You can't build a bridge or an aircraft using postmodernist feminist epistemology.

Our knowledge of the world is always fragmentary and incomplete and our explanations of how the world works have therefore to be considered as provisional. This means we have to accept that sometimes we will turn out afterwards to have been wrong.

Former UK Security and Intelligence Coordinator & National Security Adviser

In comparing alternative explanations, it is not necessarily the one with the most evidence apparently in its favour that we should choose but the one with least evidence against it. One solid piece of evidence can demolish a hypothesis.

If you don't believe in climate change, it is like telling me you don't believe in gravity. I don't care if you don't believe in gravity and I don't care if you don't believe in climate change… both are affecting you, and there's nothing you can do to deny or neutralize either of them.

Former UN Climate Change Executive Secretary & Global Climate Action Leader

Music is woven into the fabric of the universe. As far back as Pythagoras and Kepler, scientists were writing about the fact that music was intrinsic in the planets… part of the harmonic series in sound. Music is built into our neurology, our survival instincts and our communication.

British-Indian composer and musician known for world music and film scores

The scientist mindset says, I will not let my ideas become an ideology. When I start to form an opinion, I should treat it as a hypothesis before doing some observations or experiments to test it. I should be just as excited to find out I was wrong as to prove I am right.

We're outnumbered by bacteria 1.3:1, we're slightly more bacteria than we are human. We're also stardust. We are also 60% water, and that water in our bodies is billions of years old. At an atomic level, 98% of the hydrogen in our bodies came from the bigbang. We're incredibly ancient beings, perhaps we should see ourselves as aliens!

Our senses allow us to perceive, but they're incredibly limited. Science sees far beyond our human blind spots, and the reaches of this 'bubble' our senses create for us. When you're in a bubble, you inhabit a form of fictional reality, and we've seen the dangerous consequences of this in financial bubbles, stock market bubbles, real estate bubbles.

There's so much data that's been collected around fitness, but a lot of this has been based on male subjects and isn't always right to apply to women. Having been through the journey myself, I want to help more women become body-literate and motivated to enjoy exercise.

Space is a pretty scary place. Here on Earth, we're surrounded by nature and a nice blue sky. You don't realise that 16km above you, things start to go black…. 100km it's an inhospitable vacuum that will kill you in less than 60 seconds. Think how far we've come as humanity- we're a living species who have managed to escape our own planet.

British Astronaut & ISS Expedition Commander

As far as we know, space goes on for infinity, and yet is expanding at an ever-increasing rate. What is out there? We only understand about 5% of the universe, the rest is made-up of dark energy, dark matter and things we've yet to fully understand. Space triggers that innate curiosity in us about what's out there, where we came from, and the possibilities those answers could bring.

Loneliness is thought to be as bad for our health as smoking 15 cigarettes per day. If you're lonely, you have a 32% higher chance of getting a stroke, a 29% higher chance of having heart disease and 30% higher chance of dying prematurely.

Economist & Author on Globalization, Corporate Power & Digital Society

I remember being on a spacewalk and had a few seconds to see a view that humans were not meant to see. It was like I was hearing from God. But then, I had to get back to work.

NASA Astronaut & International Space Station Commander

The perspective of seeing the Earth from space has rewired our brain. We used to have a 2-dimensional view for hundreds of thousands of years. Now with space telescopes we have a 4-dimensional view of our universe.

I came away from space flight realising that I don't have enough faith to be an atheist. Life is so amazing. When you look at the universe and the forces of nature, there just has to be a creator.

NASA Astronaut & International Space Station Commander

Nothing prepares you to actually see the Earth from space. I spent more than 7 months in space, and even on my last day that view never got old.
