Lie Detector or Polygraph
From Wikipedia, the free encyclopedia




A polygraph (commonly yet incorrectly referred to as a lie detector) is a device that measures and records several physiological variables such as blood pressure, pulse, respiration and skin conductivity while the subject is asked a series of questions. The measurements are posited to be indicators of anxiety that accompanies the telling of lies. Thus, measured anxiety is equated with telling untruths. However, if the subject exhibits anxiety for other reasons, or can control his anxiety level voluntarily, a measured response can result in unreliable conclusions. A polygraph test is also questionably used as a psychophysiological detection of deception (PDD) examination.




Polygraph results are sometimes recorded on a chart recorder

Nystagmus


Nystagmus is an involuntary eye movement which usually results in some degree of visual loss. The degree and direction of eye movement, amount of visual loss and resulting impairment varies greatly from person to person. This website has been created by the American Nystagmus Network, Inc., a nonprofit organization established in February, 1999 to serve the needs and interests of those affected by Nystagmus.

Plankton
From Wikipedia, the free encyclopedia
Jump to: navigation, search




Plankton are defined as any drifting organism that inhabits the water column of oceans, seas, and bodies of fresh water. They are widely considered to be some of the most important organisms on Earth, due to the food supply they provide to most aquatic life.

Quercetin

Quercetin     From Wikipedia, the free encyclopedia

Quercetin is a flavonoid and more specifically a flavonol. It is the aglycone form of a number of other flavonoid glycosides, such as rutin and quercitrin found in citrus fruit. Quercetin is found to be the most active of the flavonoids in studies,[citation needed] and many medicinal plants owe much of their activity to their high quercetin content. Quercetin has demonstrated significant anti-inflammatory activity because of direct inhibition of several initial processes of inflammation. For example, it inhibits both the manufacture and release of histamine and other allergic/inflammatory mediators. In addition, it exerts potent antioxidant activity and vitamin C-sparing action.

Quercetin forms the glycosides quercitrin and rutin together with rhamnose and rutinose respectively.

Quercetin also shows remarkable anti-tumour properties. A recent study in the British Journal of Cancer shows that when treated with a combination of quercetin and ultrasound at 20 KHz for 1 minute duration, skin and prostate cancers show a 90% mortality within 48 hours with no visible mortality of normal cells. Note that ultrasound also promotes topical absorption by up to 1,000 times making the use of topical quercetin and ultrasound wands an interesting proposition.

Quercetin may have positive effects in combating or helping to prevent cancer, prostatitis, heart disease, cataracts, allergies/inflammations, and respiratory diseases such as bronchitis and asthma.

Foods rich in quercetin include apples, black & green tea, onions (higher concentrations of quercetin occur in the outermost rings[1]), red wine, red grapes, citrus fruits, broccoli & other leafy green vegetables, cherries, and a number of berries including raspberry, bog whortleberry (158 mg/kg, fresh weight), lingonberry (74 and 146 mg/kg), cranberry (83 and 121 mg/kg), chokeberry (89 mg/kg), sweet rowan (85 mg/kg), rowanberry (63 mg/kg), sea buckthorn berry (62 mg/kg), crowberry (53 and 56 mg/kg),[1] and the fruit of the prickly pear cactus. A study[2] by the University of Queensland, Australia, has also indicated the presence of quercetin in varieties of honey, including honey derived from eucalyptus and tea tree flowers.[3]

In plants, it is a naturally-occurring polar auxin transport inhibitor.

Recent studies have supported that quercetin can help men with chronic prostatitis, possibly because of its action as a mast cell inhibitor.

Science


Science, in the broadest sense, refers to any system of objective knowledge. In a more restricted sense, science refers to a system of acquiring knowledge based on the scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines:

    * Natural sciences, which study natural phenomena, including biological life;
    * Social sciences, which study human behavior and societies

These fields are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being tested for its validity by other researchers working under the same conditions.

Mathematics is sometimes classified in a third grouping, called formal science, having both similarities and differences with the natural and social sciences. It is similar to other disciplines in that it involves a careful, systematic study of an area of knowledge; it is different because of its method of verifying its knowledge, using a-priori rather than empirical methods. Mathematics as a whole is vital to the sciences; indeed, major advances in mathematics have often led to critical advances in the physical and biological sciences. Certain mathematical approaches are indispensable for the formation of hypotheses, theories, and laws, both in discovering and describing how things work (natural sciences) and how people think and act (social sciences).

Science as defined above is sometimes termed pure science in order to differentiate it from applied science, the latter being the application of scientific research to specific human needs.

Too late Neilepus!  ;D

Buy that uaj...I think Science has been Scited before...




Science in the broadest sense refers to any system of objective knowledge. In a more restricted sense, science refers to a system of acquiring knowledge based on the scientific method, as well as to the organized body of knowledge humans have gained by such research. This article focuses on the latter sense of the word.

Fields of science are commonly classified along two major lines:

    * Natural sciences, which study natural phenomena
    * Social sciences, which study human behavior and societies

Whether mathematics is a science is a matter of perspective. It is similar to other sciences in that it is a careful, systematic study of an area of knowledge — specifically, it focuses on a priori knowledge. Mathematics as a whole is vital to the sciences — indeed, major advances in mathematics have often led to major advances in other sciences. Certain aspects of mathematics are indispensable for the formation of hypotheses, theories, and laws, both in discovering and describing how things work (natural sciences) and how people think and act (social sciences).

Science as defined above is sometimes termed pure science in order to differentiate it from applied science, the latter being the application of scientific research to human needs.

Water Fountain

The modern drinking fountain was invented and then manufactured in the early 1900s by two men and the respective company each man founded: Halsey Willard Taylor and the Halsey Taylor Company; and Luther Haws and the Haws Sanitary Drinking Faucet Co. These two companies changed how water was served in public places.

X-fragile syndrome


What Is Fragile X?

Fragile X syndrome is the leading cause of inherited developmental and mental impairment.  It is a genetic condition that is caused by a change in the genetic code of a single gene on the X chromosome. This defect inhibits the body's ability to produce a protein called FMRP.

Messages that must be sent and received for proper brain development and functioning are disrupted when this protein is missing. When the gene is altered, it can cause developmental delays and mild to severe learning disabilities including mental retardation.

Most children with fragile X appear completely typical at birth, but gradually, developmental characteristics of the condition become evident.

Yellow
From Wikipedia, the free encyclopedia


Yellow is any color of light that stimulates both the red and green cone cells of the retina, but not the blue cone cells. Light with a wavelength of 565–590 nm is yellow, though light with both red frequencies and green frequencies, such as mixing orange and lime light, or red and green light, is also yellow, and its scientifically defined complementary color in terms of color mixing using light is blue.

AIBO
From Wikipedia, the free encyclopedia


AIBO (Artificial Intelligence roBOt, also means "love" or "attachment" in Japanese, can also mean "partner") is one of several types of robotic pets designed and manufactured by Sony; there have been several different models since their introduction in 1999. Able to walk, "see" its environment via camera, and recognize spoken commands, they are considered to be autonomous robots, since they are able to learn and mature based on external stimuli from their owner or environment, or from other AIBOs. Artist Hajime Sorayama created the initial designs for the AIBO.

On January 26, 2006 Sony announced that it would discontinue AIBO and several other products. It will also stop development of the QRIO robot. AIBO will still be supported until 2013 (ERS7 model), however, and AIBO technology will continue to be developed for use in other consumer products. [1] [2] AIBOware (the name is a trademark of Sony corporation), is the title given to the software the AIBO runs on its pink Memory Stick. The Life AIBOware allows the robot to be raised from pup to fully grown adult while going through various stages of development as its owner interacts with it. The Explorer AIBOware allows the owner to interact with a fully mature robot able to understand (though not necessarily willing to obey) 100 voice commands. Without the AIBOware, the AIBO will run in what is called "clinic mode" and can only perform basic actions.

Many AIBO owners enjoy teaching their pets new behaviors by reprogramming them (in Sony's special 'R-CODE' language). However, in October 2001, Sony sent a cease-and-desist notice to the webmaster of aibopet.com/aibohack.com, demanding that he stop distributing code that was retrieved by bypassing the copy prevention mechanisms of the robot. Eventually, in the face of many outraged AIBO owners, see the protest letter, Sony released a programmer's kit for 'non-commercial' use. The kit has now been expanded into three distinct tools: R-CODE, AIBO Remote Framework, and the OPEN-R SDK. These three tools are combined under the name AIBO SDE (Software Development Environment). All of these tools are free to download and can be used for commercial or non-commercial use (Except for the OPEN-R SDK, which is specifically for non-commercial use). Since the first release of OPEN-R, several AIBO programming tools have been developed by university labs, including URBI, Tekkotsu, Pyro and Cognitive Vision.


The AIBO has seen use as an inexpensive platform for artificial intelligence research, because it integrates a computer, vision system, and articulators in a package vastly cheaper than conventional research robots. The RoboCup autonomous soccer competition has a "Sony Four-Legged Robot League" in which numerous institutions from around the world participate. Competitors program a team of AIBO robots to play games of autonomous robot soccer against other competing teams.




AIBO's complete vision system uses the SIFT algorithm, to recognise its charging station. The newest versions are equipped with a Wi-Fi connection, allowing them to send the pictures they take via email. As a result, the Roblog originated.

AIBO's sounds were programmed by Japanese DJ/avant-garde composer Nobukazu Takemura, considered by many to be highly skilled at fusing mechanic and organic concepts, and the bodies of the "3x" series (Latte and Macaron, the round-headed AIBOs released in 2001) were designed by visual artist Katsura Moshino.

Binary star

http://en.wikipedia.org/wiki/Binary_star




Binary star
From Wikipedia, the free encyclopedia
Jump to: navigation, search
 
Artist's impression of a binary system consisting of a black hole, with an accretion disc around it, and a main sequence star.A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined by extrapolations made from the observation of binaries.

Binary stars are not the same as optical double stars, which appear to be close together as seen from Earth, but may not be bound by gravity. Binary stars can either be distinguished optically (visual binaries) or by indirect techniques, such as spectroscopy. If binaries happen to orbit in a plane containing our line of sight, they will eclipse each other; these are called eclipsing binaries.

Systems consisting of more than two components, known as multiple stars, are also not uncommon and are generally classified under the same name. The components of binary star systems can exchange mass, bringing their evolution to stages that single stars cannot attain. Examples of binaries are Algol (an eclipsing binary), Sirius, and Cygnus X-1 (of which one member is probably a black hole).


YES INDEEDY, I DID IT!!! YES!!!! BTW NEILY, THE YELLOW SUNFLOWERS ARE SPECTACULAR SO CHEERY AND WARM..YAYYYYYYYYYY!

Crop circle
From Wikipedia, the free encyclopedia

   

Crop circles are geometrical formations of flattened crops found in England and elsewhere. They have been found in wheat, barley, canola, rye, corn, linseed and soy.

The phenomenon itself was noticed in its current form after notable appearances in England in the late 1970s. Various explanations were offered for the phenomenon, which soon spread around the world. In 1991, two men, Doug Bower and Dave Chorley, revealed that they had been making crop circles in England since 1978 using planks, rope, hats and wire as their only tools[1][2]. Circlemakers.org[3] a UK-based arts collective founded by John Lundberg have been creating complex crop circles since the early 1990s. [4].

Despite the evidence that crop circles are of human origin, various paranormal theories continue to enjoy some currency, although these all violate Occam's Razor.[5]





Here's one I made earlier !!

Encyclopædia Britannica
From Wikipedia, the free encyclopedia

The Encyclopædia Britannica is a general encyclopedia published by Encyclopædia Britannica Inc., a privately held company owned by Swiss billionaire and actor Jacqui Safra. The Britannica is the oldest continuously published English-language encyclopedia.[1] Its articles are written by a dedicated staff of 19 full-time editors and by over four thousand contributors, who typically contribute to a single subject in which they are recognized authorities. The articles are targeted at educated adult readers,[2] although simplified versions have been developed. Despite its name and preference for British spelling, the Britannica has been published in the United States since 1901.[2]

The Britannica was first published from 1768–71 in three volumes under the title Encyclopædia Britannica, or, A dictionary of arts and sciences, compiled upon a new plan, partly as a conservative reaction to the provocative French Encyclopédie of Diderot published 1751-66.[1] Although the Britannica was published in a market with established English-language encyclopedias,[1] it quickly grew in popularity and size, reaching 20 volumes by the publication of its third edition in 1801. Its rising stature allowed the Britannica to recruit eminent authorities for its articles, which has continued for the past two centuries. Up to the 11th edition, the Britannica published new research and scholarly theories; in particular, the 9th and 11th editions (published in 1875-1889 and in 1911, respectively) are regarded as landmark encyclopedias for scholarship. However, beginning with the 11th edition, the American owners of the Britannica chose to simplify and shorten its articles, making them more accessible to lay-readers, with the goal of broadening its North American market. In 1933, the Britannica became the first encyclopedia to adopt a "continuous revision" policy in which the encyclopedia would be revised and reprinted every year, and every article checked at least twice per decade.

Beginning with the current 15th edition, the Britannica adopted a unique three-part structure: a Micropædia of roughly 65,000 short articles (typically with no references, no named authors and fewer than 750 words), a Macropædia of roughly 700 long articles (each article having 2-310 pages, references and named contributors), and a single Propædia volume that seeks to give a hierarchical outline of all human knowledge. The articles of the Micro- and Macropædia are both listed in alphabetical order, but it is intended[3] that readers interested in a given subject will study the Propædia first to grasp its context, then use Micropædia both as a tool to briefly introduce concepts and to find appropriate, more thorough information within the Macropædia articles. The Index was removed from the first 15th edition (1974) but was restored in the second (1985), in response to reader requests. The size of the Britannica has remained constant over the last 70 years, with roughly 40 million words addressing roughly half a million topics.[4]

An increasing number of alternative information sources have reduced the popular demand for print encyclopedias significantly. The Britannica has weathered this competition on the strength of its reputation, and by lowering its price point, reducing its costs drastically and developing electronic versions on CD-ROM, DVD and the World Wide Web. Although its reputation for excellence has been questioned recently by several respectable critics, such criticisms have been challenged vigorously by the Britannica's management.

Ganoderma lucidum


Will this ancient oriental herbal remedy join 'our' Medicine?


Língzhī (traditional Chinese: 靈芝; simplified Chinese: 灵芝; Japanese: reishi; Korean: yeongji, hangul: 영지) is the name for one form of the mushroom Ganoderma lucidum.
This fungal species has a worldwide distribution in both tropical and temperate geographical regions, including North and South America, Africa, Europe, and Asia, growing as a parasite or saprophyte on a wide variety of trees.[1] Ganoderma lucidum enjoys special veneration in Asia, where it has been used in traditional Chinese medicine as a herbal medicine for more than 4,000 years, making it one of the oldest mushrooms known to have been used in medicine.

The word lingzhi, in Chinese, means "herb of spiritual potency" and has also been described as "mushroom of immortality".[1] Because of its presumed health benefits and apparent absence of side-effects, it has attained a reputation in the East as the ultimate herbal substance. Lingzhi has now been added to the American Herbal Pharmacopoeia and Therapeutic Compendium.

Thomas Hancock was an English inventor who founded the British rubber industry. Hancock invented the masticator, a machine that shredded rubber scraps, allowing rubber to be recycled after being formed into blocks or rolled into sheets.

The Masticator

In 1820, Thomas Hancock patented elastic fastenings for gloves, suspenders, shoes and stockings. In the process of creating the first elastic fabrics, Hancock found himself wasting considerable rubber. He invented the masticator to help conserve rubber.

Hancock kept notes during the process of invention. He made the following comments: "pieces with fresh cut edges would perfectly unite; but the outer surface, which had been exposed, would not unite... it occurred to me that if minced up very small the amount of fresh-cut surface would be greatly increased and by heat and pressure might possibly unite sufficiently for some purposes".

Thomas Hancock Invents A Pickle?
An eccentric Thomas Hancock initially did not choose to patent his machine, instead he gave it the deceptive name of "pickle" so that no one else would know what it was.

The first masticator was a wooden machine that used a hollow cylinder studded with teeth - inside the cylinder was a studded core that was hand cranked.
