经典教材《泛函分析》作者逝世,享年99岁:首位获阿贝尔奖的应用数学家
量子位· 2025-05-18 05:20
金磊 发自 凹非寺 量子位 | 公众号 QbitAI 史上首位获得阿贝尔奖(数学界诺奖)的应用数学家 Peter Lax (彼得·拉克斯)逝世了,享年 99岁 。 或许你对这个名字不太熟悉,但你很可能学过他编写的那个经典教材—— 《泛函分析》 。 纵观他的一生,拉克斯可以说是站在理论数学和应用数学 交叉点 的巨匠。 同时,他也是 最早将计算机技术应用于数学分析的先驱之一 。 拉克斯所提出的众多经典理论和方法,至今仍然广泛地应用于科学研究和工程实践中。 不仅如此,除了那本耳熟能详的《泛函分析》之外,他所编写的很多教材也被莘莘学子们所青睐。 包括 《微积分及其应用》 、 《线性代数及其应用》 等等。 用网友的话来评价就是: 能把分析的知识写的像给大众的科普读物一样,也就是数学大师的功力了。 值得一提的是,今年5月1日拉克斯刚刚过完他99岁的生日,阿贝尔奖官方亲自发文祝贺,并给予了这样的评价: 拉克斯在将纯数学和应用数学结合在一起方面表现突出。 他的影响深远,不仅体现在他的研究,还体现在他的著作、他对教育的终身承诺以及他对年轻数学家的慷慨。 对此,《纽约时报》在讣告中评价他为"重新定义了数学在计算机时代的角色",而 ...

Group 1 - The concept of the Boltzmann Brain suggests that in an infinitely old and chaotic universe, random fluctuations could create a brain with complete memories and self-awareness without the need for a complex external world [1][2][3] - The probability of a Boltzmann Brain existing is argued to be higher than that of a low-entropy universe evolving into a complex structure, as the latter requires overcoming significant entropy increase [2][3] - This leads to the unsettling conclusion that human existence might be a fleeting phenomenon resulting from a random quantum fluctuation, challenging fundamental perceptions of reality [5][6] Group 2 - The discussion contrasts the Boltzmann Brain with Laplace's Demon, which represents determinism, suggesting that all thoughts and feelings are predetermined by physical laws [11][12] - Both perspectives imply that free will does not exist, whether through extreme randomness or absolute determinism [12][18] - Kant's philosophy attempts to reconcile these views by suggesting that true freedom exists beyond observable reality, yet this remains a scientific mystery [18][19] Group 3 - The insights from Boltzmann and Darwin regarding how order emerges from disorder provide a different perspective on evolution and consciousness [19][20] - Boltzmann's view redefines survival competition as a struggle for "negative entropy," indicating that life extracts order from its environment to maintain complexity [20] - This suggests that consciousness may be a product of evolutionary processes aimed at better perceiving the world and utilizing resources effectively [21][22] Group 4 - The exploration of consciousness requires a multidisciplinary approach, incorporating insights from cognitive science, philosophy, and neuroscience [40][42] - Various theories, such as Hofstadter's "strange loop," Turing's computationalism, and integrated information theory (IIT), challenge traditional notions of consciousness and its location [42][43][44] - These perspectives indicate that consciousness may not reside in a specific location but rather in the organization and flow of information within a system [46][47] Group 5 - The evolution of AI, particularly through models like the Boltzmann machine, reflects the potential for understanding consciousness through complex information processing [26][31][33] - The Boltzmann machine's design, which incorporates randomness and probabilistic learning, parallels the idea that consciousness may emerge from structured interactions within a chaotic environment [34][38] - This suggests that consciousness could be a result of cumulative processes rather than a singular miraculous event [38][39]
