Time is an oddity. In mystic thought, it is often cyclical. In classical Newtonian physics it was thought of as a steady march onward. In Einstein’s universe, it is wrapped up with the fabric of spacetime and can dilate in unexpected ways.
One thing we know about time is that it waits for no one. Time marches on (although not in a steady way, thanks to Einstein) and we experience it passively. Without any effort on our part, future becomes present and recedes into the past, even while we sleep. We can’t feel the passing of time like we feel the wind against our face, although change is happening imperceptibly, and after a lifetime, we realize that its passing has ravaged our fragile bodies.
Where did the time go, we ask? As if it is a thing that moves. Continue reading
I was sent a free copy of this book by the author, and asked to write an honest review. As the author noted in his email to me, ‘I think we have quite a few interests in common. ‘That’s very true, so I thought my review might also be of interest to my blog readers.
The book is the story of why the author (DJ MacLennan), has chosen to have his brain cryogenically frozen when he dies – or as he puts it – when current medicine can do no more to save him from death. It’s a personal story, and a scientific and philosophical investigation of what it means to live and die. Here’s my review of the book. Continue reading

My all-time favourite scientist was Isaac Newton. Newton was very clever. In fact he was a genius. He discovered lots of interesting and important things. Unfortunately, most of them turned out to be wrong. That doesn’t make him a bad scientist, of course. Finding wrong answers is an important way that science makes progress.
One of the reasons we know that Newton was a genius is that it took a very long time before anyone proved that he was wrong. Around 200 years, in fact. Then Albert Einstein (my second favourite scientist) showed that Newton was wrong, by coming up with some better explanations. Continue reading
Indulge me in a little thought experiment. Imagine a rocky planet a long way from here, orbiting a star rather similar to our own sun, at just the right distance for water to remain liquid. Let this planet have an atmosphere containing all the elements needed for interesting biochemistry to take place – carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur and so on. Now imagine that on this planet lives a single lifeform – one composed of trillions of tiny plant-like organisms amassed in one huge layer that covers the entire planet. This lifeform quietly converts the sun’s energy into food, and while it does so, it thinks. What kinds of thoughts might it ponder? Continue reading
I wrote recently about how one of the valuable functions that religion fulfils is that it offers a powerful motivational force. If we believe that God (or luck, or some other supernatural notion) is on our side, then we are empowered to fearlessly take on life’s challenges. Continue reading
I used to play in a den in the lane behind my house. It wasn’t really a den. It was just a space beneath a tree. But I made it my den. Continue reading
My debut novel, The Yoga Sutras, was published one year ago today. Publishing the book was a huge personal achievement for me, but it’s hardly been a bestseller. In order to punish myself for this failure and engage in some self-flagellation, I’ve decided to take a hard look at reviews of the book and see what I can learn. Continue reading
