Abstract: I review the core ideas in Scattering Amplitudes.  I discuss techniques and the drive for precision physics, focusing on applications to Quantum Chromodynamics and to gravitational waves.

Bio: David Kosower was born in New York and received his PhD from Harvard University in 1986. Following postdoctoral positions at Columbia, Fermilab, and CERN, he took up a permanent position at the Institut de Physique Théorique (IPhT), Saclay. Prof. Kosower has also served as a visiting professor or scientist at the University of Zurich, the Weizmann Institute, Caltech, the Institute for Advanced Study, the Chinese Academy of Sciences (ITP, Beijing), and CERN.
His research interests include Scattering Amplitudes, Quantum Chromodynamics (QCD), and gravitational waves. He has made pathbreaking contributions to the calculation of perturbative scattering amplitudes, leading to a deeper understanding of quantum field theory and providing powerful new tools for computing processes in QCD and gravity. His contributions have been widely recognized; he is the recipient of the 2014 J.J. Sakurai Prize from the American Physical Society and the 2023 Galileo Galilei Medal.
个人简介：大卫·科索尔出生于纽约，1986年获得哈佛大学博士学位。在哥伦比亚大学、费米实验室和欧洲核子研究中心完成博士后研究后，他于法国萨克雷理论物理研究所获得长期职位。科索尔教授还曾担任苏黎世大学、魏茨曼科学研究所、加州理工学院、普林斯顿高等研究院、中国科学院理论物理研究所及欧洲核子研究中心的客座教授或访问科学家。
他的研究领域涵盖散射振幅、量子色动力学与引力波。他在微扰散射振幅计算方面做出了开创性贡献，不仅为量子色动力学和引力相关过程的计算提供了强大新工具，更深化了人们对量子场论的理解。其学术成就获得广泛认可，曾荣获2014年美国物理学会樱井奖以及2023年伽利略·伽利莱奖章。
