In 1890, Henri Poincaré proved the non-existence of the uniform first integral of the three-body problem and the sensitive dependence to initial conditions of its trajectories.
Yet, stable solutions to it do exist and these are some of them.
Durante 30 años, la fusión nuclear tuvo un límite que nadie se atrevía a cruzar: el límite de Greenwald. Si aumentabas demasiado la densidad del plasma para obtener más energía, el reactor perdía estabilidad. Era el dogma aceptado. China decidió no aceptarlo.
El reactor EAST, su “sol artificial”, ha operado un 65 % por encima de ese límite, y lo ha hecho de forma estable. No fue un milagro teórico, sino ingeniería pura: optimizar cómo el plasma interactúa con las paredes del reactor y resolver un problema que otros habían dado por inevitable.
La lectura incómoda... mientras Europa se enreda en regulaciones, burocracia y debates interminables sobre riesgos hipotéticos, China ejecuta. Prueba. Falla. Aprende. Y avanza.
❌ Nota: no se ha demostrado todavía que esto signifique generación neta de energía útil o una planta comercializada: es un avance de laboratorio en estabilidad de plasma.
Snow squalls this morning brought significant impacts to Chicago and the surrounding area. Chicago’s airport was forced into a ground stop due to the squalls. The snow has since moved out, but delays still remain.
❄️ Ice apocalypse in Siberia
-56°C has been recorded in Yakutia — the lowest temperature on Earth right now.
