Ant-Man is back this week in a new sci-fi movie. Rumor says your favorite shrinking superhero’s set to shrink even smaller than before. This could set a trend. Will we soon see Ant-Man in action all the way down to Planck-scale? The sixties comics and the 2015 movie Ant-Man were about scale and a suit […]
Strange all this Difference should be ’Twixt Tweedle-dum and Tweedle-dee! — John Byrom (1692 – 1763) Twist and shout … Come on and work it on out — Phil Medley & Bert Berns (1961) Australian physicist Sundance Bilson-Thompson made a stunning discovery. He starts with a simple entity—a tiny twist. With the quirky humor that […]
Stephen Hawking’s final paper was published this week. Like his last book, The Grand Design, it is about how the universe began. In 1979, he became the seventeenth Lucasian Professor of Mathematics at Cambridge University. His modest aim was to understand the universe, the whole thing, from beginning to end. He missed his mark by […]
It all began so easily. Physics uses math so it was natural for physicists to look for math that is convenient. This led physics down a dead-end street. Fixing it could lead to a huge opportunity. The beginning goes back to the 1600s. Having revolutionized what would soon be called physics, Isaac Newton fell into […]
These are exciting times. Every few months astronomy surprises us with insights into ancient secrets. New telescopes are scanning galaxies throughout the visible universe. Most galaxies are mind-bogglingly far away. Exactly how far has long been a fundamental issue. But we just got a whole new way to measure it. Today the universe is much […]
In 1849, gold gave a kick start to the new State of California. Its non-native population grew 100-fold in a single year. Its miners soon took 300 tons of gold ($12 billion at today’s prices) from the ground. How did the gold get there? A few months ago, an extraordinary event—maybe the most widely studied […]
So much about Donald Trump, his behavior, his connections, his campaign and his presidency seems so crazy it is hard to make sense of it all—until we see for years he’s been a Russian agent working for spymaster Vladimir Putin. This is a deeper treason than previously speculated. We don’t know what is going on […]
Quantum gravity is all the rage in physics these days. There are books about it but none say what quantum gravity is. And none report real progress. We should be upset about this. Really! Quantum gravity tries to reconcile our two immensely successful—but mutually inconsistent—theories about the world: quantum theory and relativity. A quantum theory […]
He that breaks a thing to find out what it is has left the path of wisdom. – J.R.R. Tolkien Particle physics treats the electron as having zero size. But recently its size and even its shape have been the subject of serious investigations. They hinge on a simple but audacious question: If the electron […]
