We need a New Year’s Revolution. (No typo: Revolution with a v.) Last week I suggested that the Large Hadron Collider may find no superparticles and that this could lead to a big change in physics. Indeed a common theme in last year’s posts was the need to complete the Physics Revolution that began a […]
Sounds like a The Big Bang Theory episode. Maybe someday it will be. But even in the fields of physics, supersymmetry is esoteric. What is it? What is its calamity? Why should you care? What it is is an idea: Particular superheroes! Here’s their story. The Standard Model is the crown jewel of physics. It […]
So, nat’ralists observe, a flea Hath smaller fleas that on him prey, And these have smaller still to bite ’em And so proceed ad infinitum. Jonathan Swift (1733) Once upon a time the world had a conversation about an idea called the atom. Greek philosopher Democritus kicked off the conversation around 400 BCE, saying matter’s […]
The idea of the universe as a single thing has roots in ancient societies. It speaks to our existential questions: Where are we? What is our relation to the world? In the fifth century BCE, Zeno of Elea ponders whether the world is one thing or many. He says the concept of plurality is a […]
Sir Isaac Newton was a serious two timer long before that term took on its modern meaning. In 1687 he spoke of two kinds of time: Absolute, true, and mathematical time, of itself, and from its own nature flows equably without relation to anything external, and by another name is called duration; [and] relative, apparent […]
Last week’s post looked at how physics turned its back on time. It had consequences. Today, leading physicists speak of time in despairing terms. Some propose to abandon it. Though buried deep in science journals, this situation eats at the roots of our economy. Is time lost beyond recall? Let’s recap: In 1905 Albert Einstein […]
Time matters to us all. We are defined by time. Mostly we don’t think about it. But it’s easier to think about than you might expect. Time became important in the 15th century. It came to be synonymous with clocks. Accurate chronometers would help sailors figure where they were at sea. Many made bold voyages—or […]
These days―thanks to the mash-up of Leonard Hofstadter, Sheldon Cooper, David Saltzberg, Ed Robertson and the Barenaked Ladies―most everyone has heard of the Big Bang theory. And most everyone knows it ‘all started with the Big Bang!’ Most everyone is wrong. Wikipedia has it precisely right. It says: The Big Bang theory is the prevailing […]
Tweedledum and Tweedledee Agreed to have a battle! Lewis Carroll (1871) ‘Our rock,’ we call it. Its tons of granite became solid some two billion years ago. Most recently―maybe ten thousand years ago―a glacier left it on the shoreline of a lake. On July 6 the spider shows up on our rock. She keeps to […]
