The lectures are currently being presented and as they are , we will load them into this site so go to each individual lecture page and click on the icon which is the front page of each lecture and this will load the pdf of the powerpoint slides. The quicker way to that if you are on this page at this point is to click on the icon below and this will take you directly to each pdf. But if you know what you want then simply go to the relevant lecture. 6 have been posted in 3 sessions. We now have week off and then we will post the final six beginning on the 28th January
