"This book..."
Baili Qingfeng flipped through these books.
Force, common types of force, the composition of forces, the decomposition of forces...
"This isn't related to electromagnetism, but I can't neglect any subject... Otherwise, it'll inevitably affect my final score. Even if this isn't the knowledge I want, I still have to endure it and finish reading it."
Baili Qingfeng pursed his lips and continued flipping through the books.
Interaction of forces, friction, static friction, coefficient of friction, resultant force, centrifugal force, vibration and resonance...
"This is a little interesting."
Baili Qingfeng had been reading it like chewing tasteless wax when he suddenly stopped.
In the early nineteenth century, an army marching in perfect step had crossed a stone bridge. Using the principle of resonance, they had actually stomped a great bridge into collapse.
"Amplitude, period, frequency, natural frequency... resonance..."
Baili Qingfeng looked at the description in the book.
A countrywoman had played a flute, yet it had caused the caterpillars on the fruit trees to die one after another. This was because the flute's sound had transmitted vibrations through the air to the caterpillars, forcing them into vibration. Since their frequencies had been similar, resonance had caused the caterpillars' internal organs to rupture, resulting in their deaths.
"If this could be studied, perhaps I could create a martial art or secret technique that uses vibrational waves to trigger resonance in another person's internal organs and tear apart their five viscera and six bowels."
Baili Qingfeng himself had a solid foundation in physics. To create a secret technique based on resonance, he would also need to understand vibrational waves.
There were quite a few types of vibrational waves. Setting aside the basics of transverse and longitudinal waves, he also had to understand the relationships between a wave's period, wavelength, and speed,
