"Nitrogen is Like carbon, nitrogen is an essential element for life processes."
"Nitrogen is like a cold-blooded, lethargic person--it combines with other substances very reluctantly and with but little energy. Oxygen is just its opposite in this respect: it gives itself freely; it is "Hail, fellow; well met!" with most substances, and it enters into co-partnership with them on such a large scale that it forms nearly one half of the material of the earth's crust."
"You can think of a DNA molecule as a ladder. The sugar and the phosphates make up the sides of the ladder while the nitrogen bases are like the rungs."
"The nitrogen cycle is like a French movie; it's difficult to understand, overly-complicated, and in desperate need of translation. One reason the nitrogen cycle is so tricky is the terminology. Denitrification, nitrification, ammonification, nitrogen fixation: they all blur together like the colors in an impressionist painting."
"The nitrogen cycle is like the phosphorus and carbon cycle because they both show how important substances are moved around in the environment."
in which soil organisms are the workers. They take atmospheric nitrogen and oxygen as raw materials and put them together to form nitrates(NO3).
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.
