Qigong. Qigong, qi gong, chi kung, or chi gung (simplified Chinese: 气功; traditional Chinese: 氣功; pinyin: qìgōng; Wade–Giles: chi gong; literally: "Life Energy Cultivation") is a holistic system of coordinated body posture and movement, breathing, and meditation used for health, spirituality, and martial arts training. With roots in Chinese medicine, philosophy, and martial arts, qigong is traditionally viewed as a practice to cultivate and balance qi (chi) or what has been translated as "life energy".[1] According to Daoist, Buddhist, and Confucian philosophy, respectively, qigong allows access to higher realms of awareness, awakens one's "true nature", and helps develop human potential.[2] Qigong practice typically involves moving meditation, coordinating slow flowing movement, deep rhythmic breathing, and calm meditative state of mind.

Over the centuries, a diverse spectrum of qigong forms developed in different segments of Chinese society. Etymology[edit] Main articles: Qi and Gongfu. Mnemonic. Knuckle mnemonic for the number of days in each month of the Gregorian Calendar. Each protruding knuckle represents a 31-day month. A mnemonic (RpE: /nəˈmɒnɨk/,[1] AmE: /nɛˈmɑːnɪk/ the first "m" is silent), or mnemonic device, is any learning technique that aids information retention. Mnemonics aim to translate information into a form that the brain can retain better than its original form.

Even the process of merely learning this conversion might already aid in the transfer of information to long-term memory. The word mnemonic is derived from the Ancient Greek word μνημονικός (mnēmonikos), meaning "of memory, or relating to memory"[2] and is related to Mnemosyne ("remembrance"), the name of the goddess of memory in Greek mythology.

Ancient Greeks and Romans distinguished between two types of memory: the 'natural' memory and the 'artificial' memory. "Memory Needs Every Method Of Nurturing Its Capacity" is a mnemonic for how to spell mnemonic. History[edit] Applications[edit] See also[edit] Военная мысль ]-- Суворов А.В. Наука побеждать.

Statement of Intent I am going to put down here a partial instruction on how to use both happiness and suffering as the path to enlightenment. There are two parts: 1) how to use suffering as the path, 2) and how to use happiness as the path. Each one is approached firstly through relative truth, and then through absolute truth. 1) How to Use Suffering as the Path to Enlightenment i. This is because the nature of any perception or idea, be it happiness or sorrow, is to grow stronger and stronger the more we become accustomed to it.

The approximation of the square root of 2 is four sexagesimal figures, which is about six decimal figures. 1 + 24/60 + 51/602 + 10/603 = 1.41421296...[1] Numerical analysis is the study of algorithms that use numerical approximation (as opposed to general symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics).

One of the earliest mathematical writings is a Babylonian tablet from the Yale Babylonian Collection (YBC 7289), which gives a sexagesimal numerical approximation of , the length of the diagonal in a unit square. Being able to compute the sides of a triangle (and hence, being able to compute square roots) is extremely important, for instance, in astronomy, carpentry and construction.[2] Numerical analysis continues this long tradition of practical mathematical calculations. Much like the Babylonian approximation of General introduction[edit] History[edit] and. Fast Fourier transform. Frequency and time domain for the same signal A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. A Fourier transform converts time (or space) to frequency and vice versa; an FFT rapidly computes such transformations by factorizing the DFT matrix into a product of sparse (mostly zero) factors.[1] As a result, fast Fourier transforms are widely used for many applications in engineering, science, and mathematics.

The basic ideas were popularized in 1965, but some FFTs had been previously known as early as 1805. Fast Fourier transforms have been described as "the most important numerical algorithm[s] of our lifetime".[2] Overview[edit] The best-known FFT algorithms depend upon the factorization of N, but there are FFTs with O(N log N) complexity for all N, even for prime N. Is an N-th primitive root of unity, and thus can be applied to analogous transforms over any finite field, such as number-theoretic transforms. Algorithms[edit] The Electric Shock Questions. Effects and Symptoms Evan Mayerhoff High Voltage Connection, Inc. Questions that cross everyone’s mind who has worked on electronics are: what does it take to feel a shock, and at what level can you get into serious trouble. The simple answer is that low levels of electricity have the possibility to cause injury, either directly or indirectly.

There is some data that indicates that under certain extreme conditions the maximum reasonable safe voltage is only 10V ac. Included in this article are physiological effects of varying magnitude of current, and a listing of symptoms. (In researching this article, I was surprised to learn that some important data was obtained by experimenting on human subjects, about 35 years ago.) While previous articles in these newsletters have dealt with defining high voltage, a glossary of related terms, and spacing considerations, it is safety that we think about all the time.

Books. Thirty-Six Stratagems. The Art of War by Sun Tzu. Commentary: Many comments have been posted about The Art of War. Download: A 60k text-only version is available for download. The Art of WarBy Sun Tzu Translated by Lionel Giles I. Laying Plans 1. Sun Tzu said: The art of war is of vital importance to the State. 2. It is a matter of life and death, a road either to safety or to ruin.

Hence it is a subject of inquiry which can on no account be neglected. 3. The art of war, then, is governed by five constant factors, to be taken into account in one's deliberations, when seeking to determine the conditions obtaining in the field. 4. Nodewerk. Principles of War. The earliest known Principles of War were documented by Sun Tzu, circa 500 BCE. Machiavelli published his "General Rules" in 1521. Henry, Duke of Rohan established his "Guides" for war in 1644. Marquis de Silva presented his "Principles" for war in 1778. Henry Lloyd proffered his version of "Rules" for war in 1781 as well as his "Axioms" for war in 1781.Then in 1805, Antoine-Henry Jomini published his "Maxims" for War version 1, "Didactic Resume" and "Maxims" for War version 2.

Clausewitz wrote his version in 1812 building on the work of earlier writers. There are no agreed Principles of War, not even in the NATO alliance although many of its members have their own. Napoléon Bonaparte[edit] Additionally, since their first appearance in English of the military maxims of Napoleon in 1831, all English translations have relied upon the extremely incomplete French edition of General Burnod published in 1827.
