Twinkle, twinkle, little nonradially-pulsating delta Cepheid
Radial equations from the analysis of convection within pulsating variable stars. You should see the nonradial equations. Stars are pretty, sure. But when you stop to think about them, they get all complicated and stuff. Image source: Astrophysical Journal Supplement Series
A friend of mine told me a story recently, and it made me laugh:
George Buttrick was a famous preacher and professor. Once he was riding on a plane and scribbling a lot of notes. The fellow next to him asked him what he was doing. Buttrick told him, “I’m a preacher, preparing Sunday’s sermon.”
“Ah, religion,” the man replied. “‘Do unto others as you would have them do unto you.’ That’s my religion. Nice and simple. That’s how I like it.”
“I see,” said Buttrick. He kept working.
Some time later he turned to his neighbor and asked, “So what do you do for a living?”
“I’m an astrophysicist,” said the man. “I teach astronomy at a university.”
“Ah, astronomy,” Buttrick replied. “I see. ‘Twinkle, twinkle little star.’ That’s how I like my science. Nice and simple.”
Happy Thanksgiving, all!
