Si el #19Sept de 1985 en la #CDMX hubiéramos tenido alarma sísmica se habrían tenido 44 seg para arribo de onda “P” y 1 min 23 seg para arribo de onda “S” ve el video que realicé de la simulación
¿Cuantas vidas se hubieran salvado?
Ahora la tenemos!! Participa #simulacro2026
Bueno, pues ya que el nuevo Casio es solar y no le hay que cambiar la batería, me he lanzado a hacerle un “hydromod”
¿Y eso qué es?
Rellenar la caja completamente de aceite.
¿Para qué?
Le da más contraste a la pantalla, mejora los ángulos de visión, permite ver la pantalla bien debajo del agua y aumenta radicalmente la resistencia al agua.
Empezamos con reloj y herramientas. Sigo.
Which branch of engineering saves the most lives per engineer per year?
A) Civil and structural (clean water infrastructure, roads, buildings that do not collapse)
B) Chemical and process (fertilisers, medicines, industrial safety systems)
C) Biomedical (pacemakers, MRI, surgical robots, prosthetics)
D) Electrical and systems (power grids, medical monitoring, telecommunications for emergency response)
The first photo of Earth taken from the moon in 1966 wasn't planned. While scouting landing sites, controllers noticed perfect view of Earth rising over the horizon and adjusted the camera on Lunar Orbiter 1 to capture the moment. This predates the more famous 1968 'Earthrise' (Apollo 8).
The global internet (all servers, data centres, network equipment, and undersea cables) is estimated to consume approximately 10% of global electricity production and weigh tens of millions of tonnes in hardware alone.
The 'cloud' is a physical object: a network of buildings, machines, and cables maintained by hundreds of thousands of engineers working continuously.
