You're no better educated given one episode of the nightly news than you are when given one episode of "breaking bad". In that way one isolated pop culture clickbait artifact f...

As if that weren't bad enough, the sound waves are said to reach “18 to the 12th power decibels.” What makes this particularly grate on the ear of a physicist is that the decibel scale is a logarithmic scale, like the Richter scale. This means that the number of decibels already represents a pow...
