Welcome to this course. I hope you get inspired by astronomy. Even if you are not an astronomy buff, you might end up falling in love with it. I started my student career thinking to be a writer or a film director (see a cartoon-animation that NASA did interviewing me) until I fell in love when one of mine professor taught particle-physics in a complete 'artistic' way of teaching. What stars, galaxies has to do with Maria Callas? Or Rembrand? Come and find out in this course...browse the different pages to learn how the course will be taught. I am especially looking forward for our Debates (6 of them!) on who will win: dust vs dark matter vs magnetic fields...
