It's an interesting fact that modern professional astronomers

rarely
know the constellations. They don't need to since they just dial

in
the coordinates of the object they want to observe with their big
GOTO telescopes. Or they may not even observe themselves,
professional observers observe for them. That's rational for
optimizing the use of available observing time of course, but it
certainly make you lose contact with the skies.


Right. But contact with the skies is a luxury that amateurs can

enjoy.
The professional has work to do. Except that in my club we have a
number of professionals who are also amateur astronomers (STSCI,

APL,
Goddard are all nearby). For the most part they don't get anywhere

near
a telescope in the professional lives, but they do commune with the
skies at our star parties.


It's like if a
professional geographer didn't know where Switzerland or China or

USA
were situated without looking them up on a map, and if he wanted

to
go there, he just dialed in the geographical coordinates on the

GPS
of his self-driving car or self-flying plane and then let it take

him
there.


According to a friend of mine who is a military pilot, what the
traveling geographer really does in the modern era is board a
commercial flight where a trained pilot dials in the geographical
coordinates on the GPS of his (largely) self-flying airliner and

let it
take him where he wants to go. Barring a Lion Air-type incident,

that
is.


That's why air travel sometimes is considered to not be "real
travel". If you travel on the surface instead, you get to see much
more of the area you travel through. But of course surface travel
takes much more time, and that's time today's rushed people think
they don't have.
