It's not childbirth, but one god of this domain had a name mistranslated as "placenta king," and displaced an older god of it named Iah. During the Middle Kingdom, this domain was represented symbolically by a lake at Karnak, and by the youngest member of the Theban Triad, who was the son of Mut and Amun. One god of this domain allowed Kheru-Ur and four other new deities to be born from Nut after losing one seventy-second of his power, elongating the year by five days. This realm was represented by Khonsu, who lost a gambling game to Thoth. This object also corresponds to a body part removed in combat with Set. For 10 points, name this cosmic object which ancient Egyptians equated with the ripped-out left eye of Horus.
Social Science

Iannis Xenakis used eight so-called "sound complexes" in a solo work for this instrument called Nomos Alpha. Six beats on the body of these instruments begin the main theme in Arvo Part's orchestration of Fratres for twelve of them. An ensemble consisting entirely of these instruments was founded in the 1970s by twelve members of the Berlin Philharmonic. The first of Villa-Lobos's Bachianas Brasileiras was composed for (*) eight of these instruments, while Jacqueline du Pre popularized Edward Elgar's concerto for it. J.S. Bach's six unaccompanied suites for this instrument were famously recorded by both Mstislav Rostropovich and Pablo Casals. For 10 points, name this instrument played by Yo-Yo Ma which joins two violins and a viola in a string quartet.
Fine Arts

Harnik et al. argue against the anthropic principle by proposing a universe that lacks this. One instance of this interaction is modeled with a unitary matrix that includes three mixing angles and a complex phase that models CP violation. A vector minus axial Lagrangian for this force leads to maximal parity violation, making this force only affect left-handed particles. This force is responsible for quark flavor changing, was unified with electromagnetism by Glashow, Weinberg, and Salaam, and is transmitted by the massive W and Z bosons. For 10 points, name this fundamental force involved in radioactive decays.
