  Rudolf Steiner - Wikipedia, the free encyclopedia
Steiner argued that increased autonomy for the three spheres would not eliminate their mutual influence, but would cause that influence to be exerted in a more healthy and legitimate manner, because the increased separation would prevent any one of the three spheres from dominating.
Steiner periodically affirmed that gaining access to the unusual forms of consciousness supposedly embodied in some of his works was not a matter of believing in or having faith in whatever he chose to say about spiritual beings.
Steiner also occasionally averred that this consciousness of the spirit was not so much related to the content of his statements, where he tells readers the characteristics of this or that spiritual being (or something similar) that he says he has perceived.

Steiner also argues that Clause D in the contract should be declared void as a matter of law, and thus cannot be applied so as to limit any liability that might be based on the above three theories.
Steiner's complaint speaks in terms of a failure to perform rather than a negligent undertaking, using language alleging ADT's liability for a "failure to inspect, repair and maintain" the system.
Steiner urges this Court to declare Clause D to be invalid as against public policy.

In mathematics, a Steiner system is a type of block design.
A Steiner S(l,m,n) system is an n-element set S together with a set of m-element subsets of S (which we will call the special m-element subsets) with the property that each l-element subset of S is contained in exactly one of the special m-element subsets.
If S is a Steiner triple system, we can define a multiplication on it by setting aa = a for all a in S, and ab = c if {a,b,c} is a triple.

 An Introduction to Steiner Education - by Francis Edmunds
Rudolf Steiner's educational system, well established and respected on the European continent, is gradually spreading internationally.
The role of the class teacher, the 'main lesson', temperaments, attitudes to discipline, competition and examinations are all discussed, and answers given based on the author's many years of rich and varied experience as an educator of both children and adults.
This volume is an excellent introduction to the theory and practice of Steiner education, both for teachers or educationalists who would like to know more about Steiner's ideas, and for parents thinking of sending their child to a Waldorf school.

 Antroposophy :: How they learn at a different school of thought
Edinburgh’s own Steiner school in Merchiston, like all the 750 Steiner schools worldwide, is run along the lines devised by Austrian academic Rudolf Steiner, who died 80 years ago this year.
It was once derided as a dangerous cult, but now the main criticism of the Steiner system is that it’s fine if pupils want to be a fashion designer but not if they want to be a brain surgeon.
And some Steiner schools in Scotland - though not the Edinburgh one - have been criticised by HM inspectors for not placing enough emphasis on basic reading and writing as well as giving pupils coursework and homework that is "insufficiently challenging".

 The Watchman Expositor: Waldorf Charter School Controversy
Rudolf Steiner was born in 1861 in Austria, and even at an early age he was inclined towards the mystical, the psychic and the occult, including contact with the dead (necromancy).
Consistent with his Anthroposophical system, Steiner designed an educational method which its advocates claim is "responsive to the developmental phases in childhood and [the] nurturing of children's imaginations" ("Frequently Asked Questions About Waldorf Education").
According to Steiner, Anthroposophy is an essential foundation of the Waldorf educational philosophy, in which the teacher fosters a particular teacher-student relationship considered essential to the learning process.

 Introduction and ToC: Linearly derived Steiner triple systems   (Site not responding. Last check: 2007-10-08)
To find a ``linear extension'' of a Steiner triple system one restricts one's attention to those 4-subsets of the underlying set of the system that are symmetric differences of two triples --- that is, those 4-subsets that are the support of the binary sum of the incidence vectors of two triples.
There are Steiner triple systems whose graphs have chromatic number two; they are linearly derived and seem to form an interesting class of systems, which, as far as we know, have never been considered.
Since the maximum possible degree of the graph of a Steiner triply system is eight, it follows from Brooks's theorem that the chromatic number of the graph is at most eight.

He or she will receive support for trying to conform to Steiner, not for critiquing him objectively, which implies the possiblity of judging the idea to be wrong.
The diversity of families at a Waldorf school results from the appeal of the system to the parents, and the system's presenting itself as acceptable by all faiths, not from the parents' knowledge of the Anthroposophical world-view.
Steiner's seems to have been an intelligent admirer of Darwin and his now-orthodox theory of physical/biological evolution (though of course he included much that is "spiritual" and speculative under the "evolution" rubric), but that does not excuse Wilkinson's emphasis on dogmatic conformity.

Steiner cited a study he completed with Kiki Chang, M.D., and Terence Ketter, M.D., that look at psychopathology among 60 children ranging in age from 6 to 18 years old who had at least one biological parent with bipolar I or II disorder (Chang et al., 2000).
In their own research, Steiner and colleagues sought to evaluate the effectiveness of the divalproex in preventing angry and aggressive outbursts and other uncontrollable emotions among 61 violent, conduct disordered youths, aged 14 to 18.

In general we will say that the $ \lambda_1$-fold kite system $(X,K)$ is nested in the $\lambda_2$-fold block design $(X,B)$ provided a kite can be selected from each of B so that the resulting collection of kites is K. We have the same definition for the nesting of a $\lambda_1$-fold $4$-cycle system $(X,C)$.
Each parameter of the system corresponds to a row of the array and each test to be performed on the system correspond to a column; the covering array property requires that every possible pair of values for any pair of parameters is covered by some test.
These graphs, which we call extended Petersen graphs, arise naturally in the context of a construction of Steiner systems S(2,4,v) with maximal arcs but seem to be interesting on their own.

 ^  Dugan, Dan: Why Waldorf Programs are Unsuitable for Public Funding
Steiner was appointed head of the German section of Theosophy by Annie Besant in 1902.
Steiner was something of a fundamentalist Platonist, saying that the real world was all illusion, that objects are reflections of eternal essences in the spiritual world; but for Steiner the essences weren?t abstractions, they were living beings.
Steiner claimed to make "exact scientific observations" in the spiritual world, so nothing that he said could be discussed substantially by his followers without questioning the foundations of the faith.

Thus the systems of full 2-rank are seen as the building blocks since, from the binary point of view, Steiner triple systems of full 2-rank must be viewed as unintelligible and hence taken as given facts of life.
The mandarins in the binary world peopled by Steiner triple systems are the systems given by the points and lines of a projective geometry over the binary field.
But, the smaller the 2-rank the closer the system is to the classical system of points and lines of a projective geometry over the two-element field and it makes sense to say something about such systems.

Unfortunately many software systems are "fragile" in the sense that they are unreliable, suffer from security and performance lapses, and are difficult to maintain and upgrade to satisfy new demands.
