According to this article, Barry Goldwater’s book, The Conscience of a Conservative, is being reissued. Timely reading? Depends on what audience at which this is aimed. I seriously doubt conservatives of the Rove/Norquist stripe will have much sympathy with Goldwater, who now seems admirable and even iconic compared to the…
In an article recently published on BldgBlog (HT: Boing Boing), there's an absolutely fascinating interview with Michael Cook, a Canadian writer and photographer who devotes himself to exploring the subterranean infrastructure - that is to say, the storm sewers, spillways, abandoned hydroelectric complexes, dams, and all manner of tunnels and…
I'm planning on packing my camcorder and asking a few dozen random people some questions to test their knowledge on various topics. I'm doing this because I suspect that many people lack basic knowledge regarding important topics. Other questions are geared to checking people's attitudes regarding important issues. Below you…

Anybody recognize that? Where it comes from? What it refers to?
This past weekend was the 100th birthday of Robert A. Heinlein. I was not there, though I’d wanted to be. You see, Robert A. Heinlein was one of the greatest science fiction writers in the world, and when I was a child, his books informed my apprehension of just about everything. It might be questioned whether one man deserves the kind of press Heinlein gets. Even when he was alive (he passed away in 1988) he was controversial but there were still many places you could walk into where not a soul would know who he was. I think he’s important because, in a way, he made modern America.
What? A science fiction writer? Made America?
Such a statement demands clarification.
A biography is soon to be out by a gentleman named Bill Patterson. You can read it, read about the man who once wore the title “The Dean of Space Age Fiction”, and judge for yourself. I won’t go into huge detail about his life or work here. I want to make a smaller, more pointed observation.
In 33 novels and a significant number of short stories, Robert A. Heinlein established a didactic approach to science fiction that has been copied, improved, debated, revered, and hated since he began his career in 1938. Heinlein was born in Missouri. He graduated from Annapolis. He received a medical discharge from …
[This idea was born as a comment here, but I decided to create a separate post out of it]. What if your mother stood right behind you, and your mother's mother stood right behind her? Then your great grandma and then your great great grandma. Imagine them all lined up, one foot apart, stretching out into the distance. If a generation is deemed to be 25 years, a line of your ancestors as long as a football field (300 feet) would stretch backwards 7,500 years. The woman at the end of that 300 foot line would have lived during the time when agriculture just began in ancient Egypt. You'd still recognize each of your ancestors in that 300 foot line to be fully modern humans, biologically speaking. Isn't it amazing to think that you could run along side that entire 300 foot line of your ancestors in only 15 seconds (I'm assuming you’re not an Olympic caliber sprinter) to end up standing next to one of your own ancestors who was alive 7,500 years ago? Now think even further back. In An Ancestor’s Tale, Richard Dawkins calculated that 20,000,000 great-grandparents ago, our relatives were small shrew-like animals living at the end of the Cretaceous period. What if you spaced out your relatives one foot apart to extend all the way back to these shrew-like creatures? That line would be 3,787 miles long. That's about the length of highway running from my hometown of St. Louis, Missouri to Anchorage Alaska. Imagine speeding alongside that line of your relatives at 60 mph, seeing the generations of your relatives whizzing by, more than 5,000 of them every minute. It wouldn’t take long to reach the last of your relatives who looks like you. In fact, your trip would have barely begun. Biologically modern humans (those whose bodies are the functional equivalent of our own bodies) came onto the scene between 100,000 and 200,000 years ago. Driving at highway speed parallel to that line of your own relatives, you'd run out of your biologically modern human relatives less than one-minute after beginning your trip. That's only 4,000 generations. [More . . . ]
