Ntawd yog, nws yog hnub ntawm Moscow State University chemist. Txij li thaum pib ntawm lub neej, ib qho kev nthuav thiab lom zem kev lig kev cai tshwm sim. Txhua txhua xyoo, lub hnub ntawm chemist yam tsis poob mus nyob rau hauv lub kos npe rau ntawm lub tom ntej no tshuaj keeb kwm, qhia nyob rau hauv lub periodic system ntawm Mendeleev. Ntawd yog, thawj hnub so tau tuav nyob rau hauv lub cim ntawm hydrogen. Los ntawm txoj kev, chemists ua kev zoo siab rau lawv hnub rau hnub Sunday kawg hauv lub Tsib Hlis.

Raws li lub sijhawm ua haujlwm rau hnub so - nws yog lub Tsib Hlis 10, 1965. Xws li yog tsab cai ntawm Presidium ntawm lub Supreme Soviet ntawm lub USSR. Txawm li cas los xij, txawm tias qhov no, thawj tus uas txiav txim siab ua kev zoo siab rau hnub so yog cov neeg los ntawm Kws qhia ntawv ntawm Chemistry ntawm Moscow State University. Tom qab ntawd, lwm lub tsev kawm ntawv tau koom nrog lawv.lub teb chaws. Txawm li cas los xij, vim qee qhov, nws tau tshwm sim tias qee tus ntawm lawv tsis paub hnub Sunday kawg ntawm lub Tsib Hlis ua lawv cov hnub so haujlwm.

Feem ntau, nws tsim nyog sau cia tias ua haujlwm, raws li kev tshawb fawb, chemistry tau tsim xyoo 1961. Nws yog xyoo no uas tus kws tshawb fawb Irish Robert Boyle luam tawm nws phau ntawv The Skeptic Chemist. Lub sijhawm ntawd, nws ua siab tawv heev hauv kev hais tawm nws txoj kev xav txog dab tsi chemistry. Tom qab ntawd Boyle txhais cov chemistry raws li cov txheej txheem ntawm kev kawm txog cov khoom xyaw ntawm txhua yam thiab cov txheej txheem ntawm kev tshawb nrhiav cov ntsiab lus tshiab.

Tab sis thawj zaug lo lus "chemistry" tau qhia los ntawm Roman astronomer Firmicus, thiab nws tshwm sim hauv 336 AD.

Nws tseem tsim nyog sau cia tias hnub ntawm chemist hnub Sunday kawg ntawm lub Tsib Hlis, ntxiv rau Russia, kuj tseem ua kev zoo siab hauv Belarus, Ukraine thiab Kazakhstan.

Hais txog kev ua koob tsheej nws tus kheej, yuav tsum tau muab sau tseg rau nwsLawv sim npaj tiag tiag rau hnub so kev tshaj lij ntawm kws tshuaj - cov no yog cov xwm txheej nthuav, kev sib tw, kev ua si. Tsis tas li ntawd nrov heev nyob rau hnub ntawm tus kws tshuaj yog kev zoo siab uas muaj xim lom zem. Zoo, thiab raws li tau sau tseg saum toj no, txhua txhua xyoo hnub no dhau los ntawm lub cim ntawm ib qho ntawm cov tshuaj hais qhia nyob rau hauv lub sij hawm system, yog li tag nrho cov hnub caiv "revolves" precisely nyob rau hauv lub tom ntej no lub caij. Nyob rau hauv ib txoj kev, qhov no yog reminiscent ntawm kev ua koob tsheej ntawm lub xyoo tshiab nyob rau hauv lub cim ntawm ib yam tsiaj.
