Umlawuli Window - iyunithi computing engundoqo kwinkulungwane XX

Kule ubudala bugcisa computer, izibalo ezininzi nokuyila bugcisa nokuhambisa ngokupheleleyo, iinjineli Ungangena kuphela ngokusebenzisa i parameters kumsebenzisi-ongumhlobo interface ezifunekayo.

XX leminyaka ebizwa izinto ezahlukeneyo. Loo atomic nesithuba, kunye nolwazi. Moya, nigqibelele lo moya, baza babuya ngaphandle biplanes kunzima MiGs supersonic ngokukhawuleza, "isanga" yaye "wabo." iziphathi-moya Giant ngwenya baqalisa ukuba uyihlole kweelwandle neelwandlekazi kuwo onke ezinezinga. E Los Alamos (New Mexico) kuvavanywe i ukuqhushumba atom, yaye Obninsk kufuphi Moscow, waqala ukunika amandla lokuqala enyukliya. Irula lenyuka esibhakabhakeni ...

Njani na ukuqhushumba atomic ngexabiso kunye jet-moya?

iingxelo zembali zibonisa ukuba inkqubo esebenza ngale mpumelelo. Izazinzulu neenjineli beneengubo ezimhlophe emi iibhodi zokuzoba, kwaye ehleli etafileni ugcwele ngemizobo, ukuvelisa izibalo entsonkothileyo yobugcisa kunye lwenzululwazi wodibaniso koomatshini. Ngamanye amaxesha ezandleni Tupolev, Kurchatov Teller okanye ngequbuliso ivela into engaziwayo umfana mihla - rule kwisilayidi. Iifoto abo ulutsha sele kudlule kule minyaka yasemva kwemfazwe, ekunene ukuya kwi-80, nawo lo mbandela nemudreny, ithatha ngempumelelo ikhalityhuleyitha ngelixa ukufunda kweli ziko okanye onesidanga yesikolo. Kwaye ke thesis nayo yakholwa kulo, phezu rodnenky.

Uyintoni na amalungiselelo isikali lwe logarithm olusezantsi?

Lo mgaqo iphambili yale esisesandleni, baxhoma ngocoselelo kunye abasakhasayo celluloid emhlophe ngokusekelwe qho lwe logarithm olusezantsi, njengokuba igama lixela. Okunye ncam, phezu logarithm eqhelekileyo. Ngapha koko, nabani na othe wafundisa uhlobo oluphambili, uyazi ukuba bawadibanise lilingana logarithm ye imveliso kunye, ngoko ke, ebangela kakuhle hlula by ezihambayo, bangaqinisekisa ukuba nophinda-phindo (kwaye ke kwicandelo), squaring (kwaye ingcambu Khipha) aya kuba yinto elula.

umgca Window iye yenziwa kwinkulungwane XIX, xa isixhobo esingundoqo izibalo yaba amanqaku njengesiqhelo. Olu qambo - a oyinto ngokwenene ngoko izazinzulu neenjineli. Hayi kanye Babegqibe ukuba usebenzise indlela kule fowuni. Ukuze ufunde onke amaqhinga kunye ukubona ezingaba wayo indlela ngokupheleleyo, abalandeli ezintsha ukubala kufuneka ufunde nezibonelelo ezikhethekileyo, umthamo owaneleyo. Kodwa ke, kulungile.

Iirula ezahlukeneyo, ngeenxa

Noko ke, uncedo engundoqo iyileyo iye isikali lwe logarithm olusezantsi - alula kunye ngoko nokuthembeka. Xa kuthelekiswa nezinye iindlela zokuhlawula (logama nje kwakungekho iikhalityhuleyitha) imisebenzi bathwalwa ngaphandle kakhulu ngokukhawuleza. Kodwa kukho iingongoma asimele sikubethe ngoyaba. Ayikwazi ukwenza kuphela izibalo kunye mantissas, ngamanye lonke (elithoba) nesahlulo iqhezu inani, kunye (, ngumbono omhle kakhulu emithathu) needesimali emibini. Ukulandelelana kwamanani ukuze sigcine engqondweni. Kwabakho elinye ethile. umgca Window isixhobo encinane, i Pilot kodwa kunzima ukubiza - 30 cm, emva bonke.

Kodwa ke ubukhulu ingabi umqobo ukuba ukwazi iingqondo. Kuba abo ngenxa yokuba imisebenzi yabo kufuneka babale isixhobo usoloko nawe, yaqanjwa uluhlu lwe logarithm olusezantsi compact. Cofa utolo wamnika ufana ngaashi, yaye ezinye bemizekelo chronometers eninzi Sahlala kwi dial yayo. Kakade ke, amathuba esi sixhobo nokuchaneka wayo ngandlel nganto elinediski parameters lomgca yamandulo, kodwa akusoloko kusenzeka ukuba uthwale epokothweni yakho. Kwaye ngakumbi nezamkelekileyo sikholisa jonga!
