A swarm of diamondbacks fire their "railguns" at a train.
In the Starcraft 2 campaign, there is a unit called the “diamondback”. It’s a sort of hovertank, and it is useful for hunting down other vehicles because it is armed with dual “rail guns” that can fire while it moves. In the game, the rail guns are depicted as some sort of energy weapon: they fire hot blue beams at the target. This disturbed me because rail guns actually do exist, and they most certainly don’t fire blue energy beams!
So what’s a real rail gun and how do they work? I’m so glad you asked!
By now, you have probably seen the absolutely epic Starcraft 2: Ghosts of the Past trailer. If not, take a look at this, and pay particular attention to the depiction of Sarah Kerrigan’s cloaking device at about 11 seconds in:
Cloaking is common in science fiction: Star Trek pioneered it with the Romulans, and other popular franchises like Star Wars and Predator and Halo have used it. And of course in Starcraft and Starcraft 2 both the Terrans and the Protoss have a whole variety of cloaked units. But could it really work? You may be surprised to learn that the answer is yes!
Obviously, this sort of technology would be extremely useful for the military, so they are funding research into technologies that could make it a reality. There are basically two ways that you could achieve “cloaking”. The first way would be to actually divert light around the cloaked object, so that it appears not to be there. Continue reading
Hello and welcome to The Science of StarCraft! There’s tons of stuff in the StarCraft universe, both from the original games and the new one, that I can’t wait to talk about here, but I thought a good place to start would be the StarCraft 2 teaser cinematic.
If you haven’t seen it, here it is:
You’ve gotta love the space marines. They’re the first armed boots on the ground when you start a game, they’re in the thick of even the most epic battles, and they’re the last resort when your base is crumbling around you. So it’s great to learn more about how they work!
This video actually tells us a lot about the technology involved in building a marine, and about the level of Terran technology overall. Marines are about as basic as it comes for terran units, but there’s some pretty high-tech stuff going on here, so we can only imagine what goes into, say, a battlecruiser!
Let’s jump right in and start dissecting this video to see what we can learn. Continue reading
