Myths of World "Friction Heat"

Imahe
Friction Heat The Myth:  Meteors are heated by friction when entering the atmosphere When a meteoroid enters the atmosphere of the earth (becoming a meteor), it is actually the speed compressing the air in front of the object that causes it to heat up. It is the pressure on the air that generates a heat intense enough to make the rock so hot that is glows brilliantly for our viewing pleasure (if we are lucky enough to be looking in the sky at the right time). We should also dispel the myth about meteors being hot when they hit the earth – becoming meteorites. Meteorites are almost always cold when they hit – and in fact they are often found covered in frost. This is because they are so cold from their journey through space that the entry heat is not sufficient to do more than burn off the outer layers.

Myths of World "Dark side of the Moon"

Imahe
Dark side of the Moon The Myth:  There is a dark side of the moon Actually – every part of the moon is illuminated at sometime by the sun. This misconception has come about because there is a side of the moon which is never visible to the earth. This is due to tidal locking; this is due to the fact that Earth’s gravitational pull on the moon is so immense that it can only show one face to us. Wikipedia puts it rather smartly thus: “Tidal locking occurs when the gravitational gradient makes one side of an astronomical body always face another; for example, one side of the Earth’s Moon always faces the Earth. A tidally locked body takes just as long to rotate around its own axis as it does to revolve around its partner. This synchronous rotation causes one hemisphere constantly to face the partner body.”

Myths of World "Brightest Star"

Imahe
8 Brightest Star The Myth:  Polaris is the brightest star in the northern hemisphere night sky Sirius is actually brighter with a magnitude of ?1.47 compared to Polaris’ 1.97 (the lower the number the brighter the star). The importance of Polaris is that its position in the sky marks North – and for that reason it is also called the “North Star”. Polaris is the brightest star in the constellation Ursa Minor and, interestingly, is only the  current  North Star as pole stars change over time because stars exhibit a slow continuous drift with respect to the Earth’s axis.

Myths of Worlds "Humans Pop In Space"

Imahe
Humans Pop In Space The Myth:  When exposed to the vacuum of space, the human body pops This myth is the result of science fiction movies which use it to add excitement or drama to the plot. In fact, a human can survive for 15 – 30 seconds in outer space as long as they breathe out before the exposure (this prevents the lungs from bursting and sending air into the bloodstream). After 15 or so seconds, the lack of oxygen causes unconsciousness which eventually leads to death by asphyxiation.

Myths of world "Evolutionary Improvements"

Imahe
Evolutionary Improvements The Myth:  Evolution causes something to go from “lower” to “higher” While it is a fact that natural selection weeds out unhealthy genes from the gene pool, there are many cases where an imperfect organism has survived. Some examples of this are fungi, sharks, crayfish, and mosses – these have all remained essentially the same over a great period of time. These organisms are all sufficiently adapted to their environment to survive without improvement. Other taxa have changed a lot, but not necessarily for the better. Some creatures have had their environments changed and their adaptations may not be as well suited to their new situation. Fitness is linked to their environment, not to progress.

The Stone in the Temple A Muslim Legend

Retold by Aaron Shepard Printed in Cricket, June 1995, and Australia’s School Magazine, Oct. 1995 “The sons of Makhzum should raise the Black Stone,” declared one of the men in the circle. “It is our right as foremost of the tribes.” “Who gave you such a position?” demanded another man. “The sons of Jumah will raise it!” “Not while the sons of Abdu Manaf stand here,” said another. “The honor should be ours.” “Then you will have to fight for it,” cried another. “None but the sons of Abdul-Dar shall raise the stone!” In the years before Muhammad’s holy mission, it happened that the tribes around Mecca decided to rebuild their temple, the Kaaba. In those days, the Kaaba was simply a yard enclosed by a wall. Their plan was to build a higher, thicker wall and add a roof. Each tribe had chosen a section of the wall and started pulling down the stones. The sacred Black Stone, built into the east corner, had been removed carefully and set aside. At last they had gotten down to the foundation l

Many were the merchants rich and proud in this great port city of Stavoren. But this woman, called by everyone “the Lady of Stavoren,” was richest and proudest of them all. “I said I want to hire you and your ship to bring me the most precious thing in the world.” “But what is the most precious thing?” asked the captain. “And where do I find it?” “If I knew,” said the Lady coldly, “I would already have obtained it. I ask you to discover and bring it to me. I will make sure you have ample gold to buy it, whatever it turns out to be.” “Forgive me, my Lady,” said the captain, “but I still don’t understand.” The Lady sat facing him. “Look around you, Captain. Have you seen a more magnificent mansion?” “Never, my Lady.” “I spared no exp

France – Broceliande Forest

According to legend, whenever the wizard Merlin could get away from affairs of state at the court of King Arthur, he would return to his lover, Viviane, in the forest of Brocéliande. In the forest, the fountain of Barenton is reputed to be the spot where Merlin first met Viviane, who was the daughter of the Lord of nearby Comper Castle. The castle’s lake is said to cover the palace that Merlin magically built for her. The fountain is also claimed to be the spot where Yvain, one of King Arthur’s Knights, defeated the Black Knight, the fountain’s guardian. One day, Viviane implored him to teach her his magical arts and gradually she learned all his magic. It is this knowledge that she used finally to imprison Merlin in nine invisible rings – a prison of air – to keep him from leaving her again to return to his duties at Arthur’s court. It is said that Merlin’s Tomb hides this prison of air.
