物理科学现代艺术图片欣赏 用形象的艺术语言表达深奥的物理科学 Caustic hree-dimensional caustics formed on a flat sea bottom by light passing through two consecutive wavy surfaces Caustics are places where things accumulate; in this case light is accumulating. We often think of focal points as places where light gathers after passing through a lens, but more generally, for "random"lenses, there are many more interesting patterns to examine Caustics are seen abundantly in the two-dimensional electron flow Transport series; there, we are looking at the flow as it moves along in two dimensions. Here, we are seeing the flow of light in three dimensions as it is interrupted by the sea bottom surface. This pattern is not possible for a true sea bottom, because the light has passed through seven consecutive surfaces, being refracted twice (Caustic I uses two such wavy surfaces to refract the light)

CausticⅣV Caustic iv displays folds, cusps, and swallowtails, which are typical caustic structures, her formed by looking through a ruled, transparent colored three-dimensional curved sheet Caustic lv displays folds, cusps, and swallowtails, which are typical caustic structures, here formed by looking through a ruled, transparent colored three-dimensional curved sheet. The heet itself is smooth(but not flat when we project it onto a plane by looking through it from a certain angle) we see accumulation regions where material builds up along the line of sight. One of the most common caustics is called a cusp Cusps result when a flat part of a sheet develops a fold somewhere along the sheet At a definite point, we can see two new edges or caustics where before none existed. Several of these can be seen in Caustic MV Caustic IV emphasizes the appearance of caustics in projections of higher dimensional objects onto lower dimension, a property also present in Torus and Torus V. a caustic is a region where the higher dimensional surface lies tangent to the projection, thus it's shadow"piles up"along a caustic Color hue and value in this image are determined in part by color subtraction of overlapping parts of the sheet

Interpenetrating Surfaces e peer through several interpenetrating approximately ellipically shaped surfaces. Electrons in molecules normally move a lot faster than the nuclei. This leads to the concept of effective potential energy surfaces that govern the motion of nuclei. These surfaces interpenetrate, and intersect in various ways. Their intersection actually causes a breakdown in the assumption that the motion of the nuclei can take place on the surfaces in the first place. The breakdown leads to interesting experimental consequences. Here we peer through several interpenetrating approximately ellipically shaped surfaces, transparent enough to see through into the next surface. Caustics develop as the viewing direction goes parallel to the surfaces. The breakdown of the so-called adiabatic" approximation is suggested by the broken nature and color chaos of the surfaces
