Biden Must Repair—and Reinvigorate—Tech Diplomacy

The Trump administration did no favors with respect to the diplomats responsible for digital issues; it cut the State Department’s overall budget, minimized the importance of its technology work, and pulled the rug out from underneath those working in areas like free internet access and 5G supply chain policy.

How Much Energy Does It Take to Blow Up a Planet?

This position is measured in pixels, but we can convert it to distance by scaling it to a known object in the scene.But if I only plot its pixel position, I’ll underestimate the distance traveled and thus the speed.

I’d do the same thing for the vertical position to show that it's a parabola associated with constant downward acceleration.Here’s what I get:This is the trajectory for the whole thing, including the end where he bounces off the hay bale and flips over.

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.

Mandalorian vs. TIE Fighter: Who Would Win?

It's fairly linear, which means the TIE fighter is moving at a roughly steady speed of 117.3 meters per second (262 mph for the Imperials).He's already up to his maximum vertical speed by the time he gets 10 meters off the ground.

When Mueller ultimately concluded that any bad actions President Donald Trump may have taken could only be handled by impeachment , he was saying that the game must continue: A corrupt political system should correct itself.

Why Republicans Storming a SCIF Puts National Security at Risk

Why Republicans Storming a SCIF Puts National Security at Risk

But that's exactly what a group of Republican congressmen proudly did Wednesday morning.“BREAKING,” representative Matt Gaetz (R–Florida) tweeted at 11:32 am, “I led over 30 of my colleagues into the SCIF where Adam Schiff is holding secret impeachment depositions.” Schiff is the head of the House Intelligence Committee, who has led the recent inquiry into President Trump’s Ukraine imbroglio .

Could an Astronaut Lost in Space Use Gravity to Get Around?

Could an Astronaut Lost in Space Use Gravity to Get Around?

As part of my introductory physics course, students have to create a numerical calculation to solve a problem.So we can simplify the math by chopping the process up into short time intervals and assuming a fixed force within each increment.

Devin Nunes and the Power of Keyword Signaling

Devin Nunes and the Power of Keyword Signaling

His argument was similar to his remarks during a June 12 House Intelligence Committee hearing, where he referred to the Mueller Report as a “shoddy political hit piece” created through a “perfect feedback loop” between intelligence leakers, key intelligence figures, Democrats, and the media who perpetuate “fake outrage.” These remarks do more than assert his position.

Let's Break Down the Physics of a Wickedly Curving Baseball

This change in momentum of the air produces a force on the ball in the other direction. The magnitude of the force depends on the velocity, the angular velocity, the area of the ball, the density of air and a Magnus coefficient (CM).

Quantum Darwinism Could Explain What Makes Reality Real

Quantum Darwinism Could Explain What Makes Reality Real

One of the most remarkable ideas in this theoretical framework is that the definite properties of objects that we associate with classical physics—position and speed, say—are selected from a menu of quantum possibilities in a process loosely analogous to natural selection in evolution: The properties that survive are in some sense the “fittest.” As in natural selection, the survivors are those that make the most copies of themselves.

The Incredible Tech Behind This Year's Tour de France Bikes

The Incredible Tech Behind This Year's Tour de France Bikes

Pro riders will use the aero bike in races such as the Tour de France for longer, flatter stages as results show that an aero bike can be up to four minutes faster over a flat 40-km course (if riding conditions are favorable) as well as in sprint stages where the aerodynamic shape and uncompromising stiffness is an asset in getting you over the line in first place.

Quantum Computers Could Be True Randomness Generators

Quantum Computers Could Be True Randomness Generators

In our case, to randomly output a 50-bit string, you can build a quantum circuit that puts 50 qubits, taken together, into a superposition of states that captures the distribution you’d like to re-create.

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.

Post-Apocalyptic Survival Skills: How to Measure Acceleration

Post-Apocalyptic Survival Skills: How to Measure Acceleration

With that, I can find a force-acceleration equation for both masses. With an accelerating mass, the net force is NOT zero. Notice that if the two masses have the same value, the acceleration would be zero meters per second squared (that's good).

The Physics of the Millennium Falcon's Jump to Hyperspace

The Physics of the Millennium Falcon's Jump to Hyperspace

To estimate the acceleration, we can look at the angular size of the back of the Falcon as it moves away. All I need to do is measure the position of the sides of the Falcon and use that to calculate the angular size in each frame of the video during the jump to hyperspace.

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.

Spotify's Apple Complaint Cuts to a Core Antitrust Issue

If Spotify were to pay Apple's commission, he says, it "would force us to artificially inflate the price of our Premium membership well above the price of Apple Music." That's important because antitrust law in the United States places a major emphasis on how competition affects consumer pricing.

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.
