xov xwm

Kab lus no tau raug tshuaj xyuas raws li cov txheej txheem kho thiab Science X txoj cai. Cov kws kho mob tau hais txog cov cwj pwm hauv qab no thaum ua kom cov ntsiab lus raug:
Cov kws ua lej hauv University of Yorkshire, Cambridge, Waterloo, thiab Arkansas tau ua tiav lawv tus kheej los ntawm kev nrhiav ib tus txheeb ze ze ntawm "lub kaus mom," ib qho duab geometric tshwj xeeb uas tsis rov ua dua thaum pobzeb, uas yog, qhov tseeb chirality aperiodic monolith. David Smith, Joseph Samuel Myers, Craig Kaplan, thiab Chaim Goodman-Strauss tau luam tawm ib tsab xov xwm qhia txog lawv qhov kev tshawb pom tshiab ntawm arXiv preprint server.
Tsuas yog peb lub hlis dhau los, plaub tus lej lej tau tshaj tawm qhov paub hauv daim teb raws li Einstein daim ntawv, tsuas yog daim ntawv uas siv tau ib leeg rau kev sib tsoo tsis yog lub sijhawm. Lawv hu nws "lub kaus mom".
Qhov kev tshawb pom zoo li yog cov kauj ruam kawg hauv kev tshawb nrhiav 60 xyoo rau daim ntawv. Cov kev siv zog yav dhau los ua rau muaj ntau qhov kev cuam tshuam, uas tsuas yog txo qis rau ob zaug hauv nruab nrab xyoo 1970s. Tab sis txij thaum ntawd los, kev sim nrhiav cov duab ntawm Einstein tau ua tsis tiav - txog lub Peb Hlis, thaum pab pawg ua haujlwm ntawm qhov project tshiab tshaj tawm qhov no.
Tab sis lwm tus taw qhia tias technically cov duab cov lus txib piav qhia tsis yog ib lub pobzeb aperiodic - nws thiab nws daim iav daim iav yog ob lub pobzeb tshwj xeeb, txhua lub luag haujlwm tsim cov duab cov lus txib piav qhia. Zoo li pom zoo nrog lawv cov npoj yaig kev ntsuam xyuas, plaub tus lej lej tau hloov kho lawv daim ntawv thiab pom tias tom qab hloov kho me ntsis, daim iav tsis xav tau ntxiv lawm thiab qhov tseeb sawv cev Einstein daim ntawv tseeb.
Nws yog tsim nyog sau cia tias lub npe siv los piav txog cov duab tsis yog khoom plig rau lub npe nrov physicist, tab sis los ntawm cov lus German lub ntsiab lus "pob zeb". Pab neeg hu cov khaub ncaws tshiab tsuas yog cov txheeb ze ze ntawm lub kaus mom. Lawv kuj tau sau tseg tias kev hloov pauv ntawm cov npoo ntawm cov polygons uas nyuam qhuav pom nyob rau hauv ib txoj kev coj mus rau kev tsim ntawm tag nrho cov duab hu ua Spectra, tag nrho cov uas yog nruj me ntsis chiral aperiodic monoliths.

Yog tias koj ntsib qhov typo, tsis raug, lossis xav xa daim ntawv thov los hloov cov ntsiab lus ntawm nplooj ntawv no, thov siv daim foos no. Rau cov lus nug dav dav, thov siv peb daim foos tiv tauj. Rau kev tawm tswv yim dav dav, thov siv cov lus qhia pej xeem hauv qab no (cov lus pom zoo thov).
Koj cov lus teb tseem ceeb heev rau peb. Txawm li cas los xij, vim qhov ntim ntawm cov lus, peb tsis tuaj yeem lav cov lus teb rau tus kheej.
Koj tus email chaw nyob tsuas yog siv los qhia rau cov neeg tau txais kev paub tias leej twg xa email. Tsis yog koj qhov chaw nyob lossis tus neeg txais qhov chaw nyob yuav tsis raug siv rau lwm lub hom phiaj. Cov ntaub ntawv koj tau nkag mus yuav tshwm sim hauv koj tus email thiab yuav tsis muab khaws cia los ntawm Phys.org hauv ib daim ntawv.
Tau txais cov hloov tshiab txhua lub lim tiam thiab / lossis txhua hnub hauv koj lub inbox. Koj tuaj yeem tso npe tau txhua lub sijhawm thiab peb yuav tsis qhia koj cov ntaub ntawv rau peb tog.
Lub vev xaib no siv cov ncuav qab zib los pab txhawb kev taug kev, txheeb xyuas koj qhov kev siv peb cov kev pabcuam, sau cov ntaub ntawv los ua tus kheej tshaj tawm, thiab muab cov ntsiab lus los ntawm peb tog. Los ntawm kev siv peb lub vev xaib, koj lees paub tias koj tau nyeem thiab nkag siab peb Txoj Cai Tswjfwm Ntiag Tug thiab Cov Cai Siv.
