Week #1.2 January 4, 2012 Computer-based problem solving in Science and Engineering Pure math: about beautiful relationships, e.g. partial differential equations Applied math: pure math applied to a real-life problem, e.g. weather forecasting Computation: - obtain numerical results from the mathematical equations - problems: approximations, finite arithmetic, time, amount of data Why learn Computer Programming? why learn to play a musical instrument vs. playing a CD or ipod? why learn to cook vs. eating at a restaurant? why learn to sew vs. buying clothes? Why learn Fortran? Families of programming languages: Procedure oriented program is a hierarchy of subprograms examples: Fortran, Algol 60, PL/I, Basic, C, Pascal, Turing Object-oriented examples: C++, Java, Python Functional examples: Lisp, Scheme Logic examples: Prolog Not really learning a programming language or computer programming but learning algorithmic problem solving, which is language independent. Elementary Computer Organization google: "Little Man Computer" (read Wikipedia article, and "Von Neumann Architecture" look at others that come up) read: Chapter 2 of the textbook Let's design a computer… we need: - a place to store the data and the instructions that manipulate it …. the memory [storage room] - a place where the instructions are actually carried out
