Definition

Proper noun A Japanese theoretical physicist. He is renowned for his 1935 prediction of the existence of the meson, a subatomic particle that mediates the strong nuclear force holding atomic nuclei together. For this pioneering work, which provided a theoretical foundation for nuclear forces, he was awarded the Nobel Prize in Physics in 1949. He was the first Japanese Nobel laureate.

Usage Examples

• Proper noun:
  • Hideki Yukawa made a groundbreaking contribution to particle physics.
  • The Yukawa potential, named after Hideki Yukawa, describes the force between nucleons.
  • In 1949, Hideki Yukawa received the Nobel Prize.

Advanced Usage

• "Yukawa interaction": The short-range interaction between particles, such as nucleons, mediated by the exchange of mesons, as theorized by Hideki Yukawa.
  • The strong force is often modeled using a Yukawa interaction.
• "Yukawa potential": A mathematical potential describing the force field associated with the Yukawa interaction. It decreases exponentially with distance.
  • The Yukawa potential is crucial for understanding nuclear binding.

Variants and Related Words

• Yukawa (adj): Used attributively to denote concepts stemming from his work.
  • Yukawa theory, Yukawa particle.
• Meson (n): The type of particle whose existence Yukawa predicted.
• Pion (n): The lightest type of meson, identified as the particle mediating the nuclear force in Yukawa's theory.

Synonyms

• Nobel laureate in Physics (1949)
• Theoretical physicist

Related Phrases and Terms

• Nuclear force: The strong, short-range force between protons and neutrons in an atomic nucleus, which Yukawa's work aimed to explain.
• Quantum field theory: The theoretical framework within which Yukawa's meson theory was developed.
• Particle exchange: The concept that forces are mediated by the exchange of particles, central to Yukawa's prediction.

Noun

1. Japanese mathematical physicist who proposed that nuclear forces are mediated by massive particles called mesons which are analogous to the photon in mediating electromagnetic forces (1907-1981)
