Ladies and gents, meet Prof. Peter Lawrence! One of the best prof I’ve ever had at school.
And the picture you are looking at now is taken today from his office. I asked him to give me a copy of a formula sheet which was handed out last week in class. He searched his office for this paper and after 10min when he couldn’t find that, he started to write that down again for me!(No wonder why he wasn’t able to find it)
