Of course you can represent a phase space in polar coordinates, too.
It's still two dimensions, and the abstraction says nothing about the
mechanical arrangement.

In my shower, I called it "lift", the flow regulation is in fact by
rotating the same handle around another, perpendicular axis (but only in
a range of about 45 degrees).

At a remarkably cheap place I stayed in Tokyo, the device that handled
the coins was broken, so it could only handle one coin at a time, which
gave you about one minute. Then you had to get out and back. Also, it
was the only shower in a facility that wasn't gender-separated, and it
was next to the breakfast room, with little separation. But then, the
whole place was a "gaijin house", i.e. only for foreigners, and they
don't know shame.

Shower stalls are usually engineered to be less slippery than bathtubs,
but it's only a difference of degree. My mother had a bad fall in the
shower where she hit her head on the tiled wall and passed out for a
moment.

That was in a bathroom that had been remodeled ca. 1965, in the house
where I grew up. The shower stall in my condo, built 2003, is all molded
plastic. That changes the safety situation greatly. The bathtub is
plastic, too.

The bathtub in my apartment, too, and for showering, of course I stand
on a mat, but it still has a tiled wall next to it. If getting into the
bathtub is a safety concern, then this bathroom may not be for you. I
step onto the rim of the bathtub every day in order to open or close the
window. Although a 6 ft. person could probably reach it standing in
front of the tub.

It was about Richard III, so not terribly off by era, but it was still
obviously the answer one gives when one knows we're looking for a king
of England, but isn't sure which one.

I was able to answer this one, because it was about his reburial a few
years ago, so it was more a news question than high school history.
House of York was mentioned in the clue, so knowing that RIII was York
and HVIII was Tudor would make the latter unlikely.

There are voles in North America. Maybe only in the West. I know them

So you guys really think I can't recognize a stopped-up drain? Sheesh.

Remember that the size of the pipe is only part of the equation: the
water is fed into the shower head under considerable pressure, provided
either by an elevated system source or by pumps or by both, and it
flows out of the tub under the pressure of the depth of the water in
the tub.

My exasperation with the offending shower control is generated in
hotels like the Residence Inn in Mesa, Arizona, and it involves the
most acceptable temperature being at or near maximum input volume. And
as Quinn noted, this sort of performance is encountered in locations
with a perpetual water shortage.

At home, my ideal shower rate is at about 1 gpm. The maximum flow from
the spout is about 4 gpm, and in 30 seconds the water will reach the
far end of the tub and a depth of 1 inch at the drain end. It will
take 2 1/2 minutes to drain, which is no record but definitely not
plugged and comparable to other tubs I've experienced.

[the spout provides little to no restriction; you might expect the
maximum flow rate of the show to be somewhat less, but the spout effect
is easier to measure quickly.]

Imagine the depth after 5 minutes.

Yes, Tony, I am the type of nerd who measures things. Every day, in
many activities. I have a record of at least 15 months of my daily
temperature (oral or forehead). I have my gas mileage for at least 3
cars. I have the mileage of my commutes, including waypoints and
alternate routes. And there is more.

In our bathroom - and I believe this is typical - there's a place to
hang the shower head so that it acts just like a fixed shower head. You
leave it there for most of the operation, and take it down only when needed.

The place where it hangs can be adjusted vertically, which allows for
people with different heights, and for those who don't want to get their
hair wet.

WIWAL our next-door neighbours were forever wanting to borrow sixpence
for the gas meter. They never paid it back.

Most gas consumers paid their bill monthly, or perhaps it was
three-monthly. The coin-operated meters were installed only for people
who had a record of not paying their gas bills.

The most recent experience with a shower stall in a hotel room, also in
Arizona, was a tiled surround, floor, and threshold/barrier (about 4"
high; constructing one was demonstrated in a tubularEwe I found during
the walk-in-tub thread). There was in addition a shower curtain. It
was impossible to keep the water from splashing beyond the threshold;
not a problem for the outer floor, also tile, but it made a mess of the
bathmat.

The showerhead-on-a-hose I added to my wife's bathroom is a two-part
unit. Part 1 screwed onto the pipe stub. Part 2 is the showerhead
with a magnet where it attaches to Part 1.

She doesn't have to fiddle about fitting it into a holder or removing
it from the holder. She just reaches up and detaches or attaches and
the magnet holds the parts together. If she doesn't detach, it
functions as a fixed head.

Not speaking for the rest of those following this thread, but I am
willing to accept that you often stand in ankle-deep water.

Personally, I think you have emit some weird magnetic field that
causes constrictions in the drainpipes of the showers you enter. I'll
keep shtum on this in future posts lest you think that I am
irritating.

Is there something you're not telling us? The only other person I

More important to me is that when getting out of a shower stall you
don't have to step over the side of the tub which can be very
dangerous.

On mine the attachment point is connected to a vertical rod. The
vertical rod is the thing that allows the height to be adjusted. Most
people, I think, set the height just once and leave it there, but the
up-and-down adjustment allows a tall person and a short person to use
the same shower.

It's a bit like this example:

To give you that URL I had to remove a lot of tracking information.

Excellent! They are one line. Is it one knob too?

I've never been much of a plotter, or a phaser either, come to that.

Surely not alone. We have voles where I am, and the distance is not too
great for a brave little rodent.

No, in Central Canada too. I know because one of my dogs used to like
to take one along on walks, its little tail hanging out the side of his
mouth. I think it was PaulW who first clarified the definition of
"vole" for me here, many years ago.

No. Wasn't that clear from my description? "lever", "knob", qv.

I would have expected your job to require a certain amount of
visualization skill.

I turn off the water once I'm wet, and turn it on again only when I'm
ready to rinse off; I use luke-warm water, not hot, and don't bathe
quite every day, since I live alone. Let the world content itself with
that.

"Wer-ald", the age of man. The planet will go on, and life will
persist, but we and the life we evolved with are for it, IMO.

(That etymology casts some doubt on the idea that "man" meant humans in
general and "wer" meant male humans.)

There was a corridor in the American Museum of Natural History lined
with waist-high displays (so eye-level for children) of "all the mammals
native to New York State." That was where I was introduced to shrews,
a long, long line of awful little clumps of brown fur side by side. I wonder
whether they were supposed to be different species, or they were just
showing what museum displays were like before they came up with the
idea of habitat dioramas -- some of which are now a century or more old,
though they are carefully maintained.
