Life moves too quickly for us pathetic humans, with masses of fascinating activity happening too fast for our meagre brains to interpret. So thank heavens for high-speed cameras.
These marvelous inventions can capture thousands of frames per second, allowing a producer to slow down the footage so we can see exactly what happens when someone is punched in the face. One second of action can be played over several minutes, and without any apparent loss of playback smoothness--so we can see what it looks like when you throw tiny pies at a wasp. Now that's progress.
