• Zitsanzo za notation yasayansi

Pulogalamu ya Zolemba zasayansi, wotchedwanso notation kapena mawonekedwe wamba, imakupatsani mwayi wofotokozera manambala akulu kwambiri kapena ochepa kwambiri munjira yofupikitsa komanso yosavuta, yomwe imathandizira kulemba ndikuthandizira mukamafunika kuchita masamu ndi manambalawa kapena kuwaphatikizira muzinthu kapena ma equation.

Amakhulupirira kuti anali Archimedes yemwe adayambitsa njira zoyambirira zomwe zidapangitsa lingaliro la sayansi.

Pulogalamu yamanambala polemba sayansi zalembedwa ngati zotuluka ndi nambala yathunthu kapena decimal pakati pa 1 ndi 10 ndi mphamvu ya base 10.

Mwanjira imeneyi, notation yasayansi imayankha pamfundo zotsatirazi: n x 10^x o n x 10^-x. Monga njira yothandiza, titha kunena kuti kuti musinthe manambala opitilira 1 kukhala asayansi, muyenera kuyika comma pambuyo pa manambala oyamba ndikuwerengera zotulutsa kutengera malo angati kumanzere omwe adatsalira.

Kusintha ziwerengero zosakwana 1 kukhala sayansi, Muyenera kuyika comma pambuyo pa manambala achiwiri mpaka omaliza ndikuwerengera zotulutsa kutengera malo angati kumanzere omwe adatsalira, yofotokozedwa ngati yosalimbikitsa. Mu zitsanzo zomwe zaperekedwa pamwambapa, nambala ya Avogadro ikhala 6.022 × 10²³ ndipo kulemera kwa haidrojeni ndi 1.66 × 10^-23.

Manambala mu notation yasayansi amathanso kulembedwa ngati matchulidwe apadera. Mwachitsanzo, 4 × 10⁸ Zitha kulembedwa ngati 4e + 8.

Kuchulukitsa ziwerengero mu sayansi, muyenera chulukitsani manambala kumanzere, chotsalacho chimachulukitsidwa ndi 10 kukwezedwa mpaka kuchuluka kwa otulutsawo. Kuti mugawane ziwerengero mu sayansi, muyenera kugawa manambala omwe ali kumanzere, zotsatirazi zidachulukitsidwa ndi 10 zomwe zidakwezedwa ndikuchotsa omwe akutulutsa.

Zitsanzo za notation yasayansi

Nazi zitsanzo za ziwerengero za sayansi:
