用原子轨道的对称性破缺来解释化学元素周期表；在这里，我们介绍了液滴运动的周期表，也是基于对称破缺，但以最近的液滴光谱理论为指导。利用这一理论，发现了更高的液滴模态振型，并发明了润湿性谱仪。部分湿润的液体在支撑上的运动具有自然模态振型，运动按动能排列到元素周期表中，每个周期表都具有球帽滴体积和材料参数的特征。对于接触角约为60度的支撑物上的水，发现了元素周期表中预测的前35个元素。元素周期表通过对称破缺形成双参数家族树而相互关联。
Drawing parallels to the symmetry breaking of atomic orbitals used to explain the periodic table of chemical elements; here we introduce a periodic table of droplet motions, also based on symmetry breaking but guided by a recent droplet spectral theory. By this theory, higher droplet mode shapes are discovered and a wettability spectrometer is invented. Motions of a partially wetting liquid on a support have natural mode shapes, motions ordered by kinetic energy into the periodic table, each table characteristic of the spherical-cap drop volume and material parameters. For water on a support having a contact angle of about 60 degrees, the first 35 predicted elements of the periodic table are discovered. Periodic tables are related one to another through symmetry breaking into a two-parameter family tree.
