Logarithmic wolamulira - waukulu kompyuta wagawo wa XX atumwi

Mu m'badwo uno wa makompyuta anapezazo kwambiri pa angagwiritse luso ndi makina kwathunthu, akatswiri zitha alowa ndi magawo wosuta-wochezeka mawonekedwe chofunika.

XX m'ma otchedwa zinthu zosiyana. Icho chinali atomiki ndi danga, ndi zambiri. Opanga ndege angwiro ndegeyo, ndipo ankachita biplanes womangika mu mofulumira MiGs supersonic, "ngatimadzi" ndi "Phantoms." Chimphona ndege onyamula ndi sitima zankhondo anayamba kukasambira m'nyanja ndi m'nyanja pa M'madera a zitunda zonse. Pa Los Alamos (New Mexico) anayesedwa bomba la atomiki, ndi Obninsk pafupi Moscow, anayamba kupereka woyamba mphamvu nyukiliya. Roketi anasangalala zimapikukira m'mwamba ...

Kodi atomiki bomba roketi ndi ndege ndege?

mbiri yakale kusonyeza ndondomeko ya ntchito pa zinthu zomwe takwaniritsa izi. Asayansi ndi akatswiri mu malaya woyera ataima pa matabwa zojambula, ndipo atakhala pa tebulo chosaneneka zojambula, kutulutsa zovuta anapezazo luso ndi sayansi pa kuwonjezera makina. Nthawizina manja a Tupolev, Kurchatov wonena kapena Mwadzidzidzi chinthu chosadziwika kwa masiku mnyamata - filimu ulamuliro. Photos of amene achinyamata wadutsa mu zaka nkhondoyo, mpaka 80s, komanso olembedwa phunziro nemudreny bwino m'malo mwa Chiwerengero pamene kuphunzira pa anayambitsa kapena maphunziro kusukulu. Ndipo nkhani yolembedwa komanso kukhulupirira, pa rodnenky.

Pa zifukwa ziti zoti lonse logarithmic?

Mfundo zikuluzikulu za chinthu ichi matabwa mosamala kuzilemba ndi woyera lonse yokhuthala zochokera maziko logarithmic, monga dzina lake likunenera. More ndendende, pa logarithm wamba. Pajatu aliyense amene waphunzitsa masamu apamwamba, amadziwa kuti ndalama zawo ndi wofanana ndi logarithm cha mankhwala, choncho bwino chikubweretsa magawano ndi mbali kusuntha, samalani kuti chulutsa (choncho magawano), squaring (ndi muzu Tingafinye) adzakhala nkhani yamasewera.

Logarithmic mzere yafala m'zaka za m'ma XIX, pamene chida chachikulu kuwerengetsera anali ambiri masiku. Izi Kutulukira - ndi godsend kwenikweni kwa ndiye asayansi ndi akatswiri. Osati kamodzi iwo asanaganize mmene ntchito chipangizo ichi. Kuti mudziwe zidule onse ndi kuzindikira umatha limagwirira zonse, mafani atsopano kuwerenga tiyenera kuwerenga ankamvetsa wapadera, mphamvu yokwanira. Koma zinali zopindulitsa.

Olamulira osiyana, ngakhale wozungulira

Koma mwayi waukulu umene ali logarithmic lonse - kuphweka ake choncho kudalirika. Poyerekeza ndi njira zina za malipiro (malinga ngati panalibe toŵerengera) ntchito kunachitika mofulumira kwambiri. Koma pali mfundo zimene sayenera munayiwala. Likhoza kuchita anapezazo ndi mantissas, i.e. lonse (mpaka naini) ndi gawo fractional wa nambala ndi awiri (atatu, imodzi masomphenya zabwino kwambiri) decimals. Dongosolo la manambala ofunika kukumbukila. Panalinso drawback wina. Logarithmic mzere yaing'ono, ya m'manja chipangizo komanso n'zovuta kuitana - 30 cm, pambuyo pa zonse.

Koma kukula sichikwiya chopinga kwa ofunsa maganizo. Kwa amene chifukwa ntchito zawo ayenera kuwerenga chipangizo nthawi zonse ndi inu, kupangidwa ndi logarithmic osiyanasiyana yaying'ono. Imbani muvi anam'patsa kufanana kwa koloko, ndi ena zitsanzo ndi chronometers mtengo anali pa oyimba ake. Kumene, mwayi pogwiritsa ndi molondola penapake wolephera magawo lolingana kwa mzere chakale, koma anali Sizotheka kunyamula mu thumba lanu. Ndipo ndi azisangalala amasangalala taonani!
