Three-Body Orbits [Gallery]

submitted by technocrit to science 68 points | 8 comments https://kottke.org/26/10/three-body-orbits There are no generalized solutions to the three-body problem. Say you have three planets orbiting each other: it’s impossible to calculate how they will move using Newton’s laws of motion and gravity. Unlike the two-body problem, the three-body problem has no general closed-form analytic solution. The differential equations that govern the motions of three gravitating bodies are not integrable and cannot be solved to give explicit formulas for the positions of the bodies as a function of time.

3D Printed Einstein-Szilard Refrigerator Cools With Fire

submitted by technocrit to science 59 points | 0 comments https://hackaday.com/2026/10/31/3d-printed-einstein-szilard-refrigerator-cools-with-fire/ They may not deliver the highest efficiency, but absorption refrigerators have earned a persistent place in camper vans and industrial plants thanks to a few distinct advantages: they can operate using waste heat alone as an energy source, and they can be quite reliable due to their lack of moving parts. It can be a bit hard to understand their working principles, though, which is why Ben Krasnow built a transparent Einstein-Szilard refrigerator.

Is It Really Possible for a Nuke to Ignite the Atmosphere?

At exactly 5:30 AM on July 16, 1945, the world’s first atomic bomb, codenamed Trinity, detonated over the desert in New Mexico, unleashing in an instant the power of 18,000 tons of TNT. The atomic age had begun. As night turned to day and a fireball 200 metres across rose into the sky, the scientists of the Manhattan Project who [...] The post Is It Really Possible for a Nuke to Ignite the Atmosphere? appeared first on Today I Found Out .

Towards LoRA science

Attribution: Nesiacel planned and executed all experiments. Analysis of the experiments was shared between the authors. Thanks to Clement Dumas for his input while we did this research. TLDR; 1)We have developed a framework for reverse engineering LoRAs trained on MLP downprojection. We posit that it's extendable to all LoRAs and welcome further research. 2) We reverse engineered a simple case of backdoored Weird Generalization 3) In this post, we discuss the four experiments that developed this framework 4) The Weird Generalization LoRAs that we studied work by connecting neurons which activa

Would you pay to have the ‘best baby’? Liberal eugenics and the troubling quest for human perfection

For decades the idea of eugenics has been taboo. Now it is returning in a new commercial guise For a very long time, I dreamed of being cured. I was born in 1981. I learned to walk early enough, but I stumbled and fell more easily than other children. My parents began to worry that something was wrong, that my muscles were weaker than they should be. Eventually, at the age of three, I was diagnosed with a form of spinal muscular atrophy (SMA). In the 1980s, the precise mechanics were not yet understood, but the condition was known to be hereditary, probably linked to a recessive gene. It was a

The Vibrant Color Wheels Designed by Goethe, Newton & Other Theorists of Color (1665–1810)

Maybe it’s the cloistered headiness of Rene Descartes, or the rigorous austerity of Isaac Newton; maybe it’s all the leathern breeches, gray waistcoats, sallow faces, and powdered wigs… but we tend not to associate Enlightenment Europe with an explosion of color theory. Yet philosophers of the late 17th and 18th centuries were obsessed with light […]

Understanding DC motor principles

A project from electroniclovers on Hackster walks through how a DC motor turns current into rotation, using magnets, a copper loop and a 3D simulation to show the steps. It starts with two permanent magnets and the attraction between opposite poles. Next, current through a copper rod makes a magnetic field around it, and reversing […]

MIT engineers design a safer, more efficient vaccination system for farmed fish

Zach Winn writes in MIT News about a team at MIT and the U.S. Department of Agriculture that built a new way to vaccinate farmed fish. Today the most effective method uses metal needles. Fish have to be sedated, lifted out of the water and injected one at a time. That’s slow and stressful for […]
