Abstract
In 2016 the LIGO-Virgo collaboration announced “the first direct detection of gravitational waves.” This was to distinguish their result from the indirect observation of Russell Hulse, Joel Weisberg, and Joseph Taylor, which used the decrease in the period of a binary pulsar to “establish, with a high degree of confidence the existence of gravitational radiation as predicted by general relativity.” This raises several interesting questions. One might ask how one can distinguish between direct and indirect observation and whether that distinction is exemplified in the practice of science. One might also ask whether a direct observation has more epistemic weight than an indirect observation. In this essay, I briefly discuss several episodes from the history of modern physics in an attempt to answer those questions. These episodes include Galileo and falling bodies, the discovery of the neutrino, the Higgs boson, and gravitational radiation.
期刊介绍：
Physics in Perspective seeks to bridge the gulf between physicists and non-physicists through historical and philosophical studies that typically display the unpredictable as well as the cross-disciplinary interplay of observation, experiment, and theory that has occurred over extended periods of time in academic, governmental, and industrial settings and in allied disciplines such as astrophysics, chemical physics, and geophysics. The journal also publishes first-person accounts by physicists of significant contributions they have made, biographical articles, book reviews, and guided tours of historical sites in cities throughout the world. It strives to make all articles understandable to a broad spectrum of readers – scientists, teachers, students, and the public at large. Bibliographic Data Phys. Perspect. 1 volume per year, 4 issues per volume approx. 500 pages per volume Format: 15.5 x 23.5cm ISSN 1422-6944 (print) ISSN 1422-6960 (electronic)
