Unreliable evidence
ExhibitionsI hadn’t really thought much about pixels before, despite spending a large portion of my day looking at them. After all, a pixel is just a tiny unit in a digital image, and we all tend to look at the bigger picture. But how about this: this humble unit has now become a key feature of drone warfare. Drone-fired missiles have reportedly been developed that can burrow through targeted buildings, and leave a hole that appears smaller than a pixel on publicly available satellite images. This means that drone strikes are often invisible to groups who try to monitor attacks, such as NGOs or the UN.
