The Problems of Physics
A conversation with Sir Anthony Leggett

In 1987, the highly respected condensed matter physicist Tony Leggett penned The Problems of Physics, acutely highlighting the key foundational problems of the age. 26 years later we sit down with Professor Leggett, now a Nobel Laureate, to see what has changed and what has stayed the same.

The Gentleman Laureate (Commentary Excerpt)

The Nobel Prize has always vaguely irritated me. The idea that one’s entire research career might somehow be neatly defined by what a bunch of Swedes happen to find noteworthy has long struck me as arbitrary at best and, in my darker moments, a sad commentary on our need for self-affirmation.

Richard Feynman typically summed it up best when asked if his work on quantum electrodynamics fully merited being awarded the Prize: “I don’t know anything about the Nobel Prize and what’s worth what…I’ve already got the prize. The prize is the pleasure of finding the thing out, the kick of the discovery, the observation that other people use it. Those are the real things. The honors are unreal.”

On the other hand, it’s clear that these sorts of major prizes and awards have their uses. Life without the annual Nobel announcements, for example, would mean that the mainstream media would pay even less attention than usual to scientific discoveries, literary accomplishments or the enlightened few who are advancing the cause of global peace.

The Nobel Prize does one other very useful thing too: it provides a sort of academic bulletproofing for those who might wish to indulge in more general musings on the future of their field, speculations which are invariably great fun for the rest of us who might be unwilling or unable to follow technical arguments in detail.

Along with two others (Alexei Abrikosov and Vitaly Ginsburg), Tony Leggett won the Nobel Prize for physics in 2003 for “pioneering contributions to the theory of superconductors and superfluids” and is universally appreciated as that very rare bird indeed: an unequivocally brilliant and unreservedly decent person...
