Richard Feynman, a Nobel Prize-winning theoretical physicist, transformed quantum mechanics with his work on quantum electrodynamics (QED) and Feynman diagrams, intuitive tools for visualizing particle interactions. Born in 1918, his curiosity drove contributions to the Manhattan Project, where he helped develop the atomic bomb, and later investigations, like the Challenger disaster, where he exposed O-ring […]

Zero-Point Energy: Quantum Vacuum, Casimir Effect & Dark Energy
Zero-point energy (ZPE) is the lowest energy a quantum system can have, rooted in quantum mechanics and quantum field theory. It arises from the Heisenberg uncertainty principle, causing quantum fluctuations in the vacuum, even at absolute zero. The Casimir effect proves ZPE, showing plates attract due to vacuum energy pressure. The Lamb shift, a shift […]
