Steven Weinberg - Four Way Interview

Steven Weinberg was educated at Cornell, Copenhagen, and Princeton, and taught at Columbia, Berkeley, M.I.T., and Harvard. In 1982 he moved to The University of Texas at Austin and founded its Theory Group. At Texas he holds the Josey Regental Chair of Science and is a member of the Physics and Astronomy Departments. His research has spanned a broad range of topics in quantum field theory, elementary particle physics, and cosmology, and has received numerous awards, including the Nobel Prize in Physics. His latest book is To Explain the World.

Why science?

I have known that I wanted to be a theoretical physicist since I was sixteen  It was irresistible to me to think that, by stewing over what is known experimentally in the light of present theories, and noodling around with equations, someone could come up with a new theory that turned out to make successful predictions about the real world.  That earlier successful theories like quantum mechanics and relativity were esoteric and counter-intuitive and used fancy mathematics only added to the challenge.

Why this book?

A while ago I decided that I needed to learn more about an earlier era of the history of science, when the goals and standards of physics and astronomy had not yet taken their present shape.  I became impressed with the many differences between the mentality of scientists before the seventeenth century and our own.  It was terribly difficult for them to learn what sort of thing can be learned about the world, and how to learn it.  I tried in this book to give the reader an idea of hard it has been to come to anything like modern science.

What’s next?

Cambridge University Press and I are nursing the second edition of my graduate-level treatise, “Lectures on Quantum Mechanics,” through to publication later this year.  I have added a lot of new material, and sharpened the arguments that lead to a controversial conclusion, that at present there is no really satisfactory interpretation of quantum mechanics.

What’s exciting you at the moment?

There are several experimental facilities that are now coming on line, and that we hope will make discoveries of fundamental importance.  One is the improved Large Hadron Collider, which is starting up again soon at higher energy, and may be able to discover signs of supersymmetry, and/or the dark matter particles that astronomers tell us make up 5/6 of the matter of the universe.  Another instrument is the Advanced Laser Interferometric Gravitational Wave Observatory, which will be completed soon and will have a good chance of observing gravitational waves produced by pairs of neutron stars as they coalesce.  That’s just two examples.

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...

The Infinite Alphabet - Cesar Hidalgo ****

Although taking a very new approach, this book by a physicist working in economics made me nostalgic for the business books of the 1980s. More on why in a moment, but Cesar Hidalgo sets out to explain how it is knowledge - how it is developed, how it is managed and forgotten - that makes the difference between success and failure. When I worked for a corporate in the 1980s I was very taken with Tom Peters' business books such of In Search of Excellence (with Robert Waterman), which described what made it possible for some companies to thrive and become huge while others failed. (It's interesting to look back to see a balance amongst the companies Peters thought were excellent, with successes such as Walmart and Intel, and failures such as Wang and Kodak.) In a similar way, Hidalgo uses case studies of successes and failures for both businesses and countries in making effective use of knowledge to drive economic success. When I read a Tom Peters book I was inspired and fired up...

The War on Science - Lawrence Krauss (Ed.) ****

At first glance this might appear to be yet another book on how to deal with climate change deniers and the like, such as How to Talk to a Science Denier.   It is, however, a much more significant book because it addresses the way that universities, government and pressure groups have attempted to undermine the scientific process. Conceptually I would give it five stars, but it's quite heavy going because it's a collection of around 18 essays by different academics, with many going over the same ground, so there is a lot of repetition. Even so, it's an important book. There are a few well-known names here - editor Lawrence Krauss, Richard Dawkins and Steven Pinker - but also a range of scientists (with a few philosophers) explaining how science is being damaged in academia by unscientific ideas. Many of the issues apply to other disciplines as well, but this is specifically about the impact on science, and particularly important there because of the damage it has been doing...
