Sci Fi Writers Have No Sense Of Scale!

This unattributed & provocatively title piece at TV Tropes is a sane look at some common misunderstood primitives in sf - distance, time, size & mass, cultural change, energy, velocity, probability, & unitless numbers.

I've only read the opening descriptions - they're accompanied with long bullet-lists of examples, making the whole document rather long.

Oops - forgot recording "via" URL. Sorry.
