Hi I remeber a story I started reading a couple of years ago about a person that was reborn in a new world. The world is a magic universe were people can use magic but it was banned by the church which control most of the world. The distrinction I remeber that got me hooked was that unlike other story, were magic throu science out the window this worlds magic is completly bassed on science. Learn more about atom, particals, wave, body function, etc will in turn increse your magical ability. Not to spoil to much for the once that have not read it but the protagonist try most of the begining to secretly learn about magic while staying bellow the radar of the church while he later tried to get to a magical academi that sounds like an university whit students, proffessors, teachers, etc.
