We asked each of our scientists to give us their thoughts on their professions and what they think the future holds for humanity.

What would you recommend for students wanting to pursue a similar career?
My advice to students is that they should always follow their passions and their convictions. The advice of well-meaning adults does not always take these crucial ingredients into account.

What do you like best about your profession?
First and foremost, I like science. It is exciting, absorbing and satisfying. And it engages me in rewarding interactions with students and colleagues. I wouldn’t change my profession for anything.

What makes you most fearful for the future?
I fear that complete nuclear disarmament will not become a fact until after the next nuclear war.

What makes you most hopeful for the future?
I was elated last year by a little-noticed bit of news: more than 50% of the Earth’s population now lives in countries where the fertility rate of women is at or below the replacement level.
