To restore a painting takes the combined skills of a surgeon, a detective and an inventor

In a self-portrait from 1907, the German artist Paula Modersohn-Becker painted herself with a hand over her stomach, suggesting pregnancy, shortly before dying of complications from childbirth. In this short video from the Museum of Modern Art in New York, the art conservator Diana Hartman guides viewers through the delicate process of repairing tears at the edge of the precious painting. Hartman’s surgeon-like skills make use of a set of repurposed tools and shared knowledge developed through trial and error within the small community of art restorers. With each project presenting a unique set of challenges, often requiring many months of planning and painstaking work, conservation calls for improvisation, experience and patience in equal measure – not to mention a switch to decaf coffee to avoid dangerous jitters.

Against ‘beauty’ in science – how striving for elegance stifles progress

That there is an inherent ‘beauty’ and ‘elegance’ to the laws of nature is a view that permeates the field of physics. But, according to the German theoretical physicist Sabine Hossenfelder, the notion that the further you peer into reality, the easier the equation gets, has no basis in reality. Indeed, since the mid-20th-century, the maths of physics has become increasingly knotty, even as many physicists have continued to search for a path back to simplicity. In this interview with Robert Lawrence Kuhn for the PBS series Closer to Truth, Hossenfelder makes the case that this fixation on beauty isn’t just misguided – it’s stifling scientific progress.

Sitting by the fire with a nomadic tribe, a physicist ponders the many shapes of wisdom

The Italian theoretical physicist Carlo Rovelli is a pioneer in the field of quantum gravity, and often thought of as one of the world’s foremost scientific thinkers. In this brief animation by James Siewert, which features narration from the Swazi-English actor Richard E Grant, Rovelli recalls communing with members of the Hadza tribe of northern Tanzania – one of the last hunter-gatherer societies on Earth. Sitting by the fire, thoughts of the peculiar trajectory of Homo sapiens and the many shapes of human wisdom flicker in his head, as he ponders the gaps, large and small, between his world and theirs.

Grieving Kobe Bryant, Conor wonders: why do untimely celebrity deaths hit so hard?

‘It’s weird, like – I’m tearing up for someone I didn’t even know…’

Kobe Bryant’s death on 26 January 2020 in a helicopter crash, alongside his 13-year-old daughter Gianna and seven others, was met with public displays of mourning in the hours, weeks and months that followed. One of the most beloved basketball stars from a league with a global fanbase, the tragedy prompted innumerable tributes to the NBA legend, scrawled everywhere from the sidewalks of Los Angeles to the Chinese social media platform Weibo – alongside plenty of discussions and think-pieces about his complicated legacy, on and off the court.

This short documentary from the US filmmaker Derek Knowles is constructed from phone conversations between Knowles, his brother Conor and the siblings’ parents in the wake of Bryant’s death. Conor, the family’s biggest Bryant fan, meets the news with a distinct combination of shock, sadness and confusion over how the death of someone he never truly knew could affect him so powerfully. The result is a poignant and intricate reflection on celebrity, mourning and death, crafted from just a few intimate words between family members.

Tech companies shroud their algorithms in secrecy. It’s time to pry open the black box

The so-called father of capitalism, Adam Smith, would frown upon the ‘free markets’ of the 21st century, argues the US economics writer Rana Foroohar. For Smith, a functioning market required transparency, a mutual understanding of exchanges and a shared moral framework. And, as Foroohar puts it in this brief animation for the Royal Society of Arts, Manufactures and Commerce (RSA), surveillance capitalism – pioneered by Google, and now, to varying degrees, ubiquitous worldwide – comes up short on all three fronts. Featuring excerpts from a presentation given by Foroohar at the RSA House in London in 2019, this brief animation lays out the many ways in which surveillance capitalism continues to encroach unchecked, and one potential plan for course correction.
