Lub tswv yim tseem ceeb ntawm qhov tsis yog-Euclidean geometry yog qhov nws tau qhia meej txog kev sib raug zoo ntawm lej, kev tshawb fawb thiab kev soj ntsuam… uas dhau los ua txoj hauv kev rau Einstein's General Theory of Relativity.
Vim li cas Euclidean geometry tseem ceeb?
Txawm hais tias nws muaj keeb kwm yav dhau los, nws tseem yog ib qho tseem ceeb tshaj plaws hauv kev ua lej. Nws ua kom ib qho los suav qhov kev ncua deb lossis, qhov tseem ceeb dua, txhawm rau txheeb xyuas qhov kev ncua deb ntawm cov xwm txheej dav dav dua li theem pib geometry. Piv txwv li, nws tau raug generalized rau multidimensional vector spaces.
Vim li cas koj xav tias hyperbolic geometry tseem ceeb heev rau kev kawm?
Kev kawm ntawm hyperbolic geometry pab peb tshem tawm ntawm peb cov duab txhais lus los ntawm kev muab peb lub ntiaj teb uas cov duab hloov pauv tag nrho - tseem lub ntsiab lus tseeb ntawm cov lus siv nyob rau hauv txhua lub ntsiab lus tseem tsis hloov. hyperbolic geometry pab peb tsom mus rau qhov tseem ceeb ntawm cov lus.
Dab tsi yog qhov txawv ntawm Euclidean geometry thiab non-Euclidean geometry?
Qhov sib txawv tseem ceeb ntawm Euclidean geometry thiab ob qhov tsis yog Euclidean geometry yog qhov xwm txheej ntawm kab sib npaug: Hauv Euclidean geometry, muab ib qho taw tes thiab ib kab, muaj raws nraim ib kab dhau ntawm qhov taw tes uas nyob hauv tib lub dav hlau raws li kab uas tau muab thiab yeej tsis sib tshuam.
Kuv kawm dab tsi txog Euclidean thiab tsis yog-Euclidean geometry?
Thaum Euclidean geometry nrhiav kom nkag siab txog geometry ntawm tiaj tus, ob sab qhov chaw, tsis yog Euclidean geometry kev kawm nkhaus, es tsis yog tiaj tus, nto Txawm hais tias Euclidean geometry muaj txiaj ntsig zoo hauv ntau qhov chaw, qee zaum, tsis yog Euclidean geometry tej zaum yuav muaj txiaj ntsig zoo dua.

Puas yog alanine tseem ceeb lossis tsis tseem ceeb?
No tseem ceeb amino acids suav nrog: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, thiab tyrosine. Cov tshuaj amino acids feem ntau tsis tseem ceeb, tshwj tsis yog thaum muaj mob thiab kev ntxhov siab .
Vim li cas cov ntaub ntawv tseem ceeb tseem ceeb rau kev tswj hwm tebchaws Askiv?
Cov ntaub ntawv raug cai ntawm cov thawj coj hauv tebchaws Askiv ua haujlwm qhov tseem ceeb ntawm keeb kwm ntawm no lub sijhawm. Cov thawj coj hauv tebchaws Askiv ntseeg tias txhua qhov kev qhia, kev npaj, txoj cai, kev txiav txim siab, kev pom zoo, kev tshawb nrhiav yuav tsum tau sau kom meej.
Dab tsi yog qhov tseem ceeb thiab tsis tseem ceeb?
Qhov me dua p-tus nqi, qhov muaj zog pov thawj uas koj yuav tsum tsis lees paub qhov kev xav tsis tseeb. Ib qho p-tus nqi tsawg dua 0.05 (feem ntau ≤ 0.05) yog qhov tseem ceeb. … A p-tus nqi siab dua 0.05 (> 0.05) tsis yogqhov tseem ceeb thiab qhia cov pov thawj muaj zog rau qhov kev xav tsis zoo .
Vim li cas cov cim tseem ceeb tseem ceeb?
Background. Cov cim tseem ceeb yog qhov tseem ceeb cov ntsiab lus ntawm kev saib xyuas tus neeg laus lossis tus menyuam qhov kev vam meej thaum mus pw hauv tsev kho mob, vim lawv tso cai rau kev tshawb pom sai ntawm kev rov qab los qeeb lossis cov xwm txheej tsis zoo.
Vim li cas qhov tseem ceeb yog qhov tseem ceeb?
Nws yuav tsum muaj lub zog lub cev thiab lub siab lub ntsws. Qhov tseem ceeb yog qhov tseem ceeb uas tso cai rau koj mus txuas ntxiv thiab ua lub neej zoo. Hauv qhov tseem ceeb, qhov tseem ceeb txhais tau hais tias muaj zog, noj qab nyob zoo, thiab muaj txiaj ntsig zoo.
