English: The black triangles are the fraction of a large set of small supercooled liquid tin droplets that are still liquid, i.e., where the crystal state has not nucleated, as a function of time. The data is from Pound and La Mer (JACS 1952 http://pubs.acs.org/doi/abs/10.1021/ja01129a044). It is the data of experiment number 29, run 4 of the Fig. 3 in the original paper. I used datathief to extract the data from the figure. The red curve is a fit of a function of the Gompertz form to this data. If the fraction not frozen at time t is F(t), then the function is ln[F(t)] = – m[1-exp(kt)], and the best fit values are m = 1.18 and k = 0.019 /s.
