Wikipedia articles about history or science are usually pretty good . They are a good place to start and it ' s usually what I read first . How much math have you studied and what do you want to learn about next ? And recently I ' ve just wanted to learn about politics in different countries , but not just from a news stand point . Like the unbiased complete history of them . And geography etc . Geography is easy to learn about online . Google maps are great , especially the satellite images . You can google for photos of almost any interesting feature in the world . The other parts sounds like you want to get a PhD in history or political science . That ' s a big topic ! Oh , and good luck finding unbiased history . Usually the best you can do is to read bothall sides of an argument . Getting access to a research library at a good university will be helpful .
