David Linden – Four Way Interview

David J. Linden is professor of neuroscience at Johns Hopkins University School of Medicine in Maryland, USA. The author of more than ninety scientific papers and the acclaimed book The Accidental Mind, he also serves as editor-in-chief of the Journal of Neurophysiology. His latest book is Pleasure.

Why Science?

It was either that or crime and science seemed slightly less risky.

Why this book?

This book is about how the pleasure centers of the brain are activated by food, sex, meditation, exercise, drugs, gambling, paying taxes and goofing around on the Internet. It required a lot of fieldwork but I was prepared to make that sacrifice for my readers. Pleasure is the first book to explain the biology of reward in a way that will make you feel smarter and give you a laugh at the same time. Plus, it will provide you with clever anecdotes about topics from lesbian bonobo sex to the neuroscience of weight loss to hallucinogenic reindeer urine that will make you the toast of your social circle.

What’s next?

More fieldwork, I think.

What’s exciting you at the moment?

My lab has several new efforts that have me very enthused. These rely upon implanting cranial windows in the skulls of mice and then placing the mice under a special microscope (called a 2-photon confocal microscope) that allows us to see into the middle of otherwise opaque living brain tissue. This technique is allowing us to make time-lapse movies showing how neurons, glial cells and blood vessels in the brain respond to exercise and motor learning and how recovery of function proceeds following brain damage from amphetamine drugs.

Rakhat-Bi Abdyssagin Five Way Interview

Rakhat-Bi Abdyssagin (born in 1999) is a distinguished composer, concert pianist, music theorist and researcher. Three of his piano CDs have been released in Germany. He started his undergraduate degree at the age of 13 in Kazakhstan, and having completed three musical doctorates in prominent Italian music institutions at the age of 20, he has mastered advanced composition techniques. In 2024 he completed a PhD in music at the University of St Andrews / Royal Conservatoire of Scotland (researching timbre-texture co-ordinate in avant- garde music), and was awarded The Silver Medal of The Worshipful Company of Musicians, London. He has held visiting affiliations at the Universities of Oxford, Cambridge and UCL, and has been lecturing and giving talks internationally since the age of 13. His latest book is Quantum Mechanics and Avant Garde Music . What links quantum physics and avant-garde music? The entire book is devoted to this question. To put it briefly, there are many different link...

Should we question science?

I was surprised recently by something Simon Singh put on X about Sabine Hossenfelder. I have huge admiration for Simon, but I also have a lot of respect for Sabine. She has written two excellent books and has been helpful to me with a number of physics queries - she also had a really interesting blog, and has now become particularly successful with her science videos. This is where I'm afraid she lost me as audience, as I find video a very unsatisfactory medium to take in information - but I know it has mass appeal. This meant I was concerned by Simon's tweet (or whatever we are supposed to call posts on X) saying 'The Problem With Sabine Hossenfelder: if you are a fan of SH... then this is worth watching.' He was referencing a video from 'Professor Dave Explains' - I'm not familiar with Professor Dave (aka Dave Farina, who apparently isn't a professor, which is perhaps a bit unfortunate for someone calling out fakes), but his videos are popular and he...

Everything is Predictable - Tom Chivers *****

There's a stereotype of computer users: Mac users are creative and cool, while PC users are businesslike and unimaginative. Less well-known is that the world of statistics has an equivalent division. Bayesians are the Mac users of the stats world, where frequentists are the PC people. This book sets out to show why Bayesians are not just cool, but also mostly right. Tom Chivers does an excellent job of giving us some historical background, then dives into two key aspects of the use of statistics. These are in science, where the standard approach is frequentist and Bayes only creeps into a few specific applications, such as the accuracy of medical tests, and in decision theory where Bayes is dominant. If this all sounds very dry and unexciting, it's quite the reverse. I admit, I love probability and statistics, and I am something of a closet Bayesian*), but Chivers' light and entertaining style means that what could have been the mathematical equivalent of debating angels on...
