There are no uninteresting things, only uninterested people.
I've seen a lot of talks on a lot of specific topics, mostly climatological, at scientific conferences, but at the AGU's fall meeting this year was lucky to hear a talk in honor of a great scientist named John Tyndall given by the wonderfully eloquent and generous Kelly Redmond of the Desert Research Institute.
This talk included plenty of science, but ranged much more widely than most, and had not just fact to offer but also inspiration. It even touched the heart. While I'm trying to find out if the video version is readily available to the general public, as I think it should be, let me quote for Google's sake some of its highpoints, including an aphorism Redmond came across in high school, from G.K. Chesterton.
There are no uninteresting things, only uninterested people.
(Redmond actually improved it a little: Chesteron's original is a little more plodding.)
Words to live by — as an individual, a scientist, and a journalist. Here's Kelly. I'm a big fan.
