I ka makahiki 1950, ua ʻike nā physicists ʻo George Gamow lāua ʻo Marvin Stern i kahi mea hoihoi: ʻo Gamow, nona kahi keʻena ma ka papahele mua o kahi hale ʻeono papa, ʻike ʻo ia he ʻelima o nā manawa ʻeono i hiki mai i lalo, ʻoiai makemake ʻo ia. e piʻi i luna. Ua nānā ʻo Stern, nāna i hana ma ka papahele ʻelima.
ʻO ka mea maʻamau ke hele mai ka elevator mai kahi papahele o luna a iho i lalo i kona makemake e iho i lalo. I loko o kahi hale papa nui, ʻike pinepine ʻia ka elevator e hiki mai ana ma kahi ʻē aʻe ma mua o kou manaʻo. Aia ka wehewehe ʻana o ka hanana i ka manawa like ʻole e hoʻohana ai nā elevators ma nā papahele like ʻole.
Ma nā papahele haʻahaʻa, ʻoi aku ka nui o ka piʻi ʻana o ka elevator hou no ka mea ʻoi aku ka pōkole o ka manawa hele i lalo ma mua o ka manawa piʻi. Ma nā papahele kiʻekiʻe, ua hoʻohuli ʻia ke kūlana: Ma ʻaneʻi ʻoi aku ka kiʻekiʻe o ka piʻi ʻana o ka ʻeleke aʻe no ka mea ʻoi aku ka lōʻihi o ka manawa hele i lalo a hoʻi.
Inā ʻoe ma ka papahele kiʻekiʻe o kahi hale, hele mai nā elevators a pau mai lalo mai (ʻaʻohe mea hiki ke hele mai mai luna mai) a laila iho i lalo, ʻoiai ma ka papahele penultimate, hele mua kahi elevator i ka papahele kiʻekiʻe a ma hope koke iho e hala ana ma lalo - no laila ʻoiai ka helu like o nā elevators e hele ana ma ke piʻi ʻana me ke iho ʻana, ʻo nā elevators e iho ana ma hope o nā elevators e piʻi ana ma hope koke iho, a no laila ʻo ka elevator mua i ʻike ʻia e piʻi pinepine ana.
E iho ana ka elevator i ike mua ia ina e hoomaka ana kekahi e nana i ka manawa pokole mahope iho o ka hala ana o ka eleekee iluna, a o ke koena o ka manawa e pii ai ka elevator ike mua ia.
Hoʻohana ka elevator hoʻokahi i ka hapa nui o kona manawa ma ka hapa nui o ka hale a no laila e hele mai ana mai kēlā ala ke hiki mai ka mea hoʻohana elevator. ʻO ka mea nānā i noho ma nā puka ʻeleʻele no nā hola a i ʻole nā lā, e nānā ana i kēlā me kēia elevator e hōʻea, ma mua o ka nānā wale ʻana i ka elevator mua , e ʻike ʻo ia aia ka helu like o nā elevators e hele ana i kēlā me kēia ʻaoʻao.
Pehea mākou e ʻike ai he like ka helu o nā elevators ma kēlā me kēia ʻaoʻao? Hana ʻia kēia ma ka mālama ʻana i nā elevators . Inā, i kekahi manawa, ʻoi aku ka nui o nā elevators e piʻi ana ma mua o ka iho ʻana, e emi mau ana ka helu o nā elevators ma lalo o kēlā kiko, ʻaʻole hiki.
