We have the power of knowledge- for example to save the whales. The whales are obviously not going to save us. We need to have solidarity among humans, that the big problems we are facing, that affect all of humanity and we all equally have the responsibility to do something about it.

All conflicts are different with their particular history and reasons. I think that inequality within societies and between regions has become a key cause for conflict, exacerbated by rapid information dissemination, as people are (now) more aware of inequalities...

You have to get under the skin of every employee, becoming a chief meaning officer, giving your team purpose, getting everyone on the same page. You have to make sure your entire team knows where they're going, how they're going to get there, and what's in it for them.

Rather than politicising our cultural challenges, we have to allow people to feel comfortable about their culture and about who they are, and to accept each other as equals.

I've always felt negotiation is pretty-easy. You have to look at any situation from the perspective of all sides, and find a zone of fairness in between.

The easiest way to understand noise is by thinking about measurements. Suppose you are measuring a line with a very fine ruler. You will expect some variability such that you will not get the same number every time when you measure. That variability is noise. In the mathematics of accuracy, the expression for total error is very simple and quite compelling. It is bias-squared plus noise-squared. Bias and noise are both contributing to error and in that equation, they do so on the same basis.

Without what Becker called 'cultural world views' we would be overwhelmed by existential terror. Beliefs about reality that we share foster psychological equanimity by giving us a sense of meaning and value.

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.

I came away from space flight realising that I don't have enough faith to be an atheist. Life is so amazing. Even the simplest organisms have millions of cells that have to randomly align in a perfect way, and those processes are infinitesimally less complex than emotions and consciousness. When you look at the universe and the forces of nature – science has to explain how it all works, but to my mind, there just has to be a creator.

The change I'm most passionate about – because of the impact it's had on my own life – is creating a healthy transition to sleep that begins before you even step into your bedroom. I treat my own transition to sleep as a sacrosanct ritual. First, I turn off all my electronic devices and gently escort them out of my bedroom.

For many years, motorsport resembled a pyramid—a well-established, widely recognized structure with Formula 1 at its pinnacle. When Formula E emerged, it occupied a completely different position. It remains somewhat set apart, and only in recent years has it begun to be recognized as established motorsport by the broader community.

Read a lot. Never accept current standards. Always improve yourself. And remember, you always meet twice in life.
