12.1 Two of them use direct measures. In Example 6.2, Feynman directly studies the effect of cold on the resilience of the O-ring. In Example 6.3, Mendel studies inheritance by direct studies of characteristics. The other examples use indirect measures. 6.1: Harvey studied the motion of the blood, for instance by looking at the color of the heart when obstructing the flow of blood to or from it. 6.4: Hershey and Chase drew conclusions about the genetic material of viruses by seeing where a radioactively labeled material ended up after infection. 6.5: Millikan studied the “atomic” nature of the electric charge by making charged drops hover in an electric field. 6.6: Chartier studied the impact of overleaning on the emissions of hydrocarbons by looking at the reactivity and composition of the fuel–air mixture near the injector. 6.7: Andersson studied the evolution of male ornaments by sexual selection through counting the number of active nests in the territories of tail-treated widowbirds.
