## BIG IDEAS - Starts at the beginning of the 20th century - Two revolutionary theories ## Modern Physics - Two revolutionary theories - [[Notes Vault/Physics Notes Vault/Relativity/Relativity|relativity]] - [[Albert Einstein]] (1905) stated space, time, and speed are not absolute. - measured length of an object traveling at high speeds is shorter. - time depends on the motion of the observer. - time dilation - gravity can affect time and space - quantum mechanics deals with subatomic particles - atoms are the smallest unit of matter. - atoms are constructed of smaller particles. - particle accelerators, study subatomic particles traveling at high speeds - discovery of Higgs-Boson particle - gives matter the property of mass. - relativistic quantum mechanics, attempt to marge relativity and quantum mechanics. Topics include: - [[Quantum mechanics]] - [[Nuclear physics]] - [[Particle physics]] - [[Special Relativity|Special theory of Relativity]] - [[General Relativity|General theory of Relativity]] ## Sources --- Return [[Home|Home]] | [[Science]] | [[Classical Physics]] | [[Modern Physics]] | [[Measurements]]
