Rutherford nyob Manchester, 1907–1919. Ernest Rutherford nrhiav tau lub nucleus ntawm lub atom nyob rau hauv 1911.
Yog li ntawd, Ernest Rutherford ua li cas nws nrhiav tau?
Xyoo 1911, nws yog thawj tus pom tias cov atoms muaj lub ntsiab lus me me uas nyob ib puag ncig los ntawm qhov chaw khoob loj, thiab tau ncig los ntawm cov hluav taws xob me me, uas tau los ua lub npe hu ua Rutherford qauv (los yog planetary qauv) ntawm lub atom.
Ib sab saum toj no, Rutherford nrhiav tau lub nucleus li cas? Xyoo 1911, Rutherford , Marsden thiab Geiger nrhiav pom cov atomic tuab nucleus los ntawm kev foob pob ib daim ntawv kub nrog cov alpha hais tawm los ntawm radium. Rutherford thiab nws cov tub ntxhais kawm tom qab ntawd suav tus naj npawb ntawm cov hluav taws uas tsim los ntawm cov alpha hais txog ntawm zinc sulphate screen.
Ib yam li ntawd, Ernest Rutherford ua haujlwm nyob qhov twg?
Ernest Rutherford yug rau 30 Lub Yim Hli 1871 hauv Nelson , New Zealand , tus tub ua teb. Nyob rau hauv 1894, nws yeej ib tug scholarship rau Cambridge University thiab ua haujlwm raws li kev tshawb fawb tub ntxhais kawm nyob rau hauv Sir Joseph Thomson. Xyoo 1898, nws tau los ua tus xibfwb ntawm physics ntawm McGill University hauv Montreal , Canada.
Ernest Rutherford pab nyiaj rau atomic txoj kev xav li cas?
Ernest Rutherford paub txog nws txoj kev tshawb fawb pioneering ntawm radioactivity thiab atom . Nws pom tias muaj ob hom hluav taws xob, alpha thiab beta hais, los ntawm uranium. Nws pom tias tus atom Muaj feem ntau ntawm qhov chaw khoob, nrog rau nws cov huab hwm coj concentrated nyob rau hauv lub hauv paus zoo charged nucleus.

Qhov kev tshawb xav loj loj tau tshawb pom li cas?
Cosmic microwave keeb kwm yav dhau hluav taws xob Nyob rau hauv 1964, Arno Penzias thiab Robert Wilson serendipitously pom lub cosmic keeb kwm yav dhau hluav taws xob, ib tug omnidirectional teeb liab nyob rau hauv lub microwave band. Lawv qhov kev tshawb pom tau muab kev pom zoo ntawm qhov kev twv loj loj los ntawm Alpher, Herman thiab Gamow nyob ib puag ncig xyoo 1950
Leej twg tau txais txiaj ntsig los ntawm kev tshawb pom lub hauv paus rau kev tsim noob neej?
Thaum Gregor Mendel pib kawm txog kev xeeb tub hauv xyoo 1843, chromosomes tseem tsis tau pom nyob hauv lub tshuab tsom. Tsuas yog nrog cov koob tshuaj zoo dua thiab cov tswv yim zoo thaum lub sijhawm xyoo 1800s tuaj yeem ua rau cov kws tshawb fawb ntawm tes pib stains thiab saib xyuas cov txheej txheem subcellular, pom lawv tau ua dab tsi thaum lub sijhawm cell faib (mitosis thiab meiosis)
Vim li cas nws tseem ceeb uas peb txoj kev nkag siab txog kev tshawb fawb txog kev sib raug zoo txuas ntxiv mus?
Kev nthuav dav thiab kev loj hlob ntawm kev tshawb fawb txog kev sib raug zoo yog qhov tsim nyog vim nws pab txhawb koj txoj kev sib raug zoo thiab kev sib raug zoo nrog cov neeg hauv zej zog. Thaum koj nyob nrog cov neeg koj yuav tsum nkag siab lawv thiab social science pab koj ua li ntawd
Dab tsi yog chromosome txoj kev xav ntawm kev qub txeeg qub teg thiab nws cuam tshuam li cas rau Mendel qhov kev tshawb pom?
Piav Mendel cov lus xaus txog qhov zoo li cas dhau ntawm ib tiam dhau ib tiam. Lub chromosome txoj kev xav ntawm kev qub txeeg qub teg hais tias cov yam ntxwv qub txeeg qub teg yog tswj los ntawm cov noob nyob rau ntawm chromosomes ncaj ncees kis los ntawm gametes, tswj cov caj ces txuas ntxiv ntawm tiam mus rau ib tiam
Thaum twg John Dalton ua nws qhov kev tshawb pom?
1803 Ib yam li ntawd, John Dalton nrhiav tau atomic txoj kev xav li cas? Dalton's atomic txoj kev xav tau hais tias txhua yam teeb meem yog tsim los ntawm atoms , indivisible thiab indestructible tsev blocks. Thaum tag nrho atoms ntawm ib lub ntsiab yog zoo tib yam, txawv cov ntsiab lus muaj atoms ntawm txawv qhov loj thiab loj.
