Hello, my name is Johann Salas, i´m a civil engineer from university of Antioquia, i´m developer in python and passionate of modern physics. I have been teaching classes for more than 10 years and as I was learning new things I made an effort to show them to all those who need them.
when i teach i like the student fall in love with what they are learning, not only mechanize mathematical procedures but also understand what I am doing, what it is for and above all, why I should do it, so I focus the teaching on a dynamic understandable without the crudeness or superficiality of traditional teaching.
