Time’s Arrow Traced to Quantum Source

Coffee cools, buildings crumble, eggs break and stars fizzle out in a universe that seems destined to degrade into a state of uniform drabness known as thermal equilibrium. The astronomerphilosopher Sir Arthur Eddington in 1927 cited the gradual dispersal of energy as evidence of an irreversible “arrow of time.” But to the bafflement of generations of physicists, the arrow of time does not seem to follow from the underlying laws of physics, which work the same going forward in time as in reverse. By those laws, it seemed that if someone knew the paths of all the particles in the universe and flipped them around, energy would accumulate rather than disperse: Tepid coffee would spontaneously heat up, buildings would rise from their rubble and sunlight would slink back into the sun. “In classical physics, we were struggling,” said Sandu Popescu, a professor of physics at the University of Bristol in the United Kingdom. “If I knew more, could I reverse the event, put together all the molecules of the egg that broke? Why am I relevant?” Surely, he said, time’s arrow is not steered by human ignorance. And yet, since the birth of thermodynamics in the 1850s, the only known approach for calculating the spread of energy was to formulate statistical distributions of the unknown trajectories of particles, and show that, over time, the ignorance smeared things out. Now, physicists are unmasking a more fundamental source for the arrow of time: Energy disperses and objects equilibrate, they say, because of the way elementary particles become intertwined when they interact — a strange effect called “quantum entanglement.” “Finally, we can understand why a cup of coffee equilibrates in a room,” said Tony Short, a quantum physicist at Bristol. “Entanglement builds up between the state of the coffee cup and the state of the room.” (via Quantum Entanglement Drives the Arrow of Time, Scientists Say  Simons Foundation)

Just press play and listen
god damn it it works.
it works, and that’s the greatest crime of all.who made this, arrest them.
are you effing serious
mother. fucker.
Welp I know what’s gonna be the last track on the next gift cd I make.

The Mathematical Formula for Beauty, Explained in Clever Pictures

Mathematical concepts can be difficult to grasp, but given the right context they can help explain some of the world’s biggest mysteries. For instance, what is it about a sunflower that makes it so pleasing to look at? Or why do I find the cereal boxshaped United Nations building in New York City to be so captivating? Beauty may very well be subjective, but there’s thought to be mathematical reasoning behind why we’re attracted to certain shapes and objects. Called the golden ratio, this theory states there’s a recurring proportion of arrangement that lends certain things their beauty. Represented as an equation: a/b = (a b)/a, the golden ratio is all around us—conical sea shells, human faces, flower petals, buildings—we just don’t always know we’re looking at it. In Golden Meaning, a new book from London publisher GraphicDesign&, 55 designers aim to demystify the golden ratio using clever illustrations and smart graphic design.
