For physics geeks, Feynman fans, astronomy buffs and general science nerds (like me!). 137 is a number that will always be fine by me, at least in this specific universe.
If you or someone you know just can't resist correcting grammar and spelling (like the title above) this is the perfect gift!
Great for readers, writers, teachers, or anyone else who seeks perfection in communication.

From a Robert Frost poem, great for amateur (or professional!) astronomers, science majors, poetry buffs and teachers! This includes a detailed moon map of the Bullialdus region.
From a lovely poem by Sarah Williams (1868):
"Though my soul may set in darkness, it will rise in perfect light;
I have loved the stars too truly to be fearful of the night."
