Lub Laboratory tau tsim nyob rau hauv 1943 raws li qhov chaw Y ntawm Manhattan Project rau ib lub hom phiaj: tsim thiab tsim ib atomic foob pob . Nws tsuas siv 27 lub hlis xwb. Lub Xya Hli 16, 1945, lub ntiaj teb thawj zaug atomic foob pob tau detonated 200 mais sab qab teb ntawm Los Alamos ntawm Trinity Site ntawm Alamogordo Kev foob pob Ntau yam.

Yog li ntawd, leej twg tsim thawj lub foob pob tawg?

Robert Oppenheimer

Ib yam li ntawd, thaum twg Manhattan Project pib? Xyoo 1939-1946

Tsuas yog li ntawd, Manhattan Project tau ntev npaum li cas?

Cov Manhattan Project pib me ntsis hauv xyoo 1939, tab sis loj hlob mus ua haujlwm ntau dua 130,000 tus neeg thiab raug nqi ze li US $ 2 billion (kwv yees li $ 23 nphom hauv 2018 las).

Manhattan Project.

Manhattan District
Qhov kev sim Trinity ntawm Manhattan Project yog thawj qhov tawg ntawm riam phom nuclear.
Active	1942–1946
Disbanded	15 aug 1947

Cov foob pob atomic tau ua li cas?

Atomic foob pob yog ua nce ntawm ib qho fissile keeb, xws li uranium, uas yog enriched nyob rau hauv lub isotope uas muaj peev xwm txhawb nqa ib tug fission nuclear saw cov tshuaj tiv thaiv. Thaum ib tug dawb neutron hits lub nucleus ntawm ib tug fissile atom zoo li uranium-235 (²³⁵U), uranium faib ua ob lub me me hu ua fission fragments, ntxiv rau ntau cov neutrons.

Cinder cone volcanoes yog me me, feem ntau tsuas yog hais txog 300 feet (91 meters) siab thiab tsis nce siab tshaj 1,200 feet (366 meters). Lawv tuaj yeem tsim nyob rau lub sijhawm luv luv ntawm ob peb lub hlis lossis xyoo

Nws siv sijhawm ntev npaum li cas rau nebula los ua tus protostar?

Cov cores yog denser tshaj huab cua sab nrauv, yog li lawv tawg ua ntej. Raws li cov cores vau lawv tawg mus rau hauv clumps nyob ib ncig ntawm 0.1 parsecs loj thiab 10 mus rau 50 hnub ci huab hwm coj hauv huab hwm coj. Cov clumps no ces tsim rau hauv protostars thiab tag nrho cov txheej txheem yuav siv li 10 lab xyoo
