HAZ CLICK AQUÍ PARA VER EN ESPAÑOL When things don’t turn out as we expected there is always somebody that says: “that’s Murphy’s law”… because, according to this law, if anything can go wrong, it will. Where does this idea come from? Edward Aloysius Murphy was an aerospace engineer. It was in 1949 when his assistant connected all the electrodes of a safety-critical system wrongly, so all the measures were wrong. Since then, this pessimistic law shows up every time it rains… because there is always somebody who washed his car or the windows the day before But all the bad luck we claim to be Murphy’s has a scientific explanation. Science behind Murphy’s law You may think things never come out the way you want, but that’s because you picture an ideal, perfect, unique and therefore...
What if everyone jumped at once? When you jump nothing seems to happen to the Earth… but what if, you gather some friends, and what if, you were so nice everybody literally like you and wish to meet you just for the experiment of jumping together. There are tons of us! we share the planet with 7 billion other people, so… what would happen if we met with literally everybody to jump at once? First things first… where should we meet? Where do we all fit? If the whole humanity lived with the same density there is in New York we could fit in the Iberian Peninsula. If we stood shoulder to shoulder we could all fit into an area the size of London. So ok… let’s imagine we all meet in London and jump together. My...
Does Turning Fluorescent Lights Off Use More Energy Than Leaving Them On? It’s usually said that letting the fluorescent on when you are leaving the kitchen only for a few minutes saves energy. Is this true? Turning a fluorescent light on requires more energy than keeping it on. The energy used during to turn the fluorescent on equals 23.3 seconds of regular use. So, in terms of energy letting the lights on pays off only if you are Fernando Alonso and you left the kitchen in order to change the tires of your F1. Other lights need even less energy in comparison: Switching.on Time on (seconds) Incandescent bulb 0.36 Compact fluorescent 0.015 Halogen bulb 0.51 LED bulb 1.28 Fluorescent tube 23.3 But you may be thinking, what about the wear and tear of the fluorescent tube?...
CLICK HERE TO READ IN ENGLISH Cuando las cosas no salen como esperamos siempre hay alguien que dice “eso es la ley de Murphy”… porque según esta ley si algo puede salir mal, saldrá mal. ¿De dónde ha salido esta idea? Edward Aloysius Murphy era ingeniero aeroespacial y enunció su ley en 1949 cuando su asistente conectó absolutamente todos los electrodos de un arnés para medir los efectos de la aceleración al revés, de modo que todas las medidas daban cero. Desde entonces esta ley pesimista aparece como explicación popular cada vez que llueve de la mano de todos aquellos que lavaron el coche o los cristales de las ventanas el día anterior. Pero todos los sucesos inoportunos que le achacamos al pobre Murphy tienen una explicación científica detrás. La ciencia detrás de la ley de...
