    What's great about Computer Science? Other than Computer Science

    Posted: 01 Jul 2021 06:26 AM PDT

    So I'll be studying CS at University soon. I'm excited, and at the moment I want to consume myself with CS related content.

    I watch all the 'day in the life' videos (highly fabricated, I know), vlogs etc about the subject.

    I'm not struggling with motivation, I just want to find out more about CS, that isn't actually study based, I think I'd crash if I tried to learn another thing at the moment.

    With that being said, what do you enjoy about CS, that isn't actually 'work' related?

    How are computational neuroscience and machine learning overalapping?

    Posted: 22 Jun 2021 08:02 PM PDT

    Hi, I am an undergrad with a background in neuroscience and math. I have been very much interested in the problem of AGI, how the human mind even exists, and how the brain fundamentally works. I think computational neuroscience is making a lot of headwinds on these questions. Recently, I have been perusing some ML labs that have been working on the problems within cognitive neuroscience as well. I was wondering how these fields interact. If I do a PhD in comp neuro, is there a possibility for me to work in the ML and AI field if teach myself a lot of these concepts and do research that uses these concepts?

    Btw I get these are hard questions to answer and I won't be able to answer them completely and probably work on a small part to answer it. I am ok with that.

    Why doesn't the output match the expected one when computing the standard deviation in CPP?
