The quantum universe is counter-intuitive, it's fuzzy, probabilistic, and suggests things that we would regard as fantastical and magical if we saw them on the everyday scale- yet it's the most powerful theory in science.

It turns out that for every ipod sold by Apple, it makes the US trade deficit go up by USD 150. Is the US poorer because the world loves ipods? No, we accrue the high-value elements like intellectual property, profit, and so forth, and outsource the lower-value parts of the chain.

In my case, and for many people I know, a European identity is something that was denied to us for 50 years. For 50 years, Estonia was occupied by the Soviets, and so- for us- for our people, who were under communist domination, we were comfortable and happy to take on a European identity when we gained independence.

Extremism is the desire to enforce illiberal views which are in a dichotomy to the liberal values that we all adhere to in a Liberal secular democracy; and you can have non-violent or violent extremism.

Humans often come together by believing in ideas that may only exist in our imaginations. We have an ability to imagine together, to merge our ideas as a collective, which can slowly move us toward a future once believed to be impossible. This is part of what changes us from being simple animals to a group that will soon travel to Mars and perhaps even further. To me that is magic.

From a global point of view, we are currently in the middle of a technical revolution similar to what our grandparents experienced when everybody switched their horse carts for cars. The same is happening now and it is a phase of transition for many businesses.

The key both in the US and the UK is to have hand-raisers – people who want to take a chance, and get involved. That is a spirit that you see both in the UK and in America.

I'd never even heard the word 'entrepreneur' growing up – I didn't know what that meant. If I go back to my grandfather – he was the real entrepreneur. He developed things… he made spiked running shoes when he was only 15 (in 1895!).

Instead of looking at hoarded cash as being a 'rainy day fund' we need to view these balances as stores of economic growth. This cash represents potential investments, new jobs, new innovations and the potential for significant wealth creation and diffusion.

The people of the world are gambling for colossal stakes. Two centuries of scientific enquiry, founded in basic physics and powerful evidence, indicate that the risks from a changing climate over the next hundred years and beyond are immense.

When I sense stress, I allot three minutes to fully immerse myself in it. Many individuals attempt to escape stress, but evasion often amplifies it. It's akin to instructing someone not to think of pink elephants; the very command makes it impossible not to.

Women perform two-thirds of all labour and produce more than half of the world's food. Yet, women own only about one percent of the world's assets, and represent 70 percent of those living in absolute poverty.
