This term refers to an anisotropy of the CMB that is caused by the motion of the earth through space.
This term refers to an anisotropy of the CMB that is caused by the motion of the earth through space. The power radiated by an oscillating one of these is proportional to the fourth power of the frequency, which is a principle used in television antennas. The atomic model of a dielectric posits it as a collection of several of these, which align and create a field opposing the external field. Their electric field falls off as one over the third power of the (*) distance. Placing one of these in an electric field creates a torque equal to the cross product of the field with these configurations' namesake "moment". For 10 points, identify this configuration consisting of a positive and a negative charge bound together.
