MOST FAMOUS SHIPWRECKS
USS Arizona
The USS Arizona was an American battleship built for the US Navy launched in 1915. The ship served many purposes, from escorting President Woodrow Wilson to the Paris Peace Conference to being sent to Turkey during the Greco-Turkish War, and was sent from California to Pearl Harbour, Hawaii in 1940 in response to the threat of Japanese Imperialism. On 7 December, 1941 USS Arizona was bombed by the Japanese, exploding and sinking. 1,177 crew members and officers were killed.
The shipwreck was declared a National Historic Landmark on 5 May 1989. Today the shipwreck remains and can be viewed at the USS Arizona Memorial, and is annually visited by two million people.

The Mary Rose
The Mary Rose was a Tudor warship commissioned and run during the reign of Henry VIII. Launched in 1511, it served in many battles against France, Brittany and Scotland, and in 1545 it sank during a battle against the French. Sinking in the Solent, close to the Isle of Wight, it was not rediscovered until 1971, and was salvaged in 1982. The remains of the shipwreck are now viewable in a museum in Portsmouth, and has become one of the most expensive and expansive projects in maritime archeology history.
In addition to the ship's structure itself, over 26,000 artefacts have been recovered - many of which are now on public display. The remains of about half of the deceased crew members have also been recovered, and bone analysis has revealed that many suffered from health conditions such as arthritis, rickets and scurvy.

Vasa
Vasa is a Swedish warship, believed to have been built between 1626 and 1628. The ship sank twenty minutes into its maiden voyage on 10 August 1628 after being hit by strong winds and flooding. Sinking less than a mile into its journey, it was regarded as a great embarassment for the King of Sweden, and there were several salvage attempts, but none were successful.
It was not until 1961 that the shipwreck was successfully recovered, including thousands of artifacts. The hull of the ship was found to be remarkably in tact and with the help of some restoration, the ship is now a popular Swedish tourist attraction, with over 22 million visitors to date.

The Queen Anne's Revenge
Queen Anne's Revenge was an 18th century warship mostly known for being the ship of legendary pirate Blackbeard (Edward Teach). First serving in the British Navy, the ship was later captured by the French and then by pirates from 1717 onwards. Although Blackbeard used the ship for less than a year, he achieved some of his greatest prizes during this time. In 1718 he grounded the ship and abandoned it, escaping capture by the British by boarding a smaller nearby ship.
In 1996 the remains of Queen Anne's Revenage were discovered, about one mile ashore from Atlantic Beach, North Carolina. So far thirty one canons have been discovered and more than a quarter of a million artifacts have been recovered. As one of the few pirate ships to be discovered, it is now listed on the US National Register of Historic Places.

MV Dona Paz
The sinking of the MV Dona Paz is remembered in history as the deadliest of all peacetime maritime distasters. It was a Philippine registered ferry and while carrying over 4,000 passengers, collided with an oil tanker MT Vector on December 20, 1987. A fire and explosion ensued, killing a predicted 4,386 passengers and there were only 24 survivors.
A lack of proper safety and communication measures were blamed, and it reportedly took 8 hours for the Philippine maritime authorities to hear of the incident. Due to the fire much fo the ship was destroyed, and it is now remembered as "Asia's Titanic."

The Black Swan
The Black Swan or The Black Swan Project, is believed to be the greatest recovery of gold treasure in history. The treasure was found on the remains of the Spanish warship Nuestra Senora de las Mercedes which sank off Portugal in 1804. In 2007 the American company Odyssey Marine Exploration announced that it had uncovered gold worth an estimated $500 million (£314 million).
However, the Spanish government declared that they rightfully owned the gold, and the case went all the way to the US Supreme Court, only for the gold to be returned to Spanish authorities in 2012, where it is now displayed in various exhibitions across the country.

MS World Discoverer
The MS World Discoverer was a Danish cruise ship created in 1974. While carrying passengers on a cruise in 2000 it struck a rock at the Solomon Islands, resulting in the ship subsiding. A distress signal was quickly dispatched and all crew and passengers were escorted safely to another passenger ferry.
There have been several attempts to salvage the shipwreck, but none have been successful, partly due to the fact that much of the ship has been looted and damaged during the Solomon Islands Civil War. The ship has remained at Roderick Bay ever since, and is now a popular local tourist attraction and it can even be viewed on Google Maps.

LITTLE WILLIE
Little Willie was the first working tank in the world. It proved that a vehicle encompassing armoured protection, an internal combustion engine, and tracks was a possibility for the battlefield.
In 1915 the First Lord of the Admiralty, Winston Churchill, created a Landships Committee to tackle the problems of trench warfare. After many experiments and false starts an agricultural firm, William Foster & Co. of Lincoln, was contracted to build a prototype machine.
Its designers, William Tritton and Walter Wilson came up with a set of workable tracks which were fitted to the ‘Landship’ now known as ‘Little Willie,’ said to be an irreverent nickname for the German Crown Prince, Kaiser Wilhelm.
By the time ‘Little Willie’ was built, Wilson and Tritton had already come up with an improved idea of a machine with tracks running all the way around the vehicle, which would be able to cross trenches. This would become the classic British tank design of the Great War.

Brief History of Internet
The Internet started in the 1960s as a way for government researchers to share information. Computers in the '60s were large and immobile and in order to make use of information stored in any one computer, one had to either travel to the site of the computer or have magnetic computer tapes sent through the conventional postal system.
Another catalyst in the formation of the Internet was the heating up of the Cold War. The Soviet Union's launch of the Sputnik satellite spurred the U.S. Defense Department to consider ways information could still be disseminated even after a nuclear attack. This eventually led to the formation of the ARPANET (Advanced Research Projects Agency Network), the network that ultimately evolved into what we now know as the Internet. ARPANET was a great success but membership was limited to certain academic and research organizations who had contracts with the Defense Department. In response to this, other networks were created to provide information sharing.

Bridge near Limyra
Year Built: Unknown – possibly c.3rd century CE
Location: Lycia, Turkey
Builder: Unknown
Still in Use: No
The Bridge near Limyra is a relatively unknown, yet unique stone bridge – it is believed to be one of the oldest segmented arch bridges in the world. The bridge is located near the ancient city of Limyra and is the largest civil engineering structure of antiquity in the region.
The way the arches of the bridge were built gives the bridge an unusually flat profile, which was unique in Roman engineering at the time. Due to this fact and the lack of comparable structures, it has been hard to date the construction of the bride, which is estimated to be sometime in the 3rd century. Additionally, very little scientific research has been conducted on the bridge and there is no information about the bridge from ancient sources.

Builder: Unknown
Still in Use: No
The Karamagara Bridge was built sometime in the 5th or 6th century during the era of the Byzantine Empire. The bridge consisted of a single pointed arch and is possibly the earliest known example of a pointed arch bridge.
Karamagara Bridge was part of larger Roman road that led to the city of Melitene in the Eastern Anatolia region of Turkey. The bridge is no longer usable today because it was submerged after the completion of the Keban Dam in 1975. Before this, Karamagara Bridge was examined by the Middle East Technical University of Ankara.

The World’s 10 Oldest Mountains – Formed Billions of Years Ago
The Earth is about 4.54 billion years old.
Through our history, mountain formations have been pillars of our planet’s long and storied past. These ancient peaks and ranges tell tales of continental shifts, geological events, and the relentless passage of time.
Let’s take a look at the world’s oldest mountain ranges.
1. Barberton Mountains, South Africa (3.5 Billion Years Old)
The Barberton Mountains, also known as Makhonjwa Mountains, are the oldest mountain range on Earth. These rocks are part of the Barberton Greenstone Belt in South Africa, which dates back approximately 3.5 billion years.
The landscape here is characterized by its greenstone composition, giving it a distinct, variegated appearance. It emerged from the intense volcanic activity and sedimentation on the Kaapvaal Craton, one of Earth’s oldest continental nuclei. This region is home to some of the best-preserved rocks.

Who Built the Ancient Roman Roads?
Roads were a key aspect of transportation in the Roman Empire. In addition to the streets built within Roman cities, the Roman military built several major highways, starting with the Appian Way, which was built during the Roman Republic in 312 BCE. The Appian Way was a paved road, named after Censor Appius Claudius Caecus, which connected the city of Rome to Capua and eventually Brindisi. The Roman military built several other highways including the Via Aurelia, Via Flaminia, and Via Aemelia. Roman highways were constructed by the military and connected the capital city of Rome to various other strategically important cities throughout the empire, including cities that had been invaded and colonized by the Roman military in Africa, Asia, and Europe. This is where the expression "all roads lead to Rome" comes from.
The primary purpose of the Roman system of highways was military transportation.

Carburetors were invented in 1888 by Karl Benz, one of the founders of Mercedes-Benz. It was a groundbreaking development for the industry at the time, and the technology was used by car manufacturers up until the late 1980s, when carburetors began getting replaced by fuel injection systems.
Egyptian (5000 years old)
Egypt is considered to be one of the oldest civilizations in the world, and Egyptian Coptic is the oldest indigenous language of Egypt. Written records of its usage date back to 3400 BC, making it an ancient language. Coptic was the most widely spoken language in Egypt till the late 17th century AD until it was replaced by Egyptian Arabic, post-Muslim invasion. Coptic is still used as the liturgical language at the Coptic Church in Egypt. Only a handful of people fluently speak the language today.

Sanskrit (5000 years old) - World's Oldest Language
Unlike Tamil, which is still a widely spoken language, Sanskrit is the oldest language in the world but fell out of common usage around 600 B.C. It is now a liturgical language - the holy languages found in the scriptures of Hinduism, Buddhism and Jainism. The first written record of Sanskrit can be found in Rigveda, a collection of Vedic Sanskrit hymns, which was written in somewhere around 2nd millennium B.C. According to studies, Sanskrit forms the base for many European languages and is still one of India's official languages.

World's oldest cave art found showing humans and pig
The oldest example of figurative cave art has been discovered in the Indonesian Island of Sulawesi by Australian and Indonesian scientists.
The painting of a wild pig and three human-like figures is at least 51,200 years old, more than 5,000 years older than the previous oldest cave art.
The discovery pushes back the time that modern humans first showed the capacity for creative thought.
Prof Maxime Aubert from Griffith University in Australia told BBC News that the discovery would change ideas about human evolution.

Beginning as early as 600 B.C., the ancient Greeks created the Diolkos, an ambitious road partially paved with stone, that spanned across the entire Isthmus of Corinth. The overland route allowed sailors to avoid the perilous circumnavigation of the Peloponnese peninsula.
The history of Greece can be traced back to Stone Age hunters. Later came early farmers and the Minoan and Mycenaean civilizations. This was followed by a period of wars and invasions, known as the Middle Ages. Around 1100 BC, the people of the Dorians invaded from the north and spread along the west coast. In the period 500-336 BC, Greece was divided into small city-states, each of which consisted of a city with the surrounding countryside.
The ancient Greek classical and Hellenistic eras are without doubt the most beautiful times, having left behind a myriad of ideas, concepts and the basics of what we now call "Western civilization". However, the previous two millennia leading to these ancient times, as well as the following two millennia, are all part of the history of Greece after leaving an equally rich cultural imprint on the territory. Much of the Greek civilization has survived either directly or through changes to the present day.

Hadrian’s Wall, England/Scotland
Hadrian’s Wall is well known to most casual students of history.
The Roman Emperor Hadrian in 122 AD ordered for the construction of the wall along with 16 fortresses garrisoned with static troops. The length of the wall expanded from the Irish Sea to the banks of the River Tyne near the North Sea — a distance of 73 miles.
The purpose of the wall is obvious, but as to why it was constructed, remains disputed. The reason for this is that there is no clear evidence that suggests Roman Britain, south of the future wall, was under any real substantial threats — even though there had been some minor rebellions in the province and within the Roman Empire. This was probably the reason why Hadrian built the wall — as a symbol and reminder that it is best to separate one from the barbarians.
Hadrian’s Wall would provide Roman Britain security from the Celtic/Pictish tribes in the north until Rome abandoned Britannia in 410 AD.

Great Wall of Gorgan, Parthian/Sassanid Empire
The Great Wall of Gorgan is a fortress that remains mostly unknown. Located in northeastern Iran, the wall stretches from the Caspian Sea to the Kopet Dag Mountain Range. In total, the wall was 121 miles long.
The date of its construction is disputed. Some say it is 1,000 years older than the Great Wall of China. While little is known about the wall, the Parthians (247 BCE – 224 AD) who ruled Iran, are said to have built on the original remains of the wall.
The original height and width is unknown, but when the Sassanid Empire (224–651) overthrew the Parthians they repaired, enlarged, and added fortresses to the wall. The height of the Gorgan wall has yet to be determined. The width of the wall was between 20 to 30 feet wide and featured 30 fortresses.
What made this wall significant was that for many centuries it prevented nomads from the north, like the Dahae, Massagetae, Hephthalites and other various nomadic elements from getting in.

The World’s Strongest Fortifications Ever
Masada, Israel
On a rocky plateau situated on a hill in southern Israel near the edge of the Judean desert, one can find the fortress of Masada. Almost all information on Masada and the siege that took place comes from the first-century Jewish Roman historian Josephus.
The fortress of Masada withstood a year-long siege by Roman Gov. Lucius Flavius Silva. (Photo from Wikimedia Commons)
In 66 AD, the Kingdom of Judea was in upheaval over Rome’s prolonged occupation and revolted. In doing so, a small group of rebels known as the Sicarii captured Masada after slaughtering its Roman garrison. In 72 AD, Lucius Flavius Silva, commander of the Legio X Fretensis, laid siege to Masada.
To reach the top, Lucius gave the order to build a massive ramp that was 375 feet high and 450 feet long. Once the legionaries made it to the top, they rolled the siege engines in and battered Masada’s walls until they fell.

Modern and early cameras are devices capable of capturing still or moving images with light. They use light through optics, mechanics, electronics, and chemistry. Modern digital devices use an electronic sensor, while analog mediums use film.
In the 19th century, large-format cameras, such as the daguerreotype, were used. They used cumbersome equipment and complex processes.
The 20th century saw the birth of more portable and convenient devices, such as the iconic Leica 35mm.

It is difficult to say who owned the first invention of the camera. Its creation is attributed to several people of different eras. For example, it is known that the oldest camera obscura was developed by scientist Ibn al-Haytham in the 11th century.
The history of the camera is shaped by the contributions of numerous inventors and pioneers who left an indelible mark on the evolution of photography. Among them, Joseph Nicephore Niépce is one of the first figures credited with creating the world's first photograph in 1826 using a camera obscura and a light-sensitive chemical mixture. The already mentioned Louis Daguerre revolutionized the way images were taken. George Eastman introduced the improved Kodak camera in 1888. Edwin Land created the Polaroid instant camera in 1948. They laid the foundations of photographic technologies and paved the way for the next generation of inventors of modern photo devices.

When Was the Telephone Invented?
Alexander Graham Bell, best known for his invention of the telephone, revolutionized communication as we know it. His interest in sound technology was deep-rooted and personal, as both his wife and mother were deaf. While there’s some controversy over whether Bell was the true pioneer of the telephone, he secured exclusive rights to the technology and launched the Bell Telephone Company in 1877. Ultimately, the talented scientist held more than 18 patents for his inventions and work in communications.

Damascus, Syria
One of the oldest cities in the Middle East, Damascus was founded in the 3rd millennium B.C., and through excavation sites, archeologists have been able to prove that the area was first inhabited sometime between 8,000 and 10,000 B.C. Located in present-day Syria, the city is a unique place as so many cultures have made it what it is today, including elements of Roman and Greek city urban planning. Islam has also had a great influence, which is evident in the Umayyad Mosque. Also known as the Great Mosque, it is one of the largest and oldest mosques in the world, built sometime between A.D. 705 and 715.

The first confirmed building of a submarine comes from 1620, with a submersible designed and built by Cornelis Drebbel, a Dutchman in the service of King James I of England. His device used oars to steer, and between 1630 and 1624, two improved versions were tested in the River Thames.
The $2 Billion Migaloo M5 Is World's First Luxury Super Submarine, Loaded With Amenities
This is Migaloo M5, the world's first luxury super submarine and the one vessel that could withstand any storm – at least in theory. It's a super submarine because it's technically a superyacht megayacht in submarine disguise, loaded with amenities and features even today's most outrageous megayachts lack.
It's priced to match, too: the M5 starts at $2 billion before the owner can add whatever features he or she thinks could turn this vessel into an off-grid home, either for leisure cruising or as the go-to solution for that dreaded scenario when the world goes bust.

In 1813, about 400 years after Fontana built his wheeled contraption, a German aristocrat and inventor named Karl von Drais began work on his own version of a Laufmaschine (running machine), a four-wheeled, human-powered vehicle. Then in 1817, Drais debuted a two-wheeled vehicle, known by many names throughout Europe, including Draisienne, dandy horse and hobby horse, IBF says.
The first known iterations of a wheeled, human-powered vehicle were created long before the bicycle became a practical form of transportation. In 1418, an Italian engineer, Giovanni Fontana (or de la Fontana), constructed a human-powered device consisting of four wheels and a loop of rope connected by gears, according to the International Bicycle Fund (IBF).
Who invented the bicycle?
You might think that an invention as simple as the bicycle would have an uncomplicated past. But as it turns out, this highly popular invention has a history fraught with controversy and misinformation. While stories about who invented the bicycle often contradict one another, there's one thing that's certain: the very first bicycles were nothing like the ones you see cruising down the street today.

The piano was invented by Bartolomeo Cristofori (1655-1731) of Italy.
Cristofori was unsatisfied by the lack of control that musicians had over the volume level of the harpsichord. He is credited for switching out the plucking mechanism with a hammer to create the modern piano in around the year 1700.

The first boats
No one knows exactly when the first boat was invented. Long ago, people probably discovered that they could keep themselves afloat by clinging onto fallen logs or bundles of reed. Gradually, they learnt how to hollow out logs to make rafts.

Between 1200 and 900 BC, the Greeks and the Phoenicians began to build up their sea trade. They used galleys, both as merchant ships for trading, and as warships. Rowers powered the fighting galleys, sitting in one, two or three lines. The Phoenicians made many long sea journeys, but stayed quite close to the coast.
The oldest pictures of boats that have ever been found are Egyptian, on vases and in graves. These pictures, at least 6000 years old, show long, narrow boats. They were mostly made of papyrus reeds and rowed using paddles. The Egyptians used their ships to trade with other countries around the Mediterranean sea.

Gottlieb Daimler in 1896
Pragmatism was behind the design of the first truck in the world, which looked like a cart with an engine and without a drawbar. The engine, called "Phoenix", was a four-horsepower-strong two-cylinder engine located at the rear, with a displacement of 1.06 litres, originating from a car.

The first truck in the world in 1896
One of the greatest talents of inventor Gottlieb Daimler was finding new areas of application for his engine. He invented the motor cycle, then went to the motorised trolley car, a motorised firefighting hose and then, almost inevitably, to the truck in the year 1896.
