Title: Dark Energy and Dark Matter: Chicago, AAS, and UCLA


Evidence for an accelerating universe and a dark energy component includes the supernova distance-redshift relation and now, though less precisely, the cosmic microwave background fluctuations, large scale structure, and the age of the universe. Papers on dark energy have been appearing on astro-ph at 2-3 per week. I review some of the recent ideas and projects presented at conferences in the last four months.
