If the ball hits the stick and bounces back, what will happen to the stick? If you said the stick will recoil to the right, you’re correct. We can think of this as a collision. When two objects collide, they exert forces on each other. And per Newton, the forces are equal and opposite, keeping…
This is a non-exhaustative list of places microplastics have been found: Mount Everest, the Mariana Trench, Antarctic snow, clouds, plankton, turtles, whales, cattle, birds, tap water, beer, salt, human plancentas, semen, breast milk, feces, testicles, livers, brains, arteries, and blood. My blood, specifically. In early March I milked a few drops out of my fingertips…
This story originally appeared on Grist and is part of the Climate Desk collaboration. Cities looking to eliminate fossil fuels in buildings have notched a decisive court victory. Last week, a federal judge dismissed a lawsuit brought by plumbing and building trade groups against a New York City ban on natural gas in new buildings….
Utada: What are you most focused on pursuing at the moment? Kojima: There is a theory in particle physics called the Standard Model, but it can only explain about 5 percent of the mass and energy in the universe. In fact, it is thought that about 26 percent of the mass and energy in the…
The unevenness of the state of each cloud layer is thought to be the reason why the brightness of SIMP 0136 changes as it rotates. It’s easy to understand if you think of Jupiter, which as a gas giant planet likely has a similar structure and chemical composition. Or for another way to picture this,…

An oil tanker carrying jet fuel was recently hit by a cargo ship while at anchor 13 miles off the east coast of England. This set off a series of large explosions and a huge plume of black smoke, while a still unknown…
So the UK government signed two partnerships: one with BioNTech to provide 10,000 patients with access to personalized cancer treatments by 2030, and a 10-year investment with Moderna in an innovation and technology center with capacity to produce up to 250 million vaccines. The stars were aligned. During the pandemic, the UK was opening clinical…
I expected to meet a dreaded “man-eater,” but when I saw it, I realized that it was a defenseless animal, more afraid of me than I was of it. That moment aroused my curiosity, and I decided to learn more about sharks. I travelled to the island of Guadalupe off the Pacific coast of Mexico…
In other words, Hilbert’s 10th problem is undecidable. Mathematicians hoped to follow the same approach to prove the extended, rings-of-integers version of the problem—but they hit a snag. Gumming Up the Works The useful correspondence between Turing machines and Diophantine equations falls apart when the equations are allowed to have non-integer solutions. For instance, consider…
Danielle Fugere, president and chief counsel for the shareholder advocacy nonprofit As You Sow, said disclosure is a prerequisite for holding banks to their climate goals. ”We want to understand what it is they’re doing,” she said. Laws like California’s bring to light the financial instability wrought by fossil-fuel-driven climate change and—in theory, at least—discourage financing…
