How The Turntable Paradox Works
Leave most objects on top of a turntable, and set it spinning, and they’ll fly off in short order. Do the same with a ball, though, and it somehow manages …read more Continue reading How The Turntable Paradox Works

Europe’s Energy Squeeze Pushes Large Hadron Collider To Halt Operations
Energy prices have been in the news more often than not lately, as has war. The two typically go together, as conflicts tend to impact on the supply and trade …read more Continue reading Europe’s Energy Squeeze Pushes Large Hadron Collider To Halt Operations
Iron Nitrides: Powerful Magnets Without the Rare Earth Elements
Since their relatively recent appearance on the commercial scene, rare-earth magnets have made quite a splash in the public imagination. The amount of magnetic energy packed into these tiny, shiny …read more Continue reading Iron Nitrides: Powerful Magnets Without the Rare Earth Elements
“Gigantic jet” lightning blasts record-breaking bolt upwards into space
While a thunderstorm can put on quite a show for spectators on the ground, the best bits often happen above the clouds. Scientists have now described in detail the most powerful “gigantic jet” of lightning ever observed, which blasted energy equivalent… Continue reading “Gigantic jet” lightning blasts record-breaking bolt upwards into space
What is gravitational lensing and how can the James Webb Telescope use it?
If you’ve seen the first images from the James Webb Space Telescope (JWST) this week (and let’s face it, how could you not?), you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help … Continue reading What is gravitational lensing and how can the James Webb Telescope use it?
Does Hot Water Freeze Faster Than Cold? Debate Continues Over The Mpemba Effect
Does hot water freeze faster than cold water? On its face this idea seems like it should be ridiculously simple to test, and even easier to intuit, but this question …read more Continue reading Does Hot Water Freeze Faster Than Cold? Debate Continues Over The Mpemba Effect
Hubble’s “magnum opus”: most precise measurement of universe’s expansion
NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.Continue Readi… Continue reading Hubble’s “magnum opus”: most precise measurement of universe’s expansion

World’s most powerful X-ray laser now fires a million bursts per second
The world’s most powerful X-ray laser is ready for operation after a massive overhaul. A powerful upgrade to Stanford’s Linac Coherent Light Source (LCLS), LCLS-II uses temperatures colder than deep space to accelerate electrons to near light-speed and… Continue reading World’s most powerful X-ray laser now fires a million bursts per second
Theory, Practice, and Ducted Fans
About a year ago, [Wyman’s Workshop] needed a fan. But not just a regular-old fan, no sir. A ducted fan. You know, those fancy fan designs where the stationary shroud …read more Continue reading Theory, Practice, and Ducted Fans
