I checked out the episode, and damn, was Straka ever straight on.
From screwing up the calculation of how fast a rock launched by a trebuchet is if it flies for 5 seconds, to people confusing railguns and coilguns at least a dozen times in the space of a few minutes, this show has to be one of the biggest piles of rubbish i've lately seen in "educational" television.
While it's not quite as bad as saying that turning every statement around 180° is better, take everything said on that show with a huge mountain of salt.
Just to elaborate one of the most ridiculous errors: above mentioned trebuchet calculation. They explain how a stone has more kinetic energy the longer it can accelerate in gravity. And how it travels at 30 feet per second for every second of fall. Then they launch one in a trebuchet and show how it makes a bigger crater in sand. And claim that the stone flying for 5 second when launched, thus reached a velocity of 150 feet per second. Which is an error that would be hugely embarrassing to make in the first high school physics test, let alone on TV.
Though one guy being the science advisor to Battlestar Galactica explains a lot about that show too.
