Thaum kawg ntawm lub xyoo pua 19th, Crystal Palace hauv Hyde Park tau tuav lub ntiaj teb kev lag luam exhibition, qhov twg tag nrho cov thev naus laus zis tau nthuav tawm. Ib qho tshwj xeeb ntawm kev nthuav qhia yog wireless hluav taws xob tsim …

Exhibition, qhov twg thawj zaug "tshuab tau koom ua ke"

Hyde Park yog thawj zaug tua tsiaj rau tsev neeg muaj koob muaj npe, thiab tsis yog txog rau xyoo pua 17th uas nws tau qhib rau pej xeem. Thaum xyoo 1840 lub Tsev Hais Plaub tau txais 2 lub tswv yim los npaj cov rooj sib tham hauv Hyde Park txhua xyoo, lawv tau "tsis lees paub" vim tias muaj kev nyab xeeb rau pej xeem - vim tias lawv yuav yog lub hauv paus ntawm kev kub ntxhov thiab kev tsis sib haum xeeb ntawm cov chav kawm qis, xaus nrog ntau yam. ntawm kev raug mob. Nws yuav yog qhov tsis txaus ntseeg tiag tiag thaum txhua tus neeg tsis txaus siab nrhiav kev tshem tawm Bartholomew Txoj Kev Ncaj Ncees hauv nroog txhawm rau tsim kom muaj qhov zoo sib xws hauv qhov zoo nkauj tshaj plaws ntawm lub nroog, nyob ib sab ntawm lub palace. Qhov no yog qhov kev tsis lees paub tau piav qhia nyob rau hnub ntawd.

Txawm li cas los xij, xyoo 1851 tau muaj kev nthuav qhia nyob rau ntawd, uas tau npaj los ntawm qhov pib ua ib ntus. Yog li ntawd, Crystal Palace - Crystal Palace tau npaj ua ib qho kev tsim ua ib ntus. Lub tswv yim los sib sau ua ke ntawm cov qauv ntawm cov qauv tsim tau raug xa los ntawm tus kws tsim vaj tsev vaj ntxwv, tus kws ua vaj tsev thiab botanist - Joseph Paxton, uas, los ntawm qhov xwm txheej ntawm nws txoj haujlwm, tau koom nrog kev tsim kho ntawm iav tsev cog khoom pavilions.

Lub ntsiab kom zoo dua ntawm Paxton lub tsev xog paj yog lawv qhov kev txav mus los. Nws muaj hnub nyoog 47 xyoo thaum, xyoo 1850, kev sib tw rau kev tsim vaj tsev rau lub Ntiaj Teb Kev Ncaj Ncees tau tshaj tawm. Tom qab Paxton lub xub pwg nyom los ntawm lub sijhawm ntawd yog Lub Tsev Kho Mob Zoo Tshaj Plaws, ua rau xyoo 1837 (tshem tawm vim tus nqi siab ntawm kev saib xyuas hauv 1923), uas lub sijhawm ntawd yog lub tsev iav loj tshaj plaws hauv ntiaj teb. Lub tsev cog khoom loj iav tau ua kom sov nrog 8 boilers thiab 11 mais ntawm cov kav dej. Yauxej tus tsim lub tsev nthuav qhia tau pom zoo rau pej xeem thiab lees txais los ntawm pawg thawj coj. Kev tsim kho ntawm cam khwb cia hlau thiab daim iav iav (tau txais los ntawm ib txoj kev tsis ntev los no invented), raws li nws yog, embodied qhov tseeb achievements ntawm British science thiab kev lag luam, yog tus pheej yig thiab yuav disassembled tom qab kawg ntawm lub exhibition. Tus kws kes duab vajtse ua haujlwm tau txais txiaj ntsig zoo - nws tau raug knighted.

Ua tib zoo mloog lo lus "ntev". Tib neeg tsis tau paub txog cov txheej txheem ib ntus nyob rau nruab nrab ntawm lub xyoo pua 19th: o) Temporality tsis yog ib txwm yuam los ntawm qhov tseem ceeb heev. Feem ntau (tshwj xeeb tshaj yog qhov teeb meem ntsig txog cov neeg muaj hwj chim thiab cov neeg nplua nuj tsuas yog) lub cev nqaij daim tawv yog qhov tseem ceeb ntawm cov xwm txheej lom zem. Yog li ntawd nws yog qhov txawv txav los nyeem qhov kev xav

Tsis yog vim nws yuav "yob", tab sis tsuas yog vim lawv tau npaj ua ib ntus. Los ntawm txoj kev, Crystal Palace, tsim nrog kev siv cov modules, sawv hauv Hyde Park rau ntau tshaj 6 lub hlis raws li daim ntawv cog lus, tom qab uas nws tau dismantled, muag rau seem, yuav thiab ntsia rau ntawm qhov chaw tshiab, qhov twg ib tug railway. kab tau coj mus rau nws, thiab qhov twg nws ua haujlwm txog thaum hluav taws xyoo 1936 …

Rau rau lub hlis ntawm nws thawj qhov kev ua haujlwm, Crystal Palace tau ua tiav tag nrho nws cov kev tsim kho thiab tau txais txiaj ntsig ntawm 160,000 phaus ntawm tus nqi tsim kho ntawm 150,000. Cia kuv ceeb toom rau koj tias qhov no yog thawj qhov kev nthuav qhia thoob ntiaj teb thiab kev ncaj ncees ntawm kab lis kev cai thiab kev lag luam. Cov neeg koom tau coj cov qib siab tshaj plaws ntawm no. Thiab tus kws tshaj lij, Askiv, tau mus ua qauv qhia rau tag nrho lub ntiaj teb lub hwj chim ntawm nws lub teb chaws Ottoman thiab txhawb nws cov khoom txawv teb chaws. Tab sis historians tsis them rau qhov no:

Tau pom cov duab xyoo 1915 nrog lub teeb "hloov txawv txawv" rau saum ntuj thaum, raws li nws, lawv tsuas hnov txog hluav taws xob, Mig tsis txawj ntse. Nws yeej tsis paub lawv yog 1915 duab:o)

Ntawm chav kawm, qhov tseeb tias kev yees duab tswj tau qhia rau peb lub zeem muag ntawm kev nthuav qhia uas tau tshwm sim ua ntej peb yug los yog ib qho koob hmoov. Tab sis yeej tsis muaj duab. Lawv tau hloov los ntawm kev kos duab thiab kos duab. Cov kev xav ntawm xyoo 1851 tau raug ntes los ntawm Dickinson thiab muaj nyob rau hauv ib phau ntawv uas tau luam tawm xyoo 1852 (yuav luag tam sim ntawd tom qab ua tiav ntawm qhov kev nthuav qhia).

Hauv Dixons cov duab kos duab, kuj tseem muaj cov ntsiab lus xws li cov teeb, uas ua rau pom lub tsev thiab nthuav tawm lawv tus kheej. Tsis tas li ntawd, cov duab qhia tau hais tias qhov chaw nyob li cas feem ntau illuminated thaum lub sijhawm ntawd.

tswm ciab!

Teeb thiab teeb teeb (nrog txhua yam kev coj noj coj ua)

Kuv xav tias cov duab lawv tus kheej yuav nthuav rau koj xav txog. Nov yog qee qhov.

Cov neeg txaus siab tuaj yeem saib hauv phau ntawv lossis tig mus rau lub tshuab tshawb nrhiav: o)

Cia peb mus rau qhov txheej txheem.

Ntxiv nrog rau cov duab kos, phau ntawv muaj cov lus piav qhia luv luv ntawm qhov nthuav tawm ntawm cov neeg koom nrog tseem ceeb. Nov yog qhov uas tau txais kev mloog ntawm tus sau phau ntawv hauv German nthuav tawm:

"Txawm li cas los xij, qhov nthuav tshaj plaws ntawm tag nrho cov ntaub ntawv tau nthuav tawm yog cov xov tooj hluav taws xob electromagnetic nrog kev ntxiv thiab kev txhim kho rau cov txheej txheem ntawm American professor Morse. nyob rau hauv lub ntsis ntawm ib tug cwj mem, uas yog txuas nrog ib tug electromagnet, maj mam tawm ib tug ntev strip ntawm daim ntawv los ntawm daim ntawv rau cov menyuam uas nws raug mob, yog li kos ib txoj kab ncaj nraim rau ntawm daim ntawv thaum nws unrolled mus txog rau thaum hluav taws xob tam sim no los ntawm cov hlau activated. cov hlau nplaum thiab hloov txoj hauj lwm ntawm tus cwj mem. thiab nws yuav tsum pom tseeb npaum li cas yooj yim txoj cai no, thaum ua tiav, tuaj yeem siv rau hauv kev coj ua kom muaj kev txawj ntse."

Nyob zoo cov neeg nyeem. Kuv thov kom delve rau hauv cov theem ntawm kev loj hlob ntawm kev siv tshuab thiab technology txij li thawj lub ntiaj teb exhibition. Ua li no, kuv muab cov lus piav qhia ntawm cov tshuab (mechanization) nthuav tawm, ua nrog kev pab ntawm lub tshuab txhais lus (uas yog, hluav taws xob):

ENGINEERING

Cov khoom loj loj ntawm cov tshuab ntawm txhua yam ntawm Great Exhibition tau ua rau Askiv nyob rau hauv txoj haujlwm zoo siab ntawm cov neeg sib tw, vim tias tag nrho nws cov kev koom tes tau ua tau zoo nyob rau hauv qhov tshiab, muaj txiaj ntsig thiab ua tau zoo hauv kev ua haujlwm. Muaj xya pua horsepower plaub-lub tog raj kheej marine steam engines, hais tias yog qhov loj tshaj plaws, tab sis ua rau cov kiv cua-tsav nkoj: muaj cov tshiab thiab loj loj yim-log locomotives, tom qab Crampton tus tsim, uas tuaj yeem khiav ntawm qhov yooj yim ntawm kev ceev. xya caum mais ntawm ib teev, vim qhov peculiarity ntawm txoj hauj lwm ntawm lub log tsav, lub qag ntawm uas nyob tom qab lub firebox, ib tug mechanism uas muab ib tug ntau dua piv rau stability ntawm lub zog, tshwj xeeb tshaj yog nyob rau hauv high speeds.

Ua ntej tau tsim lub Great Hydraulic Xovxwm, uas txawv tsis tsuas yog nyob rau hauv nws loj, tab sis kuj nyob rau hauv ntau yam khoom siv los tuav lub chains nrog kev pab los ntawm cov kav dej ntawm lub British Choj tau tsa nyob rau hauv lub Menai Strait, lub triumphal arch ntawm niaj hnub engineering., nyob rau hauv uas txoj kab ntawm ib tug battleship yuav kis tau nrog cua nrog tag nrho cov sails; thaum nyob rau txhua sab, nyob ib ncig ntawm no enormous apparatus, phav phav lub tshuab me me, uas tag nrho deserved lub epithet zoo nkauj, ua hauj lwm nyuaj thiab inventively koom nyob rau hauv lub tsim ntawm txhua yam ntawm cov khoom muaj txiaj ntsig, los ntawm riam phom mus rau lub hnab ntawv. Nyob rau hauv no department, uas tej zaum yuav zoo hu ua ib tug loj fleet ntawm lub tsheb, tus neeg soj ntsuam kev xav tau yooj yim pom tus cwj pwm txawv ntawm lub teb chaws Askiv nyob rau hauv relation mus poetic economics; Cov neeg Askiv ntiav lawv cov peev, tab sis pheej nrhiav kev siv tshuab ua kom nws ua haujlwm.

Raws li kev faib tawm ntawm Dr. Lyon Playfire tau txais los ntawm Royal Commissioners, Mechanical Engineering tau tsim ib qho ntawm plaub qhov kev faib loj rau hauv cov qauv ntawm txhua yam khoom uas tuaj yeem nthuav tawm tau muab faib.

Qhov kev faib tawm no tau muab faib ua rau chav kawm: Cov tshuab siv ncaj qha; 2. Kev tsim cov tshuab thiab cov cuab yeej; 3. Mechanical, engineering thiab architectural tsim khoom siv; 4. Naval architecture thiab tub rog engineering; 5. Agricultural thiab horticultural tshuab thiab siv; 6. Philosophical, suab paj nruag, saib, acoustic thiab ntau yam twj paj nruag.

Qhov kev faib tawm no tau muab lo lus "mechanism" nkag siab ntau dua li yav dhau los; tab sis txawm hais tias Dr. Playfair yog txoj cai lossis tsis yog hauv cov lus xaus rau hauv ib tshooj cov kab lus uas mus txog rau lub sijhawm ntawd ib txwm tau muab cais cais, cov txheej txheem saum toj no yeej yooj yim heev rau cov khoom tam sim nws muaj nyob rau hauv lub siab, thiab yog li tsim nyog qhuas tsis kawg rau qhov ntawd. tau ua siab loj txaus los ua lub sij hawm "machine" yog li tag nrho-encompassing xws li txhua lub cav lossis cov cuab yeej uas xa mus rau hauv cov ntawv hloov pauv, txawm tias tsiaj lossis khoom siv, siv rau nws.

Tus kws ua yeeb yam tau ua siab tawv zoo li Dr. Playfire, thiab tau sib sau ua ke ntau yam khoom siv sib txawv hauv lub phaj nrog uas peb muaj lub sijhawm nyuaj tshaj plaws los txiav txim seb qhov twg los saib. Ua ntej ntawm tag nrho cov yog Nasmyth lub zog rauj, uas yog nto moo heev rau hloov lub qub tilted rauj yuav tsum tau ntau dua yuav tsum tau hais nyob rau hauv nws kev qhuas, raws li nws yog tam sim no tau ua rau hnyav tshaj forgings. Lub tsuas xav paub qhov tseeb nyob rau hauv no hais txog, uas tej zaum yuav tsis yog feem ntau paub, yog hais tias thaum ntxov raws li 1784 James Watt hais nyob rau hauv nws specification txuas nrog nws patent daim ntawv thov uas lub tswv yim ntawm kev siv chav zog nyob rau hauv kev twb kev txuas nrog ib tug rauj tshwm sim; tab sis nws yeej tsis tau tsim ib txoj hauv kev zoo ntawm kev siv rauj - txuas rau lub piston pas nrig nws tus kheej; thiab nws ua tsaug rau cov neeg txawj ntse ntawm peb lub sijhawm uas peb tab tom ua cov kauj ruam tseem ceeb no.

Ntawm ntau lub tshuab hluav taws xob thiab cov twj tso kua mis, lub tog raj kheej hydraulic tsim los ntawm Mr. Easton thiab Amos tuaj yeem raug suav hais tias yog ib qho yooj yim heev thiab siv tau zoo los ntawm ntau lub teb chaws tam sim no muab cov dej; qhov tsuas yog qhov yuav tsum tau muaj yog qhov me me hauv ib puag ncig. Nyob ze yog tus qauv Maplin lighthouse, raws li Mitchell ntsia hlau pawg, txoj kev npaj uas zoo siab rau cov av xuab zeb uas cov paddles nyuaj tsav. Thaum kawg, peb xav ntxiv ib lo lus qhuas txog Ms. Ransom thiab May txoj kev tsheb ciav hlau faucet, uas tau tsim muaj lub ntsej muag nqa tau zoo heev kom nws txav tawm ntawm txoj kev tsheb ciav hlau thaum tsis xav tau los ua kom tiav qhov kev sib tw. Tab sis tsis muaj cov lus piav qhia ntawm Lub Chaw Ua Si Machine tuaj yeem muab lub tswv yim tsim nyog ntawm qhov tseem ceeb ntawm nws cov ntsiab lus rau cov neeg uas tsis tuaj xyuas nws: ib lub lim tiam kev tshuaj xyuas tsis txaus kom tso tag nrho nws cov khoom muaj nqis; Yuav ua li cas peb cia siab tias yuav ua tau ntau tshaj li tsuas yog pab lub cim xeeb kom nco ntsoov ib tug tiag tiag scene uas peb ib zaug pom, yuav tsis nco qab lawm?” (tej nplooj ntawv)

Yog li ntawd, 1) Thawj lub ntiaj teb kev nthuav qhia tsis tau qhia super-duper thev naus laus zis piv rau peb lub sijhawm, tab sis rau nruab nrab ntawm lub xyoo pua 19th nws tau siab heev. Qhov chaw me me dhau los tau muab rau kev lag luam thiab kev ua haujlwm thev naus laus zis.

2) Muaj teeb pom kev zoo ntawm qhov kev nthuav qhia. Tsis pom lub qhov cub hluav taws xob, thiab tsis muaj hluav taws xob.… Tab sis! Rov qab rau xyoo pua 18th, roj teeb tau tsim (koj tuaj yeem paub txog qhov no hauv cov tsev qiv ntawv thev naus laus zis hauv Is Taws Nem).

3) Hluav taws xob twb tau kawm lawm, thawj cov cuab yeej tau tsim nyob rau hauv uas nws tau siv.

Hluav taws xob tawm ntawm huab cua nyias, los yog cov keeb kwm tsis khiav tom qab txhua daim txhuam cev

Muaj kev sib tw ua yeeb yam ntawm cov nroog loj hauv Tebchaws Meskas los tuav lub rooj sib tham no.

Chicago tau raug xaiv ib nrab vim nws yog ib qho chaw tsheb ciav hlau thiab ib nrab vim nws muab $ 10 lab lav.

Qhov loj ntawm "White City" (lub thiaj li hu ua complex ntawm exhibition halls ua los ntawm limestone), illuminated los ntawm hluav taws xob hmo ntuj, ib ntus coj mus rau lub rooj txhawb siab ntawm kev txaus siab nyob rau hauv classical architecture.

Tom qab lub facades nyob ntsiag to thiab classical porticos ntawm qhov zoo "White City", tus qhua poob nthav pom qhov tshiab thiab kev zoo siab. Ferris log (tsim los ntawm J. G. Ferris, tus kws ua choj Pittsburgh) thiab dazzling ib qho txuj ci tseem ceeb tshiab - hluav taws xob - yog thawj zaug hauv Asmeskas.

Hluav taws xob tau "tshem tawm" thiab ua haujlwm ntawm Paris Exhibition ntawm 1889, tab sis nyob rau hauv 1893 nws tseem tsis tau paub txog cov neeg Asmeskas feem ntau. Cov khoom pov thawj tau qhib nrog kev ua siab zoo, ua yeeb yam thaum US Thawj Tswj Hwm Grover Cleveland nias lub pob ntawm lub platform pem hauv ntej ntawm Lub Tsev Tswj Xyuas thiab pib lub cav loj Allis tig rau hluav taws xob rau qhov raug.

Lub cav, dynamo thiab alternator, thawj zaug pom los ntawm George Westinghouse, tom qab ntawd los ua cov cuab yeej tseem ceeb ntawm kev lag luam hluav taws xob. Los ntawm lub exhibition prospectus:

ELECTRICITY. Cov khoom pov thawj muab kaum xya txhiab horsepower rau hluav taws xob teeb pom kev zoo. Qhov no yog kaum npaug tshaj li thaum lub sij hawm Paris Exhibition ntawm 1889, thiab 9,000 incandescent teeb thiab 5,000 arc teeb yuav muab. Lub tshuab fais fab ib leeg raug nqi $1,000,000…

Ib lub pas dej loj loj uas muaj nqis txog $ 50,000, 150 feet ntawm txoj kab uas hla, sawv sab nraum lub tsev tswj hwm. Nws cov dej tau teeb nrog hluav taws xob …

Hall ntawm Hluav Taws Xob

Ntu hluav taws xob yog kab tias qhov kev nthuav qhia tshiab tshaj plaws thiab ci ntsa iab tshaj plaws hauv kev nthuav tawm tag nrho. Lub tsev yog 345 ko taw dav thiab 700 ko taw ntev, nrog rau sab qaum teb-sab qab teb axis loj …

Cov txheej txheem dav dav ntawm txoj kev npaj yog ua raws li lub nkoj ntev ntev 115 ko taw dav thiab 114 ko taw siab, hla hauv nruab nrab los ntawm kev sib kis ntawm tib qhov dav thiab qhov siab. Lub nave thiab transept muaj ib lub ru tsev pitched nrog ntau skylights thiab pob tshab qhov rais. Tus so ntawm lub tsev yog them nrog lub ru tsev tiaj tus, qhov nruab nrab ntawm 62 ko taw siab, nrog dormer windows. Lub cheeb tsam thib ob muaj cov chav ua yeeb yam txuas thoob plaws lub nave los ntawm ob lub choj, nrog plaub lub staircases loj. Cov chav tsev thib ob yog 118,546 square feet, lossis 2.7 acres. “Tus nqi yog kwv yees li 375,000 las….

Muaj ib lub pavilion ntawm txhua ntawm plaub fab ntawm lub tsev, uas yog dominated los ntawm lub teeb qhib spire los yog ntauwd 169 ko taw siab. Nruab nrab ntawm cov ces kaum pavilions thiab lub hauv paus pavilions nyob rau sab hnub tuaj thiab sab hnub poob yog ib tug subordinate pavilion nrog ib tug tsawg square dome rau ib tug qhib teeb. Nyob rau hauv ib lub niche nyob rau hauv nruab nrab ntawm lub sab qab teb pavilion, nyob rau hauv lub siab plinth, sawv ib tug colossal pej thuam ntawm Benjamin Franklin, txoj cai them tribute rau qhov tseem ceeb discoveries nws ua nyob rau hauv lub teb ntawm hluav taws xob ….

Ntawm no koj tuaj yeem pom cov khoom siv uas qhia txog qhov tshwm sim thiab cov cai ntawm hluav taws xob thiab hlau nplaum, nrog rau cov khoom siv rau kev ntsuas hluav taws xob; roj teeb hluav taws xob; cov khoom siv rau kev tsim hluav taws xob, kev xa hluav taws xob; hluav taws xob motors; hluav taws xob teeb pom kev zoo thiab cua sov; khoom siv rau electrometallurgy thiab chemistry; telegraph thiab hluav taws xob signaling mechanisms; xov tooj thiab khoom siv hauv tsev raug nthuav tawm; phonographs; hluav taws xob hauv kev phais thiab kho hniav; keeb kwm ntawm hluav taws xob invention; zoo tag nrho cov cuab yeej thiab inventions muaj feem xyuam rau niaj hnub kev vam meej thiab kev loj hlob nyob rau hauv lub teb ntawm hluav taws xob engineering. Los ntawm no

Saib ntau npaum li cas cov ntaub ntawv zais cia sab saum toj tseem tshuav ntawm qhov kev nthuav qhia heev! (qhov no tsuas yog nyob rau hauv ib qho chaw, kuv khawb me ntsis)

Muaj cov duab, cov lus ceeb toom, thiab txhua yam nthuav tawm lwm yam! Tab sis cov neeg tsis nyeem ntawv no tsuas yog rov hais dua qhov tsis muaj tseeb tom qab lwm tus neeg keeb kwm, lawv hais tias, tsis muaj dab tsi, Vatican zais

Cov lus nug tsis yooj yim: cov lus teb tau muab rau lub sijhawm ntev thiab ntau dua ib qho chaw. Piv txwv li, ntawm tib lub rooj sib tham, ib daim ntawv tshaj tawm tau nyeem txog hluav taws xob:
