“In terms of weapons, the best disarmament tool so far is nuclear energy. We have been taking down the Russian warheads, turning it into electricity. 10 percent of American electricity comes from decommissioned warheads.” -Stewart Brand Arguably the greatest advance of humanity — and the cause of the greatest increase in our quality of life…

“There’s something about sitting alone in the dark that reminds you how big the world really is, and how far apart we all are. The stars look like they’re so close, you could reach out and touch them. But you can’t. Sometimes things look a lot closer than they are.” -Kami Garcia When we consider…

“The bedrock nature of space and time and the unification of cosmos and quantum are surely among science’s great ‘open frontiers.’ These are parts of the intellectual map where we’re still groping for the truth – where, in the fashion of ancient cartographers, we must still inscribe ‘here be dragons.’” –Martin Rees Inside the nuclear…

“The physicist is like someone who’s watching people playing chess and, after watching a few games, he may have worked out what the moves in the game are. But understanding the rules is just a trivial preliminary on the long route from being a novice to being a grand master. So even if we understand…

“Hurricane Katrina overwhelmed levees and exploded the conventional wisdom about a shared American prosperity, exposing a group of people so poor they didn’t have $50 for a bus ticket out of town. If we want to learn something from this disaster, the lesson ought to be: America’s poor deserve better than this.” -Michael Eric Dyson…

“We have to understand the ubiquity of energy in everything we do. Energy is core to our economy and it brings with it environmental challenges, and it’s core to our security challenges.” -Ernest Moniz In 1953, then-President Eisenhower, in the aftermath of World War II and with rising tensions between the USA and the Soviet…

“That’s a misconception, Lennie. The sky is everywhere, it begins at your feet.” -Jandy Nelson There are all sorts of explanations that people give for why the sky is blue. Some say that it’s because of the fact that oxygen is a light blue gas. Others contend that the sky reflects the blue ocean, giving…

“I’d rather fight 100 structure fires than a wildfire. With a structure fire you know where your flames are, but in the woods it can move anywhere; it can come right up behind you.” -Tom Watson On September 2nd, a group of teenagers were lighting fireworks in the Columbia Gorge near Eagle Creek. They would…

“The sun is a miasma Of incandescent plasma The sun’s not simply made out of gas No, no, no The sun is a quagmire It’s not made of fire Forget what you’ve been told in the past” -They Might Be Giants Ask anyone where the Sun (or any star) gets its energy from, and most…

“For although it is certainly true that quantitative measurements are of great importance, it is a grave error to suppose that the whole of experimental physics can be brought under this heading.” -Hendrik Casimir Ever since we first discovered that the expansion of the Universe is accelerating, scientists have puzzles as to what’s causing it.…
