Example Input: This quantity can be defined as minus the temperature times the derivative of entropy with respect to particle number. The Gibbs factor is a generalization of the Boltzmann factor that takes this quantity into account. Usually defined as the derivative of the Helmholtz free energy with respect to particle number, FTP name this quantity which governs particle flow, as particles flow from systems with higher values to systems with lower values.
Example Output: Science

Example Input: Melamine resin is formed by dehydration of this compound, while barbiturates can also be formed by addition of this compound to malonic acid. Other uses of this compound include separation of racemic mixtures. Originally produced by a reaction between silver cyanate with ammonium chloride, it is now made in indusrial quantities by heating carbon dioxide with ammonia. When arginine is split, it forms an ornithine molecule and a molecule of this; the principal end product of mammalian nitrogen metabolism. First isolated by H.M. Rouelle, FTP, name the compound used to disprove the theory of vitalism when, in 1828 Friedrich Wohler, first synthesized it from inorganic materials.
Example Output: Science

Example Input: Images observed in 1996 found that this object emits two streams of polar winds which initiate a shock front dubbed a dancing sprite by scientists. In January 2003, Titans transit of it allowed astronomers to use this objects x-rays to measure that moons atmospheric thickness. Iosif Shkolvsky suggested that synchrotron radiation could be emerging from this remnant of SN 1054, a supernova discovered by Chinese astronomers. For 10 points, name this first member of the Messier catalog, a pulsar wind nebula found in Taurus and named for a crustacean.
