History

Electron-based Technologies: Advances in electron-based technologies include improvements in semiconductor devices, such as transistors and integrated circuits, which have been crucial for the development of modern electronics and computing. High-Energy Physics: Ongoing research in high-energy physics, including experiments at facilities like the Large Hadron Collider (LHC), continues to explore the fundamental properties of electrons and […]

Quantum Computing: Research into quantum computing explores the use of qubits, which leverage quantum principles such as superposition and entanglement. Electrons play a key role in various qubit implementations, such as spin-based qubits and superconducting qubits. Precision Measurements: Modern experiments continue to refine the measurement of fundamental constants related to electrons, such as the electron […]

Standard Model: Electrons are an integral part of the Standard Model of particle physics, which describes all known fundamental particles and their interactions. Electrons are classified as leptons, which are elementary particles not subject to the strong nuclear force.

Quantum Tunneling: The phenomenon of quantum tunneling, where electrons can pass through energy barriers they would not be able to overcome classically, was confirmed experimentally. This effect has important applications in modern electronics, including tunnel diodes and scanning tunneling microscopes.

Ernst Ruska and Max Knoll (1931): The invention of the electron microscope allowed scientists to observe objects at a much higher resolution than with light microscopes. This technological advancement has had a profound impact on fields such as biology, materials science, and nanotechnology.

Richard Feynman, Julian Schwinger, and Sin-Itiro Tomonaga: These physicists developed Quantum Electrodynamics (QED), a theory describing the interaction of photons and electrons. QED is a cornerstone of quantum field theory and has been successful in making highly precise predictions about particle interactions.

Paul Dirac (1928): Dirac formulated an equation that combined quantum mechanics with special relativity, predicting the existence of antimatter. His equation described the behavior of electrons with remarkable accuracy and led to the discovery of the positron, the electron’s antiparticle.

Werner Heisenberg (1925): Heisenberg introduced matrix mechanics and the Uncertainty Principle, which stated that the exact position and momentum of an electron cannot be simultaneously measured with arbitrary precision. This principle challenged classical physics and laid the foundation for quantum mechanics. Erwin Schrödinger (1926): Schrödinger developed the wave equation, describing how the quantum state of […]

Niels Bohr (1913): Bohr proposed a new model that incorporated quantum theory. He suggested that electrons orbit the nucleus in fixed energy levels or shells and that they could only gain or lose energy by jumping between these levels. Bohr’s model explained the discrete spectral lines observed in atomic spectra and was crucial in advancing […]
