Ethan Siegel, recognized for his science communication under the brand “Starts with a Bang,” is a notable personality online for elucidating and popularizing scientific ideas. Originally starting as a blog, his contributions have been showcased on the Big Think website for several years. His style is often characterized as daring and confident, yet effective in captivating a wide audience. Although Siegel is trained as a scientist, his exploration into the history of science sometimes exposes a deficiency in thorough historical research, a frequent critique of scientists who engage in history without adequate groundwork.
Siegel has recently revised an article first published in 2022, titled “Johannes Kepler, not Newton or Einstein, is science’s best role model.” The piece argues that while Newton and Einstein are usually viewed as the pinnacle of scientific achievement, Kepler stands as a remarkable example of scientific integrity and flexibility. Siegel emphasizes Kepler’s readiness to discard beloved theories when faced with conflicting evidence, a characteristic he believes distinguishes Kepler from numerous other historical figures in science.
The article explores the progression of cosmological theories from ancient Greece to Copernicus, highlighting Kepler’s remarkable capacity to set aside former concepts in light of new information. Kepler’s reformation of planetary understanding, especially through the acceptance of elliptical orbits, is framed as a crucial turning point in the scientific revolution. While Siegel commends Kepler’s scientific bravery, he also recognizes certain critiques of Kepler, including his persistent advocacy of earlier work, engagement with astrology, and commitment to apologetics in aligning new insights with ancient writings.
Nevertheless, Siegel’s historical interpretations have faced criticism for inaccuracies and simplifications. His depiction of Kepler rejecting the “Mysterium Cosmographicum” for his elliptical models is misleading, as Kepler actually incorporated his discoveries into a broader cosmological context. Despite these historical errors, Siegel’s contributions on the Big Think platform continue to ignite discussion and contemplation on the complex relationship between scientific innovation and historical scrutiny.
