Ukudluliswa kwedatha yedijithali kuyisisekelo sokuxhumana kwesimanje. Ngaphandle kokudluliswa kwedatha yedijithali, i-inthanethi, omakhalekhukhwini, kanye namanye amadivayisi amaningi kagesi ngeke kusebenze. Lesi sihloko sizoxoxa ngezimiso eziyisisekelo zokudluliswa kwedatha yedijithali, ubuchwepheshe obusetshenziswayo, kanye nezinhlelo zokusebenza ezahlukahlukene kanye nezinselelo ezibhekene nazo. Izimiso Eziyisisekelo Zokudluliswa Kwedatha Yedijithali Ukudluliswa kwedatha yedijithali kuyinqubo yokuthumela idatha… Funda kabanzi

Isitoreji Sedatha Yedijithali: Ubuchwepheshe Nokuvela Kwayo Isitoreji sedatha yedijithali singenye yezici ezibaluleke kakhulu zesikhathi sobuchwepheshe bolwazi banamuhla. Kuleli zwe elihlala lishintsha, isidingo sokugcina, ukuphatha, nokufinyelela idatha ngokushesha nangendlela efanele sesibe yinto ebalulekile. Lesi sihloko sizoxoxa ngobuchwepheshe bokugcina idatha yedijithali, kusukela emlandweni wayo kuya ekuthuthukisweni kwayo… Funda kabanzi

Umphumela We-Photoelectric, Umphumela We-Compton, kanye Ne-X-Rays Isingeniso Ekuqaleni kwekhulu lama-20, izivivinyo eziningana ezibalulekile zashintsha ukuqonda kwethu uhlobo lokukhanya nezinto. Izenzakalo ezintathu ezibalulekile—umphumela we-photoelectric, umphumela we-Compton, kanye ne-X-ray—zidlale indima ebalulekile ekuthuthukisweni kwe-physics yanamuhla. Lesi sihloko sizoxoxa ngesinye salezi zimo, ukuthi zatholakala kanjani, kanye nemiphumela yazo kanye nokusetshenziswa kwazo ku… Funda kabanzi

Umqondo Wezithombe Isingeniso Ama-photon ayizinhlayiya eziyisisekelo eziyi-quanta yokukhanya nazo zonke izinhlobo zemisebe ye-electromagnetic. Ama-photon adlala indima ebalulekile emikhakheni ehlukahlukene yefiziksi, kusukela ku-quantum mechanics kuya ku-optics kanye nobuchwepheshe bolwazi. Lesi sihloko sizoxoxa ngomqondo wama-photon, umlando wawo wokutholwa, izakhiwo eziyisisekelo, kanye nezinhlelo zokusebenza ezahlukahlukene ezisebenzisa ama-photon kwisayensi nobuchwepheshe. Umlando Wokutholwa… Funda kabanzi

I-Relativistic Mass, Momentum, kanye Namandla Isingeniso Umbono okhethekile ka-Albert Einstein wokuhlobana ngo-1905 washintsha ngokuyisisekelo indlela esiqonda ngayo imiqondo ye-mass, momentum, kanye namandla. Ngaphakathi kohlaka lwe-relativity ekhethekile, le miqondo ayisaphelele, njengase-Newtonian physics, kodwa incike ejubaneni elihlobene lento uma iqhathaniswa nombukeli. Lesi sihloko sizoxoxa… Funda kabanzi

Izincazelo Zobudlelwano Obukhethekile Isingeniso Ekuqaleni kwekhulu lama-20, u-Albert Einstein wethula inkolelo-mbono ekhethekile yokuhlobana, eyashintsha ukuqonda kwethu isikhala, isikhathi, kanye nokunyakaza. Le nkolelo-mbono isekelwe ezinhlotsheni ezimbili eziyisisekelo ezaguqula i-physics yakudala futhi zanikeza isisekelo esisha se-physics yanamuhla. Lesi sihloko sizohlola ngokujulile izincazelo ezimbili zokuhlobana okukhethekile, imiphumela yazo ku… Funda kabanzi

Ukuhlolwa KukaMichelson noMorley Isingeniso Ngasekupheleni kwekhulu le-19, umqondo we-ether ekhanyayo, noma nje "i-ether," wawuthandwa kakhulu phakathi kwezazi zefiziksi. I-ether yayikholelwa ukuthi iyindlela engabonakali eyayingena endaweni yonke futhi ihlinzeka ngendlela yokusabalalisa ukukhanya, njengoba nje umoya uhlinzeka ngendlela yamaza omsindo. Ukuhlolwa kukaMichelson noMorley, okwenziwe ngo … Funda kabanzi

Ubudlelwano bukaNewton: Ukuqonda Kwasekuqaleni Kokunyakaza kanye Nokudonsela Kwamandla Isingeniso U-Isaac Newton, omunye wososayensi abanethonya elikhulu emlandweni, wasungula inkolelo-mbono eyashintsha ukuqonda kwethu indawo yonke. Umsebenzi wakhe obalulekile, i-“Philosophiæ Naturalis Principia Mathematica,” eyanyatheliswa ngo-1687, wethula imithetho yokunyakaza kanye nomthetho wamandla adonsela phansi wendawo yonke. Nakuba umqondo wokuhlobene njengoba waziwa kakhulu namuhla uvame ukuhlotshaniswa… Funda kabanzi

Isingeniso Imisebe ye-electromagnetic ingamandla akhishwa futhi asakazwe esikhaleni ngesimo samaza. I-spectrum ye-electromagnetic ihlanganisa izinhlobo ezahlukene zemisebe, kusukela kumaza omsakazo anobude obude kuya emisebeni ye-gamma enobude obufushane kakhulu. Nakuba imisebe ye-electromagnetic inezinzuzo eziningi, njengokuxhumana, ezokwelapha, kanye nasezimbonini, futhi ithwala izingozi ezingaba khona... Funda kabanzi

Isingeniso: Imisebe ye-electromagnetic iyigagasi lamandla asakazeka emkhathini futhi angasebenzisana nezinto. I-spectrum ye-electromagnetic ihlanganisa izinhlobo ezahlukene zemisebe, kusukela kumaza omsakazo kuya emisebeni ye-gamma, ngayinye enamaza ahlukene kanye namaza. Ukusetshenziswa kwemisebe ye-electromagnetic kubanzi, kuhlanganisa amasimu ahlukahlukene njengokuxhumana, ezempilo, imboni, kanye nocwaningo lwesayensi. Lesi sihloko sizobuyekeza… Funda kabanzi
