    CMV: Alonzo Church is criminally underrated and deserves to be labelled a father of Computer Science alongside Alan Turing

    Posted:

    Alonzo Church was easily one of the pivitol figures in the creation of computer science. I don't think his contributions were as impressive as Turing's overall, but I feel still feel like he definitely did enough to garner a lot more recognition and to be known as a "father of computer science" for all the title is worth.

    A few of his accomplishments include:

    1. The invention of λ-Calculus, which was a Turing-complete language that was invented (or at least published) before Turing's Turing-Machines was published. λ-Calculus is the super-essential of PL Theory, a major area of research. If you're not convinced, searching for "λ-Calculus" in Arxiv shows 727 results (compared to 823 results when looking up "Turing Machine").
    2. Proving the Entscheidigungsproblem is undecidable (also independently proven by Turing soon after with respect to publishing dates).
    3. Proving Peano Arithmetic is undecidable.
    4. Being half of the Church-Turing thesis.

    I try my best to have an open mind about these things, so if anyone disagrees, I would love to hear why!

    I also realize that these labels are not really important, and that scientific discovery is a combined effort of countless researchers. And still, it bugs me.

    Best Resources For Learning Fundamentals Of Computer Science?

    Posted:

    Does anyone have a list of good books to have a strong foundation in Computer Science that you would recommend to a beginner? I am starting from fresh, so all recommendations would be greatly appreciated.

    Computer Graphics research ideas

    Posted:

    I will try to get my masters in CS and I am planning to work on computer graphics. I am reading papers and checking out ideas at this stage, to come up with a thesis topic. It would bu great if anyone could help by directing me to recent research topics, recent papers, maybe directly hinting on a topic to study etc. I am planning to work on computer animation, geometric process, etc. kind of things, if that narrowing helps. Thanks for any contribution in advance.

    [N] Google Research’s Novel High Efficient Neural Volumetric Representation Enables Real-Time View Synthesis

    Posted:

    A Google Research team accelerates Neural Radiance Fields' rendering procedure for view-synthesis tasks, enabling it to work in real-time while retaining its ability to represent fine geometric details and convincing view-dependent effects.

    Here is a quick read: Google Research's Novel High Efficient Neural Volumetric Representation Enables Real-Time View Synthesis

    The paper Baking Neural Radiance Fields for Real-Time View Synthesis is on arXiv.

    Questions about Fetch Decode Execute Cycle

    Posted:

    I was watching these two videos and i got confused because certain details are different.

    Video 1 @ 3:30. 5:00- 8:00

    Video 2 @ 2:45

    The difference that confuses me is the numbers in the data column . In the first video it explains the data as a set of 8 bit ,instructions, addresses, and numerical values.

    In the second video it shows a different model where the numbers are a combination of a 4bit instruction and a 4bit address, which is different from the first video.

    I want to know why the difference? Are both models valid? or Is one an oversimplification while the other is correct? What are the implications of this difference?

    For instance, Isn't this limiting the CPU, because the CPU can only have a max of 15 different operations? and the number of ram values is limited also to 15? since the max operation code and address are 4 bits?

    As opposed to in the first model you have separate 8 bit address and separate 8 bit operation codes.

    Also, in the first model if the addresses and instructions are separate does that make the CPU slower? since it has to first load the instruction and then the address in the next cycle? While in the first model the instruction and address are both loaded in one cycle since they are together in one slot?

    what does "high level technical question" mean?

    Posted:

    Sorry if this is a stupid question, but does this mean coding a BST or finding a prime number?

    Database Multivalued Dependencies

    Posted:

    I feel like I'm finding lots of conflicting information regarding MVDs online. I am unsure whether it describes a relationship where multiple values for attribute 'B' exist for a single value from attribute 'A'. Or if it described a table where two intendent attributes are both dependant on a separate third attribute. I would appreciate some clarification or some direction to good sources online. Thanks!
