Eli nqaku liye lahlaziywa ngokuhambelana nenkqubo yokuhlela kunye nomgaqo-nkqubo weSayensi X. Abahleli bagxininise ezi mpawu zilandelayo ngelixa beqinisekisa ukuba umxholo uchanekile:
Iingcali zeMathematika kwiiDyunivesithi zaseYorkshire, eCambridge, eWaterloo naseArkansas zizenze zagqibelela ngokufumana isihlobo esisondeleyo “somnqwazi,” imilo yejiyometri ekhethekileyo engaphindiyo xa ifakwe ithayile, oko kukuthi, i-chirality yokwenene i-aperiodic monolith. UDavid Smith, uJoseph Samuel Myers, uCraig Kaplan, kunye noChaim Goodman-Strauss bapapashe inqaku elichaza iziphumo zabo ezintsha kwi-arXiv preprint server.
Kwiinyanga nje ezintathu ezidlulileyo, iingcali zezibalo ezine zabhengeza oko kwaziwa endle njengefom ye-Einstein, ekuphela kwefom enokusetyenziswa yodwa kwi-non-periodic tileng. Bayibiza ngokuthi "umnqwazi".
Ukufumanisa kubonakala kuyisinyathelo samva nje kwi-60-year search for form. Iinzame zangaphambili zibangele iziphumo zeebhloko ezininzi, eziye zancitshiswa kuphela ezimbini phakathi kwe-1970s. Kodwa ukususela ngoko, iinzame zokufumana imilo ye-Einstein ayiphumelelanga - kude kube ngoMatshi, xa iqela elisebenza kwiprojekthi entsha libhengeze oku.
Kodwa abanye babonisa ukuba ubuchwephesha ubume obuchazwa ngumyalelo awukho ithayile enye ye-aperiodic-yona kunye nomfanekiso wayo wesibuko ziithayile ezimbini ezizodwa, nganye inoxanduva lokudala imilo umyalelo ochazayo. Ebonakala evumelana novavanyo lwabalingane babo, izazi zezibalo ezine zayihlaziya indlela yazo zaza zafumanisa ukuba emva kohlengahlengiso oluncinane, isipili sasingasafuneki yaye ngokwenene sasimele uhlobo lokwenyaniso lukaEinstein.
Kuyafaneleka ukuba uqaphele ukuba igama elisetyenziselwa ukuchaza imilo alikho inkokhelo kwi-physicist eyaziwayo, kodwa livela kwibinzana lesiJamani elithetha "ilitye". Iqela liyibiza iyunifomu entsha nje ngokuba sisihlobo esisondeleyo somnqwazi. Bakwaqaphele ukuba ukutshintsha imiphetho yeepolygoni ezisanda kufunyanwa ngendlela ethile kukhokelele ekudalweni kweseti epheleleyo yeemilo ezibizwa ngokuba yiSpectra, zonke ezizii-chiral aperiodic monoliths ngokungqongqo.

Ingxelo yakho ibaluleke kakhulu kuthi. Nangona kunjalo, ngenxa yomthamo wemiyalezo, asinakuqinisekisa iimpendulo zomntu ngamnye.
Idilesi yakho ye-imeyile isetyenziselwa kuphela ukwazisa abamkeli ukuba ngubani othumele i-imeyile. Idilesi yakho okanye idilesi yomamkeli ayisayi kusetyenziselwa nayiphi na enye injongo. Ulwazi olufakileyo luya kuvela kwi-imeyile yakho kwaye aluyi kugcinwa yiPhys.org nangaluphi na uhlobo.
