Why Newton’s ‘law of universal gravitation’ is not so universal after all

Isaac Newton’s law of universal gravitation is many things – revolutionary, elegant, mysterious – but, as it turns out, one thing we know for sure is that it’s not, well, universal. On the scale of our solar system, Newton’s observation – that objects attract one another with a force proportional to their mass and inversely proportional to the square of the distance between them – holds up. But, as with so many mathematical laws, when it comes to black holes, things break down. The law also doesn’t work for the kinds of objects we interact with in our daily life, such as people, pencils and peanuts. This scale has proven extremely tricky to measure, and it gets even more imprecise at the scale of particles. This short animated explainer from MinutePhysics dissects the many things we know about gravitational force, and the many things we still have left to learn.

What a ‘good death’ can look like, in the quiet company of a compassionate stranger

‘When I can’t do things for someone else, I simply become unhappy,’ says Loes Prakke, waiting outside the front door of a small house late one evening. She rings, enters and introduces herself to Joop, an elderly man who is sitting up in bed and clearly sick. She tells him she’ll be staying through the night, so that Joop’s loved one, Ria, can get some rest. After acknowledging his hardship, she offers to spend some time chatting so they might get to know one another a bit.

The third volunteer to watch over Joop in his illness, Loes’s warm presence is a simple yet deeply meaningful gift to the couple – a reassurance that Joop will be cared for and comfortable during this final phase of his life. In her short documentary The Final Nights, the Dutch director Reneé van der Ven matches the gentle presence of her subject with her filmmaking, capturing Loes’s extraordinary gift for compassion with a respectful observational style. In chronicling Loes and Joop’s nights together, the film quietly reflects on the meaning of a ‘good death’, as well as the power of human connection in its many distinct forms.

Why a Jackson Pollock masterpiece became an Australian tabloid sensation

The American abstract expressionist Jackson Pollock (1912-56) is a rare artist whose name, style and influence has grown to reach far beyond the art world. But when the National Gallery of Australia in 1973 bought one of Pollock’s most celebrated works, Blue Poles (1952), for a record-breaking sum of US$2 million, it set off a national controversy over the merits of abstract art, as well as about the painting’s place in Australia’s national collection. This short documentary from the New York City-based filmmaker Alison Chernick recalls the unlikely story of how the Australian government’s landmark purchase divided the nation as well as the art world, became an unlikely tabloid sensation, and ultimately found its place in Australian culture.

Parents have long suspected Pokémon rewires kids’ brains. Now there’s evidence

Since 1996, the wildly popular Pokémon media franchise has encouraged kids to geek out over its cast of now more than 800 fictional species. For Jesse Gomez, a neuroscientist at Princeton University, the impact of Pokémon video games presents a unique research opportunity. Inspired by his own childhood love of the original Pokémon Red and Pokémon Blue, which reward the Game Boy player for registering small differences between eight-bit renderings of the characters, Gomez developed an experiment to interrogate how the brain processes visual information.

While pursuing a PhD at Stanford University, Gomez presented images of Pokémon to a group of adults who had played the games as kids and another group that hadn’t, and captured fMRI brain images of the results. Ultimately, Gomez found that, when processed by childhood Pokémon players, the images lit up a small groove in the temporal lobe that remained mostly inactive in the brains of Pokémon newbies. This short documentary from NPR’s show Science Friday tracks how Gomez’s work could potentially lead to a better understanding of learning disorders such as dyslexia and, more broadly, how clever psychological experiments can be sparked by personal experience.

A project to compose music from everyday life is a joyful jolt of pure creativity

The Serbian multimedia artist Miloš Tomić began his Musical Diaries project by seeking out music in everyday life as a form of ‘therapy’ a few years ago. In doing so, he found small sonic surprises everywhere he travelled – objects transformed into improvised instruments and passersby became part of a grand orchestra. Eventually, the idea snowballed into a series of musical video collages – filmed by Tomić and pieced together with the help of some musician friends – that craft audiovisual compositions from his improvisations and discoveries. One such collage, Annual Music Report, mines melodies from sounds found in and around his Belgrade home. The resulting montage, featuring notable contributions from a singer on the Danube river and Tomić’s son Dren, is a singular jolt of joyful creativity, certain to inspire a toe tap and a smile.
