I have been very lucky to have won the Nobel Prize twice, It is, of course, very exciting

to have such an important【C1】______of my work. but the real pleasure was in the work itself.

Scientific research is like an exploraion of a voyage of discovery. You are【C2】______trying out new things that have not been done before. Many of them will lead【C3】______and you have to try something different, but sometimes an experment does【C4】______and tells you something new and that it is really exciting,【C5】______small the new finding may be. it is great to think “I am the only person who knows this” and then you will have the fun of thinking what this finding will【C6】______and of deciding what will be the【C7】______experiment.

One of the best things about scientific research is that you are always doing something different and it is, never【C8】______.There are good times when things go well and bad times when they【C9】______ . Some people get discouraged at the difficult times. but when I have a failure my policy has always been not to worry but to start planning the next experiment,【C10】______is always fun.
