SIKAP EINSTEIN TERHADAP EKSPERIMENNIM.: 22104050015Syifa Alifia AzzahraauthorThe relationship between theory and experiment is an important aspect of the development of science. Albert Einstein was a theoretical physicist who developed various scientific ideas through theoretical thinking and reasoning. However, in the development of his theories, Einstein continued to consider experimental results and observations. This study aims to analyze Einstein’s attitude toward experiments in the scientific process and its implications for the development of physics. This study employs a qualitative method using library research and a historical-philosophical approach. The data sources consist of Einstein’s works as primary sources, as well as books, journal articles, and other relevant scientific sources as secondary sources. The data were analyzed through the stages of heuristics, source criticism, interpretation, historiography, and philosophical analysis to examine Einstein’s attitude toward experiments. The results show that Einstein viewed theory and experiment as two complementary aspects. Einstein used theoretical reasoning to construct and develop scientific ideas, while experiments and observations played a role in testing the consistency of theories with empirical facts. This can be seen in Einstein’s response to various tests and observations of the theory of relativity, including the observation of the 1919 solar eclipse. In addition to empirical experiments, Einstein used thought experiments (gedanken experiments) as a means of developing and understanding theoretical ideas, rather than as a substitute for empirical testing. Thus, experiments play an important role in testing theories, while theories provide a basis for understanding and explaining experimental results.530.7 Pendidikan Fisika2026-08-13UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
