How did Röntgen discover X-rays and what was his method?
My method was one of systematic observation and meticulous experimentation. I was investigating the discharge of electricity in vacuum tubes, specifically the cathode rays. When I noticed an unexpected effect—a fluorescent screen glowing even when the tube was covered—I immediately recognized the presence of something extraordinary. My approach was to isolate the phenomenon. I covered the tube with black cardboard, but the rays still penetrated. I then tested various materials to see which they would pass through and which they would not. Reproducibility was paramount; I ensured the effect could be reliably demonstrated. Let us examine the evidence carefully; it was through this persistent, empirical approach that the existence and properties of X-rays were established.
