在书里看到据说是乔治·伽莫夫或者刘易斯·理查森写的：

一闪一闪亮晶晶，
满天都是小星星，
幸好我懂光谱学，
知道你是元素氢。

想查一下原文，发现近年有人写了更扩展的版本，作者是Julia Kregenow和Jason Wright，大家可以唱唱看：

Twinkle Twinkle Little Star
I know exactly what you are

Opaque ball of hot dense gas
Million times our planet’s mass
Looking small because you’re far
I know exactly what you are

Atmospheric turbulence
Causes rays of light to bend
Blurry light gives views subpar
Causing twinkling little star

We see you as if in the past
Light’s not infinitely fast
Lookback time delays our view
I know exactly what you do

Fusing atoms in your core
Hydrogen, helium, carbon and more
With such power you shine far
Twinkle twinkle little star

Classed by their spectroscopy
Types named O, B, A, F, G…
Bright when close and faint when far
I know exactly what you are

Smallest ones burn cool and slow
Still too hot to visit, though
Red stars dominate by far
Twinkle twinkle little star

Largest ones are hot and blue
Supernova when they’re through
Then black hole or neutron star
I know exactly what you are

Gravity holds on too tight
Nothing gets out, mass or light
Black holes are the most bizarre
Remnants of a twinkling star

Neutron stars spin really fast
When their beams of light sweep past
Then we call you a pulsar
I know exactly what you are

Our Sun’s average as stars go
Formed 5 billion years ago
Halfway through its life so far
Twinkle mid-size yellow star

Sunspots look dark but they’re bright
Slightly cooler so less light
Temporary surface scar
I know exactly what you are

Swelling up before it’s dead
Cooling off and growing red
Then its end is not so far
Twinkle big red giant star
