Prof. Moran Bercovici thiab Dr. Valeri Frumkin tau tsim cov thev naus laus zis pheej yig rau kev tsim cov tsom iav qhov muag, thiab nws muaj peev xwm tsim cov tsom iav rau ntau lub teb chaws uas tsim cov tsom iav tsis muaj.Tam sim no, NASA hais tias nws tuaj yeem siv los ua lub tsom iav qhov chaw
Kev tshawb fawb feem ntau nce qib me me.Ib daim ntawv me me ntxiv rau txhua qhov kev sim tshiab.Nws tsis tshua muaj lub tswv yim yooj yim uas tshwm sim hauv lub hlwb ntawm tus kws tshawb fawb ua rau muaj kev cuam tshuam loj yam tsis tau siv cov cuab yeej technology.Tab sis qhov no yog qhov tshwm sim rau ob tug Israeli engineers uas tau tsim ib txoj hauv kev tshiab ntawm kev tsim cov lo ntsiab muag kho qhov muag.
Lub kaw lus yooj yim, pheej yig thiab raug, thiab tuaj yeem muaj kev cuam tshuam loj txog li ib feem peb ntawm cov neeg hauv ntiaj teb.Nws kuj tseem yuav hloov lub ntsej muag ntawm kev tshawb nrhiav chaw.Txhawm rau tsim nws, cov kws tshawb fawb tsuas yog xav tau lub rooj tsav xwm dawb, lub cim, lub lwv thiab koob hmoov me ntsis.
xibfwb Moran Bercovici thiab Dr. Valeri Frumkin los ntawm Mechanical Engineering Department ntawm Technion-Israel Institute of Technology hauv Haifa tshwj xeeb hauv cov tshuab ua kua dej, tsis yog optics.Tab sis ib xyoos thiab ib nrab dhau los, ntawm World Laureate Forum nyob rau hauv Shanghai, Berkovic tau tshwm sim los zaum nrog David Ziberman, Israeli economist.
Zilberman yog tus yeej Wolf Prize, thiab tam sim no ntawm University of California, Berkeley, nws tau tham txog nws txoj kev tshawb fawb hauv cov tebchaws tsim.Bercovici piav txog nws qhov kev sim ua kua dej.Ces Ziberman nug ib lo lus nug yooj yim: "Koj puas tuaj yeem siv qhov no los ua iav?"
Berkovic tau hais tias "Thaum koj xav txog kev tsim lub tebchaws, koj feem ntau xav txog malaria, tsov rog, kev tshaib kev nqhis," Berkovic tau hais."Tab sis Ziberman tau hais qee yam uas kuv tsis paub txhua-2.5 billion tus neeg hauv ntiaj teb xav tau tsom iav tab sis tsis tuaj yeem tau txais lawv.Qhov no yog tus lej amazing. "
Bercovici rov qab los tsev thiab pom tias tsab ntawv ceeb toom los ntawm World Economic Forum tau lees paub tus lej no.Txawm hais tias nws tsuas yog nqi ob peb duas las los ua ib nkawm tsom iav yooj yim, cov iav pheej yig tsis yog tsim los yog muag hauv ntau qhov chaw hauv ntiaj teb.
Qhov cuam tshuam loj heev, xws li cov menyuam yaus uas tsis tuaj yeem pom daim ntawv teev npe dub hauv tsev kawm ntawv mus rau cov neeg laus uas qhov muag tsis pom kev zoo heev uas lawv poob haujlwm.Ntxiv nrog rau kev ua phem rau tib neeg lub neej zoo, tus nqi ntawm kev lag luam thoob ntiaj teb tau kwv yees siab txog US $ 3 trillion toj xyoo.
Tom qab kev sib tham, Berkovic pw tsis tsaug zog hmo ntuj.Thaum nws tuaj txog ntawm Technion, nws tau tham txog qhov teeb meem no nrog Frumkin, uas yog tus kws tshawb fawb tom qab kawm tiav hauv nws chav kuaj thaum lub sijhawm.
Nws hais tias, "Peb tau kos duab rau ntawm daim ntawv dawb thiab saib nws," nws hais."Peb paub instinctively tias peb tsis tuaj yeem tsim cov duab no nrog peb cov cuab yeej tswj dej, thiab peb xav paub vim li cas."
Cov duab kheej kheej yog lub hauv paus ntawm optics vim tias lub lens yog ua los ntawm lawv.Nyob rau hauv txoj kev xav, Bercovici thiab Frumkin paub tias lawv tuaj yeem ua ib puag ncig lub dome los ntawm polymer (cov kua uas muaj zog) los ua lub lens.Tab sis cov kua tsuas tuaj yeem nyob twj ywm kheej kheej hauv cov ntim me me.Thaum lawv loj dua, lub ntiajteb txawj nqus yuav squash lawv mus rau hauv av.
Bercovici piav qhia tias "Yog li peb yuav tsum ua yog tshem tawm lub ntiajteb txawj nqus,"Thiab qhov no yog qhov nws thiab Frumkin tau ua.Tom qab kawm lawv cov ntawv dawb, Frumkin tuaj nrog lub tswv yim yooj yim heev, tab sis nws tsis paub meej tias yog vim li cas tsis muaj leej twg xav txog nws ua ntej - yog tias lub lens muab tso rau hauv cov kua chamber, cov nyhuv ntawm lub ntiajteb txawj nqus tuaj yeem raug tshem tawm.Txhua yam koj yuav tsum tau ua yog kom paub tseeb tias cov kua nyob rau hauv lub chamber (hu ua buoyant kua) muaj tib qhov ntom li cov polymer los ntawm lub lens yog tsim, thiab tom qab ntawd cov polymer yuav ntab.
Lwm qhov tseem ceeb yog siv ob qho dej tsis sib xws, uas txhais tau hais tias lawv yuav tsis sib xyaw nrog ib leeg, xws li roj thiab dej.Bercovici tau hais tias "Feem ntau cov polymers zoo li cov roj, yog li peb cov lus 'buoyant kua yog dej," Bercovici tau hais.
Tab sis vim dej muaj qhov ntom ntom dua li cov polymers, nws qhov ntom yuav tsum tau nce me ntsis kom cov polymer yuav ntab.Txog rau qhov kawg no, cov kws tshawb fawb kuj tau siv cov khoom sib txawv tsawg - ntsev, qab zib lossis glycerin.Bercovici tau hais tias qhov kawg ntawm cov txheej txheem yog lub thav duab nruj rau hauv cov polymer yog txhaj kom nws daim ntawv tuaj yeem tswj tau.
Thaum cov polymer mus txog nws daim ntawv kawg, nws kho tau siv hluav taws xob ultraviolet thiab dhau los ua lub lens khoom.Txhawm rau ua cov thav duab, cov kws tshawb fawb siv cov kav dej phwj yooj yim, txiav rau hauv lub nplhaib, lossis ib lub tais petri txiav los ntawm hauv qab.Bercovici tau hais tias "Txhua tus menyuam tuaj yeem ua rau lawv nyob hauv tsev, thiab kuv cov ntxhais thiab kuv tau ua qee yam hauv tsev," Bercovici tau hais."Ntau xyoo dhau los, peb tau ua ntau yam hauv chav kuaj, qee qhov nyuaj heev, tab sis tsis muaj qhov tsis ntseeg tias qhov no yog qhov yooj yim thiab yooj yim tshaj plaws uas peb tau ua.Tej zaum qhov tseem ceeb tshaj plaws. "
Frumkin tsim nws thawj txhaj tshuaj nyob rau tib hnub nws xav txog kev daws."Nws xa kuv daim duab rau WhatsApp," Berkovic nco qab."Hauv kev rov qab los, qhov no yog lub lens me me thiab tsis zoo, tab sis peb zoo siab heev."Frumkin txuas ntxiv mus kawm qhov kev tsim kho tshiab no.“Qhov sib npaug qhia tau hais tias ib zaug koj tshem lub ntiajteb txawj nqus, nws tsis muaj teeb meem seb tus ncej yog ib nti lossis ib mais;nyob ntawm seb cov khoom siv ntau npaum li cas, koj yuav tau txais cov duab zoo ib yam. "
Ob tus kws tshawb fawb txuas ntxiv mus sim nrog cov khoom siv zais cia thib ob, lub thoob khib nyiab, thiab siv nws los tsim lub lens nrog txoj kab uas hla ntawm 20 cm uas tsim nyog rau lub koob yees duab.Tus nqi ntawm lub lens nce exponentially nrog txoj kab uas hla, tab sis nrog txoj kev tshiab no, tsis hais qhov loj me, txhua yam koj xav tau yog pheej yig polymer, dej, ntsev (los yog glycerin), thiab lub nplhaib pwm.
Daim ntawv teev cov khoom siv qhia tau tias muaj kev hloov pauv loj hauv cov txheej txheem tsim lub lens uas tseem yuav luag tsis hloov rau 300 xyoo.Nyob rau hauv thawj theem ntawm cov txheej txheem ib txwm, ib khob los yog yas phaj yog mechanically hauv av.Piv txwv li, thaum tsim cov tsom iav tsom iav, kwv yees li 80% ntawm cov khoom siv pov tseg.Siv cov txheej txheem tsim los ntawm Bercovici thiab Frumkin, es tsis txhob sib tsoo cov ntaub ntawv, cov kua yog txhaj rau hauv lub thav duab, yog li ntawd lub lens tuaj yeem tsim nyob rau hauv cov txheej txheem tsis muaj pov tseg.Txoj kev no kuj tsis tas yuav polishing, vim tias qhov nro ntawm cov kua dej tuaj yeem ua kom lub ntsej muag du heev.
Haaretz tau mus xyuas Technion lub chaw kuaj mob, qhov chaw kws kho mob tus menyuam kawm ntawv Mor Elgarisi tau qhia txog cov txheej txheem.Nws txhaj tshuaj polymer rau hauv ib lub nplhaib hauv ib chav ua kua me me, irradiated nrog UV teeb, thiab muab kuv ob lub hnab looj tes phais ob feeb tom qab.Kuv ua tib zoo dipped kuv txhais tes rau hauv dej thiab rub tawm lub lens."Qhov ntawd yog nws, kev ua tiav lawm," Berkovic qw.
Cov lo ntsiab muag yog kiag li du rau qhov kov.Qhov no tsis yog ib qho kev xav xwb: Bercovici hais tias txawm tias tsis muaj polishing, qhov roughness ntawm lub lens ua los ntawm polymer txoj kev yog tsawg dua ib nanometer (ib billionth ntawm ib meter).Nws tau hais tias "Lub zog ntawm ntuj tsim qhov zoo tshaj plaws ntawm lawv tus kheej, thiab lawv muaj kev ywj pheej," nws hais.Hauv qhov sib piv, cov iav kho qhov muag yog polished rau 100 nanometers, thaum lub iav ntawm NASA tus flagship James Webb Space Telescope yog polished rau 20 nanometers.
Tab sis tsis yog txhua leej txhua tus ntseeg tias txoj kev zoo nkauj no yuav yog tus cawm seej ntawm ntau lab tus tib neeg thoob ntiaj teb.Xib fwb Ady Arie los ntawm Tel Aviv University Lub Tsev Kawm Ntawv ntawm Hluav Taws Xob Engineering tau taw qhia tias Bercovici thiab Frumkin txoj kev xav tau lub voj voog pwm rau hauv cov kua polymer yog txhaj, cov polymer nws tus kheej thiab lub teeb ultraviolet.
"Cov no tsis muaj nyob hauv cov zos Indian," nws hais.Lwm qhov teeb meem tau tsa los ntawm SPO Precision Optics tus tsim thiab tus lwm thawj ntawm R&D Niv Adut thiab lub tuam txhab tus thawj kws tshawb fawb Dr. Doron Sturlesi (ob leeg paub txog Bercovici txoj haujlwm) yog tias kev hloov cov txheej txheem sib tsoo nrog cov yas castings yuav ua rau nws nyuaj rau hloov lub lens rau lub xav tau.Nws cov neeg.
Berkovic tsis ntshai."Kev thuam yog ib feem tseem ceeb ntawm kev tshawb fawb, thiab peb txoj kev loj hlob sai nyob rau xyoo dhau los no feem ntau yog vim cov kws tshaj lij thawb peb mus rau kaum," nws hais.Hais txog qhov muaj peev xwm ntawm kev tsim khoom hauv thaj chaw deb, nws hais ntxiv tias: "Cov txheej txheem tsim nyog los tsim cov iav siv cov txheej txheem ib txwm muaj yog qhov loj;koj xav tau cov chaw tsim khoom, tshuab, thiab cov kws tshaj lij, thiab peb tsuas yog xav tau qhov tsawg kawg nkaus infrastructure. "
Bercovici tau qhia peb ob lub teeb hluav taws xob ultraviolet hauv nws chav kuaj: "Qhov no yog los ntawm Amazon thiab raug nqi $ 4, thiab lwm qhov yog los ntawm AliExpress thiab tus nqi $ 1.70.Yog tias koj tsis muaj lawv, koj tuaj yeem siv Sunshine ib txwm, "nws piav qhia.Yuav ua li cas yog polymers?"Ib lub raj mis 250-ml muag rau $ 16 ntawm Amazon.Lub lens nruab nrab xav tau 5 mus rau 10 ml, yog li tus nqi ntawm cov polymer tsis yog qhov tseem ceeb. "
Nws hais ntxiv tias nws txoj kev tsis tas yuav tsum siv cov pwm tshwj xeeb rau txhua tus lej lo ntsiab muag, raws li cov neeg thuam hais.Ib qho pwm yooj yim yog tsim rau txhua tus lej lo ntsiab muag, nws piav qhia tias: "Qhov txawv yog qhov ntau ntawm cov tshuaj polymer txhaj, thiab ua ib lub tog raj kheej rau cov iav, txhua yam uas yuav tsum tau yog ncab cov pwm me ntsis."
Bercovici tau hais tias tsuas yog ib feem kim ntawm cov txheej txheem yog automation ntawm kev txhaj tshuaj polymer, uas yuav tsum tau ua tiav raws li tus naj npawb ntawm lo ntsiab muag xav tau.
"Peb txoj kev npau suav yog kom muaj kev cuam tshuam hauv lub tebchaws nrog cov peev txheej tsawg tshaj plaws," Bercovici tau hais.Txawm hais tias cov iav pheej yig tuaj yeem coj mus rau cov zos txom nyem-txawm tias qhov no tsis tau ua tiav-nws txoj kev npaj yuav loj dua.“Ib yam li cov lus pov thawj nto moo, kuv tsis xav muab ntses rau lawv, kuv xav qhia lawv paub ntses.Ua li no, tib neeg yuav muaj peev xwm ua lawv tus kheej tsom iav, "nws hais.“Nws puas yuav ua tiav?Tsuas yog lub sijhawm yuav muab cov lus teb. "
Bercovici thiab Frumkin tau piav qhia txog cov txheej txheem no hauv ib tsab xov xwm txog rau lub hlis dhau los hauv thawj tsab ntawm Flow, ib phau ntawv xov xwm ntawm cov dej siv tshuab luam tawm los ntawm University of Cambridge.Tab sis pab neeg no tsis xav kom nyob twj ywm ntawm qhov yooj yim optical lo ntsiab muag.Lwm daim ntawv luam tawm nyob rau hauv Optica magazine ob peb lub lis piam dhau los tau piav qhia txog ib txoj hauv kev tshiab rau kev tsim cov khoom siv kho qhov muag hauv thaj tsam ntawm daim ntawv dawb optics.Cov khoom siv kho qhov muag no tsis yog convex lossis concave, tab sis yog molded rau hauv qhov chaw saum npoo, thiab lub teeb yog irradiated rau saum npoo ntawm ntau qhov chaw kom ua tiav cov txiaj ntsig xav tau.Cov khoom no tuaj yeem pom muaj nyob rau hauv cov iav multifocal, pilot kaus mom hlau, cov tshuab ua haujlwm siab heev, cov tshuab virtual thiab augmented kev muaj tiag, thiab lwm qhov chaw.
Kev tsim cov khoom siv dawb-dawb uas siv cov txheej txheem ruaj khov yog qhov nyuaj thiab kim vim tias nws nyuaj rau zom thiab txhuam lawv thaj chaw.Yog li ntawd, cov khoom siv tam sim no muaj kev siv tsawg.Bercovici tau piav qhia tias "Tseem muaj kev tshaj tawm kev kawm txog kev siv tau ntawm cov chaw zoo li no, tab sis qhov no tseem tsis tau muaj kev cuam tshuam hauv kev siv tau," Bercovici piav qhia.Nyob rau hauv daim ntawv tshiab no, pab neeg soj ntsuam coj los ntawm Elgarisi tau qhia yuav ua li cas los tswj lub nto daim ntawv tsim thaum polymer kua yog txhaj los ntawm kev tswj cov daim ntawv ntawm tus ncej.Lub thav duab tuaj yeem tsim tau siv lub tshuab luam ntawv 3D.Bercovici tau hais tias "Peb tsis ua tej yam nrog lub thoob mop lawm, tab sis nws tseem yooj yim heev,"
Omer Luria, tus kws tshaj lij kev tshawb fawb ntawm lub chaw soj nstuam, tau taw qhia tias cov thev naus laus zis tshiab no tuaj yeem tsim cov lo ntsiab muag tshwj xeeb nrog cov av tshwj xeeb."Peb cia siab tias nws tuaj yeem txo tus nqi thiab lub sijhawm tsim khoom ntawm cov khoom siv kho qhov muag nyuaj," nws hais.
Xibfwb Arie yog ib tug ntawm Optica cov neeg kho, tab sis tsis tau koom nrog kev tshuaj xyuas ntawm tsab xov xwm."Qhov no yog ib txoj haujlwm zoo heev," Ali hais txog kev tshawb fawb."Yuav kom tsim tau qhov chaw aspheric optical, txoj hauv kev tam sim no siv cov pwm lossis 3D luam ntawv, tab sis ob txoj hauv kev nyuaj los tsim cov npoo txaus thiab loj hauv lub sijhawm tsim nyog."Arie ntseeg tias txoj kev tshiab yuav pab tsim kev ywj pheej Prototype ntawm cov khoom siv raug cai."Rau kev tsim khoom ntawm ntau qhov chaw, nws yog qhov zoo tshaj plaws los npaj cov pwm, tab sis txhawm rau ntsuas cov tswv yim tshiab sai sai, qhov no yog txoj hauv kev nthuav dav thiab zoo nkauj," nws hais.
SPO yog ib qho ntawm cov neeg Ixayees cov tuam txhab ua lag luam nyob rau hauv daim ntawv dawb-dawb.Raws li Adut thiab Sturlesi, txoj kev tshiab muaj qhov zoo thiab qhov tsis zoo.Lawv hais tias kev siv cov yas txwv tsis pub muaj peev xwm vim tias lawv tsis ruaj khov ntawm qhov kub thiab txias thiab lawv lub peev xwm ua tau zoo txaus thoob plaws tag nrho cov xim yog txwv.Raws li qhov zoo, lawv tau taw qhia tias lub tshuab muaj peev xwm txo qis cov nqi tsim khoom ntawm cov lo ntsiab muag nyuaj, uas yog siv hauv txhua lub xov tooj ntawm tes.
Adut thiab Sturlesi tau hais ntxiv tias nrog cov txheej txheem tsim khoom ib txwm muaj, txoj kab uas hla ntawm cov lo ntsiab muag yas raug txwv vim tias lawv loj dua, qhov tsawg dua lawv ua.Lawv tau hais tias, raws li Bercovici txoj kev, kev tsim cov lo ntsiab muag hauv cov kua tuaj yeem tiv thaiv kev cuam tshuam, uas tuaj yeem tsim cov khoom siv kho qhov muag muaj zog heev-txawm hais tias nyob rau hauv cov lo ntsiab muag kheej kheej lossis cov lo ntsiab muag dawb.
Qhov kev npaj txhij txog tshaj plaws ntawm pab pawg Technion tau xaiv los tsim lub lens loj.Ntawm no, txhua yam pib nrog kev sib tham tsis sib haum xeeb thiab cov lus nug tsis tseeb."Nws yog txhua yam hais txog tib neeg," Berkovic hais.Thaum nws nug Berkovic, nws tab tom qhia rau Dr. Edward Baraban, tus kws tshawb fawb NASA, tias nws paub nws txoj haujlwm ntawm Stanford University, thiab nws paub nws hauv Stanford University: “Koj xav tias koj tuaj yeem ua lub lens zoo li no rau lub tsom iav qhov chaw. ?”
Berkovic hais tias, "Nws zoo li lub tswv yim vwm," tab sis nws tau sau rau hauv kuv lub siab heev.Tom qab kev sim ua tiav tiav, cov kws tshawb fawb Israeli pom tau tias txoj kev tuaj yeem siv tau hauv nws ua haujlwm tib yam hauv qhov chaw.Tom qab tag nrho, koj tuaj yeem ua tiav microgravity tej yam kev mob nyob rau ntawd yam tsis tas yuav tsum muaj cov kua dej buoyant."Kuv hu Edward thiab kuv hais rau nws, nws ua haujlwm!"
Qhov chaw telescopes muaj qhov zoo tshaj plaws hauv av-raws li telescopes vim tias lawv tsis cuam tshuam los ntawm huab cua lossis lub teeb paug.Qhov teeb meem loj tshaj plaws nrog kev txhim kho ntawm qhov chaw telescopes yog tias lawv qhov loj me yog txwv los ntawm qhov loj ntawm lub launcher.Nyob rau hauv lub ntiaj teb, telescopes tam sim no muaj ib txoj kab uas hla mus txog 40 meters.Lub Hubble Space Telescope muaj daim iav 2.4-meter-inch, thaum James Webb Telescope muaj 6.5-meter-inch iav - nws tau siv cov kws tshawb fawb 25 xyoo kom ua tiav qhov kev ua tiav no, raug nqi 9 billion US dollars, ib feem vim tias A system xav tau. tsim tawm uas tuaj yeem tso lub koob yees duab hauv txoj haujlwm folded thiab mam li qhib nws hauv qhov chaw.
Ntawm qhov tod tes, Kua twb nyob rau hauv lub xeev "folded".Piv txwv li, koj tuaj yeem sau lub transmitter nrog kua hlau, ntxiv ib qho kev txhaj tshuaj thiab lub nplhaib nthuav dav, thiab tom qab ntawd ua ib daim iav hauv qhov chaw.Berkovic tau lees tias "Qhov no yog qhov kev xav tsis thoob,"“Kuv niam nug kuv tias, 'Koj yuav npaj thaum twg?Kuv hais rau nws tias, 'Tej zaum hauv 20 xyoo.Nws hais tias nws tsis muaj sijhawm tos. "
Yog tias txoj kev npau suav no los txog tiag, nws yuav hloov lub neej yav tom ntej ntawm kev tshawb nrhiav chaw.Niaj hnub no, Berkovic tau taw qhia tias tib neeg tsis muaj peev xwm saib ncaj qha exoplanets-planets sab nraum lub hnub ci, vim tias ua li ntawd yuav tsum muaj lub koob yees duab lub ntiaj teb 10 npaug loj dua li lub tshuab hluav taws xob uas twb muaj lawm-uas yog ua tsis tau kiag li nrog cov thev naus laus zis uas twb muaj lawm.
Ntawm qhov tod tes, Bercovici tau hais ntxiv tias Falcon Heavy, tam sim no qhov chaw loj tshaj plaws launcher SpaceX, tuaj yeem nqa 20 cubic meters ntawm cov kua.Nws piav qhia tias nyob rau hauv txoj kev xav, Falcon Heavy tuaj yeem siv los tua cov kua mus rau qhov chaw orbital, qhov twg cov kua siv tau los ua ib daim iav 75-meter-inch - thaj chaw saum npoo thiab lub teeb sib sau yuav loj dua li yav tas los 100 npaug. .James Webb telescope.
Qhov no yog npau suav, thiab nws yuav siv sij hawm ntev kom paub nws.Tab sis NASA tab tom ua tiag tiag.Ua ke nrog ib pab neeg ntawm engineers thiab cov kws tshawb fawb los ntawm NASA's Ames Research Center, coj los ntawm Balaban, thev naus laus zis tau sim thawj zaug.
Thaum lub Kaum Ob Hlis Ntuj lig, ib qho kev tsim los ntawm pab pawg neeg kuaj Bercovici yuav raug xa mus rau Chaw Nres Nkoj Thoob Ntiaj Teb, uas yuav muaj kev sim ua ntau yam los pab kom cov neeg caij nkoj tsim thiab kho cov lo ntsiab muag hauv qhov chaw.Ua ntej ntawd, kev sim yuav tau ua nyob rau hauv Florida lub asthiv no los ntsuas qhov ua tau ntawm kev tsim cov lo ntsiab muag zoo nyob rau hauv microgravity yam tsis tas yuav muaj cov kua buoyant.
Lub Fluid Telescope Experiment (FLUTE) tau ua rau ntawm lub dav hlau txo qis-txhua lub rooj zaum ntawm lub dav hlau no raug tshem tawm rau kev cob qhia cov neeg caij nkoj thiab tua xoom-lub ntiajteb txawj nqus scenes hauv cov yeeb yaj kiab.Los ntawm maneuvering nyob rau hauv daim ntawv ntawm ib tug antiparabola-ascending thiab ces ntog dawb-microgravity tej yam kev mob yog tsim nyob rau hauv lub aircraft rau ib tug luv luv lub sij hawm ntawm lub sij hawm."Nws hu ua 'vomit comet' rau qhov laj thawj zoo," Berkovic hais nrog luag nyav.Lub caij nplooj zeeg dawb yuav kav ntev li 20 vib nas this, uas lub ntiajteb txawj nqus ntawm lub dav hlau nyob ze rau xoom.Nyob rau lub sijhawm no, cov kws tshawb fawb yuav sim ua kom lub lens ua kua thiab ntsuas los ua pov thawj tias qhov zoo ntawm lub lens yog qhov zoo txaus, tom qab ntawd lub dav hlau yuav ncaj, lub ntiajteb txawj nqus tau zoo tag nrho, thiab lub lens yuav dhau los ua dej ntws.
Qhov kev sim no tau teem sijhawm rau ob lub davhlau rau hnub Thursday thiab Friday, txhua qhov muaj 30 parabolas.Bercovici thiab cov tswv cuab feem ntau ntawm pab pawg kuaj, suav nrog Elgarisi thiab Luria, thiab Frumkin los ntawm Massachusetts Institute of Technology yuav tuaj.
Thaum kuv mus ntsib Technion Laboratory, qhov kev zoo siab tau dhau mus.Muaj 60 lub thawv ntawv rau hauv pem teb, uas muaj 60 tus kheej ua cov khoom siv me me rau kev sim.Luria tab tom ua qhov kawg thiab kawg-feeb kev txhim kho rau lub tshuab computer uas nws tau tsim los ntsuas qhov kev ua tau zoo ntawm lub lens.
Nyob rau tib lub sijhawm, pab pawg tab tom ua lub sijhawm ua haujlwm ua ntej lub sijhawm tseem ceeb.Ib pab neeg tau sawv ntsug nrog lub moos nres, thiab lwm tus muaj 20 vib nas this los tua.Ntawm lub dav hlau nws tus kheej, cov xwm txheej yuav phem dua, tshwj xeeb tshaj yog tom qab ob peb lub caij nplooj zeeg dawb thiab nce toj nqa hauv qab lub ntiajteb txawj nqus.
Nws tsis yog pab pawg Technion nkaus xwb.Baraban, tus thawj coj tshawb fawb ntawm NASA's Flute Experiment, hais rau Haaretz, "Txoj kev ua kua dej tuaj yeem ua rau lub tshuab tsom iav muaj zog nrog qhov apertures ntawm kaum lossis ntau pua meters.Piv txwv li, xws li telescopes tuaj yeem saib ncaj qha rau ib puag ncig ntawm lwm lub hnub qub.Planet, pab txhawb kev soj ntsuam siab ntawm nws cov huab cua, thiab tseem tuaj yeem txheeb xyuas qhov loj ntawm qhov chaw.Txoj kev no tseem tuaj yeem ua rau lwm qhov chaw siv, xws li cov khoom siv kho qhov muag zoo rau kev sau qoob loo thiab kev sib kis, cov cuab yeej tshawb fawb, thiab cov cuab yeej siv kho mob chaw tsim khoom-yog li ua lub luag haujlwm tseem ceeb hauv kev lag luam tawm tshiab. "
Tsis ntev ua ntej nce lub dav hlau thiab pib taug txuj kev nyuaj ntawm nws lub neej, Berkovic nres ib pliag hauv kev xav tsis thoob."Kuv pheej nug kuv tus kheej vim li cas tsis muaj leej twg xav txog qhov no ua ntej," nws hais."Txhua zaus kuv mus rau lub rooj sib tham, kuv ntshai tias ib tug neeg yuav sawv thiab hais tias qee tus kws tshawb fawb Lavxias tau ua qhov no 60 xyoo dhau los.Tom qab tag nrho, nws yog ib txoj hauv kev yooj yim.
