After Albert Einstein published his special theory of relativity in 1905, he spent the next decade trying to come up with a theory of gravity. But for years, he kept running up against a problem. He wanted to show that gravity is really a warping of the geometry of space-time caused by the presence of… Continue reading The Geometric Tool That Solved Einstein’s Relativity Problem
The Webb Telescope Further Deepens the Biggest Controversy in Cosmology
But Freedman suspects that the Cepheid-based H0 measurement is not as trustworthy as the others. It is extremely sensitive to assumptions about, for example, the elemental composition of the Cepheids, and each star’s neighborhood. Dust in the galactic disks where Cepheids live can absorb their light and dim them. The Webb’s infrared vision pierces the… Continue reading The Webb Telescope Further Deepens the Biggest Controversy in Cosmology
Is Technology in the Olympics a Form of Doping or a Reality of Modern Sport?
Today’s Olympic Games are a technological marvel. Slow-motion cameras play back the milliseconds-long difference between first and second place. Wearable sensors detect clean hits in a bout of fencing or a round of tae kwon do. Olympic athletes use motion tracking, microcurrents and lactic acid monitors to improve form, speed up recovery and prevent injuries.… Continue reading Is Technology in the Olympics a Form of Doping or a Reality of Modern Sport?
Are Robots About to Level Up?
Within just a few years, artificial intelligence systems that sometimes seem to display almost human characteristics have gone from science fiction to apps on your phone. But there’s another AI-influenced frontier that is developing rapidly and remains untamed: robotics. Can the technologies that have helped computers get smarter now bring similar improvements to the robots… Continue reading Are Robots About to Level Up?
The Viral Paleontologist Who Unearths Pathogens’ Deep Histories
You aren’t worried about catching a virus from your samples? Not at all. Everything inside is dead. Every biological process has been disrupted by formalin. This is why the preparation is so amenable to preserving viral RNA: You put a complete stop to every enzymatic process, including the degradation of RNA. But humans carry respiratory… Continue reading The Viral Paleontologist Who Unearths Pathogens’ Deep Histories

The IRA’s Two-Year Disastrous Anniversary
As we mark the two-year anniversary of the Inflation Reduction Act (IRA), it’s hard to pinpoint what exactly has been reduced. Inflation continues to strain American families by an extra $1,000 per month, and the burden of government regulation on businesses has certainly not eased, as they struggle under new tax rates, mandates, and rising supply costs.… Continue reading The IRA’s Two-Year Disastrous Anniversary

How Does Math Keep Secrets?
Can you keep a secret? Modern techniques for maintaining the confidentiality of information are based on mathematical problems that are inherently too difficult for anyone to solve without the right hints. Yet what does that mean when quantum computers capable of solving many problems astronomically faster are on the horizon? In this episode, host Janna… Continue reading How Does Math Keep Secrets?
