english: (Laughter) And that's terrifying, because the theoretical models that always work out in the answer key in the back of a teacher's edition, that's great, but it's scary to talk about sources of error when the theoretical does not match up with the practical.
non_english: (Smeh) I to je zastrašujuće. Jer teoretski modeli koji uvek rade u rešenjima na kraju knjige, oni su super, ali strašno je pričati o izvorima grešaka kada se teorija ne poklapa sa praktičnim.
