Good opportunity to again promote »The Theoretical Minimum« [1] by Leonard Susskind (born June 1940, director of the Stanford Institute for Theoretical Physics with research interests in string theory, quantum field theory, quantum statistical mechanics and quantum cosmology). It is pretty accessible and a key takeaway is that there is a lot of misinformation in the wild and especially on the internet when it comes to (modern) physics as he tell his class not only once when someone asks about something he read somewhere.
