Why yes, yes I do. While doing a quick back to the future check-in yesterday on Carl Sagan and Cosmos for my post on Phoenix and Mars, I learned that one of Sagan’s children, his son Nick Sagan, became a writer. Nick Sagan has written for the large and small screen, television, award winning science fiction and a very intriguing recent work of non-fiction titled You Call This The Future?: The Greatest Inventions Sci-Fi Imagined and Science Promised. I’ve always thought that the most common such invention was the cell phone. Yup. I loved Star Trek as a kid and what are cell phones but the real life realization of the communicator (minus the other worldly range)? And now you can even get one Bluetooth compatible!
