Above, the four-day school week embraced by the 27J district outside Denver. Despite the shorter week’s popularity, researchers warn, it undermines learning when instructional time is reduced. By Vince Bielski, RealClearInvestigationsJuly 17, 2024 Next month, the Huntsville School District in Arkansas will join the wave of public schools switching to a four-day week. The shorter… Continue reading The 4-Day School Week: It’s a Trend Across America … Despite Questionable Results
How the Seven Bridges of Königsberg Spawned New Math
During the 18th century the denizens of the Prussian city of Königsberg wrestled with a puzzle: How could they find a walking path through the city that crossed each of its storied seven bridges exactly once? The bridges spanned a river containing two large islands. No matter how much they strategized their routes, they couldn’t… Continue reading How the Seven Bridges of Königsberg Spawned New Math
‘Sensational’ Proof Delivers New Insights Into Prime Numbers
Sometimes mathematicians try to tackle a problem head on, and sometimes they come at it sideways. That’s especially true when the mathematical stakes are high, as with the Riemann hypothesis, whose solution comes with a $1 million reward from the Clay Mathematics Institute. Its proof would give mathematicians much deeper certainty about how prime numbers… Continue reading ‘Sensational’ Proof Delivers New Insights Into Prime Numbers
People who had tiny plastic particles lodged in a key blood vessel were more likely to experience serious health problems or die during a three-year study
Microplastics Linked to Heart Attack, Stroke and Death People who had tiny plastic particles lodged in a key blood vessel were more likely to experience serious health problems or die during a three-year study By Max Kozlov & Nature magazine Khanchit Khirisutchalual/Getty Images Plastics are just about everywhere — food packaging, tyres, clothes, water pipes.… Continue reading People who had tiny plastic particles lodged in a key blood vessel were more likely to experience serious health problems or die during a three-year study
What Could Explain the Gallium Anomaly?
The gallium anomaly, however, would point toward a lighter-weight sterile neutrino, with the electron neutrinos emitted by the radioactive source sometimes oscillating into a sterile neutrino that wouldn’t interact with the gallium. In some models, lightweight sterile neutrinos could comprise a fraction of the universe’s dark matter, though not all of it because they would… Continue reading What Could Explain the Gallium Anomaly?
The School of Civic Leadership Looks to Protect the American Experiment
Etched onto the side of the Main Building at the University of Texas at Austin is a verse taken from John’s Gospel: “Ye shall know the truth and the truth shall make you free.” Justin Dyer says that this represents UT’s Austin’s North Star: “The university is a truth-seeking institution.” A faculty partner of the… Continue reading The School of Civic Leadership Looks to Protect the American Experiment

What Is Machine Learning? | Quanta Magazine
By now, many people think they know what machine learning is: You “feed” computers a bunch of “training data” so that they “learn” to do things without our having to specify exactly how. But computers aren’t dogs, data isn’t kibble, and that previous sentence has way too many air quotes. What does that stuff really… Continue reading What Is Machine Learning? | Quanta Magazine
Can President Biden Resist His Dark Money Allies?
Does President Biden have any ability to resist his dark money allies? That question was teed up when the U.S. Supreme Court recently asked for the Biden Department of Justice, through the Solicitor General, to state its views on whether the Supreme Court should take up a dark-money-funded public nuisance lawsuit out of Hawaii. The… Continue reading Can President Biden Resist His Dark Money Allies?
How America’s Fastest Swimmers Use Math to Win Gold
Except in my case, it really is a digital twin. It looks like an EKG, going tch, tch, tch, and it’s developed based on the data I’ve captured about an athlete’s movements. I can model how they will race under different conditions. Over the last seven or eight years, I’ve collected thousands of swims from… Continue reading How America’s Fastest Swimmers Use Math to Win Gold
