Cursed Units

A collection of cursed scientific units. What If? article: Dimensional analysis: Distance in astronomy: Pulsar scintillation: Background music was me improvising on a piano. Some small corrections: the distances between the planets in the graphics should be between their centres, and the wording when describing the pulse delays is backwards at one point. If you know any other cursed units, share them in the comments! Here’s some more (look for the hearted comments to see the original posts)... Noise in a voltage signal is measured in V/√Hz (volts per square root hertz). You would expect the amount of data produced by a particle collider over a time period to be measured in bytes or number of collisions, but apparently it’s measured in fb^-1, inverse femtobarns, a barn being roughly the cross-s
