Quantum computers utilize quantum mechanics to enhance computational power. Quantum bits exist in superposition of values from 0 to 1. A 30-qubit quantum computer could match supercomputer's TFLOPS speed
Quantum mechanics deals with extremely tiny objects and their behavior. Three revolutionary principles emerged between 1900 and 1930. Quantized characteristics describe properties like location and speed. Light can exhibit both wave and particle properties. Matter can behave as waves
Space is a three-dimensional continuum containing positions and directions. Modern physics views space as part of four-dimensional spacetime. Space is fundamental to understanding physical universe
Ancient Egyptians practiced trepanation for brain injuries and mental disorders. Hippocrates challenged heart as center of intelligence. Galen observed mental faculties lost with brain damage. Medieval Muslim world described brain-related medical problems
Siemens began MRI research in 1959 using magnets to study plastics. Physicist Alexander Ganssen developed first medical MRI system in 1966. First MRI prototype built in 1978 with 0.1 Tesla superconducting magnet. Bell pepper test image in 1979 convinced management of technology's potential
Revolutionized medicine during Crimean War with ether anesthesia and improved surgical methods. Introduced plaster casts and created detailed anatomical atlas. Trained many future healers including Garibaldi
