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.

‘Then – fit our Vision to the Dark’: exploring sight with Emily Dickinson

Written by Emily Dickinson during the depths of the US Civil War, the untitled poem known as ‘We Grow Accustomed to the Dark’ conjures hope and perseverance amid waves of chaos and uncertainty. In this animation, the UK filmmaker and illustrator Hannah Jacobs visualises the poem in fleeting scenes that oscillate between vibrant colour and darkness, through which human figures careen. Beginning with an epigraph drawing a parallel between artistic and scientific discovery, the video was created for an online neuroscience course at Harvard University as part of a series that explores the human sensory experience through poetry and animation.

Life emerges, evolves and fights for supremacy in this 1929 avant-garde classic

The New Zealand-born artist Leonard Charles Huia Lye (1901-80), better known as Len Lye, is renowned for his work in kinetic sculpture and experimental film, and is widely considered one of the most innovative modernists of the 20th century. Lye’s first film, Tusalava (1929), produced over two years following a move to London, was born of the city’s emerging experimental film scene and Lye’s abiding interest in Maori, Aboriginal and Samoan art. Composed of some 7,000 hand-drawn images, the abstract animation synthesises modern and ancient art as it depicts simple life forms emerging, evolving and coming into conflict. As with the influence of African art on Pablo Picasso, Lye’s use of so-called ‘primitivism’ has been both praised for introducing non-Western perspectives to Western art, and criticised for cultural appropriation. The film was originally paired with a now-lost piano score from the UK-born composer Jack Ellitt. This version features the UK composer Eugene Goossens’s composition Rhythmic Dance (1928), which Lye later suggested as an alternative accompaniment.

If simple logic isn’t working with your internet company, try Zermelo-Fraenkel set theory

This tongue-in-cheek animation from the US YouTuber Henry Reich – the mind behind MinutePhysics – is a creative exercise in how not to lose your cool when faced with the abyss of illogic. Recalling the mundane, mindnumbing tribulations of trying to get a straight answer on billing from his internet service provider (ISP), Reich concludes that the company isn’t just guilty of subpar customer service – their policies also break nearly every fundamental law of modern mathematics. Reich’s clever excoriation of telecommunication companies was created for The Festival of Bad Ad Hoc Hypotheses (BAHFest), an annual ‘celebration of well-argued and thoroughly researched but completely incorrect scientific theories’.

Mind control and zombification do exist. Just look at these crickets

Warning: this video is not for the squeamish.

Mayflies make a quick and nutritious snack for crickets. But, rather unfortunately for the cricket population of California, some mayflies are home to hairworms (nematomorphs) – parasitic creatures that will stop at nothing to make their way back to water. Once consumed, hairworms feed off crickets from the inside, absorbing all of their lipids, and eventually putting the cricket in a state of developmental and reproductive limbo. Worse still, once these fast-growing parasites reach their adult length of one to two feet, they zombify their hosts, unleashing brain chemicals that make the infected crickets wander aimlessly until they hit water, where the worms make their final escape and start the whole cycle anew. By studying this process, scientists hope to learn more about how brain parasites might affect human behaviour. The ordeal is captured in microscopic detail in this episode of the often creepy, always fascinating science documentary series Deep Look. Read more about the video at KQED Science.
