Lesi sihloko sibuyekeziwe ngokuvumelana nenqubo yokuhlela kanye nenqubomgomo ye-Science X. Abahleli bagcizelele izici ezilandelayo kuyilapho beqinisekisa ukuthi okuqukethwe kunembile:
Izazi zezibalo zamaNyuvesi aseYorkshire, eCambridge, eWaterloo, nase-Arkansas zizenze zaba zinhle ngokuthola isihlobo esiseduze “sesigqoko,” umumo wejiyomethri oyingqayizivele ongaphindi lapho ufakwe amathayela, okungukuthi, i-chirality yangempela ye-aperiodic monolith. UDavid Smith, uJoseph Samuel Myers, uCraig Kaplan, kanye noChaim Goodman-Strauss bashicilele indatshana echaza abakutholile okusha kuseva yokuphrinta ye-arXiv.
Ezinyangeni ezintathu nje ezedlule, izazi zezibalo ezine zamemezela lokho okwaziwa emkhakheni njengefomu le-Einstein, okuwukuphela kwefomu elingasetshenziswa lodwa ekufakweni kwamathayela okungewona wezikhathi ezithile. Bayibiza ngokuthi “isigqoko”.
Ukutholwa kubonakala kuyisinyathelo sakamuva ocwaningweni lweminyaka engama-60 lwefomu. Imizamo yangaphambilini iholele emiphumeleni yamabhulokhi amaningi, eyancishiswa yaba kabili phakathi nawo-1970. Kodwa kusukela ngaleso sikhathi, imizamo yokuthola isimo sika-Einstein ayizange iphumelele - kuze kube ngoMashi, lapho ithimba elisebenza kuphrojekthi entsha limemezela lokhu.
Kodwa abanye baveza ukuthi ngokobuchwepheshe umumo ochazwa umyalo awulona ithayela elilodwa le-aperiodic—lona kanye nesibuko salo kungamathayela amabili ahlukile, ngalinye linesibopho sokudala isimo esichazwa umyalo. Ngokubonakala bevumelana nokuhlola kozakwabo, izazi zezibalo ezine zabuyekeza isimo sazo futhi zathola ukuthi ngemva kokuguqulwa okuncane, isibuko sasingasadingeki futhi ngempela simelela isimo sangempela sika-Einstein.
Kuyaphawuleka ukuthi igama elisetshenziselwa ukuchaza ukuma akuyona inkokhiso kusazi sesayensi yemvelo esidumile, kodwa livela egameni lesiJalimane elisho "itshe". Iqembu libiza umfaniswano omusha nje ngesihlobo esiseduze sesigqoko. Baphinde baphawula ukuthi ukushintsha imiphetho yamapholigoni asanda kutholwa ngendlela ethile kuholele ekudalweni kwayo yonke isethi yomumo ebizwa ngokuthi i-Spectra, konke okuyi-chiral aperiodic monoliths.

Uma uhlangabezana nephutha lokuthayipha, ukunemba, noma ungathanda ukuhambisa isicelo sokuhlela okuqukethwe kwaleli khasi, sicela usebenzise leli fomu. Ngemibuzo ejwayelekile, sicela usebenzise ifomu lethu lokuxhumana. Ukuze uthole impendulo evamile, sicela usebenzise isigaba sokuphawula komphakathi esingezansi (izincomo sicela).
Impendulo yakho ibaluleke kakhulu kithi. Nokho, ngenxa yobuningi bemilayezo, asikwazi ukuqinisekisa izimpendulo ngazinye.
Ikheli lakho le-imeyili lisetshenziselwa ukwazisa abamukeli kuphela ukuthi ngubani othumele i-imeyili. Ikheli lakho noma ikheli lomamukeli ngeke lisetshenziselwe enye injongo. Ulwazi olufakile luzovela ku-imeyili yakho futhi ngeke lugcinwe yi-Phys.org nganoma iyiphi indlela.
Thola izibuyekezo zamasonto onke kanye/noma zansuku zonke ebhokisini lakho lokungenayo. Ungazikhipha ohlwini noma nini futhi ngeke sabelane ngedatha yakho nezinkampani zangaphandle.
Le webhusayithi isebenzisa amakhukhi ukwenza lula ukuzulazula, ukuhlaziya ukusebenzisa kwakho amasevisi ethu, ukuqoqa idatha ukuze wenze izikhangiso zibe ngokwakho, futhi inikeze okuqukethwe okuvela kwabanye abantu. Ngokusebenzisa iwebhusayithi yethu, uyavuma ukuthi uyifundile futhi wayiqonda Inqubomgomo yethu Yobumfihlo kanye Nemigomo Yokusebenzisa.
