He aha ka chronometer? 'Ike kiko'ī

Hō'ike ka'atikala e pili ana i kahi chronometer, nāna i no'ono'o, no ke aha i makemake'ia ai, a pehea e ho'ohana'ia ai kēia mea i kēia ao.

'O nā wā kahiko

Mai ka wā kahiko, ua'ike ka po'e i ka pono e koho pono i ka lō'ihi o ka manawa. A inā i ka wā o ka papahana kahiko me ka hana'ole i nā mea e like me ia, a laila, me ka hana'ana i kahi kaiaulu kaiaulu ke kaiapuni i kēia nīnau me ka ikaika nui. 'O ka nele o nā cloka a me nā mea'ē a'e no ka manawa kūpono, ua ho'oikaika loa ia no kekahi mau mea o ke ola. A inā'a'ohe pilikia me ka helu'ana o nā lā, pehea lā e'āpono ai i kahi hālāwai? 'O ka'oia'i'o, hiki iā'oe ke ho'okele i ka lā, akā'a'ole i pololei ke'ano o kēia mehana, a'a'ole maopopo i ke anuanu. No kēia mau kumu i ho'ā'o ai nā kānaka e hana i nā makelia a me nā analog.

'O nā'ano hana mua loa, i'ike'ia e nā kālaihonua, ua kapa'ia he clepsydra. He moku ia i holo malie ai ka wai, no ka mea, he moku e lele ana me ka mahele. 'Oia'i'o,'o ia mea kūpono i ka ana'ana i ke ka'ina manawa.

Akā, ma mua o ka ho'ohana'ana o ko mākou mau kūpuna i ka pale kaua, e'ike ana i ke'ano o ka malu o ka malu, e like me ka manawa o ka lā. 'Oi, ua ho'omaka'ia nā hola o ka hana ma'amau no ka manawa mua i ka huapalapala i hana'ia ma ka hopena o ka makahiki. He mea kālā, nui, a'a'ole hiki i nā mea a pau ke hā'awi iā lākou. 'Ae,'a'ohe pilikia e like me ia - ma ke kūlanakauhale ua kūkulu'ia kahi hale kia'i, kahi i kū ai ke uaki, a ua hiki i kekahi ke'ike i ka manawa.

Eia na'e, he mau hewa ko nā makelia o nā mana'o like'ole, a pēlā i ka makahiki 1731, ua kūkulu kahi kia'i kia'i Harrison i kahi chronometer. No laila he aha ka chronometer a he aha ke'ano?

Ka wehewehe

E like me nā hua'ōlelo,'o ka chronometer he kauka pololei loa me ka hapa li'ili'i loa. Ka mea, i hoʻohana 'ia ma kahi o ka manawa a me ka lōʻihi mea oi loa nui. Loa'a'ole ka mea'ole i ka lawe'ana i kēlā'ano no ka ho'ohana'ana i ka home.

Ma nā'ōlelo ma'alahi, eia nā māka'ika'i ma'amau,'o ia ke kumu o ka pololei, a ua pale'ia mai nā hapa kūpono'ole. No laila'o Harrison'a'ole'o ia ka mea ho'opuka o ka wati,'o ia wale nō ka mea i lawe i kā lākou mana'o a ho'opiha iā ia i kēlā manawa. No laila, ke'ike nei mākou he aha ka chronometer. Akā, ma hea kahi e ho'ohana'ia ai?

Ka ho'ohana

'O ka hopena nui loa o ia'ano, e like me ka manawa chronometer,'o ia ke kumukuai. No ka mea, ua lō'ihi ka lō'ihi o ka hana'ana, ke ho'ohālikelike'ia me nā māka'ika'i ma'amau. Eia na'e, i ka manawa ma hope iho, hiki i ka hale kia'i ke ho'ēmi i ko lākou kumukū'ai, a ua nui loa ka koi'ana o nā chronometers. 'O ka mua e loiloi iā lākou e like me ka mea e pono ai, he mau luina. I ia mau lā, ua hana'ia ka wehewehe o ka latitude a me longitude e ka lā, a ua pono ka chronometer pololei e ho'opa'a i ka manawa o ka puka'ana o ka lā a i ka napo'o o ka mālamalama. 'O ke'ano ma'amau,'o ka'oi loa aku o kēia i hana'ia,'o ka'oi aku o ka pololei o nā luina i ho'oholo i ko lākou wahi.

Ma hope mai, ua komo ka nui o nā'epekema i loko o ka'ōnaehana, e like me nā hi'ohi'ona, e pono e kākau pololei i kekahi mau hanana. No laila,'ike mākou he aha ka chronometer.

I kēia mau lā

Ua ho'ohana'ia kēia polokalamu no nā haneli he nui no ka ho'okele'ana i nā moku o ke ea a me nā moku moana, akā,'a'ole i ho'ohana pinepine'ia ka chronometer, koe wale nō he wahi waihona. I ka nui, e hoike ana oia i auou caiaiai ia ma ka hou pololei pōaka kiaʻiʻana. A'o ka mea nui,'o ka holo'ana o nā moku a me nā mokulele i lō'ihi ka manawa i ho'onohonoho'ia ma luna o nā leka uila a me nā pūnaewele aniani. Akā inā makemake'ia, hiki i kekahi ke kū'ai i kekahi mea e like me kahi chronometer. 'O ke kumukū'ai he nui loa ia, e like me ka nui, laikini, pololei a me ka mea nani. Eia kekahi la'ana, e kū'ai'ia he 31,000 Russian rubles e ke kope o ka palena manawa moana MX 6. 'O kahi māka lima lima a me ka pahu manawa manawa'o Ulysse Nardin e uku'ia mai 300,000,000. Akā,'o ke kumukū'ai o nā koho hou aku i ho'omaka'ia mai kahi o 1500 rubles.
