"An analogy I like is that your body is like a chain link fence. Visible light is like tennis balls - they are big and hit the fence but bounce off. Gamma rays are like bullets from a gun - they are tiny and often pass through without hitting anything, but they are very energetic and if they hit something they will destroy it."
"An astronomer who only studies visible light is like someone who could only hear one particular note in a Beethoven symphony. Infrared astronomers can hear a much wider part of the symphony of the Universe. They can detect what would be analogous to all the notes played in the bass clef."
"A useful analogy: visible light is like playing only the 3 middle keys of a piano."
"Seeing only visible light is like listening to music in 1 octave=new lab motto."
"The problem is that both light we can see and light we can not see have the potential to damage our eyes. Visible light is like the colors of the rainbow, while invisible light is called "ultraviolet light" (uv rays) and while it can't be seen can still wreak havoc with our eyes. Too much of the wrong kind of light can lead to cataracts, macular degeneration, or, sometimes, melanoma around the eyelids."
"Confining our perception of nature to visible light is like listening to music in only one octave," Tyson said as he closed the episode. It was a nod to the diversity and pluralism that science thrives on, a diversity of people, ideas, religions, and perspectives.
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
