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

@board 问一下大家有没有从事药品相关行业的。
家里老人长期吃一些心脑血管相关的药物，像金纳多、立普妥之类的。之前都是老人自己买，能在药店买齐种类，今年因为行动不便一般就是我们小辈去买。
结果哪家药店都不好买，都只卖一两盒，每次问都说是没库存了，有时候完全不卖。有次我爸急了就说家里老人买就有，自己来买没有。药店确认了吃药的人是我外婆之后，就有药了。我外婆也说她们老太太圈里，自己去买就能买齐，都买到。
整个事情给人感觉特别诡异，只直接卖给老人总感觉里面有骗局。但查码之类的也看不出什么，所以想问一下大家有没有什么相关内幕可以解释这种现象。
