Science is the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. In simple terms, science is what we do to find out about the natural world. It is the total of physics, chemistry, biology, geology and astronomy and related areas. Science makes use of mathematics, and it makes observations and experiments. Science produces accurate facts, scientific laws and theories. 'Science' also refers to the large amount of knowledge that has been found using this process called the scientific methods.  Science is curiosity in thoughtful action about the world and how it behaves. If an idea, or hypothesis, correctly predicts how something will behave, it is called a theory. People who study and research science and try to find out everything about it are called scientists. Scientists study things by looking at them very carefully, by measuring them, and by doing experime...

          5 Amazing Science   Facts That Will Blow Your Mind 1. There is enough DNA in the average person’s body to stretch from the sun to Pluto and back — 17 times The  human genome  (the genetic code in each human cell) contains 23 DNA molecules (called chromosomes), each containing from 500,000 to 2.5 million nucleotide pairs. DNA molecules of this size are 1.7 to 8.5 cm long when uncoiled — about 5 cm on average. There are about  37 trillion cells  in the human body, so if you were to uncoil all of the DNA encased in each cell and place the molecules end to end, it would sum to a total length of 2×10 14  meters —  enough for 17 Pluto round-trips  ( t he distance from the sun to Pluto and then back again is  1.2×10 13  meters). As an added bonus, you should know that we each share 99% of our DNA with every other human — just to show that we’re far more alike than different. 2. The average...

History of Nobel prize Nobel awards had started giving in the name of Alfred Nobel from 1901 onwards. It is given in six areas such as literature,peace,biology,physics,chemistry,economics. Nobel for economics started from 1969 onwards. It is based on the 300th anniversary of riks bank of Switzerland. Therefore this prize also known as bank of Sweden prize. It is the only award which have no connection with Alfred Nobel. The prize is distributed for winners in Stockholm,the capital of Switzerland except for peace. It is on death anniversary of Alfred, December 10.

what happens to our body when we are in angry???? When   we   get   angry , the heart rate, arterial tension and testosterone production increases, cortisol (the stress hormone) decreases, and the left hemisphere of the brain becomes more stimulated. ... There is an increase in heart rate, arterial tension and testosterone, but the cortisol level decreases.

The Beckmann rearrangement named after the German chemist Ernst Otto Beckmann is a rearrangement of oxime functional group to substituted amides .The rearrangement has also successfully performed on nitrons and haloimines .Cyclic oximes and haloimines yield lactams. This rearrangement is often catalysed by acid ,however other reagentshave been known to promote  the rearrangement .These include tosyl chloride,thionyl chloride,phosphorus pentachloride,phosphorus pentoxide,tri ethyl ammine.                                              Clubscience                                              Ryan Rahman

The skin as a sense organ,perceives all kind of touch sensations as signals.These signals are sent to brain ,are interpreted and the body reacts accordingly.The brain can differentiate between the touch stimuli that we create ourselves and stimuli given by others .If we try to tickle ourselves ,our brain anticipates this type of touch from our hands and prepare itself for it.Since the element unexpectedness is missing ,the body does not respond the same way as it would if someone else were to tickle                                            Clubscience                                            Ryan Rahman

Hawkings radiation is a black body radiation that is predicted to be released from black holes,due to quantum effect near the event horizon.It is named after English physicist Stephen Hawking who provided theoretical argument for its existence in 1974.Hawkings work helped to explain the result of Jacob Bekenstein who had predicted that black hole should have finite entropy. Hawkings radiation reduces the mass and energy of black hole and is known as BLACK HOLE EVAPORATION .Because of this black hole dont gain mass through other means are expected to shrink and vanish.This is abroad topic which is with many theories and predictions.                                         Clubscience                                         Ryan Rahman

In polar regions like Alaska  and Northern Canada a splendid display of colours is seen in the sky.An explanation for this phenomenon is: During a solar flare ,a large number of electrons and protons are ejected from the sun.Some of them get trapped in the earth's magnetic field and move in helical path along the field lines .The field lines come closer to each other near the magnetic poles .Hence the density of charges increases near the poles .These particles collide with atoms and molecules of the atmosphere.Excited oxygen atoms emit green light and excited nitrogen atoms emits pink light.This phenomenon is called Aurora Borealis in physics                                                        Clubscience                                    ...

A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.                                                 Quark , any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter. Quarks associate with one another via the strong force to make up protons and neutrons, in much the same way that the latter particles combine in various proportions to make up atomic nuclei. There are six types, or flavours, of quarks that differ from one another in their mass and charge characteristics. These s...
