First use of droplets was at the 1966 horizontal on 10th Sept 2019 (placemats and parameters by which made).

Image

In this DropletsCharges, there is a +20 attractive charge on Dow; -2 repelling charge on Offley; and other small charges not relevant for this calculation (+1 Cr; -3 G-2016); +1 GC). So going from Dow to a little past Offley, somewhere in Taylor’s circle, is a balance point (not quite Lagrange, nor quite a termination shock) which — for my palate — gives some intricate structure. Different opinions welcomed.

Where is this balance point? At a distance d past Offley, measured in radii, in Mathematica notation
Solve[{D[20/(d + 2)^2 - 2/d^2, d] == 0 && d > 0}, d]
That’s the real root of 9 d³ − 6 d² − 12 d − 8 = 0   ⇒   d ≈ 1.73, which is in happy optical agreement with the output.

I've never massively been a fan of these turning points, always caused me numerical nightmares. I'd be tempted to shift charges to hide it in the 'T' of Taylor's.

But we’re doing different things. You are precisely modelling something difficult. Whereas I am using a simulation of a physical process to make something aesthetically appealing.

So I disagree.

Having a quick look at this, I notice that d~1.73~sqrt(3). Do you have any insight as to why this is the case?

Coincidence: d = (1 + 10^⅓ + 10^⅔) × 2/9; d² = (7 + 4×10^⅓ + 10^⅔) × 4/27 ≈ 3.00138.

Just a thought on a small modifier you could make to this package. Consider a dipole charge structure, (i.e. a closely spaced +ve and -ve charge, perhaps hidden in some text?) and you'd have magnetic dipole field lines!

At yesterday’s ’66 horizontal some claimed that the droplets resembled a uniflagellar haploid gamete produced by a male mammal (not quite the original phrasing).

For my taste such a gamete has a very clear boundary between head and tail. This is not true of these droplets, for which the thickness is linear in the distance along central path. So I disagree, but nonetheless do not wish such thing to be falsely perceived.

One possible change would be to increase the value of the parameter DropletsOuterWidthStart.

With DropletsOuterWidthStart = 0.48, as was true for the ’66 placemats
Image


With DropletsOuterWidthStart = 1.44:
Image


With DropletsOuterWidthStart = 2.16:
Image


With DropletsOuterWidthStart = 2.88:
Image


What’s the smallest value of DropletsOuterWidthStart such that the droplets don’t appear to be sperm cells?

To me the original don't look like sperm, which have a bulbous head and long wiggly tail. I prefer the original, but if there has to be a change would vote for the smallest change tolerable. I guess those that see the shapes as sperm have a wild time with Paisley Pattern. :)

(I don't think that helps in any way, nor is likely of much interest to anyone, but I noticed it could be simplified so...)

An observation; you have chosen to replace the arrow-headed lines with small linear shapes all heading towards one or more large circles. The impression may not only be a consequence of your linear shapes. However, presumably if we can replace the arrow-headed lines with sperm-like shapes, then we could potentially use many alternatives which might generate different interpretations - ants spring to mind as an example.

Fully agree, but significantly many seem not to.

Is the surdish denominator a simplification? Maybe — tastes differ.

The intention was ‘Droplets’, which fit the drinking theme. Surely we don’t want ants on the table, nor sperm.

I'm beginning to regret mentioning this. What my comment was intended to convey is that the small part of my brain that still thinks like a 15 year old boy recognised something in this design that made him snigger. That was it really.



I believe it to be a scientific fact that all men above the age of 15 have this part of their brain.

True. My wife sighs, while my sons and I giggle. I'm a bad influence, apparently. :)

Sorry, forgot to report. The structure of DropletsCharges has been changed to overload the position specification. As before it can be an integer, a WithinPage glass number; now also allowed is an array of the form [x y], in which [0 0] is bottom-left of the page. Which allows positive and negative charges to be very close: example, with four charges arranged as two dipoles at 90° to each other, the charges within each dipole being apart by 12pt = ⅙″ = 4.2⅓mm. (Separately, note the file size is 437kb, which drops to 106kb with /Droplets false def.)

The dipole example looks really sharp. Looking forward to seeing it in some placemats.

I don’t like it as much as the examples with isolated poles. YMMV.

For those wanting something like that, I did it in a slightly complicated way — numbers could have been used instead of formulae.

Code: Select all

/Droplets true def
/DropletsCharges [  % Length a multiple of 3: SheetNum or /All; position being either, type integer, the centre of the WithinPage circle, or array [x y]; charge being numeric; perhaps repeat.
	/All  {[MgnL 0.75 mul PageWidth MgnR sub 0.25 mul add 6 sub  PageHeight MgnB MgnT sub add 2 div      ]}  -1
	/All  {[MgnL 0.75 mul PageWidth MgnR sub 0.25 mul add 6 add  PageHeight MgnB MgnT sub add 2 div      ]}   1
	/All  {[MgnL 0.25 mul PageWidth MgnR sub 0.75 mul add        PageHeight MgnB MgnT sub add 2 div 6 sub]}  -1
	/All  {[MgnL 0.25 mul PageWidth MgnR sub 0.75 mul add        PageHeight MgnB MgnT sub add 2 div 6 add]}   1
] def  % DropletsCharges

Re: Software that makes placemats

A request has come from AHB, which I paraphrase here. He was guillotining a page of decanter labels, and wanted thin grey lines between them to guide his chopping.

I have two sources of reluctance, on which comment is invited.

• The decanter labels are spread over the decanter-label page, usually A4, to be as tightly packed as possible subject to a minimum size (DecanterLabelsMaxSmallerDimension×DecanterLabelsMaxLargerDimension). But unless the page size is a fortuitous multiple of these minima in both dimensions, typically the decanter labels will be slightly further apart. This may well be further apart than the size of the business cards to the backs of which they are to be glued. So the correct place to guillotine depends on the size of the cards, not known at the time of making the PDF (and even if known, cards will typically be further apart).

• If I cut by hand, as is usual, I’m, unlikely to follow the grey lines precisely, and their remnants will be unsightly.

I could add a small grey line at the edge of the page, for those determined to guillotine precisely between. But I’m not sure that even this should be enabled by default.

Please comment.

I could show more cut lines, perhaps only short and at the edge, such that each rectangle is DecanterLabelsMaxSmallerDimension × DecanterLabelsMaxLargerDimension, lessening this problem. But not eliminating: if the useful areas of the cards that happen to be used is smaller than DecanterLabelsMaxSmallerDimension × DecanterLabelsMaxLargerDimension, this cutting would be wrong.

I agree with the second point, though understand AHB's request. Perhaps give the feature a global flag, disabled by default for those who prefer to cut without lines, but which Alex (and anyone else) can enable to use when wanted?

Thank you.

Some observations:
(1) The short lines at the top overlap and confuse with the text of the instructions. I don't think these short lines add anything so I suggest they are removed.
(2) the broken lines around each label are more complex than I had in mind — my thought was simply to put a line halfway between each label rather than creating a gutter which needs to be trimmed twice. The edge of the paper on the left hand side can be the boundary for the left-most label, a series of lines separates this label from its companions to the right with a final line indicating where to cut on the right-hand side of the last label.

Top and bottom cutting lines would continue to be needed.
(3) Is there a reason for the decanter label cutting lines to be different colours and some being bold while others are not?

These don’t print. Display only. Have you a different PDF viewer?

These short lines, ≈ 2mm, are the only relevant lines that print.
