<p>I think you should read the book by Dava Sobell.  It will give you perspective and lead you to original source materials.

Or you could watch the British television series from 2000, [Longitude](https://en.wikipedia.org/wiki/Longitude_(TV_series))

<p>I am a lyaman of Geography, and working on a project to calcuate
x,y (from a rectangle coordinate system) to Lat,Long
I searched on the net, and fell complete lost in the big world of geometry, geography, and mathe.
Could someone please recommend books/pdf on learning these stuffs from a newbie?
Thanks!</p>

They even have their own stackexchange website, https://gis.stackexchange.com ! Conversion between coordinates is not always very straightforward and can involve some hard mathematics; you can try here https://epsg.io/transform#s_srs=4326&t_srs=3857 for one example of (lon,lat)->(x,y) conversions, but there are many (lon,lat) and (x,y) reference systems. As a bonus, if it's just to find how an image relates to a map, try georeferencing, https://www.youtube.com/watch?v=jKLBFddpTGI . (plus, your question is a bit open-ended, hard to see what a right answer on this site should be!).
