In 1827, Askiv tus kws kho tsiaj Robert Brown pom tias paj ntoos noob raug tshem tawm hauv dej tau txav mus rau qhov tsis sib xws "swarming" motion.
Leej twg xub pom Brownian tsab ntawv tsa suab thiab thaum twg?
Nyob rau xyoo 1827, tus Scottish botanist Robert Brown tau saib los ntawm lub tshuab tsom iav ntawm paj ntoos nplej uas tau muab tshem tawm hauv dej, thiab pom qhov peb tam sim no hu ua Brownian Motion.
Thaum twg Einstein nrhiav pom Brownian tsab ntawv tsa suab?
Txoj kev xav no tau coj tus kws kho mob German Albert Einstein hauv 1905 los tsim nws txoj kev xav ntau ntawm Brownian motion.
keeb kwm ntawm Brownian tsab ntawv tsa suab yog dab tsi?
History: Brownian txoj lus tau tshawb pom los ntawm tus kws paub txog tsiaj txhu Robert Brown [2] xyoo 1827… Txawm li cas los xij, nws tsuas yog xyoo 1905 xwb uas Albert Einstein, siv tus qauv tsim nyog, tuaj yeem piav qhia txog Brownian tsab ntawv tsa suab. Nws tau pom tias yog tias lub zog kinetic ntawm cov kua dej yog qhov raug, cov molecules ntawm dej txav ntawm qhov sib txawv.
Einstein ua pov thawj Brownian tsab ntawv tsa suab li cas?
Nyob rau hauv qhov tseem ceeb, Einstein tau qhia tias cov lus tsa suab tuaj yeem kwv yees ncaj qha los ntawm tus qauv kinetic ntawm thermal equilibriumQhov tseem ceeb ntawm txoj kev xav nteg nyob rau hauv qhov tseeb tias nws tau lees paub qhov kev xav kinetic tus account. ntawm txoj cai thib ob ntawm thermodynamics raws li kev cai lij choj tseem ceeb.

Thaum twg hyperkalemic periodic paralysis nrhiav pom?
Hyperkalemic periodic paralysis (hyperPP) yog ib qho autosomal dominant leeg sodium channelopathy nrog ze li ua tiav penetrance [1]. Tyler et al. [2] thawj zaug piav qhia txog tus kab mob no hauv 1951hauv lawv txoj kev tshawb fawb ntawm 7 tiam neeg ntawm cov tib neeg uas muaj kev kho mob tsis tu ncua thaum tsis muaj hypokalemia .
Thaum twg pythagoras theorem nrhiav pom?
Pythagorean Theorem. Pythagorean theorem yog thawj zaug paub hauv Npanpiloo thaum ub thiab tim lyiv teb chaws ( pib txog 1900 BC). Kev sib raug zoo tau tshwm sim ntawm 4000 xyoo Babylonian ntsiav tshuaj tam sim no hu ua Plimpton 322 . Leej twg nrhiav tau Pythagorean theorem ua ntej?
Thaum twg da dej nrhiav pom?
1). Qee qhov kev ntsuas thawj zaug ntawm kev ntsuas da dej tau tsim los ntawm British explorer Sir James Clark Ross hauv 1840, los ntawm US Coast Survey pib xyoo 1845 nrog kev tshawb fawb ntawm Gulf Stream, thiab los ntawm US Navy, raws li kev taw qhia ntawm Matthew Fontaine Maury, pib xyoo 1849 .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
Qhov twg los saib kev tshawb nrhiav nrhiav pom?
Koj tuaj yeem saib Kev Tshawb Nrhiav Kev Tshawb Fawb ntawm ib qho ntawm cov kev pabcuam streaming hauv qab no: Philo, Hulu + Live TV, Sling TV, Vidgo, fuboTV, thiab YouTube TV. Cov kev pabcuam no muab tib tus ID channel uas koj pom ntawm cable thiab satellite TV .
