History of Robots and Planes
The history of robots has
its roots as far back as ancient myths and legends. Modern concepts were begun
to be developed when the Industrial Revolution allowed the use of more complex
mechanics and the subsequent introduction of electricity made it possible to
power machines with small compact motors. After the 1920s the modern
formulation of a humanoid machine was developed to the stage where it was
possible to envisage human sized robots with the capacity for near human
thoughts and movements, first envisaged millennia before.
The first uses of modern robots were in factories as
industrial robots – simple fixed machines capable of manufacturing tasks which
allowed production without the need for human assistance. Digitally
controlled industrial robots and robots
making use of artificial intelligence have been
built since the 1960s. Chinese accounts relate a history of automata back to
the 10th century BC when Yan Shi is credited with making an automaton
resembling a human in an account from the Lie Zi text.
Western and Eastern civilisations have concepts of
artificial servants and companions with a long history. Many ancient
mythologies include artificial people, such as the mechanical servants built by
the Greek god Hephaestus (Vulcan to the Romans), the clay golems of
Jewish legend and clay giants of Norse legend.
Likely fictional, the Iliad illustrates
the concept of robotics by stating that the god Hephaestus made talking mechanical handmaidens out of
gold. Greek mathematician Archytas of Tarentum is reputed to have built a
mechanical pigeon around 400 BC, possibly powered by steam, capable of flying.
The clepsydra was made in 250 BC by Ctesibius of Alexandria, a physicist and
inventor from Ptolemaic Egypt. Heron of Alexandria (10–70 AD) created some
mechanical devices in the late 1st century AD, including one that allegedly
could speak. Aristotle took up an earlier reference
in Homer's Iliad and speculated that automatons could someday
bring about human equality by making the abolition of slavery possible in his
book Politics (ca. 322 BC).
In ancient China, a curious account on automata is found
in the Lie Zi text, written in the 3rd century BC. Within it there is
a description of a much earlier encounter between King
Mu of Zhou (1023–957 BC) and a mechanical engineer known as Yan Shi,
an 'artificer'. The latter proudly presented the king with a life-size,
human-shaped figure of his mechanical handiwork.
The king stared at the figure in astonishment. It walked
with rapid strides, moving its head up and down, so that anyone would have
taken it for a live human being. The artificer touched its chin, and it began
singing, perfectly in tune. He touched its hand, and it began posturing,
keeping perfect time...As the performance was drawing to an end, the robot
winked its eye and made advances to the ladies in attendance, whereupon the
king became incensed and would have had Yen Shih [Yan Shi] executed on the spot
had not the latter, in mortal fear, instantly taken the robot to pieces to let
him see what it really was. And, indeed, it turned out to be only a
construction of leather, wood, glue and lacquer, variously coloured white,
black, red and blue. Examining it closely, the king found all the internal
organs complete—liver, gall, heart, lungs, spleen, kidneys, stomach and
intestines; and over these again, muscles, bones and limbs with their joints,
skin, teeth and hair, all of them artificial...The king tried the effect of
taking away the heart, and found that the mouth could no longer speak; he took
away the liver and the eyes could no longer see; he took away the kidneys and
the legs lost their power of locomotion. The king was delighted.
Early water clocks are sometimes grouped in with the
beginning of robotics. They began in China in the 6th century BC and the
Greco-Roman world in the 4th century BC where the Clepsydra is known to have been
used as a stop-watch for imposing a time limit on clients' visits in Athenian brothels.
The idea of artificial people in western mythology dates at least as far back as the ancient legends of Cadmus, who sowed dragon teeth that turned into soldiers, and the myth of Pygmalion, whose statue of Galatea came to life. In Greek mythology, the deformed god of metalwork (Vulcan or Hephaestus) created mechanical servants, ranging from intelligent, golden handmaidens to more utilitarian three-legged tables that could move about under their own power, and the bronze man Talos defended Crete.
Concepts akin to a robot can be found as long ago as the 4th
century BC, when the Greek mathematician Archytas of
Tarentum postulated a mechanical bird he called "The Pigeon" which
was propelled by steam.
Yet another early automaton was the clepsydra,
made in 250 BC by Ctesibius of Alexandria,
a physicist and inventor from Ptolemaic
Egypt. Hero of Alexandria (10–70 AD) made
numerous innovations in the field of automata, including one that allegedly
could speak.
Taking up the earlier reference in Homer's Iliad, Aristotle speculated
in his Politics (ca. 322 BC, book 1, part 4) that automatons could someday
bring about human equality by making possible the abolition of slavery:
– There is only one condition in which we can imagine
managers not needing subordinates, and masters not needing slaves. This
condition would be that each instrument could do its own work, at the word of
command or by intelligent anticipation, like the statues of Daedalus or the
tripods made by Hephaestus, of which Homer relates that "Of their own
motion they entered the conclave of Gods on Olympus", as if a shuttle
should weave of itself, and a plectrum should do its own harp playing.
Jewish lore mentions the Jewish legend of the Golem, a clay
creature animated by Kabbalistic magic. Similarly, in the Younger
Edda, Norse mythology tells of a clay giant,
Mokkurkalfi or Mistcalf, constructed to aid the troll Hrungnir in a duel
with Thor, the
God of Thunder.
Egyptian airplane
Estimated to be from a period 500 – 800 BC and found in
Pre-Inca archeological sights, gold figurines have been found. These figurines
seem to resemble airplanes.
In 1997 researchers built models of some of these figurines.
Using exact scales and only adding an engine and propeller, these researchers
built remote controlled planes. These models could not only take off and land
but could also do aerobatic maneuvers such as: turns, rolls and loops.
In a tomb in Saqquara, Egypt and dating back to about 200BC,
a wooden object was found. This object was about 7 inches in length and had
what now appears to be swept down wings and a tail.
This object was found in 1898 and as planes did not come
into existence until 1903, it was catalogued
and stored as a bird. Source : Wikipedia
Baalbeck is a city in eastern Lebanon famous chiefly for its magnificent, excellently preserved Roman temple ruins. It was a flourishing Phoenician town when the Greeks occupied it in 331 B.C. They renamed it "Heliopolis" (City of the Sun). It became a Roman colony under the Emperor Augustus in 16 B.C..On its acropolis, over the course of the next three centuries, the Romans constructed a monumental ensemble of three temples, three coutyards, and an enclosing wall built of some of the most gigantic stones ever crafted by man. Some tourists believe that the construction can only be attributed to extra-terrestial artwork.
At the southern entrance of Baalbeck is a quarry where the stones used in the temples were cut. A huge block, considered the largest hewn stone in the world, still sits where it was cut almost 2,000 years ago. Called the "Stone of the Pregnant Woman", it is 21.5m x 4.8m x 4.2meters in size and weighs an estimated 1,000 tons.
During the Hellenistic period (333-64 B.C.) the Greeks identified the god of Baalbeck with the sun god and the city was called Heliopolis or City of the Sun. At this time the ancient enclosed court was enlarged and a podium was erected on its western side to support a temple of classical form. Although the temple was never built, some huge construction from the Hellenistic project can still be seen. And it was over the ancient court that the Romans placed the present Great Court of the Temple of Jupiter.

The Temples In History
For centuries the temples of Baalbeck lay under meters of rubble, obscured by medieval fortifications. But even in ruin the site attracted the admiration of visitors and its historical importance was recognized.
The first survey and restoration work at Baalbeck was begun by the German Archaeological Mission in 1898. In 1922 French scholars undertook extensive research and restoration of the temples, work which was continued by the Lebanese Directorate General of Antiquities.
Baalbeck's temples were built on an ancient tell that goes back at least to the end of the third millennium B.C. Little is known about the site during this period, but there is evidence that in the course of the 1rst millennium B.C. an enclosed court was built on the ancient tell. An altar was set in the center of this court in the tradition of the biblical Semitic high places.
Aerial view of the Acropolis
The temple was begun in the last quarter of the 1rst century B.C., and was nearing completion in the final years of Nero's reign (37-68 A.D.). the Great Court Complex of the temple of Jupiter, with its porticoes, exedrae, altars and basins, was built in the 2nd century A.D. Construction of the so-called temple of Bacchus was also started about this time. (more)
