It’s funny how things change. These days allergies are well understood as a genuine medical matter, they can affect anybody, and they can also be fatal if we’re not vigilant. What’s more, allergies seem to be getting more prevalent in western society. That’s totally turned around from when I was a kid. Back then, allergies … More Why are allergies becoming an epidemic?
One of the reasons I got interested in physics as a kid – and still am today – is because of the way sound works. In physics terms, sound is simply a succession of alternate compressions and rarefications of the air, carrying energy which moves our eardrums. What does that mean? The first point is … More Making waves – the physics of sound
It started raining so hard the other week that animals began lining up two-by-two to board a boat owned by my neighbours. I am only being slightly hyperbolic with that statement. Topsy-turvy weather seems to be the name of the game at the moment, not just in my neighbourhood but right around the world as … More Climate change is humanity’s biggest own goal ever
Have you ever noticed how, more often than not, pictures of ‘early humans’ in action often show them walking somewhere. And the pop-image of our evolution, unscientific though it actually is, has much the same imagery. Part of that is because there’s empirical evidence that ancestral humans did walk a lot, and various tracks have … More The endless human journey…
The passing of Stephen Hawking marks the end of an era. He was an extraordinary man and an exceptional physicist – one of the greats, standing alongside Einstein, Bohr, Newton, Heisenberg and a small and select handful of others. He was also an exceptional human on many levels, offering wisdom and insight into much about … More The legacy of Stephen Hawking
We’re in the middle of yet another revival of 3d movies at the moment – and I can’t help thinking they look a bit rubbish as 3d. Just like they did the first time round, over 60 years ago. Back in the 1950s, TV was going to kill the movies stone dead. Yup, movies were … More So this is why 3D movies never take off
Lately space science has made a slightly disturbing discovery. Space travel makes you go blind. Really. It’s a bit of a surprise, given that in other ways science has found solutions for most of the biomedical problems of free fall and, along the way, learned an awful lot about osteoporosis, which is a spinoff of … More Don’t space travel. You’ll go blind.
