Astrophysics vs Astronomy
Astronomy thiab astrophysics yog kev tshawb fawb txog lub cev xilethi-aus. Cov no yog qee qhov kev tshawb fawb qub tshaj plaws ntawm txhua lub sijhawm. Ob yam no suab yuav luag tib yam. Tab sis peb yuav pom tias ob yam no yeej txawv ntawm ib leeg. Kab lus no yog hais txog keeb kwm ntawm astronomy thiab astrophysics, lawv txoj kev kawm, qhov zoo sib xws ntawm astronomy thiab astrophysics thiab qhov txawv ntawm astronomy thiab astrophysics.
Astronomy
Astronomy yog ib qho kev kawm loj. Nws yog ib tug natural science. Astronomy yog kev tshawb fawb ntawm kev kawm cov khoom thiab qhov tshwm sim uas tshwm sim sab nraum lub ntiaj teb huab cua. Txoj kev tshawb no suav nrog physics ntawm stellar lub cev, tsim ntawm lub ntiaj teb, evolution ntawm lub ntiaj teb, chemistry ntawm celestial lub cev, meteorology ntawm celestial lub cev thiab kev txav ntawm cov khoom no. Cov khoom kawm nyob rau hauv astronomy muaj xws li hnub qub, ntiaj chaw, satellites, nebulae, galaxies, hnub qub pawg, galaxy pawg, comets thiab phenomena xws li cosmic keeb kwm yav dhau hluav taws xob thiab liab hloov los yog xiav hloov ntawm cov khoom. Astronomy yog suav hais tias yog qhov kev tshawb fawb qub tshaj plaws. Muaj pov thawj ntawm ancient kab lis kev cai tau kawm astronomy. Kev vam meej xws li Greek, Babylonian, Suav, Khab thiab Mayan tau tso tseg cov pov thawj txaus los txhawb txoj kev xav saum toj no. Great pyramids, Stonehenge thiab Nubian monuments yog rau npe ob peb. Astronomy muaj ob lub ntsiab lus tseem ceeb, theoretical astronomy thiab observational astronomy. Theoretical astronomy yog cov txheej txheem ntawm kev xav raws li cov qauv ntawm lub ntiaj teb tau muab tso rau pem hauv ntej. Cov kev xav no yog cov kev xav dawb huv ntawm cov kws tshawb fawb lossis cov qauv hauv computer raws li cov kev xav tau lees paub yav dhau los. Observational astronomy yog ib ceg ntawm astronomy uas tau txais cov ntaub ntawv los ntawm cov khoom siv xws li telescopes, xov tooj cua telescope arrays lossis spectrometers thiab txheeb xyuas lawv kom tuaj nrog tus qauv tshiab lossis txhawb lossis tawm tsam tus qauv uas twb muaj lawm. Ob leeg theoretical thiab kev soj ntsuam cov ceg tseem ceeb sib npaug rau kev nce qib ntawm astronomy.
Astrophysics
Txawm hais tias astronomy yog ib qho kev kawm thaum ub, nws tau raug suav hais tias yog ib qho kev kawm philosophical, thiab tau muab faib los ntawm lwm yam kev tshawb fawb ntuj suav nrog physics. Astrophysics yog ib lo lus raws li Greek. Hauv Greek "astro" txhais tau tias lub hnub qub thiab "physis" txhais tau tias xwm. Astrophysics txhais tau tias qhov xwm ntawm cov hnub qub. Nws tuaj yeem raug coj los ua kev kawm txog kev txav thiab kev coj cwj pwm ntawm cov khoom stellar. Raws li astrophysics yog ib qho kev kawm dav heev, nws yuav tsum muaj kev paub txog thaj chaw xws li electromagnetic theory, mechanics, statistical mechanics, thermodynamics quantum mechanics, relativity, nuclear physics thiab particle physics. Txoj kev tshawb no ntawm astrophysics suav nrog ntsuas cov khoom xws li tshuaj lom neeg muaj pes tsawg leeg, qhov ntom ntom, qhov loj, luminosity thiab qhov kub thiab txias ntawm cov khoom stellar thiab siv lawv los ua qauv thiab kwv yees seb lub cev stellar yuav coj li cas.
Dab tsi yog qhov txawv ntawm astronomy thiab astrophysics?
– Astronomy yog kev kawm txog tag nrho cov peev txheej ntawm lub cev xilethi-aus, lawv tus cwj pwm, lawv lub hauv paus, kev soj ntsuam thiab txawm tias daim duab hnub qub yooj yim.
– Astrophysics tsuas yog kawm txog thaj tsam ntawm physics ntawm cov khoom ntuj ceeb tsheej thiab cov tshuab.
– Thaum astronomy raws li ib qho kev kawm tseem qub, astrophysics yog qhov tshiab.
– Astrophysics tiag tiag yog ib ceg ntawm astronomy, uas kawm txog physics ntawm "astro" lub cev.
