Without an external field there are local anisotropies of different orientations due to spontaneous magnetization. Measurements of cosmic microwave background (CMB) anisotropies indicate that the universe is close to flat. Diffusion damping thus damps temperature and density anisotropies in the early universe. While anisotropies on small scales are erased, polarization anisotropies are actually introduced because of reionization. It is an experiment to make large, high-fidelity images of the CMB polarization anisotropies. Bond's most famous work concerns the theoretical modeling of anisotropies of the cosmic background radiation. In 2002 the team reported the first detection of polarization anisotropies in the CMB. Scientists say diffusion damping affects "small" angles and corresponding anisotropies. Using spin-polarized torsion balances, also anisotropies with respect to electrons can be examined. There was no fine structure in the positron fraction spectrum, and no anisotropies were observed. The Spitzer wide area surveys have detected anisotropies in the CIB. The overall effect is to erase anisotropies that occur on smaller scales. Upper limit of such anisotropies of 10 GeV have been provided. These differences in temperature and density are called "anisotropies". His current research is centered around the assembly of multi-nanocomposites with complex anisotropies.
