Iphepha Lefiziksi Yanamuhla
I-physics yesimanje iyigatsha lesayensi elizama ukuqonda izimiso eziyisisekelo ezilawula indawo yonke ngokuhlola izenzakalo ngezikali ezincane kakhulu nezinkulu. Ngokungafani ne-physics yakudala, encike kakhulu emithethweni yokuhamba ebikezelwayo njengoba ichazwe nguNewton kanye nezimiso ze-thermodynamic ezasungulwa ngekhulu le-19, i-physics yesimanje ihlola izindawo ze-quantum mechanics kanye ne-relativity. Leli phepha lihlose ukunikeza umbono jikelele walezi zinsika ezimbili ezibalulekile, lixoxe ngokutholwa okubalulekile, futhi liqokomise ucwaningo oluqhubekayo kanye nemiphumela engaba khona.
I-Quantum Mechanics
I-Quantum mechanics iwuhlaka lwethiyori oluchaza ukuziphatha kwezinhlayiya ezikalini ze-athomu kanye neze-subatomic. Enye yezinto eziyisisekelo ezisuka ku-classical mechanics umqondo we-wave-particle duality. Okuphakanyiswe nguLouis de Broglie, i-wave-particle duality ithi izinhlayiya ezifana nama-electron zibonisa kokubili izakhiwo ezifana namagagasi kanye nezinhlayiya kuye ngezimo zokuhlola.
Isimiso Sokungaqiniseki SaseHeisenberg
Isimiso sikaWerner Heisenberg Sokungaqiniseki siyitshe lesisekelo se-quantum mechanics. Sithi amabhangqa athile ezakhiwo zomzimba, njengesikhundla kanye nomfutho, awakwazi ukulinganiswa ngokunembile ngasikhathi sinye. Uma isici esisodwa silinganiswa ngokunembile, kulapho esinye singaziwa ngokunembile khona. Lesi simiso siphonsela inselelo isimo esinqunyiwe se-classical mechanics futhi sigcizelela isimo esingaba khona sezinhlelo ze-quantum.
Ukubeka Isikhundla Esiphezulu Nokubanjwa
I-Superposition ingumqondo wokuthi uhlelo lwe-quantum lungaba khona ezimweni eziningi ngasikhathi sinye. Lesi simiso siholela esimweni sokubanjwa kwe-quantum, lapho izinhlayiya ezimbili noma ngaphezulu zihlangana khona kangangokuthi isimo sesinye sithonya ngokushesha isimo sesinye (ezinye), kungakhathaliseki ukuthi ibanga elizihlukanisayo lingakanani. U-Albert Einstein wabiza lokhu ngokuthi "isenzo esithusayo esikude," yize kusukela lapho sekuqinisekiswe ngokuhlola.
Theory Frameworks
Isibalo sikaSchrödinger
U-Erwin Schrödinger wakha i-wave equation echaza indlela isimo se-quantum sesimiso somzimba esishintsha ngayo ngokuhamba kwesikhathi. I-Schrödinger's Equation iyisisekelo ekubikezeleni ukuziphatha nokusebenzisana kwezinhlayiya. Izixazululo zalesi sibalo zinikeza amathuba okuthola izinhlayiya esimweni esithile, okuhlanganisa isimo sokungenzeka se-quantum mechanics.
Ithiyori Yensimu Ye-Quantum
I-Quantum Field Theory (QFT) inweba i-quantum mechanics emasimini, iphatha izinhlayiya njengezimo ezijabulisayo zensimu engaphansi. Ihlanganisa ngempumelelo ukuhlobana okukhethekile kanye ne-quantum mechanics, ihlinzeka ngesisekelo se-Standard Model ye-particle physics. I-Standard Model ichaza amandla amathathu kwamane ayisisekelo emvelo: amandla kagesi, abuthakathaka, kanye namandla enuzi aqinile, kodwa ayihlanganisi amandla adonsela phansi.
Ukuhlobana
U-Albert Einstein waguqula i-physics ngemibono yakhe yobudlelwano obukhethekile nobujwayelekile, washintsha kakhulu ukuqonda kwethu isikhala, isikhathi, kanye namandla adonsela phansi.
Ukuhlobana Okukhethekile
I-Special Relativity eyanyatheliswa ngo-1905, yethula umqondo wokuthi imithetho yefiziksi iyafana kubo bonke ababukeli abanyakazayo ngendlela efanayo. Esinye sezambulo zayo ezinkulu ukuthi ijubane lokukhanya endaweni engenalutho lihlala njalo futhi alincikile ekunyakazeni komthombo wokukhanya noma umqapheli. Lokhu kwaholela emcabangweni wokuthi isikhala nesikhathi kuxhumene futhi kwakha i-continuum enezinhlangothi ezine eyaziwa ngokuthi i-spacetime.
General Relativity
Ngo-1915, u-Einstein wethula i-General Theory of Relativity, echaza amandla adonsela phansi hhayi njengamandla, kodwa njengokugoba kwesikhathi sesikhala okubangelwa ubuningi namandla. Izinto ezinkulu zibangela isikhathi sesikhala ukuba sigobe, futhi lokhu kugoba kunquma ukunyakaza kwezinto, umqondo odumile oboniswe ngokugoba kokukhanya okuvela enkanyezini ekude ezungeze ilanga, owaqinisekiswa ngesikhathi sokushona kwelanga ngo-1919.
Ukuhlangana kwe-Quantum Mechanics kanye ne-Relativity
Enye yezinselele ezinkulu ku-physics yanamuhla ukuvumelanisa izimiso ze-quantum mechanics nalezo zokuhlobana okujwayelekile. I-Quantum gravity, okuhlanganisa imibono efana ne-string theory kanye ne-loop quantum gravity, ifuna ukuthuthukisa i-quantum theory ehlanganisa izimiso zamandla adonsela phansi. Kodwa-ke, i-quantum gravity eyamukelekile ngokugcwele isalokhu ingaqondakali.
Izinto Ezibalulekile Ezitholwe Nezivivinyo
I-Higgs Boson
Ukutholakala kwe-boson ye-Higgs e-Large Hadron Collider ye-CERN ngo-2012 kwaba yimpumelelo enkulu. Kwaqinisekisa ukuba khona kwensimu ye-Higgs, enikeza izinhlayiya isisindo. Lokhu kutholakala kwaqinisekisa ingxenye yokugcina engakaqinisekiswa ye-Standard Model, yize kwavula imibuzo emisha mayelana ne-physics yezinhlayiya.
Amagagasi Adonsela phansi
Ngo-2015, i-Laser Interferometer Gravitational-Wave Observatory (LIGO) yathola amagagasi adonsela phansi okokuqala. Lawa magagasi ngesikhathi sesikhala, abikezelwa yi-General Relativity, akhiqizwa yizehlakalo ezimbi njengokuhlangana kwemigodi emnyama noma izinkanyezi ze-neutron. Lokhu kutholwa kwavula indlela entsha yokubuka indawo yonke, kuhambisana nezindlela zendabuko ezisekelwe emisebeni kagesi.
Ucwaningo Oluqhubekayo kanye Nemiphumela
I-Dark Matter kanye Namandla Amnyama
Cishe u-95% wendawo yonke yakhiwe ngezinto ezimnyama kanye namandla amnyama, ezingasebenzisani namandla kagesi, okwenza zingabonakali futhi zibonakale kuphela ngemiphumela yamandla adonsela phansi. Izinto ezimnyama zibonakala zisebenza njengesisekelo semithala, kuyilapho amandla amnyama eqhuba ukwanda okusheshayo kwendawo yonke. Ukuqonda lezi zingxenye eziyimfihlakalo kuyinto eza kuqala ku-physics yanamuhla.
I-Quantum Computing
I-Quantum computing isebenzisa izimiso zokubeka izinto endaweni eyodwa kanye nokunamathela ukuze yenze izibalo ngesivinini esidlula kakhulu amakhompyutha akudala emisebenzini ethile. Lawa madivayisi anamandla okuguqula izinkambu ezisukela ku-cryptography kuya kwisayensi yezinto.
Ukufuna Imibono Ehlangene
Ukufuna iTheory of Everything (TOE) ehlanganisa wonke amandla ayisisekelo, okuhlanganisa namandla adonsela phansi, kuyaqhubeka nokuphefumulela izazi zesayensi yethiyori. Ithiyori yezintambo, ephakamisa ukuthi izinhlayiya "ziyizintambo" ezinobukhulu obubodwa kunezinto ezifana namaphoyinti, iyindlela ehamba phambili. Kodwa-ke, isalokhu iwuhlaka lwezibalo oluzoqinisekiswa ngokuhlolwa.
Izicelo Ezisebenzayo
Izimiso zefiziksi yesimanje ziye zabangela intuthuko kwezobuchwepheshe njenge-semiconductors, i-laser, kanye ne-magnetic resonance imaging (MRI). Ukuqonda i-quantum mechanics kube negalelo elikhulu ekuthuthukisweni kwe-microelectronics, eyakha isisekelo sobuchwepheshe besimanje.
Isiphetho
I-physics yesimanje, ngokusebenzisa izinhlaka ze-quantum mechanics kanye ne-relativity, ishintshe kakhulu ukuqonda kwethu indawo yonke. Kusukela ezinhlayiyeni ezincane kakhulu ze-subatomic kuya ezindaweni ezinkulu zesikhala, le mibono inselele umbono wethu ngeqiniso futhi isunduza imingcele yolwazi lomuntu. Ngenkathi ukutholwa okubalulekile njenge-Higgs boson kanye namagagasi adonsela phansi kuqinisekisa ukuqina kwezakhiwo zesimanje zethiyori, imibuzo eminingi isalokhu ingaphendulwa. Umzamo oqhubekayo wokuqonda udaba olumnyama, amandla amnyama, kanye nokuthuthukisa ithiyori ehlangene ehlanganisa i-quantum mechanics kanye namandla adonsela phansi, emele umngcele wesayensi yemvelo. Ngokwenza kanjalo, i-physics yesimanje ayigcini nje ngokujulisa ukuqonda kwethu indawo yonke kodwa futhi ivula indlela yokusungula izinto ezintsha zobuchwepheshe ezingakha kabusha ikusasa lethu.
