Quantum tunneling is a phenomenon where an atom or a subatomic particle can appear on the opposite side of a barrier that should be impossible for the particle to penetrate.  6, record 1, English, - quantum%20tunnelling

Imaginons un électron lancé contre un mur. Si le mur est épais, l'électron rebondit, ce qui paraît normal. Mais l'électron est quantique et se comporte comme une onde. Si le mur est très fin, l'électron peut se retrouver des deux côtés du mur à la fois, ce qui parfois lui permet de passer au travers. C'est l'effet tunnel, un des effets au cœur des nanosciences.  2, record 1, French, - effet%20tunnel

Speed up effects: Tunnel effect. If you push an ordinary bicycle air pump, ... you will notice that the air leaving the nozzle moves much faster than the speed with which you are pushing. The reason, of course, is that the nozzle is much narrower than the cylinder in the pump. If you take a walk between tall buildings, or in a narrow mountain pass, you will notice that the same effect is working: the air becomes compressed on the windy side of the buildings or mountains, and its speed increases considerably between the obstacles to the wind. This is known as a "tunnel effect." So, even if the general wind speed in open terrain may be, say, 6 metres per second, it can easily reach 9 meters per second in a natural "tunnel". Placing a wind turbine in such a tunnel is one clever way of obtaining higher wind speeds than in the surrounding areas.  4, record 2, English, - tunnel%20effect

Efecto túnel. Si tomamos un camino entre dos edificios altos o en un paso estrecho entre montañas observaremos que el aire al pasar a su través se comprime en la parte de los edificios o de la montaña que está expuesta al viento, y su velocidad crece considerablemente entre los obstáculos del viento. Esto es lo que se conoce como efecto túnel.  3, record 2, Spanish, - efecto%20t%C3%BAnel
