The problem was that I had never had calculus, much less differential equations. I fact I didn't know what calculus was; I only knew it as a word that meant "really hard math". So I made it about five pages in and realized that I had no chance. BMW stayed on my bookshelf.
Ten years later, I was in a graduate program for aerospace engineering and had finally made it through all the pre-recs for 600-level astrodynamics. BMW was one of the textbooks for the course. The moment, a month into that class, when I opened the book and it actually made sense was one of the highlights of my life, and that copy of the book I bought as a teenager is one of my most prized possessions.
I’ve read through a couple textbooks front-to-back on topics that are completely unrelated to my field[0]. A good textbook should be able to explain tough concepts while engaging the reader with interesting content and relation to the world.
0: I quite enjoyed Anthony J.F. Griffiths et al’s Introduction to Genetic Analysis, despite never taking a genetics or even biology class.
Then I had a professor who had an accent I struggled to understand. Thankfully, she picked a fantastic Linear Algebra textbook. That's when I realized that the textbook is debatably the most important part of a class (at least for math and science).
So I would just solve it during class. Teaching myself from the book.
One day assignment wasn’t on board. So I asked her for it so I could do it during class.
She was confused and asked me how I was going to learn the material if I wasn’t paying attention.
Well it turns out people get really upset when you logically explain how you don’t need them since the book teaches it just fine.
Better just to search for the subject on reddit.
Turned out to be really useful when I studied planetary science in grad school - just knowing the language of the coordinate systems and expansions.
Later, I picked up a copy of Mattias Soop's sweet monograph, "Introduction to Geostationary Orbits" ... even today, it's a joy to read.As the author mentions, you can pick up a copy for well under $20. I'd say it's worth it for the 1960s-style diagrams and figures alone!
It's a Dover edition. They love getting textbooks that are decades old and making inexpensive but decent quality paperback editions. In fast moving fields Dover editions may be out of date, but if the fundamentals haven't changed much a Dover book can be a great way to get started.
To a good first approximation if you are interested in some area of STEM and would be fine with an approach that doesn't include the last couple of decades are so of developments Dover is a good place to start.
I bought it from an upperclassman for 25 cents.
Still on my shelf and I used it to design my own astrodynamics course to teach during grad school.
> I’d say if you’re starting out, go with BMW, and if you want to get more advanced, go with Schaub and Junkins
I'd replace BMW with Curtis here.
The search results for "astrodynamics" [1] include several of ht ebooks listed above; clicking on the entry for Bate shows the co-assigned books, which inlcudes all of them.
