The Conversation

We're sending this weekly newsletter a day later than usual because of a scheduling problem. Apologies for the mix-up. 

Welcome to the best of The Conversation U.S. Here are a few of our recently published stories:

As we all know, young children ask the best questions. They’re still learning about the world and are thus not saddled with assumptions. And their innocence makes them naturally curious. Often their queries stump even the smartest parents, and so we at The Conversation created a series that gets experts to answer some of these simple-seeming questions with often-complicated answers.

Our latest question, from 7-year-old Joshua, is: “How do atoms form?”

That would certainly stump me – and in fact it still stumps, to a much lesser degree, physicists like Stephen L. Levy of Binghamton University, State University of New York.

“Understanding how atoms form is a fundamental and important question, since they make up everything with mass,” Levy writes in one of last week’s most popular stories. But he acknowledges that experts in his field still “only have good guesses” to explain how it happens.

But he does his best and describes their good guesses about atoms, how they form and where they come from.

If you have a child with a burning question that you can’t answer – or if you’re a curious kid yourself – let us know and we’ll try to find an expert to answer your question. You can send your question to CuriousKidsUS@theconversation.com. Please tell us the child’s name and age and the city where you live.

And since curiosity has no age limit – adults, let us know what you’re wondering, too. We won’t be able to answer every question, but we will do our best.
