The Biomechanical Perfection of Simone Biles in Flight

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!

Finally, a Robot That Moves Kind of Like a Tongue

Two stickers with fibers running lengthwise constrain the balloon to make it turn as it inflates (such an actuator could also use hydraulics instead of air, by the way), while a third sticker with fibers running at a 45 degree angle make the balloon twist at the end.

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.

How to Shoot Stellar Slow-Motion Video on Your Phone

Many phones let you record HD video (1080p) at even higher frame rates: 240 fps slo-mo has become pretty common among premium devices, like the Pixel 3, the OnePlus 7 Pro, and the Galaxy S9.

This Jellyfish Robot Is Much More Than Just a Good Swimmer

This Jellyfish Robot Is Much More Than Just a Good Swimmer

At less than a quarter inch across, the magnetically activated robot mimics the entrancing locomotion of a jellyfish and uses the resulting disruption of water flow to manipulate objects, or to burrow to camouflage itself.

Physicists Hack the Uncertainty Principle to See an Ion Wiggle

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.

Depth of Field: At the French Open, Serena Williams Is a Study in Motion

Depth of Field: At the French Open, Serena Williams Is a Study in Motion. Serena Williams descended upon the clay courts of the French Open in Paris this week, where, the year prior, she had become a lodestar of ridiculous controversy.

A Physics Analysis of Every Jedi Jump in All of Star Wars

A Physics Analysis of Every Jedi Jump in All of Star Wars. For these Jedi jumps in Star Wars, it's plausible to estimate the distance scale by looking at things like Ewan McGregor (height of 1.78 meters) or Liam Neeson (height of 1.93 meters).

"You get to see things from a scientific perspective that you wouldn't normally get to see normally," says Daniel Gruchy, one half of the duo better known as YouTube's The Slow Mo Guys.

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

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.

The Odd Physics of Rey's Backflip in Star Wars: Episode IX

The Odd Physics of Rey's Backflip in Star Wars: Episode IX

For Rey jumping over (I assume she makes it) a TIE fighter, I'm just going to look at her vertical motion. There is some type of TIE fighter zooming toward Rey. You would think her goal is to jump over the spacecraft, but who really knows.

5 of the Best Demos of Projectile Motion and Its Quirks

5 of the Best Demos of Projectile Motion and Its Quirks

Both balls start with the same vertical position and the same vertical velocity (zero m/s) so that they have the same motion in the vertical direction and hit the ground at the same time. The water will shoot out horizontally, just like projectile motion.

Microsoft Employees Protest Treatment of Women to CEO Nadella

Microsoft Employees Protest Treatment of Women to CEO Nadella

The protesters asked Nadella to address claims of discrimination against women in promotion and advancement, as well as claims of sexual harassment, raised as part of a widespread discussion that has been building steam on internal company forums for the past two weeks.

Elon Musk’s Latest Tweets Land Him in Yet More Trouble

Elon Musk’s Latest Tweets Land Him in Yet More Trouble

That’s the thrust of a SEC action taken late Monday, when the US securities watchdog requested a federal judge hold Tesla CEO Elon Musk in contempt of court for a short series of tweets he posted last week.

Launch an 80,000-Pound Sled off an Aircraft Carrier? Sure!

Launch an 80,000-Pound Sled off an Aircraft Carrier? Sure!

Since the sled is launched horizontally, the starting vertical velocity is zero meters per second. If I had the height of the flight deck, I could use that and the vertical motion to find the time it takes to hit the water.

A Crocodile-Like Robot Helps Solve a 300-Million-Year Mystery

But today, in an epically multidisciplinary paper in Nature , researchers detail how they married paleontology, biomechanics, computer simulations, live animal demonstrations, and even an Orobates robot to determine that the ancient critter probably walked in a far more advanced way than was previously believed possible.

How to Calculate the Physics in Super Smash Bros. Ultimate

Here is the rule that I have for a jumping Captain Falcon: Yes, that seems like a crazy model, but when I run it I get the following plot (along with data from the video analysis).

Aquaman's Insane Leap out of Water Has One Foot in Reality

Aquaman's Insane Leap out of Water Has One Foot in Reality

It is this scene that I will analyze.Aquaman might be able to swim super fast, but once he leaves the water and enters the air there is only one force acting on him—the gravitational force that pulls straight down.

How to Deconstruct a Football Tackle With Physics

This says that the total force on an object (or football player) is equal to the rate of change of momentum. I can find that Thompson force by looking at his change in momentum in that same time interval.

Beep! Bloop! Buzz! Why Do UX Designers Often Neglect Sound?

But the cognitive and emotional effect is greater than you think.We partnered with Sentient Decision Science, a behavioral science research firm, to quantify this relationship using Implicit Association Testing, an online experiment that scientifically measures the strength of an individual’s associations between concepts and emotions.In this study, we assessed the strength of association between 20 different sounds and the emotion they inspired: 10 naturally occurring sounds—from a bird singing to squealing brakes—and 10 "designed" sounds created for products and experiences, like a microwave, a severe weather alert, and streaming TV sounds.

Bump-Canceling Bunk Beds Promise Supersmooth Bus Rides

Someday, it could even be more soothing than sleeping in, say, a house.“We can isolate a passenger’s body, and input frequencies that help people relax and fall asleep” in the same way that a hammock or rocking chair can help people chill out, Currier says.Cabin used off-the-shelf components, like a cheap Raspberry Pi computer and the electric motor from a hoverboard scooter, to move the bed up and down quickly enough to cancel out the lumps and thumps in the road.
