Chen Ze from the Department of Physics and Chen Xintong from the School of Liberal Arts met in September when the parasol trees were rustling because of partial differential equations. The Greek letters he solved collided with the crisp sound of her pen rolling down, and the scratch paper became a hidden magpie bridge between quantum mechanics and poetry. When the collision on the basketball court caused the ginkgo bookmark to reveal the "electronic cloud love letter", the moonlight in the laboratory building witnessed the night when they used wave functions to analyze "The Wasteland". The pressure to maintain research has caused the two coordinate systems to become misaligned - he is trapped in the Pauli Exclusion Principle in the German laboratory, and she is drifting away guarding the "Feynman Lectures on Physics" in the old bookstore in her old city.
Seven years later, during the live broadcast of the Nobel Prize ceremony, he saw the glimmer of pearl earrings in the audience. When she caught up with her at the Paris Literary Salon, she was using her Copenhagen interpretation to dismantle the quantum entanglement of "Jin Se". The yellowed draft paper was re-opened on the bank of the Seine, and the unfinished double-slit interference pattern finally penetrated time and space - the ginkgo bookmark in his suit pocket and the Dirac equation in her poetry collection combined to form a Möbius strip spanning light years. On the day she returned to school at the age of eighty, she put the jasmine sachet from her youth into the particle collider model in a wheelchair. The goose-yellow hair rope in his white hair was still tied with the Schrödinger equation that could not be solved that year.
