year after the Big Bang. The first paper presents initial results; the second, final results. Presents results from the Differential Microwave Radiometer (DMR) on the COBE satellite. This maps the cosmic radiation and searches for variations in brightness. The CMB was found to have intrinsic "anisotropy" for the first time, at a level of a part in 100,000. These tiny variations in the intensity of the CMB over the sky show how matter and energy was distributed when the Universe was still very young. Later, through a process still poorly understood, the early structures seen by DMR developed into galaxies, galaxy clusters, and the large scale structure that we see in the Universe today. The first paper presents initial results; the second, final results. Presents results from the Diffuse Infrared Background Experiment (DIRBE) on the COBE satellite. This searches for the cosmic infrared background radiation produced by the first galaxies. Infrared absolute sky brightness maps in the wavelength range 1.25 to 240 micrometres were obtained to carry out a search for the cosmic infrared background (CIB). The CIB was originally detected in the two longest DIRBE wavelength bands, 140 and 240 micrometres, and in the short-wavelength end of the FIRAS spectrum. Subsequent analyses have yielded detections of the CIB in the near-infrared DIRBE sky maps. The CIB represents a "core sample" of the Universe; it contains the cumulative emissions of stars and galaxies dating back to the epoch when these objects first began to form. Atomic and molecular physics James Clerk Maxwell reviewed this work in Nature and concluded that "there can be no doubt that the name of Van der Waals will soon be among the foremost in molecular science." Johannes Diderik van der Waals received the Nobel Prize in 1910 for his work on the equation of state for gases and liquids. Discovery of X-rays, leading to the very first Nobel Prize in Physics for the author. The classic experimental measurement of the mass and charge of cathode ray "corpuscles", later called electrons. Won the Nobel Physics Prize (in 1906) for this discovery. Zeeman (1897) papers Described the famous effect of splitting of spectral lines in magnetic fields; earned author a Nobel Physics prize citation (1902). Planck, Max (1901).

This announced a law that gave decisive evidence for atomic number
