Sinyatselo ngesinyatselo: Ntambama we-D’Alembert
Liyunithi linye etulu ngemuva kwekulahlekelwa, liyunithi linye phansi ngemuva kwekuwina, lokubovu kuko konkhe kujikeleta ekujikeleteni lokulikhulu. Luhlelo lolumnene kakhulu, nekutsi bumnene bubita malini.
Iseshini lelingisiwe ye-D’Alembert yekujikeleta lokungu-100 nga-$5 liyunithi ngalinye. Linani lelibhejwako lehla labuyela ku-$5 kasihlanu, lenyuka kancane kancane lafika ku-$80 ngesikhatsi lesibi, laphela ku-$55 iseshini yehlile nga-$40. Luhlelo loluva shengatsi kulingana kodvwa lolungesikho.
Hamba neluhlelo
Kulahlekelwa kwenyusa sinyatselo sinye. Kuwina kubuyisela emuva sinyatselo sinye.
Emanani labhejwako nemiphumela akumayunithi ekubheja lokusisekelo.

Umcondvo, longakaphakanyiswa ngu-d’Alembert kodvwa abekwa licala ngawo, utsi kuwina nekulahlekelwa kuyalingana, ngako kuko konkhe kubili kwekulahlekelwa kunye nekuwina kunye sitawuba ngetulu ngeliyunithi. Tibalo titsi lokubovu kuwina ku-48.65% wekujikeleta, ngako kulahlekelwa kwendlula kuwina cishe ngakunye kulamashumi lamane, futsi linani lelibhejwako lenyuka kancane kancane ngekuhamba kwesikhatsi.

Loko lokukhonjiswa yiseshini
I-D’Alembert iliphutsa lemgembuli lelibhalwe njengemtsetfo wekubheja: icabanga kutsi kuwina nekulahlekelwa kutawulingana masinyane kwanele kutsi linani lelibhejwako lehle futsi. Kuyalingana ekuhambeni kwesikhatsi lesidze ngekuhlanjululwa, hhayi ngekulungiswa, futsi linani lelibhejwako alinasizatfu sekubuyela eliyunithini linye. Luhlelo loluhamba kancane lolungenalo liwa, futsi kuhamba kancane kwalo yingako badlali balukholwa.

Kuyakhandza. Linani lelibhejwako lenyuka ngeliyunithi linye ekulahlekelweni ngakunye, hhayi ngekuphindza kabili, ngako kudzinga luchungechunge lolubi lolude kakhulu kufika emkhawulweni.

Lizinga lesisekelo lekucatsaniswa nalo konkhe kwenyuswa kwelinani.Fundza konkhe → emkhawulweni ngemuva kweluchungechunge lolubi. Nanoma ngumuphi umkhawulo ulungile; kute lowushintja inzuzo yelikhasino.
Nga-1754 watsi umsila uba nelitfuba lelikhulu ngemuva kweluchungechunge lwetinhloko. Bagembuli labavumelana naye baletsa luhlelo ngelibito lakhe. Bekatawuba nemahloni.
Lokuhlekisako
Luhlelo lolumnene kakhulu. Lukhuphuka kancane kancane esikhundleni sekuwa.
