Science Quotes

From 600+ conversations with the world’s leading thinkers.

We are hard wired through our biology to understand: what there is, what to do about what there is, that there is a difference between knowing what there is and knowing what to do about what there is and what the difference is.

Surgery, like many other disciplines, is primarily about facts, your relationship with the facts, how you manage, handle, interpret and use those facts. This is something we all begin to do very early in life, in our childhood.

Music can help us heal and achieve therapeutic outcomes by tapping into various neurochemical circuits that influence mood and behaviour. Ours was the first lab to show that listening to music releases the brain's natural pain relievers—opioids. Relaxing music can modulate prolactin, a soothing, tranquilizing hormone. Music also releases dopamine which helps us to focus and motivates us to stay on task.

Our vision is something we call 'SETI of the mind.' The goal is to treat the DMT space and other altered states as novel domains to be explored, much in the same way we treat outer space. It is a completely new frontier inhabited by beings that we treat as potential intelligences with whom we can establish a two-way relationship.

During the day, we strive for efficiency. The brain forms habits to avoid wasting energy on unnecessary tasks, like finding a new route to work daily. It automates routes, like driving on autopilot, sometimes arriving home without recalling the journey. This efficiency undoubtedly has its benefits in a resource-limited environment shaped by evolutionary pressures.

Consciousness is any kind of subjective experience whatsoever. It's what goes away when you fall into a dreamless sleep or go into general anesthesia, and what comes back when you wake-up or come around.

Diversity brings interesting ideas, interesting challenges and creativity. If there are too many females in a field, then get more men! If there are too many men in a field, get more women!

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.

Dogs, chipmunks, squirrels, fish and dolphins do not have a meta-cognitive understanding of themselves. A dog can feel sad (we think) but cannot have a meta-cognitive understanding of the fact they feel sad and what to therefore do about.

It is difficult to imagine a graver threat; or an area of human endeavour or global ecology in which the profound consequences of runaway climate change would not be disastrous. Already, it is estimated that around 300,000 people die every year as a direct result of climate change.

The brain is definitely not doing computation in the purest sense. We are not crunching numbers in binary ones and zeros in our heads. When people ask me how our system compares to an NVIDIA GPU in terms of FLOPS, I tell them they're asking the wrong question. A more important question is: what are your inputs, what output do you want, and how intelligently can the system get from one to the other?

It's amazing how little data the world has about women and girls. There are even gender gaps in the data we use to measure gender gaps.
