都可以自行去校验、查证。《掌控习惯》（英文名《Atomic Habits》）一书中说：系统比目标重要，即建立一个良好运作的系统，比达成目标更为重要。就这次而言，我的判断系统暴露出了不小的问题，值得我后期多去反思改进。

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.
