Tom's soul memories had been sealed by the Seed of the Mind. This included memories of all kinds of spells, leaving him blank before enrollment.
The spells he had mastered, aside from the simple ones he had "recalled" through the Book of Guidance's quest rewards, had all been learned recently through self-study, such as the Disarming Charm and Incarcerous.
Those offensive spells were far more difficult than the everyday spells Hermione used, and Tom had been exposed to magic for less time. Reaching this level could only mean that he truly was a genius.
After the two young wizards had completed four sets of comparative experiments, Murphy used magic to temporarily construct a darkroom nearby. He developed the dozens of photos they had taken, then used magic to speed up the printing process and produced dozens of oversized photographs.
He numbered every photograph, stepped out of the darkroom, and handed twenty oversized photos each to Tom and Hermione. Then he gave each of them a stack of forms. "Do you see the numbers on the Magic Power Testers?"
"Copy the readings from each Magic Power Tester into the corresponding boxes according to their numbers. Each form corresponds to one photograph, and the form number must match the photograph number."
"Professor, what is this for?" Hermione asked.
"Do you remember what I said about quantification?"
"We designed an experiment and controlled the key variables. As for the results, we need to quantify them as much as possible."
"For today's experiment, we are using Magic Power Testers to monitor magical power. We will record the magical power values with and without wands, then analyze and compare them, drawing conclusions from the data."
"That is why I said you should study more mathematics: to better analyze data."
"Of course, today's experiment is very
