By the eleventh century, there is evidence of several technological changes :
1. Instead of the basic wooden ploughs, cultivaros began using heavy iron-tipped ploughs and mould-boards. These ploughs could dig much deeper and the mould-boards turned the topsoil properly. With this the nutrients from the soil were better utilised.

2. The methods of harnessing animals to the plough improved. Instead of the neck-harness came into use. This enabled animals to exert greater power. Horses were now better shod, with iron horseshoes, which prevented foot decay.

There was increased use of wind and water energy for agriculture. More water-powered and wind-powered mills were set up all over Europe for purposes like milling corn and pressing grapes.

3. There were also changes in land use. The most revolutionary one was the switch from a two-field system. In this, peasants could use a field two years out of three if they planted it with one crop in autumn and a different crop in spring a year and a half later.
That meant that farmers could break their holdings into three fields. They could plant one with wheat or rye in autumn for human consumption.
The second could be used in spring to raise peas, beans and lentils for human use, and oats and barley for the horses. The third field lay fallow. Each year they rotated the use among the three fields.

With these improvements, there was an almost immediate increase in the amount of food produced from each unit of land. Food availability doubled. The greater use of plants like peas and beans meant more vegetable proteins in the diet of the average European and a better source of fodder for their animals.

4. Some of these technological changes cost a lot of money. Peasants did not have enough money to set up watermills and windmills. Therefore the initiative was taken by the lords. But peasants were able to take the initiative in many things, such as extending arable land.

Radioactive elements are made up of atoms whose nuclei are unstable and give off atomic radiation as part of a process of attaining stability. The emission of radiation transforms radioactive atoms into another chemical element, which may be stable or may be radioactive such that it undergoes further decay.

Valence shell electron pair repulsion theory, or VSEPR theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. It is also named the Gillespie-Nyholm theory after its two main developers, Ronald Gillespie and Ronald Nyholm.

The enthalpy of vaporization, also known as the heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.

Buddhism

Jainism

Rebirth is one of the principal beliefs in Buddhism. It is thought that the endless cycle of birth and re-birth can only be broken by attaining <i>Nirvana </i>(Enlightenment) Jainism believes that the circle of rebirths and deaths will continue due to good or bad deeds until liberation is achieved
Scriptures include <i>Tripitaka</i>, which is a vast text consisting of 3 sections: the Discipline, the Discourse and the Commentaries.  Jain religious texts are called <i>Agamas</i>
The principal teaching of Buddhism is that life is suffering and to escape suffering (end cause of desire) one needs to dispel ignorance by realizing the Four Noble Truths and practising the Eightfold Path Jainism lays emphasis on the respect of all living beings. Liberation from the cycle of rebirths is attained by taking the Five Vows and following the principles of the Three Jewels
Sin is not a concept in Buddhism Sin is defined as harm to others
Buddhism is divided into two major sects upon the death of Gautama Buddha. They are the Mahayana and the Theravada  Svetambara and Digambara are the two major sects of Jainism
According to some texts in Buddhism, there are beings in heaven but they are bound by “<i>samsara”</i>. They suffer less bu they ave, not yet achieved salvation Deities in Jainism are known as <i>“Titrtheneakas”. </i> But they are not worshipped in the conventional sense as they are regarded as wise teachers whose teachings must be followed
Buddhism was founded in modern-day Nepal by Prince Siddhartha in the 6th century B.C Scholars of religion generally hold that Jainism originated in the 7th–5th century BC in Northern India. Mahavira, also known as Vardhamana was the 24th Tirthankara (Spiritual Teacher) of Jainism
Followers of Buddhism can be found mainly in Thailand, Cambodia, Sri Lanka, India, Nepal, Bhutan, Tibet, Japan, Myanmar (Burma), Laos, Vietnam, China, Mongolia, Korea, Singapore, Hong Kong and Taiwan Followers of Jainism are found mainly in India, lower Asian subcontinent throughout, and America. Small groups exist in most countries

Work is said to be done when a force applied to an object moves that object.

We can calculate work by multiplying the force by the movement of the object.

W = F × d

The SI unit of work is the joule (J)
