On January 10, 1992, the sea was awash with yellow ducks, blue tortoises, green frogs and red beavers. A container filled with 29,000 bath toys had fallen off a ship during a violent storm in the North Pacific, almost exactly halfway between Asia and America. Seven months later, hundreds of the rubber toys were deposited on the coast of Sitka, Alaska, not far away from where some 61,000 Nike sneakers had washed up after a similar accident at sea two years earlier. It then occurred to American o...

Global HR influencer Josh Bersin recently singled out graph databases as the basis for a new wave of HCM technology over the next 5-10 years. Neo4j’s Amy Holder examines the claim and considers some real-world examples.

Binance Smart Chains Musical Beats, Alleged Ethereum Copycat, Shuts Down Days After Launch Ethereum and Binance Smart Chain are at war, and we can already see the first casualties. Musical Beats was just one of many apparent copycats. In brief Several new BSC projects look extremely similar to Ethereum projects. Amid the recent rise of EthereumNFT project EulerBeats, an alleged copycat version, Musical Beats, launched on Monday on Binance Smart Chain (BSC).  Just days later, Musical Beats is s...

A Self-Taught Math Genius Wrote This Riddle While Serving Time in Prison. Can You Solve It? Evelyn Lamb © Kory Kennedy Self-taught student Chris Havens got his number theory riddle published in a mathematics magazine. Last year, Christopher Havens, an inmate serving to 25 years for murder, made headlines as the lead author on an academic paper published in Research in Number Theory. Havens had dropped out of high school, but discovered his fascination with mathematics shortl...

Our image of the day Space 16/02/2021 Space.com Staff © Provided by Space Valentine Island in northern Western Australia is a swirling mix of blues and reddish browns, as seen from space by the Copernicus Sentinel-2 mission. The mission, which is made up of two satellites, imaged the tiny island for Valentines Day. Valentine Island is just about 1 mile (1.60 kilometers) long and 0.15 miles (250 meters) wide and can be found in the King Sound, a large gu...

This recent snow storm was classified as "major" and affected a majority of the Northeast United States, with New York declaring a state of emergency for both the immense snowfall and blistering winds. Copernicus Sentinel-2 is an Ear...

Turbulence trouble Illustration of Jupiters Great Red Spot. Credit: Mark Garlick / Getty Images. “When I meet God,” physicist Werner Heisenberg allegedly once said, “I’m going to ask him two questions: why relativity? And why turbulence? I really believe he’ll have an answer for the first.” Although the quote is almost certainly fictional, it captures the sheer frustration many physicists feel about turbulence: the complex, chaotic, unpredictable flows in fluids. This phenomenon su...

Samuel Velasco/Quanta Magazine Interestingly, while Euler and Lhuilier imagined their polyhedra as solid, Euler’s formula is computed using only zero-dimensional vertices, one-dimensional edges and two-dimensional faces. So Euler’s number ( V – E + F) actually derives from the two-dimensional surface of the polyhedron. Today, we would imagine these shapes as hollow shells. Moreover, all that matters is the topology of the object. If we make a polyhedron out of clay, mark the ed...
