1. When was Walther Bothe born?January 8, 1891, in Germany
2. When did Walther Bothe die?February 8, 1957
3. What is Walther Bothe known for?Constructed Germany's first operational cyclotron
4. What is the nobel prize in physics?1954, shared with Max Born
5. Who was Walther Bothe?Walther Bothe was a German physicist who won a Nobel Prize for inventing the coincidence method, a clever way to study tiny particles.
6. What is the coincidence method?The coincidence method uses several detectors to record events that happen at the same time, which helps scientists see real particle interactions and ignore background noise.

Coincidence Method: An experimental technique in physics that relies on detecting two or more events occurring simultaneously to isolate specific phenomena.
Compton Effect: The scattering of a photon (like X-rays or gamma rays) by a charged particle, usually an electron, resulting in a decrease in photon energy.
Wave-Particle Duality: The quantum mechanical concept that all particles exhibit properties of both waves and particles.
Cyclotron: A type of particle accelerator that uses a magnetic field to guide charged particles in an outward spiral path, increasing their energy.
