Definition
Arthur Eddington was a British astronomer, physicist, and mathematician. He's famous for testing Einstein's theory of general relativity during a solar eclipse. Imagine him as the ultimate science explainer, making complex cosmic stuff understandable. Eddington helped confirm that gravity isn't just a force, but a curvature of space-time. He bridged the gap between theoretical physics and real-world observation. Think of him as the MythBusters of the early 20th century, but for astrophysics. His work revolutionized our understanding of the universe.
