How to greatly appreciate AudiogoN....

But the essence of your question lies in the definition of esoteric 

the issue with “ small number” is that it is undefined.

the law of large numbers make FEW actually a decent sized population....

I own a Cellestion Telescope which I love to use in the Summertime.  It's a fascinating universe that we live in.

     High quality in all things is very important to me.  I bought a budget transporter once and beamed down for a date on Match.com.  After dinner I went to the bathroom to take a leak and found out my nose had been transposed with my weinus during the transport process.
    It was so embarrassing, and the kiss goodnight was so awkward, that I swore I'd always go for high quality in all things from then on.  I returned the budget transporter the next day for an expensive, high quality one with very low distortion reconstruction circuitry and even an  'enhance' feature for certain body parts.  I've been very popular with the human females ever since.

The overall quality of consumer goods has improved considerably since 1900!

@roberjerman...*L*  One could hope that 120 years ought to make for improvement....

IMHO, the largest lapse in improvement is, unfortunately. Us.

The more we seem to learn, the more we apparently forget.
We keep hearing that our mental capacity seems limitless.

...and then I see a guy on the tube that shouldn't chew gum when trying to walk....'relatively speaking', all in all...

The more things change, the more they remain the same...*shrug*

WE are the enemy we ought to fear the most....mho....;)
