The Problem of Elementary Particles (lecture series)

by Igor Yevgenyevich Tamm

Summary

This lecture series by Igor Yevgenyevich Tamm addresses the problem of what the world is made of by arguing that the ancient doctrine of the Four Elements has been superseded by chemistry, which reveals that the three kingdoms of nature are built up from some sixty-three elementary bodies. These true elementary bodies are compared to the letters of the alphabet, while the diversified compounds composing the material world are like the words forming a language. The lectures examine how a candle burning seems to disappear completely, leaving only an insignificant trace of ash, and challenge the Greek philosophical explanation that tallow contains an ethereal substance called Fire that is set free as flame.

The main themes include the nature of matter, its divisibility, and the atomic theory of chemistry as developed by John Dalton. Tamm explores the strange vicissitudes of particles of matter through the imagined life of an atom, from its existence as a rock-forming atom to its liberation by volcanic agency. A reader takes away an understanding that while the ancient doctrine is not wholly false—Fire representing imponderable agents like heat and light, and the remaining elements corresponding to the three physical states of matter—the true solution lies in the modern chemical understanding of elementary bodies that have never been decomposed into constituents.

Key concepts

  • Four ElementsThe ancient Greek doctrine that the world is made of fire, air, water, and earth, which Tamm argues has been exploded by chemistry but still represents imponderable agents and the three physical states of matter.
  • True elementary bodiesThe sixty-three chemical elements that have never been decomposed into constituents and serve as the fundamental building blocks of all material compounds.
  • Atomic theory of chemistryJohn Dalton's model of ultimate particles with relative weights, which provides the basis for understanding how elementary bodies combine to form compounds.
  • Imponderable agentsHeat, light, and electricity, which Tamm associates with the ancient element of Fire in his reinterpretation of the Four Elements doctrine.
  • Three physical states of matterThe gaseous, liquid, and solid forms of ponderable matter, which Tamm connects to the ancient elements of air, water, and earth respectively.
