Figure 2. Stress-strain curve of iron obtained using the Johnson I potential, showing the phase transition from the bcc (\alpha-phase) to the fcc (\gamma-phase) structures under tensile stress and the reverse transition under compressive stress. MC simulations at 70 K (closed circles) and static c... More about this image found in Stress-strain curve of iron obtained using the Johnson I potential, showing...

Figure 1. (left) Schematics of gravitational lensing reproduced from Sanitt and schematics of gravitational lensing reproduced from Gott and Gunn. In this diagrammatic world, there is only one reading—for any trained astronomer, the paths of the light rays show a gravitational lens. Originally p...

Figure 2. (left) Spectroscopic data showing the emission and absorption lines of 0957+561 A and B. To the trained expert’s eye, the similarity in these peaks and valleys is shocking. Originally published in D. Walsh, R. F. Carswell, R. J. Weymann, “0957 + 561 A, B: Twin Quasistellar Objects or G...

Figure 3. (left) Image of Abell 370. The suspicious arc can be clearly seen along with several galaxies. (right) The model produced by Soucail et al. The arc gets meaning through the model—no longer a mystery, it is now a lensed image. Originally published in G. Soucail, Y. Mellier, B. Fort, G...
