We have found the way to (some of) your scientific hearts at long last — with science fiction. After Tuesday’s podcast on why science fiction matters went live, we heard from quite a few of you guys. Which we love, because sometimes while we’re recording these sessions in the sweat-inducing podcast studio, it seems like we’re operating in a vacuum.

But we know that’s not the case. Not when you write in to give us a well-deserved tongue lashing for not including science-fiction master Robert Heinlein during our initial session. Don’t worry, we’ll get to him. There will be more of these. The point of this first one was to discuss a few favorites and get the conversation rolling.

We’re edging closer to 200 episodes of TechStuff. It’s hard to believe Chris and I have sat down at those microphones 200 times to bring you information on technologies ranging from particle accelerators to the cutting-edge technology in the year 1510. This week, we responded to listener requests for episodes focusing on traffic overlays on Google Maps and plasma torches.

In case you’ve missed it somehow, today is the 30th anniversary of the release of “Pac-Man.” Blogs are buzzing, and Google has put up its most interactive doodle. And I’ve had an important revelation.

Since starting this blog, I’ve been thinking about my own history as a fan. When was the first time I really felt like a fan of something? My most fannish moments are easy to chart, and some of them are still too embarrassing to announce publicly. But today, my first fandom became obvious: It was “Pac-Man.”

Spiders are amazing creatures, and the ability to spin and navigate a web ranks up there near the top of insect capabilities. In the following video you can see a spider spinning the classic web and avoiding stickiness…

Today I’m writing about the longest cave system in the world, which is located in central Kentucky, where I’m kin to, like, everyone. Lovely country. Grassy hills that ripple to the horizon. Crooked black barns and hay rolls. Horses. My granddaddy’s garden tomatoes.

But I digress from what’s beneath: more than 367 miles (590 kilometers) of limestone tunnels, aka Mammoth Cave. Let’s get straight to the mummies.

Earlier this week, I heard about the South Florida teen who shaved her head to make a statement as well as a boom — a hair-stuffed oil boom fashioned to soak up the mess that’s still pouring into the Gulf of Mexico. Since there’s always been a place for strange hair stories on this science blog (“No poo”! Hair mats!), hair booms seem like a logical topic to discuss.

When it comes to the topics we choose to talk about in our High Speed Stuff podcast, Ben and I really make an effort to be as varied as possible. Just scroll through the wide-range of subjects we’ve covered in the past 150 episodes for proof of that. So maybe that’s why I simply can’t believe we haven’t discussed boats — up until this week, that is. Yes, in the past we’ve talked about plenty of amphibious cars, but we never dedicated a full episode strictly to boats. And I think we’ve jumped into the water head-first on this one…
