User:Quietly/mirabile dictu

Mirabile dictu is a Latin phrase meaning "wonderful to tell". This page is a list of sourced facts I find particularly wonderful. (Feel free to tell me or correct any mistakes if I'm wrong about any of this!) Also, feel free to contribute your own interesting facts, just please cite them if possible.

Miscellaneous
I plan on growing this list significantly over time, and increasing the number and veracity of sources (both internal to wikipedia and external links). Feel free to contribute!
