"Yes, but," Eino engaged in conversation with the fiery Ravenclaw girl and the Slytherin prefect, "You can't fix something without listing all of its faults first." He adjusted his seat so that he could face both of them without having to twist his torso and injure himself. "That's like trying to heal someone without a proper diagnoses."

Yeah, that's right. There's a real Ravenclaw in the building now.

"In addition to that, he," Eino gesture to the Slytherin prefect, "did, although indirectly, list some ways in which the formula could be improved." He couldn't remember everything the boy had said but hopefully he had correctly understood the few parts he managed to hear. "He mentioned that one of its faults is the fact that it uses fractions, so we should find a way to use whole numbers instead. Another problem he pointed out was how the equation treats these extraterrestrial beings as humans, and won't consider any other life forms. A way to fix that might be to start by studying the planet itself, its characteristics, etc. I heard just a moment ago that a different planet is significantly hotter than Earth, so a human like us could not inhabit in it. Of course this equation would not work in that unless we took the excessive heat it is exposed to into consideration. It would be very difficult, but it is a way of improving it..."
