This is Internal Pointers. It's a place where I collect all the knowledge I'm gathering through my existence. I've found that writing down things in a well-formatted fashion helps me to better fix ideas in my mind. Topics will range between Mathematics, Information Technology, Finance, Psychology and any other scientific subject that tingles my mind. I don't want to teach you anything within these pages, but if you find something useful you are free to share it. All feedback are welcome.
