> But for fields like math and computer science, all you need is a computer and free time. As someone who has been on both sides, it can be hard to impossible to research mathematics without access to a university library and credentials. Math books are prohibitively expensive and go out of print swiftly. Articles are behind paywalls. Few research mathematicians in my experience respond to requests for preprints or clarification from non-academic e-mails.
