Ultrafast cameras streak ahead

According to the old adage, "a picture paints a thousand words". And in many scientific disciplines ultrahigh-speed imaging is the only reliable way to visualize the countless physical and mechanical processes that occur on microsecond timescales. Such processes include ballistics, the propagation of cracks in materials, flame fronts in combustion research, the generation of shock waves in aircraft components and electrical "streamers" in high-voltage research.
