## Demise of the cocked hat

Visible to anyone in the world

Interesting how cliches morph into phrases totally disconnected with the original. Tonight I heard ‘Beats into a cocktail’. The speaker didn’t mean egg flip, just that A was hugely better than B.

But that’s how language changes and all power to it.

It’s hot now and we complain.

But soon the snow will blow.

At the first flake, we’ll shiver and shake.

Wishing summer back again.

## Beautiful Maths Problem

Visible to anyone in the world
Edited by Richard Walker, Wednesday, 17 Aug 2022, 17:33

Problem 1358 at gogeometry [1] asked for a proof that in a regular 12-sided polygon the four diagonal shown all meet at a point. This is quite surprising; it\'s not hard to find threee diagonals the meet at a single point but four is rarer.

After playing arouind for a while I found a proof which was reasonably neat, but I had to use sines and cosines at one point, and I'd hoped for something simpler; and there was nothing very illuminating about my proof in any case. Stan Fulger came up with something much more insightful. Here is his beautiful answer.

It uses two well-known facts about triangles.

The altitudes of a triangle, i.e. the lines drawn from each vertex at 90° to the opposite side, meet at a point.

The angle bisectors of a triangle, i.e. the lines which divide each angle in half, meet at a point.

For example

Now for a "look and see" proof.

In the picture below three diagonals are angle bisectors in the blue triangle, so they meet at a point. Also three diagonals are altitudes of the orange triangle and therefore meet at a point. Two of the diagonals are both a bisector in one triangle and an altitude in the other. Therefore all four diagonals meet at a point.

I drew the figures above using GeoGebra classic.

## Word of the day - Marshal

Visible to anyone in the world
Edited by Richard Walker, Sunday, 14 Aug 2022, 23:13

You can marshal an argument, or you might be a marshal in a sporting event, or you might be a Field Marshal, and there are many other usages but they generally are to do with organising or leading some activity.

Where does the word descend from? Well rather amazingly it originally meant someone who looked after horses. It's from early Germanic *markhaz "horse" + *skalkaz "servant". The asterisks indicate that these words are not actually attested - we don' thave them written down anywhere, so the exact words are a guess. But the first element is like "mare" and a word "scealc" appears in Old English.

The word came to us from Norman French and the French for a farrier (a smith who shoes horses) is still "maréchal-ferrant".

To conclud, here is a rather nice quote from an early printed book, courtesey of the OED.

1474   W. Caxton tr. Game & Playe of Chesse (1883) iii. ii. 85   All maner of werkemen, as goldsmithes, marchallis, smithes of all forges.

Thanks also to RobWords for his excellent YouTube video on military titles.

I bought some drops for removing earwax. They contain Urea Hydrogen Peroxide...

So you are literally putting urea in your ear.

## Climbing Plants

Visible to anyone in the world

In my garden I’ve got quite a few climbing plants.

Cultivated: Roses, Runner Beans, Sweet Potato, Nicotiana

Wild: Bindweed, Ivy, White Bryony, Blackberry

I’ve always marvelled at climbers and there’s a famous Flanders and Swann song containing the lines

﻿The fragrant honeysuckle spirals clockwise to the sun,
And many other creepers do the same.
But some climb anti-clockwise, the bindweed does, for one,
Or Convolvulus, to give her proper name.﻿

So today I was thinking about climbers and a bit of research came up with this wonderful summary. See what you think.

## Word Of The Day

Visible to anyone in the world

lachsschinken: A kind of cured, salted, smoked ham originally from Bavaria. The name derives from the German lachs  + schinken = ‘salmon ham’, from the bright pink colour of the meat. I found the word from today’s Word watch in The Times and what impressed me was the consonant cluster ‘chssch’ in the middle.

This beautiful flower is a sweet potato. I did not realise that the plant is a vine, related to bindweed and morning glories. Like morning glories each flower lasts only a day.

## Topsy-Turvy

Visible to anyone in the world

Following my earlier post about CHECKBOOK, I wrote a Python program to find dictionary words with the property they have symmetry about a horizontal mirror line; if you invert them, they remains the same. I used the UK Advanced Cryptics Dictionary, by Ross Beresford (240732 words) as my word source.

Here is the full list of then 352 results. As you might expect some of the words are a wee bit obscure.

['B', 'BE', 'BECK', 'BECKED', 'BED', 'BEDDED', 'BEDE', 'BEDECK', 'BEDECKED', 'BEDIDE', 'BEE', 'BEEB', 'BEECH', 'BI', 'BIB', 'BIBBED', 'BIBCOCK', 'BICE', 'BICKIE', 'BID', 'BIDE', 'BIDED', 'BIKE', 'BIKED', 'BIKIE', 'BIO', 'BIOCIDE', 'BO', 'BOB', 'BOBBED', 'BOBBIE', 'BOCCE', 'BOCHE', 'BOCK', 'BOCKED', 'BOD', 'BODE', 'BODED', 'BODICE', 'BODIED', 'BOH', 'BOK', 'BOKE', 'BOKED', 'BOKO', 'BOO', 'BOOB', 'BOOBED', 'BOOBOO', 'BOOBOOK', 'BOODIE', 'BOODIED', 'BOOED', 'BOOH', 'BOOHED', 'BOOHOO', 'BOOHOOED', 'BOOK', 'BOOKED', 'BOOKIE', 'BOX', 'BOXED', 'C', 'CEDE', 'CEDED', 'CEDI', 'CEE', 'CH', 'CHE', 'CHECK', 'CHECKBOOK', 'CHECKED', 'CHEEK', 'CHEEKED', 'CHI', 'CHIC', 'CHICH', 'CHICHI', 'CHICK', 'CHICO', 'CHID', 'CHIDE', 'CHIDED', 'CHIK', 'CHOC', 'CHOCHO', 'CHOCK', 'CHOCKED', 'CHOCKO', 'CHOCO', 'CHOICE', 'CHOKE', 'CHOKED', 'CHOKO', 'CHOOK', 'CHOOKIE', 'CID', 'COB', 'COBB', 'COBBED', 'COCCI', 'COCCID', 'COCCO', 'COCCOID', 'COCK', 'COCKED', 'COCO', 'COD', 'CODDED', 'CODE', 'CODEBOOK', 'CODED', 'CODEX', 'COED', 'COHO', 'COHOE', 'COKE', 'COKED', 'COO', 'COOED', 'COOEE', 'COOEED', 'COOK', 'COOKED', 'COOKIE', 'COX', 'COXED', 'D', 'DEB', 'DEBBIE', 'DECCIE', 'DECIDE', 'DECIDED', 'DECK', 'DECKED', 'DECKO', 'DECKOED', 'DECO', 'DECODE', 'DECODED', 'DECOKE', 'DECOKED', 'DEE', 'DEED', 'DEEDED', 'DEEK', 'DEICIDE', 'DEID', 'DEKKO', 'DEKKOED', 'DEO', 'DHOBI', 'DI', 'DIB', 'DIBBED', 'DICE', 'DICED', 'DICH', 'DICK', 'DICKIE', 'DID', 'DIDICOI', 'DIDO', 'DIE', 'DIEB', 'DIED', 'DIKE', 'DIKED', 'DIODE', 'DIOXIDE', 'DIXI', 'DIXIE', 'DO', 'DOB', 'DOBBED', 'DOBBIE', 'DOBCHICK', 'DOC', 'DOCK', 'DOCKED', 'DOD', 'DODDED', 'DODO', 'DOE', 'DOEK', 'DOH', 'DOO', 'DOOB', 'DOOK', 'DOOKED', 'E', 'EBB', 'EBBED', 'ECCE', 'ECCO', 'ECHE', 'ECHO', 'ECHOED', 'ECHOIC', 'ECO', 'ECOCIDE', 'ECOD', 'ED', 'EDDIC', 'EDDIE', 'EDDIED', 'EDDO', 'EDH', 'EE', 'EEK', 'EH', 'EHED', 'EKE', 'EKED', 'EO', 'EX', 'EXCEED', 'EXCEEDED', 'EXCIDE', 'EXCIDED', 'EXE', 'EXODE', 'EXODIC', 'H', 'HE', 'HEBE', 'HECH', 'HECK', 'HEED', 'HEEDED', 'HEID', 'HEIDE', 'HEX', 'HEXED', 'HI', 'HIC', 'HICK', 'HICKOK', 'HID', 'HIDE', 'HIDED', 'HIE', 'HIED', 'HIKE', 'HIKED', 'HO', 'HOB', 'HOBO', 'HOBOED', 'HOC', 'HOCK', 'HOCKED', 'HOD', 'HOE', 'HOED', 'HOH', 'HOI', 'HOICK', 'HOICKED', 'HOIK', 'HOIKED', 'HOKE', 'HOKED', 'HOKI', 'HOO', 'HOOCH', 'HOOD', 'HOODED', 'HOODIE', 'HOODOO', 'HOODOOED', 'HOOK', 'HOOKE', 'HOOKED', 'HOX', 'I', 'IBEX', 'IBO', 'ICE', 'ICEBOX', 'ICED', 'ICH', 'ID', 'IDE', 'IDO', 'IKE', 'IO', 'IODIC', 'IODIDE', 'K', 'KEBBIE', 'KEBBOCK', 'KEBOB', 'KECK', 'KECKED', 'KED', 'KEECH', 'KEEK', 'KEEKED', 'KEX', 'KHOIKHOI', 'KIBE', 'KICK', 'KICKED', 'KID', 'KIDD', 'KIDDED', 'KIDDIE', 'KIDDIED', 'KIDDO', 'KIKE', 'KIKOI', 'KO', 'KOB', 'KOBE', 'KOI', 'KOODOO', 'KOOK', 'KOOKED', 'KOOKIE', 'O', 'OB', 'OBECHE', 'OBI', 'OBIED', 'OBO', 'OBOE', 'OCH', 'OCHE', 'OD', 'ODD', 'ODE', 'ODIC', 'OE', 'OH', 'OHIO', 'OHO', 'OI', 'OIK', 'OK', 'OKE', 'OKED', 'OO', 'OOH', 'OOHED', 'O', 'OX', 'OXHIDE', 'OXIDE', 'X', 'XEBEC', 'XI']
