About the only thing in our development that comes to mind is that you may not have a stable equivalent of the North Star, so navigation would be harder (but you'd need a fairly large relative speed for that to really be the case). As long as you had an iron core, magnetic navigation would still work, you just might explore the world a bit more slowly (without an iron core, being cooked by radiation would be an issue).
Newtonian mechanics came from things in the solar system, rather than beyond. Having a large gas giant that cleaned up the solar system (so there's just one other planet left) would be more of a problem than a rogue star.
General relativity was first demonstrated with gravitational lensing during an eclipse, but that wouldn't be affected (though we are very lucky in our moon for this and various other reasons). But it was later demonstrated by GPS satellites, so even if you missed the eclipses then you'd get a later chance (fun fact: original GPS satellites had a backup mode in case Einstein was wrong).
The question that bothers me is whether the opposite of this. In China, science effectively stalled for hundreds of years because they didn't invent glass, which was a prerequisite for most of chemistry. Perhaps there's something that's really obvious to people on a rogue star that's the equivalent of glass for us and is the thing that you need to unlock an entire field of science that we simply are not aware that we miss. For example, a simple way of synthesising bosons would enable trivial low-radiation nuclear power, but we have no idea how to do it. Maybe if you observe the galaxy from a different vantage point, it takes you down a path where you discover that it's easy.
