The Distribution of an Illustrated Timeline Wall Chart and Teacher's Guide of 20th Century Physics

人们普遍认为物理学在20世纪的伟大科学成就中起了重要作用。为了庆祝1999年美国物理学会（APS）成立100周年，APS委托制作了一张时间轴挂图，描绘了20世纪物理学的重大事件和应用。时间线挂图由11个面板组成，横跨20世纪，并按照五(5)条时间线排列，列出物理学对基础知识和应用技术的发现和贡献。五（50）股包括1)宇宙：非常大的天文学和宇宙学的世界；2)人类尺度：我们生活的物理世界，从宏观到微观；3)原子：由原子、原子核、粒子及其组成部分组成的小世界；4)生活世界：物理学在生物学和医学中的作用；5)技术：基础和应用物理学的影响及其在日常生活中的作用。时间线挂图是为了吸引高中生和非理科生而编写和说明的。作为美国科学学会百年纪念活动的一部分，美国科学学会计划印制2万份时间表挂图，然后免费分发给美国的每一所高中、两年制和四年制学院和大学，以及其他适当的机构，如科学博物馆、研究实验室和科学图书馆。教师的时间轴挂图指南将随时间轴一起准备和分发。此外，将开发一个基于时间线挂图事件和插图的网站。

It is widely recognized that physics has played a major role in the great scientific achievements of the 20th century. To celebrate the 100th anniversary of the establishment of the American Physical Society (APS) in 1999, the APS has commissioned the production of a timeline wall chart depicting the major events and applications of 20th century physics. The timeline wall chart consists of 11 panels, spanning the 20th century and is organized along five (5) timeline strands listing discoveries and contributions of physics to basic knowledge and applied technologies.The five (50) strands include 1) COSMIC: the world of the very large of astronomy and cosmology; 2) HUMAN SCALE: the physical world we live in from the global to the microscopic; 3) ATOMIC: the world of the small, atoms, nuclei, particles, and their constituents; 4) LIVING WORLD: the role of physics in biology and medicine, and 5) TECHNOLOGY: the impact of basic and applied physics and its role in everyday life. The timeline wall chart is written and illustrated so as to be attractive to high school students and non-science college students.As part of the APS Centennial celebration, the APS plans to have 20,000 copies of the timeline wall chart printed and then distributed free of charge to every high school, two- and four-year college and university, as well as other appropriate institutions such as science museums, research laboratories and science libraries in the United States. A teacher's guide to the timeline wall chart will be prepared and distributed with the timeline. In addition, a web site based on timeline wall chart events and illustrations will be developed.
