How Ida and Tony Solved the Puzzle
|I have to admit I almost gave up. I was lost between barometers and
thermometers, a combination of both and all other weather-related
devices. Then, plain and simple observation without any searches
brought the answer. I started thinking, what would need numbers
from 1 to 11 and also from 1 to 60...Duhhhhh
Funny thing is, I googled "fluid based clocks" and most of the
answers were about cleaning fluids for mechanic clocks, so I had to
take the "cleaning" out and I saw that the proper name was "water
clock". Searching specifically for it brought me to the Wikipedia page
that holds all the answers.
I tried a different approach to this picture. I tried just looking at the
picture without looking at the questions.
When I saw this picture I was reminded of the quizzes which had
similar types of glass devices which measured pressure and
temperature. At first I just tried some general searches like "glassware
with blue liquid" which turned out to be too general. So I looked more
closely at the "numbers" and it dawned on me that it measured time
so it was a clock.
I searched for "blue liquid in glass clock" and saw a similar picture
from wikipedia. On going to wikipedia, I learned that it was a water
clock (or clepsydra) which had been developed by Bernard Gitton.
On searching images for "Bernard Gitton clock" I came upon the
above image which was located at indiansinkuwait.com. This site
gave a very good description of how the clock worked. This
particular clock is the only water clock in the Gulf. It is located at the
Souk Sharq Mall in Kuwait City, Kuwait, and is an inflow water
clock. After finding this information I looked at the questions.

|I'm risking being tardy again in getting a properly set-out reply to you
for the latest wicked quiz. I say "wicked" because it diverted me
earlier in the week from things I should have been doing. Not
because of the questions you asked, but because of those you didn't.
Working out what I was looking at (after initially being flummoxed)
was not the problem. The problem was understanding how it
worked. "What is the go of it?" (to quote James Clerk Maxwell) is
what sends us to physics in the first place, n'est-ce pas?
Just in case you haven't already happened upon it, those answers are
along with a really cool animation at
Be sure to "cliquez ici". The result, in my experience, locks to the
time on your computer's clock and continues to sit there as an
So we don't actually have to go to Kuwait (or Indianapolis, Berlin, or
...) to see Gitton's extraordinary work in action.
Darn you Megan!
I've been sitting here totally hypnotized by this animation of the water
clock. Totally fascinating!
I've been watching it on my phone and it seems to be running too
slow. It's probably because of the refresh rate of the phone. It
started out at 9:58 - which was the correct time- but it didn't flip over
to 10 am until it was really 10:05 am. I am going to look at it on my
laptop. Maybe it will stay in synch. I'd actually like to use it as the
clock for my desktop. If the water clock runs smoothly on my
computer, I will use it to make sure my computer clock is running
- Q. Gen.
Same reaction as I had - Darn you Colleen! OK, seems that it's me
who found the hypnotic animation, but it's your fault in the first
place, you wicked woman.
I've had it running, on and off, over the last week. On my desktop
box with big grunt it keeps pretty good time. I think it depends more
on processor resources than on refresh rate. With an independent
processor it would be a great everyday clock. And yes, great minds
... I've contemplated that too.
It is indeed fascinating but I'm presently giving it a rest. He who has
his head in nonlinear dynamic systems most waking hours walked by
remarking, "Are you still looking at that clock!" Now that's a great
case of the pot calling the kettle black, don't you think?
Enough! Except to say it would be nice if I'd spelt clepsydra
correctly in what I sent earlier ...
|Noon time Time-Flow Clock by Bernard Gitton, Rødovre Centrum, DK
Marking the grand entrance to the Royal Gorge
Bridge and Park, this unique time-keeping
creation is one of only three in the world, and
the only one in Colorado. Its splashing water
cascades from bucket to bucket, keeping track
of every minute of the day.
|Royal Gorge Water Clock
It is a combination of three water-powered
clocks – a 4th-century BC Greek clepsydra, an
11th-century Chinese water wheel clock and a
17th-century Swiss pendulum clock – plus a 17-
note bronze carillon to ring the hour based on a
250-year-old design found in an old English
church. The whole assembly is mounted on a
floating pontoon that rotates every 12 hours
giving a fourth time indicator as a pointer
sweeps past Roman numerals placed in the
water around the fountain's perimeter.
