The Buttermilk Bend Trail seems to move from away from following along the South Yuba River. But, it is only a temporary divergence as the trail heads off to a small wooden bridge that crosses French Corral Creek before it proceeds back to meandering along the river.
The Lorenz attractor is, without a doubt, the emblematic figure of chaos theory and probably one of the most popular mathematical figures. It was at the beginning of the 60s when the mathematician Edward Lorenz discovered in his laboratory at the Massachusetts Institute of Technology in Boston that small variations in the initial conditions of a system of differential equations that simulated the state of the climate in a certain region, produced large divergences in the results. What he had discovered is what later became known as the "Butterfly Effect": a flap of a butterfly's wings would be enough to trigger a cyclone. The Lorenz attractor is the representation in space, through numerical methods, of the solution curves of the system of three differential equations with three variables studied by Lorenz.
This is a photograph showing the Lorenz attractor generated with a simple code from the free software Octave.

The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread raptor, and one of the most widely found bird species. In fact, the only land-based bird species found over a larger geographic area is not always naturally occurring, but one widely introduced by humans, the rock pigeon, which in turn now supports many peregrine populations as a prey species. The peregrine is a highly successful example of urban wildlife in much of its range, taking advantage of tall buildings as nest sites and an abundance of prey such as pigeons and ducks. Both the English and scientific names of this species mean "wandering falcon," referring to the migratory habits of many northern populations. Experts recognize 17 to 19 subspecies, which vary in appearance and range; disagreement exists over whether the distinctive Barbary falcon is represented by two subspecies of Falco peregrinus, or is a separate species, F. pelegrinoides. The two species' divergence is relatively recent, during the time of the last ice age, therefore the genetic differential between them (and also the difference in their appearance) is relatively tiny. They are only about 0.6–0.8% genetically differentiated.
While its diet consists almost exclusively of medium-sized birds, the peregrine will occasionally hunt small mammals, small reptiles, or even insects. Reaching sexual maturity at one year, it mates for life and nests in a scrape, normally on cliff edges or, in recent times, on tall human-made structures. The peregrine falcon became an endangered species in many areas because of the widespread use of certain pesticides, especially DDT. Since the ban on DDT from the early 1970s, populations have recovered, supported by large-scale protection of nesting places and releases to the wild.
The peregrine falcon is a well respected falconry bird due to its strong hunting ability, high trainability, versatility, and – in recent years – availability via captive breeding. It is effective on most game bird species, from small to large.
Although photographers don't often say they like summer haze it can give some very dramatic conditions when the sun bursts through the clouds. These crepuscular rays at the weekend were really stunning over North Bovey and managed to capture this panorama.
You've probably noticed by now the red dress in all my latest photos from Iceland... A couple reasons for that: A. I had very little room in my travelling suitcase for extra outfits, especially considering I had to save suit-case space for transporting chocolate (yes, that was my most vital necessity for the trip), and B. When I was thinking ahead about creating an Icelandic self-portrait series, I wanted something that would depict "standing out". Not just a bright colour to stand out against the Icelandic backdrops, but more something of a reflection of my thoughts as of late.
Over the last couple years I have been blessed with several new people in my life, engaging with them and learning of their own thoughts and struggles and triumphs. I've been noticing friends who wish to blend in less and stand out more in this world, in a beautiful and positive way. And then friends who already stand out but want more than anything to blend in, to be normal. And It's got me thinking of my own journey, of my last couple years of my attempting to step out of my comfort zone: Not worrying so much about my ultra social-awkwardness, taking courage in letting myself be seen even in that awkwardness, and trying to live more whole-heartedly. I usually stay on the sidelines and try not to fully engage with other people's lives. I like to blend in and try not to be seen. I often picture myself getting a little cabin in the mountains far from civilization and being a hermit for the rest of my life with just the company of my pets (which, let's be honest... I still plan to do that someday). But even so, people still notice. People see me as I go about living my life. And I've spent too much time worrying what people think of me, my awkwardness and my quirks and my keeping to myself. But this has been something I'm learning to let go of, the fears of what people think. Whether I'm trying to blend in, or make myself known, I'm learning to accept myself as someone who doesn't need to worry, and learning not to be afraid to be different. Often all I want is to be silent, to imitate my surroundings, try to blend in, and curl up and forget everything but to exist only as a simple extension of humanity and nature.
But this year, to me, is about learning to take courage and not worry as I take each step on the path ahead of me . And If we're going to stand out, we might as well try our best to do so in a beautiful way.
Saturday's 17.32 BIF - CAR runs alongside the River Ehen behind 37401 and passes Sellafield's "up" outer home signal.
The buffer stop marks the end of the siding which at one time was the southern end of the Whitehaven, Cleator & Egremont Railway's 1869 divergence from the Furness Railway.
The line ran via Beckermet, Egremont, Woodend & Moor Row, rejoining the Furness at Mirehouse Junction south of Whitehaven Corkickle.
Wound down from the 1930s onward the last remaining section, between Beckermet Mines and here at Sellafield, closed in January 1970.
Vent stacks of the Sellafield complex can be seen above Watch Hill.
The rickety house track is quickly becoming obscured and forgotten along with the former Clinchfield depot as northbound CSX freight train Q692-27 thunders past the signals of the North End of the Dante, VA, siding on the afternoon of January 30, 2021.
It's been pretty rainy and drab in Devon today so here is a recent image of a vista looking towards Haytor in slightly nicer weather. I've never seen crepuscular rays coming from Haytor before and these were stunning. Another image I can add to my 'Haytor project'.

The first-generation of the Ford F-Series (also known as the Ford Bonus-Built trucks) is a series of trucks that was produced by Ford from the 1948 to the 1952 model years. The introduction of the F-Series marked the divergence of Ford car and truck design, developing a chassis intended specifically for truck use. Alongside pickup trucks, the model line included also panel vans, bare and cowled chassis, and marked the entry of Ford into the medium and heavy-duty truck segment.
Across North America, Ford assembled F-Series trucks at sixteen different facilities during its production. In Canada, Lincoln-Mercury sold the F-Series under the Mercury M-Series nameplate to expand coverage in rural areas. The first generation of the F-Series is the sole generation produced entirely with "Flathead" engines (inline-6 and V8).

The Galápagos tortoise or Galápagos giant tortoise (Chelonoidis nigra) is the largest living species of tortoise and 10th-heaviest living reptile, reaching weights of over 400 kg (880 lb) and lengths of over 1.8 meters (5.9 ft). With life spans in the wild of over 100 years, it is one of the longest-lived vertebrates. A captive individual lived at least 170 years.
The closest living relative (though not a direct ancestor) of the Galápagos giant tortoise is the Argentine tortoise (Chelonoidis chilensis), a much smaller species from South America. The divergence between C. chilensis and C. nigra probably occurred 6–12 million years ago, an evolutionary event preceding the volcanic formation of the oldest modern Galápagos Islands 5 million years ago. Mitochondrial DNA analysis indicates that the oldest existing islands (Española and San Cristóbal) were colonised first, and that these populations seeded the younger islands via dispersal in a "stepping stone" fashion via local currents. Restricted gene flow between isolated islands then resulted in the independent evolution of the populations into the divergent forms observed in the modern subspecies. The evolutionary relationships between the subspecies thus echo the volcanic history of the islands.
Despite a rebound, the species as a whole is classified as "vulnerable" by the International Union for Conservation of Nature (IUCN). Now Listed as Endangered.
MY FRIENDS, IN THIS DAYS I AM OFTEN THINKING ON HOW RELATED the events of our personal life and our world ARE ( wars, tragedies, earthquakes here and there, floods, hurricanes etc..)
IT MAKES MY FEEL VERY "SMALL ".
I WISH YOU A THOUGHTFUL WEEK!
The butterfly effect is a metaphor that encapsulates the concept of sensitive dependence on initial conditions in chaos theory; namely that small differences in the initial condition of a dynamical system may produce large variations in the long term behavior of the system.
The term "butterfly effect" itself is related to the work of Edward Lorenz, and is based in chaos theory and sensitive dependence on initial conditions, already described in the literature in a particular case of the three-body problem by Henri Poincaré in 1890[1]. He even later proposed that such phenomena could be common, say in meteorology. In 1898[2] Jacques Hadamard noted general divergence of trajectories in spaces of negative curvature, and Pierre Duhem discussed the possible general significance of this in 1908[3]. The idea that one butterfly could eventually have a far-reaching ripple effect on subsequent historic events. [WIKI]

37407 Blackpool Tower approaches Haddiscoe at the head of the "Off the Beaten Tracks" mini-tour part of the UK Railtours "Carols at Norwich Cathedral" special. This section of the tour was the Reedham to Lowestoft Yard leg of 1Z40 12.10 Norwich - Lowestoft (via Great Yarmouth), and 20142 Sir John Betjeman and 20189 were on the rear (standing in for 37423, which had failed the previous day with flat batteries).
The full tour ran as follows:
1Z39 07.22 King's Cross - Norwich via the East Coast Main Line, Peterborough (reverse) and the Ely West Curve;
1Z40 12.10 Norwich - Lowestoft via Acle, Great Yarmouth (reverse), Berney Arms, Reedham (reverse), Lowestoft Yard (reverse) and Oulton Broad North Jn. (reverse);
1Z42 15.26 Lowestoft - Norwich;
1Z43 16.10 Norwich - King's Cross via the Ely West Curve, Peterborough, Spalding, Sleaford, Grantham and the East Coast Main Line.
The train was operated by Rail Adventure, with 37407 supplied by Europhoenix, and the coaches by West Coast Railways (which had acquired the assets of Riviera Trains a few months earlier, hence the blue and grey mark 2 coaches). 37407 is, of course, no stranger to this line as it was one of the DRS-owned 37s hired to Greater Anglia to operate the "short set" a few years ago.
After photographing this on the "Acle Straight" on its way into Great Yarmouth in sun (see here) and then close to the Breydon Divergence on its way to Reedham (with only the leading locos in sun - so the shot is unlikely to be uploaded), I hurried back to the car to set off for here. Heavy slow-moving traffic on the A47 meant it took a while to pull away (especially as I was behind someone else), there was a queue at the Vauxhall roundabout, and then I just missed getting through a fairly new set of traffic lights on the A143 Beccles Road in Bradwell, which seemed to have five stages in the sequence so I was stopped for what seemed like an age (the vehicle in front of me went through several seconds after they had turned red). Thankfully, the traffic lights on the narrow bridge over the River Waveney at St. Olaves (immediately to the east of this bridge) stayed green as I approached. Unusually, I abandoned the car on the east side of the the long bridge over the waterway and railway (thinking it might save a few seconds), took my camera out of my bag and grabbed them both, and hurried up to where several photographers were standing, cameras pointing at the railway. 1Z40 had left Great Yarmouth two minutes late but was now four minutes early, and I could hear the 37 working hard...
With the camera already round my neck, I was able to adjust settings on my way up the bridge, and I reckon I had about five seconds to choose my spot and compose the shot before I began firing. After rushing across the road for a going-away shot (noting the trees which had cast a shadow over the track five years ago, when the "short set" finished, were no longer there), I then sat down for a moment on the crash barrier to catch my breath! When I later checked the images I took, I was a little disappointed to see the shadow across the rear of the train, but at least most of it was in sun - and I was grateful I'd managed to get a shot at all.

By touching each other at the creative core of their being, they release new energy which leads to more complex units. Greater complexity leads to greater interiority which, in turn, leads to more creative unions. Throughout the process, the individual elements do not lose their identity but rather deepen and fulfill it through union…. The more “other” they become in conjunction, the more they find themselves as “self.” At this point of history because of the shift from divergence to convergence, the forces of planetization are bringing about an unprecedented complexification of consciousness through the convergence of cultures and religions.

en.wikipedia.org/wiki/Iberian_chiffchaff
The Iberian chiffchaff (Phylloscopus ibericus) is a species of leaf warbler endemic to Portugal, Spain and North Africa, west of a line stretching roughly from the western Pyrenees via the mountains of central Spain to the Atlantic.
Taxonomy and etymology
The name "chiffchaff" is onomatopoeic, referring to the repetitive chiff-chaff song of the common chiffchaff (Phylloscopus collybita).[2] There are similar names in some other European languages, such as the Dutch Tjiftjaf, the German Zilpzalp and Welsh siff-saff.
The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific ibericus is Latin for "Iberian".[3]
Previously the Iberian chiffchaff was considered as a subspecies of the common chiffchaff. As of 2016, it is recognised as a separate species under the name Phylloscopus ibericus[4] for the following reasons (compared to the common chiffchaff):[5]
Brighter in colour
Greener rump
Yellower below
Vocalisations different
mtDNA sequence divergence
In past, erroneously listed as Phylloscopus brehmii.[6][7]
