artist was inspired to found a movement in his correspondences with Eva Watson-Schutze. In one exhibition of his work, he claimed "I am an American. . . the search for truth is my obsession. " He executed a series of abstract, subject-free works called Equivalents. One of his works shows a narrow gangway that separates an upper deck of men from a lower deck of women and children on a boat. This artist of The Steerage and founder of the journal Camera Work also depicted a certain woman holding her hands to her face and clutching a cattle skull in many photos. For 10 points, name this Photo Secession founder who took many pictures of his wife, Georgia O'Keeffe.
Fine Arts

The vertical component of the effect caused by this force is sometimes named for Eotvos. The ratio of inertial forces to the magnitude of this force is a dimensionless number named for Rossby. This force causes the apparent (*) deflection of objects moving in rotating reference frames. For 10 points, name this fictitious force that causes winds to deflect to the north and south of the equator, which is responsible for the formation of cyclones.
Science

Euler's proof of Fermat's Last Theorem for the n equals 3 case involved extending integer arithmetic to one of these structures, which contain numbers of the form a plus b times the square root of negative 3. Dedekind defined an ideal complex number based upon a property related to these structures and Hilbert utilized (*) polynomial ones to solve his Basis Theorem. The advent of quaternion algebra and the extension of the axioms of this structure to square matrices led to the formulation of its non-commutative theory and the first single theory of the abstract commutative variety of these structures was proposed by Noether. FTP, what are these mathematical objects defined as a set containing two operators that satisfy a collection of axioms.
