NIGHT FEVER
What do horror movies, home invasions, alien abductions, and special operations missions all have in common?
They usually take place at night.
Evolutionarily speaking, humans are not nocturnal creatures. But our ability to produce tools has allowed us to create artificial, if not perfect, adaptations to our environment. In the case of darkness, our first adaptation the dark, we figured out how to extract light the dark, by amplifying barely perceptible traces of ambient light and converting infrared light into visible photons. Thus was born image intensification technology, or I2, colloquially known as night vision.
