Interview transcript

– Yes?

– Hello. My name’s Joanna Rose. I am making a recording for Nobelprize.org which is the official Website of the Nobel Foundation.

– Ah, that sounds important. However, I’m just about to leave for the airport; my driver is waiting downstairs. So this is not the way just now… I’m going to Berkeley, California.

– But this is just like three minutes …

– Okay, okay.

– I just want to congratulate you.

– Thank you very much.

– Did you expect it?

– Well, of course, one cannot expect something like that. I had a little spark of hope, I have to admit, though.

– Every year? Or this year?

– For a number of years.

– How many years?

– Oh …! But no, of course, when the news comes, it’s totally unexpected. And I’m still up in the clouds; I haven’t settled down yet.

– You’ll be in the plane …

– Right, right!

– What does it mean to you, to get the Prize?

– Well, I mean, it’s the ultimate recognition that scientists can hope to receive. It’s recognition not just for my person, but, I think, for our entire team, for the organisations that have supported our work. And I think for Germany it is certainly a sign that, hopefully, will attract more young people into science, because for a while it looked like we were out of luck with modern Nobel Prizes. Of course, in the early days, Germany did pretty well.

– Yes. Do you think that the Prize is just a reward, or can you …?

– Well, it depends on what one does with it. Certainly there will be more opportunities to give opinions outside my area of expertise. I will try to avoid that! And I will try to use it as a means to be able to continue our research, hopefully beyond my official retirement age in Germany.

– Is there any special field that you would like to …?

– Well, for me, the field of light, of lasers, of atoms, molecules, has been an unending series of surprises, and I can’t think of a better field. But I think we will, hopefully, find new things, in the future.

– How will you celebrate the Prize?

– Well, we’ve already celebrated in a rushed ceremony, because I have to leave for the airport and, as I said, the driver is waiting downstairs. So I am, just now, going on a trip to California. And maybe over there we will continue to celebrate in a circle of friends who are all gathering to honour Charlie Townes on his ninetieth birthday.

– Ah, I see. Thank you very much for this conversation.

– Okay. You’re welcome.

– Hope to see you in Stockholm. Bye-bye.

– Bye-bye.
