Definition

Proper noun: * Cecil Frank Powell: A British physicist who was awarded the Nobel Prize in Physics in 1950 for his development of the photographic method of studying nuclear processes and for his resulting discovery of the pion (pi-meson), a subatomic particle crucial to understanding the forces that hold the atomic nucleus together.

Usage Examples

• Proper noun:
  • Cecil Frank Powell pioneered a photographic technique to track cosmic rays.
  • The discovery of the pion by Cecil Frank Powell confirmed theoretical predictions about nuclear forces.
