Coherer, iron and mercury: In 1899, the Bengali physicist Jagdish Chandra Bose announced the development of an "iron-mercury-iron coherer with telephone detector" in a paper presented at the Royal Society, London.[19] He also later received U.S. Patent 755,840, "Detector for electrical disturbances" (1904), for a specific electromagnetic receiver. Cotton gin, single-roller: The Ajanta caves of India yield evidence of a single roller cotton gin in use by the 5th century.[20] This cotton gin was used in India until innovations were made in form of foot powered gins.[21] The cotton gin was invented in India as a mechanical device known as charkhi, more technically the "wooden-worm-worked roller". This mechanical device was, in some parts of India, driven by water power.[4] Crescograph: The crescograph, a device for measuring growth in plants, was invented in the early 20th century by the Bengali scientist Jagadish Chandra Bose.[22][

Simputer: The Simputer (acronym for "simple, inexpensive and multilingual people's computer") is a self-contained, open hardware handheld computer, designed for use in environments where computing devices such as personal computers are deemed inappropriate. It was developed in 1999 by 7 scientists of the Indian Institute of Science, Bangalore, led by Dr. Swami Manohar in collaboration with Encore India, a company based in Bangalore.[69][70] Originally envisaged to bring internet to the masses of India, the Simputer and its derivatives are today widely utilized by governments of several Indian states as part of their e-governance drive, the Indian Army, as well as by other public and private organizations.[71][72] Snakes and ladders: Snakes and ladders originated in India as a game based on morality.[73] During British rule of India, this game made its way to England, and was eventually introduced in the United States of America by game-pioneer Milton Bradley in 1943.[73] Stepwell: Earliest clear evidence of the origins of the stepwell is found in the Indus Valley Civilization's archaeological site at Mohenjodaro in Pakistan.[74] The three features of stepwells in the subcontinent are evident from one particular site, abandoned by 2500 BCE, which combines a bathing pool, steps leading down to water, and figures of some religious importance into one structure.[74] The early centuries immediately before the common era saw the Buddhists and the Jains of India adapt the stepwells into their architecture.[74] Both the wells and the form of ritual bathing reached other parts of the world with Buddhism.[74] Rock-cut step wells in the subcontinent date from 200-400 CE.[75] Subsequently the wells at Dhank (550-625 CE) and stepped ponds at Bhinmal (850-950 CE) were constructed.[75] Stupa: The origin of the stupa can be traced to 3rd century BCE India.[76] It was used as a commemorative monument associated with storing sacred relics.[76] The stupa architecture was adopted in Southeast and East Asia, where it evolved into the pagoda, a Buddhist monument used for enshrining sacred relics.[76] Toe stirrup: The earliest known manifestation of the stirrup, which was a toe loop that held the big toe was used in India in as early as 500 BCE[77] or perhaps by 200 BCE according to other sources.[78][79] This ancient stirrup consisted of a looped rope for the big toe which was at the bottom of a saddle made of fibre or leather.[79] Such a configuration made it suitable for the warm climate of most of India where people used to ride horses barefoot.[79] A pair of megalithic double bent iron bars with curvature at each end, excavated in Junapani in the central Indian state of Madhya Pradesh have been regarded as stirrups although they could as well be something else.[80] Buddhist carvings in the temples of Sanchi, Mathura and the Bhaja caves dating back between the 1st and 2nd century BCE figure horsemen riding with elaborate saddles with feet slipped under girths.[81][82][83] Sir John Marshall described the Sanchi relief as "the earliest example by some five centuries of the use of stirrups in any part of the world".[83] In the 1st century CE horse riders in northern India, where winters are sometimes long and cold, were recorded to have their booted feet attached to hooked stirrups.[78] However the form, the conception of the primitive Indian stirrup spread west and east, gradually evolving into the stirrup of today.http://en.wikipe

They lived in beautiful homes, employed great artists, and engaged in intellectual pursuits for both business and pleasure.

One of the cities that exemplified these new trends was Florence.

Greece consists of a large mainland at the southern end of the Balkans; the Peloponnesus peninsula (separated from the mainland by the canal of the Isthmus of Corinth); and numerous islands (around 3,000), including Crete, Rhodes, Kos, Euboea and the Dodecanese and Cycladic groups of the Aegean Sea as well as the Ionian sea islands. Greece has more than 15,000 kilometres of coastline and a land boundary of 1,160 kilometres.

high range, the Rhodope, located in Eastern Macedonia and Thrace

Mount Olympus forms the highest point in Greece at 2,919 metres above sea level.

covered with vast and thick century old forests like the famous Dadia

Plains are mainly found in Eastern Thessaly, Central Macedonia and Thrace.Greece's climate is divided into three well defined classes the Mediterranean, Alpine and Temperate, the first one features mild, wet winters and hot, dry summers. Temperatures rarely reach extremes, although snowfalls do occur occasionally even in Athens, Cyclades or Crete during the winter.

Alpine is found primarily in Western Greece

temperate climate is found in Central and Eastern Macedonia as well as in Thrace at places like Komotini, Xanthi and northern Evros; with cold, damp winters and hot, dry summers.

About 50% of Greek land is covered by forests with a rich varied vegetation which spans from Alpine coniferous to mediterranean type vegetation.

Seals, sea turtles and other rare marine life live in the seas around Greece, while Greece's forests provide a home to Western Europe's last brown bears and lynx as well as other species like Wolf, Roe Deer, Wild Goat, Fox and Wild Boar among others.

According to this information, there would have been many villages, hamlets, single farms, and occasional small towns scattered over the land; as can still be seen in Crete.

The land was organized for mules and donkeys with built mule-tracks reaching every settlement.

Ancient Greeks became a sea-going people due to the close proximity of the sea to most Greek city-states. These merchants and traders developed a sense of freedom and independence not seen before.

Estimates of the population of ancient Athens vary. During the 4th century BC, there may well have been some 250,000–300,000 people in Attica. Citizen families may have amounted to 100,000 people and out of these some 30,000 will have been the adult male citizens entitled to vote in the assembly. In the mid-5th century the number of adult male citizens was perhaps as high as 60,000, but this number fell precipitously during the Peloponnesian War.

"We are not allowed that!"

but the sin of television, which they encountered at the geologists' camp, proved irresistible for them.... On their rare appearances, they would invariably sit down and watch. Karp sat directly in front of the screen. Agafia watched poking her head from behind a door. She tried to pray away her transgression immediately—whispering, crossing herself.... The old man prayed afterward, diligently and in one fell swoop.

developed at an unprecedented speed during the 5th century BC, continuing up to and including the Roman period, and beyond. Inventions that are credited to the ancient Greeks    such as the gear, screw, rotary mills, screw press, bronze casting techniques, water clock, water organ, torsion catapult and the use of steam to operate some experimental machines and toys and a chart to find prime numbers . Many of these inventions occurred late in the Greek period, often inspired by the need to improve weapons and tactics in war.       How ever, peaceful uses are shown by their early development of the watermill , a device which pointed to   further exploitation on a   large scale under the Romans
