Dancing To His Own Tune (David Politzer)

It took a bit of time to get David Politzer to agree to sit down and talk with me. A co-recipient of the 2004 Nobel Prize in Physics, he was all too familiar with people approaching him out of the sheer excitement at being able to tell their friends that they had spent some time chatting with a Nobel Laureate.

That wasn’t my problem. By a curious twist of fate, over the years I had found myself spending enough time in the company of Nobel Laureates to know that it could often be a highly overrated experience. Indeed, other than a few notable exceptions (such as the almost overwhelmingly genial Tony Leggett), knowing that someone had a Nobel Prize invariably made me look searchingly towards the nearest exit.

Still, it was David’s Nobel that first brought him to my attention, as it were. Years ago an astute colleague urged me to read The Dilemma of Attribution, David’s clever, thoughtful, and humble Nobel lecture that detailed the communal nature of frontline scientific inquiry: using his own “Nobel-winning” work on asymptotic freedom to explicitly demonstrate how science builds shining edifices of our understanding by rigorously compiling insights by different researchers, one upon the other.

Telling It Like It Is (Paul Steinhardt)


Paul Steinhardt in conversation with Howard Burton

One of the greatest challenges for teachers of science and mathematics, it is often declared, is finding ways of attracting young people to their vitally important subjects.

All too often this results in skeptical students being bombarded with an uninspiring mix of obvious propaganda (Science is fun!), appeals to self-interest (Mathematics is the key to unlocking doors to a successful career!), and a bit of social guilt thrown in for good measure (A background in science is essential for grappling with the next generation of societal issues!).

Unsurprisingly, such tactics don’t tend to work very well. The very nature of fun is that it is inherently self-evident: trying to convince people that something is fun is very much like trying to convince them that their healthy vegetables are also great-tasting. (more…)

Information Loss (Roger Penrose)


Roger Penrose in conversation with Howard Burton

You might think that a blog post about Roger Penrose that’s called “Information Loss” would necessarily involve black holes, entropy, and Hawking radiation, perhaps also touching on bets over encyclopedias and all that.

Not this time. Instead, I’d like to talk about a more everyday sort of information problem: how best to communicate science. I’ve been puzzling about this issue for as long as I can remember: first as a keen undergraduate anxious to share the sorts of things I was learning, and later as a physics graduate student trying to describe the essentials of my tiny corner of understanding to anyone who might listen. I always had a lingering sense of frustration that, somehow, I was unable to coherently capture the fundamental aspects of what attracted me, and what frustrated me, about physics. But I thought it was just me.

Years later, when I found myself running Perimeter Institute, I tried again: taking advantage of our robust scientific visitor program to put together a series of monthly public lectures of internationally renowned physicists. (more…)
