question:
In topological insulators, one version of this effect gives rise to a defect-resistant current induced by spin-orbit coupling. In graphene, this effect is shifted by one half, giving rise to an anomalous minimum of the relevant quantity, which can allow for ballistic transport. A more complex version of it was discovered in gallium arsenide and can be explained by Laughlin quasiparticles; this is referred to as the fractional version. This effect can be understood in terms of partial filling of Landau levels and has characteristic "plateaus", and it yields numbers called filling factors. Discovered by Klaus von Klitzing when studying a two-dimensional electron gas, for 10 points, identify this effect in which conductivity in a strong magnetic field is quantized.
answer:
Science

question:
An important critique of this work was published five years after its author's death and asserts that much of this work was based on the made-up stories of two teenagers; that critique is by (*) Derek Freeman. Published with a forward by Franz Boas, it was based on its author's time living on the island of Ta'u where she observed that teenagers living in an open and non-secretive society had relatively stress-free lives compared to their American counterparts. For 10 points, name this influential anthropology book by Margaret Mead.

Social Science

question:
Some speculation about the origins of this holiday derives from its mention in the Sanskrit play Ratnavali. In the area of Kumaon, this festival takes the form of a musical gathering. This holiday celebrates an incident in which Prahlada miraculously survived being burned on a pyre, while a demoness who was the sister of Hiranyakashipu was killed. This holiday's main day falls on a full moon, or purnima, during the month of Phalguna. On the eve of the main day of this festival, huge bonfires are lit and cakes made of cow dung are thrown into them. On the morning of this holiday, people frolic with cows to usher in spring. For 10 points, what is this Hindu festival that is highlighted by the throwing of colorful dyes
answer:
Social Science
