“How Long is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension” ...
|200 km increments|
= 2,400 kms
approx 1,491 mi
.... is a paper by mathematician Benoit Mandelbrot, first published in Science in 1967.
|100 km increments|
= 2,800 km
approx 1,700 mi
The paper examines the coastline paradox ... I leave you to check out the Wikipediaarticle ... but fractals overcome our problem ... how long is the coast, such as how long is a piece of string ...
So as you can see ... interpretation is needed as to the length ... but according to Wiki and its List of Countries by length ... the British Coast is ranked 12th or 16th:
|50 km increments|
= 3,400 km
approx 2,100 mi
12th in the World Factbook at 12,429 kms (7,723 miles), or
16th in the World Resources Institute at 19, 717 kms (12, 252 miles)
So I leave you to decide how long the coast of Britain is ... and where do you measure from: the highest cliff, to the lowest decline ... and in millimetres or tiny fractions of them, or as here in rather large increments. Defeats me!
|Borth beach, Wales - a skeletal forest: buried under|
peat, sand and salt-water more than 6,500 years
ago combed out in one of our storms
During storms the beach is combed down, and much of the underlying rock, or perhaps a buried forest, or 800,000 year old human footprints briefly appear, before sand and sediment once again cover them up ...
Fish of all varieties surround our shores ... too many to mention, but one or two ...
The plaice is an expert at camouflage, as it lives for the first few years of its life near the shore, becoming almost invisible on multi-coloured gravel.

Harbour by John Cleal - see Wiki for more details
Herrings, an eponymous British fish ... which we have fished for and eaten over time humanly immemorial ... I also wrote about them last year in my A-Z cookery theme.
|Fish and chips - thank goodness lunch is coming up!|
I could not miss out cod or hake ... our standard fare for Fish and Chips ... which we used to eat out of the newspaper it had been wrapped in, laced with salt and pepper and a sprinkling of vinegar ... not for me though ... I enjoy my batter crispy!
I would stop in Hayle (in the St Ives Bay area) on my way to Carbis Bay and my grandmother’s house with supper for us all ... having travelled down from London – the smell in the car was hard to resist!
These hollow, jelly-like animals called anemones give us beautiful coloured sea flowers: from salmon pink, to emerald green and jet black.
|Sargatia - painted by the Naturalist|
Philip Henry Gosse, 1855
They move slowly, sliding their muscular bases along the rock surface ... some burrow in sand and gravel, while others slide into crevices in the rocks ... so only their tentacles show.
Their “petals”, the tentacles, are equipped with specialised stinging cells that poison prey, which is then pulled inwards to the mouth.
That is F for fracturing Fractals, found Forests or Footprints, fruitful Fish, fluttering Flowers ... from Aspects of British Coasts ...
