The DNA of the Universe

The universe burst into existence some 13,799,000,000 years ago. Why did it become this universe? Why does it have quarks and electrons; and elements including carbon, hydrogen, nitrogen and oxygen; and gravity to grow galaxies; and planets orbiting vast numbers of stars; and all of the ingredients that lead to life? Doing this required many […]

Taking Lessons from the Universe

Arithmetic is fundamental to science; but we tend to take it for granted. Few realize its foundations are shaky. Now there are exciting ways to firm them up. We are sold a knowledge pyramid like this: Sciences rest on a foundation of physics; physics on math; math on arithmetic. And arithmetic on logic— but, actually, […]

The Laws of Physics Are Not Sacrosanct

We like to think of laws of physics as fundamental, as properties of the universe. Actually, not. They are our inventions, tales we tell ourselves in terms of concepts we construct. They are good statistical approximations. But they don’t tell us what’s really going on. The real world is happening at Planck scale, named for […]

Is Our World Analog or Digital

We need new physics; and new physics needs new math. It won’t be easy but it is a huge opportunity. More than a hundred years ago physics chose to assume the universe is analog. It is now becoming clear that this is wrong: our universe is digital. We took a wrong turn that is having […]

One Hundred Years Old – A Bit Weird

It’s a season for something personal, another kind of time travel, a different kind of history. Here is a guest blog authored by my father, Don, a short sketch of his long life so far (he skips over his M.Sc. and careers in science and management). It is based on an article he published in […]

Avogadro and the Eaters of the Dead

We can find fundamental physics while meditating in unlikely places. My wife’s father had a fishing camp on a small island in a lake. He died when she was young. His remains lie in a village cemetery by a sandy track amid boreal forest. It is a lovely place. We visit it from time to […]
