Up till now, what you've seen has been very much built with the physical intuition you get from just looking at the world around you. But all that hard won intuition is not going to help you here, where we extend into the unfamiliar world - the world of the very small which is quantum mechanics. Its not that your physical intution is wrong - it just needs extending when we move to more extreme environments.

Questions? if its something that comes up in the lecture - notation or something quick - then just come and ask at the end. We might have to move out of the lecture theatre but we can keep talking in the area outside. Or come and see me in the office hour, or if that time doesn't work for you then email me (chris.done@durham.ac.uk) and we If its a question that comes up as you are going through the lecture notes in your own time then first try to understand by looking in the book or on the web (but beware of nutters!). Or try asking others on the course - this is learning from each other (peer mentoring) which we are VERY much in favour of. Understanding concepts by explaining them to each other is NOT the same as plagiarsm (= copying a solution). Tutorials are another good place to ask questions, or if you'd like to discuss in more depth then email me (chris.done@durham.ac.uk) - I aim to respond within 24 hours Mon-Fri (but probably will also respond on a similar timescale at weekends as well!)
