The Timeline

400 BCE — 2020

  1. 400 BCE

    Democritus' Atomic Theory

    Democritus proposed that matter is composed of small, indivisible particles called atoms. This early idea laid the groundwork for the later development of atomic theory.
  2. 350 BCE

    Aristotle's Four Elements

    Aristotle introduced the concept of matter being composed of four elements: earth, water, air, and fire. This idea dominated Western thought for centuries.
  3. 1661

    Robert Boyle's "The Sceptical Chymist"

    Robert Boyle published "The Sceptical Chymist," challenging the Aristotelian view of elements and laying the foundation for modern chemistry.
  4. 1789

    Antoine Lavoisier's Law of Conservation of Mass

    Antoine Lavoisier formulated the Law of Conservation of Mass, stating that matter is neither created nor destroyed in chemical reactions.
  5. 1803

    John Dalton's Atomic Theory

    John Dalton proposed that elements are made of tiny, indivisible particles called atoms, each with a specific weight, advancing the concept of matter.
  6. 1869

    Dmitri Mendeleev's Periodic Table

    Dmitri Mendeleev created the Periodic Table, organizing elements based on their atomic weights and properties, which enhanced the understanding of matter's structure.
  7. 1897

    Discovery of the Electron

    J.J. Thomson discovered the electron, revealing that atoms were divisible and had internal structure, furthering the concept of matter.
  8. 1911

    Rutherford's Nuclear Model

    Ernest Rutherford proposed the nuclear model of the atom, with a dense nucleus surrounded by electrons, refining the understanding of atomic structure.
  9. 1913

    Bohr's Model of the Atom

    Niels Bohr introduced a model of the atom with electrons orbiting the nucleus in fixed paths, explaining atomic emission spectra.
  10. 1926

    Schrödinger's Wave Mechanics

    Erwin Schrödinger developed wave mechanics, describing electrons as wave functions, which revolutionized the concept of atomic and molecular structure.
  11. 1932

    Discovery of the Neutron

    James Chadwick discovered the neutron, completing the basic understanding of atomic particles and enhancing the concept of matter.
  12. 1947

    Discovery of the Transistor

    The invention of the transistor by John Bardeen, Walter Brattain, and William Shockley revolutionized electronics and material science.
  13. 1964

    Quark Model Proposed

    Murray Gell-Mann and George Zweig proposed the quark model, explaining the substructure of protons and neutrons, refining the concept of matter at a fundamental level.
  14. 1985

    Discovery of Fullerenes

    The discovery of fullerenes, a new form of carbon, by Harold Kroto, Robert Curl, and Richard Smalley expanded the understanding of carbon's versatility.
  15. 2012

    Discovery of the Higgs Boson

    The discovery of the Higgs boson at CERN confirmed the mechanism that gives mass to elementary particles, a critical development in the concept of matter.
  16. 2020

    Advancements in Quantum Computing

    Significant progress in quantum computing demonstrated the manipulation of matter at quantum levels, opening new possibilities for technology and material science.
