Outside the gates of Hogwarts, in the core academic lecture hall of the research area.

A few minutes ago, the keynote speaker, Ms. Minerva McGonagall, had just concluded her lecture on the cutting-edge theories of Transfiguration magic.

Now was the Q&A session after the lecture, and she was patiently answering questions from the audience.

Professor McGonagall, dressed in a simple black robe and wearing a pointed wizard's hat, looked like a witch straight out of a medieval oil painting. At first glance, it seemed as if she were teaching in a large Transfiguration classroom, but the bizarre questions she was answering, and the middle-aged and elderly audience members sitting below in long-sleeved shirts, completely ruined the magical atmosphere.

With the podium as the dividing line, the warm light and mahogany seemed to divide the lecture hall into two distinct worlds.

"...Therefore, when an object looks like an apple, feels like an apple, smells like an apple, and tastes like an apple—but its core is not an apple, it still has a way to be falsified, is that correct?"

Alchipovna glanced at her notebook, waiting for Professor McGonagall's answer.

Professor Quirinus Quirrell happened to be sitting next to her, but judging from the awkward expression on Quirrell's face, the Muggle Studies professor hadn't been able to answer her confusion, so she had to stand up and continue to question Professor McGonagall.

"That's right, Reverse Transfiguration can restore objects that have been transfigured together to their original state."

Professor McGonagall said softly, a slight impatience in her heart, but not showing it on her face.

"In addition, certain spells can also help wizards distinguish transfigured objects, such as the Copying Charm, the Summoning Charm—"

"Oh, I'm sorry, I'm not talking about magical ways—"

Alchipovna said quickly, with only five minutes for each person, she had to be efficient.

"If we try physical separation and chemical reactions on the transfigured object, is it possible for these actions to undo the magical effect? You said during your lecture that Gamp's Law of Elemental Transfiguration has five exceptions, when wizards try to eat them or try to utilize their chemical properties, the magic will be undone in advance—this is undoubtedly very crucial."

"Physical? Chemical reactions? I'm sorry... what is that?" Professor McGonagall asked politely.

"For example, cutting, bending... this counts as a physical level—the molecular structure doesn't change; while if it's burning, digestion... these will destroy the molecular structure and generate new substances, we classify these as chemical reactions."

Alchipovna rolled her eyes and explained quickly and expertly.

Compared to Professor McGonagall, she was already accustomed to the differences in common sense between the two worlds.

Especially recently, she had several more "wizard apprentices" every night, and Alchipovna knew how to quickly conduct basic science popularization—according to Quirrell, she could even apply to be a Muggle Studies teacher.

"In short," Alchipovna continued, "in my understanding, Transfiguration is a magic that studies the 'replacement' of an object's molecular structure to change its appearance and form, and it is applicable to the vast majority of objects."

Her eyes gradually began to shine, as if flames were burning inside.

"Obviously, from the perspective of spell principles, Transfiguration has more scientific attributes than other magic and can be applied to a wider range—I strongly agree with the introduction at the beginning of your speech: Considering the precision and complexity of Transfiguration, learning Transfiguration requires a systematic, clearly guided training mechanism, strict scientific thinking, and magical literacy."

"Ms. Alchipovna, I didn't say scientific thinking..."

McGonagall pursed her lips, glanced at the Muggle scholar, and said helplessly.

"Moreover, I said at the beginning that this theory has not yet been proven, it is just some of my personal understanding. In the mainstream magical world, wizards still use Gamp's Law of Elemental Transfiguration as the basic guide for learning Transfiguration. This statement is just a new conjecture about the essence of Transfiguration, but whether it is superior to the original theory is still a..."

"Entities should not be multiplied unnecessarily. This is a famous principle put forward by you British."

Alchipovna said softly, looking earnestly at Professor McGonagall, and continued.

"If we find two or more principles that can explain the observed facts, then we should use the simpler or falsifiable one until more evidence and inferences are discovered. The simplest explanation for a phenomenon is often more correct than a more complex explanation—obviously, your inference is far more competitive than 'Gamp's Law of Elemental Transfiguration'."

"So..."

Professor McGonagall raised her eyebrows in surprise, and asked thoughtfully.

"Do you fully understand what I just said? About the cutting-edge theory of Transfiguration, this should be the first time everyone has systematically understood Transfiguration, right—I think perhaps you don't understand that magic and science are not completely equivalent."

"It's not complicated, is it—you explained it very easily, Professor."

Alchipovna tapped her notebook and said with a smile.

"When a wizard casts Transfiguration, there are three important key points—"

Alchipovna held up her fingers, summarizing unhurriedly.

"Steady, decisive movements of the wand; clear and accurate imagination of the casting result; understanding and cognition of the object being spelled—especially when first learning Transfiguration, practicing standard wand movements and concentrating attention become extremely important, avoiding unnecessary shaking or rotation of the wand, otherwise Transfiguration will not succeed, and there will be repercussions and unexpected situations."

"In other words, it is to establish a stable and continuous energy output, thereby constructing a clear virtual conceptual framework, and finding a way to cover the target—this aspect is actually very similar to our industrial processes."

"As for what you said later, improper operation may cause the target object to only achieve half-transfiguration, or even be permanently fixed in a certain state, unable to recover, resulting in permanent complete transfiguration or permanent partial transfiguration..."

Alchipovna put her finger on her lips, a thoughtful look flashing in her eyes, and said uncertainly.

"I suspect that this may not be the effect of Transfiguration. Because if it is the magical effect of Transfiguration, then even in the case of failure, they should also meet the basic definition—whether it is Gamp's Law of Elemental Transfiguration, or the new theory you proposed later, making things change is not their core commonality, their common law lies in continuous effectiveness."

"...Well, your guess is not without reason."

Professor McGonagall pondered for a moment, her gaze paused on a white-haired old wizard in the corner of the stage, then lingered on the two little witches next to the old wizard, sighed with mixed feelings, and said softly.

"In fact, in the magical world, someone does define it this way. She believes that some failed permanent Transfiguration may be the result of unconscious rudimentary Alchemy, but this is another subject to be studied..."

"Then, if there are no other questions, we can proceed to the next step of today's content—"

Professor McGonagall lowered her head, looked at the schedule placed next to the podium, took a deep breath.

"Everyone has a general understanding of the two theories of Transfiguration, so if Hogwarts is preparing to promote educational reform in Transfiguration, based on these theories, what aspects do you think should be supplemented in the Transfiguration classroom—mainly from the educational cognition of the non-magical world, and what you think the wizarding world may lack after listening to the lecture..."
