The three-body problem is a classic and notoriously difficult question in physics and mathematics. It asks: How do three objects, such as stars, planets, or moons, move under the influence of each other’s gravity? Unlike the simpler two-body problem, which has precise and predictable analytical solutions (like the Earth...

Yesterday at Brown University ICERM's workshop on “Agentic Scientific Computing and Scientific Machine Learning” I spoke about “Adaptive Swarms Across Scales”, making the case for scientific AI as systems that can create representations, stress them, fracture them, and enlarge the category in which future representations live. The category here is a composable and breakable working universe of science: data, hypotheses, simulations, measurements, tools, failures, figures, papers, provenance, and the transformations that connect them. Discovery happens when those transformations become executable, inspectable, composable, and capable of changing the world model they operate within. Atomistic modeling gives one category - states, forces, trajectories, observables, boundary conditions, conservation laws. Neural surrogates learn fast morphisms inside or between such categories. But discovery is higher-order: it changes which objects and morphisms are available in the first place: what variables exist, what operations are allowed, what evidence counts, what scale is active, what invariant is being preserved, and what kind of explanation the system is even capable of forming. This is scientific method as adaptive architecture: compression, stress, fracture, recomposition. Fracture matters here because it makes the logic physical: a non-commuting diagram realized in matter. The imposed load, material hierarchy, defect field, and assumed continuum description no longer map cleanly into the observed outcome. The crack is the obstruction and it identifies where the old morphism failed and where a new representation must be introduced. The physical crack and the categorical obstruction are the same event viewed in different substrates. ScienceClaw × Infinite is a machine for constructing and transforming a category of scientific artifacts. Each artifact is typed. Each operation has lineage. Each failed branch remains in the category as reusable structure. The “paper” is no longer the terminal object of science; it is one projection of a larger compositional trace, and it can be generated at any time for consumption by a human or an AI. With that the unit of scientific labor is changing. For most of the twentieth century the unit was the result (a measurement, a theorem, a synthesized molecule). It is now becoming the algorithm that produces results, and after that, the substrate of discovery itself. The static PDF is the wrong terminal object for this regime, and the role of the scientist with it. We now design algorithms that build algorithms, and eventually substrates in which such algorithms compose themselves. At that point, the scientist is no longer outside the discovery system. The scientist becomes one of the representations the system can transform. In that sense, the systems will eventually do science to us, and that is the structural consequence of the principle they are built on.

You Can Heal Yourself With Nature Movement - By moving our body we give strength to our muscles, promote blood flow and lymphatic flow enhancing the delivery of nutrients and the removal of waste products. We also create a piezoelectric effect that energises the system. Breathing - The delivery of air into the body through intentional conscious breathing is one of the most powerful modalities for nervous system renewal, mental peace and the delivery of oxygen to the body and the removal of carbonic acid buildup from the system Sunshine - It’s my belief that the more sunlight we absorb without sunscreen, the healthier we will become. A tan looks good because it is healthy and every part of your body thrives when sunlight touches it delivering blood flow as well as a high frequency and energy Grounding - Existing in connection with the earth’s electrical fields resets everything about our energy, reduces inflammation and promotes the movement of proper channels such as detox - it’s a fantastic practice to be connected to nature. Green light - When sunlight moves through trees and leaves we receive Green light by which is very healing and high in near infrared light, in fact it is one of the most healing modalities to absorb in your skin particularly if you have any abrasions or wounds - even more powerful than red light . Fresh air - The first nutrient, having fresh air that is rich in oxygen is absolutely imperative to health and you should always have all of your windows open in the house if possible when not outside. Positive thinking - Whatever you think, shall become and having and cultivating a positive mindset that intentionally brings you positive energy is one of the cornerstones to great health. You can think yourself into sickness and you can think yourself into health so choose to view the world in a positive light and so it’ll be for you.

🚨 NASA JUST SHARED THE CLEAREST VIEW YET OF JUPITER’S MASSIVE HEXAGONAL STORM AT THE SOUTH POLE. This enormous, stable vortex roughly the width of Earth has been raging for years with a near-perfect hexagonal shape. At its center is a dark, powerful cyclone surrounded by turbulent, swirling bands of gas in constant motion. The hexagon is one of the most striking and mysterious atmospheric features in the Solar System. Scientists still don’t fully understand how it maintains its sharp, six-sided structure despite the chaotic winds around it. Why this matters: • It shows that giant planets can sustain extremely organized, long-lived weather systems on scales we don’t see on Earth • The hexagon is thought to be shaped by Jupiter’s rapid rotation and deep atmospheric dynamics • Studying it helps us understand how storms and atmospheric patterns work on gas giants in general including exoplanets • Juno’s close-up observations continue to reveal new details about the depth and structure of these polar vortices The deeper implication: Jupiter’s polar regions are turning out to be far more complex and structured than scientists expected. Features like this hexagon challenge our models of atmospheric physics and show that even in the most turbulent environments, nature can create remarkably stable, geometric patterns. As we study more gas giants (both in our Solar System and beyond), these kinds of observations help us understand the limits of weather, stability, and chaos on planetary scales. How do you think something this organized and long-lasting can exist in such a violent atmosphere? Follow for more frontier planetary science and stunning space imagery.

The fascinating concept of Non-Newtonian fluids, which transition from a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.

LEONARDO, also called LEO, was built by researchers at Caltech’s Center for Autonomous Systems and Technologies. Its full name means LEgs ONboARD drOne. The idea is simple but unusual: • Build a small biped robot • Give it drone-style thrust • Use the legs for ground contact • Use the propellers for balance and lift • Combine walking, hopping and flying in one system LEO is basically a hybrid between a walking robot and a flying drone. How it was built: • Two lightweight legs • Three actuated joints in each leg • Four propeller thrusters near the shoulders • A lightweight body • Leg motors for ground movement • Propellers for balance, lift and aerial control • Real-time control software that synchronizes the legs and propellers How it walks: • The legs move the robot forward • The feet touch the ground like a normal biped • The propellers constantly correct balance from above • The robot can stay upright even in unstable situations • The thrust reduces the risk of falling during difficult motions How it flies: • The legs stop being the main locomotion system • The four propellers generate lift • The robot behaves more like a drone • It can take off, fly over obstacles and land back on its legs What makes it different: • It does not walk like a normal humanoid • It does not fly like a normal drone • It blends both systems • The legs handle contact with the ground • The propellers act like fast stabilizers • The control system decides how much help comes from the legs and how much comes from thrust That is why LEO can: • Walk • Hop • Fly over obstacles • Ride a skateboard • Balance on a slackline The key idea is walking with aerial stabilization.

The Bro Split that every young lad gets sold on looks like this.⠀ ⠀ Monday: Chest⠀ Tuesday: Back⠀ Wednesday: Rest⠀ Thursday: Legs⠀ Friday: Shoulders⠀ Saturday: Arms⠀ Sunday: Rest⠀ ⠀ And yes, Arnold did it. Arnold also took enough drugs to sedate a medium-sized country, so perhaps not the most transferable template.⠀ ⠀ The problem is simple. Each muscle here gets hit once a week. Train hard enough and you'll trigger a window of muscle protein synthesis that runs for roughly 2-3 days. After that the window closes, and the muscle fibres begin to catabolise slowly. The back half of the week isn't neutral. It's quietly eroding the growth stimulus you picked up on Monday.⠀ ⠀ Once a week is not a holding pattern. It's a losing one.⠀ ⠀ The fix is training each muscle at least twice. An upper/lower split does this cleanly.⠀ ⠀ Monday: Upper⠀ Tuesday: Lower⠀ Wednesday: Rest⠀ Thursday: Upper⠀ Friday: Rest⠀ Saturday: Lower⠀ Sunday: Rest⠀ ⠀ Same days in the gym. Every muscle getting two shots at the growth window per week instead of one.⠀ ⠀ If there's a specific muscle you want to bring up faster, glutes being the obvious example, you can push that to three times a week with a full body approach, hitting the priority muscle first in every session when you're freshest.⠀ ⠀ Monday: Full Body (glutes first)⠀ Wednesday: Full Body (glutes first)⠀ Friday: Full Body (glutes first)⠀ ⠀ More frequent stimulus. More growth windows captured. Less of the week spent sliding backwards.⠀ ⠀ The Bro Split isn't useless. It just isn't optimal. And if you're going to spend the time, you may as well spend it on something that actually works.⠀ ⠀ Minimum twice a week per muscle. Three if you're serious about a lagging group. The rest is just detail.
