The issue is that Newton’s laws work about twice as well as we might expect them to. They describe the world we move through every day – the world of people, the hands that move around a clock and even the apocryphal fall of certain apples – but they also account perfectly well for a world in which people walk backwards, clocks tick back afternoon to morning, and fruit soars up from the ground to its tree-branch.
“The interesting feature of Newton’s laws, which wasn’t appreciated till much later, is that they don’t distinguish between the past and the future,” says the theoretical physicist and philosopher Sean Carroll, who discusses the nature of time in his latest book The Biggest Ideas in the Universe. “But the directionality to time is its most obvious feature, right? I have photographs of the past, I don’t have any photographs of the future.”
The problem is not confined to the centuries-old theories of Newton. Virtually all of the cornerstone theories of physics since then have worked just as well going forward in time as they do backwards, says physicist Carlo Rovelli of the Centre for Theoretical Physics in Marseille, France, and the author of books including The Order of Time.

Spring came early this year in the high mountains of Gilgit-Baltistan, a remote border region of Pakistan. Record temperatures in March and April hastened melting of the Shisper Glacier, creating a lake that swelled and, on May 7, burst through an ice dam. A torrent of water and debris flooded the valley below, damaging fields and houses, wrecking two power plants, and washing away parts of the main highway and a
One of the most enduring ideas in economics is that free markets bring peace between countries. It comes from the notion that commerce drives humans to follow their mutual material interests rather than make destructive war due to passions.
The French thinker Bruno Latour, known for his influential research on the philosophy of science has died aged 75.
HAVE YOU NOTICED lately that everything is shit? Things were very shitty the year before last, they became even shittier last year, and now everything is just indescribably shit. As a species, we’ve been stuck with this aspect of the human condition for around 300,000 years. But the question of how to respond to it intellectually and emotionally arises with fresh urgency in each new generation. And in the face of each fresh piece of shit. Traditionally, one role of philosophy has been to aid us in this task. Friar Lawrence advises Romeo, banished from his city and the arms of his girl, to sip “Adversity’s sweet milke, Philosophie.” However, over the past couple of centuries, with the transformation of philosophy into an academic discipline, its connection with self-help has largely been severed. The aim of Kieran Setiya’s new book Life Is Hard is to recapture philosophy’s ancient mission of “helping us find our way” in the face of life’s afflictions.
The girls and women of Iran are just bitchin’ brave, flipping the bird at its Supreme Leader in a challenge to one of the most significant revolutions in modern history. Day after dangerous day, on open streets and in gated schools, in a flood of tweets and brazen videos, they have ridiculed a theocracy that deems itself the government of God. The average age of the protesters who have been arrested is just fifteen, the Revolutionary Guard’s deputy commander

One of the funny things about adolescence is that the world can seem enormous, brimming with possibility, while at the same time the urgency to define oneself — fastidiously curating likes and dislikes, ruthlessly sorting people according to their musical tastes — can make the world feel extremely small.
