The exercise classes will start ¡­

The exercise classes will start Friday next week (the 25th of January). We will start in Peisestua (303), but will move if we are too many. Remember to do the following before the exercise: Go out at night and look up at the night sky. What conclusions can you draw on the size, age and evolution of the universe from what you see? We will discuss your findings in the first exercise class.
