ANECDOTE

Thomson and Everett

  • J.J. Thomson, head of the Cavendish Laboratory, was a theorist and known for his clumsiness.
  • A skilled glassblower, Ebenezer Everett, built Thomson's experimental apparatus.
INSIGHT

Subatomic Particles

  • Thomson's experiments revealed that the particles were 2,000 times smaller than hydrogen atoms.
  • This discovery indicated the existence of subatomic particles, a revolutionary concept at the time.
