Theorectical Physics: The ‘Constructor Theory’ Of Oxford’s Chiara Marletto

“Declaring something impossible leads to more things being possible,” writes the physicist Chiara Marletto. “Bizarre as it may seem, it is commonplace in quantum physics.”

Chiara Marletto is trying to build a master theory — a set of ideas so fundamental that all other theories would spring from it. Her first step: Invoke the impossible.

Constructor Theory is a new approach to formulating fundamental laws in physics. Instead of describing the world in terms of trajectories, initial conditions and dynamical laws, in constructor theory laws are about which physical transformations are possible and which are impossible, and why. This powerful switch has the potential to bring all sorts of interesting fields, currently regarded as inherently approximative, into fundamental physics. These include the theories of information, knowledge, thermodynamics, and life.

Islands: The Unknown Rural Side Of Santorini

Santorini is one of the Cyclades islands in the Aegean Sea. It was devastated by a volcanic eruption in the 16th century BC, forever shaping its rugged landscape. The whitewashed, cubiform houses of its 2 principal towns, Fira and Oia, cling to cliffs above an underwater caldera (crater). They overlook the sea, small islands to the west and beaches made up of black, red and white lava pebble.

Julia’s journey brings her to the glamorous island of Santorini, where she discovers how one of the Aegean’s poorest islands became a playground for the rich and famous.

Political Analysis: Is Taiwan Part Of China?

If countries were people, the relationship between China, America and Taiwan would be a love triangle like no other.

Taiwan is by some reckoning the most dangerous flashpoint between China and America. Though Taiwan is in most respects an independent country, China insists it is part of the People’s Republic and is not ruling out taking the island by force. If that were to happen it could ignite an all-out war between America and China. This film explains how this precarious situation came about and how might it play out.

New Wildlife Books: ‘Last Of Their Kind’ By Joachim Schmeisser (April 2021)

“Some of the largest and most wonderful creatures in Africa have become very dear to me over the years,” Schmeisser writes. His book of portraits carries two messages. “It [is] a homage and warning at the same time—a visual message with the aim of sharpening our clouded view of the one, infinitely complex and vulnerable nature and to recognize which treasures we are about to irretrievably lose,” he writes.

There are exactly two black rhinos left in the world, a subspecies of the white rhino, the very last of their kind. In this deeply poignant tribute, photographer Joachim Schmeisser presents these rhinos as well as other wild animals in the Amboseli National Park in Kenya, where Maasai tribespeople ensure that nobody endangers them. With his breathtaking black-and-white images, Schmeisser brings us up close to these extraordinary and endangered creatures, creating a powerful document of nature’s splendor and fragility.
