What is Thinking -why it is important

In science, cognition is a group of mental processes that includes attention, memory, producing and understanding language, solving problems,Thinking and making decisions. Cognition is studied in various disciplines such as psychology, philosophy, linguistics, science and computer science. The term’s usage varies in different disciplines; for example in psychology and cognitive science, it usually refers to an information processing view of an individual’s psychological functions. It is also used in a branch of social psychology called social cognition to explain attitudes, attribution, and groups dynamics. There are various things people can…

why is the speed of light important

why is the speed of light important

The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is 299792458 metres per second (approximately 3.00×108 m/s, approximately 186,282 mi/s) since the length of the metre is defined from this constant and the international standard for time. According to special relativity, c is the maximum speed at which all matter and hence information in the universe can travel. It is the speed at which all massless particles and changes of the associated fields (including electromagnetic radiation…

All you need to know is mingling of molecules

All you need to know is mingling of molecules

If we were to go back to our convenient imaginary switchboard to turn off another law, we should find near the heat switches, and not far from the chemistry ones, a switch labeled SOLUTION. Suppose we turned it off: The fishes in the sea are among the first creatures to be surprised by our action. For instantly all the salt in the ocean drops to the bottom like so much sand, and most salt-water fishes soon perish in the fresh water. If some one is about to drink a cup…

Things you should know about powerful electricity

Things you should know about powerful electricity

The Greeks, 2000 years ago, knew that there was such a thing as electricity, and they used to get it by rubbing amber with silk. In the past century men have learned how to make electricity do all sorts of useful work: making boats and cars and automobiles go, ringing bells, furnishing light, and, in the telephone and telegraph, carrying messages. But no one knew what electricity really was until, within the last 25 years, scientists found out. ATOMS AND ELECTRONS When we talked about molecules, we said that they…

why elasticity is more than you think

why elasticity is more than you think

  Elastic Suppose there were a man who was perfectly elastic, and who made everything he touched perfectly elastic. Fortunately there is no such person, but suppose an elastic man did exist: He walks with a spring and a bound; his feet bounce up like rubber balls each time they strike the earth; his legs snap back into place after each step as if pulled by a spring. If he stumbles and falls to the ground, he bounces back up into the air without a scar. (You see, his skin…

Scientists have set a new world record for plasma pressure

Scientists have set a new world record for plasma pressure

Scientists have set a new world record for plasma pressure – the ‘key ingredient’ for producing energy from nuclear fusion – which means this clean and sustainable energy source is closer to our grasp than ever before. The new record stands at 2.05 atmospheres – a 15 percent jump over the previous record of 1.77 atmospheres. Both this record and the last were set at the custom-built Alcator C-Mod reactor at MIT. While a viable nuclear fusion reactor ready to power our homes is still a long way off, these…

It is a really amazing discovery

It is a really amazing discovery

DENVER—Some 56 million years ago, carbon surged into Earth’s atmosphere, raising temperatures by 5°C to 8°C and causing huge wildlife migrations—a scenario that might mirror the world’s future, thanks to global warming. But what triggered this so-called Paleocene-Eocene thermal maximum (PETM) has remained a mystery. Now, in new work presented on 27 September at the annual meeting of the Geological Society of America and published this week in Science, a group of scientists bolsters its claim that a small comet impact kicked off the PETM, stirring up the carbon just…

Advantages and disadvantages of nano technology

Nanotechnology Over the past ten years scientists have developed various kinds of nano technologies. which are helpful for us in many ways.But it has its merits and also having some demerits. Nanotechnology has the ability to help us in so many ways, Over the last ten years, scientists have worked hard to modify and develop the nanotechnology, and it has paid off. Some are in the process of developing nano scale patterns on implants that can stimulate bone cell growth and positive gene expression, while others are creating guided nano…

SCIENCE FACT Literary Moons All 27 moons of Uranus are named after characters created by William Shakespeare and Alexander Pope (specifically from his poem, “The Rape of the Lock”). Its five largest moons are Titania, the eighth-largest moon in the solar system, and Oberon, both discovered by William Herschel in 1787, six years after he realized Uranus was neither a star nor a comet; Umbriel and Ariel, discovered in 1851; and Miranda, with its unusual geographic scarring, found in 1948. The first four moons were all named by Herschel’s son,…
