This video isn’t conventional computer tech. And yet’s immensely technical, invoking a principle of physics. Gotta love that. And so, if you’re camping, don’t have matches, can’t find a flinty rock and can’t get your campfire started for a cold night to come, here’s a really cool demo. What you need is some pulverized wood, a clear plastic sandwich bag, and some water from a nearby stream. Or your cooler. Sound impossible, Mr. MacGyver? Check it out.

· · The Mac Observer's Background Mode Podcast

Jennifer Ouellette is a freelance science writer, editor and book author. Her work has appeared in Physics World, Discover, New Scientist, Physics Today, Salon and Nature. In 2010, she published the book “The Calculus Diaries: How Math Can Help You Lose Weight, Win in Vegas, and Survive a Zombie Apocalypse.” With a degree in English literature, Jennifer didn’t start out intending to be a science writer. But thanks to serendipity, she landed her first job with the American Physical Society who discovered she could write really well. The thinking was that it would be easier to teach her physics than teach physicists how to write! It opened her eyes to the field. So how does one become a famous science writer? Jennifer tells a great story.

That means looking at certain facts with keen understanding and, more importantly, updating our estimations based on new facts. John, as you might expect, gets into physics and Bayesian logic. But don’t worry. It’s a fun ride.
