Our universe is a vast open space comprising of the stars, star systems and the galaxies. It has been a subject of discussion amongst many astronomers, cosmologists and scientists. They have tried to estimate the exact age of the universe and the way it came in to existence. As no one was physically present at [...]
The beautiful big white moon that we see on its full moon days looks very beautiful from such a vast distance. It triggers many questions in our mind. How was the moon formed? Is it made up of the same material as our earth is? What went in to its evolution? With all these questions [...]
Have you ever wondered how our beautiful planet Earth has formed? How its flowing rivers, heightened mountains and green nature has formed? How its tough exterior came in to existence? It sure seems that the making of earth must have been a big task as this is the only planet having life on it. Although [...]
When iron corrodes by coming in contact with water and oxygen rust is formed. As soon as rust surfaces it must be removed as it then leads to decay of the material it has affected. Once started, rust spreads easily. The rust can be brushed away with sandpaper. A layer of antirust solution must then [...]
Most people discard objects having rust stains on them, thinking that they are of no use anymore. This is far from the truth. Rust stains are removable. No matter which object they affect it is possible to get rid of them. If rust stains have spoilt your clothes there are a few ways to fight [...]
The uppermost layer of earth’s crust is known as soil. Weathering of rocks, metamorphosis, and chemical processes leads to formation of soil. Thus soil can be called rock in its final state of decay. Soil formation is a very slow process which can even take thousands of years. Soil which is found lying in the [...]
Snow is a form of precipitation that occurs in the form of crystalline water ice. It consists of multitude of snowflakes that fall from clouds. The precipitation of crystalline water ice leads to the formation of snow. Snow is considered as a granular material since it contains tiny particles. Snowflakes come in a variety of [...]
The Taj Mahal, one of the new Seven Wonders of the World, is perhaps the most beautiful and exquisite symbol of love. It was built in Agra by Mughal Emperor, Shah Jahan as a mausoleum for his wife, Mumtaz Mahal, over 350 years ago. It has been exquisitely built with marble, turquoise, jade, lapis lazuli [...]
A magnet is an object which creates a magnetic field around it. The characteristics of the magnet determine the weak to the strong fields of the same around it. Magnets can be categorized into two parts which are as follows: • Permanent magnets: They are magnetized and would remain magnetized for the lifetime. • Electro [...]
The uses of iron are innumerable. It is probably the most important metal for the human race, which has discovered its uncountable uses since 3500 B.C. Pure iron, a grayish white metal, is scarce on Earth. It is only available in fallen meteorites. Apart from that, the iron on earth is found as a combination [...]
Glass, perhaps, comprises of one of the largest part of industrial and domestic waste materials. With food bottles, show pieces and broken glass wares and light bulbs etc., the magnitude of the waste can be scarcely imagined. Glass in itself is a non-toxic, inert material. It is not really hazardous when it is dumped but [...]
The principle used to generate electricity came into existence during the late 1820 and the early years of 1830. The principle was discovered by Michael Faraday. The basic method that he invented is still used today. His principle stated that electricity is generated when there is a movement of a loop wire or copper disc [...]
Electrical resistance is the resistance to the flow of electrical current. This theory was discovered by George Ohm in the 19th century. Resistance is measured in ohms. Electricity is nothing but electrons flowing. In an electrical current, the atoms in the material allow the flow of electrons. If there is poor conductivity it means that [...]
Food is an important requirement not only for human beings but even for plants and animals. All living organisms require food to survive and therefore, storage of food is also very important. Plastids are special structures inside the plant cell that helps in storing food for the plants. Plastids are also found in different algae, [...]
We live in the age of plastics and hence most of the things that we use today are made up of different kinds of plastics. Plastics are synthetic or semi-synthetic organic solids. There are many kinds of plastics available that differ because they have different molecular mass. Plastics are very flexible and therefore, you can [...]
We have all heard about different chemical compounds like baking soda, carbon dioxide and calcium chloride but do we really know what exactly these chemical compounds are. Chemical compounds are chemical substances, which are made up of two or more chemical elements. Since every chemical compound is made up of two or more chemical elements [...]
Are you interested in learning more about chemical substances and how they are made? If you are then you must definitely know more about chemical reactions because chemical reaction is a process where chemical substances transform from one substance to another. Chemical reaction is a process in which electrons are constantly breaking and forming to [...]
Prime numbers are a set of unusual numbers that cannot be divided with any other number except 1 and the number itself. Hence, numbers like 2, 3, 5, and 7 are considered as prime numbers because you can only divide them either by using 1 or by the same number. All the prime numbers are [...]
Platelets are small red cells that are generally found in human and animal blood. Platelets are also known as thrombocytes, and they do not have a specific shape. If the count of platelets in your blood is too high then you might have problems like frequent blood cots that might lead to problems like heart [...]
Plasmid is a kind of DNA molecule that is found in bacterial DNA, and it is mostly used for genetic engineering. Many bacteria have these small circular objects that are found inside the cytoplasm of the bacteria, and they are called as plasmids. Although they are found in the bacterial cell, they are different and [...]
