Dear PHF Colleagues: I believe this thread will be of interest to junior PHF members who are uncertain of the answers. I ask the PHF elites; Please hold off "telling the answer" until we have 8 or so junior-level replies. Thanks. =============== To my thinking, a construct is a proven and tested approach, a specified, plan for some successful outcome. An example: Double-Entry Book Keeping: As business persons account for cash, to get it right, they use the construct, double-entry accounting. Counting money is what it is but in a "construct" way. Vectors: Are vectors a mathematical construct? Is the derivative a construct. What are your understanding of what is a "construct." Force: Clearly, force is a construct. Should teaching physics go.. "No, Jonny, there is no such thing as a force. Force is a construct invented only as a helpful way of thinking about physics."
