Black Mirror's new season is a mixed bag, ranging from a sublimely plotted romp to one of the worst episodes to date. And it's still playing fast and loose with its sci-fi concepts, finds Bethan Ackerley

Photographer Mitch Epstein's years-long project highlights the majesty and vulnerability of old growth forests across the US

Why is saying no to other people so difficult – even when we really know we should? Sunita Sah's new book Defy has some novel ideas about the interpersonal forces holding us back

General relativity is an astonishingly beautiful theory, and grappling with why it disagrees with quantum mechanics is a joy, says Chanda Prescod-Weinstein

Feedback was pleased to come across journalist Taylor Lorenz's coining of the word "viralflation", as videos with hundreds of millions of hits proliferate across the internet

The idea that the rise of tech means today's young people are less intelligent than previous generations is rife – but wrong, says neuroscientist Dean Burnett

Exposing the origins of the improbable – and at times scary – plans of tech billionaires makes Adam Becker's More Everything Forever a disturbing but important book

Quantum theory started with a bout of hay fever, and went on to transform our view of the universe – but its legacy isn't complete

Quantum effects like superposition and entanglement have long been seen in single particles, but physicists are on a quest to find out just how big an object can be before it loses its quantumness

There were hints that the world may be quantum long before the development of quantum mechanics in 1925 – could we have come up with this revolutionary theory hundreds or even thousands of years earlier?
