Walking in the park,I found large stand of hemlock that were just magnificent in a malevolent way.

While I'm in the mood for tabletop photography, here are some ghosts of "Napier's Bones"...

Stop Press. After the initial upload I found a fascinating resource, International Slide Rule Museum (ISRM). There I learned four things that amazed me.
1) 2022 is the 400th anniversary of the invention of the slide rule by William Oughtred!
2) ISRM indicates that 1901-1902 Nestler models were stamped on the slide cavity with just the manufacturer's initials, AN, plus a design patent number. My grandfather's rule here clearly shows that. So it is now identified as a Nestler, and about 120 year old. It might be quite rare. It is longer than the maker's 10" rules, and shorter than their 20" models, yet it has the same graduation density as the larger ones. I haven't yet seen any the same. (See also last paragraph below, and images in comment thread.)
3) Various web sites claim that the German rocket scientist Wernher von Braun acquired in the 1930s two Nestler slide rules, the only ones he ever used, including while heading the NASA Moon landing program. Albert Einstein is also claimed to have used these rules. They must have had a stellar reputation!
4) In my youth I'd believed that Faber-Castell was the only brand, yet one of the favourites of the ISRM was made in my home town of Melbourne, and I had never heard of the maker!

On acquiring one of the first scientific calculators available, someone in my wife's family ceremoniously flung his slide rule into the rubbish bin. But I was sad to see them slip ignominiously, from ubiquity in technical computation settings, into museum status. (My wife recovered that rule and it is in this image.)
I remember when, as a schoolboy, I unwrapped my first model, and, using only its own scales and cursor, immediately fell to verifying a hunch that its principle was based on logarithms. "Duh!", anyone with a maths background might say. But at the time, I felt that I had cracked a code and let myself in on an esoteric language that was openly inscribed in runes on this magic wand, yet which had been hiding from me in plain sight all along.
I have lost that one, which had scales on both sides, a Faber-Castell Darmstadt 2/82 -- but the one nearest the top of the frame here is a grander version of that. This latter was the most sophisticated I ever owned (with a useful πX scale), and it was made right at the end of the ready availability of these devices locally. But I hardly ever used this replacement because I only bought it in case I'd never get another chance. To me, they were and still are strangely beautiful so-called "objects of virtu". They are the very physical manifestation of that wonderful abstraction of the human mind, logarithms. (Something remarkable and elegant is vital to the practicality of a slide rule, although it can be conceptualised in other ways. Since the full scale length represents log(10), any internal position X must divide the scale length in the ratio log(X):log(10/X). That enables both multiplication and division to be performed with either left or rightward slide shifts as appropriate, and so allow a single decade to suffice -- but at the cost of requiring users to keep track of the decade they are notionally in.)
The rule lying diagonally above the others here was the first I ever knew, as a small intrigued boy, long before I understood what it was for. It has lost its (glass) cursor, while some of the scales have peeled away from the wooden substrate. Because the material looked and flexed like the struts in my mother's corsets, I always assumed it was whalebone! The device had belonged to my maternal grandfather, who had been a civil engineer in Austria. He might well have used it in calculations required for a bridge he built over the River Inn (see a very early comment below). My mother and I tried to see that in 1996, but it had already been consigned to a rubbish bin for bridges... Tempus fugit.
I have completely forgotten everything about using a slide rule..in pre computer times we used them all the time at school...this was Mrs Nahpro' s I think..

Happy Sliders Sunday - HSS!
This night vision windshield & camera lens were well worth the money. Eliminates any need for street & headlights. :0)
Harvey Scowcroft collection. This slide is very badly damaged, I have done my best to restore the mould that has set in on it
i did so much to this, or rather, had so many versions, i can hardly remember what i slid. i know i boosted blues and greens, took out some other saturation and contrast, did some masking and softening in general, added a little lens vignetting, but i really have my strobes to thanks…strobist info: television to the right, lol!
below is the REST of this glorious hat (plus some cool light reflection effects around my eye!), and the sooc original.
So BAM! and Happy Sliders Sunday, friends!! Hit L! :)

High Rock Hideaways
Hocking County
Last month my wife and I took a much needed vacation with our pup Maggie to Ohio's Hocking Hills region. We stayed at a cabin at High Rock Hideaways located not far from Ash Cave. A recent post I had seen in the Hocking Hills group intrigued me when I saw that the property boasted 9 waterfalls on their own trails. Booked. Our first day there Maggie and did some exploring on the trails so I could get a feel for the area but some light drizzle had me thinking we better return and it was a good idea. Within 15 minutes of arriving to the cabin it was raining. The next afternoon I headed out to explore these waterfalls more closely. The first falls I visited was called The Slide. Arriving at the top, it was a steep cascade waterfall that dropped at least 40 foot into a mini slot canyon. While standing there I noticed an undocumented arch in the cliff opposite the falls. Going to take a closer look at the arch I discovered a manageable scramble downstream from the falls. The scramble took me past two more waterfalls which were not really worth shooting. Once in the gorge I had to do some creek crossings and then a short scramble up the base of the falls which was a short dog leg to the main drop. Wow! I couldn't believe my eyes! Hands down one of the regions prettiest waterfalls and was the icing on the cake of a great trip with my wife and pup!

Seen at the Pinery Market some time ago, in 2016.
This is a lovely mostly outdoor market & shaded for the most part by many pine trees. It offers outdoor dining...hamburgers or hot dogs & fries or onion rings & very clean washrooms which is a big plus in my book.
"Theodore Too" comes to life in Erieau, Ontario! :0)
What is the story behind Theodore the Tugboat?
It started with a bedtime story that Andrew Cochran, the creator of Theodore Tugboat, told his son. A story about the boats in the big harbour and how they interacted with everyone. Later, these bedtime stories became the inspiration and basis for the original television series, Theodore Tugboat.

I wish I had a timeframe on this one. Just another in the sea of scanned slides.

A wonderful Soo Line scene with no information on the slide mount other than a dater.
From a digital scan from my personal slide collection.
Admired and captured this sideboard at the Central Museum Utrecht and experimented with sliding the original into a decent black and white.
This marvelous piece of furniture was designed by Rietveld in 1919.
