Scientific and Critical Thinking. When one uses thescientific method to study or investigate nature or the universe, one is practicing scientific thinking. Allscientists practice scientific thinking, of course, since they are actively studying nature and investigating the universe by using the scientificmethod.Jan 15, 1997 


Biology is the study of living things. It encompasses the cellular basis of living things, the energy metabolism that underlies the activities of life, and the genetic basis for inheritance in organisms. … Types of practical biology include plant breeding, wildlife management, medical science, and crop production.

Organic chemistry is the study of the structure, properties, composition, mechanisms, and reactions of organic compounds. An organic compound is defined as any compound based on a carbon skeleton. Physical chemistry is the study of the physical and fundamental basis of chemical systems and processes.

Cricket is a bat-and-ball game played between two teams of eleven players each on a cricket field, at the centre of which is a rectangular 22-yard-long pitch with a target called the wicket (a set of three wooden stumps upon which two bails sit) at each end. Each phase of play is called an innings during which one team bats, attempting to score as many runs as possible, whilst their opponents field. Depending on the type of match, the teams have one or two innings apiece and, when the first innings ends, the teams swap roles for the next innings. Except in matches which result in a draw, the winning team is the one that scores the most runs, including any extras gained.

Before a match begins, the two team captains meet on the pitch for the toss (of a coin) to determine which team will bat first. Two batsmen and eleven fielders then enter the field and play begins when a member of the fielding team, known as the bowlerdelivers (i.e., bowls) the ball from one end of the pitch towards the wicket at the other end, which is guarded by one of the batsmen, known as the striker. In addition to the bowler, the fielding team includes the wicket-keeper, a specialist who stands behind the striker’s wicket. The nine other fielders are tactically deployed around the field by their captain, usually in consultation with the bowler. The striker “takes guard” on a crease marked on the pitch four feet in front of the wicket. His role is to prevent the ball from hitting the stumps by using his bat and, simultaneously, to strike it well enough to score runs. The other batsman, known as the non-striker, waits at the opposite end of the pitch near the bowler. The bowler’s objectives are to prevent the scoring of runs and to dismiss the batsman. A dismissed batsman, who is declared to be “out”, must leave the field to be replaced by a teammate. An over is a set of six deliveries bowled by the same bowler. The next over is bowled from the other end of the pitch by a different bowler.Image result for cricket informationImage result for cricket informationImage result for cricket information

wind energy powerplant


Wind power is the use of air flow through wind turbine to mechanically power generators for electric power. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land.The net effects on the environment are far less problematic than those of nonrenewable power sources.Image result for wind energy power plant

Wind farms consist of many individual wind turbines which are connected to the electric power transmission network. Onshore wind is an inexpensive source of electric power, competitive with or in many places cheaper than coal or gas plants.Offshore wind is steadier and stronger than on land, and offshore farms have less visual impact, but construction and maintenance costs are considerably higher. Small onshore wind farms can feed some energy into the grid or provide electric power to isolated off-grid locations.

Wind power gives variable power which is very consistent from year to year but which has significant variation over shorter time scales. It is therefore used in conjunction with other electric power sources to give a reliable supply. As the proportion of wind power in a region increases, a need to upgrade the grid, and a lowered ability to supplant conventional production can occur. Power management techniques such as having excess capacity, geographically distributed turbines, dispatchable backing sources, sufficient hydroelectric power, exporting and importing power to neighboring areas, or reducing demand when wind production is low, can in many cases overcome these problems. In addition, weather forecasting permits the electric power network to be readied for the predictable variations in production that occur.

As of 2015, Denmark generates 40% of its electric power from wind,and at least 83 other countries around the world are using wind power to supply their electric power grids. In 2014, global wind power capacity expanded 16% to 369,553 MW. Yearly wind energy production is also growing rapidly and has reached around 4% of worldwide electric power usage, 11.4% in the Image result for wind energy power plant

the word “HYDRO” means water,so it is creating electricity using this process the waste water can be purified and used again.this is a non-conventional source of energy.a dynamo or a toy car motor by moving it we can produce electricity.A turbine is also needed.

5 Indian scientists whose work shaped modern life

1Chandrasekhara V Raman

CV Raman was not only a great scientist but also believed in social development. In 1930, he won the Nobel Prize for Physics becoming the first Asian to do so. He is associated with the concept of Raman’s Effect, which says that when a light passes through a transparent substance, it scatters.

2Dr Jagadish Chandra Bose

Dr Jagadish Chandra Bose is famous for the invention of theCrescograph that can record even the millionth part of a millimetre of plant growth and orbital movement.

3Dr Homi Jehangir Bhabha

Dr Homi Jehangir Bhabha joined the Indian Institute of Sciences at Bangalore as a Reader at the request of Dr C V Raman.

4Dr Vikram Ambalal Sarabhai

Dr Vikram Ambalal Sarabhai was the key person behind the launch of India’s first satellite ‘Aryabhatta’. His studies of cosmic rays have made it evident that cosmic rays are a flow of energy particles with its source in outer space. On their way to earth, they are influenced by solar energy, and the earth’s atmosphere and magnetism

5Dr A P J Abdul Kalam

Dr A P J Abdul Kalam, the eleventh President of India, was born on October 15, 1931. He was awarded the Bharat Ratna in 1997 for his contributions in the field of science and engineering. He developed the Satellite Launch Vehicle (SLV 3) at the Vikram Sarabhai Space Centre, which put the satellite Rohini into orbit.

When you drive toward an intersection, the sight of the light turning red will (or should) make you step on the brake. This action happens thanks to a chain of events inside your head.
