Let’s face it, quantum mechanics mystifies most of us. But as Quantum Drama shows, it baffled its creators, too – so much so that some of them turned to suicide, drink, or psychiatry (Carl Jung was a favourite). Who wouldn’t go crazy, trying to get their head around such bizarre happenings as subatomic particles sometimes being wave-like, and a theory that cannot tell you the particle’s definite state – its position and velocity, say – before you measure it? In ordinary ‘classical’ physics, by contrast, you can predict in advance every point on the trajectory of an ordinary object, such as a ball or a spacecraft, launched from any given place with any particular velocity. But quantum theory does not play by these long-established rules: until you observe the particle, all the theory can tell you are the chances it will show up at various places. As Einstein asked, ‘Do you really believe the Moon is only there when you look at it?’

An anthology dedicated to the transnational history of psychedelic drugs and culture seems a timely enterprise. We are twenty or so years into what has become known as the ‘psychedelic renaissance’, the global revival of interest in compounds such as LSD, mescaline, and psilocybin centring on their use alongside psychotherapy as treatments for a growing number of mental health disorders.

During a recent lunar eclipse, I marvelled as Earth’s shadow nibbled away the Moon’s light. This creeping shadow testified to the awesome movement of the celestial spheres, Earth inching along its trajectory around the Sun while the Moon fell around Earth until, on this special night, all three bodies were closely aligned in the same plane: Sun, Earth, Moon. A related alignment occurs each month, when the Sun’s light is reflected from the full, uninterrupted Moon. We can see it because the Moon orbits Earth in a slightly different plane from that of Earth’s motion around the Sun. But on this night, the Moon was passing through a point where these two planes intersected, so that Earth directly blocked the light from Sun to Moon.

The photograph arrives while I am reading Dave Witty’s What the Trees See. A tree’s branch close-up, outer brown-red bark peeled back to smooth and brilliant green. A friend, spotting it on Quandamooka Country in Minjerribah, North Stradbroke Island, has been understandably stopped in her tracks. Framed intimately like this, its shape and textures suggest warm musculature: lean in, you will be held. This beautiful creature.

In 2019, Smithsonian magazine published a profile of an American inventor, entrepreneur, and undersea explorer named Stockton Rush. Rush and his company, OceanGate, had recently celebrated the successful descent of their experimental manned submersible Titan to the extraordinary depth of 4,000 metres. Titan’s design was innovative in two important ways: its body was composed centrally of carbon fibre, which made it light and comparatively inexpensive to operate, and it was a cylinder. A spherical sub might have had ‘the best geometry for pressure’, observed Rush, ‘but not for occupation’ – and this represented an unpalatable check on OceanGate’s plans to deliver groups of high-paying tourists to the wreck of the Titanic. ‘I had come across this business anomaly I couldn’t explain,’ Rush reflected: ‘If three-quarters of the planet is water, how come you can’t access it?’

The Best Australian Science Writing (BASW) anthology is here again, and readers are in for a treat: a wide-ranging selection of easy-to-read articles describing some of the amazing science that is happening right now.

Of course, it is an impossible task, choosing the ‘best’ writing, and in her introduction editor Donna Lu acknowledges her subjectivity. It is the same for a reviewer, and since I don’t have room to name everyone, I won’t single out my own favourites.
