Can we synthesize a beating heart directly from stem cells? Did Dorothy’s friend, the Tin Man, have a heart? Does blood flow through the veins of computer engineers? Not yet, yes, and not until proven otherwise.
The term pulse has taken on a biological meaning in popular culture. It is used to describe the gush of blood sent streaming from the heart throughout the body. You can feel your pulse rate by pressing against your neck. Fictional characters always check the wrist to see if someone is dead, but the neck seems like a more reliable indicator (if I were a doctor using the wrist to be fancy, I would probably pronounce some living people dead).
In science, a pulse takes on a more general meaning. It is a single disturbance that propagates through a medium or material. The source of the pulse may be a beating heart, but it can just as easily be a loud horn. The loud horn creates a sound of a certain intensity, which travels in all directions through the medium of air. Sound waves may appear to be mystical, but it is just a game of broken telephone between neighbouring air molecules; information, in this case, longitudinal vibrations on a molecular scale, is being transported.
