Scientists, environmentalists, and anyone who lives within a hundred miles of the winding Mississippi River will tell you—have told you, repeatedly, for 150 years—that efforts to tame the river have only made it more feral. But scientists would like more than intuition, more than a history of 18th-century river level gauges and discharge stations, more…
So you've decided you need a break from your smartphone. You're not looking to do anything drastic, like revert to one of those old school Nokia bricks, because, let's face it, having a supercomputer in your pocket comes in handy. But you've grown wary of how you use the thing—the way it keeps you up…
I don't know very much about bobsleds—but I know quite a bit about physics. Here is my very brief summary of the bobsled event in the winter Olympics. Some humans get in a sled. The sled goes down an incline that is covered in ice. The humans need to do two things: push really fast…
Attendance at this weekend’s March for Science is expected to be lower than last year's, when hundreds of thousands of people took to the streets across the country to protest the Trump administration and its science policies. Many anti-Trump protesters say their attention is now focused on other forms of action, such as filing lawsuits…
Maybe you have watched Stranger Things but maybe you haven't. I've seen it, and I thought it was great—and not just because there's lots of science in it. Don't worry, I'm not going to talk about multiple universes or quantum tunneling. Instead I am going to talk about salt. Small spoiler alert (but not really…
Every week science journalists get a bunch of emails from various Respectable Scientific Journals telling us, in advance, what articles those journals are going to publish. When I started in this game, these tables of contents came by fax; today, in the future, they're downloadable PDFs. The quo for all this quid is that we…
In early 2016, two planetary scientists declared that a ghost planet is hiding in the depths of the solar system, well beyond the orbit of Pluto. Their claim, which they made based on the curious orbits of distant icy worlds, quickly sparked a race to find this so-called Planet Nine—a planet that is estimated to…
Florida’s space coast roared to life on Tuesday as SpaceX fired off its long-in-development Falcon Heavy rocket from Kennedy Space Center. Tens of thousands of spectators made the pilgrimage from across the country to experience the immense heat and thunderous roar of the rocket’s 5 million pounds of thrust. Upon liftoff, at precisely 3:45 pm…
In the unfolding family separation crisis at the US-Mexico border, one thing has become increasingly clear; the federal government lacks any real plan for reuniting children with their parents. On Wednesday, President Trump signed an executive order that would keep children and their parents together, though in indefinite detention. But the administration’s “zero-tolerance” policy reversal…
I have a problem: I can't stop analyzing Star Wars movies. On top of that, there is another issue. I've stated that the physics of a movie doesn't have to be absolutely correct—and I still believe that. And now, I am going to complain about some physics in Star Wars: The Last Jedi even though…
