Universe
There are many competing theories about the ultimate fate of the universe. Physicists remain unsure about what, if anything, preceded the Big Bang. Many refuse to speculate, doubting that any information from any such prior state could ever be accessible. There are various multiverse hypotheses, in which some physicists have suggested that the Universe might be one among many or even an infinite number of universes that likewise exist.[11][12] Historical observation XDF size compared to the size of the Moon – several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view – each light speck is a galaxy – some of these are as old as 13.2 billion years[13] – the visible Universe is estimated to contain 200 billion galaxies. XDF image shows fully mature galaxies in the foreground plane – nearly mature galaxies from 5 to 9 billion years ago – protogalaxies, blazing with young stars, beyond 9 billion years.

Cosmos Cosmos is the Universe regarded as an ordered system.[1] The philosopher Pythagoras is regarded as the first person to apply the term cosmos (Greek κόσμος) to the order of the Universe.[2] Cosmology[edit] Cosmology is the study of the cosmos in several of the above meanings, depending on context. All cosmologies have in common an attempt to understand the implicit order within the whole of being. In this way, most religions and philosophical systems have a cosmology. In physical cosmology, the term cosmos is often used in a technical way, referring to a particular spacetime continuum within the (postulated) multiverse. Theology[edit] In theology, the term can be used to denote the created Universe, not including the creator. See also[edit] References[edit] External links[edit]

Light-year The light-year is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist and popular science publications. The unit usually used in professional astrometry is the parsec (symbol: pc, approximately 3.26 light-years; the distance at which one astronomical unit subtends an angle of one second of arc).[1] Definitions[edit] As defined by the IAU, the light-year is the product of the Julian year[note 2] (365.25 days as opposed to the 365.2425-day Gregorian year) and the speed of light (299792458 m/s).[note 3] Both these values are included in the IAU (1976) System of Astronomical Constants, used since 1984.[3] From this the following conversions can be derived. Other high-precision values are not derived from a coherent IAU system. History[edit] The first successful measurement of the distance to a star other than our Sun was made by Friedrich Bessel in 1838. Distances in light-years[edit] Related units[edit] See also[edit]

Samurai Samurai around the 1860s Samurai (侍?), usually referred to in Japanese as bushi (武士?, [bu͍ꜜ.ɕi̥]) or buke (武家?), were the military nobility of medieval and early-modern Japan. By the end of the 12th century, samurai became almost entirely synonymous with bushi, and the word was closely associated with the middle and upper echelons of the warrior class. History Asuka and Nara periods Following the Battle of Hakusukinoe against Tang China and Silla in 663 AD that led to a Japanese retreat from Korean affairs, Japan underwent widespread reform. The Taihō Code classified most of the Imperial bureaucrats into 12 ranks, each divided into two sub-ranks, 1st rank being the highest adviser to the Emperor. Heian period In the early Heian period, the late 8th and early 9th centuries, Emperor Kammu sought to consolidate and expand his rule in northern Honshū, but the armies he sent to conquer the rebellious Emishi people lacked motivation and discipline, and failed in their task.

Sons et lumières Like many, you enjoy the fireworks ... but have you ever admired the colors in mind, and only the colors ???? They amaze and dazzle, with hidden effects, from “color symbols”. And if these fireworks unite so many people at nightfall, is that the colors they emit left us all stunned… small or large. We are amazed by the magic of chemistry, first. Manufacturing processes which are obviously far from thinking of when you push “oh !” This shows us once again that the colors are related to the welfare, a way : those that relax, those that encourage and / or facilitate reflection. Indeed, each of them produces a condition for both our mental state and physical fitness. There are different color schemes that can act on your emotions like on your body so favorable, that is able to provide you with form, serenity and tranquility. The relaxing colors are blue and its variations chromatic, who prefer the peace and contemplation in a bedroom, to relieve stress and tensions during the day. Principle ?

Quantum mechanics Description of physical properties at the atomic and subatomic scale Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.[2]: 1.1 It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale.[3] Overview and fundamental concepts Quantum mechanics allows the calculation of properties and behaviour of physical systems. A fundamental feature of the theory is that it usually cannot predict with certainty what will happen, but only give probabilities. . and , where Here

Ninja A ninja (忍者?) or shinobi (忍び?) was a covert agent or mercenary in feudal Japan. The functions of the ninja included espionage, sabotage, infiltration, and assassination, and open combat in certain situations.[1] Their covert methods of waging war contrasted the ninja with the samurai, who observed strict rules about honor and combat.[2] The shinobi proper, a specially trained group of spies and mercenaries, appeared in the Sengoku or "warring states" period, in the 15th century,[3] but antecedents may have existed in the 14th century,[4] and possibly even in the 12th century (Heian or early Kamakura era).[5][6] In the unrest of the Sengoku period (15th–17th centuries), mercenaries and spies for hire became active in the Iga Province and the adjacent area around the village of Kōga, and it is from their ninja clans that much of our knowledge of the ninja is drawn.

Colour Music Cosmic microwave background The cosmic microwave background (CMB) is the thermal radiation assumed to be left over from the "Big Bang" of cosmology. In older literature, the CMB is also variously known as cosmic microwave background radiation (CMBR) or "relic radiation." The CMB is a cosmic background radiation that is fundamental to observational cosmology because it is the oldest light in the universe, dating to the epoch of recombination. With a traditional optical telescope, the space between stars and galaxies (the background) is completely dark. However, a sufficiently sensitive radio telescope shows a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object. The CMB is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380,000 years old. Features[edit] History[edit] Relationship to the Big Bang[edit]

Biomechanics Page of one of the first works of Biomechanics (De Motu Animalium of Giovanni Alfonso Borelli) Word history[edit] The word "biomechanics" (1899) and the related "biomechanical" (1856) were coined by Nikolai Bernstein[citation needed] from the Ancient Greek βίος bios "life" and μηχανική, mēchanikē "mechanics", to refer to the study of the mechanical principles of living organisms, particularly their movement and structure.[3] Method[edit] Usually biological systems are much more complex than man-built systems. Numerical methods are hence applied in almost every biomechanical study. Subfields[edit] Applied subfields of biomechanics include: Sports biomechanics[edit] In sports biomechanics, the laws of mechanics are applied to human movement in order to gain a greater understanding of athletic performance and to reduce sport injuries as well. Continuum biomechanics[edit] Biomaterials are classified in two groups, hard and soft tissues. Biofluid mechanics[edit] Biotribology[edit] History[edit]

Helpful Hypnosis Downloads Golden Ratio by Mark Freitag Most people are familiar with the number Pi, since it is one of the most ubiquitous irrational numbers known to man. But, there is another irrational number that has the same propensity for popping up and is not as well known as Pi. This wonderful number is Phi, and it has a tendency to turn up in a great number of places, a few of which will be discussed in this essay. One way to find Phi is to consider the solutions to the equation When solving this equation we find that the roots are x = ~ 1.618... or x= We consider the first root to be Phi. Phi = or Phi = We can use a spreadsheet to see that these two series do approximate the value of Phi. Or, we can show that the limit of the infinite series equals Phi in a more concrete way. Squaring both sides we have But this leads to the equation which in turn leads to and this has Phi as one of its roots. I have creted a GSP script for dividing a segment (given its endpoints) into the Golden ratio. We can also form a Golden Ellipse.

Leonardo da Vinci Leonardo is revered for his technological ingenuity. He conceptualised flying machines, an armoured vehicle, concentrated solar power, an adding machine,[7] and the double hull, also outlining a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime,[nb 2] but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded.[nb 3] He made substantial discoveries in anatomy, civil engineering, optics, and hydrodynamics, but he did not publish his findings and they had no direct influence on later science.[8] Life Childhood, 1452–1466 Leonardo's earliest known drawing, the Arno Valley (1473), Uffizi Verrocchio's workshop, 1466–1476 Professional life, 1476–1513 In 1482 Leonardo, who according to Vasari was a most talented musician,[25] created a silver lyre in the shape of a horse's head.

The Cosmic Tuning Device Get a set of "Mack's" earplugs the good gooey ones that don't bother the ear because they are uncomfortable which some earplugs do. When you go to sleep put these in, be sure to oxygenate the body before you fall to sleep every night, this is fuel for the astral body. 15 minutes worth of breathing air through the mouth and forcing it into the stomach. Put your hand on your stomach to be sure you are putting air into you stomach and not into you chess. Concntrate on your breath doing this, this will also still/steal you mind.

Celestial coordinate system In astronomy, a celestial coordinate system is a system for specifying positions of celestial objects: satellites, planets, stars, galaxies, and so on. Coordinate systems can specify a position in 3-dimensional space, or merely the direction of the object on the celestial sphere, if its distance is not known or not important. Coordinate systems[edit] Horizontal system[edit] The horizontal, or altitude-azimuth, system is based on the position of the observer on Earth, which revolves around its own axis once per sidereal day (23 hours, 56 minutes and 4.091 seconds) in relation to the "fixed" star background. Equatorial system[edit] Equirectangular plot of declination vs right ascension of stars brighter than apparent magnitude 5 relative to the modern constellations, ecliptic and Milky Way (fuzzy band). The equatorial coordinate system is centered at Earth's center, but fixed relative to distant stars and galaxies. Ecliptic system[edit] Galactic system[edit] Supergalactic system[edit] or
