The Universe is computable. Information is its fundamental property, along with space and time. Computer science is a young field, but we didn't invent computing, we've discovered it. Codexpanse explores the computing nature of reality, ideas of programming and math, and our role in this exciting world.

    David Kopec: Classic Computer Science Problems in Java

    A conversation with David Kopec, Assistant Professor at Champlain College in Burlington, Vermont. David is a passionate computer science educator and writer. His latest book "Classic Computer Science Problems in Java" was just published recently. We're talking about teaching and learning programming, Swift, Dart, Python and Java, OOP and strong typing, as well as Dave's experience writing books with an established publisher as opposed to self-publishing.

    Three Impossible Things in Computer Science

    Three Impossible Things in Computer Science

    Impossibilities sometimes are as exciting to mathematicians and computer scientists as possibilities. Proving something is impossible defines the limits and tames the vastness of the universe.

    Static and dynamic typing vs. strong and weak

    Static and dynamic typing vs. strong and weak

    There are a few misconceptions floating around when it comes to static typing vs. dynamic typing. Often, the difference is wrongly attributed to the way variables are allowed or disallowed to change their type on the fly. Sometimes, the difference is confused with type "strength".
    In this episode we'll discuss the nature of types in programming languages, and learn why static/dynamic and strong/weak are different.

    What Is Information

    What Is Information

    The more we learn about the nature of information, the more deep connections we discover. It seems like it is sometimes useful to see the universe as information rather than matter.
    In this pilot episode of Codexpanse we will discuss the implications of Claude Shannon's seminal paper "A Mathematical Theory of Communication", talk about the connection between entropy in physics and in information, and fantasize about the future of AI-based communication.
