Tsim, Zaj dabneeg
Leej twg invented lub qhov muag teev, thiab leej twg nkag tau nws nyob rau hauv peb lub neej?
Niaj hnub no peb lub neej kev nplij siab ensured vim lub nplua mais ntawm kev khoom thiab ib tug ntau yam ntawm khoom vaj khoom tsev, tsis muaj uas peb twb tsis yooj yim rau kev tswj. Peb coj lawv nyob rau qib subconscious, tsis xav txog yuav ua li cas lawv ua hauj lwm, uas yog lawv inventor. Tus txiv neej los ntawm qhov yog yeej ib txwm mob siab rau ntau dua, nws muaj ambitious npaj systematically kov yeej tag nrho los xij. Piv txwv ntawm yuav ua li cas cov neeg no tsis nco qab txog lub teeb meem, strove rau pem hauv ntej txaus.
Txawm li cas los, peb yuav tsum tsis txhob hnov qab txog nws yav dhau los, qhov ntau thiaj li muaj ntau ntawm cov piv txwv uas tej zaum yuav pab tau tam sim no. Ces muaj ntau heev cov paub tab, nws yuav zoo li ntau yooj yim thiab elementary, tab sis xav txog tej yam yog hais tias nws tsis yog ib tug dog dig qhov muag teev, raws li yog hais tias peb tau nyob tam sim no? Peb tej zaum yuav tsis xav txog niaj hnub siv tshuab, qhov chaw sib ntaus thiab haib computers, thiab yog tseem sim mus nrhiav kom tau koj tus kheej lub neej, yog hais tias koj tsis nco qab uas yees ua lub teeb teeb.
Peb accustomed mus rau tus cwj pwm cov invention rau tej tus neeg, tab sis yog tej zaum qhov tshwm sim ntawm ib tug kev sib koom tes dag zog ntawm ib tug loj tus naj npawb ntawm cov neeg, tab sis, rau piv txwv, uas yees ua lub teeb qhov muag teev, uas tam sim no yog nyob rau hauv txhua txhua lub tsev?
Teeb nyob rau hauv txhua txhua lub tsev
Koj yuav tsum to taub tias tsis muaj lub teeb hais tias cov neeg yuav tsis ua neej nyob, yog li txhua yam yuav tuaj nrog ib yam dab tsi los taws lawv cov tsev. Nyob rau hauv lub feem ntau ancient lub sij hawm siv cov hluav taws kub, qhov txos thiab fireplaces, ces siv ib tug tswm ciab. Tab sis txoj kev siv cov nyob hluav taws yog ib tug xov tooj ntawm inconveniences thiab txawm ib co kev txaus ntshai.
Nyob rau hauv antiquity, siv av nplaum huam sau nrog txiv roj roj thiab ib lub paj rwb wick. Tom qab ntawd lub Caspian ntug dej hiav txwv siv zoo xws li cov teeb, tsuas yog siv raws li roj roj. Incidentally, tus thawj ciab taws tswm ciab muaj nyob xwb nyob rau hauv cov Nrab Hnub nyoog thiab raug xam tias yog sufficiently tseem ceeb invention rau nws lub sij hawm.
Tom qab ntawd, nrog txoj kev loj hlob ntawm science, muaj ntau zaum muaj tej yam nyuaj yuav daws tau qhov teeb meem no. Ib tug ntawm lawv yog Leonardo da Vinci uas coj cov ntau yam tswv yim nyob rau hauv science. Nws, dhau lawm, muaj peev xwm yuav tej xam raws li cov neeg uas invented thawj qhov muag teev. Txawm hais tias nws yog ib tug kerosene teeb, nws cia li ua neeg dawb huv uas twb muaj lawm tswv yim. Tab sis qhov teeb meem tseem nyob li qub - ib qhib nplaim taws nyob ze ntawm lub roj muaj peev xwm, nyob rau hauv qhov tseeb, ua nws nrog Molotov cocktails.
qhov muag teev
Raws li twb hais saum toj no, cov invention qhov muag teev - nws yog ib tug ntev txoj kev ua hauj lwm. Nyob rau hauv lub xyoo pua puv 19 tuaj thawj tsab ntawm ib tug ruaj ntseg teeb pom kev zoo ntaus ntawv. Nws puas tau Lavxias teb sab hluav taws xob engineer thiab paub txog Pavel Nikolaevich Yablochkov. Nws Yablochkov - ib tug uas yees ua lub teeb teeb. Tsis tas li ntawd mus rau nws lub credit thiab cov thawj hluav taws xob tswm ciab. Nws tsim tau muaj ntau lub drawbacks, ua ntej ntawm tag nrho cov, ib tug tsis ruaj tsis khov teeb tso zis thiab tsis tshua muaj lub neej. Tab sis, cuaj kaum, lawv tau siv nyob rau hauv loj tus xov tooj rau txoj kev teeb pom kev zoo, raws li zoo li ib qho tseem ceeb cov khoom Zog ntawm Guj kuj: theaters, khw, central squares, etc.
Txawm li cas los, nyob rau hauv kev ncaj ncees nws yuav tsum tau muab sau tseg tias lo lus nug ntawm uas yees ua lub teeb qhov muag teev, nws yog tsis yooj yim sua rau lub npe tsuas yog ib lub npe. Tom qab tag nrho, tus ntaus ntawv nws tus kheej tau tuaj ib tug ntev txoj kev evolution. Nyob rau hauv lub sij hawm ntawm 1840 mus 1870. Muaj ntau zaum tau ua hauj lwm los tsim zoo hluav taws xob teeb pom kev zoo, tab sis qhov tshwm sim yog tsis mus txog rau thaum nyob rau hauv 1872 lub Lavxias teb sab engineer Aleksandru Lodyginu tsis muaj hmoo. Nws yog ib tug uas yees ua lub incandescent teeb. Twb tau nyob rau 1873 nyob rau hauv txoj kev ntawm St. Petersburg ob Lodygina qhov muag teev.
Cov ua tau lub npe hu American paub txog Thomas Edison. Nws siv Lodygina tsim tau, thiab sim los txhim kho nws, txiav txim siab nrog tus durability teeb meem. Nws thaum kawg pom txoj cai muaj pes tsawg leeg ntawm carbon filament, uas tso cai rau lub teeb mus hlawv ib tug ob peb puas teev. Nws kuj yuav ntaus nqi mus rau inventors ntawm lub teeb, tab sis nws tsis ua hauj lwm nyob rau hauv kev txhim kho, sib txuas sib txawv kev tshawb fawb zaum twb.
