In the second semester of the second year of high school, physics tutoring became an auxiliary line, allowing the two parallel lines of Lin Songran and Jiang Yu, who were six years older, to meet for the first time. He was a top student at Harbin Institute of Technology and the "starlight" she looked up to. In the past six years, from the gentle explanations in the online class to the 40-minute view of Harbin's subway, from the light touch of the fingertips on the Dragon Boat Festival to the metaphor of phase change in the starry night on the grassland, she followed his trajectory and hid her secret love in the encrypted album of "Physics Notes".
The six-year-old gap is an invisible distance. His love affair and her dislocation and throbbing have repeatedly alienated these two lines. But the force of gravity is never absent. She has been tempered and grown in competitions and papers, and he has steadily moved forward on the road of scientific research. The "quality" given by time has made the mutual attraction stronger.
This is a youth pursuit that spans six years, a heartbeat code in a physical formula, and a story of parallel lines slowly approaching in the curvature of time. When the auxiliary line connects growth and waiting, when the conditions for phase change are quietly achieved, the once-out-of-reach point of convergence finally emerges with a clear outline in the light of self-achievement - it turns out that the best encounter is when I chase your light, and finally become the light of the same frequency as you.
Concept: "The law of conservation of momentum focuses on the selection of the system." "Some people exist not to be side by side with you, but to let you see the direction of the stars." "There is a concept called 'lattice matching' - for two materials to be combined, their crystal structures and atomic spacing need to match. If there is too much difference, stress will occur and eventually crack." "The most appropriate distance is to allow each other to become a better version of themselves." "We actively choose to become parallel lines and shine on our own tracks. This is a deeper resonance than intersection."
