“I got out of the Navy because I stopped getting adrenaline in gunfights. That's when it gets dangerous. You don't want to get killed because you get bored. A bullet only needs to be right once.”

Former SEAL Team Six member who shot Osama bin Laden

When you close your eyes and imagine the person you're going to be in 10 years, this area of your brain is totally deactivated – it's treating the person you are going to become as a stranger. This is why people have such a hard time getting prostate exams, staying on a diet, quitting smoking, because the person who is going to benefit the most from these things is literally not you.

Author & Researcher on Flow State & Human Peak Performance

Anyone worth following in peak performance will tell you that 90% of human performance is mental. The understanding of that mental aspect of the game is brand-new – perhaps 10-20 years old. The work being done around the neuroscience of performance is creating an unprecedented rate of change; it's honestly off the charts.

Being at that altitude though – 100 miles higher than the space station, enables you to see even more of the planet's curvature – it's a different viewpoint, a different experience and perspective – you truly felt like you were interacting with the environment, you felt like a real spaceman – it was extraordinary.

Astronaut and educator who conducted spacewalks on the Hubble Space Telescope

One of the amazing things is how adaptable our brains our – and by day 2, I was feeling really good. NASA is pretty good at understanding how to keep you healthy in space; and so you go through sleep-shifts to help you stay rested, and to make sure you don't get a drop in performance from being tired.

I don't know why I didn't just walk-away from Los Alamos...

We are at a stage of development where we have 'god like' physical powers. In the bible, only God could create new life forms- yet with the genetics technologies we have, we can do that. In the Bible, only God was supposed to be able to throw down thunderbolts that could incinerate whole cities; we call them nuclear weapons.

Co-inventor of Public-Key Cryptography & Diffie-Hellman Key Exchange

I tried to remain as emotionless as possible – remaining as much of a scientist as I could be, going with the evidence. I felt that although I didn't have a coach on hand in Ireland, and even though the sport of MMA was very small, I had mountains of evidence I could study.

Knowledge isn't always used to make people better off, of course. It can be used to make more lethal weaponry and more effective militia and armies – so we must couple knowledge with humanism, with universal sympathy, for it to be a force for good. Without knowledge, however, all the sympathy in the world would be impotent – they must exist together.

— Steven Pinker

Cognitive Scientist & Psychologist Known for Research on Language and Human Nature

An appreciation of entropy is necessary to grasp that we are not entitled to wellbeing, progress, comfort, or health. The forces of the universe are- at best, indifferent- at worse, antipathetic- to our interests. Left to their own devices, things get worse.

Once we take their quantum property into account, space and time changes dramatically. Space is granular, because one of the characteristics of quantum theory is to show that continuous things have often a granular structure, like light, which is a cloud of photons. Similarly, time cannot be anymore understood ad an external independently flowing entity. Time is just he counting of granular happenings in nature.

— Carlo Rovelli

Theoretical physicist known for loop quantum gravity research and popular science writing

Quantum mechanics is the most radical break in our thinking of reality that we have ever encountered... Quantum mechanics comes along and says that whole experience is misleading, and that the best you can ever do is to predict the probabilities of outcomes. Quantum mechanics says our world is nebulous, fuzzy, a haze of possibilities until it somehow snaps to attention upon an appropriate interaction, observation or measurement.

— Brian Greene

Theoretical Physicist & Bestselling Author on String Theory & Cosmology

In the 1960s and 70s, a lot of quantum physicists (probably high on LSD) thought that quantum mechanics could explain the nature of consciousness, and phenomena like ESP. To this day, you have the Deepak Chopras of the world who associate quantum mechanics with spiritualism and all manner of pseudo-science from homeopathy to teleportation.

— Jim Al-Khalili

Theoretical physicist, author, and BBC science communicator known for public engagement

Quantum mechanics is a whole new way of thinking– it says that the world is all by itself as a wave function of the universe, but you can never observe that. You can never observe a wave function directly. There is a complex relationship between what the world is and what you see when you look at it, and that relationship involves the idea that you can never predict precisely what you will see, but you can simply say the probability of what you will see.

— Sean Carroll

Theoretical physicist & podcaster explaining cosmology and philosophy

I feel altogether confident that the historian of the future will estimate the past thirty years as the most extraordinary in the history of the world up to the present... there has been no period at all comparable with it unless it be the period about 300 years ago, which saw the development of Galilean and Newtonian mechanics. This was indeed of incalculable importance for the destinies of the race; the conceptions then introduced are not only the basis of modern material civilization, but they were the cause of a very complete change in man's whole intellectual and spiritual outlook- in his philosophy, his religion, and his morals.

Physicist who measured electron charge and discovered photoelectric effect

World poverty has been reduced significantly- and whilst everyone seems to think the world is getting more impoverished, this simply is not the case. Scientific cooperation has improved too, and this has allowed significant advances in global health.

Harvard Professor & Creator of "Soft Power" Concept

If I say to you 41, it's data. If I tell you 41 is the temperature in centigrade, that's information. If I tell you 41 is the temperature, in centigrade, of a human patient, that really is information – in fact, it's in danger of becoming knowledge because of the contextualisation it gives you.
