PROBLEM: The earliest discovered writings on these were in the Hittite language and were authored by Kikkuli of Mitanni, while Gryson, an expert on these, helped Xenophon to write two treatises on the subject. Tupac Amaru II and Francois Ravaillac were both executed using four of these, and one of these named Incitatus was legendarily appointed as a Roman senator by Caligula. The Avars brought an invention that eased their use to Europe, and huge masses of these were instrumental in saving the French army at Eylau. Many cities were named after of these owned by Alexander the Great, Bucephalus. For 10 points, name these animals used to transport hussars and knights.

SOLUTION: Literature

PROBLEM: A weight of the nth power of this parameter is imputed to contributions to elements of an S matrix by nth-order Feynman diagrams; thus, this number can be considered the order of expansion in perturbative quantum electrodynamics. This constant is a measure of the electron anomalous magnetic moment, which explains its role in the relativistic splitting of atomic spectral lines that is its namesake. The coupling constant for the electromagnetic interactions of electrons, it is equal to the square of the ratio of the electron and Planck charges, or, in cgs units, the electron charge squared divided by the speed of light times Diracs constant. For ten points, name this physical constant usually denoted alpha and equal to about one over one hundred thirty-seven.

SOLUTION: Science

PROBLEM: Though not Max Scheler or Henri Bergson, this philosopher used the term Homo faber to refer to man's ability to control his environment through tools in one work, which sought to contrast the vita activa with the vita contemplativa. This thinker also wrote a work which posits that certain anti-utilitarian institutions are inexplicably stable from their shapelessness, and that one man only had to resort to violence because of Ernst Rohm's homosexuality. That work also coined the term "secret societies in broad daylight" and dedicated a section to the secret police. This author of The Life of the Mind and The Human Condition also used the phrase "banality of evil" to help explain the Holocaust. For 10 points, who is this author of The Origins of Totalitarianism and Eichmann in Jerusalem
