Science and Technology in War

Still, if you will not fight for the right when you can easily win without bloodshed, if you will not fight when your victory will be sure and not so costly, you may come to the moment when you will have to fight with all the odds against you and only a precarious chance for survival. There may be a worse case. You may have to fight when there is no chance of victory, because it is better to perish than to live as slaves.
Winston Churchill

Thunderf00t has an interesting video about the role of technology in war — using the example of a magnetic mine in World War II.

Very interesting to watch — if you wonder about people’s contributions in a war, there is a lot to be said about the scientists and engineers who develop “better” ways to kill and avoid being killed. Of course, ideally, these things would not be used. But as Churchill put it so aptly, sometimes you do not have this luxury.
