Core Viewpoint - Peter Lax, the first applied mathematician to receive the Abel Prize, passed away at the age of 99, marking the end of an era in mathematics and science [1][49]. Group 1: Contributions to Mathematics - Lax was a pioneer in applying computer technology to mathematical analysis and made significant contributions that are still widely used in scientific research and engineering practices [4][5]. - His notable works include the classic textbook "Functional Analysis" and other widely appreciated texts such as "Calculus and Its Applications" and "Linear Algebra and Its Applications" [2][6][7]. - Lax's research spanned various fields, including partial differential equations, fluid mechanics, numerical computation, scattering theory, and integrable systems, leading to profound theoretical results and practical algorithms [33]. Group 2: Awards and Recognition - Lax received numerous prestigious awards, including the National Medal of Science in 1986 and the Wolf Prize in 1987, culminating in being the first applied mathematician to win the Abel Prize in 2005 for his foundational work in partial differential equations [35][36]. - The Abel Prize committee described him as "the most versatile mathematician of his generation," highlighting his broad impact on the field [37]. Group 3: Personal Background and Legacy - Born on May 1, 1926, in Budapest, Lax showed exceptional mathematical talent from a young age, influenced by his family and mentors [15][16][17]. - His experiences during World War II, including his work on the Manhattan Project, shaped his understanding of the importance of computation in science [23][24][25]. - Lax's legacy includes not only his research and publications but also his commitment to education and mentorship, having trained over 55 doctoral students [46].
