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 […]
Twin mysteries arose around 1937 when Italian theoretical physicist Ettore Majorana suggested neutrinos are their own antiparticles. Soon afterward he took the night ferry from Palermo to Napoli and vanished, leaving us to ask: What happened to him; and was he right? The Standard Model has a place for every known elementary particle. It says […]
Albert Einstein introduced the photon to the world more than 100 years ago. Though physicists doubted—even ridiculed—his idea for years, it set off a scientific revolution. The photon now underpins foundations of the world economy. Yet to this day it is a mystery. Even when we know a photon has gone from A to B […]
Emergence is the source of all the laws of physics. Strange spots called fairy circles illustrate the way emergence brings new fundamental properties into the world, including space and matter. There are millions of them. Bare patches in grasslands, remarkably well-defined, regular in shape and spacing, and ordered in a roughly-hexagonal array over long distances, […]
Planck-scale physics is not yet in its infancy. It is in gestation. Arranging a successful birth requires a strategic discipline. Walk before you try to run! For some reason (we will get to that) physicists seem doomed to run. Indeed—to milk the metaphor for maybe more than it is worth—they essay hundred-meter sprints before they […]
It has long been a deep and frustrating puzzle. The charge on the electron, symbol e, is said to be an elementary quantum. That is, neither the electron nor its charge is ever seen to be subdivided. Lots of measurements reveal the charge on every electron has exactly the same value. For more than a […]
As Chubby Checker sang and showed a 1960s generation, “Let’s do the twist.” Twist is not only an important thing. It is the only thing. Look around; all that you can see is made of twist. How so? The explanation starts with atoms and takes us through topology and Solitaire to the final fate of […]
Of all questions the most fundamental is: What was the initial condition of the universe? It is fundamental for philosophy and religion. It is even more fundamental for physics. Unfortunately it is a realm where physics fears to tread. Yet we may need to tread this realm to find the much-sought Theory of Everything or […]
