Sida dadka bartay in ay tiriyaan? Sida dadka ay barteen in ay tiriyaan in maskaxdaada?

naftiisa oo dhan, oo nin waluba wuxuu had iyo jeer waa wax ay wax ku bartaan, iyo aqoonta helay waqti cayiman ka dib u muuqdaan kuwo si dabiici ah in loo arko inay yihiin xaqiiqo dhab ah oo la yaqaan. Madaxa ma aha xitaa gurguurta, Fikirka ku jira: sida ay u dhan bilaabeen? Sida dadka ay barteen in ay tiriyaan iyo waqtiga sheegtid? Sidee bulshada dheer ayaa u yimid in ay ogaadaan in ku dhow wax walba ku xiran yahay tirooyinka ee dunida?

Sida dadka bartay in ay tiriyaan waqtiga

Waa in dunida casriga ah 365 maalmood sannadkii, 30 maalmood bil kasta iyo 24 saacadood maalintii waa xaqiiqo dhab ah oo dabiici ah. Markii hore, marka waxaa jiray aqoon lahayn oo ku saabsan qadarka wakhti qof ahaa ku qanacsanayn qaabka ay abuurtay si madax-bannaan, oo waxay ka dhigan tahay, waayo, taasu waa qorraxda. On kasta oo dusha rakibay dial la Calaamadayn iyo tiir, kaas oo hooska waxaa circumferentially dhaqaaqay. Dadka Caadaystay xaaladaha cimilada waa faa'iido weyn ee qalab noocan oo kale ah: Samada cadarka iyo daruuro leh oo uma oggolaanin go'aanka waqti. analoogga ah qaab-dhismeedka noocan oo kale ah ee dunida maanta waa saacad, ayaa laftiisa la aasaasay sida Misbaax oo ay noqoto wax lagama maarmaan ah in nolosha qofka.

Waqtiga xiddigaha, biyo, iyo dab

Star - astaanta hindiga iyo riyooyin oo wax fog oo qurux badan, u adeegay sidii nooc ka mid ah ahayn tilmaame waqtiga lagu jiro habeenkii ah. Si taas ayaa abuurtay map star, on taas oo cabbirka dhacay iyadoo adeegsanayo qalab transit ah.

Waxa intaa dheer in saacadaha qoraxda oo hugaaminaya, shiidaa dadka oo dhan caan ah oo kala duwan oo kaliya in qaab-dhismeedka, halkii ballaaran u isticmaali bandhigaa biyaha oo wakiil ka taangi cylindrical, kaas oo biyo lagu tiftifqay dropwise. Taasi waa tirada biyo waqti dadka qiyaas tiftifqay-off. saacadaha Kuwaasu waxay ahaayeen caanka ah ee Masar, Rome, Baabuloon. Nin barteen in ay qaataan waqti ay ku Asia? Halkan, in nooca aqueous-ah qalabka loo isticmaalo mabda'a dambe: markabka sabayn waxaa ka buuxsami doona biyo socda iyada oo loo marayo godka yar.

Isku dayga in ay keenaan nolosha biyo ma aha oo kaliya, laakiin sidoo kale element dabka, dadka sidoo kale la iman watch dabka, kuwaas oo qaatay ay asal ahaan in Shiinaha, waxaana ay badiyeen caan muddo in Yurub oo dhan. The salaysan qalabka, la qeexo wakhtiguna wuxuu ahaa wax guban kara (foomka of ulo ama galool) iyo kubadaha biraha ku lifaaqan, ka dhicin at qayb ka mid ah waxyaabaha sari. In Europe, inta badan loo isticmaalo saacadaha shumac, doorbiday ay ilayska iyo wicking. Time waxa go'aaminaya tirada wax la gubo. Gaar ahaan ku baahday jeedo oo kuwanuna waxay ahaayeen in kaniisadaha iyo Macaabidda Yuhuud.

Aqrisid - casriga kibir Marmarka

Dabcan, ugu caansan ahaayeen aqrisid ah, kaas oo la si firfircoon loo isticmaalaa in lagu fuliyo hawlihiisa ugu weyn, iyo sidoo kale waxyaabaha madaxtooyada. Sax waqtiga computable in qalabka noocan ah waxay ku xiran tahay ciid tayada, waxa go'aaminaya midayso ee flowability.

Taariikhda dhacdo of science tirinta

waqti Understanding in tilmaamayaasha ay taranta waa sababta keeno tiro barashada iyo xisaabta. Iyo taariikhda account asal ahaan waa sidaas dheer, in u muuqataa sida sheeko cirfiid a. Sida dadka bartay in ay tiriyaan? qarniyo badan ka hor, Dadka ku noolaa qabiil keentay qaab nololeed bulshaawiyiin, dharka ee harkaha xoolaha dhintay, iyo quudin by xaqiiqada ah in wakiilada ay naftaada ka heli karto.

Siday u kala horreeyaan, iyo qalab iyo gargaare u noolaadaan iyo wax soo saarka cuntada waa ka ugu fudud qalab, ulo iyo dhagaxyo. Waxaa laga yaabaa in khatarta joogtada ah iyo baahida loo qabo in wax soo saarka cuntada ayaa noqotay wadadii weyn ku baahida loo qabo biil in aannu mar Ogayn waxaa kaliya sida xaqiiqada ah dabiiciga ah, laakiin sidoo kale fududeeyay iyadoo la kaashanayo of technology casriga ah computer.

Mid ka mid ah, laba, iyo dad badan oo

Fikradda marka hore in loola jeedaa tirada iyo sharxaan sida dadka ay barteen in ay tiriyaan, waxay ahaayeen "mid ka mid ah" iyo "badan". "Mid ka mid ah" - si gooni gooni ah loo qoondeeyay si waafaqsan shuruudaha gaar ah ama maado: Hogaamiyaha baakada, hadhuudh dhegta, iwm "In badan" - mass wadarta, taas oo ku xiran yahay.

Xaaladan oo ah "laba", taasoo la micno ah "laba": indhaha, dhegaha, wixii baabacooyinka ku, baalasheeda, gacanta, sharxaysaa sida dadka bartay in ay tiriyaan in times of tiro aan jirin. Ka hadalka ku saabsan labada shinbiraha qabtay, ugaadhsadaha uga jiray uu u tilmaamay in indhihiisa, sidaas sharxaya tirada koobab.

In tirinta sayniska dunida qadiimiga ah waxaa jiray horumar tartiib ah: ayaa hore u ogaan lahaa tirada "mid ka mid ah", "laba" iyo "badan". Si dhakhso ah nin waxa noqday of mass guud loo qoondeeyo saddex, afar, shan ama in ka badan maadooyinka yimid, oo tirada this magaca lahayn, iyo sharxay sida lacagta loo yaqaan waqtiga tirada :. "2" iyo "1" Tusaale ahaan, "3" - waa "1" iyo "2" wadar ahaan; "4" - wadarta "2" iyo "2", iyo "5" - "2", "2" iyo "1" wada. In Tibet, tirada "2" waa baal ee Hindiya - indhaha, dadyowga qaar ka mid ah "1" - waa dayaxa, "5" - gacanta. In uu yahay, tiro kasta oo ay ahayd aragtida muuqaalka ugu horeysay israacinayo kahor intuuna horyaalka.

Arkayay lagama maarmaan muhiim ah

Sida dadka ay barteen in ay tiriyaan, haddii awood u leh inay "farshaxanka" marxalad kasta oo horumarka aadanaha uu noqdo muhiim? In geeddi-socodka ah ee ugaarsiga marka bahalka hareereysan ugaadhsadaha sare waxaa looga baahan yahay inay meel dadka xaq u leeyihiin in ay qaataan xayawaanka ee giraanta. Si arrintan loo sameeyo, ayuu tusay on faraha, isaga oo meesha iyo sida badan dadka waxay u baahan yihiin in ay qaataan jagada doonayo ..

In ganacsiga, si loogu magacaabo qiimaha sidoo kale codsatay faraha xisaabta (iyo faraha lugeed, haddii kharashka ahaa sare). Tusaale ahaan, is-dhaafsiga by waran on harkaha xoolaha sameeyey, iibiyaha waa inuu gacanta saaraa dhulka saaray oo muujisay in hore ee far kasta waxaa looga baahan yahay in ay ku riday maqaarka. By habka, farta laabanto tusinaysaa dheeriga ah, iyo kordhinta - goynta. Waxay ahayd tusaalooyinka xisaabta ugu horeysay sharxaya sida dadkii hore ka bartay inay tiriyaan ee la soo dhaafay ka fog.

sayniska tirinta ee dalal kala duwan

Waddamo badan ayaa raajiyey in ay taariikh, nooc ka mid ah sida ay dadka u barteen in ay tiriyaan, ayaa weli la isticmaalayo dhaxalka ee la soo dhaafay, in Japan iyo Shiinaha isticmaalka qoyska waxaa loo arkaa shan iyo toban toban, ee England iyo France - labaataneeyada.

Sida dadka bartay in ay tiriyaan? Halkee tirada iyo lambarada sameeyey? Habka koowaad ee tiro qoraal ahaayeen noqtay on geedaha iyo kuus kuus xirashada on xadhkihii.

Masriyiintii qadiimiga, iyagoo muujinayay in tallaabo kasta oo qaab sawirada on caw ah, sida tirooyinka sida aan la duubay. The deggan oo tiro Rome qadiimiga ah loo qoondeeyey by kusiga. Sayidka «Waxaan» - waa mid ka mid, «V» - burush image ka ridday xagga farta, halkii ay shanta farood ku haysta muuqashadii la fududeeyay, "X" - laba shan farood, wada duceysanayaan.

Iyada oo agaa of waraaqaha si loogu yeero Lambarada bilaabay in ay isticmaalaan xarfaha. Tusaale ahaan: B-

Iyada oo agaa of waraaqaha si loogu yeero Lambarada bilaabay in ay isticmaalaan xarfaha. Tusaale ahaan: B - waa "2", T - "3" M - "4" E - "5". In la kala saaro waraaqaha iyo tiro ka badan la soo dhaafay kiciyey icon ee loo yaqaan "Titley." Habka ma ahaa mid aad u sahlan, tan iyo markii aan la oggol yahay in ay qoraan tiro badan. Waqti ka, dadkii waxay bilaabeen inay sooci tirada waraaqaha iyo si gooni gooni ah qaatay, iyadoo aan loo eegin mawduuca.

Modern tiro Carabi, kaas oo si ballaaran yihiin meel walba loo isticmaalo maanta, ayaa lagu soo hindiseen in Hindiya, iyo in dalkeena lagu codsatay in qarnigii 18aad. Waxay lagama badin caan iyo lambarada Roman, ilaa maantadan la joogo helay on watch dial ah, oo loo isticmaalo si ay u aqoonsadaan qarniyadii iyo cutubyada in buugaagta.

biilasha jidka sharafta Baydka Baabuloon, halkaas oo loogu talagalay 6000 sano BC horeba la sameeyay diiwaanada xisaabta ee ganacsiga. Entries noocan ah ka muujinayaa images (characters) ee foomka of cufayo siman oo toosan cidhiidhi ah, sidaa darteed magaca "cuneiform" ah.

unit ayaa waxaa loo qoondeeyey mid ka mid ah wasladdii, godkee - laba iyo wixii la mid ah. Tirada "10" qoondeeyey waslad ballaadhan iyo magac gaar ah. Its talinaysay xisaabta Baabuloon la kulmeen intii lagu boqornimadii King Hammurabi. Ilaha qoraal ah waqtiga helay caddaymo ah sida ay dadka u barteen in ay qori iyo akhri, muddo dheer ka hor times our. Tani qoro hawlaha Kombuyuutarada adag, iyo sidoo kale xalka of isleegyo saablay oo cubic.

Sidee in ay bartaan sida loo tiriyo in maankiinna

Haddii hawlaha adag sida ka hooseeyeen xoogga awowayaashayo, qarniga casriga ah ee account xisaabeed, mar hagaagay oo badan oo maskaxda weyn, waa in aanay noqon si gaar ah u adag. Si kastaba ha ahaatee, helitaanka kombiyuutarada, awoodda in ay soo saaraan tallaabo digital halkii qof, aad bay u fududeeyaa shaqada maskaxda doonana. Sidaa darteed, account afka ah, waxay ka caawisaa horumarinta xusuusta iyo tababar xirfadaha, waa leedahay mid ka mid ah. Barashada noocan oo kale ah hawlaha maskaxda noqon doono mid guuleysta, haddii la joogo:

• awoodda, taas oo si wadajir ah ula fiirsashada maskaxda si ay u caawiyaan diiradda saaraan hawsha at gacanta iyo maskaxda ku hayso tirada adag;
• aqoonta qaaciidooyinka, keenaya hawlaha computer istareexsan soo saaray;
• dhaqanka kaas oo, wada jir ah ula tababar joogto ah oo noo ogolaadaa in la horumariyo iyo in la wanaajiyo xirfadaha.

Tusaalooyinka account maskaxda fudud

, Kala-gooyaan, tarmeen iyo qaybiyaan tirooyinka iyadoon la sameyn wax diiwaanka on warqad iyo ma isticmaalaya calculators waa SNAP ah. Halkan waxaa ku qoran dhowr tusaale oo ku saabsan sida si ay u bartaan sida loo tiriyo in maankiinna dhib badan oo aan:

Isku dhufashada by 4

hab fudud oo dadka tirada waa loo laablaabi by 2 iyo natiijada waxaa mar kale u labeeyay. Tusaale ahaan:

* 35 4 = 35 * 2 = 70 * 2 = 140

Isku dhufashada by 11

Lambar tiro laba rugle, lagu dhuftay 11, sida ay ugu baahan yahay inuu u dhaqaaqo marka laga reebo.

Tusaale ahaan:

48 * 11 = 4, iyo 8 * 11

Markaas tirada lambar looga baahan yahay inay isku laab, kiiskan 4 iyo 8, iyo natiijada noqon doontaa jawaab. Waxaa muhiim ah in la xasuusto in haddii natiijada summation waa tiro laba god ah, kaliya aad u baahan tahay inuu ka tago mid ka mid ah, iyo in tobanaan ku dar 1.

4 (12) 8 = 5 2 8 = 528. Taasi waa, natiijada ka helay 12 cutub ka tagay - waa 2, iyo mid ka mid ah toban daray.

U qeybi 5

Si aad u saamayn this ma keenin wax dhib, waxa loo baahan yahay in la kordhiyo tirada qeybtii oo guurto comma in ay hal god ka hor.

Tusaale ahaan:

125/5 = 125 * 2 = 250 (mowjadda dhibic) = 25

Qaybiyaan 50

Xaaladdan oo kale, tilmaantii la mid tahay: tirada lagu dhufto 2 iyo qaybiyey 100.

600/50 = 600 * 2/100 = 12

Qaybiyaan 25

Tirada tarmaan by 4 iyo qaybiyey 100.

700/25 = 700 * 4/100 = 28

Isku geynta iyo kala goynta ee tirooyinka caadiga ah

At Intaa waxaa dheer ee tirooyinka caadiga ah waa inuu ogaadaa trick this, in haddii mid ka mid ah shuruudaha in la kordhiyo tirada gaar ah (ay fududaato in account), tiro isku mid ah waa in laga jaraa ka natiijada.

Tusaale ahaan:

787 + 193 = (787 + 193+ 7 (waayo, soo aruurinta 193 200)) - 7 = (787 + 200) - 980 = 7
