"Neutrons can dilute the repulsion, while the strong nuclear force can overcome that repulsion to force protons into proximity. According to Sam Kean, the strong force is like the T.Rex because it is strong but has short arms. That is, the strength of the interaction drops off fast with increasing distance, so that as a nucleus swells, the strong force is less able to hold particles together, and so the nucleus splits in a process called fission or emits particles in some kind of decay. "
"Suppose in the dawn of time there was a mixture - a soup or a blob - of protons and electrons floating in space [Concept 1]. Most of space is empty, because these particles are very small. The only force felt by the particles is the electromagnetic force, because it is long-range. The strong force is like glue on the surface of the protons [Concept 2]. If a proton hits another proton, it will immediately stick to it. But protons repel each other due to their like charges, so they never do. Instead, protons attract electrons, which quickly begin orbiting around them like planets, forming hydrogen, an atom with one proton and one electron. This is the basic material of the universe, and the primary element in stars."
"In that respect the strong force is like a spring, harder to stretch the farther you pull it apart"
"Let's take for example Physics. It is widely accepted that there are four major forces that act upon our environment. Those forces are Gravity, Electromagnetic Energy, the Weak Force and the Strong Force. Gravity keeps us on the earth. Electromagnetic Energy is the kind of energy released when matter changes, like when we cook something. Weak Force is radioactivity or the exchange of particles, like the potassium that is released when you cut a Banana. Finally the Strong Force is like the Sun, which is basically a huge nuclear reactor. The truly amazing thing about these forces is that they all must be in perfect harmony, or everything falls apart. Do we believe that it happened by chance?"
"A simpler way to think of the strong force is like Velcro. The force holds things together until a specific distance is reached and then the force goes to zero."
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.
