This Is What Happens When a Physicist Reads “Goodnight Moon”
Goodnight moon, goodnight room. Goodnight frogger, goodnight super-analytical blogger.
Chad Orzel of the physics blog Uncertain Principles has had plenty of time to contemplate the beloved children’s book Goodnight Moon in the course of bedtime readings with his toddler. And he got to wondering, just how long does it take the book’s bunny protagonist to say goodnight to all the objects in the room? And could a physics blogger figure it out from eyeballing the moon’s rise through the sky during the course of the story?
Happily, yes. Go read the full post for the math of the moon’s passage through the sky; we’ll skip to the results and tell you that Orzel puts the figure at about 6 minutes. But there’s a hitch: The clocks shown in various pictures of the bunny’s room instead show that one hour and 10 minutes have elapsed. There are only two possible explanations, Orzel says:
These two methods clearly do not agree with one another, which means one of two things: either I’m terribly over-analyzing the content of the illustrations of a beloved children’s book, or the bunny’s bedroom is moving at extremely high velocity relative to the earth, so that relativistic time dilation makes the six-minute rise of the moon appear to take an hour and ten minutes.

Gr8. Victorians txted 2. B4 cells.
A message from the Victorians: “I 1 der if you got that 1 I wrote 2U B4.” Helz ya, 1800s Brit10! We got it. Though they didn’t have cellphones or their 160-character limits, phrases like this one show nineteenth century English writers weren’t above an occasional stylistic shortcut.
The line comes from the poem “Essay to Miss Catharine Jay,” part of Charles Carroll Bombaugh’s 1867 Gleanings From the Harvest-Fields of Literature. The poem will appear in a forthcoming exhibit at The British Library as an example of “emblematic poetry.”
As Discovery News reports, such shortcuts appeared even before the Victorians; for example, the phrase IOU (for I owe you) originated in 1618. Txtese abbreviations appeared in literature from both sides of the Atlantic, with Americans also writing to Miss Catharine Jay, or Miss K T J.
Perhaps the proto-texts teach an important lesson: Lopping off word parts doesn’t mean you don’t have class. Another excerpt meant for Miss Catharine Jay:
But friends and foes alike D K,
As U may plainly C,
In every funeral R A,
Or Uncle’s L E G.
