<prompt> Fingqa isihloko: Umfundi waseBrown University oshona ngemva kokugxuma esitezi se-12 esakhiweni sasekolishi. UHyoun Ju Sohn, umfundi weziqu zobudokotela weminyaka engu-25 ubudala waseNingizimu Korea, washona ngoLwesibili cishe emini ngemva kokuwa esakhiweni seScience Library.

Lo mfundi wayenesithakazelo ngokukhethekile kuyi - physics yezinto ezihlanganisiwe. Isitezi seshumi nambili seBrown Universitys Science Library savalwa ngoLwesibili ntambama. Isisebenzi sabonakala sihlanza iwindi eliphukile ngaphansi. NgoLwesibili ebusuku kwabanjwa umlindelo wabantu abangu-350 ngaphandle kwesikhungo sekhampasi, futhi kwabanjwa imihlangano emincane yabafundi nabafundisi.
