Pythagorean triple

A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. Such a triple is commonly written (a, b, c), and a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k. A primitive Pythagorean triple is one in which a, b and c are coprime (that is, they have no common divisor larger than 1). For example, (3, 4, 5) is a primitive Pythagorean triple whereas (6, 8, 10) is not. A triangle whose sides form a Pythagorean triple is called a Pythagorean triangle, and is necessarily a right triangle.

32 + 42 = 52

The name is derived from the Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle. However, right triangles with non-integer sides do not form Pythagorean triples. For instance, the triangle with sides a=b=1 and c=2 is a right triangle, but (1,1,2) is not a Pythagorean triple because 2 is not an integer. Moreover, 1and 2 do not have an integer common multiple because 2 is irrational.

Pythagorean triples have been known since ancient times. The oldest known record comes from Plimpton 322, a Babylonian clay tablet from about 1800 BC, written in a sexagesimal number system. It was discovered by Edgar James Banks shortly after 1900, and sold to George Arthur Plimpton in 1922, for $10.

One example of a Pythagorean triple is a=3, b=4, and c=5: Ancient Egyptians used this group of Pythagorean triples to measure out right angles. They would tie knots in a piece of rope to create 3, 4, and 5 equal spaces. Three people would then hold each corner of the rope and form a right triangle!

right triangles during the construction process to help determine the slope of the pyramid. The Pythagorean Theorem states that given a right triangle with sides of length a and b respectively and a hypothenuse of length c, the lengths satisfy the equation a2 + b2 = c2.

Pyramids at Giza
All three of Giza’s famed pyramids and their elaborate burial complexes were built during a frenetic period of construction, from roughly 2550 to 2490 B.C.

When searching for integer solutions, the equation a2 + b2 = c2 is a Diophantine equation. Thus Pythagorean triples are among the oldest known solutions of a nonlinear Diophantine equation. The simplest linear Diophantine equation takes the form ax + by = c, where a, b and c are given integers. The solutions are described by the following theorem: This Diophantine equation has a solution (where x and y are integers) if and only if c is a multiple of the greatest common divisor of a and b.

Alan Alda | The 3 Rules of 3

We Were Built to Connect with Other People — Here’s How to Be Better At It. Before you follow another “tip” or “trick,” there’s something Alan Alda wants you to know.

His best tip to become a better communicator is what he calls the three rules of three. Listen to his practical hints for becoming a communication pro but, as he remarks, try to get there organically through the process. Alan Alda’s most recent book is If I Understood You, Would I Have This Look on My Face?

“So the first rule is, I try only to say three important things when I talk to people”.

“The second rule is, if I have a difficult thing to understand, if there’s something I think is not going to be that easy to get, I try to say it in three different ways”.

“And the third tip, which I always forget, is that if I have a difficult thing that’s hard to get, I try to say it three times through the talk”.

—- Alan Alda

Alan Alda

Alan Alda doesn’t want you to take “pro tips” from anyone-not even Alan Alda. When it comes to his area of expertise public speaking and empathetic communication there are no hacks or shortcuts; if you want to be a world class public speaker, you have to earn those stripes through the process of deeply understanding what it is to talk, listen, and connect.

Alda calls tips intellectual abstractions; it’s akin to the difference between information and knowledge, between parroting a few words in French and speaking the actual language. But, when pushed by yours truly at Big Think, Alda does give up the goods (willingly we promise no Alan Aldas were harmed in the making of this video).

Noise by Daniel Kahneman | 3 Distinctions

The Michael Shermer Show with Daniel Kahneman – Noise: A Flaw in Human Judgment

DESCRIPTION

Imagine that two doctors in the same city give
different diagnoses to identical patients. Now
imagine that the same doctor making a different
decision depending on whether it is morning or
afternoon, or Monday rather than Wednesday.
This is an example of noise: variability in
judgments that should be identical.

Shermer speaks with Nobel Prize winning
psychologist and economist Daniel Kahneman
about the detrimental effects of noise and what
we can do to reduce both noise and bias, and
make better decisions in: medicine, law, economic
forecasting, forensic science, bail, child
protection, strategy, performance reviews, and
personnel selection.

Three types of paradoxes

The Ways of Paradox and Other Essays

by W.V. Quine

There are essentially three categories of paradoxes

  • Falsidical – Logic based on a falsehood
  • Veridical – Truthful
  • Antinomy – A contradiction, real or apparent, between two principles or conclusions, both of which seem equally justified

Willard Van Orman Quine (AKA W. V. O. Quine, or “Van”to his friends) (1908 – 2000) was an American philosopher and mathematical logician, widely considered one of the most important philosophers of the second half of the 20th Century.

Cognitive Ease

Cognitive ease or fluency is the measure of how easy it is for our brains to process information. … The Cognitive ease principle reveals that when people have to switch to the second system of thinking, causing cognitive strain, they become more vigilant and suspicious.

Frequent repetition can be enough to convince people to believe things that are not true because familiarity generates a sense of cognitive ease. Called the mere-exposure effect, advertisers make use of it, but they aren’t the only ones. Information that is easy to understand also gives us a sense of cognitive ease.

Humans tend to avoid stressful and demanding cognitive strain, often making them vulnerable to many biases. This “laziness” and desire for cognitive ease often invites individuals to a world of irrationality where the decisions made can be detrimental.

The Symbolism and Spiritual Significance of the Number Three

The Spiritual Meaning of Numbers

Tetragrammaton by Francisco Goya: "The Name of God", YHWH in triangle, detail from fresco Adoration of the Name of God, 1772
Tetragrammaton by Francisco Goya: “The Name of God”, YHWH in triangle, detail from fresco Adoration of the Name of God, 1772

Three is the first number to which the meaning “all” was given. It is The Triad, being the number of the whole as it contains the beginning, a middle and an end. The power of three is universal and is the tripartide nature of the world as heaven, earth, and waters. It is human as body, soul and spirit.

In the first three numbers, all of the others are synthesized. From the union of oneness and duality (which is its reflection), that is, from triad, proceed all of the other numbers, and from this primordial triangle all figures derive.

There is also, for traditional civilizations, a direct relationship between numbers and letters of the alphabet, to the point where, with many alphabets, numbers were represented by letters, and had no special signs of their own. This is not the case with the early American cultures, which knew no alphabet, but we wish to call attention to this correspondence because not only the alphabetical code, but the numerical one, as well, describe all reality: that is, everything that is numerable or namable–in the sense of “ciphers,” harmonious measures, “proportions”–in sum, the totality of the cosmos, of the knowable.

This threeness or triad, has always been considered sacred–like oneness, duality, and all numbers–by virtue of its very properties and particular attributes. These properties and attributes are manifested in its threefold nature, which of itself is the inevitable expression of a principle, an archetypal fact, that solidifies in a series, as a representation of ideas and energies that materialize in magical, mysterious fashion while obeying precise, universal laws, which the numerical codes and their geometrical correspondences symbolize.

Trinity Symbol
Trinity Symbol

This symbol a triad or trinity. It is a symbol of the unity of body, mind and spirit. The symbol is of universal significance – it is found throughout history and all over the world. It was popularized early in this century by the Russian-born artist, philosopher and scientist Nicholas Roerich. (http://www.roerich.org). It can be interpreted in many different senses: spirit/mind/body in a circle of synthesis; past/present/future enclosed in the ring of eternity; art/science/religion bound in a circle of culture.

Chintamani
Chintamani

The oldest of Indian symbols, Chintamani, the sign of happiness, is composed of this symbol and it can be found in the Temple of Heaven in Beijing. It appears in the Three Treasures of Tibet; on the breast of the Christ in Memling’s famous painting; on the Madonna of Strasbourg; on the shields of the Crusaders and coat of arms of the Templars. It can be seen on the blades of the famous Caucasian swords called “Gurda” and on the swords of Japanese nobility.

It appears as a symbol in several philosophical systems. It can be discovered on the images of Gessar Khan and Rigden Djapo; on the “Tamga” of Timurlane and on the coat of arms of the Popes. It can be seen in the works of ancient Spanish painters and of Titian, and on the ancient ikon of St. Nicholas in Bari and that of St. Sergius and the Holy Trinity. It appears on the coat of arms of the city of Samarkand, on Ethiopian and Coptic antiquities, on the rocks of Mongolia, on Tibetan rings, on Buddhist banners, on the breast ornaments of all the Himalayan countries, and on the pottery of the Neolithic age.

big O Notation

Analysis of Algorithms

Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. It is a member of a family of notations invented by Paul Bachmann, Edmund Landau, and others, collectively called Bachmann–Landau notation or asymptotic notation.

Big Oh Running Time Complexity
Big Oh Running Time Complexity

Two simple concepts separate properties of an algorithm itself from properties of a particular computer, operating system, programming language, and compiler used for its implementation. The concepts, briefly outlined earlier, are as follows:

• The input data size, or the number n of individual data items in a single data instance to be processed when solving a given problem. Obviously, how to measure the data size depends on the problem: n means the number of items to sort (in sorting applications), number of nodes (vertices) or arcs (edges) in graph algorithms, number of picture elements (pixels) in image processing, length of a character string in text processing, and so on.

• The number of elementary operations taken by a particular algorithm, or its running time. We assume it is a function f(n) of the input data size n. The function depends on the elementary operations chosen to build the algorithm.

Algorithms are analyzed under the following assumption: if the running time of an algorithm as a function of n differs only by a constant factor from the running time for another algorithm, then the two algorithms have essentially the same time complexity. Functions that measure running time, T(n), have nonnegative values
because time is nonnegative, T(n) ≥ 0. The integer argument n (data size) is also nonnegative.

Definition 1 (Big Oh)

Big Oh Rank Meaning
Big Oh Rank Meaning

Let f(n) and g(n) be nonnegative-valued functions defined on nonnegative integers n. Then g(n)is O(f(n)) (read “g(n)is Big Oh of f(n)”) iff there exists a positive real constant c and a positive integer n0 such that g(n) ≤ c f(n) for all n > n0.

Note. We use the notation “iff ” as an abbreviation of “if and only if”.

Triple dog dare

Scene from A Christmas Story - I triple dog dare you

Verb. triple dog dare. (slang, US) Used to denote compounding levels of dare”seriousness”; the escalation of a double dog dare. I triple dog dare you to jump.

To “double dog dare” someone is to challenge them emphatically or defiantly, although the “challenge” is often meant humorously, or at least not very seriously: “I double dog dare you to eat the entire box of doughnuts!”

In the movie Inglorious Bastard’s, the spy, undercover as a German officer, orders another round of whiskey, telling the bartender, “Drei Gläser (three glasses) and holding three fingers up — his index, middle, and ring finger. … A true German would have ordered “three” with the index, middle finger, and thumb extended.

The French also start counting with their thumb for one. For two, they hold up the thumb and index finger. For three, they hold up the thumb, index finger and middle finger. In Costa Rica the three finger ‘OK” sign is used.

One of America’s oldest civil rights organizations has said it does not think the thumb and forefinger “OK” hand gesture is a white supremacist sign.

The Anti-Defamtion League (ADL) issued the clarification after two journalists known to be supporters of Donald Trump made the sign while standing behind the podium at the White House press briefing room.

The two reporters vehemently denied they were either white supremacists or that they were making a sign in support of such views. However, the image of them sparked a storm on social media, with some commentators arguing that the symbol was a way to indicate ‘white power’, as reported by The Independent.

3-click rule — the magic number – UX Collective

3-click rule — the magic number

A maximum of information in a minimum of words.

UI UX design
UI UX design

This is a particularly deep belief for your graphic designer friends for 10 years, but we have come a long way, and the usability tests have shown it for a while…

I will not lie to you any longer, users of your services will not leave your site or application if they can not find the information they are looking for in 3 clicks.

The number of clicks needed does not affect the success rate and even less the satisfaction of users: the important thing is to have a smooth, easy and understandable navigation (yes, the rules of 3 adjectives affect me too).

The scent of information

The concept is a simple idea and quite primitive as the name suggests : to have a good hunt, you must follow a good smell!

On a website or an application, the smell will take shape with the content, scented with confidence, the right word, the good image.

A little like my previous article about form field (Form fields — Required vs Optional), never forget that the most important thing when designing a product is to give the user the feeling of being in the center of all the expectations.

It’s a bit like setting a trap for a hungry bear, bait him, feed him to your final goal and he will follow you without even realizing it.

The key is your content: put it in value, coated to bring your user to be tempted to immerse himself in it and especially not let him lose The scent of information !

Once lost, the user hesitates, it becomes difficult for him to finish the action, and he will eventually notice the number of clicks you ask him to do.

Do not waste time worrying about the number of clicks, worry about the scent of information.

Disclamer :

I already see the crowd of designer dissatisfied ‘yes that’s fine theory, but when you can do 2 click instead of 6 is better no?’

YES, of course, this article is meant to make you think, to give you concrete information about the different studies done about the 3 clicks rule, but do not get me wrong, when you can do 2 clicks instead of 6 without spoiling the navigation experience, made it, but do not forget The scent of information.
