We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and even a third electron, can be detached.
In such an environment, I was able to study things that could be of immediate usefulness to the world. That learning experience undoubtedly served me well when I eventually entered the work force.
I feel, sometimes, as the renaissance man must have felt in finding new riches at every point and in the certainty that unexplored areas of knowledge and experience await at every turn.
I don't think it ever works to tell people what they can't eat. They can do it for so long, and then they fall off. You have to bring them into a new relationship with food.
I like to eat good food. I cook and collect wine. I like going for long walks when I can.
Oh yes, after the war, and we were all starving - we had no proper food or anything - no proper shoes.
Great research universities must insist on independence from government and on the exercise of academic freedom.
I studied what principles under-laid peace and prosperity and concluded the only way to achieve societal well-being was through a system of economic freedom.
When the freedom they wished for most was freedom from responsibility, then Athens ceased to be free and was never free again.
The road to freedom lies not through mysteries or occult performances, but through the intelligent use of natural forces and laws.
No! on Human Rights and Freedom, on a subject that is as self-evident as that two and two make four, there is no need of any written authority.
The embattled gates to equal rights indeed opened up for modern women, but I sometimes think to myself; that is not what I meant by freedom, it is only social progress.
What makes revolutionary thought unique is its clarity and dignity, and its clear grasp of freedom and justice: simple, clear words that are understood without the need for any help from elite writers or thinkers.
For me, forgiveness and compassion are always linked: how do we hold people accountable for wrongdoing and yet at the same time remain in touch with their humanity enough to believe in their capacity to be transformed?
We are involved in youth testing internationally. We want to try to prove without a shadow of a doubt the relationship between physical fitness and health, not just physical fitness and ability to perform.
Successful technologies often begin as hobbies. Jacques Cousteau invented scuba diving because he enjoyed exploring caves. The Wright brothers invented flying as a relief from the monotony of their normal business of selling and repairing bicycles.
We had every problems starting a big top could have. The tent fell down on the first day. We had problems getting people into the shows. It was only with the courage and arrogance of youth that we survived.
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.
Once we started to urbanize, we put ourselves on this treadmill. We traded away stability for growth. And growth requires change.
Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise.
People are seeing the impact of climate change around them in extraordinary patterns of floods and droughts, wildfires, heatwaves and powerful storms.
