I am a mathematician. In fact, I have a Ph.D. in mathematics. But, I am terrible at arithmetic. Confused? I certainly would have been if a self-proclaimed mathematician told me that 15 years ago.

The answer to this riddle is simple: math is not numbers. Whenever a glimpse of my…

The fate of the universe rests in your hands, hero. We see it all the time — cosmic battles of good and evil being played out on screen or in video games. But this is science fiction — surely, without superpowers, that hero could never be you… or could it?


German Chancellor Dr. Angela Merkel calls it a “miracle of technology.” The device, an IBM Q System One, was recently unveiled as the most powerful quantum computer in Europe. …


My attempt to recreate John Wheeler’s illustration of a participatory universe.

Wheeler called it the Participatory Anthropic Principle. It goes something like this. The answers we get from posing questions to Nature depend very much on the questions we ask. Without any questions, nothing would be answered — hence we are participants in the bringing about of events. …

Quantum physics is weird. That’s what you’re supposed to think, anyway. But, also, it’s over one hundred years old and is the most accurate scientific theory ever created. Moreover, it provides the basis for all modern technology. Surely, then, someone understands what’s going on, right? …right?

I’ll let you decide…


A game of “Quantum” Tic-tac-toe.

In 1950, Bertie the Brain delighted crowds at the Canadian National Exhibition. It was the first known computer game with a visual display. It was a customed-made electronic version of Tic-tac-toe.

Now, I do.

Blankface.

I’m due…

Where Did the Universe Come From? and Other Cosmic Questions is a book I wrote with my academic colleague and friend Geraint Lewis. Geraint is a gifted scientific communicator and, if you aren’t already from Wales, you’ll love his Welsh accent. Geraint is also an astrophysicist, whereas I am a…


There are infinite versions of you living out every potentiality in a vast multiverse of parallel worlds

Or, so says the Many-Worlds Interpretation of quantum physics. The modern idea of the Many-Worlds Interpretation of quantum physics has been in the news recently, mostly due to a new popular book on…

I get a lot of emails from aspiring authors asking how I got started and what they should do to get their book or idea published. Unfortunately, every path to success is one of paid-off risks or just otherwise blind luck. …
