All my mind was centred on my studies. I divided my time between courses, experimental work, and study in the library. In the evening I worked in my room, sometimes very late into the night. All that I saw and learned was a new delight for me. It was like a new world open to me, the world of science which I was at last permitted to know in all liberty.
