I have no knowledge what-so-ever of Science. I have wasted my life dreaming. I need to change this, but where do I begin? I want to develop a good general grasp of Chemistry and Physics. I'd like to reach a point where I can contribute intelligently to the discussions on this forum. I am seeking to improve my own self, through knowledge. I would very much enjoy if you could advise me on where to begin on this journey... (Namely which books I should read, which documentaries/videos/lectures I should download or watch). Thank you
