Splitting the truth: the philosopher that physics forgot

In the early 20th century, Newtonian physics was upended by experiments that revealed a bizarre subatomic universe riddled with peculiarities and inconsistencies. Why do photons and electrons behave as both particles and waves? Why should the act of observation affect the behaviour of physical systems? More than just a puzzle for scientists to sort out, this quantum strangeness had unsettling implications for our understanding of reality, including the very concept of truth.

The German mathematician and philosopher Grete Hermann offered some intriguing and original answers to these puzzles. In a quantum universe, she argued, the notion of absolute truth must be abandoned in favour of a fragmented view – one in which the way we measure the world affects the slice of it that we can see. She referred to this idea as the ‘splitting of truth’, and believed it extended far beyond the laboratory walls and into everyday life. With a striking visual style inspired by the modern art of Hermann’s era, this Aeon Original video explores one of Hermann’s profound but undervalued contributions to quantum theory – as well as her own split life as an anti-Nazi activist, social justice reformer and educator.

Come ice-fishing in the deep Canadian winter with an all-Indigenous, all-female crew

‘Indigenous labour is never just work. It’s cultural practice, our Indigenous knowledge. It’s how we are in the world,’ says the Cree filmmaker Alexandra Lazarowich, discussing her inspiration for her latest short documentary, Lake. Produced as part of the Five Feminist Minutes initiative of the National Film Board of Canada (NFB), this observational short by an all-female, all-Indigenous crew follows Métis women on an ice-fishing outing at Lesser Slave Lake in central Alberta. The sweep of the landscape, the crunch of ice and snow, and the whipping wind evoke the sublime vastness and frigid temperatures of the deep Canadian winter. Within this frozen world, the women are masters of their craft, punching a hole in the ice, dropping their nets through, and eventually pulling their catch to the surface. A richly crafted testament to Indigenous expertise drawing on the style of verité documentaries of the 1960s and ’70s, the film is also an understated acknowledgement of the challenges that Canada’s Aboriginal peoples face in accessing fishing rights – rights that have long been subject to government encroachment.

Your body is scanned, destroyed, then reproduced. Do ‘you’ live on the copy?

For centuries, philosophers – and more recently, science-fiction writers – have been concocting riffs and variations on a particular thought experiment: if every bit of your body could be perfectly scanned and replicated, in what ways would the replica still be ‘you’? In this interview from the PBS series Closer to Truth, Andy Clark, a professor of philosophy at the University of Edinburgh, dissects a version of this experiment posed by the US philosopher Daniel Dennett, in which a body is scanned, destroyed, and replicated in a distant place. While science hasn’t yet brought us close to putting Dennett’s conundrum to the test, we can still grapple with the intriguing and perhaps troubling metaphysical questions it raises, questions that might become even more material as we careen further into the information age, including: would ‘you’ be dead, or would your sense of self perpetuate in the copy? And, if you were recreated several times, where exactly might you expect to find your embodied sense of self?

This bird-of-paradise in New Guinea sounds like something from another planet

Endemic to the mountain forests of New Guinea, the King of Saxony bird-of-paradise (Pteridophora alberti) is best-known for the flamboyant, mate-attracting efforts of its males. The bird’s courtship displays – which often double as a means of keeping competitors at a comfortable distance – make use of bright yellow breast feathers, wildly waving head plumes and peppy dance manoeuvres capped off with an exceptionally outsized, almost otherworldly bit of squawking. This video from the Cornell Lab of Ornithology provides a rare glimpse into the world of this idiosyncratic little bird, which has proven notoriously difficult to photograph in its rugged natural habitat.

‘I live with a girl papa!’ Two years in the life of Alaizah and her trans mother Jade

How to Make a Rainbow is a glimpse into the life of a young girl, Alaizah, and her single mother, Jade, during two especially challenging years. Together, they face the challenges of Jade’s transition from male to female – including new pronouns, unsympathetic family members, stretches of homelessness and top surgery – with high spirits, love and honesty. Ryan Maxey, a Los Angeles-based filmmaker and Jade’s longtime friend, traces the nuances and contours of the duo’s relationship with skill and affection, offering a gentle and intimate rendering of family, and a tribute to the openheartedness of children.
