“I find many adults are put off when young children pose scientific questions. Why is the Moon round? the children ask. Why is grass green? What is a dream? How deep can you dig a hole? When is the world's birthday? Why do we have toes? 

Too many teachers and parents answer with irritation or ridicule, or quickly move on to something else: 'What did you expect the Moon to be, square?' Children soon recognize that somehow this kind of question annoys the grown-ups. A few more experiences like it, and another child has been lost to science. Why adults should pretend to omniscience before 6-year-olds, I can't for the life of me understand. What's wrong with admitting that we don't know something? Is our self-esteem so fragile?”

My god, Octavia Butler, just miss ONCE
 Page from a book saying:

From EARTHSEED: THE BOOKS OF THE LIVING
Choose your Leaders with wisdom and forethought.
To be led by a coward is to be controlled
by all that the coward fears.
To be led by a fool is to be led
by the opportunists who control the fool.
To be led by a thief is to offer up your most precious treasures to be stolen.
To be led by a liar
is to ask to be told lies.
To be led by a tyrant is to sell yourself and those you love into slavery.

“No nation, no religion, no economic system, no body of knowledge, is likely to have all the answers for our survival. There must be many social systems that would work far better than any now in existence. In the scientific tradition, our task is to find them.” ― Carl Sagan

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.

A Reminder from Carl
“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.”

We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster.

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.

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.

“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.”

“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.”
