Scientists get first look at rocks causing slow moving quakes

Two International Ocean Discovery Program (IODP) expeditions to the Hikurangi subduction zone off the east coast of the North Island, undertaken in 2017 and 2018, mark the first time scientists from around the world had studied and directly sampled rocks from the source region of slow slip events using ocean floor scientific drilling methods.

A Tiny Glass Bead Goes as Still as Nature Allows

A Tiny Glass Bead Goes as Still as Nature Allows

It is as still as it could possibly be, as permitted by the laws of physics: It’s reached what physicists call the bead’s “motional ground state.” “The ground state is the limit where you cannot extract any more energy from an object,” says Aspelmeyer, who works at the University of Vienna.

How Much Superpower Does It Take to Bash a Bullet in Midair?

I can use a stationary object like the wall behind Wonder Woman as a reference point, but it’s only an approximation, since the wall is farther away.

A Kung Fu Master’s Leap Breaks the Internet—but Not Physics

Yep, once he pushes off the ground, his center of mass actually follows a normal parabolic trajectory.Usually when I do video analysis to track the motion of something through space, I graph vertical position in each frame as a function of time.

Super Planetary-Motion Smackdown: Kepler v. Newton

Super Planetary-Motion Smackdown: Kepler v. Newton

The ancient Greeks studied the earth and the sky, but their basic model had all the objects (sun, moon, and planets) moving in circles around us.Is there a more fundamental model that could explain both the motion of a planet orbiting the sun and the motion of the moon orbiting Earth?

The Biomechanical Perfection of Simone Biles in Flight

And then, pow pow, Biles is in the air, a möbius loop of motion 10 feet off the ground at the apex, more than a second in the air, twisting around her head-to-toe axis three times and flipping over her side-to-side axis twice before, bang!

Should You Buy the Nintendo Switch Lite?

You should also keep in mind that since the Lite won't include two detachable controllers right out of the box like the standard Switch does, the cost of making co-op happen will be higher than the initial $200 price suggests.

Physicists Hack the Uncertainty Principle to See an Ion Wiggle

As the ion bounces around the chip, they reduce the uncertainty in the ion’s position by periodically hitting it with an electric field. These electric fields, if real, would push a magnesium ion ever so slightly, so their chip could be further developed to sense these dark matter particles.

In Automation, the Last Motion Will Come Before the Last Mile

If we want to see robots create economy-scale effects in the short term, we should skip the “last mile” and look to what I call the “last motion.” These are the short task sequences between previously automated streams of work in highly structured environments, where humans currently handle various uncertainties involving physical inputs, control actions, and outputs.
