In an ion exchange plant the water passes through a cation resin, which takes up the calcium and magnesium ions, and then through an anion resin, which takes up the sulphate, chloride and bicarbonate ions; because the hardness-causing ions are actually taken out of the water, the hardness can be…

As Director-General of the Archaeological Survey of India, John Marshall carried out long excavations at Taxila from 1913 onwards and published a detailed account of the city's successive settlements; the site was later inscribed on the UNESCO World Heritage List in 1980.

Ikhtiyaruddin Muhammad bin Bakhtiyar Khalji, a commander in the service of the Ghurids, overran Bihar at the end of the twelfth and the beginning of the thirteenth century and destroyed the monastic universities of the region, after which organised Buddhist learning in eastern India came to an end.

Later Tibetan accounts call the library of Nalanda Dharmaganja, the treasury of the law, and say that it consisted of three buildings named Ratnasagara, Ratnodadhi and Ratnaranjaka, the tallest of which is described as a nine-storeyed structure.

Valabhi, in the Saurashtra region of Gujarat, was the capital of the Maitraka rulers and a famous centre of Hinayana Buddhist learning; the pilgrim I-tsing wrote that it stood beside Nalanda in reputation, and students went from there into royal service.

Gopala, the founder of the Pala dynasty in the eighth century, established the Odantapuri monastery in the region of Bihar Sharif, and its plan is said to have been followed when the first monasteries were built in Tibet.

Atisha Dipankara Srijnana was the most famous teacher of Vikramashila, the Pala monastery at Antichak in Bhagalpur, and in the eleventh century he was invited to Tibet, where he reformed Buddhist practice and is remembered as one of its great masters.

The Chinese pilgrim Xuan Zang studied the Yogachara philosophy at Nalanda under Shilabhadra, who was then the aged head of the monastery, during the reign of Harshavardhana in the seventh century.

Takshashila, called Taxila by Greek and later English writers, was the capital of the Mahajanapada of Gandhara in the north-west of the subcontinent, in what is now the Rawalpindi district of Pakistan, and it was already a famous centre of learning in the time of the Buddha.

The Pala king Dharmapala founded Vikramashila at Antichak in the Bhagalpur district of Bihar about the turn of the ninth century, and it became famous for tantric studies and for the scholars called dvarapanditas who examined candidates at its gates.

The Gupta ruler Kumaragupta I founded the Nalanda Mahavihara in the fifth century of the Christian era near Rajgir in present-day Bihar, and a seal bearing his name has been found at the site.

Xuan Zang, also written Hiuen Tsang, travelled in India in the seventh century of the Christian era, during the reign of Harshavardhana of Kannauj, which is roughly fourteen hundred years before our own time.

In every real machine some of the work put in is used in overcoming friction between the moving parts and in lifting the parts of the machine itself, and that work leaves the system as heat and sound, so the work delivered to the load is always less than the…

A wedge is two inclined planes joined back to back, and an axe, a knife, a chisel and a nail all work on that principle: a force applied at the blunt end is turned into a much larger sideways force at the sharp edge, and the thinner and longer the…

The pitch of a screw is the distance between two consecutive threads measured along its axis, and it is also the distance through which the screw advances in one complete turn; the velocity ratio of a screw is the circumference of the circle described by the handle divided by the…

The velocity ratio of an inclined plane is the length of the slope divided by its vertical height, because the load is pushed along the whole slope while it is raised only through the height; here ten divided by two gives five, so in the ideal case an effort of…

In a single fixed pulley the rope that is pulled down moves exactly as far as the load rises, so the distance moved by the effort equals the distance moved by the load and the velocity ratio is one; the pulley gives no gain in force and is used only…

In a pair of tongs the joint is the fulcrum, the hand presses somewhere in the middle of the arms and the object held lies at the far end, so the effort is between the fulcrum and the load; the effort arm is shorter than the load arm, the mechanical…

In a wheelbarrow the wheel acts as the fulcrum, the load sits in the tray between the wheel and the hands, and the effort is applied at the handles, which is the arrangement of a second class lever; because the effort arm is always longer than the load arm, its…

A lever is a rigid bar turning about a fulcrum, and by the principle of moments the load multiplied by the load arm equals the effort multiplied by the effort arm, so a long effort arm lets a small effort balance a large load; this is the simplest way of…
