Sönke Johnsen - Five Way Interview

Originally trained in maths and art, Sönke Johnsen has studied optics in biology for the last 35 years, the last 24 of which have been at Duke University. He is particularly interested in vision and light in the open ocean, but has also worked on coastal, freshwater, and terrestrial species, animal navigation, vision at night, and human cataracts.  His field work mostly involves open-ocean research cruises that use SCUBA and deep-sea manned or robotic submersibles.  In addition to exploring the optical and visual tricks that animals perform, Johnsen is interested in improving communication between biologists and physicists, and scientists and artists. Johnsen’s research has been featured in many traditional media outlets, but also in Finding Nemo, The Magic Treehouse book series, NPR’s Radiolab, the poetry of John Updike, the humor of Dave Barry, and most recently in Ed Yong’s An Immense World. Johnsen has written or co-written five books, The Optics of Life, Visual Ecology, Into the Great Wide Ocean, Color in Nature, and The Radiant Sea. 

Why marine biology? 

Mostly because the North Carolina beach was my yearly escape into nature from highly industrial Pittsburgh. I became devoted to the ocean at a very early age. 

Why this book? 

A few reasons. First, I wanted to show people the open ocean world that I loved and that was so unfamiliar to most. Second, I wanted to give people an idea of what ocean research is actually like. Finally, I wanted people to understand how scientists think and see that they’re not so different from everyone else. 

Why do you think this is the least known habitat on earth?

Mostly because it is so hard to get to! To get out of sight of shore for days or weeks at a time, you need a large ship. And to do anything beyond looking over the side, you need a ship that allows you to explore the ocean via scuba diving, collecting animals with nets, or using small submarines. Very few people have ever done something like this. Even those that go on cruise ships for vacations are usually many dozens of feet above the water and can’t tell what’s going on underneath the surface.

What’s next?

My next research expedition will be on the RV Atlantis, which houses and operates the Alvin submersible. We will be going to the deep-sea hydrothermal vents off the Azores to study light and vision about a mile below the surface. 

What’s exciting you at the moment? 

So many things. The natural world is beautiful, fascinating, and often very funny. I suppose it’s odd for an author to say this, but I follow what I once saw written on the wall of the library in Woods Hole, Massachusetts –  'Study nature, not books'. 

These articles will always be free - but if you'd like to support my online work, consider buying a virtual coffee or taking out a membership:

The Antigravity Enigma - Andrew May ****

Antigravity - the ability to overcome the pull of gravity - has been a fantasy for thousands of years and subject to more scientific (if impractical) fictional representation since H. G. Wells came up with cavorite in The First Men in the Moon . But is it plausible scientifically?  Andrew May does a good job of pulling together three ways of looking at our love affair with antigravity (and the related concept of cancelling inertia) - in science fiction, in physics and in pseudoscience and crankery. As May points out, science fiction is an important starting point as the concept was deployed there well before we had a good enough understanding of gravity to make any sensible scientific stabs at the idea (even though, for instance, Michael Faraday did unsuccessfully experiment with a possible interaction between gravity and electromagnetism). We then get onto the science itself, noting the potential impact on any ideas of antigravity that come from the move from a Newtonian view of a...

The World as We Know It - Peter Dear ***

History professor Peter Dear gives us a detailed and reasoned coverage of the development of science as a concept from its origins as natural philosophy, covering the years from the eighteenth to the twentieth century. inclusive If that sounds a little dry, frankly, it is. But if you don't mind a very academic approach, it is certainly interesting. Obviously a major theme running through is the move from largely gentleman natural philosophers (with both implications of that word 'gentleman') to professional academic scientists. What started with clubs for relatively well off men with an interest, when universities did not stray far beyond what was included in mathematics (astronomy, for instance), would become a very different beast. The main scientific subjects that Dear covers are physics and biology - we get, for instance, a lot on the gradual move away from a purely mechanical views of physics - the reason Newton's 'action at a distance' gravity caused such ...

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...
