Sabine Hossenfelder - Five Way Interview

Image © Joerg Steinmetz
Sabine Hossenfelder grew up in Frankfurt, Germany. She has a PhD in physics and is presently a Research Fellow at the Frankfurt Institute for Advanced Studies. Her current work is mostly in the foundation of physics. She has written over 80 research papers on topics ranging from quantum gravity to particle physics, cosmology, astrophysics, statistical mechanics, and quantum foundations. 

Sabine is creator of the popular YouTube channel Science without the gobbledygook. Her first book Lost in Math was published by Basic Books in June 2018. Her writing has been published, amongst others, in Scientific American, New Scientist, The Guardian, Aeon, Nautilus, and the New York Times. Her latest book is Existential Physics: A Scientist's Guide to Life's Biggest Questions.

Why Science?

Because I’m a curious person and science constantly teaches me new things. 

Why this book?

Physics taught us some deep lessons about the nature of time and reality and the limits of science that I think physicists don’t talk about enough. I wanted to tell people what we have learned, but also tell them where physics crosses over into pure speculation. So my book basically demarks the boundary between physics and religion and philosophy.

Why is the distinction between unscientific and ascientific important?

It’s like the distinction between atheist and agnostic. An atheist does not believe that god exists, an agnostic has no opinion about whether god exists or not – it’s a neutral position. We call something unscientific when it does not follow scientific methodology. By ascientific I mean something that science says nothing about. For example, planning your day based on what the horoscope says is unscientific. The idea that other universes exist that we cannot interact with is ascientific. Science can’t tell us whether they exist, but it also can’t tell us that they don’t exist. It’s not unscientific to believe in those other universes.

The distinction matters to me because ascientific ideas I think should have a place in our lives, and brains, and hearts. They should not be thrown out with those ideas that go against science just because our vocabulary doesn’t distinguish the two. 

What's next?

I am planning to have a weekly “Science News” show on my YouTube channel “Science Without the Gobbledygook”. As you can probably guess, I spend a lot of time reading science news, but not everyone has the time. So, once a week, I want to summarize the biggest science news for busy people, and hopefully have some interesting conversations about them! We’ll start this in a 10 week trial in early October. 

What's exciting you at the moment?

Like all astrophysicists, I am excited about the results from the Webb telescope. The data from early galaxies could really shake things up, and finally convince the community that the dark matter hypothesis has severe shortcomings.

God: the Science, the Evidence - Michel-Yves Bolloré and Olivier Bonnassies ***

This is, to say the least, an oddity, but a fascinating one. A translation of a French bestseller, it aims to put forward an examination of the scientific evidence for the existence of a deity… and various other things, as this is a very oddly structured book (more on that in a moment). In The God Delusion , Richard Dawkins suggested that we should treat the existence of God as a scientific claim, which is exactly what the authors do reasonably well in the main part of the book. They argue that three pieces of scientific evidence in particular are supportive of the existence of a (generic) creator of the universe. These are that the universe had a beginning, the fine tuning of natural constants and the unlikeliness of life.  To support their evidence, Bolloré and Bonnassies give a reasonable introduction to thermodynamics and cosmology. They suggest that the expected heat death of the universe implies a beginning (for good thermodynamic reasons), and rightly give the impression tha...

Humble Pi - Matt Parker ****

Matt Parker had me thoroughly enjoying this collection of situations where maths and numbers go wrong in everyday life. I think the book's title is a little weak - 'Humble Pi' doesn't really convey what it's about, but that subtitle 'a comedy of maths errors' is far more informative. With his delightful conversational style, honed in his stand-up maths shows, it feels as if Parker is a friend down the pub, relating the story of some technical disaster driven by maths and computing, or regaling us with a numerical cock-up. These range from the spectacular - wobbling and collapsing bridges, for example - to the small but beautifully formed, such as Excel's rounding errors. Sometimes it's Parker's little asides that are particularly attractive. I loved his rant on why phone numbers aren't numbers at all (would it be meaningful for someone to ask you what half your phone number is?). We discover the trials and tribulations of getting cal...

Quantum 2.0 - Paul Davies ****

Unlike the general theory of relativity or cosmology, quantum physics is an aspect of physics that has had a huge impact on everyday lives, particularly through the deployment of electronics, but also, for example, where superconductivity has led to practical applications. But when Paul Davies is talking about version 2.0, he is specifically describing quantum information, where quantum particles and systems are used in information technology. This obviously includes quantum computers, but Davies also brings in, for example, the potential for quantum AI technology. Quantum computers have been discussed for decades - algorithms had already been written for them as early as the 1990s - but it's only now that they are starting to become usable devices, not at the personal level but in servers. In his usual approachable style, Davies gives us four chapters bringing us up to speed on quantum basics, but then brings in quantum computing. After this we don't get solid quantum informat...
