The chairs of the Federal Reserve System are often regarded as having more direct influence over the current economy than presidents. Repeat the exercise in Problem 5 substituting Federal Reserve chairs for presidents, starting with P. Volcker in 1979. On the basis of these two tables, which Fed chair do you regard as most successful (or as the luckiest) economically? Presidents of the United States William Clinton 1993-2001 George W. Bush 2001-2009 Barack Obama 2009-2016 Donald Trump 2016-2019 Federal Reserve...

Materials engineers often create new alloys in an effort to improve the properties of an existing material. ZnO-based semiconductors show promise in applications like light-emitting diodes, but their performance can be enhanced by the addition of small amounts of cadmium. One material that has been studied can be represented by the formula Zn 0.803 Cd 0.197 O. (These materials are solid solutions, and so they can have variable compositions. The non-integer coefficients do not imply fractional atoms.) Express the composition...

Often in engineering calculations we want to be able to work with material properties that vary with extensive properties like Temperature and Pressure. For example the specific heat of air varies appreciably with temperature. As in that link, these property variations are determined from experiments and tabulated for specific temperature intervals. The table represents a numerical function, i.e. it gives cp(T). What I'm looking for is a module to code this in python. Is there a scipy or numpy function...
