ohh thanks for the replies.. i had an internet black out so i haven't been online for days... so.. independence from the mass of the second object isn't really true... it's just negligible... i get it now, thank you :)
I'm talking about "Mathematical Tools for Physics by James Nearing".
https://www.amazon.com/dp/048648212X/?tag=pfamazon01-20
it seems it cover lots of math... but it feels like it's just a reference book..
will it be enough?
or should i get more specialized books to learn each subject thoroughly?
my current skills in math are differential eq and linear algebra...
and I am about to start reading Feynman lectures of physics and planning to read all John Baez's recommended books.. after reading Feynman's, what would be the next best thing to do? learn more math? or jump already to core...
is there other theoretical physicist that is both particle physicist and cosmologist? i only see randall sry i just need a quick answer.. anyways, ill be skimming all female scientists in wikipedia
