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 […]
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 […]
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 […]
Understanding physics can be satisfying. Understanding physics some physicists don’t understand brings super-satisfaction. Many think they can’t understand physics. Seems to me that often it is physicists they can’t understand. I think anybody who can figure how to travel to another country can, with no more effort, understand a lot of physics. With two provisos: […]
Motion is smooth, as any eye can see. In 1738, Scottish philosopher David Hume could―with little chance of challenge―say: ‘The infinite divisibility of space implies that of time, as is evident from the nature of motion.’ But physics now knows that, at scales far smaller than an atom, space isn’t smooth and motion must […]
One of the neat things about the way the universe began is that it brings out principles that help to follow physics and philosophy that, without them, appear beyond reason. They simplify what lies behind some deep ideas, such as strings. String theories abound in many versions. They are based on fancy math. Their math […]
Man in motion (myself, not the Night Ranger album), I could get conflicted (once again): The universe moves on, I see this, yet I know it never moves. It has no way to move. It has no time. At any given now it simply is; so now is all it ever has. It is a […]
