Dan Levitt - Five Way Interview

Dan Levitt spent over 25 years writing, producing and directing award-winning documentaries for National Geographic, Discovery, Science, History, HHMI (Howard Hughes Medical Institute).  He has filmed with Stephen Hawking, Michio Kaku, Bernard Carr, and Sean B. Carroll among many others. His latest book is What's Gotten Into You?

Why science?

I’ve always been drawn to the beauty of science. It offers me a way to appreciate the natural world and the fantastic physical, chemical, and biological web we’re part of. I think my sense of that deepened when I lived for a few years near a game park in Kenya. There was a small rainforest close by and everywhere I walked I had a view of Mount Kilimanjaro. It gave me a visceral sense of how enmeshed we are in a much larger ecosystem. Of course, science also helps us understand things that would otherwise be inexplicable, like the question at the heart of this book—how did we end up here?

Why this book?

The inspiration came when I realized that I really didn’t know what my body was made of, much less where that stuff ultimately came from. Once I realized that every particle within me sprang out of the Big Bang, I was hooked. I began wondering what happened— how did particles that were zipping around 13.8 billion years ago end up creating us?

At the same time, I began wondering how we are able to peer back billions of years in time. How did we do that? Those were the questions that started me off and I just kept thinking about them until I decided I would write the book.

In researching this book, what did you find most surprising?

I had never realized that life itself profoundly influenced our planet’s geology. Once photosynthesizing cyanobacteria came along, they began releasing oxygen that transformed Earth and made it possible for more complex cells and creatures to evolve.

I didn’t know some scientists suspect that the first life on Earth might have been microbes that hitched a ride on meteorites from Mars.

Something else that surprised me was how often scientists were initially dismissive of theories that we now recognize were groundbreaking. After finishing the first draft of my book, I circled back to try to understand why and I saw that cognitive biases had cropped up again and again. I ended up giving them nicknames, like the 'Too Weird to be True' bias and the 'As an Expert, I’ve Lost Sight of How Much Is Still Unknown' bias. I hadn’t expected to be thinking about cognitive biases at all.

What’s next?

First a really good vacation. Then I’ll be writing another book about scientific discovery. I haven’t settled on the topic yet, but I had a great time writing What’s Gotten Into You. It led me to think about so many things that I hadn’t expected to, so I’m looking forward to the next one.

What’s exciting you at the moment?

I’ve been listening to War and Peace on audiobook and loving it. Tolstoy is a master at making you feel like you’re present in the scene. I’ve also been playing with ChatGPT a bit and trying to understand what it will be capable of. At this point I can tell you that it’s a long way off from writing like Tolstoy.

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

The Infinity Machine - Sebastian Mallaby ****

It's very quickly clear that Sebastian Mallaby is a huge Demis Hassabis fan - writing about the only child prodigy and teen genius ever who was also a nice, rounded personality. After a few chapters, though, things settle down (I'm reminded of Douglas Adams' description of the Hitchhiker's Guide to the Galaxy ) and we get a good, solid trip through the journey that gave us DeepMind, their AlphaGo and AlphaFold programs, the sudden explosion of competition on the AI front and thoughts on artificial general intelligence. Although Mallaby does occasionally still go into fan mode - reading this you would think that AlphaFold had successfully perfectly predicted the structure of every protein, where it is usually not sufficiently accurate for its results to have direct practical application - we get a real feel for the way this relatively unusual company was swiftly and successfully developed away from Silicon Valley. It's readable and gives an important understanding of...

Nanotechnology - Rahul Rao ****

There was a time when nanotechnology was both going to transform the world and wipe us out - a similar position to our view of AI today. On the positive transformation side there was K. Eric Drexler's visions in the 1986 Engines of Creation. Arguably as much science fiction as engineering possibilities, it predicted the ability to use vast armies of assemblers to put objects together from individual atoms.  On the negative side was the vision of grey goo, out of control nanotechnology consuming all in its path as it made more and more copies of itself. In 2003, for instance, the then Prince Charles made the headlines  when newspapers reported ‘The prince has raised the spectre of the “grey goo” catastrophe in which sub-microscopic machines designed to share intelligence and replicate themselves take over and devour the planet.’ These days the expectations have been eased down a notch or two. Where nanotechnology has succeeded, it has been with the likes of atom-thick mat...
