About Lesson
- Antoine Lavoisier – Established the law of conservation of mass, fundamental to chemical reactions.
- Dmitri Mendeleev – Developed the periodic table, organizing elements based on their properties.
- J.J. Thomson – Discovered the electron, contributing to atomic structure understanding.
- Ernest Rutherford – Conducted the gold foil experiment, discovering the nucleus of the atom.
- Niels Bohr – Developed the Bohr model of the atom, introducing quantized electron orbits.
- Marie Curie – Discovered radioactivity, advancing knowledge on nuclear reactions.
- John Dalton – Proposed the atomic theory, stating that matter is composed of atoms.
- Willard Libby – Developed radiocarbon dating, a method for determining the age of ancient biological materials based on the decay of carbon-14 isotopes.
- Max Planck – Introduced quantum theory, demonstrating that energy is emitted in discrete units (quanta), forming the foundation of modern quantum mechanics.
- Albert Einstein – Explained the photoelectric effect, proving that light behaves as both a particle and a wave, which was key to quantum mechanics.
- Werner Heisenberg – Formulated the Uncertainty Principle, which states that the position and momentum of a particle cannot be simultaneously measured with absolute precision.
- Erwin Schrödinger – Developed wave mechanics, providing a mathematical model for quantum states of atoms and molecules.
- Henri Becquerel – Discovered radioactivity, which led to the later work of Marie Curie in identifying radioactive elements.
- Enrico Fermi – Pioneered work in nuclear reactions, leading to the development of the first nuclear reactor and significant advances in atomic energy.
