In order to ensure the security of answer keys and other instructor supplements, and to create a safe space for instructors to have open discussions about their teaching, we limit access of some parts of the Portal to verified educators. One of these is the idea of quantification: that physical quantities can be assigned specific numbers. There are two independent sources of this uncertainty. They allow us to challenge others (as well as ourselves) in our efforts to learn truths about the world. (b) Estimate the diameter of the Moon. Parameter Estimation In order to use such models we must somehow assign suitable values to the involved parameters; r0 and a in the model for exponential growth, ro, a and R in the model for logistic growth, and f(x)and k(x)in the model for heat conduction.
