"Every once in a while, decaying uranium nucleus gives off a neutron. This extra neutron is like a bullet. If it strikes another uranium nucleus, it can split the nucleus in half. Splitting the heavy uranium nucleus is called nuclear fission. When nuclear fission takes place, an enormous amount of heat is released, along with lots of radioactivity."
"neutron star is like a gigantic atomic
nucleus, packing more than a solar mass
of neutrons inside a ball just 20 kilome-tres across"
" On the astrophysics side, he focuses his attention on black holes and neutron stars, he said. Both are examples of high density matter. A neutron star is “like the mass of the earth compressed into a sugar cube,” he said. It's a unique opportunity to make scientific breakthroughs."
"A neutron star is like the star that tried to be a black hole, but failed."
"A neutron star is like packing our sun and its sister down to something smaller than most asteroids, with a density so high, a single cubic centimeter of a neutron star outweighs the entirety of Mount Everest."
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.
