 solar-system× 140 The Sun plus the collection of bodies in orbit around the Sun such as planets, dwarf planets, moons, asteroids, comets, etc. solar-system-exploration× 18 solar-wind× 10 solid-mechanics× 24 solid-state-physics× 308 Solid-state physics studies how macroscopic properties of solids (mechanical, electrical, optical, etc.) result from their microscopic structure. It usually deals with the scale where quantum properti… solitary-waves solitons× 22 solstice× 3 sound space× 193 The near-vacuum extending between the planets and stars, containing small amounts of gas and dust. Also called outer space to refer to the physical universe beyond the Earth's atmosphere. space-expansion× 165 space-mission× 28 spacetime× 345 As a consequence of the Lorentz transformations, time and space transform into each other when changing reference frame. This calls for a unified description: Minkowski spacetime. spacetime-metric space-travel× 52 special-functions× 6 special-relativity× 1000 The special theory of relativity describes the motion and dynamics of objects moving at significant fractions of the speed of light. specific-reference× 326 for questions seeking a single specific paper or a short, non-open-ended list of references, like "What paper first discovered X?", "Where can I find the original derivation of X?", or "W… spectroscopy× 116 the practice of separating a signal by frequency (or sometimes energy or momentum) and analyzing the resulting spectrum. speed× 111 the magnitude of velocity. speed-of-light× 379 fundamental universal constant that marks the maximum speed at which information can propagate. Its value is $299792458\frac{\mathrm{m}}{\mathrm{s}}$. spherical-harmonics× 14 spin× 258 Fundamental characteristic property of particles which together with orbital angular momentum acts as the generator of rotations and which doesn't have a classical equivalent but is sometimes compared… spin-chains× 13 spin-glass× 4 spin-model× 24 spinors× 57 spin-statistics× 39 sports× 9 spring× 119 An object such as a metal coil or air-filled tube which provides a force opposing the direction of deformation. sr st stability× 52 standard standard-model× 253 A model of the basic particles and forces featuring six quarks, three charged leptons, three massless neutral leptons and four fundamental force carrying bosons.
