Incredible Shipwrecks Around The World  

Sunken ships have long held a special allure for young children, treasure hunters and archaeologists alike. UNESCO estimates there are three million shipwrecks lost in the oceans, with just a fraction having been discovered by explorers. Click through the slideshow to view the most impressive shipwrecks ever captured on film.

SS President Coolidge Hull

SS President Coolidge Hull

 At the time of its christening in 1931, the SS President Coolidge was the largest and finest vessel built by an American shipyard. Prior to World War II, the ship was operated by the American President Lines as a luxury liner providing trans-Pacific passage and commercial service. Shortly after the attack on Pearl Harbor, the ship was converted for military use and could carry more than 5,000 troops.

SS President Coolidge

SS President Coolidge

 The SS President Coolidge hit underwater mines and sank off the coast of Vanuatu in the Pacific Ocean. All but two passengers survived the ordeal. Guns, cannons, Jeeps, chandeliers and a mosaic tile fountain can be found among the wreckage.



 Today the remains of the two-masted Sweepstakes can be found in Ontario’s Big Tub Harbor. The shallow depth of 20 feet and clear water make the vessel easily visible from the shore or aboard a boat. There are 22 shipwrecks throughout Fathom Five National Marine Park, where the Sweepstakes is located.



 The coal-toting schooner was damaged off Cove Island in August 1885 and was later towed to the head of Big Tub Harbour, located in the Fathom Five National Marine Park. The Sweepstakes was not repaired in time, causing it to sink in September 1885.



Titanic, possibly the most talked-about shipwreck tragedy in history, set out from Southampton to New York on April 10, 1912 on its maiden voyage. Built at the Harland and Wolff shipyard in Belfast, the White Star Line steamer was renowned for its opulence, luxury, and presumed safety.

Titanic Railing

Titanic Railing

 The renowned ship sank in the early hours of April 15, 1912, a little more than four days after it set sail, when it collided with an iceberg in the Atlantic Ocean. “The ship was believed to be unsinkable at the time she was lost and is considered to be one of the deadliest peacetime maritime disasters in history,” Stemm said. More than 1,500 people lost their lives.

Sea Tiger

Sea Tiger

 Originally a Chinese-owned vessel used to transport illegal immigrants, the Sea Tiger was confiscated in 1992 by the United States Coast Guard. The boat was later auctioned off to Voyager Submarines for a $1. Voyager spent more than $250,000 acquiring environmental and logistical approval from multiple government agencies in order to sink the ship for tourist use.



 Shipwrecked near the Croatian coast, Lina is one of the most well-preserved wrecks in the Adriatic. The steel merchant ship was used to transport timber from Rijeka to Sicily before it struck an underwater reef and sank in January 1914. The entire crew was saved. Today, Scuba divers can view cabins, two masts, upper deck and holes in the lower part of the boat where the hull struck the reef.

Oseberg Ship

Oseberg Ship

The Oseberg Burial Ship, a ninth-century royal burial ship, excavated on the Oslo Fjord in Norway in 1904, was largely intact because it had been buried in blue clay, a substance known for its preserving qualities. The burial chamber, which held the bodies of two women, was further sealed beneath a mound of sod, wrote Nigel Pickford, in “The Atlas of Shipwrecks & Treasure.” He said the find is important because the ship reflects Viking shipbuilding methods and styles from the early 800’s and is also “a unique work of art, with its elaborately carved stern and stern posts depicting an intricate maze of mythological beasts.”

SS Republic

SS Republic

 During a violent hurricane on October 25, 1865, the SS Republic a Civil War-era side-wheel steamship, got lost and sank on its way to New Orleans from New York. The passengers and crew escaped but a fortune in precious cargo–including a stunning variety of everyday wares essential to life in mid-19th century America–sank to the bottom of the Atlantic seabed. It was discovered in 2003 by Odyssey Marine Exploration, nearly 140 years later, approximately 100 miles off the Georgia Coast. The company recovered more than 51,000 American gold and silver coins and some 14,000 other artifacts from the wreck site.



In 1915, while the Lusitania sailed from New York to Liverpool, the ship was hit by a German torpedo and quickly sank off the coast of Ireland. The passenger ship was part of the Cunard line. About 1200 men, women and children perished, including more than one hundred Americans. The incident is thought to be instrumental in bringing the United States into World War I.



The Whydah, a pirate ship belonging to the English pirate “Black Sam” Bellamy, was lost on a stormy night in 1717 off the coast of Cape Cod. In 1984, a team led by underwater explorer Barry Clifford located the wreck. Many of the estimated 200,000 artifacts–including gold doubloons and silver pieces of eight–can be seen at The Whydah Museum in Provincetown, Mass., or at the “Real Pirates” traveling exhibit. Recovery work at the site continues.

Antikythera Ship

Antikythera Ship

 The Antikythera Ship, a Roman merchant ship was discovered in 1900 by sponge divers off the coast of Antikythera, a tiny Greek Island between Crete and mainland Greece. Salvage work, which was difficult and dangerous, yielded “Statue of a Youth,” a well preserved bronze sculpture submerged for nearly 2,000 years, and “Philosopher’s Head.” Though no photos of the shipwreck exist, objects such as this piece of a scientific mechanism have been salvaged for archaeological study.

Our wonderful planet Earth

  •  We all know that earth is a sphere, three-fourths of it is covered with water; it is the only planet in the universe which is known to have life. We have grown up reading these facts in our schools and they are no longer interesting for us. But there are a number of other amazing realities about our planet that we do not know.
  • What are they? Have a look.
  • Rocks on earth can grow and float.
  • Moon was much closer to earth a billion years ago.
  • It took 20 days to make a month and days were just 18 hours long.
  • Moon is moving away from Earth at the rate of 1.6 inches a year.
  • Earth is gradually slowing down. Every few years, an extra second is added to make up for lost time.
  • Earth’s inside is fluid and is moving the same way as tornados and hurricanes.
  • Our planet is more than 4.5 billion years old, just a shade younger than the Sun.
  • On an average over a hundred lightening strikes occur worldwide every second.
  • The Antarctic Ice Sheet holds nearly 90 percent of the world’s ice and 70 percent of its fresh water. If the entire ice sheet were to melt, sea level would rise by nearly 220 feet, or the height of a 20-story building.
  • Mt. Cotopaxi in Ecuador supports the only glacier on the equator.
  • The creosote bush, which grows in the Mojave, Sonoran, and Chihuahuan deserts, has been shown by radiocarbon dating to have lived since the birth of Christ.
  • About 400 billion gallons of water is used worldwide everyday.
  • Earth is the only planet in the Solar System not to be named after a mythical God.
  • From a distance in space, Earth seems to be the brightest of the 8 planets. This is because large amount of sunlight is reflected by the water on the planet.
  • Earth is the densest planet in the Solar System.
  • El Azizia (Libya) is the hottest place on Earth, while Vostok (Antarctica) is the coldest.
  • The Atlantic Ocean is the saltiest of Earth’s major oceans.
  • Hawaii is moving towards Japan at the speed of 10 cm a year.
  • The Persian Gulf is the warmest sea. In the summer its temperature reaches 35.6 degrees centigrade.
  • Louisiana loses about 30 square miles (78 square kilometers) of land each year to coastal erosion, hurricanes, other natural and human causes and a thing called subsidence, which means sinking.
  • The world’s deadliest recorded earthquake occurred in 1557 in central China. More than 830,000 people were killed.
  • About 540 volcanoes on land are known to have erupted in the past. 20-30 volcanoes erupt yearly, but mostly from under the sea.
  • Sunlight can penetrate clean ocean water to a depth of 240 feet.
  • Antarctica is the highest, driest, and coldest continent on Earth.
  • The blue whale, Balaenoptera musculus, is the largest known animal ever to have lived on sea or land.
  • The Peregrine Falcon around 200mph (320 km/h) is the fastest bird on the planet.
  • Water-meal or Wolffia globosa is the smallest flower in the world, it contains some 38 species of the smallest and simplest flowering plants.
  • The largest eggs in the world are laid by a shark.
  • A huge underground river runs underneath the Nile, with six times more water than the river above.
  • 80% of all life lives under the under the ocean’s surface.
  • 2 million pounds of space dust reaches Earth’s surface each year. Scientists think that this dust carries space microbes that give us flu.
  • Astronomers know that over the next few billion years, the Sun will swell to such an extent that it will envelop Earth.
  • So global warming is to occur anyways!

The Amazon Rainforest, also known as Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon Basin of South America.

More than half of the forest is contained within Brazil, the rest of it in Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana, covering five and a half million square kilometers, or 1.4 billion acres.

The Amazon represents over half of the planet’s remaining rainforests, and it comprises the largest and most species-rich tract of tropical rainforest in the world. The diversity of plant species is the highest on Earth. One in ten known species in the world lives in the Amazon Rainforest.

If we want to save our planet, we have to preserve the rainforest
































































10 Most Famous Diamonds in the World

The most famous diamonds in the world are not only beautiful and very expensive, but also full of both history and mystery. There are many such diamonds in the world. Their different colors, sizes and stories make them all interesting and unique.  Here is  the 10 most famous diamonds in the world.

1. The Hope Diamond

hope diamond

The Hope Diamond is not only one of the most famous gems in the world, but it is also one of the largest blue diamonds (4th largest). It’s physical value might be estimated but it’s historical importance is priceless. It is so old that no one knows exactly when it was discovered. However, it already had an owner in 1668, in the person of an Indian slave who claimed that the 112 carats stone (which he believed to be a sapphire) came from the eye of an idol. Jean Baptiste Tavernier, a traveler and a gem merchant bought it and sold it afterwards to King Louis XIV of France. Its price today is estimated at $250 million. The legend says that this diamond was cursed by the Hindu priests of the temple from where it was stolen.

2. The Golden Jubilee

golden jubilee diamond

The Golden Jubilee is holding the title of the world’s largest faceted diamond in the world, measuring 545,67 carats. It was discovered in 1985, in the Premier mine of South Africa. At first, it was considered an ugly brown diamond. Gabriel Tolkowsky received the diamond, which was supposed to be used at testing some new tools and cutting methods. The result astonished everyone. It turned out that the “Unnamed Brown” was actually a very beautiful yellow-brown diamond. It remained unnamed until it was presented to the king of Thailand in 1997, for the 50th anniversary of his coronation (thus, its name).

3. The Cullinan I

cullinan diamond

One of the most famous diamonds in the world, Cullingam I was justly considered the largest diamond in the world up to the discovery of the Golden Jubilee. Also known as “The star of Africa”, the pear-shaped stone is the largest of the 9 diamonds cut from the largest rough diamond ever, the Cullinan diamond(3106,75 carats). Currently, it is the head of St. Edward’s scepter, one of the British Crown Jewels but it can be removed and worn as a brooch.

4. The Idol’s Eye

idol's eye

The idol’s eye is one of the most mysterious diamonds in the world. Its entire history is unknown; we have no idea where it came from, when it was discovered or who owned it. The only clue is its name, “The Idol’s Eye”. It appeared in a note, at Christie’s when it was described as a flawless large diamond. It was bought by an anonymous buyer and disappeared again for some years. Its owners changed several times afterwards and was bought in 1979 by Mr. Laurence Graff, who sold it again in 1983, to an anonymous buyer who is believed to own the diamond today.

5. The Spirit of de Grisogono

spirit de grisogono

This is one of the famous diamonds in the world. It is also known as the largest cut black diamond, and it measures 312, 24carats. This beautiful diamond was named after the Swiss jeweler who cut it, using the old Mogul style. The result was the jewel you see in the picture and it is the work of an entire year. Currently, it is owned by a private client, who must be a very fortunate person.

6. Koh-I-Noor /Mountain of light

koh i noor

Apparently, this is one of the oldest diamonds known to man. According to the legend, this diamond is more than 2000 years old, from before the birth of Christ. However, a much more documented hypothesis is that it was discovered in the early 1300s. The earliest recorded mention of the diamond is in the memories of Babur (Baburnama), the first Mogul ruler of India. It then passed through many hands and its long, complex history cannot be told here. It suffices to say that the diamond arrived to England in the 19th century and entered the possession of Queen Victoria. Not satisfied with its cutting, which caused it to shine less than it should have, the queen had it recut, which meant a loss of weight of almost 43%. It was then set in the queen’s crown,in frontal position. India did not give up one of its most precious gems easily. The Indian government continued to ask the return of the diamond, with no success.

7. The Orlov


The Orlov is one of the most intriguing diamonds in the world. It has a blurry past and it is said that it was stolen from an idol, where the stone stood as one of the eyes of the statue. However, many questions remain: First, if this is true, what happened to the other eye? Could it have been the above mentioned Koh-i-Noor? Another theory is that the Orlov diamond is actually the legendary stone called the Great Mogul, which was only described by Jean Baptiste Tavernier and it was lost forever centuries ago. Whatever the truth, The Orlov diamond is now in the possession of the Russian government and it is set in the Imperial scepter. It is estimated at 189 carats but its historical value cannot be priced.

8. The Florentine


The Florentine is an enigmatic diamond which is believed to have a light yellow color, with a green overtone and an estimated 137 carats. Its known history starts with the duke of Burgundy in the 15th century. Apparently, he died in battle while wearing the diamond. The stone was stolen from him by a peasant who sold it for a florin, because he thought it was mere glass. It then changed owners several times, for small amounts of money. In the 17th century, we find the Florentine in the possession of the Medici familly. When the last Medici died, the diamond arrived in Vienna, and became one of the Habsburg Crown Jewels. After the World War I, it was stolen and never found again, though a particular diamond was believed to be the lost one, because of its similarities with the Florentine.

Why does water not calm the tongue after eating hot spicy food?
The spices in most of the hot foods that we eat are oily, and, like your elementary school science teacher taught you, oil and water don’t mix. In this case, the water just rolls over the oily spices.

What can you do to calm your aching tongue? Eat bread. The bread will absorb the oily spices. A second solution is to drink milk. Milk contains a substance called “casein” which will bind to the spices and carry them away. Alcohol also dissolves oily spices.

Why does wet fabric appear darker?

When fabric gets wet, light coming towards it refracts within the water, dispersing the light. In addition, the surface of the water causes incoherent light scattering. The combination of these two effects causes less light to reflect to your eyes and makes the wet fabric appear darker.

Why is blue for boys and pink for girls?
In ancient times, it was believed that certain colors could combat the evil spirits that lingered over nurseries. Because blue was associated with the heavenly spirits, boys were clothed in that color, boys then being considered the most valuable resource to parents. Although baby girls did not have a color associated with them, they were mostly clothed in black. It was only in the Middle Ages when pink became associated with baby girls.

Why do people kiss under the mistletoe at Christmas?
In ancient myth, when the son of the Norse goddess Frigga, Baldr, was killed by an arrow made of mistletoe and then brought back to life, she blessed the mistletoe and bestowed a kiss on all who passed beneath it. In the 18th century, the legend was adopted as a promise to marry. At Christmas a lady standing under a mistletoe may not refuse a kiss. If she does, she cannot expect to marry the following year. So it is told.

Why are there bunnies and eggs at Easter?
The ancient Anglo-Saxons celebrated the return of spring with a carnival commemorating their goddess of offspring and of springtime, Eostre. The word carnival possibly originated from the Latin ‘carne vale’ meaning “flesh, farewell” or “meat, farewell.” The offerings were rabbits and colored eggs, bidding an end to winter.
As it happened, the pagan festival of Eostre occurred at the same time of year as the Christian observance of the Resurrection of Christ and it didn’t take the Christian missionaries long to convert the Anglo-Saxons when they encountered them in the second century. The offering of rabbits and eggs eventually became the Easter bunny and Easter eggs.

If blood is red, why are veins blue?
Blood is bright red in its oxygenated form and a dark red in deoxygenated form. In simpler terms, it is bright red when it leaves the lungs full of oxygen and dark red when it returns to the lungs for a refill. Veins appear blue because light penetrating the skin is absorbed and reflected in high energy wavelengths back to the eye. Higher energy wavelengths are blue.

Why did Columbus and others try to sail around the world?
You probably know that people native to the Americas are called “Indians” because early explorers like Christopher Columbus thought they had come across the Indian spice islands. Traders were forced to sail westward after the spice route to the East by land was blocked for Europeans by Muslim uprisings.

Why is it called a “loo?”
The British word for toilet, “loo”, derives from the French “garde a l’eau!” In medieval Europe people had little conception of hygiene and threw the contents of their chamber pots out the window into the street below. In France the practice was preceded by “garde a l’eau!” (“watch out for the water!”). In England, this phrase was Anglicized, first to “gardy-loo!”, then just “loo”, and eventually came to mean the toilet/lavatory itself. The American word for toilet, “john”, is called after the John Harington who in 1596 invented an indoor water closet for Queen Elizabeth I.

Why is the sky blue?
When sunlight travels through the atmosphere, it collides with gas molecules. These molecules scatter the light. The shorter the wavelength of light, the more it is scattered by the atmosphere. Because it has a shorter wavelength than the other colors, blue light is scattered more, ten times more than red light, for instance. That is why the sky is blue.
Why does the setting sun look reddish orange? When the sun is on the horizon, its light takes a longer path through the atmosphere to reach your eyes than when the sun is directly overhead. By the time the light of the setting sun reaches your eyes, most of the blue light has been scattered out. The light you finally see is reddish orange, the color of white light minus blue.

Why do onions make you cry?
Onions, like other plants, are made of cells. The cells are divided into two sections separated by a membrane. One side of the membrane contains an enzyme which helps chemical processes occur in your body. The other side of the membrane contains molecules that contain sulfur. When you cut an onion, the contents on each side of the membrane mix and cause a chemical reaction. This reaction produces molecules such as ethylsufine which make your eyes water.
To prevent crying when you cut an onion, cut it under a running tap of cold water. The sulfur compounds dissolve in water and are rinsed down the sink before they reach your eyes. You can also put the onion in the freezer for ten minutes before you cut it. Cold temperatures slow down the reaction between the enzyme and the sulfur compounds so fewer of the burning molecules will reach your eyes.

Why do you get hiccups?
Hiccups happen when the diaphragm, the muscle that controls our breathing, becomes irritated and start to spasm and contract uncontrollably. With each contraction, air is pulled into the lungs very quickly, passes through the voice box, and then the epiglottis closes behind the rush of air, shaking the vocal chords, causing the “hic” sound. The irritation can be caused by rapid eating, emotional stress and even some diseases. The best cure? Breathing into a paper bag. This calms the diaphragm by increasing the amount of carbon dioxide in your bloodstream.

Why are camels called “ships of the desert?”
Camels are called “ships of the desert” because of the way they move, not because of their transport capabilities. Camels sway from side to side because they move both legs on one side at the same time, elevating that side. This is called pacing, a ship-like motion which can make the rider feel sick.
