Xue has long been fascinated by how electrons move within the confined space of atoms and molecules. In quantum mechanics, their presence is never fixed; they exist as electron clouds: ephemeral, shifting, and unpredictable.

Using ignited incense as a light source, the artist guides its glowing tip through improvised gestures that evoke imagined electron orbitals. Each act of burning, driven by electrons seeking more stable energy states, embodies both destruction and creation, a moment of light sedimenting onto photographic paper in the darkroom. Behind every glimmer lies a cascade of electron rearrangements and transitions.

The resulting luminograms are not scientific diagrams, but residues of movement—layered, fluid, and erratic, like the electrons themselves. The trajectories here are the memory of the electrons vertically approaching the blue.

薛林长久以来一直着迷于电子如何在原子和分子的狭小空间中运动。在量子力学中，电子没有固定的位置。它们以电子云的形式存在。它们短暂、流动，也难以预测。

以燃烧的线香作为光源, 他引导香头的微光，进行即兴的移动。这些动作回应了他想象中的电子轨道。燃烧是由电子向更稳定的能量状态转变所驱动的。它同时包含破坏与生成。光也因此在暗房中沉积于感光相纸之上。每一次闪烁的背后，都发生着大量电子的重新排列与能级跃迁。

最终形成的光绘作品并不是科学图解。它们是运动留下的痕迹。它们层层叠叠、流动而不规则。如同电子本身。在这里，轨迹成为电子的记忆。它们并非真实的电子轨迹，而是不可直接看见之物留下的诗性痕迹。这些轨迹垂直地接近一种蔚蓝。
