Physics beat out chemistry to become the Senior Science in the second physics revolution starting around 1900. A hundred years ago this revolution held huge promise. Now historians of science call it the Unfinished Revolution. What went wrong? It is a strange but, in the end, illuminating five-part story. Part One: In 1851 mathematician Bernhard […]

Smashing Science
He that breaks a thing to find out what it is has left the path of wisdom. So says J.R.R. Tolkien’s hero-wizard, Gandalf, to Saruman (an anti-hero wizard). More than a century of successful atom smashing seems to say that Gandalf got this wrong. But let’s take a closer look at what we have—and what we […]
Lessons from Lost Worlds
In The Singular Universe and the Reality of Time Brazilian philosopher, Roberto Unger, and American physicist, Lee Smolin, team up to bring unruly mathematics and fanciful multiverses under control. They seek a renaissance of natural philosophy—ideas—as a driver of future physics. Let’s swing along with them. Central to their thesis is the idea of the […]
Ideas Live!
Philosophy involves the study of ideas. Yet some (like Stephen Hawking) say philosophy is dead. Others (such as Neil deGrasse Tyson) say philosophy may be alive but its ideas have no use in physics. Both of these exemplars hold the degree of Doctor of Philosophy so they should know. But so do I and I […]
Go Jets Go!
How about those jets! Jets in space are hot in science news these days. They are hot because they are a huge problem. How huge? Try thinking of a billion times a billion miles. Let’s start small. Archerfish find breakfast using water jets. Their jets are longer than their body size. How they shoot their […]
A Small Problem
In recent posts we’ve touched upon the sorry state of physics. ‘Sorry state’ is not just my view; many physicists and science writers see this the same way. Physics has now all but lost experimental contact with the real world. What went wrong? How can we fix it? And why should we care? What went […]
Fairy Tales and Physics
These days we all have a stake in physics. It’s not just that physics costs and we, the public, pay. Physics drives our economy. We should be concerned when physicists start writing about how badly it is going. When they write books about this, we should worry. It’s almost a decade since American physicist Lee […]
Going Up?
It is ‘an engineering project on a gargantuan scale.’ So says American physicist, P.K. Aravind. ‘By far the largest megaproject ever undertaken,’ says another American physicist, Adam Brown. Each is writing of an antigravity device called a space elevator. The picture shows how it’s supposed to work. The centrifugal pull of a counterweight holds up […]
Debt Stream
It is, or should be, of concern to every author to acknowledge other people’s contributions to their work. In my writing I try to extend such recognition not only to those I quote but also to those who in some manner influence my thoughts. It seems to me this gives the reader better insight into […]
