Ada Yonath

Anyone who sits in our jails who is not just a criminal but what we call a terrorist, with or without blood on his hands - and these definitions are also unclear to me - should not be sitting in our custody.

People always talk about the implication and applications of a process, but for me, the goal is purely about knowledge. Knowledge can become practical today, in 20 years, or in 500 years. Ask Newton. He didn't know there would be space research based on his accident with the apple.

No one ever said learning was to be easy, but it's part of the process of evolving as a human being, and we all have to go through it. When I look back, I see that each difficult time brought an important lesson. And I prefer to look at it with gratitude because I wouldn't be who I am today if I haven't gone through it all.
