Ask HN: How to get started with astrophysics

3 pointsby kspeover 6 years ago
I&#x27;ve been reading a lot of Neil deGrasse Tyson, I watch Sixty Symbols and Deep Sky Videos and since being 10 years old I was interested in space&#x2F;exploration. Not mentioning all the sci-fi books&#x2F;movies&#x2F;games I went over. I feel passionate about it, started my own observations with my first ever telescope (it is great!) and I would like to push it to the next level.<p>I wonder which books&#x2F;courses are recommended to start with astrophysics more as a science then ad hoc hobby. I&#x27;ve started the edX program https:&#x2F;&#x2F;www.edx.org&#x2F;xseries&#x2F;astrophysics but there might be better resources (especially books as I&#x27;m more a reader than a watcher).

Welcome to HN! Normally this isn&#x27;t the kind of post that HN encourages (try to stick to stuff that gratifies the intellectual curiosity of the community as per <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;newsguidelines.html" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;newsguidelines.html</a> )<p>Astrophysics relies on a lot of general physics, so many undergrad textbooks on these topics will be relevant to you. Most textbooks you could want are available on the Genesis Library at <a href="http:&#x2F;&#x2F;libgen.io" rel="nofollow">http:&#x2F;&#x2F;libgen.io</a> Thermodynamics and mechanics (especially orbital mechanics) will be important. Choosing a good textbook is important, reviews on stackexchange and other googleable things will help you decide what you want.<p>It seems like most of your exposure to astrophysics has been fairly &quot;popular science&quot; stuff without loads of maths. Fun to hear about, but sort of surface level. For better or worse astrophysics is a LOT of math. You&#x27;ll need strong calculus and algebra skills to really understand most of it. Hopefully I don&#x27;t sound like a pedantic internet prick, I just don&#x27;t know how old or educated you are. If you&#x27;d like to study astrophysics as a science, it might be worth taking a degree in it.
