“Books are patient where we are slow to understand, allow us to go over the hard parts as many times as we wish, and are never critical of our lapses. Books are key to understanding the world and participating in a democratic society.”

Looking through one of the four windows of the Orion spacecraft, a tiny crescent Earth is illuminated against the blackness of space and grows smaller as the crew journeys closer to the Moon. Part of the window edge is visible; the rest is darkness. [Alt-text slightly revised from ESA/NASA version]

Hasn’t read or seen it, but this is why I fell in love with science.

I grew up a perfectionist, always afraid of being wrong. Then I learned that being wrong, in science, is just part of the process. It doesn’t matter if you’re wrong, and admitting it is the right thing to do.

Write them out anyway, because bad writing can usually be fixed through revision and practice. Most of writing well happens through practice. It's a skill as much as if not more than a talent. Most people could write decently well, given time and effort.

Trump wants you to believe he’s more powerful than he is - and that you have less power than you do.

Tomorrow, millions of Americans will gather to remind one another where power actually resides in this democracy: with us, the people.

“It is well within our power to destroy our civilization, and perhaps our species as well. If we capitulate to superstition, or greed, or stupidity, we can plunge our world into a darkness deeper than the time between the collapse of classical civilization and the Italian Renaissance. But we are also capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet, to enhance enormously our understanding of the universe and to carry us to the stars.”

“...Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives ... on a mote of dust suspended in a sunbeam...”

It was an honor and delight to see the Voyager Golden Record make it to a Pixar movie but this cowardly flattening of Elio is shameful.

“Many persons have inquired: Where is the goal of mankind? [...] Past thinking and methods did not prevent world wars. Future thinking must prevent wars. [...] A new type of thinking is essential if mankind is to survive and move toward higher levels.”

Red protest-style graphic with bold white text reading “Scientists Against ICE.” Below, rows of black human silhouettes stand holding hands. Centered is the Stand Up for Science logo, followed by text: “Calls for a General Strike Jan 23, 2026, Minnesota.” Black starburst shapes frame the sides. Bottom text reads: “Mobilize the fight for science and democracy.”

ICE’s actions tear families apart, intimidate communities, & undermine the conditions that make education, research, healthcare, & public trust possible.

We’re calling on scientists to join the general anti-ICE strike in Minnesota on January 23rd.

“The many sorrows of our recent history suggest that we humans have a learning disability. We might have thought that the horrors of World War II and the Holocaust were enough to inoculate us against the toxins there revealed and unleashed. But our resistance quickly fades. A new generation gladly abandons its critical and skeptical faculties. Old slogans and hatreds are dusted off. What was only recently muttered guiltily is now offered as political axiom and agenda. There are renewed appeals to ethnocentrism, xenophobia, homophobia, racism, sexism, and territoriality. And with a sigh of relief we are apt to surrender to the will of the alpha, or long for an alpha we can surrender to.”

"Human beings must involve themselves in the anguish of other human beings. This, I submit to you, is not a political thesis at all. It is simply an expression of what I would hope might be ultimately a simple humanity for humanity's sake."

“Even a casual scrutiny of history reveals that we humans have a sad tendency to make the same mistakes again and again. We're afraid of strangers or anybody who's a little different from us. When we get scared, we start pushing people around. We have readily accessible buttons that release powerful emotions when pressed. We can be manipulated into utter senselessness by clever politicians.

Give us the right kind of leader and, like the most suggestible subjects of the hypnotherapists we'll gladly do just about anything he wants — even things we know to be wrong. The framers of the Constitution were students of history. In recognition of the human condition, they sought to invent a means that would keep us free in spite of ourselves.”

The first time Charlie Chaplin spoke onscreen, he implored the people of the world to resist the rising tide of fascism.

Nearly 90 years later, it remains a timely message.

A shot of deep space, streaked by stray light beams inside the camera. In the middle of the right-hand sunbeam is a pale blue dot.

A shot of deep space, streaked by stray light beams inside the camera. In the middle of the right-hand sunbeam is a pale blue dot.

On 13 February 1990, from a distance of 6.4 billion km, NASA's Voyager 1 spacecraft turned around and photographed our homeworld.

About halfway up on the right side is a tiny speck of light, about one pixel across.

"That's home. That's us.

A mote of dust suspended in a sunbeam."
