Elementary particle interact via photon exchange. However, gluons are themselves color-charged, resulting in an amplification of the strong force as color-charged particles are separated. Unlike the electromagnetic force, which diminishes as charged particles separate, color-charged particles feel increasing force. However, color-charged particles may combine to form color neutral composite particles called hadrons. A quark may pair up with an antiquark: the quark has a color and the antiquark has the corresponding anticolor. The color and anticolor cancel out, forming a color neutral meson. Alternatively, three quarks can exist together, one quark being "red", another "blue", another "green". These three colored quarks together
3 Quarks Daily had reached thirty-five thousand. Since then, "3 Quarks Daily" has culled content from hundreds of sources, from blogs such as Salon, Science Daily, and The Huffington Post, from major publications such as "The New York Times", "Nature", and "The Guardian", to smaller outlets such as "Guernica Magazine", "The Awl", and "The American Scholar". The name "3 Quarks Daily" comes from the elementary nuclear particles of physics which in turn were named after the word "quark" which James Joyce had used in Finnegans Wake. The confluence of references to both science and literature in a single word suited the intent of
