Bhakra Dam

 The Bhakra Dam is India’s biggest hydro electric project. It is located near the border of Punjab with Himachal Pradesh. The dam has been constructed across the perennial river Sutlej, which flows down the Shivalik ranges that surrounds the region, and is an engineering marvel. It is one of the highest gravity dams in the world, and it has created a huge reservoir known as the Gobind Sagar reservoir. This dam is virtually the central nervous system of northern India, as it supplies electricity to the entire region.

Why has Punjab seen many divisions in its history?

Punjab, ‘the land of five rivers’, was one of the centres of the prehistoric Indus valley Civilization. After 1500 BC, it was the site of the earliest Aryan settlements. In the past, Punjab was occupied by Alexander the Great, and then by the Mauryan Empire. Muslims occupied West Punjab by the 8th century, and ushered in Islam. Not until the late 12th century, did they conquer East Punjab, which even afterward, remained predominantly Hindu. In the late 18th century, the Sikhs rose to dominance. They came into conflict with the British during the early 19th century. In 1849, the British annexed most of the Punjab, and made it a province, though some of the princely states were retained.With the creation of Pakistan in 1947, Punjab was partitioned according to the prevalence of Muslim and the Hindu populations. The western portion became part of Pakistan. The eastern part stayed with India. The Indian Punjab was divided into three different states on a linguistic basis on November 1st 1966. The Hindi speaking areas formed the new state of Haryana, while the Northern most districts were transferred to Himachal Pradesh. The remaining regions form present day Punjab.

Golden Temple

 The holiest shrine of the Sikhs is the Golden Temple at Amritsar. The location of the Golden Temple was originally a small lake in a deep forest. It has long been recognized as a place of spiritual significance. It is said that Buddha spent some time there, and later, the first Sikh Guru meditated at the lake. The architecture of the Golden temple represents a unique harmony between Muslim and Hindu styles.

Konark Dance Festival

The Konark Sun Temple in Odisha was built in the 13th century. It was conceived as a gigantic solar chariot with twelve pairs of exquisitely – ornamented wheels dragged by seven rearing horses. The exquisite ‘natamandir’ or the ‘dancing hall’ of this shrine is an architectural wonder. The Konark Dance Festival is held in December every year, against the beautiful backdrop of this temple. A host of celebrated classical dancers from all over the country perform in the open-air auditorium. The festival provides a platform for both the performing artistes and the dance connoisseurs to appreciate the essence of various classical dance forms of the country.

Ants do not get hurt when they fall. Why?

            The fall of a body is controlled mainly by gravitational attraction of the Earth. The gravitational force depends on the mass of the falling object-a heavier object is attracted more than a lighter object. This attractive force is opposed by an upward thrust (resistance) offered by air on the body. This resistance also depends on the surface area of the object. That is, if the surface area is more, the resistance is also more. Thus in any falling object, these two forces compete with each other.

            In the case of an ant, the force of gravity is almost balanced by air resistance and so it is able to land safely. If there is a wind blowing, ants also float away. However, if a cluster of ants or a big ant is forcibly hurled to the ground, they will get hurt. Anyway, it will be difficult to know whether the ant gets hurt or not.

Sand Art

Odisha is famous for the art of sand sculptures. According to belief, a famous poet Balaram Das wanted to climb Lord Jagannath’s chariot during the Rath Yatra, but was not allowed. Saddened, he then went to the beach, and carved the images of Lord Jagannath, Devi Subhadra of Lord Balabhadra on the golden sand and prayed to these images.

What do we know about the geography of Odisha?

Odisha lies on the eastern coast of India. It is bounded by West Bengal in northeast, Jharkhand in the north, Madhya Pradesh in the west, Andhra Pradesh in the south, and the Bay of Bengal in the east. Orissa can be divided into three broad regions – the coastal plains, the middle mountainous country and the plateaus. The region of the coastal plains is a combination of several deltas formed by the major rivers of Odisha, such as the Subarnarekha, the Budhabalanga, the Baitarani, the Brahmani, the Mahanadi, and the Rushikulya. The middle mountainous region covers about three-fourths of the entire state and comprises the hills and mountains of the Eastern Ghats. The plateaus are mostly eroded tablelands, forming the western slopes of the Eastern Ghats.   To sum up, the state offers diverse habitats from lush green and hilly terrain, to coastal plains and rolling river valleys, criss-crossed by rivers that include the Brahmani, the Mahanadi and the Bansadhara.

How do ants find their way to hidden sweets?

            Antennae, the two hair-like structures on the head of the ants, help them in locating sweets. These chemoreceptor’s help them to perceive smell and taste through minute sensilla, or sensory cells.

             These sensilla can detect accurately the smell in the air. It points towards the origin of the smell by detecting accurately the changes in the concentration of the odoriferous particles. If the sweets are wrapped in paper bags or any other wrappers having minute holes, the odour carried by the air will be sensed by the sensilla. If the antennae are removed, ants cannot identify the smell and distinguish them from other foods.

Why did the Kalinga war have a great impact on the history of Odisha?

In ancient times, Odisha was known as Utkala, Kalinga and Odra Desa at different points in its history. For many centuries, Kalinga was a very powerful kingdom. The famous war that the Emperor Asoka waged against Kalinga proved to be a turning point in his life. The bloodshed and killing of war sickened him, and led him to renounce violence, and turn to Buddhism. This war had a great impact on the history of this region too, for under Asoka’s benevolent guidance, literature, language, music, and dance flourished here during ancient times. In 1568, the last Hindu ruler was over-thrown by a Muslim general, and finally, Odisha was annexed by Akbar in 1592. The Mughals ruled till 1803, when Odisha came into British possession. Following India’s independence, the 26 princely states in the region were merged into modern state of Odisha.
