In this video I make an approach to what is entropy and the second law of thermodynamics.
You might think that entropy is just an abstract concept born from math and without any physical meaning,
but in reality is something quite simple to grasp that has a big role in our mundane lifes.
Entropy is the reason we can't make perpetual machines, entropy is the origin of all inefficiencies and mother to all wastes.
