You know, you probably had this a long time ago in chemistry, where you had these two atoms, they're close together, and the electrons are moving around. That tiny force is sufficient to allow them to do that because it's added up so many times with these small structures.
Du havde sikkert noget om det her for længe siden i kemi, om, hvis to atomer er tæt på hinanden, og elektronerne bevæger sig rundt. Dén lille kraft er tilstrækkelig til at lade dem gøre dette, fordi det sker så mange gange med disse små strukturer.
