These wiggles are what the world’s barometers were measuring in the wake of the Krakatoa eruption. As they wiggle, they bump into the particles next to them, which, in turn, nudge the particles next to them. Snap your fingers and you jostle the particles right next to you. hemmed in in every direction by the molecules that make up the air around us. In reality, we’re more like commuters on the subway at 5 p.m.
We all live life like we’re Maria von Trapp, swinging our arms around in an empty field. In general, our world is much more crowded than we think it is. Sound is powerful and pervasive and it surrounds us all the time, whether we’re aware of it or not. Second, just because you can’t hear a sound doesn’t mean it isn’t there. There are two important lessons about sound in there: One, you don’t have to be able to see the loudest thing in the world in order to hear it. Instead, what those places recorded were spikes in atmospheric pressure - the very air tensing up and then releasing with a sigh, as the waves of sound from Krakatoa passed through. Now, nobody heard Krakatoa in England or Toronto. Not only are there records of people hearing the sound of Krakatoa thousands of miles away, there is also physical evidence that the sound of the volcano’s explosion traveled all the way around the globe multiple times. Scientists think this is probably the loudest sound humans have ever accurately measured. At that very moment, the Indonesian volcanic island of Krakatoa was blowing itself to bits 2,233 miles away. 27, 1883, ranchers on a sheep camp outside Alice Springs, Australia, heard a sound like two shots from a rifle. Consider this piece of history: On the morning of Aug.
