peb tuaj yeem teeb tsa tus nqi ntawm lub rooj zaum rooj zaum los ntawm $ x$ lub rooj zaum ntawm $ y$ thiab ob lub txaj los ntawm $ z$ yog li peb tau txais qhov system $ 20x16y12z = 19600 $ $ 15x12y9z = 15700 $ $ 12x10y6z = 11600$
1. pab nias lub rooj zaum ntawm lub rooj zaum nqaim, thov pab?
Saib seb koj puas tuaj yeem tshem tawm ob txhais ceg kom nws nqaim kom haum rau lub tsev
2. Qhov txawv ntawm ib tug theoretical physicist thiab ib tug armchair physicist yog dab tsi?
Ib tug armchair physicist yog tsis muaj txiaj ntsig. Lawv feem ntau yog cov uas hais lus lom zem xws li: "Saib, Kuv tsis tas yuav nkag siab lej, tsuas yog sib cav txog cov ntsiab lus!" "Koj yuav tsum tau qhib siab ntau dua txog lub aether." "Tsis muaj leej twg to taub quantum mechanics." thiab lwm yam. .
3. Ob lub fainting spell nyob rau hauv peb lub lis piam: Armchair kws kho mob, qhia kuv yog vim li cas?
Kuv muaj ntshav siab thiab kuv faint yooj yim. Kuv kuj npaum li. Kuv muaj ib yam dab tsi hu ua ... mitral valve prolaps? Kuv tau kawm txuj ci kev ua yeeb yam nrog ob tus kws phais plawv saum toj kawg nkaus hauv kuv lub nroog thiab lawv tau kuaj pom nws nyob hauv chav kawm. Lawv hais tias nws tshwm sim hauv cov neeg nyias nyias. Nco ntsoov nug tus kws kho mob yog tias koj ua tau. Koj txiv puas tau hais rau lawv tias koj muaj kev ntxhov siab yav dhau los?
4. Ib lub rooj zaum armchair kev xav txog vim li cas cov kob ntawm "Lost" yog li ntawd?
Hav North, Kuv ntseeg tias nws yog qhov sib npaug ntawm peb lub neej. "Lwm tus" - Peb tsis ntseeg cov neeg uas tsis zoo li peb! Thaum peb muaj teeb meem xws li kev tsiv teb tsaws chaw lossis Gays xav sib yuav lossis thov Vajtswv hauv tsev kawm ntawv - PEB YUAV TSUM TAU TXAIS! Lub "Island" - Tsis muaj ib tug yuav cawm tau lawv. Tsis muaj tsoom fwv, Tsis muaj niam, Tsis muaj tsev neeg - Nws nyob ntawm lawv thiab lawv tus kheej wits. Yuav ua li cas yog tias koj yog ib tug ntawm cov neeg nyob rau hauv nag xob nag cua Katrina los yog Tsunami nyob rau hauv Indonesia ntawm Christmas? Leej twg yuav nyob ntawd rau koj? "Lub ntsiab lus" - yuav ua li cas rau tag nrho cov ntawm lawv? Yuav ua li cas rau peb sawv daws? Peb muaj kev kub ntxhov nyob rau hauv Middle East, Teeb meem nrog Iran, Roj tsim lub teb chaws uas muaj ib tug strangle-tuav rau peb txhua tus .... Lawv yuav ua li cas? Tsuas yog kuv txoj kev xav, James hauv San Diego
5. Cov Tub Rog Tiag Tiag (tsis yog cov tub rog dag lub rooj zaum tub rog tshaj tawm hauv ntu no)?
Nyob rau hauv WW2 kuv yuav tau tibneeg hu tauj coob tua neeg (hauv lub teb chaws Yelemees) uas ua hauj lwm hauv qab nws ... Yog li ntawd, tsis muaj li cas ;)
6. Puas yog Is Nrias teb muaj ntau tshaj ntawm cov kws tshaj lij rooj zaum rooj zaum?
Yog thiab Tsis Yog vim Is Nrias teb yog ib lub teb chaws ntawm 1.2 billion ntxiv rau tib neeg. Peb muaj ntau tshaj ntawm txhua yam, zoo yuav luag txhua yam. Tsis ntau dhau Olympic puav pheej yeej, piv txwv li. Nyob rau hauv kev ceev ntiag tug ntawm peb cov chav nyob los yog nyob rau hauv lub tuam txhab ntawm cov phooj ywg nyob rau hauv tshuaj yej-tsev peb yeej ib txwm opined - ntawm cov teeb meem tsis tseem ceeb thiab ntawm cov teeb meem loj ntshuam. Tsis muaj qhov xav tsis thoob Amartya Sen tau sau txog Cov Neeg Qhab Asmeskas. Kev tshaj xov xwm tau ua rau kev nthuav qhia koj lub tswv yim yooj yim dua thiab peb tsuas yog ua kom zoo dua. Kab lis kev cai yeej ib txwm ua li ntawd nws tau txhawb ib tug neeg kom muaj kev xav. Yam tsawg kawg yog qhov xwm txheej yav dhau los. Koj yuav nco ntsoov Mahabharat muaj ntau zaus uas cov tub ntxhais hluas tau nug lawv cov kev xav, ib txwm ua ntej cov txwj laus kom lawv tsis txhob ntshai lossis yuam kom rov hais dua li cov txwj laus tau hais. Tu siab, tam sim no cov ntaub ntawv kawm thiab cov kev qhia thiab tsev neeg lub neej tsis txhawb kev ywj pheej tab sis mus rau lwm yam huab thiab tiv thaiv nws nyob rau hauv feem ntau. Kev nkag mus rau hauv is taws nem tsis pab tsawg tshaj plaws - koj tsis tas yuav ua kom koj lub siab xav, koj tuaj yeem nyeem cov lus uas lwm tus hais thiab siv nws kom ntseeg tau ntau zaus. Tsis yog vim peb kuj muaj ntau tus kws tshaj lij thiab cov neeg ua haujlwm tiag tiag - dua li cov pej xeem qhov khoom. Lawv tau pab txhawb ntau rau zej zog thiab daws teeb meem. Muaj ob peb tus tau ua tiav tawm tsam txhua qhov sib txawv. IMO qhov no tsis yog tshwj xeeb rau Is Nrias teb - tshwm sim thoob plaws ntiaj teb. Muaj ntau 'cov kws tshaj lij rooj zaum rooj zaum' ntau dua li 'cov kws tshaj lij' / xav tau' txhua hnub. Tsuas yog tias peb cov lej thiab nkag mus rau hauv xov xwm ua rau peb nrov nrov. Nyob rau hauv txhua rooj plaub, lub suab nrov yog ib tug heev Indian yam ntxwv.Confession: Kuv ib yam nkaus thiab yog ib tug armchair kws txawj ntawm ib tug xov tooj ntawm cov teeb meem. Yuav ua li cas? Peb tsuas yog zoo li ntawd xwb!
7. Puas yog armchair critics khiav tsov rog Iraq raws li xov xwm tshaj tawm?
Kuv tsis paub meej tias feem coob ntawm cov tub rog uas nyob hauv txoj cai tswjfwm saib cov xov xwm. Qee lub sij hawm ua raws li ib zaj dab neeg lawv yuav tab sis feem ntau ntawm cov neeg tsim cai tau nyeem cov xov xwm los ntawm cov ntawv xov xwm phab ntsa lossis Washington lub sij hawm los ntawm kuv qhov kev paub. Muaj ib qho kev tshaj tawm uas tsim los ntawm cov dab neeg xov xwm hu ua "Early Bird" uas tau nthuav tawm nyob ib puag ncig kom cov neeg tau txais xov xwm yam tsis muaj lwm yam crap pov rau hauv. Tau hais tias - Kuv xav tias qhov teeb meem feem ntau ntawm cov thawj coj muaj nyob hauv Iraq tshwj xeeb yog "Wishful think Syndrome" lawv ntseeg ib yam dab tsi los ua qhov teeb meem thiab txiav txim siab ntxiv qhov txiaj ntsig ntawd. Cov neeg Amelikas feem ntau tau tso tseg tsis saib cov xov xwm hauv TV. Saib cov txheeb cais hauv cov neeg saib xyuas poob txij li qhov tsis sib haum xeeb pib xyoo 2003 - feem ntau cov xov xwm hauv tebchaws tau poob txog 20% ntawm "cov neeg saib tsis tu ncua". Qhov no yog vim qhov hloov pauv mus tshaj tawm cov khoom teev ib teev dhau ib teev es tsis yog xov xwm txheej txheem thiab muaj cov xov xwm tshwj xeeb tau txais qhov tob ntxiv. Tam sim no tus neeg Amelikas nruab nrab tau txais nws cov xov xwm los ntawm Is Taws Nem thiab hmoov tsis zoo ob peb ntawm lawv siv blogs kom tau txais nws. Kuv kuj tau xa mus rau kev txiav txim siab tias "qhov nruab nrab nruab nrab" Asmeskas tseem xav kom txhua tus neeg hauv ntiaj teb ua raws li nws tus qauv kev ua neej thiab yuav txhawb kev cuam tshuam los pab nthuav tawm cov txheej txheem no. Nws tau dhau los ua qhov pom tseeb tias peb cov thev naus laus zis tau dhau los ntawm peb tib neeg. - Albert Einstein.
