To judge from reports in the popular press, every scientific advance is either epoch-making or disastrous. In fact, science generally progresses rather like an amoeba, throwing out occasional pseudopods in directions that look promising, and then either pulling the rest of the body after, or retreating. This talk will focus on three issues that have made the science columns of newspapers in the last year or two, explaining how we came to our present understanding of cosmology (the large scale structure and evolution of the universe) and of the energy sources in stars and the progress being made on the very curious and puzzling phenomena of bursts of gamma rays coming from random directions in the sky, seemingly uncorrelated with anything else we know about.
