Thanks, IMO, for this very entertaining puzzle. I forgot to supply the link where I picked up the Ann Broesgard/M.B. story. Here it is.

I'll have to think about a question fo a bit. I'm in an extended night shift on the intensive care ward (the darn turning back of the clocks this night ) and have none ready. But I won't be long. Maybe there will be a lull furing the later hours.

Cheers!

O. K., I've got something.

68 cm aperture Fraunhofer
21 m focal length
130 t
Equatorial mount, double horseshoe design.

Like to observe? Make sure the handful of people having a handling license like you. And -

You'll have to find it first!

what's the question?

angular resolution?

No - The task is to find it! It's a real telescope. From the data you can see it is a pretty unusual telescope, so it should be possible to locate.

A hint: You don't need a peer-reviewd research project to get observing time. However, you will have to contend with some light pollution.

Correct!

Ok, Cairo...and away we go

Thought I'd fiddle with another riddle, Eroica. [I think you might have gotten the last one (my textbook price) correct, actually, as my constants were off just a smidgen. I'll check that someday soon.]

Allow me to ask of a ratio of two ratios,
One rather interesting, at least I say so
(though I don’t recall it said
from the little that I’ve read)

On both floors resides a jolly hostess – quite a gas..............[evanoconnor and Eroica have it at last]
A denominator to both of two objects, yet they still get past
These limits are known, and even the how,
Though one noble exception is as the sound from a cow [Wow, Eroica and evanoconnor have solved this element now (yet in the ratio it fits how?)]

To follow more closely, take the path of our hostess [adiffer here has helped us]
As this helps define the ratio of one of the mostest

So two objects, in general, you must show,
along with the ratio of their ratios.

A hint I will give, and this riddle would be neater,
if we both would use a thing called meter.

.
.
[Changes: I added Greek to cow, then removed it; purple is added when a component is solved]

Hmmmm...is it that bad?

Start with the noble exception.

[One place accuracy is unnecessary.]

Eroica, you were correct in your answer, a while back, at the $6.74 figure (based on 4300K as the surface temperature). [I used 300 million m/s for light's speed and a less accurate Planck constant] oops.

Assuming a cooperative team effort ensues, I would like to have Eroica pitch the next question, if you do not mind. However, if someone simply nails this independently, then they deserve it.

Working on it.....

Hang on for a sec (all right, time-dilate that).

\mu_o = 4 \pi x 10^-7 (units of (m kg)/(s s A A))

maybe something to do with the speed of light

noble, and gas, maybe the gas constant, 8.314472 (units of (m m kg)/(s s K mol))

That was the hint we didn't need (I think most of us copped on you were talking about mu).

Other than that, I'm at a loss.

Thanks Eroica. I was hoping that was obvious, but I had no tries at it.

Nobility has different ranks, pick the easisest and keep tryin'
(My favorite was a Disney leprechaun named Brian)

I'm using the KISS system, I think. Think of the easiest choices from a given selection.

An easier start might be your jolly hostess - a gas.

time is not needed,
if the last word is headed

if 'light' is headed, forgetting time
this just reduces to the length of a line

the astronomical length of this line becomes clear
it is just the distance light travels over one year.



NOTE: what do you think of my attempted verse?
Summing up: one light year may be involved.
1 ly = 9.4605284 × 10^15 meters
1 year = 31 556 926 seconds
c = 299792458 m/s

Additional thoughts

c = 1 / sqrt(\epsilon_o * \mu_o)


Jolly hostess, sun maybe jupiter,
by path of hostess will this invlove keplers third law??
ratio of period squared to semi-major axis cubed?
