Physics on the BattleField: The Night Vision Goggles in Narcos

The series has gained an international fame from the first season. Narcos is a very popular American TV series produced and distributed for Netflix. The show tells the story of Pablo Escobar and, in the third season, focuses on the empire of the Cali cartel.

The mission must be carried out in the jungle and Peña's soldiers are forced to use night-vision goggles to detect enemies hidden in the bushes. Let's analyze how these sensors can detect the presence of people and animals, even if hidden by walls! Any hot object emits characteristic thermal radiation. For ease, we consider the radiation emitted by a black bod

The Physics of a Journey: Time in Interstellar

Interstellar is the famous film by Cristopher Nolan, released in 2014. It was a great success thanks to the amazing plot and the extraordinary interpretation of Matthew McConaughey, all glazed by the emotional soundtrack produced by Hans Zimmer.

His specialty are the free kicks, the curse of goal keepers. Not surprisingly, Pirlo's free kick has been defined: "La Maledetta" (the Cursed Free kick). Andrea Pirlo, nicknamed the Football Master Let's analyze the physics of this football prowess. La Maledetta is a type of trajectory that Andrea imparts to the ball. The ball, in fact, suddenly lowers, after the barrier, and tricks the goalkeeper. How does he manage to make the ball bend in this way? Another Master offers us the answer we are looking for. The Bernoulli equation shows that by increasing the velocity of the air particles, the pressure exerted on the lower surface of
