Recently, one of my graduate students, Tom, said, "Kim, I've decided to wear a bike helmet on the way to class." And Tom knows that that little bit of foam in a bike helmet can reduce the g-force of impact by half.
Hace poco, mi alumno de la universidad, Tom, me dijo: "Kim, voy a usar casco con la bicicleta para venir a clase". Tom sabe que la poca gomaespuma del casco reduce a la mitad la fuerza G de impacto.
