Welcome to CS1101 & SOC

Bad news…CS1101 is hard,CS1102 is harder… need I say more?

Good news… It may be hard, but it is do-able,And we have many live examples…Aaron is the best instructor

Multiple winners of Best Teacher Awards

CS1101 outcomes (2)…

Using Java as a vehicle Writing Java program Famaliarity with Java syntax, features, etc Data types (simple, structured, libraries) Statements (assignment, if, case, while, repeat) OO features: class, objects, inheritance, etc

Appreciate relevance of mathematics Discrete math, discrete modelling, graph theory

Develop good programming styles and habits

The Message….

Programming is Difficult,

It can be acquired,

It is Challenging,

YET STIMULATING

Some Underlying Principles

Recurring principles (themes) in CS & IT. They pop-up in multiple places…

1. Multiple Levels of Abstraction from very high level to very low level

2. Divide and Conquer also called “Decomposition”

3. One data, multiple views Different “interfaces”

4. Defining set of primitives (building blocks) Or basic-operations, mini langugages

5. Power of Iteration doing something multiple times

Modern view of Computing…

Theory, Abstraction, Design and Social Context Three distinct paradigms

Social Context of Computing

Theory

Abstraction

Design

Social Context

Theory ParadigmTend to take mathematician’s viewpointConcerned with formal definitions, axioms,

and theoremsProofs as underlying media for exploring

ideas and thoughts about computation

Modern view of Computing (2)

Abstraction Paradigm Scientific point of view Rooted in the sciences (physics, chemistry, biology) Concerned with formation of hypotheses, construction of

models Making predictions, running experiments, and testing results Perceiving patterns in midst of details and the formal

representation of these patterns

Design Paradigm Rooted in Engineering Concerned with system feasibility, costs, efficiency, and

alternatives Accessing requirements, formulating specifications
