To bolo dobreeeee! Ucivo fyziky v praxi. Pre tych, ktori to nerozumeli, preklad v dvoch jazykoch...
Isaac Newton would say: The ball and the feather fall, because there is force pulling them down. Gravity.
But Einstein imagined the scene very differently... the happiest thoughts of his life was this:
The reason why the boulding ball and the feather falling together is, because they are not falling. They standing still. There is no force acting on them at all.
The reason, if you couldn't see the background, there will be no way of knowing, that the ball and the feathers have been accelerated toward the Earth. So he concleted, they weren't.
Isaac Newton by povedal, že guľa a pierko padajú, lebo na nich pôsobí sila. Gravitácia.
Ale Einstein si predstavoval scenár inak. Najviac v živote ho nadchla úvaha, že:
Dôvodom, prečo guľa a pierko padajú naraz je, že oni nepadajú. Stoja pevne. Nepôsobí na nich žiadna sila.
Vysvetlenie je, keby sme nevideli pozadie, nebola by možnosť vedieť, že guľa a perie vykonali rovnomerné zrýchlenie smerom k Zemi. Tak dospel k záveru, že sa tak ani nestalo.
