Kentanji Brown Jackson is too good for this court. I don’t have a transcript yet but she basically asked: “Didn’t they put birthright citizenship in the constitution in order to avoid this type of debate over who gets to claim a domicile?” And Sauer just stuttered. And then Sonia Sotomayor comes in with the “doesn’t this open the door to the government withdrawing citizenship from people who were born here?” More stuttering.

Over 2,200 years ago, a Greek librarian named Eratosthenes measured the entire planet with a stick and got it right to within 100 miles. He didn’t have satellites or GPS or even a telescope. Just shadows and a guy he hired to walk between two Egyptian cities. His answer was about 25,000 miles around. The real number is roughly 24,900. Less than 1% off. In 240 BC. That photo up there is from the International Space Station, about 250 miles above us. The ISS whips around the planet once every 90 minutes. Sixteen sunrises, sixteen sunsets, every single day. Astronauts have taken over 3.5 million photographs of Earth from up there. Nearly 300 people from 26 countries have floated up and seen the curve with their own eyes. And yet. According to a 2018 YouGov poll of over 8,000 adults, only 84% of Americans firmly said the Earth is round. Among 18 to 24 year olds, that dropped to 66%. A separate 2021 survey put the share who think Earth is flat or aren’t sure at about 1 in 10. In December 2024, a guy from Colorado named Will Duffy spent three years planning and about $35,000 per person to fly some of the biggest flat-earth YouTubers to Antarctica. Near the South Pole during summer, the sun never sets. It stays up for 24 straight hours, circling across the sky, because the Earth is tilted on its axis and the bottom of the planet faces the sun. On a flat earth, that is physically impossible. They live-streamed the whole thing via Starlink. The sun didn’t set. Jeran Campanella, one of the most-watched flat-earth creators on YouTube, went on camera and said he’d been wrong about the 24-hour sun. The rest of the flat-earth community called it a green-screen fabrication. I went pretty deep on this one. What gets me is the timeline. Eratosthenes nailed it with a stick in 240 BC. We’ve got 3.5 million photos from orbit. A group of flat-earthers watched the sun circle Antarctica for three days, and parts of the community still called it staged. The evidence has been stacking up for 23 centuries and the gap between what we can prove and what people will accept keeps widening.

Volodymyr Zelenskyy / Володимир Зеленський
I spoke with His Holiness Pope Leo XIV @Pontifex today. At the very moment of our conversation, the Russians attacked Ukraine yet again – hundreds of “shaheds” and dozens of missiles against our cities and communities. In fact, the attack has been ongoing in waves since last night, and at least five regions have already been targeted. Not a single hour of peace for our people, and this is Russia’s response to our proposal for an Easter ceasefire. Essentially, the Russians have only intensified their strikes, turning what should have been silence in the skies into an Easter escalation. This certainly cannot be ignored, and I am grateful to everyone in the world who does not remain quiet about it. I spoke about the negotiation process and our work with the American team. I also expressed gratitude for the assistance in returning our abducted children and for all the humanitarian aid the Vatican has provided to our people, particularly during this difficult winter. We also discussed the situation in the Middle East and the Gulf region. I wished His Holiness and all those celebrating Easter this Sunday a blessed holiday and peace. Of course, we would be glad to welcome His Holiness to Ukraine on an apostolic visit. And I am especially grateful that the Pope remembers Ukraine, the Ukrainian people, and prays for peace for our nation.

BREAKING🚨: Astronaut Captures Rare Luminous Phenomenon from Earth Orbit. From hundreds of kilometers above Earth, an astronaut has photographed one of the planet’s most elusive atmospheric displays—an ethereal burst of light that flickers above thunderstorms. 😮 These phenomena, known as sprites or blue jets, briefly illuminate the upper reaches of the atmosphere, puzzling scientists and thrilling skywatchers. Recorded in stunning detail from orbit, the image reveals the extraordinary interplay between weather, electricity, and space

🚨 The main reason millions of schoolkids watched the Challenger disaster live is because Christa McAuliffe was the first teacher in space. NASA set up special satellite feeds, schools across the country rolled in TVs It wasn’t “almost no one” it was a huge deal in classrooms

"Encouraged by this blatant corruption, Trump’s most ardent supporters are demanding their own cut. This week, a group of J6 rioters filed a class action demanding recompense. The stage is set for the wholesale looting of the federal coffers by Trump and his MAGA allies." publicnotice.co/p/january-6-se…

A professor of engineering who failed math all through school built one of the most popular online courses in history by figuring out exactly why her brain had been working against her the whole time. Her name is Barbara Oakley, and she did not teach herself how to learn until she was in her mid-twenties, after leaving the military with a head full of Russian and almost no useful science knowledge. What she discovered about her own brain eventually became a Coursera course that over 4 million people have taken, and the core insight she teaches has been sitting in neuroscience research for decades waiting for someone to explain it in plain language. Here is the framework that changed how I think about every hard thing I am trying to learn. Your working memory is an octopus sitting in your prefrontal cortex with exactly four arms. Those four arms reach out and grab pieces of information, hold them in place, and manipulate them while you are actively thinking through a problem. Four is the limit. When you try to hold more than four things in conscious awareness at once, the arms start dropping things and everything becomes a scramble which is exactly what you experience as confusion when learning something genuinely difficult. This is not a flaw. It is a design feature. And the entire game of becoming expert at anything is learning how to game this constraint. The mechanism is something neuroscientists call chunking, and it is the most underexplained concept in all of learning. When you practice something enough times that it becomes automatic a guitar chord, a grammatical structure, a mathematical procedure, a debugging pattern in code your brain compresses it into a single neural package stored in long-term memory. That compressed package now fits in just one of your four working memory slots instead of filling all of them. Which means once you have built enough chunks, your octopus can reach down into long-term memory, pull up an entire complex procedure in a single grab, and still have three arms free to work with new information on top of it. This is what expertise actually is. Not raw intelligence. Not natural talent. A library of compressed patterns that can be retrieved quickly and stacked together to solve problems that would overwhelm a beginner whose working memory is still occupied with fundamentals. The finding that Oakley emphasizes most forcefully is the one that sounds backward until you understand the mechanism. People with smaller working memory capacity those who can only hold two or three items at once rather than four are often forced to develop stronger chunking habits earlier and more aggressively than people with larger working memories, because they have no choice. Their constraint becomes their training. Over time, that aggressive chunking practice can produce more robust expertise than a larger working memory that never had to be disciplined in the same way. The most powerful practical implication is this: when you feel completely overwhelmed trying to learn something, that feeling is almost always your four-slot octopus running out of arms. The solution is not to concentrate harder. The solution is to stop, isolate one small piece of the problem, practice it until it compresses into a single chunk, and only then pick up the next piece. You cannot learn everything at once because your brain was never designed to hold everything at once. It was designed to build libraries of compressed knowledge and retrieve them on demand. Every expert you have ever admired is not smarter than you. They just have a bigger library.

BREAKING🚨: The Artemis II astronauts will go through the most tense moment of the mission on April 6, 2026. This is the highlight of the entire mission. The Orion will pass between 6,400 and 9,600 kilometers above the lunar surface. But there's a detail that makes this moment even more intense: as it passes over the far side of the Moon, the spacecraft will lose communication with Earth for about 30 to 50 minutes, blocked by the Moon itself. "For the 45 minutes when we'll be closest to the lunar surface, we'll also be out of contact," said Victor Glover, the mission's pilot. "I'd love for the whole world to be cheering and praying for us to reestablish the signal." During that time, the astronauts will photograph and observe regions of the Moon's far side that have never been seen by human eyes. The crew will also attempt to capture new images of the so-called Earthrise, the planet emerging over the desolate lunar surface.

In Jan 2025, he said Elon Musk was going the balance the budget with DOGE finding fraud. On 2/2/25 he said tariffs would balance the budget. On 6/2 he said OBBB would balance the budget. On 6/12 he said Trump Cards would balance the budget. Now he says Vance will do it.

St Kitts and Nevis become first Caribbean nation to recognise Rastafari faith in law The Prime Minister further highlighted the importance of respecting Rastafari not only as a religion, but as a way of life that is deeply rooted in the identity of many citizens. “It is written in our Constitution, Madam Speaker, but we took a step to recognize Rastafarianism as a religion in Saint Kitts and Nevis as a faith practice, or what the members who practice it prefer to call it a way of life, a faith based way of life,” he added.

A few observations re Bondi’s firing: 1) Bondi executed Trump’s retribution agenda, but the system worked and stopped these vindictive prosecutions. 2) Trump recognizes they might not have the Senate next year and they need to make changes now. More to come. 3) Trump was worried about Bondi’s oversight hearing on Epstein. 4) Bondi will not be excused from oversight next year. She has been at the center of a Trump’s weaponization of govt. 5) Will Bondi get a preemptive pardon by Trump? We know Trump is immune, but his cabinet is not.
