El traveling cenital que recorre el columpio, el cine, la iglesia y la escuela en "The Long Day Closes" (1992) de Davies es un encadenado genial que articula una canción con el mismo propósito que sus transiciones: evocar retazos de ese misterio que llamamos tiempo. Una delicia.

The AMOC has reliably transported heat from the equator to the North Atlantic for the past 12,000 years, and sporadically for a lot longer than that. It’s the reason Europe is warmer than its latitude would suggest. Its collapse would be an irreversible ramping up of planetary climate chaos—a paradoxical deep freeze on a warming planet, with New England and especially Europe getting much colder temperatures and higher sea levels (in fact sea levels near me are already elevated from AMOC weakening). Like the date of its collapse, the overall effects are not fully known, but the AMOC has global impacts, regulating weather systems that feed billions. This isn’t just one more thing we’ll have to learn to live with; it would be calamity, a tipping-point-of-no-return that will split human history in two.

Mysterious ‘cold blob’ in the Atlantic suggests the AMOC is weakening

A patch of ocean south-east of Greenland is the only place on Earth that is cooling, and it could be a sign that the warm water “conveyor belt” in the Atlantic is slowing down

At age 25, Kurt Gödel proved there can never be a mathematical “theory of everything.” In this week’s Qualia column, @nattyover asks experts how his ideas changed the course of humanity’s unending search for truth. https://t.co/UVDtVlYJkZ

Columnist Natalie Wolchover spent the early weeks of the pandemic learning how the 25-year-old Austrian logician and mathematician Kurt Gödel established that no formal system of math can ever be complete.

“Oh yeah, that time you almost went crazy?” was how her wife remembered it.

Harvey Friedman — the youngest professor in Stanford's history, founder of reverse mathematics, and the mathematician Kurt Gödel personally chose to sponsor his final paper — has spent 60 years on a single, audacious question: can ordinary, finite math be trusted? His theorems suggest otherwise, showing that even the most concrete and natural mathematical statements — involving nothing more exotic than rational numbers — cannot be proved or refuted within the gold standard of mathematical foundations, ZFC. The foundations of mathematics, Friedman argues, are not settled bedrock but something far more vertiginous: totally up in the air, and made more mysterious, not less, by his own work.

This fake trailer for The Shining practically launched the early YouTube trend of creating wildly misleading trailers for well-known films—and in my opinion, none of the imitators ever quite matched it.

If reality's fundamental building blocks are conscious, how do they combine to produce a complex mind?

This question haunts panpsychism, and thinkers from William James to David Chalmers have struggled to answer it.

Philosopher S. Siddharth argues the solution lies within the strange metaphysics of Gottfried Leibniz.

Reviving Leibniz’s “monads,” Siddharth envisages a reality composed of indivisible centers of experience, which neither fuse nor split, but are rigorously singular, sidestepping the question that plagues popular versions of panpsychism.

Sir Roger Penrose just delivered a masterclass in physical skepticism.

In this sharp exchange with Brian Cox, he dismantles the dangerous allure of mathematical aestheticism. We often fall into the trap of assuming that if an equation is beautiful, it must be true.

But Sir Roger warns that "beauty is a misleading guide." String Theory, for all its intricate Calabi-Yau manifolds and vibrant 11-dimensional symmetries, remains an elegant mathematical construct yet to be anchored by empirical data.

It’s a sobering reminder: the universe is under no obligation to conform to our human standards of "pretty" math. Reality is gritty, and sometimes the truth lies in the most "unattractive" corners of entropy.

[Give A Shit About Nature @giveashitnature]

Migrating fish in Utrecht were getting stuck at a canal lock. Two ecologists fixed the problem with a doorbell.

It's called the Visdeurbe, or the "fish doorbell."

Every spring, fish migrate through the city's canals to spawn in shallow upstream waters. But the old Weerdsluis lock, built in the 1600s, stays mostly closed in early spring because boat traffic is low.

Fish pile up against the gate with nowhere to go. Predators find them, and many don't make it.

Two ecologists in Utrecht had an idea. Put an underwater camera on the lock, livestream it, and let anyone on Earth press a digital doorbell when they see fish waiting.

The lock keeper opens the gate when enough people have rung in.

In 2024, the doorbell was pressed 150,000 times by viewers from Germany, the US, the Netherlands, the UK, and dozens of other countries.

Over 20 million people tuned in to watch. Thousands of fish got through: perch, bream, pike, rudd, catfish, even eels.

You don't have to live in Utrecht to help. You can open your laptop right now and help a fish in the Netherlands get to where it's going.

This should be a bigger story. 

Scientists are more concerned than ever that a critical Atlantic current will collapse soon and wreak havoc on North America and Europe. The Atlantic Meridional Overturning Circulation, or AMOC, is a massive conveyor belt of ocean currents that transports water from the tropics to the Atlantic. 

Without it, severe weather would impact both regions at potentially devastating rates.

These scientists aren't just warning us about an environmental issue—they're sounding the alarm about a climate threat that could fundamentally rewrite how future generations survive on our planet.

"Touch" is one of the universe's greatest illusions.

When you hold someone’s hand, your atoms aren’t actually meeting; they are resisting each other through electromagnetic forces. We are literally floating on a sea of quantum resistance every single day.
