From John D. Barrow, University of Sussex
Regarding your question “what is the difference between astronomy and
astrophysics?” (Feedback, 17 August, p 76), an American
astronomer/astrophysicist who was asked the same question replied: “I don’t know
what the difference is, but I do know that if I tell US Immigration at the
airport that I’m an astrophysicist they search my luggage, but if I tell them
I’m an astronomer they send me straight on through.”
