Sihloko: Isayensi
Umsunguli u-Elon Musk usesuse isikhala semidiya kuma-cryptocurrencies kanye nepolitiki yomhlaba. Ngokukhipha imibono eyishumi ngosuku, usozigidi waseMelika uthathe ukunaka kwabantu bomhlaba. Efuna ukonga imali ekuqalisweni kwamarokhethi, uMusk ufuna ukusungula izinto ezintsha. Usozigidi wabiza owakhe umqondo ngokuhlanya, kodwa wathatha izibalo ezingokoqobo. Eqinisweni, ukuphepha kwesiteji esiphezulu se-jet injini kusuka ku-orbit kubukeka njengomsebenzi ongaxazululeka ngokuphelele. Ingxenye yomkhumbi-mkhathi ibuyela Emhlabeni noma kunjalo. Kusele ukuthi u-Elon Musk abambe futhi alethe isigaba sesibili endaweni edingekayo. Ingabe imibono ka-Elon Musk iyahlanya? Ibhaluni! Uzwe kahle - ibhaluni lephathi elikhulu lizosiza ukufeza iphrojekthi yebhiliyoni yaseMelika. Kuyaphawuleka ukuthi umqondo wafika ...

I-Large Hadron Collider yawa ezindabeni futhi abasebenzisi be-inthanethi bakhohlwa ngokuba khona kokufakwa. Futhi akumangazi, ngoba njalo ebusika, i-LHC iya ukugcinwa nokuthuthukiswa. Ukuze ujabulise umhlaba wesayensi ngokutholwa okusha emkhakheni we-physics entwasahlobo. Umhla zingama-30 kuNdasa umaka iminyaka eyisikhombisa ncamashi selokhu i-LHC isiza abacwaningi ukuthi bafunde ngokuvela kwendawo yonke kanye nezinqubo zamandla ezihlobene. Ukugijima kwamaviki amabili kubonise ukuthi iyunithi isilungele ukusebenza futhi ayidingi ukuxazululwa inkinga. Ososayensi bahlole amasistimu okupholisa ama-cryogenic, ama-resonators e-RF, odonsa, imithombo yamandla eyengeziwe, futhi baqinisekisa ukuthi i-LHC isilungele imisebenzi emisha. I-Large Hadron Collider isilungele ucwaningo Akukaziwa ukuthi yini le ...

Ngemva kokuthola ubudlelwano phakathi kokugijima nokuthuthukisa inkumbulo, abacwaningi abavela kuwo wonke umhlaba baphuthuma ukuyofunda ubuchopho bomuntu nokuthi inkumbulo isebenza kanjani. AbaseBrithani beza kuqala. Ukuvuselela inkumbulo kagesi we-transcranial ngesikhathi sokulala, ngokusho kososayensi baseBrithani, kungathuthukisa ukukhumbula. Eziphethweni ezinjalo, abacwaningi baseYunivesithi yaseYork bafika ngemva kokuhlolwa kwesayensi. Ososayensi bashicilele eyabo imiphumela ngoMashi 9, 2018 kujenali Current Biology. Ososayensi bathole indlela entsha yokuthuthukisa inkumbulo Ucwaningo lwenziwa ngezinsimbi zokulala - ukuqhuma kobuchopho oscillations kubonise ukuxhumana phakathi kokukhumbula ulwazi nokulala. Amavolontiya, ekuhlolweni, atshelwe izichasiso nezinhlangano ezixhumene nazo. Lapho umuntu esozela, abacwaningi basho izichasiso futhi, ...
