Qhov sib txawv tseem ceeb ntawm quantum physics thiab quantum mechanics yog quantum physics yog ib ceg ntawm kev tshawb fawb uas tsom rau quantum mechanics whereas quantum mechanics yog cov thawj coj siv los piav qhia tus cwj pwm ntawm teeb meem thiab lub zog.
Tib neeg siv cov ntsiab lus 'quantum physics' thiab 'quantum mechanics' nrog lub ntsiab lus sib txawv. Txawm hais tias qee zaum peb siv cov ntsiab lus no los piav txog tib yam, muaj qhov sib txawv ntawm quantum physics thiab quantum mechanics. Peb tuaj yeem txheeb xyuas quantum physics ua ib ceg ntawm kev tshawb fawb uas kawm txog kev xav xws li quantum mechanics thiab quantum field theory. Hauv lwm lo lus, mechanics yog ib txheej ntawm kev xav uas peb kawm hauv ceg ntawm kev tshawb fawb hu ua physics.
Quantum Physics yog dab tsi?
Quantum physics yog ib ceg ntawm kev tshawb fawb uas tsom mus rau cov txheej txheem piav qhia los ntawm kev xav xws li quantum mechanics thiab quantum field theory. Cov kws tshawb fawb thiab cov kws tshawb fawb tsom mus rau thaj chaw no txhawm rau siv qhov kev paub no kom nkag siab txog tus cwj pwm ntawm cov khoom ntawm qib subatomic. Txawm li cas los xij, qee zaum peb siv cov lus "quantum physics" thiab "quantum mechanics" interchangeably.
Quantum Mechanics yog dab tsi?
Quantum mechanics yog txheej txheem ntawm kev piav qhia tus cwj pwm ntawm cov teeb meem ntawm atomic (los yog subatomic) nplai. Lo lus 'quantum' nws tus kheej piav qhia txog lub ntsiab lus tseem ceeb ntawm quantum mechanics - qhov quantized lossis discrete xwm ntawm teeb meem thiab lub zog.
Quantum mechanics tau yug los thaum Max Plank tau qhia txog lub tswv yim ntawm quantized zog (E=nhf) los piav qhia lub cev dub thermal tawg. Tom qab ntawd, Einstein tuaj nrog lub tswv yim ntawm 'photon' los piav qhia qhov xwm txheej ntawm lub teeb. Nws coj mus rau txoj kev xav hu ua 'wave-particle duality', uas piav qhia txog kev muaj ob qho 'yoj' thiab 'particle' zoo los ntawm cov teeb meem thiab lub zog. Louis de Broglie tau qhia txog lub tswvyim no.
Cov ntsiab lus tseem ceeb ntawm quantum mechanics kuj suav nrog Bohr qauv los piav txog cov qauv atomic los ntawm Niels Bohr, Schrödinger equation (kev sib npaug siv dav los xam quantum nthwv dej) los ntawm Erwin Schrödinger, lub hauv paus ntsiab lus tsis meej (uas piav qhia txog qhov tshwm sim ntawm qhov teeb meem thiab lub zog) los ntawm Werner Heisenberg, thiab Pauli Exclusion Txoj Cai los ntawm Wolfgang Pauli. Cov lus piav qhia hu ua Copenhagen txhais lus thiab qhov tshwm sim hu ua quantum entanglement kuj yog rau quantum mechanics.
Qhov txawv ntawm Quantum Physics thiab Quantum Mechanics yog dab tsi?
Quantum physics yog ib ceg loj ntawm kev tshawb fawb thaum quantum mechanics yog ib ceg ntawm quantum physics. Yog li, qhov sib txawv tseem ceeb ntawm quantum physics thiab quantum mechanics yog quantum physics yog ib ceg ntawm kev tshawb fawb uas tsom mus rau quantum mechanics whereas quantum mechanics yog cov thawj coj uas piav qhia txog tus cwj pwm ntawm teeb meem thiab lub zog.
Tsis tas li ntawd, quantum physics tuaj yeem kwv yees thiab piav qhia cov khoom ntawm lub cev lub cev thaum quantum mechanics tuaj yeem piav qhia txog cov khoom ntawm molecules, atoms thiab subatomic hais txog kev cuam tshuam ntawm lawv thiab nrog hluav taws xob hluav taws xob. Yog li ntawd, qhov no yog qhov txawv ntawm quantum physics thiab quantum mechanics nyob rau hauv cov nqe lus ntawm lawv siv.
Summary – Quantum Physics vs Quantum Mechanics
Txawm tias peb siv cov ntsiab lus quantum physics thiab quantum mechanics interchangeably, lawv txawv ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm quantum physics thiab quantum mechanics yog quantum physics yog ib ceg ntawm kev tshawb fawb uas tsom rau quantum mechanics whereas quantum mechanics yog cov thawj coj uas piav qhia txog tus cwj pwm ntawm teeb meem thiab lub zog.
