But knowing the molecule structures at 50C and 75C tells you very little about the freezing point. Different example: If you measure the number of cases of a given virus, it will either spread across the entire globe (R0 > 1, eg. COVID-19) or fail to spread widely (R0 < 1, eg. Ebola). Even though it's not completely binary, it's emergent behaviour because it looks binary. But if you were to measure R0 directly, you'd see a gradual increase, and could predict future variants/vaccine efficiencies/etc much more easily. "Emergent" refers to eg. sigmoids, while "gradual" refers to eg. linear or logarithmic functions.
