Good low-frequency data will enable major steps forward in our understanding of radio galaxy physics, of the plasma in clusters of galaxies, and of active objects in the high-redshift universe. Such data will also be important in answering some basic questions about the physics of synchrotron-emitting plasmas.To appear in proceedings of "From Clark Lake to the Long Wavelength Array: Bill Erickson's Radio Science". 6 pagesAstrophysicstext
