Awarded the Nobel Prize for physics in 1918, German physicist Max Planck is best remembered as the originator of the quantum theory. His work helped usher in a new era in theoretical physics and revolutionized the scientific community’s understanding of atomic and subatomic processes. Planck introduced an idea that led to the quantum theory, which became the foundation of 20th century physics. In December 1900, Planck worked out an eqation that described the distribution of radiation accurately over the range of low to high frequencies. He had developed a theory which depended on a model of matter that seemed very strange at the time. The model required the emission of eletromagnetic radiation in small chunks or particles. These particles were later called quantums. The energy associated with each quantum is measured by multiplying the frequency of the radiation in by a universal constant, h. Thus, energy, or E, equals hv. The constant, h, is known as Planck’s constant. It is now recognized as one of the fundamental constants of the world. Planck announced his findings in 1900, but it was years before the full consequences of his revolutionary quantum theory were recognized. Throughout his life, Planck made significant contributions to optics, thermodynamics and statistical mechanics, physical chemistry, and other fields. In 1930 he was elected president of the Kaiser Wilhelm Society, which was renamed the Max Planck Society after World War II . Though deeply opposed to the facist regime of Adolf Hitler, Planck remained in Germany throughout the war. He died in Gottingen on October 4, 1947.
The implication in this passage is that______.
选项
A、only a German physicist could discover such a theory
B、quantum theory, which led to the development of 20th century physics, is basically a mathematical formula
C、Planck’s constant was not discernible before 1900
D、radiation was hard to study
答案
B
解析
本文暗示,导致20世纪物理学发展的量子理论基本上是一个数学公式。根据本文第三句和第四句,普兰克提出的一个观点导致量子理论的产生,该理论成为20世纪物理学的基础。1900年12月,普兰克确立了一个方程,准确地描述射线低频和高频值域的分布情况。
