english: The way you measure nanotechnology is in nanometers, and one nanometer is a billionth of a meter, and to put some scale to that, if you had a nanoparticle that was one nanometer thick, and you put it side by side, and you had 50,000 of them, you'd be the width of a human hair.
non_english: Mierka nanotechnológie sú nanometre, Jeden nanometer je miliardtina metra. Na porovnanie, jedna nanočastica o hrúbke 1 nm vedľa druhej, dokopy 50,000 nanočastíc by mali šírku ľudského vlasu.
