Aahhh, Asimov. How I enjoy thee! Here is a collection of somewhat dated but still great essays on science, taken from his long standing column in fantasy & Science Fiction Magazine. These are really good, and the master's logic trails are interesting to study. For example, he narrows down the possible life bearing planets in the galaxy to 50 million out of the few billion stars in the Milky Way, in the ironically titled 'Fifty Million Big Brothers'. Or how he explains why the Sun may have an unknown and unnoticed binary partner orbiting around out there somewhere. There are actually a few theories of this vein floating around out there nowadays, as in Lost Star of Myth and Time. If it sounds interesting to you it will be, if it doesn't, it won't. So be it. Still, science lectures from Asimov should be required reading somewhere if I had to choke down To Kill A Mockingbird in High School. ( )
