This mechanism was found inside a box at a wreck off the coast of the Greek island of Antikythera. After its discovery in 1902, scientists declared, after careful examination and restoration, that it had a gear inside it.
They say this mechanism, invented by early Greek scientists, can predict eclipses, and astronomical positions for decades in advance. This “analog computer” is said to date back to about 87 BC. It was discovered along with other artifacts such as statues, pottery, and jewelry, and it wasn’t noticed within two years of their possession.
The Cenote Angelita 'Underwater River'
Cenotes are more commonly known as sinkholes, and they are a result of a collapse of limestone bedrock that in turn exposes the water underground. These are common in islands and low-latitude areas such as coastlines. The Yucatan Peninsula in Mexico is popular for its “Ring of Cenotes,” in which Cenote Angelita is a part.
Diving inside the cenote called “Little Angel” means plunging into a cavern where the ancient Maya may have held sacrifices to their gods. The enclosed water is eerily calm and clear, cloaked with mystery. A bit farther down, at approximately a hundred feet, you will see an illusory floor that is actually a border between saline and freshwater.
This Dornier 17 Bomber
During the Second World War when bombing raids were regularly conducted, the main challenge had always been to outwit or outrun defending fighter aircraft. This prompted the Germans to invent the Dornier Do 17 “fast bomber” in the mid-1930s.
It was faster and also easier to maneuver. Because of its “shoulder wing” design, the aircraft was difficult to hit, and it was capable of running reconnaissance missions as well. This photograph shows a wreck of the aircraft hauled out from the Goodwin Sands in 2013 after it was discovered in 2008. It was reportedly shot down by enemy fire on August 28, 1940.
Antiquities from Makronisos
Because of its rich history and being one of the bedrocks of civilization, Greece has had a thriving world of archeology over the years. Because of the devastating economic crisis of recent times, Greece has been collaborating with archeological organizations from other countries to (literally) dive into their underwater treasure troves to explore their history in more detail, preserve precious artifacts, and use them as opportunities for more tourism.
Here, we can see a trove of antiquities that were discovered not too far from the island of Makronisos. This is just one of many of its kind and researchers are still finding more like it until this very day.
Underwater Statues, Cancun
Jason DeCaires Taylor wanted to combine his many skills and talents to produce a new art that was both useful and unique. He integrated his skills as a sculptor, photographer, marine conservationist, and licensed diving instructor, and he came up with works that are considered among the 25 wonders of the world.
The underwater statues in Cancun serve both as an art, which would, later on, develop into a coral reef. It has also become a popular tourist destination, like most of his other projects in the first public sculpture park in the Caribbean Sea.
