Quan Hongchan Reveals Her Secret to Minimizing Splash
Straightforward Explanations Make the Best Science Popularization

When Olympic diving champion Quan Hongchan visited Guangdong Experimental High School, her classmates asked how she minimized splashes upon entering the water. Instead of reciting obscure mnemonics, she demonstrated the technique on the spot: raising both arms, interlocking her hands with the backs pressed together, flattening her palms and pressing them against her ears. She explained, “Grip the back of one hand firmly with the other, keep your arms tight to your ears as you extend them upward, and apply sufficient force.” With a simple physical demonstration and plain everyday language, she laid bare the core entry technique known within diving circles as “interlocked flat palms” for ordinary audiences.

The public usually only fixates on how large or small the splash is, yet few understand the fine points of force application as athletes dive into water. The technical expertise accumulated by elite athletes has long been passed down orally between coaches and trainees within the sport, inaccessible to casual enthusiasts. Rather than treating the key movements as closely guarded trade secrets, Quan Hongchan broke down the underlying mechanics through the simplest demonstration: upon water entry, flatten and interlock both palms to form a flat surface, hold arms flush against the ears, and rely on the broad flat plane striking the water instead of piercing it like a wedge to suppress splashes. This aligns with a fundamental principle in fluid mechanics: a cuboid-shaped entry creates far less splash than a wedge-shaped entry.

This incident illustrates a universal truth: the most critical underlying principles across all industries are often simple and straightforward. Many fields tend to hoard core technical ideas and refuse to explain them to outsiders. In competitive sports, frontline athletes openly share the tricks behind their craft; in scientific research, dedicated scholars lay out complete theoretical frameworks clearly. Though their fields differ, both share the same logic of bridging information gaps. When practitioners with hands-on expertise dare to explain core principles in accessible terms, the general public can look past clickbait narratives such as “genius showdowns” or “underdog triumph stories” and perceive matters as they truly are.

Competitive sports refine technical precision through relentless training, while fundamental scientific research uncovers underlying mechanisms based on objective natural laws. Though these two pursuits have distinct goals, both ought to uphold a commitment to truth and realism. Only by openly unpacking core logic and engaging in rational exchange can we steadily broaden public understanding.

A simple rule applies to all walks of life: as long as clear-minded practitioners who uphold objective standards exist and have a platform to voice their views freely, opportunistic, impetuous trends disconnected from core pursuits will not spiral out of control. Scientific exploration follows this same logic. Brain science still holds countless unsolved fundamental mysteries. Academic progress requires both respect for the cumulative achievements of predecessors and space for independent critical thought. Only by pursuing in-depth original research grounded in objective laws and consistently amplifying rational, rigorous academic discourse can we sustain a calm, truth-seeking ecosystem for fundamental research.
