This course introduces the broader discipline of computer science to people having basic familiarity with Java programming. It covers the second half of our book Computer Science: An Interdisciplinary Approach (the first half is covered in our Coursera course Computer Science: Programming with a Purpose, to be released in the fall of 2018). Our intent is to demystify computation and to build awareness about the substantial intellectual underpinnings and rich history of the field of computer science.

This course introduces the broader discipline of computer science to people having basic familiarity with Java programming. It covers the second half of our book Computer Science: An Interdisciplinary Approach (the first half is covered in our Coursera course Computer Science: Programming with a Purpose, to be released in the fall of 2018). Our intent is to demystify computation and to build awareness about the substantial intellectual underpinnings and rich history of the field of computer science.

First, we introduce classic algorithms along with scientific techniques for evaluating performance, in the context of modern applications. Next, we introduce classic theoretical models that allow us to address fundamental questions about computation, such as computability, universality, and intractability. We conclude with machine architecture (including machine-language programming and its relationship to coding in Java) and logic design (including a full CPU design built from the ground up).

The course emphasizes the relationships between applications programming, the theory of computation, real computers, and the field's history and evolution, including the nature of the contributions of Boole, Shannon, Turing, von Neumann, and others.

All the features of this course are available for free. People who are interested in digging deeper into the content may wish to obtain the textbook Computer Science: An Interdisciplinary Approach (upon which the course is based) or to visit the website introcs.cs.princeton.edu for a wealth of additional material.

This course does not offer a certificate upon completion.

Reviews summary

Deep dive into cs fundamentals

According to learners, this is an outstanding course that provides a deep dive into fundamental computer science concepts. Students praise the coverage of algorithms, the limits of computation, and how computers actually work at a deep level. The course features excellent instructors and top-notch materials, with assignments described as challenging but rewarding. However, the course is also noted as challenging and having a fast pace, potentially feeling abstract in sections like machine architecture. It requires prerequisite knowledge in programming and logic, and the recommended textbook is seen as essential for full understanding.
Strong in theory, sometimes lacks practical ties.
"...the section on machine architecture felt very abstract and hard to follow without more practical examples or labs."
"The theory parts are interesting, but the section on machine architecture felt very abstract and hard to follow..."
"...the concepts were explained in a very theoretical way without enough practical application."
Companion textbook is highly useful.
"...though the recommended textbook is essential for fully grasping everything."
"The textbook is necessary, but adds cost."
Excellent lectures and course materials provided.
"The instructors are excellent, and the materials are top-notch, though the recommended textbook is essential..."
"Excellent lectures explaining complex topics clearly."
"The lectures are dense but full of valuable insights."
Covers core CS principles deeply.
"An absolutely outstanding course. Covers fundamental algorithms, the limits of computation, and how computers actually work at a deep level."
"This course is exactly what I was looking for - a deep dive into why computers work the way they do."
"Covers essential CS concepts often skipped in programming-focused tracks."
Assumes prior programming/logic knowledge.
"Assumes a stronger math/logic background than I had."
"It definitely requires the Programming with a Purpose prerequisite or similar background."
"Not for the faint of heart or those without a strong CS background already."
The course is demanding and fast-paced.
"The pace can be quite fast, especially in the later weeks covering circuits and CPU design. Some parts felt a bit rushed."
"Found this course very difficult. Assumes a stronger math/logic background than I had. The pace was relentless..."
"It's a challenging course, definitely not easy. Requires dedication and time."
