El Niño or La Niña

El Niño, the warm phase of ENSO (El Niño – Southern Oscillation weather pattern).

La Niña, the opposite of El Niño. The cold phase.

Oscillation, a repetitive back and forth at a regular interval.

We emerged from a very long run of El Niño which was followed closely by an ENSO-neutral (neither El Niño nor La Niña) period. Here in South Western Canada this means that last winter did not get that cold and it seemed to be a fairly short winter (in my memory anyway). The weather forecasters are now telling us that there is a very good chance that La Niña could bring a very cold winter.

El Niño and La Niña are normal weather patterns that fluctuate back and forth over the years and decades. They are much more predictable than the political adversaries they are blamed on and basically, what we need to do, is pay attention and dress for the occasion!

Adams, Kramer: The Redwoods, 1969

The book, The Redwoods (published in 1969 by Popular Library), by Kramer Adams, is cited by Gregory Jones in his Masters Theses, Coast redwood fire history and land use in the Santa Cruz Mountains, California (2014, San Jose State University).

It looks like a fairly rare book with only a handful of copies showing up in my online searches.

I have read a bit and will go through Gregory Jones’s Master’s Theses, Coast redwood fire history and land use in the Santa Cruz Mountains, tonight.

If you are unfamiliar with reading a theses, start with the introduction and then, what I do, is to move through the pages between the Introduction and the Discussion fairly quickly. I find that discussion sections can be quite interesting and, if you need more information on something that is being ‘discussed’ – you can go back and the information is probably in those pages that you turned through quickly.

If I find more by Gregory Jones, I will add it here. If you have any comments or would like to discuss this paper, I would like to hear from you!

Here are the links you need to find this work:

I love this book and, I want to share some of what is in it, with links, so that the information can be used by artists and people doing various crafts.  The old information is fascinating and, coupled with what is available today – it is usable!  Be safe!  Be careful!  Most of this is not safe for children.  Please, always  keep safety in mind.

IMG_0088As I get going on this little project, I will add excerpts and links below.  Please feel free to comment, add and send links – the more information and the easier it becomes to find it, the better for everyone!

I am going to try to update this post regulary, with more excerpts and more links, as I work my way through this book!

Chapter I:  Introductory. Colour, Colours, Paints and Varnishes.

from page 4, “Cause of Colour in Coloured Bodies. — The actual reasons why bodies such as vermilion, magenta, or emerald green are coloured, it is almost impossible to investigate in the present state of knowledge, since the cause, whatever it may be, must be due to the molecular construction of the different compounds about which very little is known…”

  • Geology is the key word here.  Geologists have been working to increase our knowledge base of Earth in general and specifically, in this case, our knowledge of pigments. Here is a great place to read about colour, Dust to Dust:  A Geology of Color by Heidi Gustafson  –  if you like playing in the dirt, foraging for rocks and then doing something with them, Heidi Gustafson’s website has some great information in it!

from page 5, “Colour Theories. — Two theories of colour are in use to explain the coloured effects of light.  The old theory… Brewster… The more modern theory, first broached by Young and more fully developed by Helmholtz…”

  • Sir David Brewster’s (1871-1868) work on colour theory is from the 1830’s.  His work “On a new analysis of solar light” was written in 1831 and published by Charles Tait, and Bell & Bradfute; and T. Cadell, London.  One place I have found credit for Sir David Brewster’s theories on the perception of colour is in an article by Peter John Brownlee, “Color Theory and the Perception of Art“, published in 2009 by The University of Chicago Press Journals.
  • Thomas Young, M.D. (1773-1829), was a scientist studying human perception of colour and in 1802 wrote a treatise speculating on how the human eye works to perceive colour.  There is also a lecture series by Thomas Young, “A Course of Lectures on Natural Philosophy and the Mechanical Arts” which was published in London by Joseph Johson, St. Paul’s Church Yard, in 1807.
  • Hermann von Helmholtz (1821-1894), continued work on the development of Thomas Young’s theories of human colour perception.  This work is known as the “Young-Hemholtz Theory” and furthers Thomas Young’s theories as to how our eyes actually work to perceive color.
  • This body of knowledge has been expanded upon for more than the 250 years shown in these writings and continues to grow today.  Here are just a few examples of the psychology of colour perception that are a little more recent.

from page 6, “Colours. — … the term “colours” is used in two senses — first, to express the sensation which light of various kinds… excites on the retina of the eye, and which sensation is purely functional; second, … [the] imparting [of] colour to other bodies;  such bodies are known as colouring matters and may be divided into two groups, dyestuffs and pigments….”

  • sensations of light, through rather than on the retina, continue to be studied by the scientific and psychological communities today.  This is fascinating research and the McGovern Medical School at the University of Texas has some open access resources on this subject.
  • dyestuffs, as referred to by George Hurst, are materials which provide ‘soluable’ material that can be used to add colour to another item.  In other words, dyeing or staining, imparts temporary colour to other items.  If you have access to a copy of the Oxford English Dictionary, the definition and history of the word ‘dyestuff’ is fascinating.  Most libraries have a copy of the OED and may also allow access to the online version.
  • pigments, then, as defined by George Hurst in 1892, are ‘nonsoluable’ materials which provide a more permanent, opaque colour to things like paint.  Most of the chapters in this book are about pigments, where to find them, what to find them in, how to extract them and, how to use them.

… of things relative

There are dozens of tiny green tomatoes on this plant.  Even more exciting, there are dozens more bright yellow flowers….

 

Currently Reading:  The A B C of Atoms, by Bertrand Russell.  E.P. Dutton & Company, New York, 1923.  Date of first issue, 1908.

“But even if the size of an electron should ultimately prove… to be related to the size of the universe, that would leave a number of unexplained brute facts, notably the quantum itself, which has so far defied all attempts to make it seem anything but accidental.  It is possible that the desire for rational explanation may be carried too far.  This is suggested by some remarks… by Eddington, in his book, Space, Time and Gravitation…  The theory of relativity has shown that most of the traditional dynamics, which was supposed to contain scientific laws, really consisted of conventions as to measurement, and was strictly analogous to the “great law” that there are always three feet to a yard.  In particular, this applies to the conservation of energy.  This makes it plausible to suppose that every apparent law of nature which strikes us as reasonable is not really a law of nature, but a concealed convention, plastered on to nature by our love of what we, in our arrogance, choose to consider rational.  Eddington hints that a real law of nature is likely to stand out by the fact that it appears to us irrational, since in that case it is less likely that we have invented it to satisfy our intellectual taste.  And from this point of view he inclines to the belief that the quantum-principle is the first real law of nature that has been discovered in physics.

This raises a somewhat important question:  Is the world “rational,” i.e., such as to conform to our intellectual habits?  Or is it “irrational,” i.e., not such as we should have made it if we had been in the position of the Creator?  I do not propose to suggest an answer to this question.”

I LOVE skipping to the end of a book!

 

 

In The Beginning (of this blog)…

There was a tomato plant….

Several years later, there is another tomato plant!  It is gaining momentum!

2017-06-07_08.19.341

No need for a chain of command to appear here or, is there?

Sir!  Do we have enough tomatoes yet?  Do we need a discussion on this matter?  What about the aphids?  Sir!  Sir?  There are aphids!

Aphids?  This is not the Middle Ages!  We have to ask for permission.  This isn’t something we can just ‘handle.’  We need a committee!

Sir?

Stick around kid, I’m calling parliament — I’m on hold….  Be with you in a minute!  Do we have a call-back number?

SIR?

Offensive and Defensive Weapons – Churchill’s Thoughts…

I was reading.  It happens….

Actually, I was reading Winston Churchill’s “The Coming Storm.”  My thought on reading the following was that it stands repeating.

 

“The Foreign Secretary told us that it was difficult to divide weapons into offensive and defensive categories.  It certainly is, because almost every conceivable weapon may be used in defence or offence; either by an aggressor or by the innocent victim of his assault.  To make it more difficult for the invader, heavy guns, tanks, and poison gas are to be relegated to the evil category of offensive weapons.  The invasion of France by Germany in 1914 reached its climax without the employment of any of these weapons.  The heavy gun is to be described as “an offensive weapon.”  It is all right in a fortress; there it is virtuous and pacific in its character; but bring it out into the field – and, of course, if it were needed, it would be brought out into the field – and it immediately becomes naughty, peccant, militaristic, and has to be placed under the ban of civilisation.  Take the tank.  The Germans, having invade France, entrenched themselves; and in a couple of years they shot down 1,500,000 French and British soldiers who were trying to free the soil of France.  The tank was invented to overcome the fire of the machine-guns with which the Germans were maintaining themselves in France, and it saved a lot of lives in clearing the soil of the invader.  Now, apparently, the machine-gun, which was the German weapon for holding on to thirteen provinces of France, is to be the virtuous, defensive machine-gun, and the tank, which was the means by which these Allied lives were saved, is to be placed under the censure and obloquy of all just and righteous men…

A truer classification might be drawn in banning weapons which tend to be indiscriminate in their action and whose use entails death and wounds, not merely on the combatants in the fighting zones, but on the civil population, men, women, and children, far removed from those areas.  There, indeed, it seems to me would be a direction in which the united nations assembled at Geneva might advance with hope…”

Winston Churchill.  The Gathering Storm.  1948.  Houghton Mifflin Company.

 

Weapons do not harm people. People harm people.  People with weapons can usually cause more harm than people without weapons.  I believe that a good portion of Britain’s Bobbys are still armed only with a hickory nightstick…
