english: A zeptowatt, if you put it in similar terms, is if you take just one grain of salt and then you imagine a tiny, tiny, little ball that is one thousandth of the mass of that one grain of salt and then you drop it one nanometer, which is a hundred times smaller than the wavelength of visible light, once per day.
non_english: Zeptovat je, jednostavno rečeno, ako uzmete jedno zrno soli a zatim zamislite sitnu, sitnu, malu loptu koja je jedan hiljaditi deo mase tog zrna soli a zatim ga ispustite jedan nanometar, što je sto puta manje od dužine talasa vidljive svetlosti, jednom dnevno.
