Protecting the borders from espionage is essential. It's something else to deny students because they are Chinese and hope to pursue a STEM degree in the United States. One night in 1978, President Jimmy Carter got a phone call at 3 a.m. from a top adviser who was visiting China. "Deng Xiaoping insisted I call you now, to see if you would permit 5,000 Chinese students to come to American universities," said the official, Frank Press. "Tell him to send 100,000," Mr. Carter replied.

去年，AI 能解出博士级别的数学题，已是轰动一时的大新闻； 而今年，能攻克「未解之谜」级别的数学难题的 AI 已经来了。 5 月 15 日，Google DeepMind 发布了全新编程智能体 AlphaEvolve。不同于传统的编程 Agent，它专注于通用算法的自动发现与持续优化。 顾名思义，AlphaEvolve 擅长在「进化」中寻找更优解，它模拟自然选择机制，能在代码中不断迭代、演化出创新算法。 只要问题能用程序表达、结果能用函数评估，AlphaEvolve 就能迭代算法。Google 表示，在组合数学、几何学、数论等超过 50 个未解问题中应用后，AlphaEvolve 在约 20% 的问题上超越了人类现有解法。 DeepMind 研究员 Matej Balog 表示：「AlphaEvolve 在十多个公开的数学问题上取得了突破。 但最让我激动的是：它找到了 56 年以来，4x4 复数矩阵乘法算法的首次改进。这个结果，来自它自创的一种复杂搜索算法。」 AlphaEvolve 的价值不仅在数学，它展现出的是一种通用的「算法发现能力」。Balog 表示：「我们对...

Duas Chinas habitam o imaginário americano: uma é uma superpotência tecnológica e manufatureira pronta para liderar o mundo. A outra é uma economia que está à beira do colapso. Cada uma delas reflete um aspecto real da China. Uma China — vamos chamá-la de China esperançosa — é definida por empresas como a DeepSeek, uma start-up de IA, a gigante dos veículos elétricos BYD e a potência tecnológica Huawei. Todas são líderes em inovação.
