Hey All I'm Portuguese, became acquainted with physics during elementary school, reading books and magazines around the house, namely Science&Vie and school manuals from elder family members. Physics, Chemistry, Maths and Universal History are my favorite topics. My first science book ? Hubert Reeves, Patience dans l'azur/Um pouco mais de azul. https://www.goodreads.com/book/show/1342326.Patience_dans_l_azur[/URL] [Broken] Favorite authors ? Feynman, Sagan, Penrose and Magueijo. Honorable Mentions: A.C.Clarke and Asimov. Posters in my room during adolescence ? Albert Einstein along Steffi Graf. Later, I pursued a career in computers and engineering and lost focus. 25 years later, it's time to get back to basics, to read, learn, and focus on my true love, science, physics in particular. I hope to use this forum as an active member. Hi All !!
