Hooptedoodle #361a - Home Physics Puzzle - SOLUTION

Thanks very much to everyone who sent in a comment - I've now published these against the original post - here - and am pleased with the responses.

Yes, this is all about things which float, starring Archimedes - a man who was famous in my schooldays as someone who made his life's greatest discovery when he broke wind in the bath.

The puzzle is set out in yesterday's post.

Solution:

When the stones are in the boat, they are floating - well, technically it is the boat that is floating, but the stones will push the boat down into the pool to displace an extra volume of water equal in weight to the weight of the stones themselves. This is where Archimedes comes in.

When the stones go over the side, they sink, and will now displace their own volume of water, which - since stones are more dense than water - is less than what they displaced when they were in the boat. Thus - yes, that's right - the water level on the side of the pool will go down. The only special case would be if the stones were able to float on their own (because they were pumice, or hollow, or fake stones made of wood, or because the water was polluted to an astonishing degree), in which case, of course, they would continue to displace their own weight of water, and the level would remain the same.

Once again, thanks very much for having a go. Some excellent answers, and some very good explanations of the less correct ones. Just to put an official seal on things, I was going to attempt this experiment today, but the bird bath is too small.

Hooptedoodle #361 - Home Physics Puzzle

This comes from a discussion I had with a friend on email - there is no trick to this, it is simply a bit of school physics, but I was surprised how much discussion it gave rise to. I thought I'd trot it out here - have a think about this...

A man who is working from home sets up an experiment with his children one afternoon, as part of their home-schooling. They like that kind of thing, apparently.

They place a boat in their (very small) swimming pool. The man climbs in, and takes on board a number of very large stones borrowed from the garden. When the ripples have stopped, his kids mark (very accurately) the water level on the side of the pool (not on the boat, on the pool side).

Once they have done this, the man very carefully drops all the stones over the side into the water. Again, when the ripples stop, the kids mark the water level on the pool side. We may assume that there is no loss of water through splashes, overflow, drainage, leakage or evaporation during the experiment, and that the kids can mark the level with unlimited precision.

OK then - when he dumps the stones overboard, does the water level in the pool

(1) rise

(2) fall

(3) stay the same

No prizes, obviously, just a bit of (supposed) fun. I won't publish any comments for a day or two, so as not to spoil the puzzle for anyone who cares - this will also allow me a couple of days before I have to reveal that there were no responses at all.

Splash!

WSS - More Imperial Foot

The painting is still coming along nicely. As promised two weeks ago, the next hefty batch is refurbished and finished - flags apart. Another four battalions of Austrians.

As this job continues, I'm starting to get to the rather more battered parts of the hoard (horde?), so the clean-up work becomes more substantial, and in this case I had to supply about 15% of new figures, painted from scratch. To avoid any culture shock, or obvious silliness in the line-up, I have started painting the new figures in a style which is unfamiliar to me, with black outlining, to match the originals. This is slow going, but I have enjoyed the challenge, the results are quite pleasing, and it is a good exercise for me to have to produce finished soldiers painted "in the style of" the previous owner. Certainly the new boys fit in well enough with the refurbed old ones for me to have to look carefully to tell them apart.

There you go, you see - forging antiques; my teachers said I would come to no good.

Two battalions each for the regiments of Thürheim (left) and Gschwind. Not a flag in sight, of course, but that should be sorted out in the next few weeks

Next batch of Imperialists will be another of the same size, 72 figures, and that will be Phase One finished, apart from general officers. Lots of flags to do now - the new arrivals have to wait in a lengthening queue for their flags, but I'm coming around to that. Something should happen there soon.

You can see the large command bases in the centre of each unit, with the mini-dice frame at the rear. The research team here at Chateau Foy came up with a design which would make a column 150mm long or a line 150mm wide. No reason, really, just OCD at work.

Immediate plans for what happens after Phase One are to add two battalions of grenadiers to the Bavarians, two more battalions of Austrians (blue - Baden-Baden - for a bit of variety) and a small batch of foot dragoons for the Austrians.

I'm trying to keep this painting frenzy organised, so I don't lose all enthusiasm for the task. I'm (roughly) working 6 days on, 3 days off, I limit each session to two hours max and take a lot of trouble over keeping things tidy and putting everything away at the end of a batch. I think the attic area may become rather hot for extended painting sessions as the Summer comes in, but the night shifts are good [no extra pay, though]. Radio 3 on permanently during painting hours - I've sat through more screeching sopranos than usual over the last few days, but generally very calming.

The two-hour shift rule works nicely - I also try to keep my hands off the soldiers during my days off, or else I just get distracted and fiddle about, which, overall, dampens the mojo.

Strange times, so if I can delude myself that I'm staying organised - however petty the context - I find it helps. I am not painting because I have nothing else to do, I'm painting because I choose to do so.

My thanks to Stryker for advice on painting in this style - much appreciated. Keep well, everyone - look after yourselves and each other.

Hooptedoodle #360 - Something Has Changed

I observe that a number of my recent blog posts will not display some of the images I inserted. I see this symbol instead of each blocked picture:

The picture is still in a library somewhere - hovering the cursor over the missing image shows a sub-caption with the name of a convincing-looking file name on a Blogger library - but I can't see the image itself, either as part of the published post or in a draft version if I switch to the editor. Oh yes - and I can't save it or open it as a separate link. For all practical purposes, the image has gone.

Hmmm.

I had a quick, rather nervous check back to 2011 or so, and I think my older posts are unchanged. This is something of a relief, since the status of my blog as one of The Wonders of the Modern Age would be severely compromised by having the pictures removed. Knocked on the head, in fact. The pictures which have been suppressed recently were (at a quick glance) some photos of book covers, which I nicked from Amazon's website, a couple of photos of items for sale taken from a 5-year-old auction catalogue, a photo of HG Wells playing wargames in his garden which I obtained from Google. My own original photos are unaffected, and I didn't look much further, so the evidence on which to base any heavy investigation is not extensive. However, not being easily discouraged, I have been pondering what's going on here.

I realise that the Amazon pictures are copyrighted, but my blog is not any kind of commercial venture, the photos could almost be described as promotional, since I was singing the praises of the books involved, and my readership is small (anyone over six feet in height, please excuse the generalisation). Quite apart from the fact that I don't suppose Amazon or anyone else would regard the inclusion of these photos as unreasonable use, or even be faintly interested in my activities, I am puzzled, if there has been a change, as to what that change is, and why.

Maybe this is an Apple thing? My desktop machine is a Mac, and my iPhone shows the same thing. However, my tablet, which is an Android device, shows this same NO ENTRY symbol, and they all do this on a variety of browsers, so this would appear to be down to Blogger / Google.

Hmmm.

Maybe there has been a tightening up on the use of unauthorised or copyrighted images? Since my own photos of my soldier collection and the games I play are all over Pinterest and TMP without any permission from me, and since I recently learned that I can order a mouse-mat, a mug or a poster from a company in the US which seems to offer a couple of my photos as stock designs, I can see some sense in this.

It could, of course, just be a glitch in Blogger - such things are not unknown. A number of the routine facilities which Blogger offers have stopped working for me over the last year - I think that this may not be unconnected with the fact that my principal sign-on uses an email account which is supported by a competitor of Google, but that's another story altogether.

Or it could be a change in Official Policy. They could be clamping down, in which case, as long as my entire blog is not wrecked, I have to shrug and say fair enough - probably not before time. If I've done bad things then it serves me right. [Drat]

To put this in context, I do not regard this as a free-for-all. I do try to behave responsibly in these matters - if I do anything that offends someone's rights, then it is normally accidental, I'll put my hand up and apologise, and remove the image straight away. It does happen, but not very often.

Some weeks ago, MSFoy received an email from a lady in the US, complaining that he had used a photo which was her property, without permission. I sent a humble apology and removed the photo promptly. I received a friendly acknowledgement - matter closed, I hope. What strikes me as a little odd about this is that the picture in question, which was in a blog post here some six years ago, was supplied by a library service I used until (I think) last year. For a while I owned a small publishing business - in fact I still do, though it is no longer trading - and I took out a paid subscription to an online library service which offered royalty-free, non-copyrighted images - clip art and photos - which could be used for small-distribution advertising and so on. It was not an expensive deal (as you would expect - quiet at the back, please), so I forgot all about it until maybe 18 months ago, at which point I cancelled my subscription.

OK - maybe that's all irrelevant, but the incident of the complaint seemed like something new. So perhaps Google have changed their rules? It would be possible for some algorithm to check the meta-data behind any image, and suppress it, I guess. I can see this would be constructive in the overall scheme of things. However, the algorithm will struggle with screen-capture images or scanned images, so I really just have to introduce an extra step to get round this. Save an image, display it in my Preview app and take a screenshot. Pick the bones out of that.

Anyway, this post has certainly gone on long enough, considering I am blundering around in the dark. I wondered whether anyone has had a similar experience recently, or if anyone knows if the law or Google usage has changed?

Hooptedoodle #359 - Mrs Cruickshank and her Famous Son

A long time ago, when I was quite a young chap, I bought a house in a very quiet terrace in the [legendary] Edinburgh suburb of Morningside. My neighbours were, almost without exception, elderly, and I'm not sure that the arrival of my family in the street was greeted with universal approval. I was aware that we were under surveillance for a lot of the time during those early months. There was a great deal of "curtain twitching" - it seems people knew a lot about us, though we hadn't really met anyone. They knew who came and went, they knew that I wore jeans on Saturdays, and I didn't attend Greenbank Kirk.

There are advantages in such a situation. One afternoon I took a half-holiday from work, and came home to receive delivery of a package of dinner plates. As soon as I had arrived home, the phone rang. It was Mrs Cruickshank, one of our most prominent local curtain-twitchers.

She was sorry to disturb me, but a parcel had been delivered for me that morning, and since my wife and I were not at home, she had agreed that the delivery man could leave the parcel at her house. She wouldn't normally have noticed such goings-on, of course, but she had just happened to be adjusting the curtains when she saw the van arrive. The parcel was very heavy, and could I please come and collect it?

Well, yes - certainly. Still wearing my official work suit, I went three doors down and across the road, and rang Mrs Cruickshank's doorbell. Mrs Cruickshank must have been about 80, I guess - very smartly dressed but very thin.

We introduced ourselves, and she showed me the parcel - it was my dinner plates, early, but safe enough. Mrs C offered me a cup of tea - I attempted to swerve this, but there was no way I was not getting a cup of tea, so I joined her in her kitchen, and she started looking for the necessary equipment. She opened a cupboard - no cups, but there was a cream cracker with some cheese lying on a shelf - also a sherry glass, half full, on a different shelf.

She tried another cupboard. No cups, but there was another sherry glass - also half full, in there. She was about to go for another cupboard, but I spotted a framed photo on the kitchen wall - a young man in RAF uniform, and thus successfully managed to change the subject and end the cup hunt.

The photo, it turned out, was of her son, John, who had been in the RAF during the war, and had been badly wounded. His injuries had meant that after he recovered he could not stand the cold in Scotland, so he now lived in Malta, she told me. He had been dreadfully hurt, she said, and her eyes filled with tears. I'm not very good at that sort of situation - I suspect I was even worse then. With as much good grace as possible, I offered my thanks and took my parcel home - I never did get my cup of tea, now I think about it.

Mrs Cruickshank moved away shortly afterwards - I never saw her again, Whether she went into care, or hospital, or maybe went to Malta to live with her son, I know not. But I did find out subsequently that her ex-RAF son was really rather famous. There is a short bio on Wikipedia if you would care to have a look.

F/O John A Cruickshank VC

Something or other reminded me of Mrs Cruickshank recently (no - I don't think it was the sherry glasses in my kitchen cupboard), and I had a poke around online to find out more about John. It seems he's still alive, and - if he is - he'll be 100 in about a month from now.

So there you are - a pointless tale about someone you don't know and I never met, but I'll put a note in my diary to drink a glass of something in his honour next month, wherever he is. 20th May - anyone care to join me?

***** Late Edit *****

Apparently the BBC made a documentary film about this incident in 1995 - excuse the rough pictures, but here it is, introduced by the excellent Martin Bell [The Man in the White Suit - famous war correspondent and one-time destroyer of Neil Hamilton the Sleaze-Ball...]

Pretty good actually!

Enjoy.

WSS - Things I Need to Find Out - (1) Grenadiers

The sudden arrival here of a collection of miniature soldiers for the WSS at the end of last year was partly because I had always had a (vague) interest in that time-frame for wargames, partly because such a collection had become available and, importantly, because it seemed a relatively easy way into a new period - not exactly buying a new war off the peg, but certainly getting off to a flying start.

Since then I have been busily reading and refurbing and painting - all good fun, but no games yet.

My original plan was to attempt to develop the Bavarian and Austrian armies at equal pace, so that I could start playing with them as early as possible, and develop my rules as I went along. That's what I did, with some success, for the ECW a few years ago. So for the WSS I started off like this, but it soon became obvious that I could make quickest progress if I concentrated on the Bavarians first.

Various reasons, in no particular order:

(1) The miniature Bavarian army, for some reason, was in better shape - less breakages, less paint deterioration, less men AWOL.

(2) The Bavarian army seemed a lot less complicated - less daunting - organisationally and as a painting challenge. Also, the Bavarian troops I had bought in represented just about the whole of the historical army, so there were no tricky decisions about an OOB. The Imperialist set-up is a lot more tricky, I would have to make some decisions about the OOB, to give some kind of historical context (though in fact my planned OOB has more to do with the facing colours of the existing collection!).

(3) There are some aspects of the Austrian organisation which I haven't yet got a grip on - though I am acquiring some impressive-looking books. I just have to read the beggars now.

(4) The whole subject of WSS flags is a lot more complicated for the Imperial side. This may seem trivial, but for me it isn't.

I've now reached a suitable moment for a bit of a sanity check. I have two big batches remaining of troops to refurb for the Austrians, then my Phase One plan is pretty much complete, if I can get the numbers of staff figures up to scratch. I'm due to start painting again on Thursday, and I'm not sure that painting and thinking at the same time is as easy as it used to be. There is, though, a need for me to do something about grenadiers.

So today's subject is grenadiers. How did the Austrians arrange their grenadiers? How shall I paint and base the grenadier element in my Austrian army? I'll start this by interrupting myself, and returning briefly to describe what I'm doing for the Bavarians.

Bavarian Leibregiment grenadier - plate by Anton Hoffman

Thus far, for the Bavarians, I have arranged a few grenadiers in the right-hand base of each battalion, to indicate that there was a grenadier company present, but they serve no real purpose beyond the important one of looking nice. My games are unlikely to operate at a tactical scale where the grenadier company is detached to do something specific. I still do have the job of painting up two proper grenadier battalions for the Bavarians, though. My understanding is that the Leibregiment had two battalions of fusiliers (which I have painted already), and one of grenadiers (which I haven't) - this grenadier battalion was a designated unit in its own right, wore a slightly different uniform from the fusiliers and had its own flags etc.

OK - good so far. In 1703 or thereabouts, a regiment of (supposedly) French emigrés was to be set up, organised the same as the Leibregiment. According to the autobiography of Jean-Martin de la Colonie (who had expected to be the colonel of this new unit, but eventually was appointed lieutenant colonel), the fusilier battalions were never formed, though the grenadiers certainly were, and can be found on the OOB for Schellenberg - the Boismorel Grenadiers. The inhaber, Monsieur Boismorel himself, was a Frenchman (his name, I think, is a kind of forest mushroom, which is not important at this point, but is the kind of nonsense that interests me), and his personal ambition, according to Colonie, was to stay as far from any warfare as he could. The Boismorel boys have the appeal of offering some variety in the uniforms - dark red, in this case. Some of them wore grenadier caps, some wore tricorns - a welcome bit of colour on the wargames table and - again - they were a distinct, permanent grenadier formation with their own flag.

Righto - so that's what I'm doing for the Bavarians, now, for goodness sake, let's get back to the Austrians.

Austrian Grenadier on the left - image used without permission

There was a grenadier presence in the Austrian bit of the collection I bought in, but I am intending to change it. Based on what I have established so far (which is not very much), the Austrians would group together the grenadiers from the regiments within a brigade, thus the provisional battalions formed would be separate from the fusiliers, but would not have flags, and the facings and so on would be a mixture of the contributing regiments. This is kind of familiar to me, since this is what I have tried to reproduce for my Napoleonic Spanish army of 1809.

So my first question for this new Age of Reason is, did the Austrians organise their grenadiers by brigade, in this way? Am I right in assuming that the battalions thus formed would have no flags of their own, since they were informal groupings? Which leads me on to the practical issue of how I should base such units. My Foot battalions for the WSS are organised as 3 bases of 6 figures - each base is two rows of three men, the centre base holds the command presence - colours, mounted officer, drums - while each flank base includes one officer on foot. The bases can be used to denote the formation, but they do not operate independently, and are not removed for losses.

This is now getting into thinking out loud (or in print), but if I were to combine the grenadiers from two regiments for a brigade, for example, I could have one base of grenadiers painted for each regiment (I could even include a drummer in each such base) - not sure if I need a command base, nor how such a base would be made up, but now we are getting into fiddly detail. I could make a grenadier battalion from just two such bases - I'll have a look at the numbers in the books and see if that would make sense.

At that point I think I've conveyed the nub of the problem. Beyond that I'm going to embarrass myself with my own lack of knowledge! If you have experience of the WSS on the tabletop, I'm keen to learn how you think the Austrians organised their grenadiers, and how you set this up in miniature. All ideas welcome!

If this goes well, my next questions will be about the nippy issue of Austrian flags in 1703!...

WSS - Another Batch of Cavalry

It took me three days (not very intensive days) to paint the remaining cavalry which were still in the current queue. About half that time was needed to refurbish those figures I could lift pretty much straight from Eric's collection (with facing changes and a bit of cleaning up), and about half to paint the missing command figures from scratch.

From front to rear, these are the (Bavarian) Santini Dragoons, the (Bavarian) Leib Garde and the (Imperialist) Aufsess Dragoons. Not a flag in sight, as yet. I have a good image of the flag for the Aufsess boys, courtesy of one of the Bruno Mugnai books, but have come up with nothing at all yet for the Bavarian dragoons - maybe they didn't carry them in the field? Nah - there's men with poles waiting for them, so if I can't get authentic flag images I'll invent my own. I've a lot of flags to do, so I'll have a graphic-design week later on.

The Aufsess unit (grey coats) are actually Franconian, from the Fränkische Kreis - I chose them because I had pre-painted troops in very similar coat colours - no better reason for selection could be imagined! The dismounted dragoon contingent for the Aufsess are now in the queue - I have the figures, I just have to paint them.

The Leib Garde (blue) are actually [heavy] horse; the squadron with the red belts and facings are the Carabiniers, the squadron with black are the Hartschiere.

No excuses left now - the next job must be the first of the remaining big Austrian foot batches - 4 battalions, I think. I'll clear the decks and have a couple of days break before I disappear into that lot.

I had a very pleasant walk on my own yesterday on the farm - during one of the few sunny spells of the day. I walked down to one of the farm's reservoirs - really just a big rainwater sink which they use to pipe water on to the fields. There must be fish in the reservoir - I saw a swan, about half a dozen geese and a few ducks, and a spooky heron took off as soon as I appeared. Strange creatures, herons - they take off like a lorry-load of scaffolding. I also saw and heard the skylarks busy over the farm fields, so I guess they were trying to distract my attention from their nests.

Very therapeutic, anyway.

Keep well, everyone.
