Euglena's have plant and animal features
Euglena are a common group of unicellular protists, of the class Euglenoidea of the phylum Euglenophyta. They are single-celled organisms. Currently, over 1000 species of Euglena have been described. Marin et al. (2003) revised the genus to include several species without chloroplasts, formerly classified as Astasia and Khawkinea. Euglena sometimes can be considered to have both plant and animal features.

Mark Twain invented the self pasting scrapbook in 1872
Mark Twain was a lifelong creator and keeper of scrapbooks. He took them with him everywhere and filled them with souvenirs, pictures, and articles about his books and performances. But in time, he grew tired of the lost glue, rock-hard paste, and the swearing that resulted from the standard scrapbook process. So, he came up with the idea of printing thin strips of glue on the pages to make updates neat and easy to do. In 1872, he patented his “self-pasting” scrapbook, and by 1901, at least 57 different types of his albums were available. It would be his only invention that ever made money. Inspired by his invention, this interactive scrapbook tells Twain’s life story through a collection of texts, photos, illustrations, and clippings from his day. To begin exploring, click one of the chapters to the right.

The Arctic Terns migration is the longest regular migration known
The Arctic Tern (Sterna paradisaea) is a seabird of the tern family Sternidae. This bird has a circumpolar distribution, breeding colonially in Arctic and sub-Arctic regions of Europe, Asia, and North America (as far south as Brittany and Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates from its northern breeding grounds to the oceans around Antarctica and back (about 24,000 miles) each year. This is the longest regular migration by any known animal. The arctic tern flies as well as glides through the air, performing almost all of its tasks in the air. The arctic tern lands once every one to three years (depending on their mating cycle) to nest; once they have finished nesting they take to the sky for another long southern migration.

A tiny animal called Hydra doesnt age
Hydra is a genus of simple fresh-water animals possessing radial symmetry. Hydras are predatory animals belonging to the phylum Cnidaria and the class Hydrozoa. They can be found in most unpolluted freshwater ponds, lakes and streams in the temperate and tropical regions by gently sweeping a collecting net through weedy areas. They are usually a few millimeters long and are best studied with a microscope. Biologists are especially interested in hydras due to their regenerative ability and because they appear to undergo senescence (aging) very slowly, if at all.

The largest know pearl weights 6.4kg
The largest pearl known, was found in the Philippines in 1934. It is a naturally-occurring, non-nacreous, calcareous concretion from a giant clam. Because it did not grow in a pearl oyster it is not pearly, instead it has a porcellaneous surface. In other words, it is glossy like a china plate. Other pearls from giant clams are known to exist, but this is a particularly large one. The pearl weighs 14 lb (6.4 kg) and was supposedly first discovered by an anonymous Filipino Muslim diver off the island of Palawan in 1934. According to the legend as it is currently told, a Palawan chieftain gave the pearl to Wilbur Dowell Cobb in 1936 as a gift for having saved the life of his son. The pearl had been named the "Pearl of Allah" by the Muslim tribal chief, because it resembled a turbaned head. Another even more elaborate legend says that this object is actually the Pearl of Lao-Tzu, a cultured pearl created with a carved amulet and then supposedly progressively grafted into several giant clams, before supposedly being lost due to a shipwreck in 1745. [6] This legend has been discredited, however because this pearl is indeed the product of a giant clam, Tridacna gigas, which cannot be grafted. The pearl is also a whole pearl, not a mabe pearl, and whole pearl culturing technology is only 100 years old. [7]

Mexican jumping beans jump because of a larva inside
After the egg has hatched, the larva eats away the inside of the bean, making a hollow for itself. It attaches itself to the bean with many silk threads.
The larva may live for months inside the bean with varying periods of dormancy. If the larva has adequate conditions such as moisture, it will live long enough to go into a pupal stage. Normally in the spring, the moth will force its way out of the bean through a round "trap door", leaving behind the pupal casing. The small, silver and gray-colored moth will live for only a few days.
The beans jump as a survival measure in order to protect the larvae from the heat, which can cause them to dry out. The ultraviolet rays from the sun stimulate them to jump, even in cool temperatures, but leaving them in the sun for extended periods will dehydrate and kill them.
Lake Baikal is the largest fresh water lake in the world
At 1,637 meters (5,370 ft), Lake Baikal is the deepest lake in the world,[4] and the largest freshwater lake in the world by volume.[5] However, Lake Baikal contains less than one third the amount of water as the Caspian Sea, which is the largest lake in the world. Like Lake Tanganyika, Lake Baikal was formed in an ancient rift valley and therefore, is long and crescent-shaped with a surface area (31,494 km2/12,160 sq mi), less than that of Lake Superior or Lake Victoria. Baikal is home to more than 1,700 species of plants and animals, two thirds of which can be found nowhere else in the world[6] and was declared a UNESCO World Heritage Site in 1996.[7] At more than 25 million years old, it is the oldest lake in the world.[5]

Termites use protozoa (a micro-organism) to digest wood
All termites eat cellulose in its various forms as plant fibre. Cellulose is a rich energy source (as demonstrated by the amount of energy released when wood is burned), but remains difficult to digest. Termites rely primarily upon symbiotic protozoa (metamonads) such as Trichonympha, and other microbes in their gut to digest the cellulose for them and absorb the end products for their own use. Gut protozoa, such as Trichonympha, in turn rely on symbiotic bacteria embedded on their surfaces to produce some of the necessary digestive enzymes. This relationship is one of the finest examples of mutualism among animals. Most so called "higher termites", especially in the Family Termitidae, can produce their own cellulase enzymes. However, they still retain a rich gut fauna and primarily rely upon the bacteria. Due to closely related bacterial species, it is strongly presumed that the termites' gut flora are descended from the gut flora of the ancestral wood-eating cockroaches, like those of the genus Cryptocercus.

Many smalls spider use silk threads for ballooning (drift away on the wind)
Many small spiders use silk threads for ballooning, the scientific term for the dynamic kiting [1] [2] spiderlings (mostly) use for dispersal. They extrude several threads into the air and let themselves become carried away with upward winds. Although most rides will end a few meters later, it seems to be a common way for spiders to invade islands. Many sailors have reported that spiders have been caught in their ship's sails, even when far from land.

The Texas leafcutter ant cultivates fungus
The Atta texana, is a fungus-farming ant species chiefly found in Texas and Louisiana in the U.S.. It can also be found in a few northeastern states of Mexico. [1] It harvests leaves from over 200 types of plants and is considered a major pest to the state's agricultural interests, as it can defoliate a citrus tree in less than 24 hours. Every colony has several queens and up to 2 million workers.

In some countries cormorants are trained by fisherman to catch fish
Humans have historically exploited cormorants' fishing skills, in China, Japan, and Macedonia, where they have been trained by fishermen. A snare is tied near the base of the bird's throat, which allows the bird only to swallow small fish. When the bird captures and tries to swallow a large fish, the fish is caught in the bird's throat. When the bird returns to the fisherman's raft, the fisherman helps the bird to remove the fish from its throat. The method is not as common today, since more efficient methods of catching fish have been developed.

The name of Australia comes from "terra australis incognita" translation "unknown land of the south"
The name Australia is derived from the Latin Australis, meaning "Southern". Legends of an "unknown land of the south" (terra australis incognita) date back to Roman times and were commonplace in medieval geography but were not based on any documented knowledge of the continent. In 1521 Spaniards were among the first Europeans to sail the Pacific Ocean. The first use of the word Australia in English was in 1625, in "A note of Australia del Espiritu Santo, written by Master Hakluyt", published by Samuel Purchas in Hakluytus Posthumus.

Mapmakers insert incorrect entries to see when someone illegal copies their work, they are called "copyright traps"
Fictitious entries, also known as fake entries, Mountweazels, and Nihilartikels, are deliberately incorrect entries or articles in reference works such as dictionaries, encyclopedias, maps and directories. Entries in reference works normally originate from a reliable external source, but no such source exists for a fictitious entry.
Fictitious entries can be humorous hoaxes intended to be more or less quickly recognized as false by the reader or copyright traps deliberately inserted into a work to facilitate detection of copyright infringement or plagiarism.

All male mules and most female mules are infertile
A mule is the offspring of a male donkey and a female horse.[1] Historically, and today in technical jargon, "mule" refers to the infertile offspring of any two animals of different species. Horses and donkeys are different species, with different numbers of chromosomes. Of the two F1 hybrids between these two species, a mule is easier to obtain than a hinny (the offspring of a male horse and a female donkey). All male mules and most female mules are infertile.

The largest known organism (a fungal colony) spans 8.9km² (2,200 acres)
Armillaria ostoyae is a fungus commonly known as a Honey mushroom, and sometimes called Shoestring Rot.
This is the most common variant in the western U.S., of the group of species that all used to share the name Armillaria mellea. Armillaria ostoyae is quite common on both hardwood and conifer wood in forests west of the Cascade crest. The mycelium attacks the sapwood and is able to travel great distances under the bark or between trees in the form of black rhizomorphs ("shoestrings").
The disease is of particular interest to forest managers, as the species is highly pathogenic to a number of commercial softwoods, notably Douglas-fir (Pseudotsuga menziesii), true firs (Abies spp.) and Western Hemlock (Tsuga heterophylla). A commonly prescribed treatment is the clearcutting of an infected stand followed by planting with more resistant species such as Western redcedar (thuja plicata) or deciduous seedlings. The removal of stumps (stumping) has been used to prevent contact between infected stumps and newer growth resulting in lower infection rates. However, it is unknown if the lower infection rates will persist as roots of young trees extend closer to the original inoculum from the preceding stand. The use of another fungus, Hypholoma fasciculare has been shown in early experiments to competitively exclude Armillaria ostoyae in both field and laboratory conditions, but further experimentation is required to establish the efficacy of this treatment.
A mushroom of this type in the Malheur National Forest in the Strawberry Mountains of eastern Oregon, U.S. was found to be the largest fungal colony in the world, spanning 8.9 km² (2,200 acres) of area. This organism is estimated to be 2,400 years old. The fungus was written about in the April 2003 issue of the Canadian Journal of Forest Research. While an accurate estimate has not been made, the total mass of the colony may be as much as 605 tons. If this colony is considered a single organism, then it is the largest known organism in the world by area, and rivals the aspen grove "Pando" as the known organism with the highest living biomass.
In 1992, a relative of the Strawberry Mountains clone was discovered in southwest Washington state. It covers about 6 km² (1500 acres).
Another "humongous fungus" is a specimen of Armillaria bulbosa found at a site near Crystal Falls, Michigan covers 0.15 km² (37 acres), and was published in Nature.[1]

Lawn darts are banned in Canada
Send in by: TARZ1977
On December 19, 1988, the Consumer Product Safety Commission banned lawn darts from sale in the United States.[1] Shortly after, in 1989, they were also banned in Canada.[2] Lawn darts, used in an outdoor game, have been responsible for the deaths of three children.[1]
Safety lawn darts can be found in a few stores around the United States.

The name of the Michelin man is Bibendum (it is latin for something like "time to drink")
The 1898 poster showed him offering the toast Nunc est bibendum ("Cheers!" or "Now is the time to drink" in Latin), to his scrawny competitors with a glass full of road hazards, with the title and the tag C'est à dire: À votre santé. Le pneu Michelin boit l'obstacle ("That is to say, to your health: The Michelin tyre drinks up obstacles"). It is unclear when the word "Bibendum" came to be the name of the character himself. At the latest, it was in 1908, when Michelin commissioned Curnonsky to write a newspaper column signed "Bibendum".

Thomas Edison had a tatoo of 5 dots (like on a dice) on his left forearm
According to a 1911 policy with the Mutual Life Insurance Company of New York, Edison had five dots tattooed on his left forearm. No one knew what the dots meant.Interestingly, Edison was credited for inventing the basic tattoo machine. In 1876, he patented the Stencil-Pens, an engraving device that many years later was modified by Samuel O’Reilly to make the world’s first tattoo machine.
Though it would’ve been a neat thing, there was simply no evidence that Edison used his invention to give himself a tattoo.

The blood in the original psycho film is in fact chocolate syrup
The soundtrack of screeching violins, violas, and cellos was an original all-strings piece by composer Bernard Herrmann entitled "The Murder." Hitchcock originally wanted the sequence (and all motel scenes) to play without music,[13] but Herrmann begged him to try it with the cue he had composed. Afterwards, Hitchcock agreed that it vastly intensified the scene, and he nearly doubled Herrmann's salary.[4][14][15] The blood in the scene is in fact chocolate syrup, which shows up better on black-and-white film, and has more realistic density than stage blood.[1] The sound of the knife entering flesh was created by plunging a knife into a melon.[16][17]

The microwave was invented when Percy Spencer noticed a chocolate bar in his pocket melted nearby an active radar
Cooking food with microwaves was discovered accidentally in the 1940s. Percy Spencer, a self-taught engineer, was building magnetrons for radar sets with the company Raytheon. He was working on an active radar set when he noticed that a peanut chocolate bar he had in his pocket started to melt. The radar had melted his candy bar with microwaves. The first food to be deliberately cooked with Spencer's microwave was popcorn, and the second was an egg, which exploded in the face of one of the experimenters.[1] To verify his finding, Spencer created a high density electromagnetic field by feeding microwave power into a metal box from which it had no way to escape. When food was placed in the box with the microwave energy, the temperature of the food rose rapidly.

In medieval times narwhal horns were sold as unicorn horns for loads of money
In Inuit legend, the narwhal's tusk was created when a woman with a harpoon rope tied around her waist was dragged into the ocean after the harpoon had struck a large narwhal. She was transformed into a narwhal herself, and her hair twisted around in the water until it became the characteristic spiral narwhal tusk. [15]
Some medieval Europeans believed narwhal tusks to be the horns from the legendary unicorn.[16] As these horns were considered to have magic powers, such as the ability to cure poison and melancholia[17], Vikings and other northern traders were able to sell them for many times their weight in gold. The tusks were used to make cups that were thought to negate any poison that may have been slipped into the drink. During the 16th century, Queen Elizabeth received a carved and bejeweled narwhal tusk for £10,000—the cost of a castle (approximately £1.5—2.5 Million in 2007, using the retail price index[18]). The tusks were staples of the cabinet of curiosities.
The truth of the tusk's origin developed gradually during the Age of Exploration, as explorers and naturalists began to visit Arctic regions themselves. In 1555, Olaus Magnus published a drawing of a fish-like creature with a horn on its forehead.
Herman Melville wrote a section on the narwhal in Moby Dick. In it, he claims that a narwhal tusk hung for "a long period" in Windsor Castle after Sir Martin Frobisher had given it to Queen Elizabeth.
Giraffes have double the blood pressure of an average mammal
Modifications to the giraffe's structure have evolved, particularly to the circulatory system. A giraffe's heart, which can weigh up to 10 kg (22 lb) and measure about 60 cm (2 ft) long, must generate approximately double the normal blood pressure for an average large mammal to maintain blood flow to the brain. In the upper neck, a complex pressure-regulation system called the rete mirabile prevents excess blood flow to the brain when the giraffe lowers its head to drink. Conversely, the blood vessels in the lower legs are under great pressure (because of the weight of fluid pressing down on them). In other animals such pressure would force the blood out through the capillary walls; giraffes, however, have a very tight sheath of thick skin over their lower limbs which maintains high extravascular pressure in the same way as a pilot's g-suit.

Cheese helps against plaque
Several mechanisms have been proposed to explain cheese's anticariogenic effect (11,31,32). Cheese may buffer or neutralize plaque acids; stimulate saliva flow which has caries-reducing properties; and reduce demineralization and/or promote remineralization by protein, calcium, and phosphorus. The buffering effect of protein in cheese (e.g., casein phosphopeptides) on acid formation in dental plaque and the promotion of food clearance by cheese-induced saliva flow are the most popularly held explanations for cheese's beneficial effect on dental caries (31). Both experimental animal and human epidemiological studies demonstrate that calcium and phosphate in cheese may be partly responsible for this food's ability to remineralize tooth enamel (11,31,32). When dental plaque samples were obtained from British adults before and 5 minutes after intake of cheese cubes or cheese-containing meals (e.g., pasta with cheese sauce), plaque calcium concentrations were significantly higher in subjects consuming cheese than in those who did not consume this food (41). This finding led the researchers to suggest that consuming cheese either alone or as part of a meal increases plaque calcium, which helps to reduce or prevent decreases in plaque pH levels and promote remineralization of tooth enamel (41).

Fresh milk may protect children against asthma and hay fever
The results of the European "Parsifal Study", conducted on about 15,000 children, show that regular consumption of fresh milk directly from the farm may protect children against asthma and hay fever. The control sample consisted of children growing up on farms, children from rural and suburban environments, and Waldorf school students. The study, which was led by the Institute for Social and Preventive Medicine at the University of Basel, was published in the journal "Clinical and Experimental Allergy" in May 2007.

The skin underneath the fur of a tiger is also stripped
. The pattern of stripes is unique to each animal, and thus could potentially be used to identify individuals, much in the same way as fingerprints are used to identify people. This is not, however, a preferred method of identification, due to the difficulty of recording the stripe pattern of a wild tiger. It seems likely that the function of stripes is camouflage, serving to help tigers conceal themselves amongst the dappled shadows and long grass of their environment as they stalk their prey. The stripe pattern is found on a tiger's skin and if shaved, its distinctive camouflage pattern would be preserved. Like other big cats, tigers have a white spot on the backs of their ears.

The sun was so hot the day Disneyland opened, it made the asphalt of main street melt
On July 17, 1955, when Disneyland finally opened to the public, the image that is conjured when we think of Disneyland is far from opening day. The park was overcrowded as tickets - which were invitational for the first day - were faked and sold on the black market, with all major nearby roads and highways jam packed. The sun was so hot that ladies' high-heels were sinking into the melting asphalt of Main Street. A gas leak in Fantasyland caused Adventureland, Frontierland and Fantasyland to close from the afternoon, and parents where throwing children over the shoulders of crowds to get in queue for rides now world-famous like Dumbo. Vendors ran out of food, and the park got such bad press for opening day that Walt Disney invited members of the press back for a private 'second day' to experience the true Disneyland, whereafter Walt held a party in the Disneyland Hotel. Walt and his executives forever referred to the first day as Black Sunday.

A blind man (Ralph Teetor) invented the cruisecontrol
Ralph Teetor (1890-1982) was a prolific (and blind) inventor who invented cruise control. He was also the longtime president of the very successful automotive parts manufacturer The Perfect Circle Co. Corporation in Hagerstown, Indiana, a manufacturer of piston rings. He graduated from the University of Pennsylvania in 1912, which surprised the faculty because they originally thought that he couldn't do the required work.
Teetor's highly developed sense of touch proved its advantage in developing a technique for balancing steam turbine rotors used in torpedo-boat destroyers. Dynamic balancing of large components had puzzled others before Teetor solved the problem.
Teetor was inspired to invent cruise control one day while riding with his lawyer. The lawyer would slow down while talking and speed up while listening. This rocking motion so annoyed Teetor that he was determined to invent a speed control device.

Viper venom doesn't contain neurotoxins but its venom makes your blood wont clotter, its victims bleed to death
Viperid venoms typically contain an abundance of protein-degrading enzymes, called proteases, that produce symptoms such as pain, strong local swelling and necrosis, blood loss from cardiovascular damage complicated by coagulopathy, and disruption of the blood clotting system. Death is usually caused by collapse in blood pressure. This is in contrast to elapid venoms that generally contain neurotoxins that disable muscle contraction and cause paralysis. Death from elapid bites usually results from asphyxiation because the diaphragm can no longer contract. However, this rule does not always apply: some elapid bites include proteolytic symptoms typical of viperid bites, while some viperid bites produce neurotoxic symptoms.[5]

Komodo dragons have 57 virulent bacteria in their saliva
Komodo dragons also possess virulent bacteria in their saliva, of which more than 28 Gram-negative and 29 Gram-positive strains have been isolated.[25] These bacteria cause septicemia in their victim; if an initial bite does not kill the prey animal and it escapes, it will commonly succumb within a week to the resulting infection. The most harmful bacterium in Komodo dragon saliva appears to be a deadly strain of Pasteurella multocida, from studies performed with laboratory mice.[26] There is no specific antidote to the bite of a Komodo dragon, but it can usually be treated by sterilizing the wounded area and giving the patient large doses of antibiotics. If not treated promptly, gangrene can quickly develop around the bite, which may require amputation of the affected area. Because the Komodo dragon appears immune to its own microbes, much research has been done searching for the antibacterial molecule(s) in the hopes of human medicinal usage.[27]

The first high heels were made for horse riding
Raised heels are stated[weasel words] to have been a response to the problem of the rider's foot slipping forward in stirrups while riding. The "rider's heel," approximately 1-1/2 inch (4 cm) high, appeared around 1500. The leading edge was canted forward to help grip the stirrup, and the trailing edge was canted forward to prevent the elongated heel from catching on underbrush or rock while backing up, such as in on-foot combat. These features are evident today in riding boots, notably cowboy boots.http://en.wikipedia.org/wiki/High_heel
in most cases swallowed gum digests as little slower as normal food, but it digests
One old wives' tale says that swallowed gum will remain in a person's stomach for up to seven years, as it is not digestable. According to several medical opinions, there seems to be little truth behind the tale. In most cases, swallowed gum will pass through the system as fast as any other food, but can be a little slower.[6] There have been a few cases where swallowing gum has required medical attention, but these cases are more or less related to chronic gum swallowers. One young boy swallowed several pieces each day and had to be hospitalized,[7] and another little girl required medical attention when she swallowed her gum and four coins, which got stuck together in her oesophagus.[8] As long as the mass of gum is small enough to pass out of the stomach, it is unlikely they will experience any problems.

Elm Farm Ollie was the first cow to fly and was also the first cow milked while flying
Elm Farm Ollie (known as "Nellie Jay" and post-flight as "Sky Queen") was the first cow to fly in an airplane, doing so on 18 February 1930, as part of the International Air Exposition in St. Louis, Missouri, United States. On the same trip, which covered 72 miles from Bismarck, Missouri, to St. Louis, she also became the first cow milked in flight. This was done ostensibly to allow scientists to observe midair effects on animals, as well as for publicity purposes. A St. Louis newspaper trumpeted her mission as being "to blaze a trail for the transportation of livestock by air."Elm Farm Ollie was reported to have been an unusually productive Guernsey cow, requiring three milkings a day and producing 24 quarts of milk during the flight itself. Wisconsin native Elsworth W. Bunce milked her, becoming the first man to milk a cow mid-flight. Elm Farm Ollie's milk was sealed into paper cartons which were parachuted to spectators below. Charles Lindbergh reportedly received a glass of the milk.
Although Elm Farm Ollie was born and raised in Bismarck, Missouri, it is largely in the dairy state of Wisconsin where her fame has lived on.
The paradise tree snake (chrysopelea paradisi) can glide
Paradise Tree Snake or Paradise Flying Snake Chrysopelea paradisi is a species of snake found in Asia. It can glide by stretching the body into a flattened strip using its ribs.

The largest canon used in combat was named Schwerer Gustav with a caliber of 800mm
Schwerer Gustav (English: Heavy Gustav) and Dora were the names of the German 80 cm K (E) railway guns. They were developed in the 1930s by Krupp in order to destroy large forts. They weighed nearly 1,350 tonnes, and could fire shells weighing seven tonnes to a range of 37 kilometers (23 miles). Designed in preparation for World War II, and intended for use against the deep forts of the Maginot Line, they were not ready for action when the Wehrmacht outflanked the line during the Battle of France. Gustav was used in the Soviet Union at the siege of Sevastopol during Operation Barbarossa. They were moved to Leningrad, and may have been intended for Warsaw. Gustav was captured by US troops and cut up. Dora was destroyed near the end of the war to avoid capture by the Red Army.
It was the largest calibre rifled weapon in the history of artillery to see actual combat, and fired the heaviest shells of any artillery piece [1]. It is only surpassed in calibre by the American 36-inch Little David mortar and a handful of earlier siege mortars that all fired smaller shells.[2]
The Nazis envisioned these "super guns" as powerful terror weapons which could smash enemy fortifications and bombard cities from incredible distances.[citation needed] However their massive size and consequent poor mobility made them of little strategic use. In fact, the incredible quantities of materials and manpower required to construct and operate such weapons, both of which might have been put to use elsewhere, meant they likely had a negative overall impact on the Nazi war effort.[citation needed]

Many famous paintings and building are made using the golden ratio
Some scholars deny that the Greeks had any aesthetic association with golden ratio. For example, Midhat J. Gazalé says, "It was not until Euclid, however, that the golden ratio's mathematical properties were studied. In the Elements (308 B.C.) the Greek mathematician merely regarded that number as an interesting irrational number, in connection with the middle and extreme ratios. Its occurrence in regular pentagons and decagons was duly observed, as well as in the dodecahedron (a regular polyhedron whose twelve faces are regular pentagons). It is indeed exemplary that the great Euclid, contrary to generations of mystics who followed, would soberly treat that number for what it is, without attaching to it other than its factual properties."[18] And Keith Devlin says, "Certainly, the oft repeated assertion that the Parthenon in Athens is based on the golden ratio is not supported by actual measurements. In fact, the entire story about the Greeks and golden ratio seems to be without foundation. The one thing we know for sure is that Euclid, in his famous textbook Elements, written around 300 B.C., showed how to calculate its value."[19] Near-contemporary sources like Vitruvius exclusively discuss proportions that can be expressed in whole numbers, i.e. commensurate as opposed to irrational proportions.
A geometrical analysis of the Great Mosque of Kairouan reveals a consistent application of the golden ratio throughout the design, according to Boussora and Mazouz.[20] It is found in the overall proportion of the plan and in the dimensioning of the prayer space, the court, and the minaret. Boussora and Mazouz also examined earlier archaeological theories about the mosque, and demonstrate the geometric constructions based on the golden ratio by applying these constructions to the plan of the mosque to test their hypothesis.
The Swiss architect Le Corbusier, famous for his contributions to the modern international style, centered his design philosophy on systems of harmony and proportion. Le Corbusier's faith in the mathematical order of the universe was closely bound to the golden ratio and the Fibonacci series, which he described as "rhythms apparent to the eye and clear in their relations with one another. And these rhythms are at the very root of human activities. They resound in man by an organic inevitability, the same fine inevitability which causes the tracing out of the Golden Section by children, old men, savages and the learned."[21]
Le Corbusier explicitly used the golden ratio in his Modulor system for the scale of architectural proportion. He saw this system as a continuation of the long tradition of Vitruvius, Leonardo da Vinci's "Vitruvian Man", the work of Leon Battista Alberti, and others who used the proportions of the human body to improve the appearance and function of architecture. In addition to the golden ratio, Le Corbusier based the system on human measurements, Fibonacci numbers, and the double unit. He took Leonardo's suggestion of the golden ratio in human proportions to an extreme: he sectioned his model human body's height at the navel with the two sections in golden ratio, then subdivided those sections in golden ratio at the knees and throat; he used these golden ratio proportions in the Modulor system. Le Corbusier's 1927 Villa Stein in Garches exemplified the Modulor system's application. The villa's rectangular ground plan, elevation, and inner structure closely approximate golden rectangles.[22]
Another Swiss architect, Mario Botta, bases many of his designs on geometric figures. Several private houses he designed in Switzerland are composed of squares and circles, cubes and cylinders. In a house he designed in Origlio, the golden ratio is the proportion between the central section and the side sections of the house.[23]
In a recent book, author Jason Elliot speculated that the golden ratio was used by the designers of the Naqsh-e Jahan Square and the adjacent Lotfollah mosque.[24]
Leonardo da Vinci's illustrations in De Divina Proportione (On the Divine Proportion) and his views that some bodily proportions exhibit the golden ratio have led some scholars to speculate that he incorporated the golden ratio in his own paintings. Some suggest that his Mona Lisa, for example, employs the golden ratio in its geometric equivalents.[25] Whether Leonardo proportioned his paintings according to the golden ratio has been the subject of intense debate. The secretive Leonardo seldom disclosed the bases of his art, and retrospective analysis of the proportions in his paintings can never be conclusive[citation needed].
Salvador Dalí explicitly used the golden ratio in his masterpiece, The Sacrament of the Last Supper. The dimensions of the canvas are a golden rectangle. A huge dodecahedron, with edges in golden ratio to one another, is suspended above and behind Jesus and dominates the composition.[26][2]
Mondrian used the golden section extensively in his geometrical paintings.[27]
A statistical study on 565 works of art of different great painters, performed in 1999, found that these artists had not used the golden ratio in the size of their canvases. The study concluded that the average ratio of the two sides of the paintings studied is 1.34, with averages for individual artists ranging from 1.04 (Goya) to 1.46 (Bellini).[28] On the other hand, Pablo Tosto listed over 350 works by well-known artists, including more than 100 which have canvasses with golden rectangle and root-5 proportions, and others with proportions like root-2, 3, 4, and 6.[29]

The russian sattalite Luna 1 missed the moon in 1959 and became the first man made satalite to orbit around the sun
Luna 1 (E-1 series), also known as Mechta (Russian: Мечта, lit.: Dream) was the first spacecraft to reach the vicinity of the Moon and the first of the Luna programme of Soviet automatic interplanetary stations successfully launched in the direction of the Moon.
While traveling through the outer Van Allen radiation belt, the spacecraft's scintillator made observations indicating that there exist a small number of high energy particles in the outer belt. The measurements obtained during this mission provided new data on the Earth's radiation belt and outer space. It was discovered that the Moon had no detectable magnetic field. The first ever direct observations and measurements of the solar wind, a strong flow of ionized plasma emanating from the Sun and streaming through interplanetary space, were performed. That ionized plasma concentration was measured to be some 700 particles per cm3 at altitudes 20-25 thousand km and 300 to 400 particles per cm3 at altitudes 100-150 thousand km.[1] The spacecraft also marked the first instance of radio communication at the half million kilometres distance.
A malfunction in the ground-based control system caused an error in the rocket's burntime, and the spacecraft missed the target and flew by the Moon at a distance of 5,900 km at the closest point. Luna 1 then became the first man-made object to reach heliocentric orbit and was then dubbed a "new planet" and renamed Mechta. Its orbit lies between those of Earth and Mars. The name "Luna-1" was applied retroactively years later. Luna-1 was originally referred to as the "First Cosmic Rocket", in reference to its achievement of escape velocity.

Ferruccio Lamborghini made tractors until Enzo Ferrari insulted him
A wealthy manufacturer of tractors and air conditioning and heating units systems after World War II, Lamborghini was an enthusiastic owner of sports cars. After owning and driving a Mercedes-Benz 300SL, a Jaguar E-Type, an Alfa Romeo 1900, a Lancia Aurelia B20 and a Maserati 3500GT, he bought his first Ferrari, a 250GT. He became a Ferrari enthusiast, eventually owning three. However, he had recurring clutch problems, and eventually brought his complaints to Enzo Ferrari. Ferrari insulted Lamborghini, effectively stating that a tractor manufacturer was not qualified to criticize Ferraris. Affronted by Ferrari's reaction, Lamborghini began to repair his clutch himself, at which point he noticed that some of the clutch components were the same as the ones he used on his tractors. He replaced the clutch with one built to a stronger specification, which solved the problem. Lamborghini then decided to build faster and more reliable cars than Ferrari and to prove that supercars did not have to be as temperamental as Ferraris.

The Eiffel tower was almost torn down in 1909 its antenna saved it
The Eiffel tower was almost torn down in 1909, but was saved because of its antenna used both for military and other purposes, and the city let it stand after the permit expired. When the tower played an important role in capturing the infamous spy Mata Hari during World War I, it gained such importance to the French people that there was no more thought of demolishing it.- used for telegraphy at that time.

The Florida red-bellied turtle lies her eggs in an alligator nest for protection against nest predators
Closely related to the cooter is the Florida red-bellied turtle, Pseudemys nelsoni. Unless you can see one well enough to notice the patterning or coloration of the carapace, they can be difficult to distinguish from cooters. They are found in the same areas as cooters, but have a different, but also unique, nesting strategy. Females sneak into the territory of nesting alligators and bury their eggs in the mound of vegetation created by the mother alligator to protect and incubate her own eggs. In so doing, the turtles gain protection from nest predators due to the presence of the female alligator, and reap the benefits of the warmth generated by the decomposing vegetation of the gator nest.

No place in the pentagon is more than a seven-minute walk to an other spot
The Pentagon is the headquarters of the United States Department of Defense, located in Washington, D.C. It's one of the largest office buildings in the world, with an outside perimeter almost a mile long and containing 17.5 miles of corridors which are walked by some 26,000 employees and personnel. But it's also one of the most efficiently-designed -- any two points within the building are no more than a seven-minute walk apart.

The Alien Hand Syndrome is a disorder in which the hand of the sufferer seems to have a mind of its own
Alien hand syndrome (anarchic hand or Dr. Strangelove syndrome) is an unusual neurological disorder in which one of the sufferer's hands seems to take on a mind of its own. AHS is best documented in cases where a person has had the two hemispheres of their brain surgically separated, a procedure sometimes used to relieve the symptoms of extreme cases of epilepsy. It also occurs in some cases after other brain surgery, strokes, or infections.
An alien hand sufferer can feel normal sensation in the hand, but believes that the hand, while still being a part of their body, behaves in a manner that is totally distinct from the sufferer's normal behavior. They lose the 'sense of agency' associated with the purposeful movement of the limb while retaining a sense of 'ownership' of the limb. They feel that they have no control over the movements of the 'alien' hand, but that, instead, the hand has the capability of acting autonomously--i.e. independent of their voluntary control. The hand effectively has 'a will of its own.' Alien hands can perform complex acts such as undoing buttons, removing clothing, and manipulating tools. Alien behavior can be distinguished from reflexive behavior in that the former is flexibly purposive while the latter is obligatory. Sometimes the sufferer will not be aware of what the alien hand is doing until it is brought to his or her attention, or until the hand does something that draws their attention to its behavior

Gerald Ford was the only person to be vice president and president of US without being elected for it
Gerald Rudolph Ford, Jr. (born Leslie Lynch King, Jr.) (July 14, 1913 – December 26, 2006) was the 38th President of the United States, serving from 1974 to 1977, and the 40th Vice President of the United States serving from 1973 to 1974. He was the first person appointed to the vice-presidency under the terms of the 25th Amendment, and became President upon Richard Nixon's resignation at noon on August 9, 1974. Ford was the fifth U.S. President never to have been elected to that position, and the only one to have held both the office of Vice-President and the office of President while never having been elected to either. He was also the longest-lived president in U.S. history, dying at the age of 93 (when six weeks older than Ronald Reagan).

nectarine trees occasionaly produce peaches and vice versa
The nectarine is a cultivar group of peach that has a smooth, non-fuzzy skin. Though grocers treat fuzzy peaches and nectarines as different fruits, they belong to the same species. Nectarines have arisen many times from fuzzy peaches, often as bud sports.
Nectarines can be white, yellow, clingstone, or freestone. Regular peach trees occasionally produce a few nectarines, and vice versa. Their flesh is more easily bruised than peaches. The history of the nectarine is unclear; the first recorded mention is from 1616 in England, but they had probably been grown much earlier in central Asia.
