Sound

We couldn’t make podcasts without the science of sound. There’s a lot of technology involved in capturing the vibrations we’re making with our vocal folds so that we can share them with the whole Internet! So this week, we’re fine-tuning our knowledge of sound. Do scientists even know why music makes us feel emotions? Is the ocean really as silent as it seems, or are fish partying down there? And how did computer nerds send each other video games and Christmas cards through radio broadcasts?

Follow us on Twitter @SciShowTangents, where we’ll tweet out themes for upcoming episodes and you can ask the science couch questions!
