[Q]: His work explaining the instability of James Watt's fly-ball governor is regarded as the birth of modern control theory, and his mathematical analysis of the stability of Saturn's rings showed that they could be neither entirely solid nor liquid. He showed how to calculate stresses in suspension bridges and coined the term "curl" to use in the differential form of his most famous accomplishment; however, the only other real work he did on it was the addition of a term for "displacement current. "  FTP identify this British physicist best known for combining his revision of Ampere's Law with Faraday's Law and Gauss's Laws of Electricity and Magnetism to produce his four namesake "equations" governing electromagnetism.

[Q]: One pathway to synthesize this involves the condensation of anthranilate with phosphoribosylpyrophosphate. Cytotoxic T lymphocyte-associated antigen 4 regulates the cytokine dependent catabolism of this molecule in dendritic cells, and consumption of large amounts of this chemical may result in eosinophilia-myalgia syndrome. Its namesake synthase exhibits substrate channeling by passing the intermediate through a tunnel before it reacts with serine. Deficiencies of a certain neurotransmitter can be caused by fructose malabsorbtion in the intestines as it lowers the level of this amino acid in the blood. That neurotransmitter, serotonin, is synthesized from this amino acid as are melatonin and niacin. For ten points, identify this amino acid with an indole functional group.
