Climate Change is something which I’ve spent a lot of time on. I would highly recommend a book by Tim Flannery called The Weather Makers , which was one of the books that opened my eyes to the problem that we have in the world. I’m just reading Homo Deus , and I will carry on to read Sapiens , one of his first books. I just love the style of his writing. I love books where you’re learning something from them, rather than if I want fiction, I’ll get a good film out. If I’m reading books, I like to read books which have got some substance.

Yeah. Every year, I read The Old Man and the Sea by Hemingway.

I think a lot of them will probably be in the cooking space. Definitely On Food and Cooking . I’ve gifted that a lot. My career starts with that book in many ways. There wouldn’t be any of this modern cooking movement without Harold’s book, I don’t think. There certainly wouldn’t be modernist cuisine that played a big role in my career without that book. So I’ve gifted that a lot because I think it’s relevant and I think for a certain type of individual, it’s the kind of book that every time you open it up, you see something. You’re like, “I didn’t even know that was there; that’s super cool.” And you read something and go, “The world is way more interesting than I thought.” I think I’ve gifted Michel Bras’s Essential Cuisine quite a bit, although it’s hard to do now because I think it’s out of print in English and quite expensive. The other book I found myself gifting a lot lately is an out-of-print book on thermodynamics called The Second Law . It was written by an Oxford physical chemistry professor named P.W. Atkins. That book is just a phenomenal, casual, infographic-laden read on how the world works from an energy perspective. I found that so incredibly useful in trying to understand how to do something, how to make something work, whether something’s even possible. It’s frequently my bullshit detector. When somebody’s trying to convince me some technology or some idea has merit, I very quickly come back to just sketching out the kind of thing I did for that email, where it’s like, let me just see – with knowing nothing about the subject, if I can just sketch out the basic ideas of how much energy is going to be involved or consumed or if I assume limitless capacities, does this make any sense ever? So many things sound good, but just don’t pass muster as soon as you start looking at the world that way. You’re like, “Well, that’s clearly just a waste of everybody’s time and we should just stop and go do this thing over here,” which at least you’re not having to invent new physics or violate the laws of physics to go do it.
