1898 – Crookes’ Vis Generatrix

    

Model of Crookes’ "Vis Generatrix" made in 1898, built by his assistant, Gardiner. From: Proc. R. Soc. Lond. 63, 408.

The vertical scale represents the atomic weight of the elements from H = 1 to Ur = 239. Missing elements are represented with a white circle. Similar elements appear underneath each other. With this model, Crookes was trying to visualize the hypothetical relationship between various elements in three dimensions.
