What is this course?

• Computer programming
• Write software using Java
• Understand Computer Science as a

discipline.

2

• The word "computer" was first recorded as being

used in 1613 and originally was used to describe a human who performed calculations or computations.

Computer

3

1943-1946, first electric programmable computer - ENIAC

• 1,800 square feet
• 18,000 vacuum

tubes

• weighing almost 50

tons

4

23 June 1912 – 7 June 1954

Alan Turing

• 1936, “Turing machine”
• 1. The machine was a device that printed symbols on paper tape in a

manner that emulated a person following a series of logical instructions.

• 2. This idea builds the foundation for theories about computing and computers

Modern computer

• World War II, a number of techniques for breaking

German ciphers

• 1950, “Turing test”

machine's ability to exhibit intelligent behavior equivalent to,

• r indistinguishable from, that of a human.

5

Computer programming: “Teaching” the computer to perform a set of tasks Code: The content you wrote in a programming language.

Computer Language: Used to Describe data and actions

Computer science

• Computer Science:
• "Computer science is the study of computers and algorithmic

processes, including their principles, their hardware and software designs, their applications, and their impact on society." - CSTA, 2011

• The study and the science of the theoretical foundations of

information and computation and their implementation and application in computer systems. (Wikipedia)

Information Complexity Computability

CS != programming

programming : CS ::

bicycling : PLU machining : engineering grammar : literature equations : mathematics

CS Research

• CS is a crucial tool for researchers of all kinds

(across disciplines)

• Simulation: galaxy evolution, protein modeling, weather

forecasting

• Medicine: simulation of surgery, modeling human

systems, info. management.

• Engineering: simulation of structures, traffic simulations,

CAD, CAM, etc.

• Biology: Genetics, protein folding, computational

biology, bioinformatics,

1 5

CS Research

• CS has it’s own big questions
• What is computable? What is not computable?
• How can we make better software?
• AI, self-driving cars
• Robotics
• Art and computer graphics
• Can computers learn/think?
• ...

How to succeed?

• GPA 4.0?
• IQ > 160?
• Knowledge about computer?
• Programming experience?

• Interest
• Hard working
• Good attitude

Academic Honesty

We encourage:

• use of JavaDocs, Java Tutorials
• talking with each other when solving problems
• HOWEVER, unless collaboration is explicitly allowed -
• All submitted work (for a grade) must be your own work

Thus…

• Acknowledge every source used explicitly
• Understand the work you hand in
• DO NOT share printed or electronic copies
• DO NOT view or copy solutions/program code from other students (even

from other semesters!)

Before you leave today…

• apply for access

https://www.cs.plu.edu/hub

• complete the student information survey

For next time…

• buy the book
• read chapter one
• look over lab 0
• check out the web pages and Sakai site
