In 1946, "Fortune" magazine illustrated a cover story on "Fundamental Science" with a representation of the thermodynamic surface that Maxwell had built based on Gibbs's proposal. Rukeyser called this surface a "statue of water" and the magazine saw in it "the abstract creation of a great American scientist that lends itself to the symbolism of contemporary art forms." The artwork by Arthur Lidov also included Gibbs's mathematical expression of the phase rule for heterogeneous mixtures, as well as a radar screen, an oscilloscope waveform, Newton's apple, and a small rendition of a three-dimensional phase diagram.
