So he sat down -- and I imagine he had nothing more than a simple piece of paper and a pencil -- and he tried to write down, and did write down, the simplest function that he could think of which had the boundary conditions that the wave function vanish when things touch and is smooth in between.
I tako je sjeo za stol -- mislim kako i nije imao ništa više od običnog papira i olovke -- pokušao zapisati, i zapisao, najjednostavniju funkciju koje se mogao sjetiti a koja je imala takve uvjete graničnosti zbog kojih bi valna funkcija nestala kada se stvari dodirnu i koja nema titraja između.
