“Our trained mediums are standing by”

Watching Mali Elfman’s Next Exit for New Scientist, 22 February 2023

From out of nowhere, a chink of light appears. With painful slowness, the light grows stronger: we are inching towards a half-open door. Beyond the door, everything seems normal. A little boy is playing a game of pretend. At least, that’s what we think. Soon enough, we learn what’s really going on: the boy is playing cards with his dead father.

Nothing else in Mali Elfman’s debut feature lives up to this unsettling opening sequence (though there’s a sight gag — two would-be suicides renting a car from Charon Vehicle Rental — that comes close).

Rahul Kohli and Katie Parker — actors who turn up regularly in work by horror director Mike Flanagan — play Teddy and Rose, driving across the US to an appointment with Dr Stevensen (Karen Gillan) who has promised them a clinically managed euthanasia. Teddy, a Londoner, has spent ten years trying and failing to make it in the United States, and figures that being turned into a pioneer ghost (his transition from life to death monitored with all the latest gear) will at least give his life some meaning. Rose is weighed down with guilty secrets, and just wants to be done with it all.

Mind you, even Rose is not as nihilistic as the man who, early on in the film, wonders in front of their hire car, and under their wheels, with a note pinned to his chest: “Thanks for the help”.

Suicides and homicides are common now, as Heaven beckons (or whatever passes as Heaven), and our hardscrabble lives on this ordinary Earth lose their preciousness and meaning. “Our trained mediums are standing by,” a radio advert announces, offering contact with the newly visible dead. This is a world lost to itself, snared by fantasies of the hereafter.

But what do these newly discovered ghosts really want, as they stream into our world through every available screen? Not every haunting is as touching as that of the boy and his dead parent. Rose guzzles bourbon by the bottle so as not to see her mother watching her from inside the motel pay-per-view. A friendly cop, caught up in a drinking game, confesses to a thoughtless on-duty prank that killed a family of five; not surprising then, that he thinks “they’re here to hurt us.” Karma, a hitchhiker Teddy and Rose pick up out in the desert, has her own doubts: ”Just because we can see them,” she points out, “doesn’t mean we understand them”.

It’s at this point, about half way into the movie, that the viewer’s heart, if it does not immediately sink, certainly begins to tip: surely this film has bitten off way more than it can possibly chew?

Teddy admits that what he really wants out of his own managed death is for the news to get back to his absentee father: “I’d rather kill myself than live the life you gave me.” This is not a bad line, but what follows is horrific, and not in any intended way: a stage-managed confrontation with Teddy’s dad; an impromptu psychodynamic therapy session in a filling station car lot. The script rights itself, but having lost all confidence after this compound pratfall, it delivers, in the end, only a low-key retread of Joel Schumacher’s 1990 flick Flatliners. (Judgement waits for us all; struggle gives life its meaning; you know the rest.)

Next Exit is a promising film, but not a good film. It warps the world into a very strange shape, to ask some valid — indeed, pressing — questions about where the value of life resides. But it loses its way. If the writing had exhibited half as much commitment as the acting, we might have had a hit on our hands.

A surprisingly narrow piano

Reading Richard Mainwaring’s Everybody Hertz for the Spectator, 30 April 2022.

Imagine that all the frequencies nature affords were laid out on an extended piano keyboard. Never mind that some waves are mechanical, propagated through air or some other fluid, and other waves are electromagnetic, and can pass through a vacuum. Lay them down all together, and what do you get?

The startling answer is: a surprisingly narrow piano. To play X-rays (whose waves cycle up to 30,000,000,000,000,000,000 times per second), our pianist would have to travel a mere nine metres to the right of middle C. Wandering nine and a half metres in the other direction, our pianist would then be able to sound the super-bass note generated by shockwaves rippling through the hot gas around a supermassive black hole in the Perseus cluster — a wave that cycles just once every 18.5 million years.

Closer to home, how big do you think that piano would have to be for it to play every note distinguishable by the human ear? You’d have to add barely a single octave to either side of a regular concert grand.

Readers of Richard Mainwaring’s wonderfully titled book will fall into two camps. Some will want to hear what this “infinite piano” conceit reveals about the natural world; about the (considerable) auditory abilities of spiders, say, or how 23 high-stepping fitness junkies caused a tremor that evacuated the the 39-storey Techno Mart building in Seoul, South Korea.

Other readers, though entertained well enough by Mainwaring’s extraordinary clear and concise science writing, won’t be able to get that infinite piano out of their heads. It’s a metaphor so engaging, so intuitive, it’s quite as exciting as anything else in the book (for all that the book features ghosts, whales, Neolithic chambered cairns and Nikolai Tesla).

Mainwaring is a musician and a composer, and the business of music runs under even his most abstruse intellectual excursions. A Marsquake recorded on On 6 April 2019, sped up by a factor of 60, sounds, he tells us, “not unlike someone blowing over the top of a half-full wine bottle in Westminster Abbey”. Fully concentrating on a task generates brainwaves of around 40 Hz or more: ”it’s a wonder we can’t hear them humming, as they are at the same frequency as the opening bass note of Cypress Hill’s ‘Insane in the Brain’.”

This is infotainment at its most charming and lightweight; tonally, it’s of a piece with the musical stunts (for example, arranging a performance by massed tuning-forks) that Mainwaring has regularly staged for BBC1’s pre-watershed magazine programme The ONE Show. The glimpses Mainwaring gives us into the peculiar, fractured, distraction-filled business of modern music making are quite as fascinating as his tales of planetary resonance and the latest thinking about olfaction. He can also be tremendously catty, as when he pricks the vaingloriousness of virtuoso bass players (“Know your role, bassists – stay out of the way.”)

Like any ebullient teacher, he won’t be everybody’s cup of tea. There’s always one misery-guts at the back of the class whose teeth will be set on edge, and now and again Mainwaring’s humour is a little forced. This is usually because he’s hit on some neat metaphor and doesn’t know when to stop beating on it. We should set against this, though, his willingness to dive (and deeply, too) into any number of abstruse subjects, from religious experiences to Edwardian vibrators.

Throughout, Mainwaring keeps a sharp eye out for specious claims and pretensions. There is, he says, nothing magical about “the God-given, superhero ability of perfect pitch” — the ability to identify a note from its frequency. Indeed, before 1955, the year the ISO standardised “A” at 440 Hz, there was no such thing as perfect pitch. (Interestingly, though, speakers of Mandarin, a language dependent on tonal inflexion, are rather better at guessing notes than the rest of us.)

On the other hand there is, as Mainwaring ably demonstrates, an extraordinary spiritual power to music, particularly around the note A forty-seven white keys to the left of middle C. (That’s 19 cycles per second, or 19 Hertz, we say now, in honour of Heinrich Rudolf Hertz, who proved the existence of electromagnetic waves). This “A” can trigger cold sweats, fits of severe depression, and even sightings of dead people. Mainwaring traces the use of low notes and infrasound from the more inaccessible tunnels of French caves (where little ochre dots marked where prehistoric singers should stand to sound especially resonant and amplified) to Bach’s Toccata and Fugue in D Minor which, on any decent organ, generates infrasonic byproducts by means of two chords and a low pedal D.

Though horribly abused and exploited by various new Age fads over the years, the old intuition still holds: vibrations reveal much about life, consciousness and the integrity of matter. Mainwaring’s clear-eyed forays into medicine, psychology and spirituality reflect as much.

It’s a commonplace of popular science that the world is looked at best through this or that funny-shaped window of the author’s choosing. But Mainwaring’s garrulous offering is the real deal.
