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.

A waltz with a year’s worth of weather radar is both predictable and mysterious

From the tornadoes of the Great Plains to the hurricanes of the Gulf Coast, the United States has some of the world’s most notoriously destructive and volatile weather. But while somewhat hard to grasp on local, week-to-week scales, the nation’s weather is characterised by noticeable and much more predictable patterns when viewed at a macro level. This engrossing timelapse from the YouTube channel Weather Decoded uses radar to follow the meteorology of the entire continental US for all of 2018. As the video unfolds, perennial patterns, such as clouds losing steam when pushing up against the Sierra Nevada mountain range, and seasonal trends, including a stormy June for Nebraska and Kansas, reveal themselves. While US-centric, the video offers an insightful glimpse into the ways in which weather is both predictable and mysterious.

In Silicon Valley’s shadow, a boy bids farewell to the trailer community that’s been home

In the wake of the Silicon Valley tech boom, a massive housing affordability crisis has left thousands of lower-income residents unable to pay skyrocketing rents. These conditions have led to a steep rise in homelessness and the emergence of makeshift housing in the shadows of some of the wealthiest neighbourhoods in the world. In her deftly crafted short documentary Crisanto Street, the US filmmaker Paloma Martinez explores one such streetside mobile-home community through the eyes of Geovany Cesario, a cheerful eight-year-old whom she casts as guide, interviewer, narrator and occasionally camera operator. On the eve of his family’s move from their trailer to a low-income apartment complex, Geovany takes us on a touching and bittersweet farewell tour of his world until now.

How an unplanned picture from Apollo 8 altered humanity’s perspective of Earth

‘What they should have sent was poets…’

Launched in December 1968, Apollo 8 was the first manned flight to reach the Moon, orbit it and return to Earth. The primary goal of the mission was to prepare for an eventual lunar landing, however, the flight is now best remembered for the unparalleled glimpses of Earth it provided and, in particular, the iconic photograph taken from lunar orbit that became known as ‘Earthrise’. Coinciding with the 50th anniversary of Apollo 8, this documentary from the US director Emmanuel Vaughan-Lee features interviews with the crew members Frank Borman, James Lovell, and William Anders, who took the famed picture. While reflecting on the life-changing experience of being the first people to view the Earth from outside of its orbit in the ‘inky black void’ of space, they detail how the unplanned photograph became their mission’s most lasting legacy, and gave them a newfound appreciation of their home planet.

Want to make a lab rat smarter? Treat it like a smarter lab rat

It’s perhaps not startling to learn that the expectations of others have a significant impact on us. Over the past century, however, scientists have been surprised to observe just how forcefully expectations can nudge the abilities of people – and rats – in one direction or another. Featuring audio excerpts from NPR’s Invisibilia podcast, this animation draws on the work of the US psychologists Robert Rosenthal and Carol Dweck to briefly delve into how expectations can raise or lower student performance, speed up or slow down soldiers, and make maze-solving lab rats smarter or dumber.
