Heat is energy transfer to or from a thermodynamic system, by mechanisms other than a transfer of matter such as conduction, radiation, and convection or thermodynamic work. Heat transfer involves the surroundings of a system, as well as the system itself. But it is not a property of the system alone, even though it contributes to change in […]
Insect venoms are indeed complicated. You could be exonerated for thinking that it will be relatively a simple composition of chemicals which creates an aching sensation during a bee or wasp sting, but the fact is that, it’s a highly complex mixture of all classes of compounds – proteins, peptides, enzymes, and many other smaller […]

A shooting star is really a meteoroid, a fragment of an asteroid or a comet, made up of iron, silicates or a mixture of both. When the meteoroid is caught in the earth’s gravitational pull, it is drawn through the earth’s atmosphere at a very high speed. Speed so high, that the friction with the […]
Borromean rings are three simple closed curves in three-dimensional space .These rings are topologically linked and they cannot be separated from each other. But when any one of the three rings break or is removed ,we get two unlinked and unknotted loops. These rings can be drawn as three circles on a plane. It looks […]
Global warming happens when the earth heats up (the temperature rises) to more than normal range. It happens when greenhouse gases (carbon dioxide, water vapour, nitrous oxide and methane) trap terrestrial radiation in the Earth’s atmosphere, which increases the temperature. This temperature increase can have paradoxical effects, such as more frequent and severe snowstorms. Climate […]

As they grow, each polyp produces a hard, limestone skeleton, on which the next generation of polyps […]
