This document presents work done as part of a "Maths and Reality" project studying geometric transformations and fractals. It summarizes the aims of the project, which are to study geometric transformations, represent reality through mathematical models using transformations, integrate traditional teaching with new technologies, build known fractals, and make graphic representations of fractals. It then provides details on specific fractals and methods analyzed as part of this work, including definitions of fractals, origins of fractal geometry, complex numbers, Newton's equations, and specific fractal examples generated through Maple code.
This presentation continues with my series of videos on Straight Lines, coordinate geometry.
Here, we learn how to calculate distance of a point from a line and also distance between 2 parallel lines.
This is useful for grade 11 math students. Problems are explained in a simple and easy way.

Thue showed that there exist arbitrarily long square-free strings over an alphabet of three symbols (not true for two symbols). An open problem was posed, which is a generalization of Thue’s original result: given an alphabet list L = L1, . . . , Ln, where |Li| = 3, is it always possible to find a square-free string, w = w1w2 . . . wn, where wi ∈ Li? In this paper we show that squares can be forced on square-free strings over alphabet lists iff a suffix of the square-free string conforms to a pattern which we term as an offending suffix. We also prove properties of offending suffixes. However, the problem remains tantalizingly open.
This talk is going to be centered on two papers that are going to appear in the following months:

Earlier a place value notation number system had evolved over a leng.pdfbrijmote
Earlier a place value notation number system had evolved over a lengthy period with a number
base of 60. It allowed arbitrarily large numbers and fractions to be represented and so proved to
be the foundation of more high powered mathematical development.
Number problems such as that of the Pythagorean triples (a,b,c) with a2+b2 = c2 were studied
from at least 1700 BC. Systems of linear equations were studied in the context of solving number
problems. Quadratic equations were also studied and these examples led to a type of numerical
algebra.
Geometric problems relating to similar figures, area and volume were also studied and values
obtained for π.
The Babylonian basis of mathematics was inherited by the Greeks and independent development
by the Greeks began from around 450 BC. Zeno of Elea\'s paradoxes led to the atomic theory of
Democritus. A more precise formulation of concepts led to the realisation that the rational
numbers did not suffice to measure all lengths. A geometric formulation of irrational numbers
arose. Studies of area led to a form of integration.
The theory of conic sections shows a high point in pure mathematical study by Apollonius.
Further mathematical discoveries were driven by the astronomy, for example the study of
trigonometry.
The major Greek progress in mathematics was from 300 BC to 200 AD. After this time progress
continued in Islamic countries. Mathematics flourished in particular in Iran, Syria and India. This
work did not match the progress made by the Greeks but in addition to the Islamic progress, it
did preserve Greek mathematics. From about the 11th Century Adelard of Bath, then later
Fibonacci, brought this Islamic mathematics and its knowledge of Greek mathematics back into
Europe.
Major progress in mathematics in Europe began again at the beginning of the 16th Century with
Pacioli, then Cardan, Tartaglia and Ferrari with the algebraic solution of cubic and quartic
equations. Copernicus and Galileo revolutionised the applications of mathematics to the study of
the universe.
The progress in algebra had a major psychological effect and enthusiasm for mathematical
research, in particular research in algebra, spread from Italy to Stevin in Belgium and Viète in
France.
The 17th Century saw Napier, Briggs and others greatly extend the power of mathematics as a
calculatory science with his discovery of logarithms. Cavalieri made progress towards the
calculus with his infinitesimal methods and Descartes added the power of algebraic methods to
geometry.
Progress towards the calculus continued with Fermat, who, together with Pascal, began the
mathematical study of probability. However the calculus was to be the topic of most significance
to evolve in the 17th Century.
Newton, building on the work of many earlier mathematicians such as his teacher Barrow,
developed the calculus into a tool to push forward the study of nature. His work contained a
wealth of new discoveries showing the interaction between mathemat.
Associate Professor Anita Wasilewska gave a lecture on "Descriptive Granularity" in the Distinguished Lecturer Series - Leon The Mathematician.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

5. The work I’m introducing comes
from the study and the commitment
I have done in the project of
“Maths and Reality”. It is a national
project linked to Perugia
University. It is an extra activity
work that has been made in our
school for seven years by teacher
Anna Alfieri.
I also presented this work
at the National
Convention “Maths
Experiences in
Comparison” held in
Perugia University from
May 3rd
to May 5th
2011.
6. Aims of the project:
• To Study the geometrical
transformations;
• To Learn to represent the
reality through mathematical
models by using geometrical
transformations;
• To Integrate the traditional
didactics with new
technologies (use of maple);
• To Build known fractals
(Sierpinski gasket, snowflake
of koch…) identifying the
geometrical transformations
which describe them
• To Make graphic
representations through
Maple
• To Conjecture and make
individual simulations.
7. Contents:
Fractals in general;
Definition of a fractal;
Origins of fractal geometry;
Complex numbers;
Newton’s equations;
My fractals;
8. Since the end of the XIX century Science has
focused on a different study of complex systems.
These interests started off the study of the
“deterministic chaos”, based on the situations of
chaos obtained through mathematical and physical
deterministical process.
In the real universe there are infinite “perturbing” elements
This complexity can be simplified by
Complex and chaotic geometric figures determined for
approximation from a recoursive
Function.
9. Koch Lace
A geometric figure where the same
shape is repeated on a smaller
uninterruptedly scale.
10. A fractal must have some important characteristics:
Autosimilarity:
If the details are observed on different
scales, we can see an approximative
similarity to such an Original fractal.
Indefinite Resolution: It Is not possible to define the
border of the figure
11. Made his first studies on fractals
identifying the topological properties,
without nevertheless
giving them a graphic representation
because he didn’t have capability of
calculation.
12. The founder of fractal geometry was:
a comtemporary mathematician that, in the first years of
80‘s, published the results of his research in the
volume “the fractal geometry of nature” founding the
fractal geometry. The name fractal derives from the
latin fractus , because its dimention is not integer.
13. Was born in 1924 in Warsaw,
he studied at the Ecole
Polytechnique and at Paris
university, where he
graduated in the 50’s in
mathematics. Then he
became professor of applied
mathematics at Harvard
University, and professor of
mathematics science at Yale
University. He received
several prizes, like the Wolf
Prize for phisics. Since the
60’s he has devoted himself to
the studies of finance.
14. Objectives:
xⁿ±a=0
Knowledge of complex numbers;
Application of complex numbers;
Study of iterative fractals by
Newton’s equation.
19. VECTORS AND COMPLEX
NUMBERS:
Let’s consider a complex number a+ib and
let’s interpret the coefficients of the real and
the imaginary part like the components of a
vector named OP.
a+ib
y
O x
Pib
a
20. THE TRIGONOMETRIC FORM OF A
COMPLEX NUMBER:
α
O
y
P
x
b
a
a+ib=r(cosα+ i sinα)
A complex number a+ib is the equivalent of the
vector OP that has its components a and b and its
coordinates in P(r;α), so we can write:
a=r·cosα; b=r·sinα.
21. THE n-th ROOTS OF A COMPLEX NUMBER:
ⁿ√z=v
Generally we can calculate the n-th roots
of a complex number by the equation:
ⁿ√r(cosα+i sinα)=ⁿ√r cos α+2π + isin α+2π
n n
Given two complex
numbers z and v, we
can say that v is the
n-th root of z if vⁿ=z.
22. Now we can calculate the n-th roots of the
equation z^3-8=0:
k=0 2 cosπ+isinπ =2i
2 2
k=1 2 cos7π+isin7π =√3-i
6 6
k=2 2 cos 11π+i sin11π = √3-i
6 6
24. Let’s follow an example:
Suppose we have a curve that has an equation
like y=xn
+a.
25. To find the point of intersection with the axis of abscissa we
can make a system between the last one and the tangent
line to the curve that passes through the point x0:
y-y0=m(x-x0)
y=0
The tangent line of the
curve that passes
through x0
(where
y0=f(x0) e m=f’(x0))The equation of the
axis of abscissa
36. <<Fractals help to find a new
representation starting from the
point that the “small” in nature
is nothing but the copy of the
“big”. I’m firmly convinced that,
in a very short time, Fractals will
be employed in the
comprehension of the neural
processes and the human mind
will be their new frontier.>>
