Ib qho tseem ceeb tshaj qhov cuam tshuam ntawm symmetry inphysics yog lub hav zoov ntawm kev txuag txoj cai. Rau txhua lub ntiaj teb txuas ntxiv symmetry -i.e., ib qho kev hloov ntawm aphysical system uas ua tib yam li txhua qhov chaw thiab txhua lub sijhawm - muaj ib qho kev cuam tshuam rau lub sijhawm ywj pheej kom muaj nuj nqis: aconserved charge.

Tsis tas li ntawd, vim li cas symmetry tseem ceeb hauv physics?

Nws yog ib qho kev nthuav dav ntawm txoj kev xav ntawm ib qho kev sib npaug, thiab koj tuaj yeem siv nws los muab qhov sib npaug. Symmetries yog immensely tseem ceeb vim txhua symmetry tuaj yeem hais tau raws li txoj cai kev txuag. Cov nyhuv no, vim yog Noether's theorem, tso cai rau koj kom pom cov kev cai tseem ceeb ntawm lub ntiaj teb.

Tsis tas li ntawd, vim li cas symmetry yog qhov tseem ceeb hauv lub neej niaj hnub? Symmetry yog ib yam uas peb saib nyob rau hauv ntau qhov chaw hauv peb lub neej txhua hnub txawm tsis pom nws. Nws yooj yim pom nyob rau hauv ntau yam txuj ci, vaj tse, thiab monuments. Natureuses symmetry ua tej yam zoo nkauj. Vim symmetry ib yam khoom, duab thiab saib zoo nkauj dua.

Ib yam li ib tug yuav nug, lub ntsiab lus ntawm symmetry hauv physics yog dab tsi?

Hauv physics , a symmetry ntawm lub cev lub cev yog lub cev lossis kev ua lej ntawm lub cev (saib lossis qhov tseeb) uas tau khaws cia lossis tseem tsis hloov pauv hauv qee qhov kev hloov pauv.

Peb kawm dab tsi los ntawm symmetry?

Vim tib neeg lub cev muaj "kev xav symmetry , "Spotting pab tus neeg seev cev kom nws sib npaug. Los ntawm lub cev thiab kev xav ntawm kev seev cev, menyuam yaus kawm kom pom cov qauv thiab sim lawv qhov kev nkag siab. Qhov no ua haujlwm nrog cov qauv lej ib yam. Ntau tus menyuam yaus ntseeg tias qhov sib npaug txhais tau tias "cov lus teb."
