Cov kws tshawb fawb pom tias cov kws txawj ua txuj ci, txog li 2,000 xyoo dhau los (los ntawm kev yos hav zoov), siv qee cov cuab yeej siv thaum ub los siv cov yeeb yaj kiab ntawm cov hlau rau cov duab thiab lwm yam khoom uas tau dhau los ntawm cov qauv niaj hnub no rau kev tsim cov DVDs, hnub ci vaj huam sib luag, cov khoom siv hluav taws xob thiab. lwm yam khoom.

Qhov kev tshawb pom txawv txawv no, luam tawm nyob rau hauv phau ntawv Journal Accounts of Chemical Research, taw qhia rau "cov neeg txawj ntse ntawm cov neeg txawj ntse ntawm lub sijhawm qub, uas muaj peev xwm tsim tau cov khoom zoo li no uas tsis tuaj yeem dhau ntawm cov hnub ntawd, thiab niaj hnub no. thev naus laus zis tseem tsis tau ua tiav," lawv sau cov kws tshawb fawb los ntawm American Chemical Society, coj los ntawm Gabriel Maria Ingo, uas ua qhov kev tshawb pom no.

Gilding thiab silvering yog cov txheej txheem ntev-paub raws li kev siv mercury, thiab tau siv nyob rau hauv ancient sij hawm los npog cov khoom xws li hniav nyiaj hniav kub, pej thuam thiab amulets nrog nyias txheej ntawm kub los yog nyiaj. Txawm hais tias lawv feem ntau siv rau kev kho kom zoo nkauj, qee zaum lawv tau siv los dag ntxias kom muab qhov zoo li kub lossis nyiaj rau cov hlau tsis tshua muaj nqi.

Los ntawm cov tswv yim thev naus laus zis, cov kws ua haujlwm qub 2,000 xyoo dhau los qee qhov kev tswj hwm los ua cov txheej txheem hlau no zoo kawg nkaus nyias, nruj-haum thiab ua txhua yam hauv qee yam tsis paub, uas ua rau nws muaj peev xwm txuag tau cov hlau muaj txiaj ntsig thiab txhim kho lawv cov kav ntev - thiab peb niaj hnub. thev naus laus zis tseem tsis tau muaj peev xwm mus txog qhov zoo li no.

Obviously, tsis muaj kev paub txog cov txheej txheem tshuaj-lub cev, cov neeg ua haujlwm qub qub tau tswj hwm cov hlau kom tau txais txiaj ntsig zoo tshaj plaws. Lawv tau tsim ntau yam txuj ci uas siv cov mercury ua ib qho nplaum rau cov khoom siv nrog nyias zaj duab xis ntawm cov hlau muaj txiaj ntsig.

Qhov kev tshawb pom no qhia tau hais tias nyob rau hauv ancient sij hawm, nyob rau hauv tej yam tsis paub, tib neeg muaj kev nkag siab zoo heev ntawm cov txheej txheem thev naus laus zis thiab cov txheej txheem uas tseem tsis tuaj yeem piav qhia nrog qib ntawm cov ntaub ntawv peb muaj. Lwm qhov piv txwv ntawm cov thev naus laus zis thaum ub yog lub npe nrov Antikythera Mechanism 2000 xyoo - cov cuab yeej hlau ua los ntawm kev sib xyaw ua ke ntawm lub zog, uas, raws li cov kws tshawb fawb, tau siv los suav cov haujlwm ntawm lub cev xilethi-aus.
