Mwina mumadziwa magalasi, koma mumadziwa chiyambi cha galasi?Galasi sinayambike masiku ano, koma ku Egypt zaka 4000 zapitazo.
M’masiku amenewo, anthu ankasankha mchere winawake kenako n’kuusungunula pa kutentha kwambiri n’kuuika m’mawonekedwe ake, zomwe zimachititsa kuti magalasi ayambike.Komabe, galasilo silinali lowoneka bwino monga momwe liriri lero, ndipo pambuyo pake, pamene luso lamakono linapita patsogolo, galasi lamakono linapangidwa.
Akatswiri ena ofukula zinthu zakale awona galasi kuyambira zaka zikwi zambiri zapitazo, ndipo mapangidwe ake ndi atsatanetsatane.Zimenezi zadzutsa chidwi cha anthu ambiri ponena kuti galasi lakhala ndi moyo kwa zaka zikwi zambiri popanda kunyonyotsoka m’chilengedwe.Kotero kuchokera ku lingaliro la sayansi, mpaka liti tingaponye botolo lagalasi kuthengo ndikukhalapo mu chilengedwe?
Pali chiphunzitso chakuti chikhoza kukhalapo kwa zaka mamiliyoni ambiri, chomwe sichiri chongopeka koma chiri ndi chowonadi chake.
Galasi yokhazikika
Zotengera zambiri zomwe zimagwiritsidwa ntchito posungira mankhwala, mwachitsanzo, zimapangidwa ndi galasi.Zina mwa izo zingayambitse ngozi ngati zitatayika, ndipo galasi, ngakhale lolimba, ndi losalimba ndipo likhoza kusweka ngati litagwetsedwa pansi.
Ngati mankhwalawa ndi owopsa, bwanji kugwiritsa ntchito galasi ngati chidebe?Kodi sikungakhale bwino kugwiritsa ntchito zitsulo zosapanga dzimbiri, zomwe sizimagwa ndi dzimbiri?
Izi zili choncho chifukwa galasi ndi lokhazikika, mwakuthupi komanso mwakuthupi, ndipo ndilopambana kuposa zipangizo zonse.Mwakuthupi, galasi silisweka pa kutentha kwakukulu kapena kutsika.Kaya m'chilimwe kapena m'nyengo yozizira, galasi imakhala yolimba.
Pankhani ya kukhazikika kwa mankhwala, galasi imakhalanso yolimba kwambiri kuposa zitsulo monga zitsulo zosapanga dzimbiri.Ma asidi ndi zinthu zamchere sizingawononge magalasi akaikidwa mu galasi.Komabe, ngati zitsulo zosapanga dzimbiri zinagwiritsidwa ntchito m’malo mwake, sipanatenge nthaŵi yaitali kuti chombocho chisungunuke.Ngakhale galasi akuti ndi losavuta kusweka, limakhalanso lotetezeka ngati litasungidwa bwino.
Zinyalala galasi mu chilengedwe
Chifukwa galasi ndi lokhazikika, ndizovuta kwambiri kutaya galasi lotayirira mu chilengedwe kuti liwononge mwachibadwa.Nthawi zambiri takhala tikumva kale kuti mapulasitiki ndi ovuta kuwononga chilengedwe, ngakhale patapita zaka zambiri kapena zaka zambiri.
Koma nthawi ino si kanthu poyerekeza ndi galasi.
Malinga ndi kafukufuku wamakono, zingatenge zaka mamiliyoni ambiri kuti galasi liwonongeke kwathunthu.
Pali tizilombo tochuluka m'chilengedwe, ndipo tizilombo tosiyanasiyana timakhala ndi zizolowezi ndi zosowa zosiyanasiyana.Komabe, tizilombo toyambitsa matenda sitidya magalasi, choncho palibe chifukwa choganizira kuti magalasi angawonongeke ndi tizilombo toyambitsa matenda.
Njira inanso yomwe chilengedwe chimayipitsa zinthu chimatchedwa oxidation, monga momwe pulasitiki yoyera ikaponyedwa m'chilengedwe, m'kupita kwa nthawi pulasitikiyo imakhala ndi mtundu wachikasu.Pulasitikiyo idzakhala yophwanyika ndi kusweka mpaka itagwa pansi, ndiye mphamvu ya okosijeni ya chilengedwe.
Ngakhale chitsulo chowoneka cholimba chimakhala chofooka poyang'anizana ndi okosijeni, koma galasi imagonjetsedwa kwambiri ndi okosijeni.Oxygen sangathe kuchita kalikonse ngakhale atayikidwa m'chilengedwe, chifukwa chake n'zosatheka kuwononga galasi mu nthawi yochepa.
Magombe osangalatsa agalasi
Kodi nchifukwa ninji magulu a zachilengedwe samatsutsa kuti magalasi aponyedwe m’chilengedwe pamene sangathe kunyonyotsoka?Chifukwa chakuti chinthucho sichimawononga kwambiri chilengedwe, chimakhala chimodzimodzi chikaponyedwa m’madzi ndipo chimakhala chimodzimodzi chikaponyedwa pamtunda, ndipo sichidzawola kwa zaka masauzande.
Malo ena adzabwezeretsanso magalasi ogwiritsidwa ntchito, mwachitsanzo, mabotolo amagalasi adzadzazidwanso ndi zakumwa kapena kusungunuka kuti aponyedwe china.Koma galasi lobwezeretsanso ndilokwera mtengo kwambiri ndipo poyamba botolo lagalasi limayenera kutsukidwa lisanadzazidwe ndi kugwiritsidwanso ntchito.
Pambuyo pake, luso laukadaulo litayamba kuyenda bwino, zidawonekeratu kuti kupanga botolo lagalasi lotsika mtengo kuposa kuligwiritsanso ntchito.Kubwezeretsanso mabotolo agalasi kunasiyidwa ndipo mabotolo opanda pake adasiyidwa ali pagombe.
Pamene mafunde akutsuka pamwamba pawo, mabotolo agalasi amawombana wina ndi mzake ndikumwaza zidutswazo pamphepete mwa nyanja, motero amapanga gombe la galasi.Zingaoneke ngati zingakanda manja ndi mapazi a anthu mosavuta, koma kunena zoona magombe ambiri a magalasi sathanso kuvulaza anthu.
Izi ndichifukwa choti miyala ikamapaka galasi m'mphepete mwake imakhala yosalala ndikutaya mphamvu yake yodulira.Anthu ena okonda zamalonda akugwiritsanso ntchito magombe agalasi ngati malo okopa alendo kuti apeze ndalama.
Galasi ngati gwero lamtsogolo
Pali kale magalasi otayira ambiri omwe amasonkhanitsidwa m'chilengedwe, ndipo pamene magalasi akupitiriza kupangidwa, kuchuluka kwa galasi lotayirira kudzakula kwambiri m'tsogolomu.
Asayansi ena amanena kuti m’tsogolo, ngati miyala yopangira magalasi ikasoŵa, galasi lotayirali lingakhale gwero.
Atakonzedwanso ndi kuponyedwa m'ng'anjo, galasi lotayirirali likhoza kuponyedwanso muzovala zamagalasi.Palibe chifukwa cha malo enieni osungiramo zinthu zamtsogolo, kaya poyera kapena m'nyumba yosungiramo katundu, chifukwa galasi ndi lokhazikika kwambiri.
Galasi losasinthika
Galasi wachita mbali yofunika kwambiri pa chitukuko cha anthu.Kale Aigupto ankapanga magalasi kuti azikongoletsa, koma kenako magalasi ankatha kupangidwa kukhala zotengera zosiyanasiyana.Galasiyo idakhala chinthu wamba bola simunaswe.
Pambuyo pake, njira zapadera zinagwiritsidwa ntchito kuti magalasi awoneke bwino kwambiri, zomwe zinapereka zofunikira kuti apange telescope.
Kupangidwa kwa makina oonera zakuthambo kunayambitsa nyengo ya kuyenda panyanja, ndipo kugwiritsira ntchito magalasi pa makina oonera zakuthambo a zakuthambo kunapangitsa kuti anthu amvetse bwino chilengedwe chonse.Ndizomveka kunena kuti teknoloji yathu sikanafika pamtunda umene uli nawo popanda galasi.
M'tsogolomu, galasi idzapitiriza kugwira ntchito yofunika kwambiri ndikukhala chinthu chosasinthika.
Galasi lapadera limagwiritsidwa ntchito pazinthu monga ma lasers, komanso zida za ndege.Ngakhale mafoni a m'manja omwe timagwiritsa ntchito asiya pulasitiki yosagwira ntchito ndikusintha magalasi a Corning kuti awonetse bwino.Pambuyo powerenga zowunikirazi, kodi mwadzidzidzi mumamva kuti galasi losawoneka bwino ndi lalitali komanso lamphamvu?
