The New Physics and Its Evolution

"The New Physics and Its Evolution" by Lucien Poincaré is a book that explores the significant advancements in physics during the early 1900s. Poincaré explains the newest scientific ideas in a way that's easy to understand, not just for experts but also for anyone with a good education. He talks about how modern physics has changed over time, how new discoveries relate to each other, and how they build upon older, basic theories. He notes that while some think these changes are sudden and revolutionary, they're actually part of a long, steady progress, like past discoveries in electricity. The author points out that new findings, like X-rays and ideas about what matter is made of, have made people think more deeply about big questions like what exists and how physical laws work, setting the stage to investigate subjects like measurement, the development of core scientific ideas, and how different parts of physics are linked.
